Abstract Recently reported insect declines have raised both political and social concern. Although the been attributed to land use climate change, supporting evidence suffers from low taxonomic resolution, short time series, a focus on local scales, collinearity of identified drivers. In this study, we conducted systematic assessment populations in southern Germany, which showed that differences biomass richness are highly context dependent. We found largest difference between semi-natural...
ABSTRACT Among the many concerns for biodiversity in Anthropocene, recent reports of flying insect loss are particularly alarming, given their importance as pollinators, pest control agents, and a food source. Few monitoring programmes cover large spatial scales required to provide more generalizable estimates responses global change drivers. We ask how climate surrounding habitat affect biomass using data from first year new network at 84 locations across Germany comprising gradient land...
Changes in climate and land use are major threats to pollinating insects, an essential functional group. Here, we unravel the largely unknown interactive effects of both on seven pollinator taxa using a multiscale space-for-time approach across large land-use gradients temperate region. Pollinator community composition, regional gamma diversity, dissimilarity (beta diversity) were shaped by climate-land-use interactions, while local alpha diversity was solely explained their additive...
Abstract Enhancing the diversity of mass‐flowering crops (i.e. crop diversity) in agricultural landscapes is often proposed as a measure to favour pollinators and pollination, but it uncertain whether enhances pollinator richness on wide landscape level. Here, we surveyed communities semi‐natural habitats throughout whole growing season 26 examine how temporal spatial heterogeneity support species richness. Crop was unrelated wider landscape, were equally important determining Surprisingly,...
Arthropods respond to vegetation in multiple ways since plants provide habitat and food resources indicate local abiotic conditions. However, the relative importance of these factors for arthropod assemblages is less well understood. We aimed disentangle effects plant species composition environmental drivers on taxonomic assess which aspects contribute relationships between assemblages. In a multi-scale field study Southern Germany, we sampled vascular terrestrial arthropods typical...
Abstract To understand how plant–pollinator interactions respond to habitat fragmentation, we need novel approaches that can capture properties emerge at broad scales, where multiple communities engage in metanetworks. Here studied over 2 years on 29 calcareous grassland fragments selected along independent gradients of size and surrounding landscape diversity cover types. We associated network centrality with their ecological traits, respectively. Interactions involving specialist plants...
The massive declines in terrestrial arthropods reported across Europe call for effective methods to monitor and promote biodiversity human-dominated landscapes. Previous studies vary their support the suitability of plants as indicators arthropod diversity, while potential subsets conservation-relevant plant species estimate richness remains be tested. Moreover, relative importance compared other factors driving richness, such land-use intensity, habitat amount landscape configuration, is...
The use of metabarcoding for insect species identification has grown rapidly, but the absence abundance data hinders meaningful diversity metrics like sample coverage-standardized richness. Additionally, vast number taxa often lacks a unified phylogeny or trait database. We present framework constructing phylogenetic tree encompassing majority families, standardisation coverage (an objective measure completeness) and assessment both taxonomic using Hill series data. Applied to central...
Abstract To increase pollinator populations, international policy targets minimum levels of seminatural habitat cover, but it is unknown whether improving the quality existing habitats could bring similar benefits without need reducing cropland area. Using data we collected in 26 Italian agricultural landscapes during entire flying season, explored relative importance quantity (seminatural cover) and (flower availability) on densities habitats. We obtained transect‐based counts estimated...
Abstract Climate and land‐use change are key drivers of environmental degradation in the Anthropocene, but too little is known about their interactive effects on biodiversity ecosystem services. Long‐term data trends currently lacking. Furthermore, previous ecological studies have rarely considered climate land use a joint design, did not achieve variable independence or lost statistical power by covering full range gradients. Here, we introduce multi‐scale space‐for‐time study design to...
Understanding the organization of mutualistic networks at multiple spatial scales is key to ensure biological conservation and functionality in human-modified ecosystems. Yet, how changing habitat landscape features affect pollen-bee interaction still poorly understood. Here, we analysed bee-flower visitation bee-pollen-transport interactions respond fragmentation local network regional metanetwork scales, combining data from 29 fragments calcareous grasslands, an endangered biodiversity...
