- Abstract
Ecosystem functions and services are severely threatened by unprecedented global loss in biodiversity. To counteract these trends, it is essential to develop systems to monitor changes in biodiversity for planning, evaluating, and implementing conservation and mitigation actions. However, the implementation of monitoring systems suffers from a trade‐off between grain (i.e., the level of detail), extent (i.e., the number of study sites), and temporal repetition. Here, we present an applied and realized networked sensor system for integrated biodiversity monitoring in the Nature 4.0 project as a solution to these challenges, which considers plants and animals not only as targets of investigation, but also as parts of the modular sensor network by carrying sensors. Our networked sensor system consists of three main closely interlinked components with a modular structure: sensors, data transmission, and data storage, which are integrated into pipelines for automated biodiversity monitoring. We present our own real‐world examples of applications, share our experiences in operating them, and provide our collected open data. Our flexible, low‐cost, and open‐source solutions can be applied for monitoring individual and multiple terrestrial plants and animals as well as their interactions. Ultimately, our system can also be applied to area‐wide ecosystem mapping tasks, thereby providing an exemplary cost‐efficient and powerful solution for biodiversity monitoring. Building upon our experiences in the Nature 4.0 project, we identified ten key challenges that need to be addressed to better understand and counteract the ongoing loss of biodiversity using networked sensor systems. To tackle these challenges, interdisciplinary collaboration, additional research, and practical solutions are necessary to enhance the capability and applicability of networked sensor systems for researchers and practitioners, ultimately further helping to ensure the sustainable management of ecosystem

Monitoring insect abundance or species richness at high spatial and temporal resolution is difficult due to personnel, maintenance, and post‐processing costs as well as ethical considerations. Non‐invasive automated insect monitoring systems could provide a solution to address these constraints. However, every new insect monitoring design needs to be evaluated with respect to reliability and bias based on comparisons with conventional methods.In this study, we evaluate the effectiveness of an automated moth trap (AMT), built from off‐the‐shelf‐hardware, in capturing declines in moth abundance, by comparing it to a conventional, lethal trap. Both trap types were operated five times on 16 plots from the beginning of July 2021 to the end of August 2021.On average AMTs recorded fewer individuals than conventional traps. However, both trap types depicted the same seasonal decline of approximately 3% per day, which corresponded to a total difference of ~85% over the sampling period. Given our sample size, both trap types had the same limitations in their reliability to detect smaller changes in abundance trends.This first proof of concept demonstrated that AMTs depict large magnitude events such as phenological patterns just as well as conventional, lethal traps. Therefore, AMTs are a promising tool for future autonomous and non‐lethal monitoring, which paves the way for high temporal coverage and resolution in insect monitoring. However, this initial quantitative field test revealed that its long‐term applicability must be preceded by several adjustments to the image quality, power supply and to data transfer.

The high diversity of insects has limited the volume of long-term community data with a high taxonomic resolution and considerable geographic replications, especially in forests. Therefore, trends and causes of changes are poorly understood. Here we analyse trends in species richness, abundance and biomass of nocturnal macro moths in three quantitative data sets collected over four decades in forests in southern Germany. Two local data sets, one from coppiced oak forests and one from high oak forests included 125K and 48K specimens from 559 and 532 species, respectively. A third regional data set, representing all forest types in the temperate zone of central Europe comprised 735K specimens from 848 species. Generalized additive mixed models revealed temporal declines in species richness (−38%), abundance (−53%) and biomass (−57%) at the regional scale. These were more pronounced in plant host specialists and in dark coloured species. In contrast, the local coppiced oak forests showed an increase, in species richness (+62%), while the high oak forests showed no clear trends. Left and right censoring as well as cross validation confirmed the robustness of the analyses, which led to four conclusions. First, the decline in insects appears in hyper diverse insect groups in forests and affects species richness, abundance and biomass. Second, the pronounced decline in host specialists suggests habitat loss as an important driver of the observed decline. Third, the more severe decline in dark species might be an indication of global warming as a potential driver. Fourth, the trends in coppiced oak forests indicate that maintaining complex and diverse forest ecosystems through active management may be a promising conservation strategy in order to counteract negative trends in biodiversity, alongside rewilding approaches.

