The study's objective was to explore the effects of incorporating mango peel and apple pectin into pig feed. Batch fermentations using sow faeces were conducted to assess the fermentability of the substrates over a 24-hour incubation period. Subsequently, a feeding experiment was conducted using post-weaning piglets to examine the impact of adding 1 % or 2 % (w/w) mango peel and apple pectin to their diet. The in vitro fermentation studies with sow faeces showed increasing lactate and short-chain fatty acid concentrations when apple and mango pectin were added as substrates. The feeding trial indicated no significant impact on piglets' performance, nor the apparent praecaecal digestibility of crude protein was altered, while the apparent praecaecal digestibility of crude fat decreased with the addition of 1 % apple pectin, but increased with 2 % mango peel. Concentrations of microbial metabolites in the digesta were similar, and only slight variations were observed in the bacterial levels as determined by qPCR. In the treatment groups, enhanced utilisation of mango peel and apple pectin by the faecal microbiota was noted compared to the control group (BIOLOG test). In summary, incorporating small quantities of mango peel and apple pectin resulted in only mild alterations within the piglets' digestive system. Additional research to determine the optimal levels for effective usage of mango peels and apple pectin in piglet diets is required.

However, studies revealed drawbacks like antimicrobial resistance and environmental impact. Since 2022, the EU limits zinc inclusion levels to 150 mg total zinc per kg. Therefore, alternative strategies for replacing high levels of zinc are of great interest. This study compares a potentiated zinc oxide source (HiZox®) and feed grade zinc oxide at various levels on piglet performance, fecal consistency and fecal microbiome. The trial involved a total of 1,440 healthy weaned piglets (DanBred × Duroc; 50% barrows, 50% gilts; initial BW 10.1 ± 1.46 kg) over the 28-day duration of the experimental period. Piglets were randomly assigned to 12 treatment groups, each consisting of 12 pens, with 10 piglets per pen. The trial comprised two periods: the starter period (days 1 to 14) focused on comparing the two zinc products, while all animals received a diet supplemented with 150 mg/kg of potentiated ZnO in the grower period (days 15 to 28). Treatment groups receiving feed grade ZnO were denoted as Z150, Z300, Z600, Z900, Z1500, and Z3000, while corresponding groups with the potentiated ZnO product were labeled H150, H300, H600, H900, H1500, and H3000, respectively. Body weight (BW) and feed intake (FI) were measured for every pen at days 1, 14 and 28. Fecal samples were collected on the same days. During the starter phase (days 1 to 14), potentiated ZnO significantly improved average daily gain (ADG) compared to feed-grade ZnO (P ≤ 0.001), with the highest values observed at 3000 mg/kg (H3000: 247 g/d vs. Z3000: 233 g/d). Feed intake (FI) was also higher in potentiated ZnO groups (P ≤ 0.001), and feed conversion ratio (FCR) was more efficient (e.g., H3000: 1.2 vs. Z3000: 1.24; P = 0.001). In the grower phase residual effects from the starter phase persisted: animals previously fed potentiated ZnO had improved FCR (P = 0.003). Fecal microbiota analysis revealed that higher zinc levels reduced Lactobacillus abundance (P ≤ 0.001) and increased the presence of genera typical of adult pigs, such as Clostridium sensu stricto 1 and Terrisporobacter (P < 0.01). In conclusion, based on the observed shift in fecal microbiota composition characterized by a reduction in lactobacilli and an increase in proteobacteria due to heightened dietary zinc levels, it is advised to adjust zinc supplementation to 150 mg/kg after the initial 2 wk post-weaning.

However, considering that bark makes up about 10–20% of the tree volume, there is a considerable amount of material that can be exploited and should be investigated in terms of a resource-efficient bioeconomy. One way to use bark as a raw material for innovative products could be as a substrate within mycelium-bound composite materials. However, since one of the natural functions of bark is to inhibit microbial infestation of the trees, it was unclear whether bark could be utilized in this manner. Therefore, we investigate in this study the possibilities of producing such composites by evaluating the performance of several bark-fungus combinations. Three different barks (from Douglas fir, Scots pine and European birch) and two species of fungi ( Ganoderma resinaceum and Ganoderma adspersum ) were selected for the experiments. Mycelium growth rates were evaluated with a newly developed method using fungal “growth tubes”. In addition, composites were prepared for performance tests from pure bark and 1:1 mixture of bark and beech wood sawdust. Composites made of mixed bark and beech wood were mostly well overgrown with a thick layer of mycelium on the surface, supporting higher compression strengths. The mycelium layer on the composites made with tree bark only was considerably thinner, resulting in lower compression strength. Water absorption potential was found to be highly dependent on the mycelium layer on the composite surfaces, which has substantial hydrophobic properties. Overall, although the required incubation times tend to be longer than for other commonly used substrates, our experiments demonstrate that bark clearly represents a potential co-substrate for the production of mycelium-bound composites.

