Potential barriers to movements and habitat selection of pygmy rabbits (Brachylagus idahoensis) after experimental translocation

Creator:: Lawes, Timothy J. (Timothy James)
Abstract:: I assessed potential barriers to dispersal using homing tendency and investigated the movements and settlement site selection of pygmy rabbits (Brachylagus idahoensis) after short distance translocations in southeastern Oregon from June – December 2008. I captured, radio marked, and translocated 59 pygmy rabbits 1-2 km across landscapes with (1) continuous...

Use of range sites by pronghorns in south central Oregon

Creator:: Herrig, Daniel M.
Abstract:: Relative use by pronghorns (Antilocapra americana) of 16 range sites was studied during summer and fall of 1971 and 1972 on Hart Mountain National Antelope Refuge, an area of high desert rangeland in south central Oregon. A Relative Use Index was developed based upon 1533 observations of pronghorns located on...

California condors in the Pacific Northwest : integrating history, molecular ecology, and spatial modeling for reintroduction planning

Creator:: D'Elia, Jesse
Abstract:: Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...

Daily activity patterns, survival, and movements of red tree voles (Arborimus longicaudus) in western Oregon

Creator:: Swingle, James Kerr
Abstract:: We radiocollared a sample of 61 red tree voles in Douglas County, Oregon and monitored their movements to determine daily, seasonal, and sexual differences in behavior and home range attributes. We also collected information on nest attributes, survival, and dispersal of the radiocollared voles. Individual voles were monitored for periods...

Ecological Effects of Tide Gate Upgrade or Removal: A Literature Review and Knowledge Synthesis - Final report

Creator:: Giannico, Guillermo, Souder, Jon, Tomaro, Londi, and Behan, Jeff
Abstract:: This document reports on findings, conclusions and recommendations derived from scientific literature and knowledge regarding the effectiveness of tide gate removal or upgrade in improving conditions for Oregon’s native migratory fish species, particularly salmonids, and other plant and animal species that utilize estuarine ecosystems. The project was commissioned by the...

The effect of landscape topography and in-stream habitat on the distribution, growth, and survival of Lahontan cutthroat trout (Oncorhynchus clarki henshawi) in a high desert watershed

Creator:: Boxall, George D.
Abstract:: Lahontan cutthroat trout (LCT) (Oncorhynchus clarki henshawi) are currently limited in their distribution to a patchwork of small isolated populations, the result of habitat degradation and natural variation in landscape and in-stream conditions. The objectives of this study were to determine how landscape level topographic features influence LCT distribution patterns....

Impacts of Range Management Decisions on Native Pollinators: Innovative Grazing Practices and Riparian Restoration

Creator:: Mitchell, Scott R.
Abstract:: Animal pollination is critical to plant reproduction in agricultural and wildland ecosystems. Much of the production of seeds and fruits in natural areas, which underlie many food webs, depends on pollination services by insects. The taxon responsible for delivering the bulk of these services in most temperate systems is bees....

Rare, endangered, and recently extirpated mammals in Oregon

Creator:: Olterman, James Howard
Abstract:: This paper lists, and gives individual accounts of, those Oregon mammals that at some time have been referred to as being of a status other than common. Although rare and endangered wildlife species were listed on a national level in the United States, the large areas of land included in...

Resource Selection, and Demographic Rates of Female Greater Sage-Grouse Following Large-Scale Wildfire

Creator:: Foster, Lee
Abstract:: Understanding the effects of habitat disturbance on a species' habitat selection patterns, and demographic rates, is essential to projecting the trajectories of populations affected by disturbance, as well as for determining the appropriate conservation actions needed to maintain those populations. Greater sage-grouse (Centrocercus urophasianus) is a species of conservation concern...

Migratory behavior and passage of redband trout (Oncorhynchus mykiss) in the Donner und Blitzen River, Oregon

Creator:: Anderson, Matthew C.
Abstract:: Salmonids in arid high-elevation streams find themselves at the fringe of their tolerance range. Under the conditions they endure in such environments, long-distance migratory movements among widely dispersed habitats may be an important mechanism for some fish to persist, and even thrive. The Donner und Blitzen (Blitzen) River redband trout...
