In the warming Arctic, aquatic habitats are in flux and salmon are exploring their options.
Adult Pacific salmon, including sockeye (Oncorhynchus nerka), coho (O. kisutch), Chinook …

Winter is an ecologically challenging season for ectothermic cold-water fish in natural
streams because of reduced flow and freezing. Hydropower regulation in many northern …

Stream-dwelling fish face highly-variable environmental conditions from fall to winter due to
fluctuations in water temperatures, discharge, and ice conditions. We provide an in-depth …

Robust estimates of survival and movement are important for informing the recovery of fish
populations as well as for the study of life history, behavior, and population ecology. We …

Many rivers and streams experience pronounced ice dynamics caused by the formation of
anchor and frazil ice, leading to flooding and disturbance of riparian and aquatic …

ABSTRACT The Long-term Aquatic Monitoring Protocols for New and Upgraded
Hydroelectric Projects identify suitable methods to evaluate the effectiveness of mitigation …

Atlantic salmon deposit their eggs in fresh water. Some individuals, predominantly male fish,
may then complete their life cycle in fresh water but most individuals migrate to sea before …

This study presents an experimental analysis of the effects of midwinter flow reduction (50–
75%, reduction in discharge in 4 h daily pulses) on the physical habitat and on behaviour …

In the seasonal climates of northern Europe and North America, water temperature
variations are ecologically challenging for aquatic organisms in natural streams. In winter …

Understanding of the winter ecology of stream salmonids is biased by research conducted in
northern temperate and boreal regions dominated by hard rock geology. Such systems are …
