Mark-recapture estimates of population parameters for selected species of small mammals

Creator:: Hammond, Ellen L.
Abstract:: I used program CAPTURE to analyze 1,535 data sets for 33 North American species of small mammals for sources of variation in capture probabilities and to characterize species-specific responses to markrecapture trapping. CAPTURE incorporates seven models to account for all possible combinations of heterogeneity (h), behavioral response (b), and time...

Assessing biological values of Wetland Reserve Program wetlands for wintering waterfowl

Creator:: Evans-Peters, Graham, R.
Abstract:: The Wetland Reserve Program (WRP) is one conservation tool that mitigates national wetland loss and a primary goal for the program includes optimizing wildlife habitat by restoring wetland functions and values. Few studies have evaluated the WRP, which limits our understanding of its impact on wildlife populations. I assessed the...

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...

Morphological changes in introduced eastern cottontails in Oregon

Creator:: Rhodes, Mark Nicolas
Abstract:: Descendants of eastern cottontails from Ohio (Sylvilagns floridanus) introduced in Benton County, Oregon and cottontails from Ohio were sampled and analyzed morphometrically and colorimetrically. In general, Oregon cottontails were smaller and lighter in color than Ohio rabbits. Introgression and interspecific competition with the smaller and darker colored native brush rabbit...

Selection of nesting and brood-rearing habitat by female ring-necked pheasants in the Willamette Valley, Oregon

Creator:: Meyers, S. Mark
Abstract:: During spring 1981, 112 radio-equipped female pheasants (Phasianus colchicus), were released in the Willamette Valley, Oregon. Hens were monitored to determine location of nest and brood-rearing sites. Vegetation around each nest and brood-rearing site was classified as one of 5 cover types available on the study areas. Further description of...

Impacts of forest-to-agriculture conversion on aboveground and soil carbon and nitrogen stocks along a bioclimatic gradient in Costa Rica

Creator:: Jobse, Judith C.
Abstract:: Tropical forest-to-agriculture conversions contribute to ~20% of contemporary global C emissions. Current global C flux estimates assume C is lost from vegetation and soils over time due to this conversion, and that C stocks in agricultural lands are fairly uniform across the tropics. Global C stock and flux estimates may...

Estimation of Population Age Structure, Detection Probability, and Density of Red Tree Voles in Oregon

Creator:: Marks-Fife, Chad A.
Abstract:: Red tree voles (Arborimus longicaudus) are a unique species of Arvicoline rodent found in western Oregon and northwest California. Their preferred habitat is mature and old-growth coniferous forest dominated by Douglas-fir (Pseudotsuga menziesii). Tree voles are an important prey item for northern spotted owls and many other predators, but are...

Phylogeography and population genetic structure of double-crested cormorants (Phalacrocorax auritus)

Creator:: Mercer, Dacey M.
Abstract:: The Double-crested Cormorant (Phalacrocorax auritus) is a widespread, colonial, North American waterbird with bicoastal and inland distributions. Four subspecies have been described within North America corresponding to five geographic breeding regions: Interior and North Atlantic cormorants (P. a. auritus); Southeastern cormorants (P. a. floridanus); Alaskan cormorants (P. a. cincinnatus); and...

Landscape level patterns in biodiversity : plant species and biomass structure

Creator:: Heider, Christopher
Abstract:: In the tropics, widespread deforestation and conversion of primary forests to agricultural and pasture lands has resulted in losses of composition, structure, and functions of forest landscapes. Deforestation in the tropics is typically preformed via slash-and-burn practices; the byproducts from combustion have been identified as the second-highest form of anthropogenically...

River-dependent bird species as potential indicators of ecosystem response to removal of dams on the Elwha River, Washington

Creator:: Blackie, Barbara
Abstract:: If two dams on the Elwha River are removed, the ecosystem will be open to the downstream flow of sediments and the upstream flow of marine nutrients in the form of anadromous fish. Nutrient enrichment may influence trophic dynamics of the entire ecosystem, extending beyond the aquatic boundary. I assessed...
