Streams in the Alsea and Nestucca Sub-Basins were characterized using suites of
habitat attributes at the pool and reach scales. These suites were analyzed using a
multivariate process with the Multiple Response Permutation Procedure (MRPP)
to...

Estuaries provide juvenile salmonids with highly productive feeding grounds,
refugia from tidal fluctuations and predators, and acclimation areas for smoltification.
However, these dynamic, fluctuating salinity environments may also be...

This study examined the distribution and behavior of adult spring chinook salmon
(Oncorhynchus tshawytscha) related to patterns of stream temperature and physical
habitat at channel unit, reach, and basin-wide spatial scales in both a wilderness...

Relations between the diversity of juvenile anadromous salmonids and pool features
were examined in a managed and a pristine watershed in Oregon during the summer of
1990. There were no differences (p>0.05) in pool depth, velocity or pool wood...
