Recovery and Degradation Drive Changes in the Dispersal Capacity of Stream Macroinvertebrate Communities. [PDF]
Freshwater ecosystems across Europe are recovering unevenly despite restoration efforts, partly due to the limited ability of many species to disperse. Using a dataset of over 1300 time series, we found that improved ecological quality often leads to gains in macroinvertebrate species with strong dispersal capacities, while degrading sites lose these ...

Complex and nonlinear climate‐driven changes in freshwater insect communities over 42 years
Abstract The ongoing biodiversity crisis becomes evident in the widely observed decline in abundance and diversity of species, profound changes in community structure, and shifts in species’ phenology. Insects are among the most affected groups, with documented decreases in abundance up to 76% in the last 25–30 years in some terrestrial ecosystems ...
