Urbanization has dramatically destabilized crucial ecosystem functions through extensive land‐use changes, habitat fragmentation, and modified species compositions. However, the mechanisms through which urbanization affects river ecosystem multifunctionality (EMF)—the simultaneous performance of multiple ecosystem functions—remain largely unknown. This study evaluated the impact of urbanization on EMF using macroinvertebrate c...

Human disturbance is a major threat to natural ecosystems globally. However, how disturbances alter the interplay of deterministic and stochastic processes underlying community structure and diversity remains to be clarified, as evidence from natural systems is particularly lacking. Here, we investigated how the taxonomic, functional, and phylogenetic α and β diversity of aquatic insects respond to a gradient of cumulative hum...

The holarctic genus Mesenchytraeus is one of the species‐rich genera in the family Enchytraeidae. Changbai Mountain supports high diversity of Mesenchytraeus species, making it an ideal area to explore species boundaries. We explored species boundaries of Mesenchytraeus using an integrative approach. Morphological taxonomy recognized 10 species in this region, five of them new to science. In contrast, molecular species delimit...
