▪ Abstract Movement between discrete habitat patches can present significant challenges to
organisms. Freshwater invertebrates achieve dispersal using a variety of mechanisms that …

The effects of drought on stream invertebrates have been reviewed, but the effects of
artificially reduced flows have not. We addressed this knowledge gap by reviewing the …

Human appropriation of water resources may induce water stress in freshwater ecosystems
when ecosystem needs are not met. Intensive abstraction and regulation cause river …

Hydropower is often presented as a clean and renewable energy source that is
environmentally preferable to fossil fuels or nuclear power. Hydropower production …

Large dams have been constructed on rivers to meet human demands for water, electricity,
navigation, and recreation. As a consequence, flow and temperature regimes have been …

The hyporheic zone is a potential refuge that can promote persistence of benthic
invertebrates during adverse conditions in surface streams. For decades, changes in …

River flow regimes, controlled by climatic and catchment factors, vary over a wide range of
temporal and spatial scales. This hydrological dynamism is important in determining the …

The flow regime of a river is fundamental in determining its ecological characteristics.
Impoundment of rivers has been documented to severely impact the natural flow regime …

Flow regulation via impoundments threatens lotic ecosystems and the services they provide
globally. Impoundments drastically alter flow and stream temperature variability within fluvial …

Floods and low flows are hydrological events that influence river ecosystems, but few
studies have compared their relative importance in structuring invertebrate communities …