Wald ,Artenvielfalt ,Heterogenität ,ddc:577 - Abstract
How diversity of life is generated, maintained, and distributed across space and time is the central question of community ecology. Communities are shaped by three assembly processes: (I) dispersal, (II) environ-mental, and (III) interaction filtering. Heterogeneity in environmental conditions can alter these filtering processes, as it increases the available niche space, spatially partitions the resources, but also reduces the effective area available for individual species. Ultimately, heterogeneity thus shapes diversity. However, it is still unclear under which conditions heterogeneity has positive effects on diversity and under which condi-tions it has negative or no effects at all. In my thesis, I investigate how environmental heterogeneity affects the assembly and diversity of diverse species groups and whether these effects are mediated by species traits. In Chapter II, I first examine how much functional traits might inform about environmental filtering pro-cesses. Specifically, I examine to which extent body size and colour lightness, both of which are thought to reflect the species thermal preference, shape the distribution and abundance of two moth families along elevation. The results show, that assemblages of noctuid moths are more strongly driven by abiotic filters (elevation) and thus form distinct patterns in colour lightness and body size, while geometrid moths are driven by biotic filters (habitat availability), and show no decline in body size nor colour lightness along elevation. Thus, one and the same functional trait can have quite different effects on community assembly even between closely related taxonomic groups. In Chapter III, I elucidate how traits shift the relative importance of dispersal and environmental filtering in determining beta diversity between forests. Environmental filtering via forest heterogeneity had on aver-age higher independent effects than dispersal filtering within and among regions, suggesting that forest heterogeneity determines species turnover even at country-wide extents. However, the relative importance of dispersal filtering increased with decreasing dispersal ability of the species group. From the aspects of forest heterogeneity covered, variations in herb or tree species composition had overall stronger influence on the turnover of species than forest physiognomy. Again, this ratio was influenced by species traits, namely trophic position, and body size, which highlights the importance of ecological properties of a taxo-nomic group in community assembly. In Chapter IV, I assess whether such ecological properties ultimately determine the level of heterogeneity which maximizes species richness. Here, I considered several facets of heterogeneity in forests. Though the single facets of heterogeneity affected diverse species groups both in positive and negative ways, we could not identify any generalizable mechanism based on dispersal nor the trophic position of the species group which would dissolve these complex relationships. In Chapter V, I examine the effect of environmental heterogeneity of the diversity of traits itself to evalu-ate, whether the effects of environmental heterogeneity on species richness are truly based on increases in the number of niches. The results revealed that positive effects of heterogeneity on species richness are not necessarily based on an increased number of niches alone, but proposedly also on a spatially partition of resources or sheltering effects. While ecological diversity increased overall, there were also negative trends which indicate filtering effects via heterogeneity. In Chapter VI, I present novel methods in measuring plot-wise heterogeneity of forests across continental scales via Satellites. The study compares the performance of Sentinel-1 and LiDar-derived measurements in depicting forest structures and heterogeneity and to their predictive power in modelling diversity. Senti-nel-1 could match the performance of Lidar and shows high potential to assess free yet detailed infor-mation about forest structures in temporal resolutions for modelling the diversity of species. Overall, my thesis supports the notion that heterogeneity in environmental conditions is an important driv-er of beta-diversity, species richness, and ecological diversity. However, I could not identify any general-izable mechanism which direction and form this effect will have., Eine zentrale Frage in der Ökologie ist es, wie die Diversität von Artgemeinschaften generiert, aufrecht-erhalten, und über Zeit und Raum verteilt wird. Die Zusammensetzung