TY - CHAP A1 - Wolff, Ian T1 - The Role of Universities of Applied Sciences in the Development of a national Research Data Infrastructure N2 - The presentation highlights the role of Universities of Applied Sciences (UAS) in research and their potential for the development of a National Research Data Infrastructure (NFDI). To address the growing need for structured research data management (RDM) at UASs, the FDM@HAW network has emerged as a potential connector between NFDI and UAS landscape. It aims to raise awareness of NFDI services across a diverse UAS network, and articulate UAS-specific requirements back to NFDI. In doing so, it strengthens mutual integration and fosters targeted support. With over 200 institutions [1], UASs constitute a significant part of the German science system. Traditionally focused on teaching, UASs have become drivers of applied research and regional innovation. Their contributions to education and research make them essential actors in shaping RDM in Germany. Research at UASs benefits business, science, and society. In many federal states, the right to award doctorates further reinforces their research activities. Strengthening RDM competencies is important to ensure that valuable research data from UAS meet the FAIR principles. Furthermore, employers benefit from graduates equipped with strong data literacy. Despite their potential, UASs remain underrepresented in the NFDI (and partly in the RDM community). Low participation in NFDI consortia and limited association membership indicate a broader lack of engagement, largely due to low awareness of NFDI among UAS researchers and administrations [2, p.42] [3, p.6]. The NFDI structure report 2024 addresses this gap and calls for broader contact to UASs [4, p.27]. Structural challenges limit UAS engagement in RDM and the NFDI, including high teaching loads, minor resources, and partnerships prioritizing data protection over openness or commercial interests. In response, many UASs have implemented strategic networking in research, teaching, and infrastructure to overcome resource limitations. This approach also drives the development of RDM structures, often via projects or state-level initiatives. The Federal Ministry of Education and Research supports 14 projects [5] through its funding guideline for RDM at UASs. This initiative led to the establishment of the FDM@HAW network in 2023, connecting these projects. Since its formation, the network has engaged in continuous exchange on RDM development and contributed to events such as Love Data Week, the FORTRAMA conference [6], Volkswagen Foundation's Digital Skills in Science Week [7] and E-Science-Tage [8]. These activities have helped sharpen the network's focus, identify shared priorities and integrate new members. Members contribute ideas, tools and services developed in RDM projects or collaborations - such as the "NFDI Survival Kit" [9] and the "NFDI-N(HAW)igator" [10] - to promote RDM awareness and inform about NFDI on a national scale. In line with NFDI's mission to "improv[e] the possibilities for using data for science and society" [11], FDM@HAW seeks to disseminate knowledge of and strengthen competence in delving into these possibilities. The network provides valuable support to activate a target group that has largely been untapped. Close cooperation between NFDI and FDM@HAW will then contribute to the successful development of a nationwide RDM ecosystem. In the presentation, proposals for cooperation will be outlined.

Wie digitale Souveränität gelingt N2 - Forschungsdatenmanagement (FDM) ist in der Fläche angekommen und in aller Munde. Überall in Deutschland, Europa und international werden FDM-spezifische Dienste und Services aufgebaut. Solche Strukturen auch an kleineren und mittleren Hochschulen dauerhaft anzubieten, ist aus unterschiedlichen Gründen herausfordernd und geht nur in enger Kooperation. Der Artikel beschreibt, wie die Hochschulen in Brandenburg den Weg hin zu einer Institutionalisierung von FDM beschreiten in einem Spannungsfeld, welches sich wie folgt darstellen lässt: So gemeinsam wie möglich - doch mit den lokalen Spezifika weiter im Blick.

Der Verbund besteht aus vier Universitäten und vier Hochschulen für Angewandte Wissenschaften[1]. Zur Weiterentwicklung von Strategien und Unterstützungsangeboten zum Forschungsdatenmanagement (FDM) – sowohl an jeder Hochschule als auch gemeinsam für Brandenburg – ist es wichtig, aktuelle FDM-Kenntnisse und Unterstützungsbedarfe der brandenburgischen Forschenden zu ermitteln. So können Angebote datenbasiert und zielgerichtet konzipiert werden. Zu diesem Zweck wurde eine quantitative Bedarfserhebung zum FDM unter den Forschenden der am Verbundprojekt beteiligten Hochschulen durchgeführt. Die Bedarfserhebung wurde als Online-Umfrage[2] in deutscher und englischer Fassung zur Verfügung gestellt. Insgesamt umfasste die Erhebung 32 Fragen zu den Themenbereichen Datenquellen/-arten, Datenspeicherung, Datenpublikation, Nachnutzung, Organisation der Forschungsdatenverwaltung, Schulungs-/Unterstützungsbedarfe sowie Kenntnisse zu rechtlichen und ethischen Aspekten im Umgang mit Forschungsdaten. Trotz stetig wachsender Anforderungen der Forschungsförderorganisationen, zeigen die Ergebnisse der Forschenden (N = 486) insgesamt einen eher niedrigen bis durchschnittlichen Kenntnisstand im professionellen Umgang mit Forschungsdaten. Als punktuelles Beispiel sind Datenmanagementpläne (DMP) ca. 55 % der Teilnehmenden unbekannt während 23 % der Teilnehmenden DMPs zwar kennen, aber nicht nutzen. 15 % der Teilnehmenden nutzen sie immer oder meistens zur Planung ihrer Forschungsvorhaben, weitere 7 % eher selten. Ein Viertel der Teilnehmenden hat bereits Forschungsdaten in einem digitalen Repositorium veröffentlicht; die Mehrheit hat dies jedoch (noch) nicht getan. Die Unterstützungsbedarfe der Forschenden sind vielfältig. Ein hoher Bedarf besteht vor allem an persönlicher Schulung und Beratung sowie technischer Unterstützung; als besonders wichtig wird Unterstützung u. a. in den Bereichen Datenpublikation/Open Access, Repositorien, Datenschutzrecht sowie Datendokumentation angesehen. Erste Schlussfolgerungen für die auf den Daten basierenden FDM-Maßnahmen für Brandenburg unterstützen die Etablierung zweier technischer Dienste: Das Tool RDMO (Research Data Management Organiser)[3] zur systematischen Planung eines Forschungsvorhabens mithilfe von DMPs und das Forschungsdatenrepositorium RADAR (Research Data Repository)[4] zur Veröffentlichung und Archivierung von Forschungsdaten. Eine bedeutende Rolle werden diesbezüglich der Aufbau eines zu verstetigenden, brandenburgweiten Helpdesks und regelmäßige Schulungsangebote spielen. Wichtige Bausteine solcher Schulungsangebote müssen u. a. Workflows zur Dokumentation, die Verwendung von Repositorien und das Thema Datenschutz sein. Weitere FDM-Maßnahmen werden aktuell anhand der in der Auswertung befindlichen Daten erarbeitet. Vorausblickend werden hierzu ebenfalls hochschul- und disziplinspezifische Aspekte beleuchtet, um möglichst passgenaue FDM-Unterstützungsangebote in Brandenburg aufzubauen.

TM was carried out in a nitrogen atmosphere at 200 °C for 4 hours. For FU, a solution of 85% furfuryl alcohol, 10% water and 5% tartaric acid was used, which was impregnated in a vacuum pressure process, followed by polymerization at 120 °C for 16 hours. For each wood species, one test group was left as an untreated reference, the other groups were treated according to the treatment types TM, FU and TF. Per group 10 samples were tested using experimental modal analysis. Due to the orthotropy of the wood, the acoustic parameters dynamic modulus of elasticity (E), damping and sound radiation coefficient were determined in both the longitudinal and radial directions. The results show that TM slightly decreases longitudinal E for all three species and slightly increases radial E for maple and hornbeam. FU and TF strongly increase the E in the radial direction, especially for maple and alder. For all three species the damping is reduced by TM, more in the radial direction than in the longitudinal direction. FU and TF increase the damping in the longitudinal direction, mainly for maple and alder, but also reduce it in the radial direction. The sound radiation coefficient is reduced by FU and TF for all three species, particularly in the longitudinal direction. However, in both the longitudinal and radial directions, TM slightly increases the sound radiation coefficient for all three species. The anisotropy ratio of the longitudinal/radial E of all three species is reduced by FU and TF, whereas TM has no significant effect on it.

