Such systems are often referred to as smart systems because they can autonomously monitor and respond to environmental conditions and can be integrated both indoors and outdoors to detect, for example, structural anomalies. However, these systems typically have high energy consumption, data overload, and large equipment sizes, which makes them difficult to install in constrained spaces. Therefore, three challenges remain unresolved: efficient energy use, accurate data measurement, and compact installation. To address these limitations, this study proposes a two-to-one threshold sampling approach, where the CO2 measurement is activated when the specified T and RH change thresholds are exceeded. This event-driven method avoids redundant data collection, minimizes power consumption, and is suitable for resource-constrained embedded systems. The proposed approach was implemented on a low-power, small-form and self-made multivariate sensor based on the PIC16LF19156 microcontroller. In contrast, a commercial monitoring system and sensor modules based on the Arduino Uno were used for comparison. As a result, by activating only key points in the T and RH signals, the number of CO2 measurements was significantly reduced without loss of essential signal characteristics. Signal reconstruction from the reduced points demonstrated high accuracy, with a mean absolute error (MAE) of 0.0089 and root mean squared error (RMSE) of 0.0117. Despite reducing the number of CO2 measurements by approximately 41.9%, the essential characteristics of the signal were saved, highlighting the efficiency of the proposed approach. Despite its effectiveness in controlled conditions (in buildings, indoors), environmental factors such as the presence of people, ventilation systems, and room layout can significantly alter the dynamics of CO2 concentrations, which may limit the implementation of this approach. Future studies will focus on the study of adaptive threshold mechanisms and context-dependent models that can adjust to changing conditions. This approach will expand the scope of application of the proposed two-to-one sampling technique in various practical situations.

T1 - High-resolution in situ imaging reveals size-specific moonlight responses in zooplankton diel vertical migration JF - Scientific Reports N2 - Light is the primary cue driving zooplankton diel vertical migration (DVM), a strategy that balances predation risk with resource access. However, DVM is often oversimplified, with limited consideration of how light-driven risks and resource needs vary across taxa and life stages. This simplification is partly due to constraints on collecting high-resolution, size-resolved data —especially at night, when subtle shifts in illumination reshape nocturnal risk landscapes. To overcome these limitations, we deployed a high-resolution in situ modular Deep-focus Plankton Imager and an image-recognition approach to quantify fine scale DVM and body sizes of Cladocerans and Copepods in Lake Stechlin, Germany. Data was collected from day into night and across moonrise and was compared with environmental data from vertical profiling sondes. Typical DVM patterns emerged, with deeper daytime distributions, however, moonlight introduced additional behavioural complexity: larger individuals avoided illuminated layers, likely managing predation risk, while smaller individuals moved into these layers, possibly exploiting foraging opportunities and reduced risk. These light-mediated shifts were further shaped by ecological conditions; copepods tracked food-rich layers regardless of light levels at night, while cladocerans showed light-dependent responses to both temperature and food, such that light caused them to avoid otherwise favourable (warm, food-rich) layers. Our approach provides new insight into how zooplankton navigate nocturnal lightscapes, revealing size- and taxon-specific strategies. By establishing size-dependent responses to natural moonlight, this work provides a crucial baseline for predicting how artificial light at night may restructure zooplankton communities and destabilize freshwater food webs.

Since light pollution is rarely integrated into conservation approaches, effective mitigation strategies towards environmentally friendly lighting that drastically reduce insect attraction are urgently needed. Here, we tested novel luminaires in two experiments (i) at a controlled experimental field site and (ii) on streets within three municipalities. The luminaires are individually tailored to only emit light onto the target area and to reduce spill light. In addition, a customized shielding renders the light source nearly invisible beyond the lit area. We show that these novel luminaires significantly reduce the attraction effect on flying insects compared to different conventional luminaires with the same illuminance on the ground. This underlines the huge potential of spatially optimized lighting to help to bend the curve of global insect decline without compromising human safety aspects. A customized light distribution should therefore be part of sustainable future lighting concepts, most relevant in the vicinity of protected areas.

ALAN attracts nocturnal insects from their native ecosystems and disturbs their functions in the food web. Road lights in this context are ubiquitous and relevant ALAN sources that are often not considered in conservation approaches. In a previous study we showed that shielded LED road lights are suited to be part of conservation measures by effectively reducing the attraction of nocturnal insects. Here we show that this positive effect holds true for parasitoid wasps in an experimental BACI design (Before-After-Control-Impact). Combining morphological with molecular and phylogenetic analyses, we identified 106 individuals (62 morphotypes) of a minimum of 45 genera out of 13 Hymenoptera families. We were able to identify 21 species, 11 of which are newly reported in Southern Germany (Baden-Württemberg). Further combining knowledge on life history and host appearance from our data and the literature, we discuss potential impacts of ALAN ranging from an influence on nocturnal pollination via parasitoid pressure on moth species and biological control of invasive pest species to tritrophic interactions between primary and secondary parasitoids. We conclusively think that shielded LED road lights will reduce the ecological impact of ALAN on parasitoid wasps in a large and undescribed number of taxa with different host associations, likely affecting associated ecosystem functions such as biological control.

