The study focuses on the diversity of urban channel chironomids (the Aa River, the City of Münster, North‐western Germany), initially intended as a proxy of habitat structure. Three ecological key points marked the study:
The channel is the discharge effluent of a eutrophic lake.
It includes lotic and lentic sections.
Runoff variability is high (0.02 to 4 m3 s−2).
Chironomid pupal exuviae were sampled...
Temporary rivers are increasingly common freshwater ecosystems, but there have been no global syntheses of their community patterns. In this study, we examined the responses of aquatic invertebrate communities to flow intermittence in 14 rivers from multiple biogeographic regions covering a wide range of flow intermittence and spatial arrangements of perennial and temporary reaches. Hydrological data...
