Jumping in with Both Feet: Exploring Factors that Shape Juvenile Amphibian Movement

Creator:: Bredeweg, Evan M.
Abstract:: Investigation into how animals move within the landscape is important for both understanding of ecological processes and conservation management. Animal movement is important in shaping life history transitions, demographics, individual fitness, and species distributions. However, as landscapes become increasingly affected by human activities, movement becomes important as species navigate landscapes...

Ecology of mallard ducklings on Lower Klamath National Wildlife Refuge, California

Creator:: Mauser, David M.
Abstract:: The ecology of female mallards (Anas platyrhynchos) and their broods was studied during 1988-90 on Lower Klamath National Wildlife Refuge, California. Survival of 127 radio-marked ducklings from 64 broods was 0.18 to 10 days of life, and 0.37 and 0.34 to fledging for 1988, 1989, and 1990, respectively. For the...

Population and behavioral responses of small mammals to silviculture and downed wood treatments in the Oregon Coast Range

Creator:: Waldien, David L.
Abstract:: Forest managers are challenged to provide timber revenues and other resources for society while protecting and enhancing components of biodiversity that are often associated with older forests or older forest structure, such as dead wood. We examined small mammal response to timber harvest in stands 8-10 years following group-selection, two-story,...

Nutritional ecology of cervids in old-growth forests in Olympic National Park, Washington

Creator:: Leslie, David M.
Abstract:: Nutritional ecology of unhunted and sympatric populations of Roosevelt elk, Cervus elaphus roosevelti, and Columbian black-tailed deer, Odocoileus hemionus columbianus, was investigated in old-growth forests of the Hoh Valley in Olympic National Park, Washington, from September 1979 to November 1981. Seasonal diets of both cervids generally were comprised of common...

Humpback Whale (Megaptera novaeangliae) Calling Behavior In Southeast Alaska : A Study In Acoustic Ecology And Noise

Creator:: Fournet, Michelle E. H.
Abstract:: Humpback whales (Megaptera novaeangliae) are a widely distributed baleen whale species, well known for their diverse acoustic behavior. On high-latitude foraging grounds, humpback whales produce a suite of non-song vocalizations (“calls”) in concert with foraging and social behavior. In this dissertation I investigated the role of calls in the acoustic...

Foraging ecology of barred owls where they are outcompeting the threatened northern spotted owl

Creator:: Baumbusch, Ryan C.
Abstract:: Following European-American colonization of North America and associated landscape changes, barred owls (Strix varia) underwent a dramatic expansion of their historical range. The barred owl expanded across the previously tree-less Great Plains that had limited their distribution, and into the forests along the west coast. In these western forests they...

The Response of Caspian Terns to Managed Reductions in Nesting Habitat in the Columbia Plateau Region, Washington State, USA

Creator:: Schniedermeyer, Ethan
Abstract:: Declines in populations of anadromous salmonids (Oncorhynchus spp.) in the Columbia River drainage basin have resulted in extensive programs to annually release large numbers of hatchery-raised juvenile salmonids in an effort to support salmonid restoration. The Pacific Flyway population of Caspian terns (Hydroprogne caspia) has grown from around 3,500 nesting...

Susceptibility of juvenile salmonids to avian predation : Are Caspian terns and double-crested cormorants only taking the sick and injured?

Creator:: Hostetter, Nathan J.
Abstract:: The ability to non-destructively assess fish condition and subsequently track fish behavior and survival can be vital in understanding natural and anthropogenic stressors and sources of mortality, especially in populations of fish listed as threatened or endangered. I investigated the use of a quick, non-lethal, external examination technique to assess...

Butterfly and flower community composition among prairie-oak ecosystem habitats in the Willamette Valley, Oregon

Creator:: Powers, Breanna F.
Abstract:: Prairie-oak ecosystems in the Willamette Valley, Oregon have experienced habitat loss and degradation; most of these ecosystems are fragmented into smaller patches. Prairie-oak butterfly species, in the Willamette Valley, have decreased dramatically due to loss or degradation of habitat. More research is needed on sustaining the populations of butterflies in...
