Phys.com  April 27, 2023 The continuing decline in the diversity and biomass of insects and other arthropods has caused great concern not only among scientists, policymakers, and stakeholders. A major reason for this is that many ecosystem services depend on diverse insect communities. Despite numerous studies on the dynamics of insect communities their causes are still not fully understood. An international team of researchers (Switzerland, Germany) addressed the causes and consequences of population and diversity trends spanning 10 to 120 years aiming at a better mechanistic understanding of the observed dynamics. covering freshwater and terrestrial insect taxa across five biomes.
