Headwater stream macroinvertebrates of the H.J. Andrews Experimental Forest, Oregon

Creator:: Frady, Charles H.
Abstract:: Recent studies of headwater streams have demonstrated their importance to overall watershed biodiversity, nutrient cycling, and energy flux. However, little attention has been paid to long-term effects of forest harvest on macroinvertebrate communities in headwater streams. This study investigated headwater stream macroinvertebrate communities in the H.J. Andrews Experimental Forest, Oregon,...

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...

The range expansion of the northern barred owl : an evaluation of the impact on spotted owls

Creator:: Kelly, Elizabeth G.
Abstract:: Since their range expansion into the Pacific Northwest, anecdotal evidence suggests that northern barred owls (Strix varia varia) may be displacing northern spotted owls (Strix occidentalis caurina). My objectives were to characterize barred owl distribution and population increase in Oregon, investigate spotted owl territory performance before and after barred owl...

Annual Costs of Wild Salmon Restoration Efforts in the Columbia River Basin

Creator:: Rice, Robert J.
Abstract:: The goal of this project was to estimate the total annual cost of salmon recovery efforts throughout the Columbia River Basin from all stakeholders, including direct and indirect costs. How much is spent on salmon recovery efforts each year in the Columbia River Basin? Depending on who you ask, you...

An Investigation into the Distribution, Residency Patterns, Population Connectivity, and Abundance of Blue Whales (Balaenoptera musculus) in New Zealand

Creator:: Barlow, Dawn R.
Abstract:: Species conservation depends on robust population assessment. Data on population abundance, distribution, and connectivity are critical for effective management, especially as baseline information for newly documented populations. I describe a pygmy blue whale (Balaenoptera musculus brevicauda) population in New Zealand waters with year-round presence that overlaps with industrial activities. This...

Relative resistance of the Coho salmon (Oncorhynchus kisutch) and the Chinook salmon (Oncorhynchus tshawytscha) to the parasitic larvae (Glochidia) of the freshwater mussel (Margaritifera margaritifera)

Creator:: Fustish, Charles A.
Abstract:: The relative resistance of the coho salmon (Oncorhynchus kisutch) and the chinook salmon (O. tshawyscha) to the parasitic larvae (glochidia) of the freshwater mussel (Margaritifera margaritifera) was studied in an attempt to determine why the coho appeared to be more resistant. Natural and acquired antibody was sought in the mucus...

Salmon Management in Southeast Alaska: An Examination of Multi-Dimensional Management

Creator:: Chrittenden, Whitney L.
Abstract:: Pacific salmon are culturally and economically important species to Southeast Alaska, where there is a history of large wild runs and supplemental production from hatchery programs. Salmon management in Alaska is divided amongst various governmental agencies. Non-governmental organizations also play a pivotal role in salmon management. To fulfill the requirements...

Influence of biologically stabilized kraft mill effluent on the food relations and production of juvenile chinook salmon in laboratory streams

Creator:: Seim, W. K. (Wayne K.)
Abstract:: This thesis reports the results of a study on the influence of biologically stabilized kraft mill effluent (SKME) on the food relations and production of juvenile chinook salmon, Oncorhynchus tschawytscha (Walbaum), in laboratory streams. Experiments were conducted at the Oak Creek Fisheries Research Laboratory, Oregon State University, during 1967 and...

An evaluation of attempts to reestablish the sea otter in Oregon

Creator:: Jameson, Ronald James
Abstract:: During the summers of 1970 and 1971 a total of 95 sea otter (Enhydra lutris) were shipped to Oregon from Amchitka Island, Alaska. The 1970 shipment consisted of 31 otter which were to be released on the southern Oregon Coast near the town of Port Orford. Two of these animals...

Interactions between grizzly bears and hikers in Glacier National Park, Montana

Creator:: Jope, Katherine Louise McArthur
Abstract:: Behavior of grizzly bears (Ursus arctos) toward people was studied by examining hikers' reports of grizzly bear observations and by intensively observing grizzlies in an area of Glacier National Park that was heavily used by day-hikers. Of concern were the apparent habituation of grizzly bears to people in the study...