In RISE-DE ist das „Handlungsfeld 9 Leistungsmessung“ zwar angedacht, aber ohne eine weitere Darstellung, wie diese Evaluation in der Praxis durchgeführt werden könnte. Dieses Defizit soll nun durch einen konkreten Vorschlag zur Vorgehensweise ausgeglichen werden. Nach einer Einordnung von Evaluationen im Rahmen einer Theorie zum Management, wird darauf eingegangen, dass eine Leistungsmessung im öffentlichen Dienst andere Kriterien als in Wirtschaftsunternehmen erfordert, da keine Gewinnmaximierung im Mittelpunkt steht. Der Fokus der Evaluation wird eher darauf gelegt, dass öffentliche Leistungen möglichst wirtschaftlich, effizient und wirkungsvoll erbracht werden. Orientiert an der „Handreichung zur Entwicklung von Methoden für die Evaluation von Anpassungsstrategien“ von Kaiser und Kind (2019) zur Evaluation einer Strategie wird eine Vorgehensweise vorgestellt und anhand der Forschungsdatenstrategie der HNEE am Thema Schulungen beispielhaft erläutert. Die betrachtete Forschungsdatenstrategie wurde 2023 im Rahmen der Landesinitiative Forschungsdatenmanagement in Brandenburg (FDM-BB) erstellt. Durch die Darstellung wird deutlich gemacht, dass die Anwendung der vorgestellten Methode konkrete Erkenntnisse, insbesondere durch Einbeziehung einer Umfeldanalyse und unabhängig der relativ kurzen Laufzeit der Strategie, ermöglicht. Die vorgeschlagene Methode zur Evaluation ließe sich durch leichte Modifikationen bei den Evaluationsfragen und Bewertungsrubriken auch auf Forschungsdatenstrategien, die nicht mit RISE-DE erstellt wurden, anwenden.

Holzanatomisches Kolloquium N2 - Das DFG-Forschungsprojekt „Vorhersagbarkeit der Farbänderungen von Holz im Innenbereich - Die Auswertung in Abhängigkeit von der Strahlungsdosis als neuer Ansatz“ beschäftigt sich mit den Farbveränderungen der Oberflächen von in Mitteleuropa wachsenden Holzarten. Die optischen Eigenschaften des Holzes sind sehr unterschiedlich und im Wesentlichen abhängig von den im Holz vorhandenen chromophoren funktionellen Gruppen (z.B. phenolische Hydroxylgruppen, Doppelbindungen, Carbonylgruppen) und chromophoren Systemen (Chinone, Chinomethide, Biphenyle) (Hon 2001; Rowell et al. 2012). Sowohl zwischen verschiedenen Arten als auch innerhalb einer Holzart gibt es zum Teil erhebliche Farbschwankungen. Eine veränderte Lichtbrechung durch Strukturmerkmale wie Dreh- und Wechseldrehwuchs hat auch Einfluss auf das optische Erscheinungsbild. Farbänderungen treten bereits beim Trocknen oder Dämpfen der Hölzer auf (Aydin und Colakoglu 2005). Zudem verändert sich die Farbe der Oberfläche sowohl beim Auftragen von transparenten Oberflächenbeschichtungen („Anfeuerung des Holzes“) und durch Kombination von beidem. Licht ist der sichtbare (englisch: visible (Vis)) Teil des elektromagnetischen Spektrums, neben weiteren Spektralbereichen wie ultravioletter (UV) und infraroter (IR) Strahlung. UV-, VIS- und IR-Strahlung haben als Teile des Sonnenstrahlungsspektrums eine energetische Wirkung auf Holzoberflächen. Die Farbänderungen bei natürlicher Alterung werden durch Strahlung von UV-, VIS- und IR-Licht und der dadurch induzierten Photooxidation hervorgerufen (Hon und Chang 1982; Feist und Hon 1984; Hon und Minemura 2001). Zur optischen und chemischen Erfassung der Veränderungen der Holzoberflächen wurden in dem Projekt u.a. Farbmessungen im CIE L*a*b*-Farbraum (DIN EN ISO/CIE 11664-4:2020-03), abgeschwächte Totalreflexions-Fourier-Transformations-Infrarot-Spektroskopie (ATR-FTIR) und Spektroskopie im ultraviolett-visuellen Bereich (UV-Vis)sowie regelmäßige Farbscans der Probenoberflächen durchgeführt. Zudem wurden die Methoden der Gaschromatographie mit Massenspektrometrie-Kopplung (GC- MS) und die zelluläre UV-Mikrospektralphotometrie (UMSP) angewandt. Letzte wird im Folgenden näher erläutert. Koch 2004 führte umfangreiche, topochemische Untersuchungen über Inhaltsstoffe im Holzgewebe und deren Bedeutung für die Holzverfärbung durch. Die grundlegenden Untersuchungen zur fakultativen (an Fagus sylvatica L.) und obligatorischen (an Prunus serotina Borkh.)Farbkernbildung beinhaltete die UMSP-Methode. Damit können aromatische Verbindungen in einzelnen Zelltypen und Zellwandschichten hochauflösend, topochemisch detektiert werden. Zudem ist eine qualitative Charakterisierung bzw. Reaktionen von Inhaltsstoffen über UV-Spektren vor und nach einer Sonnenlicht-Simulation möglich. Mit Hilfe der zellulären UV-Mikrospektralphotometrie können aromatische Verbindungen (Lignin, phenolische Extraktstoffe) in einzelnen Zellwandschichten bei einer Auflösung von 0,25 μm x 0,25 μm lokalisiert werden. Die qualitative Charakterisierung von Inhaltsstoffen erfolgt über die Aufnahme von UV/Vis- Spektren im Wellenlängenbereich von 240 bis 700 nm (Messbereich für das UMSP 80, siehe Kapitel 2). Durch das spektroskopische Flächen-Scanning können die Verteilung und semi-quantitative Konzentration von Lignin und phenolischen Extraktstoffen graphisch dargestellt werden (Koch et al. 2003, Koch und Kleist 2001). Vor allem die genaue Visualisierung der farbgebenden Komponenten in den unterschiedlichen Zelltypen und Zellwandschichten sowie deren Änderung durch die Sonnenlicht-Exposition liefert weitere grundlegende Erkenntnisse über die photochemischen Reaktionen im Holzgewebe. Für die chemische Charakterisierung der Stoffe können zudem Punktmessungen mit einer Auflösung von 1 μm² durchgeführt werden. Diese UV/Vis-Extinktionsspektren werden in einem Wellenlängenbereich von 240 bis 580 nm aufgenommen. Ein Absorptionsmaximum im Wellenlängenbereich von 276 bis 280 nm ist z.B. typisch für aromatische und konjugierte Verbindungen. Nach Koch 2004 entstehen mit zunehmender Trocknungstemperatur höherkondensierte Verbindungen, die durch eine starke Verschiebung der Absorptionsmaxima in den längerwelligen Spektralbereich und insgesamt höheren Absorptionswerten charakterisiert werden. Diese Reaktionsmechanismen erklären auch das Farbverhalten des Holzes bei längerer Lichteinstrahlung, durch die ein intensives Nachdunkeln (Lichtalterung) einsetzt. Aufgrund der erheblichen Datensätze von bis zu 60.000 Messpunkten für jedes Scanning-Feld (Größe ca. 50 μm x 50 μm) wird die Auswertung der topochemischen Analysen im Gesamtvorhaben exemplarisch auf drei Holzarten und zwei Schnitttiefen mit vier Messzeitpunkten pro Setup und Behandlung (unbehandelt/extrahiert) reduziert. Die UMSP-Methode findet seither in vielen Bereichen der Holzanalytik Anwendung, z.B. in der Holzbiologie und in der Holzchemie (Andersons et al. 2016, Biziks et al. 2020, Ehmcke et al. 2020, Lewandrowski et al. 2022, Rüggeberg et al. 2008, Schmitt et al., 2015, etc.) KW - Holz KW - Bestrahlung KW - UMSP KW - Alterung KW - Farbänderung Y1 - 2024 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:kobv:eb1-opus-8921 SP - 122 EP - 130 CY - Dresden ER - TY - CHAP ED - Spies, Michael ED - Alff, Henryk ED - Raab, Christoph ED - Zakirova, Aksana ED - Zuberi, Mehwish T1 - Sustainable Food and Biomass Futures? Localised Approaches to Agricultural Change and Bioeconomy N2 - In recent decades, the global demand for food and biomass has been increasing, while natural resources continue to deplete and are further stressed by the impacts of climate change. Additionally, rising energy and input costs have pushed agricultural production to its limits, placing farming communities in an increasingly precarious position. This volume presents a collection of papers that challenge us to reconsider existing agri-food and farming systems from a local perspective, and to explore alternative, more sustainable production approaches. The volume is structured around four key themes. The first theme scrutinizes agricultural modernization, with a particular focus on technological innovations and monoculture-based agricultural production. The second theme centres on the political-economic dynamics and local challenges. The third theme assesses participatory methods for knowledge production on processes of agrarian change across various regional settings. Finally, the fourth theme explores alternative production systems that are socially and ecologically sustainable, offering potential solutions for reshaping agricultural systems under pressure.

