Insect biomass shows a stronger decrease than species richness along urban gradients

1. Anthropogenic land cover change is a major driver of biodiversity loss, with urbanisation and farmland practices responsible for some of the most drastic modifications of natural habitats. The relative importance of different land covers for shaping insect communities, however, is unclear. 2. This…

Large‐scale spatial variability in urban tolerance of birds

Quantifying intraspecific and interspecific trait variability is critical to our understanding of biogeography, ecology and conservation. But quantifying such variability and understanding the importance of intraspecific and interspecific variability remain challenging. This is especially true of large…

Winners and losers over 35 years of dragonfly and damselfly distributional change in Germany

Abstract Aim Recent studies suggest insect declines in parts of Europe; however, the generality of these trends across different taxa and regions remains unclear. Standardized data are not available to assess large‐scale, long‐term changes for most insect groups but opportunistic citizen science data…

Thermal flexibility and a generalist life history promote urban affinity in butterflies

Urban expansion poses a serious threat to biodiversity. Given that the expected area of urban land cover is predicted to increase by 2–3 million km 2 by 2050, urban environments are one of the most widespread human‐dominated land‐uses affecting biodiversity. Responses to urbanization differ greatly among…

Revisiting global trends in freshwater insect biodiversity : A reply

Abstract Jähnig et al. make some useful points regarding the conclusions that can be drawn from our meta‐analysis; however, some issues require clarification. First, we never suggested that there was a globally increasing trend of freshwater insect abundances, but only spoke of an average increasing…

Widespread decline in Central European plant diversity across six decades

Abstract Based on plant occurrence data covering all parts of Germany, we investigated changes in the distribution of 2136 plant species between 1960 and 2017. We analyzed 29 million occurrence records over an area of ~350,000 km 2 on a 5 × 5 km grid using temporal and spatiotemporal models and accounting…

Mapping human pressures on biodiversity across the planet uncovers anthropogenic threat complexes

Abstrakt Der Klimawandel und andere anthropogene Faktoren, die die biologische Vielfalt verändern, betreffen nicht alle Teile der Erde in gleicher Weise. Während unsere Kenntnisse zu jedem einzelnen Gefährdungsfaktor ständig wachsen, ist unser Verständnis zu den räumlichen Beziehungen zwischen den verschiedenen…
