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...

Vegetation and Small Mammal Responses to Western Juniper (Juniperus occidentalis) Control in Eastern Oregon

Creator:: Morozumi, Corinne N.
Abstract:: Shrub-steppe ecosystems of western North America provide habitat for many wildlife species, are important components of public and private rangelands, and offer recreational opportunities for millions of people. They are some of the most vulnerable ecosystems in the United States and have been altered by human activities such as livestock...

Benthic macroinvertebrates sampled above and below Cougar Dam

Creator:: Murphy, Christina A, Johnson, Sherri L., Gerth, William, Pierce, Todd, and Taylor, Gregory
Abstract:: This dataset accompanies the manuscript Unintended consequences of selective water withdrawals from reservoirs alter downstream macroinvertebrate communities in Water Resources Research. Benthic macroinvertebrates were collected from samples taken annually during the first two weeks of August from 2002-2007 and again in 2017 at six sites in the South Fork McKenzie...

Ecology of kokanee salmon and rainbow trout in Crater Lake, a deep ultraoligotrophic caldera lake (Oregon)

Creator:: Buktenica, Mark W.
Abstract:: Crater Lake, originally barren of fish, was stocked on an irregular basis from 1888 through 1941 with several species of salmonids. Two species occur in the lake today--kokanee salmon (Oncorhynchus nerka) and rainbow trout (Salmo gairdneri). This study was initiated in the summer of 1986 to evaluate the ecology of...

Aspects of the early life history of juvenile salmonids in the Dungeness River Estuary

Creator:: Sather, Nichole K.
Abstract:: The decline of many Pacific salmon stocks has stimulated interest in the early life history and habitat requirements of juvenile salmon. Although estuarine habitat associations of juvenile salmon have been investigated in many coastal areas of the eastern Pacific Ocean, until recently, little was known about juvenile salmonid ecology within...

Small mammal and bird abundance in relation to post-fire habitat succession in mountain big sagebrush (Artemisia tridentata ssp. vaseyana) communities

Creator:: Holmes, Aaron L.
Abstract:: Fire is an important disturbance mechanism in big sagebrush (Artemisia tridentata) communities, yet little is known about wildlife population dynamics during post-fire habitat succession. I estimated the abundance of small mammals and birds in relation to fire history in mountain big sagebrush (A.t. spp. vaseyana) communities on the Sheldon National...

Seasonal shifts in redband trout use of pools and their microhabitats in three central Oregon streams

Creator:: Hirsch, Christine L.
Abstract:: Redband trout density was examined in three forested streams in central Oregon at two scales, pool channel unit and microhabitat. Two streams were in roadless areas and one was in a "highly managed" watershed. At the larger spatial scale, trout displayed a seasonal shift in habitat use from early to...

Golden Eagles in Denali National Park and Preserve : productivity and survival in relation to landscape characteristics of nesting territories

Creator:: McIntyre, Carol L.
Abstract:: Denali National Park and Preserve (Denali) contains one of the highest densities of nesting Golden Eagles (Aquila cluysaetos) in North America. Productivity of this migratory population varies both temporally and spatially. Regardless of prey abundance, more fledglings are consistently produced at some nesting territories than others. In many raptor studies,...

Influence of habitat characteristics on Greater sage-grouse reproductive success in the Montana Mountains, Nevada

Creator:: Rebholz, James L.
Abstract:: Greater sage-grouse (Centrocercus urophasianus) populations have declined across their geographic range during the last century. They were once widespread throughout the Intermountain West, but lower annual productivity, likely caused by degradation and loss of suitable habitat, has greatly reduced their distribution and population densities. Habitat used for reproduction has been...
