Using Satellite Imagery to Count Nesting Albatross from Space

Creator:: Dolliver, Jane E.
Abstract:: One fundamental concern in conservation biology is species abundance. For many taxa, however, these data are costly to obtain via direct observation and thus limited in geographic or temporal scope. Very high-resolution satellite imagery provides a means to address these limitations and provide remotely-sensed counts of large, colonial species. We...

Disturbance and roosting ecology of California brown pelicans (Pelecanus occidentalis californicus) on East Sand Island in the Columbia River Estuary

Creator:: Wright, Sadie K.
Abstract:: The California brown pelican (Pelecanus occidentalis californicus) is listed as an endangered species under the U.S. Endangered Species Act. The Recovery Plan for this subspecies outlines the need to "Assure long-term protection of adequate food supplies and essential. . .roosting. . . habitat throughout the range." I investigated the effects...

Direct and indirect effects of livestock grazing intensity on processes regulating grassland bird populations

Creator:: Johnson, Tracey N.
Abstract:: In grasslands, grazing by large ungulates can influence vegetation structure, composition, primary productivity, and ultimately, ecosystem functioning. While grazing represents a complex disturbance, grazing intensity largely determines the effects of grazing on vegetation. Structural and compositional changes in the plant community caused by grazing could have bottom-up effects on species...

Foraging ecology of caspian terns and double-crested cormorants in the Columbia River Estuary

Creator:: Lyons, Donald E.
Abstract:: A detailed understanding of the foraging ecology of species preying upon threatened or endangered prey may contribute to identifying and evaluating management options to reduce predation, when such management is deemed appropriate. In the Columbia River estuary, Caspian terns (Sterna caspia) and double-crested cormorants (Phalacrocorax auritus) have been identified as...

Effects of body size on the survival and timing of emigration of newly metamorphosed Northern Red-legged frogs

Creator:: Chelgren, Nathan D.
Abstract:: The purpose of this study was to investigate the survival and movements of newly metamorphosed Northern Red-legged frogs (Rana aurora aurora) as they emigrated from two ephemeral breeding ponds. Quantifying survival and movement rates will be important to our understanding how changes to terrestrial and aquatic systems affect behavior and...

Planktivorous Auklets (Aethia pusilla and A. cristatella) nesting on St. Lawrence Island, Alaska as indicators of marine conditions in the northern Bering Sea

Creator:: Gall, Adrian
Abstract:: Monitoring reproductive success, prey species composition, and colony size of marine birds has been proposed as a method of assessing changes in marine systems that are otherwise difficult to sample (Cairns 1987). I measured inter-annual and intra-seasonal variability in reproductive parameters, taxonomic composition of the diet, and adult body condition...

Factors affecting colony size, reproductive success, and foraging patterns of double-crested cormorants nesting on East Sand Island in the Columbia River Estuary

Creator:: Anderson, Cynthia D.
Abstract:: The purpose of this study was to investigate the primary factors affecting colony size, reproductive success, and foraging patterns of Double-crested Cormorants (Phalacrocorax auritus albociliatus) nesting at East Sand Island in the Columbia River estuary, the largest colony of this species on the Pacific Coast of North America. This colony...