The European Union’s ability to harness this potential depends on empowering energy citizens, fostering active engagement, and overcoming resistance to RE deployment. European energy law introduced “renewable self-consumers” and “active customers” with rights to consume, sell, store, and share RE, alongside rights for citizens collectively organised in energy communities. This article explores conditions for inclusive citizen engagement and empowerment within the RE system. Building on an ownership- and governance-oriented approach, we further develop the concept of energy citizenship, focusing on three elements: conditions for successful engagement, individual versus collective (financial) participation, and the role of public (co-)ownership in fostering inclusion. The analysis is supported by 82 semi-structured interviews, corroborating our theoretical lens. Findings show that participation, especially of vulnerable consumers, relies on an intact “engagement chain,” while energy communities remain an underused instrument for inclusion. Institutional environments enabling municipalities and public entities to act as pace-making (co-)owners are identified as key. Complementing the market and the State, civil society holds important potential to enhance engagement. Inspired by the 2017 European Pillar of Social Rights, we propose a corresponding “European Pillar of Energy Rights.” KW - governance KW - renewable energy communities KW - energy citizenship KW - (co-)ownership KW - socio-legal institutions KW - energy justice Y1 - 2026 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:kobv:eb1-opus-10895 SN - 2076-0760 VL - 15 IS - 1 PB - MDPI ER - TY - JOUR A1 - Hirsch, Mareike A1 - Greiner-Müller, Evgenia A1 - Boden, Simon A1 - Hillenmeyer, Katharina A1 - Mattes, Arno A1 - Schuler, Johanna A1 - Spathelf, Peter A1 - Maaten, Ernst van der A1 - Maaten-Theunissen, Marieke van der A1 - Seifert, Thomas T1 - Drought and masting affect growth allocation along the stem axis in beech, oak, fir and spruce in temperate forests JF - Trees N2 - In temperate forests, tree growth and vitality are significantly influenced by drought, often reflected by low stem diameter growth.

This study aimed to characterize the taxonomic composition and functional potential of the camel rumen archaeome using whole-genome shotgun metagenomic sequencing. Across the seven healthy racing camel rumen samples, the archaeal community was dominated by Euryarchaeota (50.1 ± 0.02%) and the Methanomada group (49.7 ± 0.03%), with Methanobacteriaceae and Methanobrevibacter representing the predominant family and genus, respectively. Species-level analysis revealed Methanobrevibacter sp. YE315 and Methanobrevibacter millerae as the most abundant archaeal species across all samples. Alpha-diversity analyses indicated a diverse and evenly distributed archaeal population in the camel rumen. Beta-diversity based on Bray–Curtis and Jaccard dissimilarities demonstrated strong similarity among samples, highlighting a conserved archaeal community structure across individuals. Core microbiome assessment (≥ 80% occurrence) identified seven dominant Methanobrevibacter species as the stable core archaeome. Functional profiling revealed a consistent metabolic repertoire dominated by methanogenesis (PWY-5209), amino acid biosynthesis, and nucleotide metabolism pathways. Functional alpha-diversity metrics and beta-diversity clustering highlighted low inter-sample variability and a stable functional architecture. Overall, the camel rumen archaeome exhibited a stable and conserved community composition and functional architecture, underscoring its central role in hydrogen utilization and methane production within the rumen ecosystem. Although based on a small number of animals from a single location and therefore descriptive in nature, this study provides a comprehensive metagenomic overview of the taxonomic and functional profiles of the camel rumen archaeal community.

