Temperature is one of the most important environmental factors controlling the distribution and behavior of fishes. Fish often inhabit a specific thermal niche where they optimize physiological performance. Although water temperature requirements and preferences vary according to individual species and life stage, of interest and relevance to us is continual engagement in field...
Preserving water quality is one purpose of every National Wildlife Refuge in Alaska. Land cover and use can affect the water quality of rivers, lakes and other surface waters. Potential sources of point- and non point-source pollution, such as communities and resource development projects, can threaten refuges' waters.
