Floodplain emergent wetlands as rearing habitat for fishes and the implications for wetland enhancement

Creator:: Henning, Julie A.
Abstract:: Seasonal emergent wetlands in the Pacific Northwest have not been regarded traditionally as fish rearing habitat, despite access to such habitat when river flows overtop riverbanks and connect to the floodplain. As a result, restoration and enhancement projects to remediate for the loss of such wetland habitat are being implemented...

Northern goshawk breeding habitat selection within high-elevation forests of southwestern Colorado

Creator:: Ferland, Cheron L.
Abstract:: The northern goshawk (Accipiter gentilis) is a species of concern in the western United States due to its association with mature structural stage forests. I employed a use-versus-availability study design to quantify the vegetative, physiographic, and landscape variables associated with goshawk breeding habitat selection in the San Juan Mountains of...

Evidence for Cross-Seasonal Effects: Insights from Long-term Data on Northern Pintail

Creator:: Zarzycki, Megan C.
Abstract:: Cross-seasonal effects, where conditions in one season can have consequences in a following season, can have population-level implications for migratory species. To assess the presence of cross-seasonal effects on a migratory dabbling duck population, we examined the relative importance of habitat conditions in multiple seasons on the subsequent productivity of...

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...

Piscivorous colonial waterbirds in the Columbia River estuary : demography, dietary contaminants, and management

Creator:: Suzuki, Yasuko
Abstract:: Caspian terns (Hydroprogne caspia) and double-crested cormorants (Phalacrocorax auritus) nest in large colonies on East Sand Island in the Columbia River estuary, the largest known colonies for the two species in the world. Both species of piscivorous colonial waterbirds have been identified as predators with a significant impact on the...

The ecology of wild turkey (Meleagris gallopavo) foraging in Pacific Northwest ecosystems

Creator:: Evans-Peters, Sara Tondee
Abstract:: Wild turkeys (Meleagris gallopavo) were first successfully introduced into Oregon and Washington in the 1960s; the population has grown in size and expanded in distribution to a point where it provides an important recreational hunting opportunity in both states that generates significant funds for habitat conservation and contributes financially to...

Movement Ecology and Population Dynamics of the Endangered Hawaiian Duck (Anas wyvilliana)

Creator:: Malachowski, Christopher P.
Abstract:: Fundamental objectives in the field of conservation biology involve understanding the processes that influence small and declining populations and applying that knowledge to develop appropriate monitoring strategies and targeted management and conservation actions. Critical first steps in determining the relative role of factors that drive population declines involves estimation of...

It’s in Their Bones: Ecological Drivers of Kemp’s Ridley Sea Turtle (Lepidochelys kempii) Somatic Growth and Population Dynamics

Creator:: Ramirez, Matthew D.
Abstract:: Somatic growth variation manifests from the cumulative effects of a suite of biological, ecological, and environmental processes and can have profound effects on individual fitness and species population dynamics. As ectotherms whose growth dynamics are greatly influenced by environmental factors, sea turtles display considerable variation in somatic growth within and...

Making the Connection: Linking Stress Physiology of Juvenile Northern Spotted Owls to Environmental Variation and Long-term Survival

Creator:: Mikkelsen, Ashlee J.
Abstract:: The northern spotted owl (Strix occidentalis caurina; spotted owl) is of conservation concern and endemic to mature forests of the Pacific Northwest. Adult survival has a strong effect on population growth rate, but juvenile survival and recruitment are also important components of population change. Despite the importance of this life...

Public lands and private waters: scarce mesic resources structure land tenure and sage-grouse distributions

Creator:: Donnelly, J. P., Naugle, D. E., Hagen, C. A., and Maestas, J. D.
Abstract:: Water scarcity in semiarid environments provides a model system to evaluate the role of mesic resources in structuring the distribution and abundance of wildlife. We used remote sensing and point process analyses to evaluate spatio–temporal variability in limited mesic resources in relation to greater sage-grouse (Centrocercus urophasianus) distributions in Oregon,...