However, this region is still underrepresented in fire ecology research. To help to fill this knowledge gap, we investigated post-fire vegetation composition and mean Ellenberg indicator values (EIV) in two burned Scots pine forests in NE Germany with different levels of salvage logging (no, partial, complete) in the first 6 years after a severe fire. Results Vegetation composition of burned plots differed drastically from unburned control plots, resulting in enhanced species richness (mainly due to open land species) and increased EIV for light, reaction, and nitrogen. In the first year, species richness was generally lower on completely salvage logged plots, as was EIV for light, reaction, and nitrogen. On non-salvage- and partially salvage logged plots, total species richness and the number of open land species, as well as forb cover, increased in the first 3 years and decreased thereafter. The number of forest species, as well as the cover of grasses and bryophytes, increased continuously on all plots. EIV for moisture, reaction, and nitrogen showed a temporal decrease. Conclusions We were able to show that even in the short period of up to 6 years after fire, vegetation changed rapidly. Post-fire species composition shifted from early open land pioneer species towards late successional forest species. Decreasing EIVs for reaction and nutrients indicate that the temporary increase in nutrient availability quickly dissipates, probably due to nutrient leaching. Post-fire management has a strong influence on post-fire vegetation. Even if some successional patterns remained similar for all salvage logging groups, recolonization of completely salvage logged plots was slower, resulting in lower species richness and ground vegetation cover. In the next years, the shift from pioneer towards late successional climax species will probably continue in our study areas as site conditions are expected to change further. N2 - Resumen Antecedentes Los incendios de vegetación han quemado grandes áreas de bosques en Europa Central en años recientes, y se predice que el riesgo de incendios aumentará. Sin embargo, esta región está todavía sub-representada en relación con las investigaciones sobre incendios de vegetación. Para ayudar a llenar esta brecha en el conocimiento, investigamos la composición post-fuego y los valores del indicador medio Ellenberg (EIV) en dos bosques quemados de pino silvestre en el NE de Alemania con diferentes niveles de aprovechamiento post disturbio (sin aprovechamiento, aprovechamiento parcial, y total) en los últimos seis años luego de un incendio severo. Resultados La composición de la vegetación de las parcelas quemadas difirieron drásticamente comparadas con las de los controles (no quemadas), resultando en incrementos en la riqueza de especies (fundamentalmente por especies de áreas abiertas) y también en incrementos en EIV para la luz, pH y nitrógeno. En las parcelas quemadas pero no aprovechadas o parcialmente aprovechadas luego del incendio, la riqueza total de especies y el número de especies de áreas abiertas y también la cobertura de malezas de hoja ancha, se incrementaron en los primeros tres años post-incendio y luego decrecieron. El número de especies forestales, como así también la cobertura de pastos y briófitas se incrementaron continuamente en todas las parcelas. El EIV para humedad, pH y nitrógeno mostraron un descenso temporal. Conclusiones Mostramos que aún en un periodo corto de hasta seis años después del fuego, la vegetación cambió rápidamente. La composición de especies en el post-fuego cambió desde especies pioneras tempranas de áreas abiertas, a especies forestales de estadios sucesionales tardíos. El decremento del EIV para el pH y nutrientes indican que el rápido incremento en la disponibilidad de nutrientes se disipa rápidamente, probablemente debido a su lixiviación. El manejo en el post-fuego tiene una muy fuerte influencia en la vegetación resultante en la etapa del post-fuego. Aún cuando algunos patrones sucesionales permanecen de manera similar para todos los grupos de aprovechamiento en el pos-fuego, la recolonización en las parcelas donde el aprovechamiento fue total resultó más lenta que en las otras, resultando en una menor riqueza de especies y menor cobertura de vegetación. En los próximos años, el cambio de especies pioneras hacia especies climáxicas propias de la sucesión tardía probablemente ocurra en nuestras áreas de estudio, a medida que se vayan produciendo los cambios esperados en las condiciones de sitio.

Although Côte d’Ivoire is the world’s leading cocoa producing country, most cocoa farmers live far below the local Living Income benchmark. Further, given that many poverty-related sustainability challenges persist, a main element of public and private sustainability interventions center on demonstrating GAPs to farmers. Yet, there is no clear picture of not just the isolated associations of GAPs training on farmers’ production and wellbeing but also their actual mid-term sustainability. Furthermore, farmers’ perspectives on GAPs and major challenges related to their implementation are still not well understood. Applying a mixed methods approach, based on survey data ( N  = 521) and farmer interviews ( N  = 52) from two different cocoa loops in Côte d’Ivoire, we assess structural dimensions of GAPs training, costs and benefits of adoption, as well as contribution to cocoa yields and revenues. While cost-benefit analyses and robust linear regression models show positive effects of GAPs training on cocoa yields and revenues, our insights from qualitative data revealed largely unrecognized challenges, such as negative impacts on health and livelihood perceptions, as well as major structural barriers to GAPs adoption. We argue that cocoa farmers face limitations in applying GAPs that are beyond their control. Given the urgent need to break the cycle of poverty in cocoa production, the responsibilities of other key stakeholders in the cocoa value chain for reducing farmers’ income gaps must be clearly defined.