von Artgemeinschaften wird durch drei Prozesse bestimmt, die einzelne Arten herausfiltern: (I) Ausbreitung, sowie (II) Umweltbedin-gungen und (III) Interaktionen mit anderen Arten. Heterogenität in Umweltbedingungen verändert das Zusammenspiel dieser Filterprozesse, da es die Anzahl verfügbarer Nischen erhöht und Ressourcen räum-lich aufteilt, aber auch den für die jeweilige Art verfügbaren Raum reduziert, was schlussendlich die Diver-sität der Artgemeinschaft beeinflusst. Es ist jedoch immer noch unklar, wann Heterogenität die Diversität positiv und wann negativ oder sogar überhaupt nicht beeinflusst. In dieser Dissertation werde ich der Fra-ge nachgehen, wie Heterogenität die Artzusammensetzung und Diversität verschiedenster Artengruppen beeinflusst und ob deren Reaktion auf Heterogenität durch Artmerkmale beeinflusst wird. In Kapitel II untersuche ich zunächst inwieweit funktionale Merkmale den Einfluss von Umweltbedingun-gen auf Arten widerspiegeln. Dazu untersuchte ich den Einfluss von Körpergröße und Helligkeit auf die Verbreitung und Abundanz zweier Nachtfalterfamilien entlang eines Höhengradienten. Es zeigte sich, dass Noctuidae stärker von abiotischen Filterprozessen, d.h. Höhe, betroffen waren und klare Zu- bzw. Ab-nahmen in Körpergröße und Helligkeit entlang der Höhe aufwiesen, während Geometridae eher von bioti-schen Filterprozessen, d.h. der Verfügbarkeit ihres Habitats, beeinflusst wurden und keine Merkmalsmus-ter entlang der Höhe aufwiesen. Entsprechend kann ein- und dasselbe Merkmal selbst innerhalb nah-verwandter Artgruppen unterschiedliche Effekte auf die Zusammensetzung von Arten haben. In Kapitel III erläutere ich, wie funktionelle Merkmale die relative Wichtigkeit von Ausbreitungs- und Umweltfiltern für beta-Diversität verschieben können. Sowohl innerhalb als auch zwischen den untersuch-ten Regionen beeinflusste Heterogenität in Wäldern die beta-Diversität stärker als die räumliche Distanz. Letztere wurde allerdings immer bedeutender, je schlechter die Ausbreitungsfähigkeit der jeweiligen Arten-gruppe war. Wenn die Heterogenität in Wäldern nach floristischen und strukturellen Aspekten aufgeteilt wird, so hatte erstere alles in allem einen stärkeren Einfluss auf Unterschiede zwischen Artgemeinschaften. Bei Artengruppen höheren trophischen Levels und größeren Körperbaus hatten die strukturellen Aspekte jedoch einen stärkeren Einfluss. Diese Ergebnisse verdeutlichen, dass die Artzusammensetzung von be-stimmte Merkmale beeinflusst werden kann. In Kapitel IV untersuche ich ob solche Merkmale das Level an Heterogenität festlegen, an welchen Arten-reichtum am höchsten ist. Dazu betrachtete ich mehrere Aspekte von Heterogenität in Wäldern. Obwohl Heterogenität in diesen Aspekten sowohl positive als auch negative Einfluss auf den Artenreichtum der verschiedensten Artengruppen hatte, konnten wir diese nicht anhand der Ausbreitungsfähigkeit oder des trophischen Levels der Artengruppen ableiten. In Kapitel V untersuche ich schließlich den Effekt von Heterogenität auf die Vielfalt von funktionalen Merkmalen. Dieser Ansatz soll helfen zu evaluieren, ob eventuelle Anstiege in der Artenzahl mit Hetero-genität einem Zuwachs in der Anzahl der ökologischen Nischen zurückzuführen sind. Die Ergebnisse legen nahe, dass ein Anstieg von Artenreichtum nicht dadurch beeinflusst wird, sondern auch durch ande-re Mechanismen wie die räumliche Aufteilung von Ressourcen oder durch die Schaffung von Zufluchts-räumen. Obwohl Heterogenität die ökologische Diversität überwiegend positiv beeinflusste, gab es auch einige negative Reaktionen die darauf hindeuten, dass Heterogenität auch bestimmte Merkmale aus einer Artgemeinschaft herausfiltern kann. In Kapitel VI präsentiere ich neue, Satelliten-gestützte Methoden in der Erfassung von Waldstrukturen. In dieser Studie werden die Eignung von LiDar (Lasergestützte Waldvermessungen aus der Luft) und Senti-nel-1 (Satellitenscan durch Radiowellen) verglichen, Waldstrukturen und deren Heterogenität zu messen sowie verschiedene Diversitäts-indices zu modellieren. Hierbei schnitt Sentinel-1 ähnlich gut ab wie LiDar. Somit zeigt Sentinel-1 großes Potential zukünftige Biodiversitätsaufnahmen zu unterstützen, auch aufgrund der kostenfreie Verfügbarkeit von Daten, deren globalen Abdeckung und hohen zeitlichen Auflösung. Insgesamt unterstützen die Ergebnisse meiner Arbeit die große Bedeutung von Heterogenität, insbesonde-re von Waldstrukturen, für beta-Diversität, Artenreichtum und funktionaler Diversität. Allerdings konnte keine generelle Regel identifiziert werden, nach der sich vorhersagen lassen würde welche genaue Richtung dieser Effekt haben wird.

