Habitat segregation of two ambystomatids in mountain ponds, Mount Rainier National Park

Creator:: Brokes, Brendan J.
Abstract:: Ambystoma macrodactylum (long-toed salamander) and A. gracile (northwestern salamander) are two common salamander species occupying key trophic positions in mountain ponds of Mount Rainier National Park. The objective of this research was to document and evaluate the distributions and abundances of the two species, relative to habitat characteristics of ponds...

The effects of natural fire and recreational disturbance on montane forest ecosystem composition, structure and nitrogen dynamics, Crater Lake National Park, Oregon

Creator:: Wilson, John K. (John Kevin)
Abstract:: Disturbance, whether natural or of human origin, modifies to varying degrees many ecosystem attributes. Fire is a natural process in the montane forests of southern Oregon but for much of the 20th century fire was viewed as an apocalypse and thus fervently suppressed. Effective natural resource management requires an understanding...

Towards an Integrated Decision Tool for Managing Wildlife with Visitor Restrictions in Glacier Bay National Park

Creator:: Whitlock, Steven L.
Abstract:: The National Park Service has a dual mission of providing public access to exceptional natural resources, but in a manner such that these resources are left “unimpaired for the enjoyment of future generations.” Human activities in parks undoubtedly affect wildlife, but the degree to which such activities cause impairment is...

Interactions between grizzly bears and hikers in Glacier National Park, Montana

Creator:: Jope, Katherine Louise McArthur
Abstract:: Behavior of grizzly bears (Ursus arctos) toward people was studied by examining hikers' reports of grizzly bear observations and by intensively observing grizzlies in an area of Glacier National Park that was heavily used by day-hikers. Of concern were the apparent habituation of grizzly bears to people in the study...

Golden Eagles in Denali National Park and Preserve : productivity and survival in relation to landscape characteristics of nesting territories

Creator:: McIntyre, Carol L.
Abstract:: Denali National Park and Preserve (Denali) contains one of the highest densities of nesting Golden Eagles (Aquila cluysaetos) in North America. Productivity of this migratory population varies both temporally and spatially. Regardless of prey abundance, more fledglings are consistently produced at some nesting territories than others. In many raptor studies,...

Factors influencing spawning migration of bull trout (Salvelinus confluentus) in the North Fork Skokomish River, Olympic National Park, Washington

Creator:: Brenkman, Samuel J.
Abstract:: Distribution and life history characteristics of lacustrine-adfluvial bull trout (Salvelinus confluentus) were described in the North Fork Skokomish River Basin (including Lake Cushman, a reservoir) from 1994 to 1996. Day snorkeling was conducted in the river to determine initiation of the bull trout spawning migration, abundance of spawners, and duration...

Sea urchin-kelp forest communities in marine reserves and areas of exploitation : community interactions, populations, and metapopulation analyses

Creator:: Moctezuma, Gabriela Montaño
Abstract:: Marine ecosystems can be exposed to natural and anthropogenic disturbances that can lead to ecological failures. Marine reserves have been lately suggested to protect marine populations and communities that have been affected by habitat destruction and harvest. This research evaluates the potential role of two marine reserves established in Oregon...

Movement Patterns of Rockfishes at the Redfish Rocks Marine Reserve, Oregon

Creator:: Calvanese, Thomas P.
Abstract:: The effects of Marine protected areas (MPAs) on adult fish populations depend on the degree of protection provided, which is partly a function of MPA size and the spatial extent of fish movements. The Redfish Rocks Marine Reserve (RRMR) and MPA, located on the south coast of Oregon near Port...

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...

Life-history organization of cutthroat trout in Yellowstone Lake and its management implications

Creator:: Gresswell, Robert E.
Abstract:: Life-history organization of the cutthroat trout (Oncorhvnchus clarki) may be viewed at various levels, including species, subspecies, metapopulation, population, or individual. Each level varies in spatial scale and temporal persistence, and components at each level continually change with changes in environment. Cutthroat trout are widely distributed throughout the western USA,...