T1 - Seasonal prevalence of Nosema maddoxi infection in Halyomorpha halys, an invasive pest of hazelnut orchards in Georgia T2 - Acta Horticulturae N2 - The prevalence of the microsporidium Nosema maddoxi in populations of brown marmorated stink bug (Halyomorpha halys) from three sites in Guria and eight sites in Samegrelo, Georgia is described. Investigations were conducted on adults collected in fall and spring from fall 2020 to spring 2022. The prevalence of infection differed by both region and season. Total prevalence of N. maddoxi in adults from the Guria region was significantly higher than the Samegrelo region. Infection levels in fall were higher than in the spring in the Guria region, but inconsistent over seasons in the Samegrelo region. Infection levels did not differ by sex. We hypothesize that higher population densities and more adult aggregation in Guria compared with Samegrelo helps to explain the higher infection levels in Guria.

One of the most important is to build up a connection to researchers and bridge the gap between research data infrastructure and researchers. Different scientific communities have different requirements for research data management and expectations regarding text and data publication. In many of the sub-disciplines of engineering sciences, research data management practices are not established so far. When it comes to contact between data stewards and researchers, a common knowledge base has to be established to become clear about why and what actions for research data management has to take, that engineering researchers can adapt them for their research data management practices. Many research data management standards have to take into consideration. However, to this point of time, the research data management community lacks for data literacy graphics to explain how the technical data management ecosystem works together with standards like the findability, accessibility, interoperability and reuse (FAIR) principles. Therefore, we developed a graphic for data literacy and consulting scenarios.

The MAA requires projects 1. to build on the activities of partners with complementary types of knowledge, including in particular (representatives of) the targeted users of the project results; and 2. to ensure the joint engagement of these diverse partners in all phases of the innovation process. Projects that are required to comply with the MAA are officially called ‘Multi-Actor projects’. They include some international research and innovation projects funded under the EC’s Framework Programme for Research and Technological Development Horizon Europe (or its predecessor Horizon 2020), as well as local EIP Agri Operational Groups (OGs), which are co-funded by the EC and the Member States (MS). As with all public policies, several groups of actors – including the EC itself – have a legitimate interest in learning how well the MAA is being implemented by its intended target actors. A general answer to this question is complicated by the fact that Multi-Actor projects differ in many respects, such as the innovative objectives they pursue, the size and composition of their consortia, the duration of their activity, and their geographic scope. One aspect that makes it particularly difficult to identify general implementation determinants is their embeddedness in distinct multi-level governance settings. For example, while Horizon Europe-funded research project consortia operate under the direct management of the EC’s agencies, OGs are funded under a measure which is formulated by the EC but implemented at the national, or in some MS, regional level. These differences inevitably have an impact on how success in the implementation of the MAA can be achieved. In this paper, we propose a framework for analysing the factors that determine success in the implementation of the MAA, as well as their interrelations. This framework builds on a review and integration of insights from various fields of social scientific research, notably research on public policy implementation, multi-level governance, and participatory approaches in agricultural policy. To test the framework, we apply it to data from four case studies of OGs that we conducted in 2020 in the frame of the H2020-funded research project LIAISON.

Extensive cattle grazing systems linked to biodiverse grassland meet consumer demands for animal welfare and provide a number of ecosystem services. In the Federal State of Brandenburg, suckler cow husbandry is of particular importance due to the low yielding soils and the high proportion of grassland areas. Grazing of lower quality grassland with cattle can increase biodiversity and preserve the cultural landscape. Since the offspring of suckler cows is mostly sold to supra-regional fattening farms, the valorisation of grassland has yet to take place within the region. The reasons for the transfer of added value are manifold and range from a lack of regional structures for slaughtering, processing and logistics to a lack of market opportunities and low profit margins. In order to increase the regional added value of beef from pasture-based farming, business models need to be developed that distribute risks and benefits along the value chain, and correspond to consumers who are willing to contribute to sustainability efforts. Using the approach of a living lab, the R+D project ""WertWeideVerbund"" aims to develop and test models of cooperation and coordination between stakeholders in the beef value chain in Brandenburg. The present paper aims to illustrate the basic requirements and expectations of the different stakeholder groups along the value chain of beef for the development of regional value-based cooperation. Interviews and focus groups with farmers, slaughtering, processing, potential bulk purchasers (canteen kitchens, food retailers and butchers) and interest groups (farmers, landscape conservation) will be conducted by August 2021. Furthermore, a panel study with 1000 participants will identify consumers’ priorities for beef consumption. Preliminary results show that, in addition to organisational-legal requirements, the definition of a common value basis is of particular importance for the development of cooperation. For this purpose, the stakeholders along the value chain defined minimum requirements as well as requirements for a premium quality standard for high animal welfare husbandry of cattle. The discussed quality requirements include aspects such as suckler cow husbandry, minimum grazing period (at least during the vegetation period), fattening (e.g. dry bedding options, outdoor access) and feeding (minimum share of farm-produced feed, GMO, origin of soya-based feed, etc.). With regard to animal welfare, other relevant criteria involve animal health (use of antibiotics), transport time and stress-free slaughtering. Furthermore, aspects such as transparency along the value chain (regionality), participation in a quality assurance system (e.g. Participatory Guarantee Systems, animal welfare officers) and fair remuneration of the producers are also considered as basic prerequisites in order to successfully establish a value- based cooperation Starting in September 2021, potential business models, based on the discussed quality requirements, will be developed in cooperation with interested stakeholders and tested and evaluated in an iterative process.

Besides natural pedogenetic processes, on agricultural land, soil acidification is amplified by the removal of the harvested biomass as well as by the application of acidifying fertilizers. Therefore, regular lime application on agricultural fields is inevitable to sustain soil quality and productivity. In Germany, the standard method for defining the lime requirement of a soil is the VDLUFA framework of the German Advisory Board for Agricultural Analytics. The VDLUFA method uses look-up tables that define the lime requirement according to soil texture, soil pH (CaCl2) and soil organic matter (SOM) content (LVLF et al., 2008). To determine these lime-relevant parameters, fields should be subdivided into subunits of 3 to 5 ha. Within a subunit, one mixed sample from 15 to 20 samples should form a composite sample for further reference lab analysis. However, a uniform lime requirement determined for subunits of 3 to 5 ha is often in contrast to the real soil variability observed in the field (Kling et al., 2019). In order to reflect the within-field soil variability, a few studies have demonstrated the use of high-resolution proximal soil sensing (PSS) data as tools for variable rate (VR) lime application (Bönecke et al., 2020; Pätzold et al., 2020). However, there is a lack of studies that evaluate the feasibility and benefit of VR methods in on-farm field trails. Therefore, the aim of this study is to compare the performance of site-specific liming based on PSS to optimize soil pH and crop yield with that of commonly applied standard liming methods in Germany. To determine the effect and practicability of the VRA method, a multi-site-multi-year experiment was conducted between 2017 and 2020 on three sites in Brandenburg, Germany. The trial compared the effects on soil pH and crop yield of three lime management practices: variable-rate liming based on PSS data (VR-PS), uniform liming rate based on the VDLUFA standard method (UR), and no liming (ZR). Soil texture and soil pH were assessed with two mobile sensor platforms: the Geophilus system measuring apparent electrical resistivity (ERa) and Gamma-radiation and the Veris pH Manager (Veris Technologies Inc., Salina, KS, USA). Crop yields were obtained from revenue recordings of combine harvesters. Lime prescription maps were generated with an adapted and stepless VDLUFA algorithm, allowing a continuous CaO recommendation (Bönecke et al., 2020). Based on these maps, management zones were delineated to perform lime spreading with state-of-the-art technique. In this study, we outline the conceptual framework of the VR liming approach and present first results from the on-farm field trials to verify the VR approach for an optimized soil acidity management as well as consider whether the higher economic revenue can compensate for added costs for mapping services and spreading technologies.