A1 - Scheeg, Jochen T1 - Alternative digital platforms: comparative analysis through the lens of Corporate Aikido JF - Information Systems and e-Business Management N2 - Competing with dominant players in the digital platform (DP) economy is an increasingly complex and expensive endeavor for alternative digital platform (ADP) providers trying to disrupt established platform ecosystems. Nevertheless, ADPs position themselves deliberately in the competitive space of large competitors, targeting customer groups whose values and mindsets differ from mainstream DPs. Although there are many examples to find in practice, the variety of ADPs across different DP ecosystems and industries, especially in regards of strategic objectives, directions and characteristics, has not been researched in-depth yet. Based on a systematic, practice-based artifact review, this paper analyses and compares 105 ADPs in the competitive space of dominant DP ecosystem players. The study utilizes the theory of Corporate Aikido as an analytical framework, mapping the strategic elements of overthrowing established value propositions and turning a competitors’ strengths into weaknesses. Our findings indicate that privacy- and security-awareness, empowerment and inclusivity, premium quality and curation, open source and free access, uncensored, transparent and decentralized platforms as well as ecological and climate-friendly offers shape the landscape of alternative approaches in today’s DP economy. The results are subsequently discussed, yielding managerial implications and future opportunities for DP research.

A1 - Scheeg, Jochen T1 - Coping Practices of Small- and Medium-Sized Enterprises Facing Power Asymmetry in Digital Platform Business JF - Strategic Change N2 - Digital platform (DP) enterprises have risen to the top of the global economy by inverting traditional business models. They earn money through matchmaking, transaction facilitation, and efficient orchestration of other stakeholders' resources. Small- and medium-sized enterprises (SMEs) play a decisive role in this success story: they offer products and services on many leading DPs and thereby feed platform networks as sellers and suppliers. On the other hand, while DPs enable SMEs to reach new customers and outsource costly managerial tasks, many SMEs struggle with the negative consequences of asymmetric power dynamics and dependency risks in platform business. This paper analyzes 14 cases of SMEs that face power asymmetry as DP value providers, unraveling challenges encountered and coping practices employed in this situation. The findings reveal that power asymmetry between dominant DPs and SMEs creates significant challenges, including exploitative relationships, loss of autonomy, surveillance pressures, and devaluation of SME contributions, while SMEs cope through disintermediation, multi-homing, individual resistance tactics, and striving for more equitable DP models. Moreover, three relationality types are identified: DPs being SMEs' “partners,” “tools,” and “necessary evil.” This article offers a new perspective on boundaries of SME strategies in the DP economy and contributes with empirical insights to the advancing field of entrepreneurial platform research.

This phenomenon is known as artificial skyglow. Its consequences on freshwaters are largely unknown. In a large-scale lake enclosure experiment, we found that skyglow at levels of 0.06 and 6 lux increased the abundance of anoxygenic aerobic phototrophs and cyanobacteria by 32 (+/- 22) times. An ecosystem metabolome analysis revealed that skyglow increased the production of algal-derived metabolites, which appeared to stimulate heterotrophic activities as well. Furthermore, we found evidence that skyglow decreased the number of bacteria-bacteria interactions. Effects of skyglow were more pronounced at night, suggesting that responses to skyglow can occur on short time scales. Overall, our results call for considering skyglow as a reality of increasing importance for microbial communities and carbon cycling in lake ecosystems.

JF - European Journal of Education N2 - The study examines the effectiveness of microlearning in developing the capacity to address climate change and adapt to environmental challenges. Conducted as an online field experiment with 140 participants, the study focused on the impacts of smartphone use as an illustrative learning domain for education in climate change-related areas. Using a pre–post research design and simultaneous equation models, the study found improvements in knowledge retention, with a median increase of 38%. The results indicated that the brief microlearning units also promoted sustainability action competencies, such as confidence in one's influence and willingness to act sustainably. This suggests that higher-order learning processes were also triggered, although to a much lesser extent. Furthermore, learner satisfaction was identified as a mediating variable for these positive outcomes. The study concludes that short bursts of knowledge delivered through microlearning activities can be used alongside traditional training methods to build the critical skills needed for initiatives such as the EU Green Deal.

Despite extensive work, the superconducting pairing symmetry in La3⁢Ni2⁢O7 remains unresolved, with conflicting results even for identical methods. We argue that different superconducting states in La3⁢Ni2⁢O7 are in close competition and highly sensitive to the choice of interaction parameters as well as pressure-induced changes in the electronic structure. Our study uses a multiorbital Hubbard model, incorporating all Ni 3⁢𝑑 and O 2⁢𝑝 states. We analyze the superconducting pairing mechanism of La3⁢Ni2⁢O7 within the random phase approximation and find a transition between 𝑑-wave and sign-changing 𝑠-wave pairing states as a function of pressure and interaction parameters, which is driven by spin fluctuations with different wave vectors. These spin fluctuations with incommensurate wave vectors cooperatively stabilize a superconducting order parameter with 𝑑𝑥2−𝑦2 symmetry for realistic model parameters. Simultaneously, their competition may be responsible for the absence of magnetic order in La3⁢Ni2⁢O7, demonstrating that magnetic frustration and superconducting pairing can arise from the same set of incommensurate spin fluctuations.
