All in a DNA's work : conservation genetics and monitoring of the New Zealand endemic Maui's and Hector's dolphins

Creator:: Hamner, Rebecca Marie
Abstract:: The critically endangered Maui's dolphin (Cephalorhynchus hectori maui) and the endangered Hector's dolphin (C. h. hectori) are endemic to the coastal waters of New Zealand, where their primary threat is fisheries-related mortality. The Maui's dolphin is among the most critically endangered cetaceans in the world, with its remnant population primarily...

Greater Sage-Grouse Demography, Habitat Selection, and Habitat Connectivity in Relation to Western Juniper and its Management

Creator:: Olsen, Andrew C.
Abstract:: The expansion of native, woody plants is a global phenomenon with characteristics and effects that are often indistinguishable from exotic invasions. These expansions have largely been driven by altered fire regimes and favorable climatic conditions. In the Great Basin of western North America, expansion of conifers such as western juniper...

Ecology of Columbian black-tailed deer fawns in western Oregon

Creator:: Pamplin, Nathan P.
Abstract:: Little is known about Columbian black-tailed deer (Odocoileus hemionus columbianus) because of their elusive nature and the logistical difficulty of studying them in densely forested and mountainous terrain. The Oregon Department of Fish and Wildlife has identified fawn survival as an important gap in the current knowledge of demography and...

Photo-identification of Melon-headed Whales (Peponocephala electra) in the Marquesas Islands : Creation of the First Photo-identification Catalog and Estimation of Group Size and Minimum Abundance in a Remote Archipelago

Creator:: McClung, John Ralph, II
Abstract:: For many species of oceanic dolphins, photo-identification and genetic data indicate that these island-associated populations are demographically isolated from pelagic populations and that island-associated populations exhibit very different patterns of movement and habitat use. Melon-headed whales (Peponocephala electra) are generally considered a pelagic dolphin, but have been documented around oceanic...

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...

An analysis of guild structure of avian communities, Columbia River, Oregon

Creator:: Noyes, Cecilia Lea Barham
Abstract:: Effects of habitat and season on guild structure of avian communities were examined for islands in the estuary zone of the Columbia River, Oregon. Bird species were classified into guilds according to their major food item, typical foraging substrate, and foraging behavior. Variation in community structure indices (number of guilds,...

Juvenile survival and birth-site selection of Rocky Mountain elk in northeastern Oregon

Creator:: Rearden, Spencer N.
Abstract:: With declining populations and low calf recruitment in northeastern Oregon, much interest has been generated to study the survival rates and causes of mortality of Rocky Mountain elk (Cervus elaphus nelsoni). I investigated the causes of elk calf mortality and the effects of predation risk on birth-site selection by cow...

Worldwide phylogeography and local population structure of the rough-toothed dolphin (Steno bredanensis)

Creator:: Albertson, G. Renee
Abstract:: Several dolphin species have global distributions. The extent of their radiation and limits to gene flow are presumably a product of oceanographic features both recent and historical, behavioral specializations and social organization. Rough-toothed dolphins (Steno bredanensis) are globally distributed in tropical and subtropical waters and are generally found in depths...

Body Condition and Hormone Assessment of Eastern North Pacific Gray Whales (Eschrichtius robustus) and Associations with Ambient Noise

Creator:: Lemos, Leila S.
Abstract:: Anthropogenic activities have posed many threats to the oceans and marine life. Understanding how individuals are affected and physiologically respond to these threats is crucial and allows for management and conservation applications. I evaluated the overall health condition of a subpopulation of gray whales (Eschrichtius robustus) along the Oregon coast,...

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...