Proximal and remote sensors measuring different physical properties of plant tissue, as surrogates for nutritional and health status are being developed in response to the ever-increasing need of quick and reliable crop monitoring for precision agriculture. A recently developed fluorescent-based device, Multiplex, is of particular interest for high spatial resolution modeling and managing systems, given its capacity of measuring fluorescence properties of chlorophyll and other pigments at both leaf and canopy levels, and both in discrete (“one-shot”) and continuous (“on-the-go”) measuring modes. The goal of this research was to assess the ability of Multiplex to measure nitrogen (N) content of different crops and compare it with the performance of other well-established sensors. Several fields with spring and winter barley and corn at three locations in Brandenburg representing different levels of N fertilization were chosen for the measurements. Leaf N content (% weight) from plant samples was compared to measurements of: Fluorescence (Multiplex Research sensor), light transmittance (SPAD sensor), and reflectance (ASD Field Spectrometer). Additionally, direct canopy fluorescence (Multiplex Research sensor) was compared to canopy reflectance (ASD Field Spectrometer), light transmittance of leaf composites (SPAD sensor) and remote reflectance from multispectral sensors on remotely piloted aircrafts (RPA) or drones. Out of the 25 variables Multiplex produces at each reading, the Chlorophyll Index, the Flavonoid Index and the Nitrogen Balance Index showed the closest relationships to N. All these variables contain infrared and red fluorescence components suggesting that these have a key role in chlorophyll and N determination. In general, however, SPAD showed higher accuracy than fluorescence as a predictor of N content in leaves. Despite of this, Multiplex seems particularly convenient for fast on-field assessment of crop canopy status. At the canopy level, drone-based sensors can be as accurate as Multiplex to assess the N status of the crops under study. In the case of Multiplex, however, since the device reads are taken below the canopy and parallel to the ground, measurements are not affected by canopy density and soil background, which can be an inconvenience for vertical reflectance measurements as provided by drones and spectrometers.

The ecological challenges for agrarian sectors are further complicated by social factors such as growing world population and an expanding demand for biomass-based products. Formalized knowledge structures can benefit from approaches that consolidate informal local knowledge networks in understanding social and ecological change related causal chains (Tengö et al., 2013). This is especially relevant for the research-policy interface concerning sustainable agrarian system management. As part of the junior research group TRANSECT, which investigates the social-ecological effects and interdependencies of agrarian transformations in Central and South Asia, a framework for knowledge mapping on sustainable land use systems is under development. We aim to bring together knowledge from local land users and other relevant stakeholders to develop future policy scenarios related to bio-based economy in the agrarian sector and to critically assess their social and ecological consequences on the ground. Our proposed framework is inspired by previous experiences with the MARISCO method (Ibisch and Hobson, 2014; www.marisco.training), a methodology for the adaptive management of risk and vulnerability, developed at the Center for Econics and Ecosystem Management in the Eberswalde University for Sustainable Development. This approach has been applied in various projects of natural resource management as a tool that allows the collection of complex and diffused knowledge from different sources, and to structure, evaluate, and prepare for the development of integrated solutions. The visual presentation of existing knowledge in the form of ‘knowledge maps’ that raise awareness of ignorance, and the systemic identification of knowledge gaps and risks are central features of MARISCO method (Ibisch and Hobson, 2014). While the original methodology provides an established and proven toolbox for evaluating the ecological dimension of complex socio-environmental challenges, our inspired methodology elaborates on the social dimension of environmental and societal threats as well as policy interventions, for which we find it crucial to put a stronger emphasis on equity. In contrast to the more ecosystem-focused MARISCO method, a central feature of our approach is a socially differentiated analysis that distinguishes between different social groups or strata when evaluating social (and ecosystem) services and the (social) impact of stresses or threats. We will introduce and elaborate on our proposed participatory and socially differentiated approach for knowledge mapping on sustainable land use systems with illustrative examples from experiences in Central Asia. As our current experience shows, a key challenge in designing and implementing such approaches is to take social-ecological complexity seriously while keeping the method manageable for regular workshop settings without overburdening participants.

After jointly formulating ten core statements as their own practical principles for managing healthy farming systems, they went on to develop a training strategy to transfer this knowledge about promoting health on organic farms, describing a co-learning concept to collaborate with their peers in a long-term process. Most suitable, appropriate methods and optimal conditions were discussed for successfully spreading such complex tacit knowledge among other farmers, and crucially, for invoking change in behavior. One core concept emerged as being most critical for success – inspiration. It was the group members’ or peers’ ability to inspire, which, in their experience, was key to stimulate their own change of practices, motivate trials with new methods, or adopt a new perspective or philosophy for managing their farm. They described that it was not only the reading about different techniques, or seeing new machinery in action during a farmer field day – the actual spark that triggered their own action was in most cases personal interaction. The personal exchange and inspiration among peers, who have established a sound level of trust, who share their experiences, as well as passions and failures seemed to be most likely the key element of farmer learning. This was particularly true for learning and enhancing soft skills, such as intuition, gut-feeling or self-reflection – all essential skills for running healthy organic farms according to the farmer group. The farmers of this project series have attributed great value to learning with and from each other during a co-learning process, in particular when the group is regularly stimulated by and collaborating with interdisciplinary researchers who are embedded in this co-learning process. We could therefore conclude that not only participatory-/action research or multi-actor approaches, but agricultural research in general benefits from a deep connection and understanding between researchers and farmers, to successfully inspire change in practices, and the adoption of new philosophies and perspectives that trigger long lasting transformation.

The implementation of new strategies in nutrient management on organic farms is such a complex challenge due to regional differences in perception and soil resources as well as individual prerequisites on farms. The project “NutriNet: competence- and co-research network for development of nutrient management in organic farming” meets this challenge by building a living lab according to Dell’Erra & Landoni (2014) and Rose et al. (2018) and aims i) to derive region-specific nutrient management advice for organic farms from scientific findings in field trials (nutrient management research), ii) to ensure implementation of these advice through group motivation and enable an exchange of expert knowledge in Field Schools (transformative research), iii) as well as to evaluate key methods, roles, competences and resources for an implementation-oriented co-research process (process research). Sixty farmers organized in six regions in Germany build the basis of the “NutriNet” living lab, each accompanied by a regional consultant and a group of scientists on a joint level. All actors are involved in the co-research process to varying degrees depending on the stage of the process and can take on different roles. Process steps are ideation, development of the experimental question and design, trial implementation, data analysis, interpretation of data and implementation and transfer of results. The living lab character is especially addressed in the structure of the co-research process for conducting field trials in the “NutriNet” project as it describes a learning system within the system. The co-research concept allows to take different experimental designs into account, namely field trials with a demonstrative character that provide methodological skills for farmers and pre-test results as well as field trials with spatial and temporal repetitions that meet scientific requirements. In order to reduce the scientific framework conditions to such an extent that, on the one hand, scientifically valid results and, on the other hand, the highest possible feasibility of the experiments by the farmers can be guaranteed, so-called regional and network trials are being tested in NutriNet. The concept is based on taking randomization and spatial repetition into account by repeatedly setting up the trial at several locations. In order to take environmental influences (soil, climate) into account, the possible sites are divided into groups according to site characteristics by using a cluster analysis. By involving not only one but many farmers throughout the whole co-research process and enabling exchange among them in Field-Schools, methodological training and implementation of findings are addressed as a part of the research. After one year of field trials two regional trials with ten and seven farmers were set up as well as one network trial on thirteen farms in four regions. Methodological evaluation of the process led to adjustments in experimental design, data collection and coordination between experts that are implemented in a new series of network trials starting in autumn 2021.

