White-breasted nuthatch density and nesting ecology in oak woodlands of the Willamette Valley, Oregon

Creator:: Viste-Sparkman, Karen
Abstract:: Habitat loss causes a reduction in available resources for wildlife, alters the configuration of remaining habitat, and may isolate wildlife populations. White-breasted nuthatches (Sitta carolinensis) are experiencing long-term population declines in the Willamette Valley of Oregon, where they are historically associated with oak woodlands. As secondary cavity-nesters, white-breasted nuthatches may...

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...

Using parasite community data and population genetics for assessing Pacific sardine (Sardinops sagax) population structure along the west coast of North America

Creator:: Baldwin, Rebecca E. B.
Abstract:: Pacific sardines (Sardinops sagax) are an economically and ecologically important forage fish which transfer energy from planktonic primary producers and secondary consumers to upper trophic predators. Previous genetics studies of Pacific sardine suggested a panmictic population with a shallow genetic structure. However, more than one subpopulation within the Central California...

Using DNA Metabarcoding to Study Interactions Between Native Bees and Plants: Technical Developments and Applications

Creator:: Arstingstall, Katherine A.
Abstract:: Pollination is an essential ecosystem service that sustains functioning ecosystems and aids in food production. In response to recent, widespread declines of managed and native bee populations, many land managers have shown interest in developing conservation and restoration plans for enhancing native bee habitat. However, there is a lack of...

Trophically transmitted parasites as ecosystem indicators : relationships among parasite community structure, juvenile salmon diet composition, and ocean conditions

Creator:: Losee, James P.
Abstract:: Recent research conducted throughout the Northern California Current (NCC) on the ecology of Pacific salmon (Oncorhynchus spp.) indicates that variable ocean conditions affect the community composition of zooplankton in the nearshore environment which, in turn, can affect the quality of prey for fish, sea birds and mammals. Interannual variability in...

Translocating Adult Pacific Lamprey within the Columbia River Basin: State of the Science

Creator:: Ward, David L., Clemens, Benjamin J., Clugston, David, Jackson, Aaron D., Moser, Mary L., Peery, Chris, and Statler, David P.
Abstract:: The Pacific lamprey (Entosphenus tridentatus) is in decline in the Columbia River Basin, and translocating adult lamprey to bypass difficult migration corridors has been implemented since 2000. We describe and report results from two current translocation programs, provide context for use of translocation, and discuss potential benefits, risks, and uncertainties....

Transferrin variation and population differentiation in black-tailed deer

Creator:: Chinn, Edwin Kan Kit
Abstract:: Transferrin of Columbian black-tailed deer (Odocoileus hemionus columbianus) displayed two types of polymorphism. One type involved differences in sialic acid content. The nature of the other polymorphism is not known. A hypothesis for three codominant alleles at a common locus was proposed and tested by using the Hardy-Weinberg Principle. The...

Tide gates in the Pacific Northwest : operation, types, and environmental effects

Creator:: Giannico, Guillermo and Souder, Jon A.
Abstract:: This report is an attempt to address some critical information gaps regarding the effects of dikes and tide gates on coastal ecosystems and fisheries resources. The authors have identified the information needs during their work with landowners, community organizations, and resource management agencies and through a compilation and summary of...
