This study examines the effects of flow intermittency and light pollution on macroinvertebrates in river networks, showing that combined stressors have stronger downstream impacts.

The paper compiles a thermal tolerance database for freshwater fish and invertebrates, including 5000+ records from 800+ species, to assess thermal risks under current and future environmental conditions.

This study investigates how salinity affects thermal tolerance in aquatic organisms through a meta-analysis of 90 publications, finding that lower salinity increases lower temperature limits and decreases upper limits across most groups.

The paper tests the Asymmetric Response Concept by modeling how stream food webs respond to multiple stressors and their release, finding that temperature has stronger impacts than salt and that community and ecosystem responses differ.

The paper quantifies how six riverine organism groups respond to seven anthropogenic stressors using meta-analysis across 143 datasets.