Abstract Land-use intensification and climate change threaten ecosystem functions. A fundamental, yet often overlooked, function is decomposition of necromass. The direct indirect anthropogenic effects on decomposition, however, are poorly understood. We measured two contrasting types necromass, rat carrion bison dung, 179 study sites in Central Europe across an elevational gradient 168–1122 m a.s.l. within both local regional land uses. Local land-use included forest, grassland, arable...
Climate and land use are major determinants of biodiversity, declines in species richness cold human exploited landscapes can be caused by lower rates biotic interactions. Deadwood fungi bacteria interact strongly with their hosts due to long‐lasting evolutionary trajectories. However, how interactions (specialization) change temperature land‐use intensity unknown for both microbial groups. We hypothesize a decrease specialization communities decreasing increasing while controlling...
Higher temperatures can increase metabolic rates and carbon demands of invertebrate herbivores, which may shift leaf-chewing herbivory among plant functional groups differing in C:N (carbon:nitrogen) ratios. Biotic factors influencing herbivore species richness modulate these temperature effects. Yet, systematic studies comparing different habitats landscapes along gradients are lacking. This study was conducted on 80 plots covering large temperature, land use Bavaria, Germany. We...
<title>Abstract</title> Global biodiversity decline with increasing land-use intensity is supposedly linked to the homogenization of species communities across landscapes. However, contribution landscape insect diversity loss still largely untested. We compared an indicator for community homogenization, distance decay slope between four local habitats intensity, from forests managed grasslands, arable lands and settlements, imbedded in near-natural, agricultural urban regions. This...
Contemporary climate change leads to earlier spring phenological events in Europe. In forests, which overstory strongly regulates the microclimate beneath, it is not clear if further equally shifts timing of leaf unfolding for over- and understory main deciduous forest species, such as Fagus sylvatica L. (European beech). Furthermore, known yet how this vertical (mis)match—the difference between understory—affects remotely sensed satellite signal. To investigate this, we disentangled start...
Arthropod predators are important for ecosystem functioning by providing top-down regulation of insect herbivores. As predator communities and activity influenced biotic abiotic factors on different spatial scales, the strength ('arthropod predation') is also likely to vary. Understanding combined effects potential drivers arthropod predation urgently needed with regard anthropogenic climate land-use change. In a large-scale study, we recorded rates using artificial caterpillars 113 plots...

European roe deer (Capreolus capreolus L.) are important given their economic, recreational and ecological value. However, uncontrolled numbers can result in negative impacts on forest regeneration agricultural crops, disease transmission occurrences of deer-vehicle collisions. Information the abundance distribution is needed for effective management. We combined distance sampling (DS) dung pellet groups with multiple variables to develop a density surface model (DSM) federal state Bavaria...
Urbanization and agricultural intensification are considered the main causes of recent insect decline in temperate Europe, while direct climate warming effects still ambiguous. Nonetheless, higher temperatures advance spring leaf emergence, which turn may directly or indirectly affect insects. We therefore investigated how Sentinel-2-derived start season (SOS) its spatial variability (SV-SOS) affected by temperature whether these green-up variables can explain biomass richness across a...
Abstract Dung beetles are important actors in the self‐regulation of ecosystems by driving nutrient cycling, bioturbation, and pest suppression. Urbanization sprawl agricultural areas, however, destroy natural habitats may threaten dung beetle diversity. In addition, climate change cause shifts geographical distribution community composition. We used a space‐for‐time approach to test effects land use on α‐diversity, local specialization ( H 2 ′) resources, γ‐diversity dung‐visiting beetles....
Abstract Global warming can increase insect pest pressure by enhancing reproductive rates. Whether this translates into yield losses depends on phenological synchronisation of pests with their host plants and natural enemies. Simultaneously, landscape composition may mitigate climate effects shaping the resource availability for antagonists. Here, we study combined temperature abundances, larval parasitism, crop damage yield, while also considering phenology, to identify strategies...

Abstract Interactions between plants and herbivorous invertebrates drive the nutritional quality of resources for higher trophic levels, nutrient cycling plant-community structure. Thereby, shifts in functional composition plant communities particularly impact ecosystem processes. However, current understanding herbivory is limited concerning climate, land use richness, as comparative studies different groups are lacking. This study was conducted on 81 plots covering large climatic land-use...
