Long-term stability of ecological communities is vital for maintaining ecosystem functioning. Here, Blüthgen et al. show that greater land-use intensity in grasslands and forests can have negative impacts on the stability of plant and animal communities, driven primarily by variation in asynchrony between species.

Analysis of a large grassland biodiversity dataset shows that increases in local land-use intensity cause biotic homogenization at landscape scale across microbial, plant and animal groups, both above- and belowground, that is largely independent of changes in local diversity.

Although co-occurring species may differ widely in their response traits, coordinated functional trait shifts may emerge at the community level in response to environmental factors. Here, the authors use data from 150 grassland sites to identify a coordinated slow-fast strategy response to land-use intensification across above- and belowground taxa.

Agricultural intensification may negatively impact biodiversity via a number of mechanisms. Here, Gámez-Virués et al.show that landscape simplification acts as an environmental filter to homogenise grassland arthropod communities into pools of species with less specialised functional traits.

Predicting species responses to climate change may be complicated by the influence of other factors. Here, the authors report that warming is linked to terrestrial and freshwater community shifts towards warm-adapted species overall, but body size, thermal niche breadth, species richness and baseline temperature modulate the trends.

Aquatic (blue) and terrestrial (green) food webs are part of the same landscape, but it remains unclear whether they respond similarly to shared environmental gradients. Using long-term monitoring data from Switzerland and a metaweb approach, this study reveals how inferred blue and green food webs exhibit different properties along an elevation gradient and among land-use types.

Land use intensification is a major driver of biodiversity change. Here the authors measure diversity across multiple trophic levels in agricultural grassland landscapes of varying management, finding decoupled responses of above- and belowground taxa to local factors and a strong impact of landscape-level land use.

The authors test whether spatial scale (plot, local and landscape) affects the supply of various ecosystem services in grasslands, finding that some services are predicted by plot-level properties while others depend more on landscape-level management.

Simulating extinctions across regional food webs reveals that losing species from one habitat— especially wetlands—can cascade to others, accelerating multi-habitat food web collapse, highlighting the need for integrated conservation strategies.

Analyses of a dataset of arthropod biomass, abundance and diversity in grassland and forest habitats in Germany for the period 2008–2017 reveal that drivers of arthropod declines act at the landscape level.

Satellite-borne radar systems are promising tools to obtain spatial habitat data with complete geographic coverage. Here the authors show that freely available Sentinel-1 radar data perform as well as standard airborne laser scanning data for mapping biodiversity of 12 taxa across temperate forests in Germany.

Multi-year field experiments across six continents suggest that insects have an important contribution to decomposition and carbon release from forest deadwood.

Managing forests for the supply of multiple ecosystem services (ES) is key given potential trade-offs among services. Here, the authors analyse how forest stand attributes generate trade-offs among ES and the relative contribution of forest attributes and environmental factors to predict services.

Drivers of long-term trends in insect populations are usually inferred from space-for-time substitution studies rather than from time-series data. Here, the authors investigate insect trends across a 40-year period in Switzerland and test their linkages with climate change, land use change and their interactions.

An analysis across multiple species groups and different facets of stand-level heterogeneity in temperate forests from Central Europe reveals that heterogeneity–diversity relationships are not generalizable and predictable as modelling approaches suggest, varying even between ecologically similar species groups.

Both a high number of species and abundance in multiple trophic levels are required for ecosystems to continue to provide the services humans require of them.

Species richness and biomass of insects has declined on average across 140 forest sites sampled over a decade in Germany, with larger, more abundant, and carnivorous species found to be more susceptible to decline.