Responding to this, and to the growing severity of global threats to agricultural and food systems, national and international research funders are increasingly demanding that funded projects achieve real-world transformation of farming systems towards true sustainability and resilience. This development is not only a new funding opportunity for researchers. Because separating the roles of knowledge generation and knowledge exchange with practice will often fail to achieve the necessary transformation, (at least some) researchers will need to engage in this transdisciplinary process of transformative agricultural research. As a consequence, the roles of these researchers need to shift towards stronger integration in farming practice, and deeper exchange with practitioners, adding a new key role to teaching and research. We argue that meeting the goals of the mission of transformative research in agriculture requires three essential freedoms. First, researchers need to be free to engage in this transformative research. This entails a freed mindset, which enables researchers to leave behind traditional roles, e.g. for true knowledge exchange, co-design of projects, and learning from farmers. In addition, there needs to be a stronger appreciation for transdisciplinary and transformative research in the research community, accompanied by a reduced pressure to perform in other currently dominating assessment categories. Second, farmers need to be free to engage in this process as well. Again, this requires an open mindset, e.g. to engage in, and learn from collaborative research, but also available funds and time to engage in the process. Third, transformative agricultural research needs freedom in the project structure and in administrative rules. This includes the permission to fail and to tolerate errors, so that the people involved in the process are able to learn from mistakes. In addition, this is required so that projects are not set up to avoid risks, and can really be transformative and contain innovative elements. Finally, funders will need to show trust in the parties and to reduce administrative burden. Within this framework we discuss the success factors and limitations of transformative agricultural research using examples from various recent national and international projects.

The findings from ProAkis (2015) show that different types of organisations such as administrative offices, public or semi-public advisory services, rural academies/universities, producer organisations, other NGOs or private consultants engaged in the Agricultural Knowledge and Innovation System (AKIS) can act as ISS. The funding of ISS can be public, private or a mix of both. A first literature review indicates that studies often focus on the larger “enabling environment” and the structure of the Agricultural Knowledge and Innovation Systems (AKIS). Moreover, many authors pay particular attention to the role of public or semi-public advisory organisations (Knierim et al., 2015; Sulaiman 2015). The aim of this paper is to assess the different types of organisations that provide support for interactive innovation, and to analyse the particular role of each type of organisation for interactive innovation projects. Particular attention will be payed to the divers group of organisations that are not part of a (semi)-public advisory organisation. The paper is based on the analysis of more than 200 case studies of publically or privately funded interactive innovation projects within the EU and beyond. The selection of cases took place under the framework of the project LIAISON funding by the EU research and innovation programme Horizon 2020 (grant agreement No 773418). European and national databases contain several thousands of projects in agriculture, forestry and rural development. We selected projects applying the interactive innovation approach from a) EU programmes (EIP-Agri, Horizon2020, Interreg, and LIFE+); b) nationally/regionally or privately funded projects; and c) informal initiatives or networks in the agri-food, forestry, bioeconomy or nature conservation area. Preliminary results indicate that publically funded IIS play a core role for legal/administrative compliance of projects. Semi-public advisory services take up this role as well, and they are strong in linking farmers with scientists, technicians, entrepreneurs etc. However, they often exist and offer efficient ISS only for those industries that have a long tradition for a sector or area (e.g. dairy, pork, poultry or club fruit). Niche sectors or industries with little policy engagement often lack the support of a publically funded advisory service but profit more from producer organisations or rural academies/universities when they take up the role of ISS.

The issue is important because evaluation in terms of irradiance has not been studied in more detail. Irradiation intensities were reported in many studies but tended to have metadata status. The concrete influence of the irradiance on chemical and colour changes in the wood remains open. This paper presents an approach to inquiry-based teaching within a basic research project. Initial results from a large-scale data series are presented here. Irradiance is the term for the total power of incoming electromagnetic energy striking a surface, related to the size of the area, measured in watts per square metre [W/m²].

Im Sinne einer offenen Lehrwerkstatt ist das Modul interdisziplinär ausgerichtet und für Bachelor- und Masterstudierende verschiedener Studiengänge anwählbar. Die studentischen Tutor:innen werden von zwei Professoren der Hochschule begleitet. Angeschlossen an das Modul ist neben Vorträgen und Exkursionen die Forschung im Reallabor „Ackerbaum“ wodurch transdisziplinäres Arbeiten vermittelt wird. Dabei handelt es sich um eine knapp 10 Hektar große Ackerfläche im Löwenberger Land, nördlich von Berlin. Auf dem die Studierenden sowohl Bäume pflanzen, als auch deren Wachstum und ihre Effekte auf das Mikroklima und die Ackerkulturen, sowie den Boden beobachten und dokumentieren. Wissenschaftliche Unterstützung erhält das Projekt durch Wissenschaftler:innen der Universität Bonn und dem ZALF e.V., die gemeinsam im „Agrarsysteme der Zukunft-Projekt – DAKIS“ (https://adz- dakis.com/ueber-dakis/) daran arbeiten, die Auswirkungen von Agroforstsystemen auf Ökosystemleistungen und Biodiversität zu erfassen und zu bewerten. In den vergangenen 4 Jahren 2017 – 2021 wurden von den Studierenden über 50 Projektberichte erstellt. Diese wurden aufwändig analysiert und mittels vorher definierter Indikatoren klassifiziert. Um weitere Rückschlüsse auf die Qualität der studentischen Lehre ziehen zu können, wurde in Umfragen die Meinung und Zufriedenheit der Studierenden als auch der Tutor:innen anonym abgefragt und ausgewertet. Die Daten werden aktuell ausgewertet und die Analyse kann auf der Tagung vorgestellt werden. Y1 - 2022 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:kobv:eb1-opus-6736 N1 - Tagung, 2.-3.

Jahrestagung 2022 der Deutschen Gesellschaft für Limnologie e.V. N2 - Aufgrund von Corona-bedingten Einschränkungen fand die Methode der VR-Tour als Ersatz für Exkursionen in den vergangenen Semestern an der Hochschule für Nachhaltige Entwicklung Eberswalde (HNEE) Anklang, sodass diese Methode nun auch weiterhin genutzt wird. Studierende des Moduls „Feuchtgebietsmanagement“ (Masterstudiengang Nachhaltige Regionalentwicklung - Management - Naturschutz) erarbeiten im Sommersemester 2022 nach der Methode „Forschendes Lernen“ eine VR-Tour als digitales Format für die Hochschullehre sowie die Wissenschaftskommunikation. Die Tour widmet sich den Feldsöllen: Die Kleingewässer mit einer Größe von < 1 ha sind und können ein wichtiger Lebensraum für seltene Arten in einer gleichförmigen Agrarlandschaft sein. Ihr Zustand wirkt sich maßgeblich auf Flora und Fauna in und um Feldsölle aus. Dieser hängt von neben natürlichen auch von anthropogenen Faktoren wie umliegender und direkter Nutzung ab. Um eine erhöhte Sensibilisierung für Feldsölle als naturschutzfachlich relevante Lebensräume zu erreichen, spielt die Wissenschaftskommunikation eine wichtige Rolle, die mit der VR-Tour mit Einsatz von u.a. 360-GradAufnahmen als Darstellungsmöglichkeit umgesetzt werden soll. Nutzer des Formates können eine Art virtuellen Spaziergang unternehmen, in dem sie selbstständig Feldsölle als Biotope und Trittsteine im Biotopverbund in der Agrarlandschaft erkunden können.

