Habitat Selection by Greater Sage-Grouse During Winter in Southeastern Oregon

Creator:: Hagen, Christian A., Willis, Mitchell J., Glenn, Elizabeth M., and Anthony, Robert G.
Abstract:: The distribution and geographic range of Greater Sage-Grouse (Centrocercus urophasianus) have been reduced by 56% since European settlement. Although loss and fragmentation of sagebrush (Artemisia spp.) habitats have been cited as the primary causes for the decline of the species, degradation of existing habitat also has been considered an important...

Willamette Reservoir Food Web Data

Creator:: Murphy, Christina A., Romer, Jeremy D., Stertz, Kevin, Arismendi, Ivan, Emig, Ryan, Monzyk, Fred, and Johnson, Sherri
Abstract:: Isotope and stomach content data from piscivorous reservoir fishes collected from Hills Creek (isotopes; 43°40′16″N 122°25′33″W) and Lookout Point (isotopes and stomach contents; 43°53′48″N 122°43′34″W) reservoirs located on the Middle Fork Willamette River, Oregon. Additional details can be found in the related publication. Isotope sampling was conducted under OSU Institutional...

Tempo and Mode of Lineage and Morphological Diversification in a Hyperdiverse Freshwater Fish Radiation (Teleostei : Characiformes)

Creator:: Burns, Michael D.
Abstract:: Characiform fishes form one of the most diverse freshwater fish clades in the world. Comprising more than 2000 species and distributed primarily in South America and Africa, characiforms vary dramatically in their ecomorphology. However, the evolutionary processes responsible for the immense ecomorphological diversity remains unknown. Recently, a study postulated that...

Comparative wintering ecology of two subspecies of sandhill crane : informing conservation planning in the Sacramento-San Joaquin River Delta region of California

Creator:: Ivey, Gary L.
Abstract:: California's Central Valley agricultural landscapes provide several important wintering regions for Pacific Flyway sandhill crane (Grus canadensis) populations; however, the value of those regions is being compromised by urban expansion, other developments, and conversions to incompatible crop types. Greater (G. c. tabida) and lesser sandhill cranes (G. c. canadensis) both...

Factors influencing nest success of greater sandhill cranes at Malheur National Wildlife Refuge, Oregon

Creator:: Ivey, Gary L.
Abstract:: I developed a priori hypotheses and used logistic regression to model Greater Sandhill Crane (Grus canadensis tabida) nest success in relation to weather, habitat and management variables for cranes breeding at Malheur National Wildlife Refuge (MNWR) in southeast Oregon. My primary interest was to investigate the effects of habitat conditions...

An evaluation of the effectiveness of instream structures for steelhead trout rearing habitat in the Steamboat Creek basin.

Creator:: Fontaine, Barbara L.
Abstract:: Several types of instream structures were evaluated for their potential to provide rearing habitat and to increase reach carrying capacity for steelhead trout (Salmo gairdneri). Evaluation was conducted in each season over the course of 1 year. Blast pools created in bedrock glides increased the carrying capacity of stream reaches...

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...

Caspian tern (Hydroprogne caspia) foraging ecology and predation on juvenile salmonids in San Francisco Bay, California

Creator:: Adrean, Lindsay J.
Abstract:: Brooks Island, located in central San Francisco Bay, California, currently supports the largest breeding colony of Caspian terns (Hydroprogne caspia) in the Bay Area, and is one of several proposed relocation sites for some Caspian terns from the world's largest colony in the Columbia River estuary of Oregon. Juvenile salmonids...

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,...

Survival and behavior of juvenile steelhead trout (Oncorhynchus mykiss) in two small estuaries in Oregon

Creator:: Romer, Jeremy D.
Abstract:: A number of steelhead (Oncorhynchus mykiss) populations are at risk throughout Oregon, including five populations that are federally listed as threatened or endangered. However, little is known about behavior and survival of these fish as they transition from freshwater to seawater. We investigated whether estuarine survival varies on a temporal...