Transdisziplinarität hat es sich auf die Fahnen geschrieben, zur Lösung komplexer realweltlicher Probleme beizutragen, sodass gesellschaftliche Wirkungen einen wichtigen Aspekt in diesem Forschungsmodus ausmachen (Kny, Claus, et al., 2023). Um diese noch gezielter ansteuern zu können, hat sich in den letzten Jahren die „Wirkungsorientierung“ als wichtiger methodischer Ansatz entwickelt. Das Verbundvorhaben InNoWest arbeitet hieran nach der Methodik von Schäfer et al. (2021, 2024), deren Grundlage die Theory of Change bildet. Das weitere Hauptmerkmal transdisziplinärer Forschung ist die Zusammenarbeit mit außerwissenschaftlichen Akteur:innen, die von Anfang an in den Prozess der Wirkungsorientierung einbezogen werden. In InNoWest wurde der Prozess jedoch ohne Praxisbeteiligung begonnen. Um die Konsequenzen einer nachträglichen Einbeziehung zu explorieren, wurde deshalb ein Workshop konzipiert und durchgeführt, der Teile des wissenschaftlichen Teams und ausgewählte Praxispartner:innen eines Teilvorhabens zusammenbrachte und den Beteiligten die Möglichkeit gab, die in früheren Workshops erarbeitete Theory of Change (Wirkungspfad) anzupassen. Anschließend wurden der Audiomitschnitt des Workshops und der angepasste Wirkungspfad anhand von aus der Literatur abgeleiteten Kriterien analysiert. Die Resultate wurden mit den Ergebnissen einer Teilnehmendenbefragung und Aussagen der Co-Moderation trianguliert. Hierbei zeigte sich, dass die Theory of Change durch den Workshop zwar an methodischer Qualität verlor, jedoch gleichzeitig Zustimmung von den Beteiligten erfuhr und in ihrer Funktion als Übersetzungshilfe zwischen Wissenschaft und Praxis gestärkt wurde. Zudem erhöhte die Anpassung des Wirkungspfads die Wahrscheinlichkeit, dass die Ergebnisse des Teilvorhabens verstetigt werden. Es wurde deutlich, dass die Zusammenarbeit im Teilvorhaben bisher eher der consulting transdisciplinarity (Mobjörk, 2010) zuzuordnen ist, die nicht dem Idealbild der gleichrangigen Zusammenarbeit von Wissenschaft und Praxis entspricht. Die Verständigung über Ziele und Rollen im Workshop erlaubte es jedoch, Offenheit für andere Modi der Zusammenarbeit zu zeigen, die auf die bisherige, als positiv bewertete Zusammenarbeit aufbauen. Die im Workshop diskutierten Themen deuteten auf den Beginn einer neuen Phase der Arbeit im Projekt hin, in der der Fokus stärker auf dem Transfer der Ergebnisse liegt. Dies stärkt ebenfalls mittel- und langfristige Wirkungen. Damit diese Wirkungen tatsächlich eintreten, muss die Wissenschaft-Praxis-Zusammenarbeit fortgesetzt werden. Es braucht jedoch auch Unterstützung auf struktureller Ebene, wie geeignete Förderformate.

However, the impact of the individual and combined use of organic and mineral soil fertility amendments on food security and nutrition is not fully understood. To inform evidence‐based policymaking, this study evaluates the individual and synergistic impacts of organic and mineral soil amendments as part of an integrated soil fertility management technology on food security and nutrition. We apply the multinomial endogenous switching regression and inverse probability weighted regression adjustment to survey data collected from 768 farm households in Cameroon. Our results indicate that the combined use of organic and mineral soil amendments has the greatest positive association with household dietary diversity, followed by the individual use of organic and mineral soil amendments, respectively. We find that mineral soil amendments drive the consumption of meat, pulses and nuts, and roots and tubers, whereas organic soil amendments are associated with the consumption of most food groups except fruits and meat. The combined use of mineral and organic soil amendments favors the consumption of cereals, milk and dairy products, eggs, fruits, meat, pulses and nuts, and roots and tubers, highlighting the value of integrated soil fertility management. Our findings reaffirm the value of integrated soil fertility management for food security and nutrition and underscore the need for interventions to promote integrated soil fertility management practices in agrarian settings.

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.

In der aktuellen Förderphase der Landesinitiative Forschungsdatenmanagement Brandenburg (FDM-BB) mit dem Projekt „Institutionalisiertes und nachhaltiges Forschungsdatenmanagement in Brandenburg“ (IN-FDM-BB), verfolgen alle brandenburgischen Hochschulen das übergreifende Projektziel lokale Kompetenzen für das FDM aufzubauen. Zur Vermittlung dieser FDM-Kompetenzen wurden für die Zielgruppe der Forschenden Veranstaltungen durchgeführt. Der Bericht bezieht sich auf die Evaluation eines Teils dieser Veranstaltungen und hat das Ziel Empfehlungen zur Verbesserung des Veranstaltungsangebots und deren Inhalte zu geben. Dabei sind die Ergebnisse als Lessons-Identified zu verstehen, denn in der Literatur wird zwischen dem Zeitpunkt unterschieden, an dem eine Lesson erst identifiziert und im nächsten Schritt umgesetzt und Lehren gezogen wurden.