N2 - Digitale Wissenschaftskommunikation - Die Lebenswelt des Fischotters als interaktives Storyboard: Im dritten Online-Semester sind infolge der Corona-bedingten Einschränkungen Geländeübungen und Exkursionen an den Hochschulen kaum noch möglich. Nachdem im Sommersemester 2020 im Rahmen der Online-Lehre ein erster Ersatz mittels Virtueller Exkursionen im seminaristischem Unterricht durchgeführt wurde, wird im Sommersemester 2021 an der Hochschule für Nachhaltige Entwicklung Eberswalde eine Virtuelle Geländeübung als digitales Lehr- und Lernmodul entwickelt. Gemäß der Prozeßmethode des Forschenden Lernens erarbeiten die Teilnehmer des Moduls Fließgewässer- und Feuchtgebietsmanagement (Masterstudiengang Regionalentwicklung und Naturschutz*) eine digitale Darstellung komplexer ökologischer Zusammenhänge anhand der Interaktion des Fischotters mit seinem Habitat. Dazu wird ein interaktives Storyboard u. a. unter Einsatz von 360° Technik und Augmented-Reality-Elementen erstellt. Ziel ist der Einsatz des neuen Formates in der Hochschullehre, aber auch in der allgemeinen Wissenschaftskommunikation.

GIL-Jahrestagung, Künstliche Intelligenz in der Agrar- und Ernährungswirtschaft N2 - Extensively used grasslands (meadows and pastures) are ecologically valuable areas in the agricultural landscape and part of the multifunctional agriculture. In Germany, the quality of these grasslands is assessed based on the occurrence of certain plant species known as indicator or character species, with indicators being defined at regional level. Therefore, the recognition of these indicators on a spatial level is a prerequisite for monitoring grassland biodiversity. The identification of indicator species for the status quo of grassland using traditional methods was found to be challenging and tedious. Deep learning-algorithms applied to high-resolution UAV imagery could be the key solution, where UAV with remote sensors can map a large area of grassland in comparison to manual or ground mapping methods and deep learning-algorithms can automate the detection process. In this research work, we use an EfficientDet based algorithm to train an object detection model capable of recognizing indicators on RGB data. The experimental results show that this approach is very promising in contrast to the difficult and time-consuming manual recognition methods. The model was trained with the momentum-SGD optimizer with a momentum value of 0.9 and a learning rate of 0.0001. The model was trained and tested on 1200 images and achieves 45.7 AP (and 85.7 AP50) on test data set. The dataset includes images of four distinct indicator plant species: Armeria maritima, Campanula patula, Cirsium oleraceum, and Daucus carota KW - digital agriculture; biodiversity in grassland; HNV farming; deep learning; object detection Y1 - 2022 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:kobv:eb1-opus-6656 SN - 978-3-88579-711-1 SN - 1617-5468 SP - 57 EP - 62 PB - Gesellschaft für Informatik e.V.

Neben klassischen ertragskundlichen Aufnahmen wurde sich hauptsächlich auf die Entnahme von Bohrkernen an 15 Baumindividuen pro Probefläche und deren Auswertung konzentriert. Durch die Vermessung der Bohrkerne konnten Zeitreihen der Jahrringbreite (JRB) und nachfolgend des Jahrringindex (JRI) berechnet werden. Während für das Hauptfraßjahr 2003 alle vier Probeflächen mit einer ähnlichen Zuwachsreduktion reagierten, ergaben sich für das Folgejahr deutliche Unterschiede zwischen den geschädigten Flächen und der Referenz. Letztere erholte sich bereits wieder und wies einen JRI von 1,06 auf. Die geschädigten Flächen waren hingegen in ihrem Zuwachs noch stärker eingebrochen, was in einem JRI zwischen 0,20 (D60) und 0,30 (D40) bzw. 0,33 (D85) resultierte. Die folgende Berechnung von Resilienzkomponenten nach Lloret et al. (2011) verdeutlichte ebenfalls die Abhängigkeit zwischen Zuwachs und Entnadelungsgrad. Insbesondere die Recovery weist in diesem Zu- sammenhang darauf hin, dass durch die Freistellung der überlebenden Individuen und aufgrund gewisser Düngungseffekte nach dem Fraß ein Zuwachsniveau erreicht wurde, welches über dem der vierjährigen Periode vor dem Schadereignis liegt.

Thus data related to climate change and its site specific drought effects on one hand and current soil nutrient status on the other is especially required to support decision making. Besides soil texture, soil organic carbon is one of the most important key factors controlling soil nutrient status (eg. cation-exchange capacity) and soil water storage (e.g. field capacity) in the glacial deposits of north eastern lowlands. In contrast to soil texture, which can be considered as stable over periods relevant to practical forest management, for mapping soil organic carbon and its distribution throughout the soil profile a more dynamic regionalization approach considering contemporary measurements is needed. For this purpose, data on contemporary soil organic carbon stocks is taken from the second National Forest Soil Inventory and additional regional sampling points in Brandenburg (Germany). Potential covariates representing the soil forming factors: parent material, organisms (vegetation), age, relief and climate are obtained with high spatial resolution from forest site mapping, forest inventory, digital terrain analysis and climate models. The proposed regionalization approach captures the concepts of SCORPAN modelling and depth functions. While for estimation of carbon stocks in the entire soil solum stepwise regression analysis and geostatistical techniques are involved, the methodology to derive and map relative depth functions is based on cluster analysis and classification tree approach. The intended benefits by splitting regionalisation into plot level and relative vertical depth gradients are to ensure consistency of solum stocks and single soil depths and to avoid the construction of artificial depth gradients. Furthermore, the procedure allows a straightforward interpretation of covariates in the sense of pedogenetic processes, which: (a) supports variable selection and exclusion of spurious covariates during model development and (b) may provide direct decision support regarding environmental and management effects on soil organic carbon. The obtained statistical models contain covariates related to all five soil forming factors. But, the conducted analyses especially point towards high influences of depth to groundwater table and mean slope of catchment area on soil organic carbon storage. Invoking geostatistical techniques shows no remaining variation, to be explained by spatial position and thus don’t improve overall model performance. Cluster analysis of relative depth gradients results in five Clusters of acceptable heterogeneity. The highest differences between the clusters are observed across the portions of carbon stored in the forest floor. Relative depth gradients are especially distinguished by tree species composition and stand age.

Peatlands are important in terms of CO2 storage, water cycling, biochemical cycles, biodiversity, and ecosystem services. Peatlands are constantly altered and damaged due to agriculture and drainage. Thus it is crucial to manage them sustainably. How? First step – locating and quantifying them with geospatial data and remote sensing methods since locating and collecting data in field is highly expensive and arduous in terms of labour and time. Our MAIN RESEARCH QUESTION therefore is: Is it possible to generate a method to record the location of peatlands under forests at high resolution using RS?.

Mai 2020 (ONLINE), Vienna, Austria N2 - The destruction of habitats has not only reduced biological diversity but also affected essential ecosystem services of the Central European cultural landscape. Therefore, in the further development of the cultural landscape and in the management of natural resources, special importance must be attached to the habitat demands of species and the preservation of ecosystem services. The study of ecosystem services has extended its influence into spatial planning and landscape ecology, the integration of which can offer an opportunity to enhance the saliency, credibility, and legitimacy of landscape ecology in spatial planning issues. Objective: This paper proposes a methodology to detect red deer habitats for e.g. huntable game. The model is established on remote sensing based value-added information products, the derived landscape structure information and the use of spatially and temporally imprecise in-situ data (e.g. available hunting statistics). In order to realize this, four statistical model approaches were developed and their predictive performance assessed. Methods: Altogether, our results indicate that based on the data mentioned above, modeling of habitats is possible using a coherent statistical model approach. All four models showed an overall classification of > 60% and in the best case 71,4%. The models based on logistic regression using preference data derived from 5-year hunting statistics, which has been interpreted as habitat suitability. The landscape metrics (LSM) will be calculated on the basis of the Global Forest Change dataset (HANSEN et al. 2013b ). The interpolation of landcover data into landscape-level was made with the software FRAGSTAT and the moving window approach. Correlation analysis is used to identify relevant LSM serving as inputs; logistic regression was used to derive a final binary classifier for habitat suitability values. Three model variations with different sets of LSM are tested using the unstandardized regression coefficient. Results lead to an insight of the effect of each LSM but not on the strength of the effect. Furthermore, the predicted outcome is rather difficult to interpret as different units and scales for each LSM are used. Hence, we calculated the fourth model using the standardized regression coefficient. It harmonized the measurement units of the LSM and thus allowed a better comparison, interpretation, and evaluation.Conclusion: Our research reveals that applying a statistical model using coarse data is effective to identify potential red deer habitats in a significant qualitative manner. The presented approach can be analogously applied to other mammals if the relevant structural requirements and empirical habitat suitability data (e.g. home range, biotopes, and food resources) are known. The habitat preferences of red deer are best described by LSM concerning area-relation and wildlifeedge relations. Most important are edges between meadows, pastures or agricultural field and forest, as well as short paths between those elements for food resources. A large proportion of forest is important for species survival and positively influences the occurrence of red deer. Outcomes help to understand species habitat relation and on which scale wildlife perceives the landscape. In addition, they support the practical habitat management and thus the overall species diversity.

