Control and biology of feral goats on Aldabra Atoll, Republic of Seychelles

Creator:: Rainbolt, Raymond E.
Abstract:: The control of feral goats (Capra hircus) and relevant aspects of their biology were studied on Aldabra Atoll, Republic of Seychelles, from October 1993 - May 1994 and November 1994 - May 1995. A total of 832 goats were killed on Aldabra using both the Judas goat technique and traditional...

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...

Response of brood-rearing habitat of sage grouse to prescribed burning in Oregon

Creator:: Pyle, William H. (William Hanson), 1957-
Abstract:: Decline of western sage grouse (Centrocercus urophasianus phaios) in Oregon may be related to the reduced availability of foods in upland sagebrush (Artemisia)-grasslands used for brood-rearing. The goal of this study was to determine primary foods of chicks and the short-term response of brood-rearing habitat to prescribed burning at Hart...

Population Genetics of American Pika (Ochotona princeps) : Investigating Gene Flow and Genetic Diversity Across Multiple, Complex Landscapes

Creator:: Castillo, Jessica A.
Abstract:: American pikas (Ochotona princeps) are considered an indicator species of climate change. Adaptations for cold climates and active winters make pikas particularly sensitive to increasing temperatures. This, combined with evidence that multiple historically occupied populations have been extirpated within the past century, contributed to American pikas becoming a focal species...

Improving Projections of Tidal Marsh Persistence under Climate Change with Remote Sensing and Site-Specific Data

Creator:: Buffington, Kevin J.
Abstract:: Tidal marshes are dynamic ecosystems that are threatened by climate change and sea-level rise. To characterize baseline condition and historic climate sensitivities, and improve projections into the future, new methods are required that integrate data from the field and remote sensing platforms. Marsh elevation response models can be calibrated with...

Breeding bird community composition in relation to riparian vegetation structure in grazed habitats

Creator:: Sanders, Todd Alan
Abstract:: Riparian zones provide habitat for breeding birds in the semiarid western United States; however, there are few data available that address the effects of livestock grazing strategies on riparian habitats and avian communities. Documenting avian community composition in different riparian vegetation communities and relating vegetation communities to livestock grazing strategies...

Short-tailed weasel space use in managed forests of western Oregon

Creator:: Linnell, Mark A.
Abstract:: Although short-tailed weasels (Mustela erminea) are important predators of small mammals, little is known about their space use, habitat selection, or vulnerability to predation in North America. To evaluate the effects of forest management and social structure on home range size and habitat selection of short-tailed weasels, I conducted a...

Phylogeography and population structure of least terns (Sterna antillarum)

Creator:: Draheim, Hope M.
Abstract:: Historically, least terns (Sterna antillarum) were one of the most common tern species in North America. However, population declines have resulted from direct and indirect anthropogenic pressures on their breeding and foraging habitat. Three subspecies of least terns have been described within the United States: California least tern (S. a....

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...

Cultural and Environmental Creencias (Beliefs) and Latin@ Outdoor Recreation in the Willamette Valley of Oregon

Creator:: Justiniano, Isabel
Abstract:: In Oregon, outdoor recreation activities have continued to grow in popularity, as has the overall Latin@ population of the state. With the continual population increase of this ethnic group, researchers have focused on understanding their outdoor recreation habits through an environmental justice lens. This includes accessibility, affordability, and other barriers...
