Development and Evaluation of an Animal-borne Active Acoustic Tag to Conduct Minimally Invasive Behavioral Response Studies on Marine Mammals

Creator:: Fregosi, Selene
Abstract:: Development of new research tools is needed to better understand the potential effects of a noisier ocean on individual and populations of marine mammals. Current behavioral response studies utilize ship-mounted sound sources to induce short-term noise-related behavioral responses in tagged animals. Combining the tag with the sound source into an...

From weakness to wisdom : Jane Austen transforms the female of sensibility tradition

Creator:: Mosher-Knoshaug, Jessica M.
Abstract:: The eighteenth-century female of sensibility was characterized by delicate nerves that allowed her to feel her surroundings and enabled her to choose virtue over vice more consistently than males. While females were considered virtuous, their "innate" delicacy or weakness became their dominant trait and the true focus of male admiration....

An Observational Study of the Effects of Wildfire on Hermit and Varied Thrush Distribution in the Mt. Washington Wilderness Area

Creator:: Woodrich, Samuel T.
Abstract:: The hermit thrush (Catharus guttatus) and the varied thrush (Ixoreus naevius) are focal species for conservation of forested habitats in Oregon. Although habitat associations have been defined for both species, their response to changes in vegetation following wildfire has not been well studied. To help fill this information gap, I...

Effects of stress on the reproductive performance and physiology of rainbow trout (Oncorhynchus mykiss)

Creator:: Contreras Sánches, Wilfrido M.
Abstract:: The environment under which fish are maintained as broodstock before reproduction is often stressful; however, the impact of stress on broodstock and gamete quality is not well known. We investigated the effects of stress over the final stages (i.e. the 3 months preceding ovulation) of sexual maturation of female rainbow...

Atlantic Puffin (Fratercula arctica) Foraging Ecology During Marine Heatwave Conditions

Creator:: Kennerley, William L.
Abstract:: Marine heatwaves (“MHWs”) are discrete periods of anomalously warm ocean conditions that can lead to shifts in the distribution and abundance of marine organisms. Low-trophic level, pelagic forage species are frequently among those affected by MHWs, often resulting in considerable impacts upon their predators. In the North Atlantic Ocean, Atlantic...

Runoff and Sediment Transport from Harvested Hillslopes to Riparian Buffers of Rocky Mountain Headwater Catchment

Creator:: Puntenney-Desmond, Kira C.
Abstract:: Shallow subsurface flow and surface runoff are spatially and temporally variable in forested environments. The location and timing of this runoff depends on both site characteristics (e.g., vegetation, soil texture, geology, and topography) and on time-varying conditions (e.g., soil water content, precipitation type, duration, magnitude, and intensity). Forest management activities...

Abstract:: The freshwater polychaete Manayunkia speciosa was identified as an obligate host of the salmonid parasite Ceratomyxa shasta in 1997, prompting increased research on the small benthic invertebrate. Ceratomyxa shasta infection in fish can cause mortality, and presents a disease risk for both hatchery and wild salmon and trout. Ceratomyxa shasta...