In den Jahren 1999 und 2000 wurde der Pilz als Maßnahme der biologischen Bekämpfung von L. dispar in Bulgarien freigesetzt. Seither hat sich E. maimaiga rasch auf der Balkanhalbinsel und in Südosteuropa ausgebreitet. Untersuchungen an zahlreichen blattfressenden Insekten bestätigten die hohe Wirtsspezifität. In einem Kooperationsprojekt wurde der Status von E. maimaiga in Bulgarien und Österreich untersucht. Achtzehn Jahre nach der Einbürgerung ist der Pilz in Bulgarien etabliert, und hohe Mortalitäten bei L. dispar werden seither regelmäßig dokumentiert. In Österreich wurde E. maimaiga in Screenings in den Jahren 2014 und 2018 in insgesamt 15 Eichenwäldern mit bekannten L. dispar-Vorkommen nicht nachgewiesen. Im Sommer 2019 wurden in zwei Eichenwäldern in Niederösterreich tote L. dispar Larven gefunden, die mit E. maimaiga infiziert waren.

Aquatische Stadien wurden mit einem Dipper oder einem Sieb, Adulte mit einem Aspirator, einem Kescher oder per Hand gefangen. Insgesamt konnten so 670 Mückenexemplare erhalten werden, die 14 Arten bzw. Artkomplexe aus den fünf Gattungen Aedes, Anopheles, Coquillettidia, Culex und Culiseta repräsentierten. 550 Individuen, die als Larven und Puppen gesammelt worden waren, gehörten vier Taxa an: Aedes annulipes-Gruppe, Ae. geniculatus, An. plumbeus und Culex pipiens-Komplex. Die 120 gefangenen Imagines wiesen eine wesent- lich höhere Artenvielfalt auf und setzten sich aus 14 Taxa in fünf Gattungen zusammen. Die meisten Exemplare gehörten zum Cx. pipiens-Komplex, wovon 116 Männchen morphologisch in Cx. pipiens und Cx. torrentium separiert werden konnten. Die Gattung Aedes war mit der höchsten Artenvielfalt vertreten (acht Taxa); die Gattungen Coquillettidia und Culiseta waren am seltensten (13 bzw. 5 Exemplare) und wurden nicht im aquatischen Stadium nachgewiesen. Friedhöfe zeigten die höchste Anzahl und Dichte von potenziellen Brutplätzen im urbanen Raum, wurden allerdings fast ausschließlich von Mücken des Cx. pipiens-Komplexes genutzt. Im Gegensatz dazu besaßen Wälder und Parks die höchste Artenvielfalt (acht bzw. neun Arten). Keine Stechmücken wurden auf landwirtschaftlichen Flächen gefunden. Ab Ende August sank die Anzahl der gesammelten aquatischen Exemplare deutlich ab. Während keine Neozoen, die als Überträger von Krankheitserregern gelten, in den Proben festzustellen waren, zeigt die Studie ein Artenspektrum an einheimischen Arten, das mögliche Vektoren enthält.

Preliminary Findings from the Project LIAISON T2 - 14th European Farming Systems Conference – Farming systems facing climate change and resources challenges (IFSA22), Évora, Portugal, 10-14 April 2022 (Session Session 1.6 - Institutions and organisations in interactive innovation, Part Theme 1 - Innovation Support Services) N2 - A large variety of organisations provides support for cooperative approaches in the field of research and innovation in agriculture, forestry and rural development, and acts as Innovation Support Services (ISS). The findings from ProAkis (2015) show that different types of organisations such as administrative offices, public or semi-public advisory services, rural academies/universities, producer organisations, other NGOs or private consultants engaged in the Agricultural Knowledge and Innovation System (AKIS) can act as ISS. The funding of ISS can be public, private or a mix of both. A literature review indicates that studies often focus on the larger “enabling environment” and the structure of the Agricultural Knowledge and Innovation Systems (AKIS). Moreover, many authors pay particular attention to the role of public or semi-public farm advisory organisations (Knierim et al., 2015; Sulaiman 2015). The paper is based on the analysis of more than 200 case studies of publically or privately funded interactive innovation projects within the EU and beyond. The selection of cases took place under the framework of the Horizon2020-funded European research and innovation project LIAISON. European and national databases contain several thousands of projects in agriculture, forestry and rural development. We selected projects applying the interactive innovation approach from a) EU programmes (EIP-Agri, Horizon2020, Interreg, and LIFE+); b) nationally/regionally or privately funded projects; and c) informal initiatives or networks in the agri-food, forestry, bioeconomy or nature conservation area. The results indicate that publically funded IIS play a core role for legal/administrative compliance of projects. Semi-public advisory services take up this role as well, and they are strong in linking farmers with scientists, technicians, entrepreneurs etc. However, they often exist and offer efficient ISS only for those industries that have a long tradition for a sector or area (e.g. dairy, pork, poultry or club fruit). This paper shows that different types of organisations (research institutes, farmers or producer organisations, NGOs, processing or marketing SMEs, or public bodies) provide various forms of support for the studied interactive innovation groups. No particular type of organisation such as the farm advisory services are more suitable than the other organisations for the delivery of ISS. Instead, it depends on former collaboration, the particular topic, objective or capacities available as well as the cultural/political context who engages in interactive innovation and provides innovation support.

Medienorganisationen sind daher gezwungen, gezielt zu reagieren, sich zu verändern und zu lernen. Ein theoretisches Konstrukt, das diesen Prozess erklärt, ist die Theorie des organisationalen Lernens (OL) (Senge, 2006). In der allgemeinen Managementforschung ist OL bereits ein etablierter theoretische Ansatz (Dick, 2005), bei Medienorganisationen wurde OL bislang kaum erforscht (Bernhard & Will, 2021). Die strategische Orientierung der Organisation stellt eine Möglichkeit zur Förderung des OL dar (Seçkin-Halaç, 2019). Insbesondere die strategische Technologieorientierung (TO) könnte in Anbetracht von Zukunftstechnologien hilfreich für OL sein (ebd.). Vor diesem Hintergrund beschäftigt sich dieser Beitrag mit der folgenden Frage: Besteht ein Zusammenhang zwischen der Technologieorientierung (TO) und dem organisationalen Lernen (OL) in Medienorganisationen? Zur Beantwortung dieser Frage wurde eine explorative Onlineumfrage (Zeitraum: Dez. 2020 bis Jan. 2021) unter deutschen Medienmanager*innen (N=46) durchgeführt. Für die Untersuchung wurden die Instrumente von Hakala & Kohtamäki (2011) für die TO und von Marsick & Watkins (2003) für das OL übernommen. Die Umfragedaten wurden mithilfe der Rangkorrelation nach Spearman analysiert. Kernergebnis der Untersuchung ist, dass ein signifikanter Zusammenhang zwischen TO und OL besteht.

