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...

Spatiotemporal Associations of Abundance and Vital Rates of Co-occurring Small Mammals in a Late Successional Forest

Creator:: Weldy, Matthew J.
Abstract:: Informed conservation of small mammals, ecosystems, and predators requires a detailed understanding of how small mammals species and communities vary in both space and time, as well as the relative cyclicity and synchrony of this variation. This variation can be especially informative to land managers interested in manipulating the abundance...

Population and behavioral responses of small mammals to silviculture and downed wood treatments in the Oregon Coast Range

Creator:: Waldien, David L.
Abstract:: Forest managers are challenged to provide timber revenues and other resources for society while protecting and enhancing components of biodiversity that are often associated with older forests or older forest structure, such as dead wood. We examined small mammal response to timber harvest in stands 8-10 years following group-selection, two-story,...

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...

Daily activity patterns, survival, and movements of red tree voles (Arborimus longicaudus) in western Oregon

Creator:: Swingle, James Kerr
Abstract:: We radiocollared a sample of 61 red tree voles in Douglas County, Oregon and monitored their movements to determine daily, seasonal, and sexual differences in behavior and home range attributes. We also collected information on nest attributes, survival, and dispersal of the radiocollared voles. Individual voles were monitored for periods...

The role of small mammals as dispersers of mycorrhizal fungal spores within variously managed forests and clearcuts

Creator:: McIntire, Patrick W.
Abstract:: Small-mammal community composition, microhabitat selection, and dispersal of mycorrhizal fungal spores were studied in southwestern Oregon. Sampled habitats exhibited structural variation resulting from silvicultural practices. In 1981, the effect of clearcut treatment on these phenomena was evaluated. In 1982, the effect of forest structure was studied. Discriminant function analysis (DFA)...

Home range and habitat use of pileated woodpeckers, western Oregon

Creator:: Mellen, Teresa Kim
Abstract:: Home range and habitat use by pileated woodpeckers (Dryocopus pileatus) were studied in the Coast Ranges of western Oregon. Radio-telemetry was used to determine home ranges of 11 woodpeckers and habitat use of 14 woodpeckers after young had fledged during summers from 1982 to 1985. Home range size for individual...

Nutritional ecology of cervids in old-growth forests in Olympic National Park, Washington

Creator:: Leslie, David M.
Abstract:: Nutritional ecology of unhunted and sympatric populations of Roosevelt elk, Cervus elaphus roosevelti, and Columbian black-tailed deer, Odocoileus hemionus columbianus, was investigated in old-growth forests of the Hoh Valley in Olympic National Park, Washington, from September 1979 to November 1981. Seasonal diets of both cervids generally were comprised of common...

Habitat use and densities of cavity-nesting birds in the Oregon Coast Range

Creator:: Nelson, S. Kim
Abstract:: I studied abundance patterns and habitat use of eight cavitynesting bird species in the Coast Ranges of Western Oregon during the spring and summer of 1985 and 1986. Three age classes of unmanaged Douglas-fir (Pseudotsuga menziesii) stands were selected for study: young (40-80 yrs), mature (80-200 yrs), and old-growth (>200...
