(2011-07-25)Juvenile salmonids display highly variable spatial and temporal movement patterns that are influenced by density dependent (e.g., competition, predation) and density independent (e.g., genetics, stream discharge, physica ...
-
(American Fisheries Society, 2006-05)A recent trend of enhancing freshwater emergent wetlands for waterfowl and other wildlife has raised concern about the effects of such measures on juvenile salmonids. We undertook this study to quantify the degree and ex ...
-
(2010-04-22)Despite evidence that juvenile Chinook salmon (Oncorhynchus tshawytscha) utilize North Pacific estuaries for growth and salinity acclimation, research in the Columbia River estuary has lead to opposing hypotheses about t ...

-
(2013-05-03)I conducted a study to identify potential spawning habitat for anadromous salmonids above a 60-year-old hydropower dam in the headwaters of the North Umpqua River in Oregon. Like many other historical salmonid-bearing ri ...
-
(Governor's Natural Resources Office, 1999-09-08)The forests of Oregon are an important part of the landscape used by wild salmonids. How these forests are managed is important in attaining the goals of the Oregon Plan for Salmon and Watersheds (Oregon Plan) and Orego ...
-
(Oregon Watershed Enhancement Board, 2002-07-15)This report discusses major characteristics of western Oregon’s lowland rivers, streams, and estuaries that the IMST finds to be important to wild salmonids. IMST describes how landscape scale factors (landscape structur ...
