Rivers support some of Earth's richest biodiversity and provide essential ecosystem services
to society, but they are often fragmented by barriers to free flow. In Europe, attempts to …

Rivers are basic natural resources supporting ecosystems and human societies, and the
health of rivers is crucial to the Earth's sustainable development. Under the profound …

Many freshwater fishes are imperilled globally, and there is a need for easily accessible,
contemporary ecological knowledge to guide management. This compendium contains …

Many fish species depend on migration for various parts of their life cycle. Well‐known
examples include diadromous fish such as salmon and eels that need both fresh water and …

Variation in river flow is a strong behavioural determinant for the movement of many
freshwater fish species and often is linked to key aspects of their life cycle. The alteration of …

Recent advancements in telemetry have redefined our ability to quantify the fine-scale
movements of aquatic animals and derive a mechanistic understanding of movement …

Barrier removal and fish pass construction are increasingly used as tools to restore river
connectivity and improve habitat quality, but the effectiveness of subcatchment-scale …

Water diversion and pollution are two pervasive stressors in river ecosystems that often co‐
occur. Individual effects of both stressors on basal resources available to stream …

Anthropogenic reductions in riverine connectivity can severely impede the migrations of
anadromous species. In fragmented rivers, successful migrations depend on the ability of …

For many freshwater and diadromous fishes, dams create a significant conservation
challenge by fragmenting migratory routes, modifying habitats and altering patterns of water …
