Winter ecology of juvenile coho salmon (Oncorhynchus kisutch) in modified and unmodified sections of a coastal stream

Creator:: Phillips, Stephen H. (Stephen Homes), 1957-
Abstract:: Natural and gabion modified habitats containing coho salmon (Oncorhynchus kisutch) were observed and measured seasonally in East Fork Lobster Creek, a fifth order stream in western Oregon. Coho salmon usually inhabited backwater and secondary channel pools in winter. Large wood debris complexes and undercut banks were the primary sources of...

When is bigger better? Early marine residence of middle and upper Columbia River spring Chinook salmon

Creator:: Tomaro, Londi M., Teel, David J., Peterson, William T., and Miller, Jessica A.
Abstract:: Early ocean residence is considered a critical period for juvenile salmon although specific survival mechanisms are often unidentified and may vary by species or life stage. Columbia River spring-run Chinook salmon Oncorhynchus tshawytscha abundance has declined dramatically since the early 1900s. To elucidate mechanisms of early marine survival, we tested...

Wavelet analysis : linking multi-scalar pattern detection to ecological monitoring

Creator:: Anthony, Jill Ada Marie
Abstract:: Wavelet analysis is an analytical and modeling tool for optimizing sampling efficiency and accuracy, particularly in the context of designing long-term, large-scale monitoring plans. As a pattern analysis method that accommodates and preserves non-stationarity, wavelet analysis provides novel visualization and analytical capabilities for increased insight into interactions between multi-scalar heterogeneous...

Virulence characteristics of infectious pancreatic necrosis virus (IPNV) in brook trout, Salvelinus fontinalis, fry

Creator:: Maret, Joseph J.
Abstract:: Infectious pancreatic necrosis (IPN) is an acute, contagious disease of trout fry and fingerlings caused by viruses of the family birnaviridae. IPN disease usually results in mortality that is inversely proportional to the age of the fish. While many studies have been carried out to increase our understanding of IPN,...

Vegetation response to prescribed fire in mountain big sagebrush ecosystems at Lava Beds National Monument, California

Creator:: Ellsworth, Lisa M.
Abstract:: Anthropogenic land use alterations such as livestock grazing and fire suppression have greatly altered sagebrush grasslands of the Great Basin, facilitating invasion of exotic annuals, increases in woody species, and losses of native species. Much of the current research surrounding wildland and prescribed fire in sagebrush dominated ecosystems has focused...

Vegetation and Small Mammal Responses to Western Juniper (Juniperus occidentalis) Control in Eastern Oregon

Creator:: Morozumi, Corinne N.
Abstract:: Shrub-steppe ecosystems of western North America provide habitat for many wildlife species, are important components of public and private rangelands, and offer recreational opportunities for millions of people. They are some of the most vulnerable ecosystems in the United States and have been altered by human activities such as livestock...

Variability in expression of anadromy by female Oncorhynchus mykiss within a river network

Creator:: Mills, Justin S., Dunham, Jason B., Reeves, Gordon H., McMillan, John R., Zimmerman, Christian E., and Jordan, Chris E.
Abstract:: We described and predicted spatial variation in marine migration (anadromy) of female Oncorhynchus mykiss in the John Day River watershed, Oregon. We collected 149 juvenile O. mykiss across 72 sites and identified locations used by anadromous females by assigning maternal origin (anadromous versus non-anadromous) to each juvenile. These assignments used...

Utilizing Fishermen Knowledge and Expertise: Keys to Success for Collaborative Fisheries Research

Creator:: Yochum, Noelle, Starr, Richard M., and Wendt, Dean E.
Abstract:: Collaborative fisheries research provides a mechanism for integrating the unique knowledge, experience, and skills of fishermen and scientists. It is a joint intellectual endeavor that begins with the inception of a project and continues until its final stages, with each group having mutual investment in-and ownership of-the project. Collaborative fisheries...