- Abstract
The habitat heterogeneity hypothesis predicts that biodiversity increases with increasing habitat heterogeneity due to greater niche dimensionality. However, recent studies have reported that richness can decrease with high heterogeneity due to stochastic extinctions, creating trade-offs between area and heterogeneity. This suggests that greater complexity in heterogeneity–diversity relationships (HDRs) may exist, with potential for group-specific responses to different facets of heterogeneity that may only be partitioned out by a simultaneous test of HDRs of several species groups and several facets of heterogeneity. Here, we systematically decompose habitat heterogeneity into six major facets on ~500 temperate forest plots across Germany and quantify biodiversity of 12 different species groups, including bats, birds, arthropods, fungi, lichens and plants, representing 2,600 species. Heterogeneity in horizontal and vertical forest structure underpinned most HDRs, followed by plant diversity, deadwood and topographic heterogeneity, but the relative importance varied even within the same trophic level. Among substantial HDRs, 53% increased monotonically, consistent with the classical habitat heterogeneity hypothesis but 21% were hump-shaped, 25% had a monotonically decreasing slope and 1% showed no clear pattern. Overall, we found no evidence of a single generalizable mechanism determining HDR patterns.

15. Life on land ,580 Plants (Botany) - Abstract
Recent progress in remote sensing provides much-needed, large-scale spatio-temporal information on habitat structures important for biodiversity conservation. Here we examine the potential of a newly launched satellite-borne radar system (Sentinel-1) to map the biodiversity of twelve taxa across five temperate forest regions in central Europe. We show that the sensitivity of radar to habitat structure is similar to that of airborne laser scanning (ALS), the current gold standard in the measurement of forest structure. Our models of different facets of biodiversity reveal that radar performs as well as ALS; median R² over twelve taxa by ALS and radar are 0.51 and 0.57 respectively for the first non-metric multidimensional scaling axes representing assemblage composition. We further demonstrate the promising predictive ability of radar-derived data with external validation based on the species composition of birds and saproxylic beetles. Establishing new area-wide biodiversity monitoring by remote sensing will require the coupling of radar data to stratified and standardized collected local species data.

- Abstract
Ecosystem functions and services are severely threatened by unprecedented global loss in biodiversity. To counteract these trends, it is essential to develop systems to monitor changes in biodiversity for planning, evaluating, and implementing conservation and mitigation actions. However, the implementation of monitoring systems suffers from a trade-off between grain (i.e., the level of detail), extent (i.e., the number of study sites), and temporal repetition. Here, we present an applied and realized networked sensor system for integrated biodiversity monitoring in the Nature 4.0 project as a solution to these challenges, which considers plants and animals not only as targets of investigation, but also as parts of the modular sensor network by carrying sensors. Our networked sensor system consists of three main closely interlinked components with a modular structure: sensors, data transmission, and data storage, which are integrated into pipelines for automated biodiversity monitoring. We present our own real-world examples of applications, share our experiences in operating them, and provide our collected open data. Our flexible, low-cost, and open-source solutions can be applied for monitoring individual and multiple terrestrial plants and animals as well as their interactions. Ultimately, our system can also be applied to area-wide ecosystem mapping tasks, thereby providing an exemplary cost-efficient and powerful solution for biodiversity monitoring. Building upon our experiences in the Nature 4.0 project, we identified ten key challenges that need to be addressed to better understand and counteract the ongoing loss of biodiversity using networked sensor systems. To tackle these challenges, interdisciplinary collaboration, additional research, and practical solutions are necessary to enhance the capability and applicability of networked sensor systems for researchers and practitioners, ultimately further helping to ensure the sustainable management of ecosystems and the provision of ecosystem services., (© 2023 The Authors.
