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...
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,...
Significance Ecosystem services derive from ecosystem functions and rely on complex interactions among a diversity of organisms. By understanding the relationships between biodiversity, functions, humans receive nature, we can anticipate how changes in land use will affect ecosystems human wellbeing. We show that increasing land-use intensity homogenizes synergies three organizational levels ecosystem, namely, services. Increasing keystone components, which are important for functioning...
Summary Recent declines in biodiversity have given new urgency to questions about the relationship between land‐use change, and ecosystem processes. Despite existence of a large body research on effects land use species richness, it is unclear whether richness are principally direct or indirect, mediated by concomitant changes Therefore, we compared (fertilization, mowing grazing) with indirect ones (mediated via grassland productivity) for grasslands central Europe. We measured above‐ground...
Abstract Aims Vegetation‐plot records provide information on the presence and cover or abundance of plants co‐occurring in same community. data are spread across research groups, environmental agencies biodiversity centers and, thus, rarely accessible at continental global scales. Here we present sPlot database, which collates vegetation plots worldwide to allow for exploration patterns taxonomic, functional phylogenetic diversity plant community level. Results version 2.1 contains from...
Grazing represents the most extensive use of land worldwide. Yet its impacts on ecosystem services remain uncertain because pervasive interactions between grazing pressure, climate, soil properties, and biodiversity may occur but have never been addressed simultaneously. Using a standardized survey at 98 sites across six continents, we show that soil, are critical to explain delivery fundamental drylands Increasing pressure reduced service in warmer species-poor drylands, whereas positive...
Abstract Aim Global‐scale maps of the environment are an important source information for researchers and decision makers. Often, these created by training machine learning algorithms on field‐sampled reference data using remote sensing as predictors. Since field samples often sparse clustered in geographic space, model prediction requires a transfer trained to regions where no available. However, recent studies question feasibility predictions far beyond location data. Innovation We propose...
Abstract Organismal functional strategies form a continuum from slow- to fast-growing organisms, in response common drivers such as resource availability and disturbance. However, whether there is synchronisation of these at the entire community level unclear. Here, we combine trait data for >2800 above- belowground taxa 14 trophic guilds spanning disturbance gradient German grasslands. The results indicate that most consistently respond through both direct trophically mediated effects,...
Abstract. In previous studies, limited dispersal was revealed to be the main obstacle restoration of species‐rich flood‐meadows along northern Upper Rhine in Germany. To overcome limitation we transferred freshly mown plant material from sources a site on former arable field. Before application, topsoil removed accelerate nutrient impoverishment and create favourable conditions for seedling recruitment. Topsoil removal led drastic reduction organic matter essential mineral nutrients level...
Abstract Human land use may detrimentally affect biodiversity, yet long-term stability of species communities is vital for maintaining ecosystem functioning. Community can be achieved by higher diversity (portfolio effect), asynchrony across (insurance hypothesis) and abundance populations. However, the relative importance these stabilizing pathways whether they interact with in real-world ecosystems unknown. We monitored inter-annual fluctuations 2,671 plant, arthropod, bird bat 300 sites...
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...
Abstract Persecution and overexploitation by humans are major causes of species extinctions. Rare species, often confined to small geographic ranges, usually at highest risk, whereas extinctions superabundant with very large ranges rare. The Yellow‐breasted Bunting (Emberiza aureola) used be one the most abundant songbirds Palearctic, a breeding range stretching from Scandinavia Russian Far East. Anecdotal information about rapid population declines across caused concern unsustainable...
Summary One of the key questions in ecosystem restoration is choice seed material for restoring plant communities. More and more scientists practitioners are currently advocating use regional sources, based on argument that plants often adapted to local or environmental conditions, thus, sources should provide best success. However, there still substantial debate about this approach, partly because a lack solid empirical data. We conducted multispecies transplant experiment which we compared...
Summary Ecological restoration of grasslands is increasingly based on regional seeds derived from predefined seed transfer zones. However, the degree and spatial pattern genetic differentiation among provenances different zones largely unknown. We assessed eight out 22 German for seven common grassland species ( Arrhenatherum elatius, Centaurea jacea, Daucus carota, Galium album, Hypochaeris radicata, Knautia arvensis Lychnis flos‐cuculi ) using AFLP markers. analysed population structure...
