Effects of o,p'-DDE on the immune system of juvenile chinook salmon (Oncorhynchus tshawytscha)

Creator:: Milston, Ruth Helen
Abstract:: Environmental factors such as chemical contamination can have immunomodulatory effects on the immune response of fish and may be contributing to the decline in salmonid populations by augmenting disease susceptibility. Xenobiotics can interfere with the immune system at several levels of complexity, and different immune cells and processes have variable...

Aquatic food web responses to patchy shading along forested headwater streams

Creator:: Heaston, Emily
Abstract:: In small forested streams, changes in age and structure of riparian vegetation covering the stream have been shown to directly influence the amount of light reaching the stream benthos. Light has the potential to impact in-stream resources that support secondary production through constraints on primary productivity. The influence of landscape...

Climbers' preferred management actions : addressing resource and crowding impacts in Yosemite Valley

Creator:: Burns, Molly T.
Abstract:: As more people become interested in rock climbing, the need to understand climbers and their preferences and how their activities impact the resource are more vital than ever. With increased use, and with little empirical data about the Yosemite climbing community, park managers cannot adequately develop a comprehensive climbing management...

Voluntary environmental programs at an alpine ski area: influence of recreationists' knowledge, motivations, attachment, value orientations, and specialization

Creator:: Little, Christopher M.
Abstract:: Voluntary environmental programs (VEPs) have been created to encourage companies to engage in behaviors that mitigate environmental impacts (e.g., recycling, emissions reduction). Many ski areas participate in the Sustainable Slopes Program, an initiative that promotes VEPs in the ski area industry. Past research has addressed the performance of VEPs in...

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...

Aboveground vegetation and viable seed bank of a dry mixed-conifer forest at a wildland-urban interface in Washington state

Creator:: Snider, Gabrielle
Abstract:: Dry coniferous forests in the western United States are experiencing severe wildfires, insect outbreaks, forest disease epidemics and a growing presence of invasive species. Policies strongly emphasize reducing hazardous fuels at the Wildland Urban Interface (WUI) where communities and forests intersect. However, these areas present restoration challenges as they tend...

Rangeland privatization and the Maasai experience : implications for livestock herding, open space, and wildlife conservation in southern Kenya

Creator:: Sundstrom, Shiloh
Abstract:: For centuries in what is now southern Kenya and northern Tanzania, nomadic, Maasai livestock herders have coexisted with vast populations of wildlife. Today, both wildlife and the Maasai herding lifestyle, a vital component of Maasai culture, are threatened by changes to the landscape and losses in mobility, including the policy...

Comparison of spatial distribution and resource use by Spanish and British breed cattle in northeastern Oregon prairie ecosystems

Creator:: Sheehy, Cody M.
Abstract:: We studied the distribution and habitat selection differences between Spanish breed (Corriente and Longhorn mix) and British breed cattle (Angus, Hereford). This study was located on the Zumwalt prairie during the spring and fall and along the Imnaha river for the winter. Each trial ran for two weeks and in...

Behavioral responses of Rocky Mountain Elk (Cervus elaphus) to recreational disturbance

Creator:: Naylor, Leslie M.
Abstract:: I measured responses of free-ranging Rocky Mountain elk (Cervus elaphus) to recreational disturbance at Starkey Experimental Forest and Range, Oregon from April to October, 2003 and 2004. Resting, feeding, and travel activities of 13 cow elk were recorded at 5-minute intervals using Actiwatch™ motion sensors. Elk were subjected to four...

Tradeoffs and Synergies among Wild Ungulates, Early Successional Plant Communities and Management Intensification in Forest Plantations of the Oregon Coast Range

Creator:: Stokely, Thomas D.
Abstract:: As the global demand for natural resources increases, more land will be intensively managed for the production of commodities such as timber, with potential consequences to biodiversity, ecological functioning and ecosystem services provided to society. Although there is strong consensus that intensive land management practices can negatively affect biodiversity, less...
