Abstract Global change, especially land‐use intensification, affects human well‐being by impacting the delivery of multiple ecosystem services (multifunctionality). However, whether biodiversity loss is a major component global change effects on multifunctionality in real‐world ecosystems, as experimental ones, remains unclear. Therefore, we assessed biodiversity, functional composition and 14 150 agricultural grasslands differing intensity. We also introduce five measures which were...
Biodiversity loss can affect the viability of ecosystems by decreasing ability communities to respond environmental change and disturbances. Agricultural intensification is a major driver biodiversity has multiple components operating at different spatial scales: from in-field management intensity landscape-scale simplification. Here we show that landscape-level effects dominate functional community composition even buffer on homogenization, animal in real-world managed landscapes unified...
Significance Land-use intensification is a major threat to biodiversity. So far, however, studies on biodiversity impacts of land-use intensity (LUI) have been limited single or few groups organisms and not considered temporal variation in LUI. Therefore, we examined total ecosystem grasslands varying LUI with newly developed index called multidiversity, which integrates the species richness 49 different organism ranging from bacteria birds. Multidiversity declined strongly increasing LUI,...
Abstract Impacts of climate change on individual species are increasingly well documented, but we lack understanding how these effects propagate through ecological communities. Here combine distribution models with network analyses to test potential impacts >700 plant and animal in pollination seed-dispersal networks from central Europe. We discover that interact a low diversity have narrow climatic niches most vulnerable change. In contrast, biotic specialization plants is not related...
Abstract Land-use intensification is a major driver of biodiversity loss. However, understanding how different components land use drive loss requires the investigation multiple trophic levels across spatial scales. Using data from 150 agricultural grasslands in central Europe, we assess influence local- and landscape-level on more than 4,000 above- belowground taxa, spanning 20 groups. Plot-level land-use intensity strongly negatively associated with aboveground groups, but positively or...
Land use is known to reduce the diversity of species and complexity biotic interactions. In theory, interaction networks can be used predict sensitivity against co-extinction, but this has rarely been applied real ecosystems facing variable land-use impacts. We investigated plant-pollinator on 119 grasslands that varied quantitatively in management regime, yielding 25401 visits by 741 pollinator 166 plant species. Species-specific responses land were significantly predicted weighted average...
Species diversity promotes the delivery of multiple ecosystem functions (multifunctionality). However, relative functional importance rare and common species in driving biodiversity–multifunctionality relationship remains unknown. We studied between (according to their local abundances across nine different trophic groups), multifunctionality indices derived from 14 on 150 grasslands a land-use intensity (LUI) gradient. The above- below-ground had opposite effects, with above-ground being...
Land‐use intensification is a key driver of biodiversity change. However, little known about how it alters relationships between the diversities different taxonomic groups, which are often correlated due to shared environmental drivers and trophic interactions. Using data from 150 grassland sites, we examined land‐use (increased fertilization, higher livestock densities, increased mowing frequency) altered correlations species richness 15 plant, invertebrate, vertebrate taxa. We found that...
Abstract Rapid growth of the world's human population has increased pressure on landscapes to deliver high levels multiple ecosystem services, including food and fibre production, carbon storage, biodiversity conservation, recreation. However, we currently lack general principles describing how achieve this landscape multifunctionality. We combine theoretical simulations empirical data 14 services measured across 150 grasslands in three German regions. In doing so, investigate circumstances...
A growing number of offshore wind farms have led to a tremendous increase in artificial lighting the marine environment. This study disentangles connection light characteristics, which potentially influence reaction nocturnally migrating passerines illumination under different cloud cover conditions. In spotlight experiment on North Sea island, birds were exposed combinations colour (red, yellow, green, blue, white), intensity (half, full) and blinking mode (intermittent, continuous) while...
Summary When entomophilous plants are introduced to a new region, they may leave behind their usual pollinators. In particular, plant species with specialized pollination then be less likely establish and spread (i.e. become invasive). Moreover, other reproductive characteristics such as self‐compatibility flowering duration also affect invasion success. Here, we specifically asked whether species' specialization towards pollinator families, respectively, measured in the native range,...
Plant strategies frequently vary from opportunistic pollination to specialization single pollinators within the same community. Unraveling proximate mechanisms that determine degree of plant generalization has become a primary goal ecology. Color signaling is potentially important mechanism because it well established many use color stimuli locate food items. Until now, studies on importance in structuring networks have not considered floral coloration as perceived by pollinators. Here, we...