Particularly, the log parameters exert a considerable influence on the volume of the stack, such as (1) the log midpoint diameter, (2) average bark thickness, (3) crookedness, and (4) log taper. Although many of these parameters have already been studied and some are already considered in many countries when measuring wood stacks, their influence has not been analyzed individually so far since a broad statistical database is needed and the data collection is very costly. Consequently, a 3D-simulation model was developed based on a cross-platform game engine. This model generates virtual wood stacks based on a data set of logs which are defined by the user. The simulation of a stack can be done in a few seconds only and each stack generated can be visualized once all iterations are done. The simulation results are the stacked cubic volume, solid wood cubic volume, and the respective conversion factors. The model, fed with both real data and user-defined data, allows for a detailed analysis of the effect of each parameter on the results, as the user can vary their values discretionary. To obtain the first results from real data, 1000 logs of Scots pine (Pinus sylvestris L.) were measured. The first simulations based on these data show reliable results and it is possible to quantify the influence of the proportion of crooked wood in a pile on the stack volume and the conversion factor. In addition, the results are highly in line with the real trials that have already been performed in parallel. A further scientific evaluation and statistical analysis will be done in a second study phase. However, the model already provides a reasonable tool that is easy to apply for the forest and wood industry in order to make the most accurate estimate possible of the solid wood content in a wood pile.

T2 - 22. Tagung der Deutschen Gesellschaft für allgemeine und angewandte Entomologie e.V. (DGaaE) 2023 in Bozen, Italien N2 - Insect biomass has been used as an ecological indicator in the past, but in recent years has become a key metric in the study of insect population trends, especially since first reports about the so-called insect decline (e.g. “Krefeld study” of 2017). However, measuring insect biomass can be methodologically challenging, and very labour intensive. For many datasets, weight measurements are not available and the original samples may have already been lost. Size-weight equations provide a straightforward method for estimating insect biomass when the insect’s body length is known. If insects have been determined to species level one can also use the average body length given in literature. Based on the correlation between the body length and the weight of an insect, there is a variety of size-weight equations for different groups of insects. They are widely used in insect research, but have rarely been tested with independent data. We evaluated two size-weight models for carabid beetles, by Szyszko (1983) and Booij et al. (1994), drawing on previously published independent data by comparing model predictions with actual measurements of biomass, using relative deviation graphs and observed versus predicted from regression. Moreover, we also tested if the inclusion of additional taxonomic parameters, in this case subfamily, can improve results. We found that both models produced systematically biased results: Szyszko´s model gave more accurate results for larger species, while the model of Booij et al. did so for smaller species. This bias is most likely caused by the different origin of the respective training data. This underlines the restricted applicability of such models. We demonstrate that additional taxonomic parameters have the potential to increase the accuracy of size-weight equations and represent a potential solution to the issue of restricted applicability. As actual biomass measurements for carabids are scarce, data availability is limited to only few subfamilies. Until data on more subfamilies become available, we recommend a combined use of both evaluated models: Szyszko’s model for carabids ≥ 11.8 mm, and the model of Booij et al. for carabids < 11.8 mm, respectively.

In addition to heat transfer and pressure, closed and open systems differ primarily in the choice of treatment atmosphere mainly used to prevent combustion (Sandberg et al. 2021). Although many studies in recent years have investigated influencing process parameters such as temperature, pressure or treatment duration, there exists a knowledge gap regarding the influence of the treatment atmosphere or its behaviour during the treatment process (Candelier et al. 2016). Therefore, this study aims to analyse different oxygen-nitrogen concentrations in the treatment atmosphere at different residual oxygen levels during the process duration and their influence on different property parameters of Fagus sylvatica (L.).

As the properties of some of these wood species cannot meet the high demands of this field of application, processes are being sought that can achieve improvements. In recent years, many studies have shown that different modification methods, such as furfurylation, thermal treatment, densification or impregnation methods, can partly improve wood properties such as elasticity, strength values, damping behaviour, but also moisture behaviour and wood moisture content significantly. The extent to which different modification processes and their positive changes in properties can be combined with each other and thus achieve further improvements will become increasingly important in the future, not only in instrument making but also in other areas of application. Therefore, this study investigated the influence of thermal treatment followed by linseed oil impregnation of wood on its sound propagation velocity and the associated acoustic properties of characteristic impedance and acoustic radiation.

Various methods have been established, which differ mainly in the choice of treatment atmosphere, but also in the associated treatment duration and temperature. Part of the present investigation was to compare a thermal-vacuum process with a process which takes place in an oxygen-reduced atmosphere, with regard to various property changes. The results show that both processes achieved similar results in terms of dynamic acoustic property changes. Larger differences were found with regard to moisture behavior and color change.

The sound board, which is mainly made of spruce or cedar, transfers the vibration of the strings to the resonance body by means of the bridge. The sides and the back of the guitar rather reflect the sound of the acoustic vibrations and are predominantly made of tropical hardwoods like palisander, mahogany or ebony species. These species have limited availability and are listed on the CITES Annex I and II. To substitute tropical wood species, thermally modified European wood species with improved acoustic properties and dimensional stability may be used. Although the acoustic reflection of the sides and the back parts of a guitar body is an important property, there is not much knowledge about this reflection behaviour of wood. A few studies like the work of Hong (1989), Kang (2010) or Smardzewski et al. (2013) investigated the sound absorption properties of unmodified wood. Subsequently this study considers the sound absorption coefficients of unmodified and thermally modified European wood species in comparison to an unmodified tropical wood species.

Due to the current CITES regulation of January 2017 regarding the trade of tropical woods, it becomes inevitable to generate alternative materials with similar material properties to be generated and established. Part of this study is an acoustic comparison of two guitars. One made of untreated tropical wood [Dalbergia nigra Benth.)] and one made of European thermally modified wood (TMT) species. [Pyrus (L.) and Alnus (Mill.)]. The method used allows a significant statement about the acoustic radiation performance of stringed and plucked instruments. The experimental setup consists of an impulse hammer for excitation of a force in the center of the bridge and a microphone for recording the signal radiated by the guitar body at a distance of one meter from the sound hole. A front-end was used to record the data, and further processing was done using analysis software to determine frequency response functions (FRFs) of the two instruments. The FRFs determined can be subdivided into several ranges which contain the different acoustic information about bass range, loudness, clarity, brightness and sharpness of the instruments. Examination of the frequency ranges reveals an acoustic similarity between the two guitars. Slight differences can be seen in the bass and loudness areas, where the guitar from TMT has a higher average level. Clearer differences are offered by the areas of clarity, where the guitar made of tropical wood shows a higher average level. In summary, the method gives an efficient acoustic impression as a function of the natural frequencies of the two guitars. The measured data show similarities and thus comparable acoustic properties of the instruments. However, additional effects such as psychoacoustic sensations or musical taste for the complete acoustic impression of an instrument are also of importance. Therefore, further empirical and fundamental research is needed to obtain a more detailed acoustic impression of the instruments.

As a result of a long-term heat treatment on beech wood (Fagus sylvatica L), the degradation or decomposition reaction of wood-bound cellulose, hemicellulose and lignins in the low temperature range up to 150°C investigated. For this purpose, test series in the dry state are thermally treated over a period of 6 weeks at a temperature of 120°C and 140°C. Weekly, the mass and dimensions of the test specimens are recorded in order to effectively track the density curve. The mechanical resistance of the wood substrate was realized by a hardness measurement in a weekly period.

Holztechnologischen Kolloquiums Dresden 28.-29. April 2022 N2 - Aufgrund von Rohstoffknappheit auch bei nachwachsenden Rohstoffen kann das Recyceln von Holz und Holzwerkstoffen auch im Möbelsektor nur an vorletzter Stelle, vor der thermischen Verwertung, stehen. Davor gilt es, schon bei der Produktion den Materialeinsatz zu reduzieren bzw. Möbel so zu gestalten, dass eine verlängerte Nutzung möglich ist. Insgesamt muss die Produktnutzung intensiviert werden. Dafür sind unter anderem geeignete Businessmodelle erforderlich. Hiermit beschäftigt sich das Projekt PERMA an der HNEE. Wird Holz dann zum Altholz, muss die Nachnutzungsquote deutlich erhöht werden. Mit der Identifizierung und Indexierung von Altholz befasst sich daher das Kooperations-projekt WIn-Altholz. Sind allerdings Holzspan- und Holzfaserwerkstoffe beschä-digt oder werden nicht mehr benötigt, gibt es bisher keine sinnvollen Nachnut-zungsszenarien. Das Forschungsprojekt „Respan“ will nun ein Recyclingverfahren entwickeln, dass die Nachnutzung möglichst aller Bestandteile der Werkstoffe realisiert.
