Twenty-year changes in riparian bird communities of east-central Oregon

Creator:: Ellis, Michael S.
Abstract:: Over the last 50 years, riparian zones in the semi-arid West have gained recognition as disproportionately important habitats for both breeding bird communities and agricultural operations. Despite growing interest in exploring avian-habitat relationships in these systems to better inform land management, few studies have attempted to describe temporal changes in...

Transmission of the chewing louse, Damalinia (Cervicola) sp., from Columbian black-tailed deer (Odocoileus hemionus columbianus) to Rocky Mountain mule deer (Odocoileus hemionus hemionus) and its role in deer hair-loss syndrome.

Creator:: Robison, Jason A.
Abstract:: The potential for Rocky Mountain mule deer (Odocoileus hemionus hemionus) to host exotic chewing lice (Damalinia (Cervicola) sp.) believed to cause deer hair loss syndrome in Columbian black-tailed deer (Odocoileus hemionus columbianus), was investigated in captive deer held in pens at E.E. Wilson Wildlife Area, Corvallis, Oregon from March 2004...

The feasibility of a consumptive wild trout sport fishery on the North Fork of the Middle Fork of the Willamette River

Creator:: Nicholas, Jay W.
Abstract:: The objective of this study was to determine whether wild populations of trout in the North Fork of the Middle Fork of the Willamette River can support a catch rate of 0.3-0.5 trout per hour at current levels of effort and to predict how different size and bag limits would...

Temperature-modulated 7,12-dimethylbenz(a)antheracene carcinogenicity in rainbow trout

Creator:: Zahr, Camille Reda
Abstract:: Temperature influences the incidence of chemically induced cancer in fish, with warmer temperatures being associated with higher cancer incidence. The mechanisms of temperature-modulated chemical carcinogenesis in fish, however, have not been described in detail. Therefore, one primary objective of this study was increased understanding of how temperature-modulated genotoxicity of 7,12-...

Survival, movements and habitat selection of pygmy rabbits (Brachylagus idahoensis) on the Great Basin of southeastern Oregon and northwestern Nevada

Creator:: Crawford, Justin A.
Abstract:: I investigated survival, movements, home range sizes, and habitat selection of pygmy rabbits (Brachylagus idahoensis) in southeastern Oregon and northwestern Nevada from June 2005 to June 2007. I trapped 298 rabbits on four sites and fitted each with radio transmitters. More than 13,000 locations of telemetered rabbits were recorded. I...

Steller sea lions (Eumetopias jubatus) of Oregon and Northern California: seasonal haulout abundance patterns, movements of marked juveniles, and effects of hot-iron branding on apparent survival of pups at Rogue Reef

Creator:: Scordino, Jonathan
Abstract:: The Steller Sea Lion Research Initiative was passed in 2001 to provide funding to help scientists determine causes and solutions for the population crash of Steller sea lions (Eumetopias jubatus). In response to need to understand population dynamics of Steller sea lions, NOAA Fisheries has spearheaded a large-scale, range-wide research...

Status of prairie falcons breeding in Oregon

Creator:: Denton, Samuel Jonathon
Abstract:: Distribution of nest sites and reproductive success were determined for prairie falcons breeding in Oregon during 1973 and 1974. The study area encompassed a major portion of the eastern half of the state. I located and monitored 63 breeding attempts during the study and found nest sites in a variety...

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...
