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...

Microhabitat selection of brood-rearing sites by greater sage-grouse in Carbon County, Wyoming

Creator:: Schreiber, Leslie A.
Abstract:: Declines in Greater Sage-Grouse (Centrocercus urophasianus, hereafter sage-grouse) populations could be attributed to low chick survival, which may be influenced by the availability of food and cover at sites used by females rearing broods. Habitat attributes important to broods may vary regionally; thus, it is necessary to understand factors affecting...

Greater Sage-Grouse movements and habitat use during winter in central Oregon

Creator:: Bruce, Jennifer R., Robinson, W. Douglas, Petersen, Steven L., and Miller, Richard F.
Abstract:: Greater Sage-Grouse (Centrocercus urophasianus) depend on sagebrush habitat for food and cover during winter, yet few sage-grouse winter ecology studies have been conducted. During January and February 2007, we monitored 22 radio-collared sage-grouse (7 females and 15 males) in central Oregon to characterize winter habitat use and movement patterns. We...

Medusahead Invasion Along Unimproved Roads, Animal Trails, and Random Transects

Creator:: Davies, Kirk W., Nafus, Aleta M., and Madsen, Matthew D.
Abstract:: Medusahead (Taeniatherum caput-medusae [L.] Nevski), an exotic annual grass, is rapidly spreading and causing ecological damage across the western United States. Because this exotic plant occupies vast areas and because management resources are limited, it is critical that land managers prioritize where they direct treatment and monitoring efforts. Identifying where...

Size-structured spatial patterns as a measure of larval dispersal and emigration

Creator:: Markle, Douglas F.
Abstract:: Size-structured spatial patterns in larvae of 2 sucker and 3 minnow species are described from fixed-site sampling in Upper Klamath Lake, Oregon, and are used to demonstrate patterns of size-based losses downstream and retention in the lake. The smallest larvae of shortnose suckers (Chasmistes brevirostris), Lost River suckers (Deltistes luxatus),...

Large wildlife removal drives immune defence increases in rodents

Creator:: Young, Hillary S., Dirzo, Rodolfo, Helgen, Kristofer M., McCauley, Douglas J., Nunn, Charles L., Snyder, Paul, Veblen, Kari E., Zhao, Serena, and Ezenwa, Vanessa O.
Abstract:: 1. Anthropogenic disturbances involving land use change, climate disruption, pollution and invasive species have been shown to impact immune function of wild animals. These immune changes have direct impacts on the fitness of impacted animals and, also, potentially indirect effects on other species and on ecological processes, notably involving the...

Red abalone propagation in Oregon

Creator:: Neilsen, Jack and Oregon. Fish Commission. Shellfish Investigations
Abstract:: The objective of this project was, "To establish, in Oregon, a coastwide red abalone sport fishery and a limited commercial fishery as stocks dictate." Starting in 1967, abalone were planted at Whale Cove in Lincoln County, and were later planted at the Rogue River Reef in the Gold Beach area...
