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...

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...

Changes in size and age at maturity of Columbia River upriver bright fall chinook salmon (Oncorhynchus tshawytscha) : implications for stock fitness, commercial value, and management

Creator:: Beaty, Roy E.
Abstract:: The average size and age of chinook salmon (Oncorhynchus tshawytscha) caught in commercial fisheries along the Pacific Coast of North America have decreased substantially in this century. These declines might be caused in part by changes in size and age at maturity within the stocks contributing to those fisheries. Upriver...

The effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies

Creator:: Miller, Scott W.
Abstract:: I used current water management practices in central and eastern Oregon and Washington as natural experiments to quantify the effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies. Reduced discharge had direct (e.g. decreased velocity and wetted habitat) and indirect (e.g. increased conductivity and temperature) effects...

Combining Disparate Data Sources with Ecosystem and Integrated Models: Case Studies for Improving Management of Protected Species

Creator:: Chasco, Brandon E.
Abstract:: Globally, the number of threatened species is increasing and conserving them is a high priority to the scientific community. Assessing the status of these protected species is challenging due to missing, contested, and or contradictory data streams. Integrated models (IMs) provide a statistical framework for combining disparate data sources to...

Evaluating the influence of land use, drought and reach isolation on the occurrence of freshwater mussel species in the lower Flint River Basin, Georgia (U.S.A.)

Creator:: Shea, Colin P., Peterson, James T., Conroy, Michael J., and Wisniewski, Jason M.
Abstract:: North American freshwater mussels have been subjected to multiple stressors in recent decades that have contributed to declines in the status and distribution of many species. However, considerable uncertainty exists regarding the relative influence of these factors on observed population declines. 2. We used an occupancy modelling approach to quantify...

Habitat use, spatial ecology, and stable isotope variability of the Pacific harbor seal (Phoca vitulina richardii) along the Oregon coast

Creator:: Steingass, Sheanna M.
Abstract:: Pacific harbor seals (Phoca vitulina richardii) are one of Oregon’s most common coastal predators, numbering between 10,000 and 12,000 individuals (Brown et al. 2005b). They consume more than 149 species or types of marine prey within the Pacific Northwest, which include a large variety of commercially important fisheries species. Despite...

Movements and Settlement Site Selection of Pygmy Rabbits After Experimental Translocation

Creator:: Lawes, Timothy J., Anthony, Robert G., Robinson, W. Douglas, Forbes, James T., and Lorton, Glenn A.
Abstract:: We investigated the movements and selection of settlement sites of translocated pygmy rabbits (Brachylagus idahoensis) in southeastern Oregon from June to December 2008. We captured, radio tagged, and translocated 59 pygmy rabbits across big sagebrush (Artemisia tridentata ssp.) habitat with 3 categories of landscape fragmentation. We used radio telemetry to...
