Resource Selection and Space Use of Western Long-eared Myotis (Myotis evotis) in a Western Juniper (Juniperus occidentalis) Woodland of Central Oregon

Creator:: Anthony, Christopher R.
Abstract:: Identifying habitat and spatial requirements of wildlife species across multiple spatial scales is a challenging, yet crucial component of wildlife management. Habitat use of bats is particularly difficult to study, and managing habitat to conserve bats is especially challenging because bats are highly vagile organisms that exploit several different types...

Elevational differences in UV-B response by the long-toed salamander (Ambystoma macrodactylum)

Creator:: Thurman, Lindsey L.
Abstract:: Global amphibian declines have been attributed to numerous and often synergistic causes, such as invasive species, pathogens, and ultraviolet-B (UV-B) radiation. The effects of these stressors are context dependent and can vary with location, species, and populations. As sensitivity to UV-B has shown inconsistencies across amphibian taxa, it can be...

Influence of dissolved oxygen concentration and swimming velocity on food consumption and growth of juvenile Coho salmon

Creator:: Hutchins, Floyd E.
Abstract:: Laboratory studies were conducted on the food consumption, growth, and bioenergetics of juvenile coho salmon (Oncoynchus kisutch) held at various swimming velocities and dissolved oxygen concentrations at 15 C. Food consumption and growth of salmon fed to repletion on housefly larvae (Mus domesticus) were reduced by increasing activity at and...

Potential for dispersal of the non-native parasite Myxobolus cerebralis : qualitative risk assessments for the state of Alaska and the Willamette River Basin, Oregon

Creator:: Arsan, E. Leyla
Abstract:: First introduced to the USA in 1958, Myxobolus cerebralis, the parasite responsible for whirling disease in salmonids, has since spread across the country causing severe declines in wild trout populations in the intermountain west. Recent development of risk assessment models used to assess the likelihood and consequences of exotic parasite...

The Effects of Tank Structure and Egg Size on the Production of Wild Steelhead (Oncorhynchus mykiss) Surrogate Fish

Creator:: Self, Katharine E.
Abstract:: One of the biggest hurdles for a juvenile salmonid (Oncorhynchus mykiss) is migrating downstream from freshwater spawning grounds to the ocean. Juveniles from wild broodstock were reared from the South Santiam River for more than 1 year at the Oregon Hatchery Research Center (OHRC) in Alsea, OR. The fish were...

Beyond the Benthos: The effects of stream restoration on habitat complexity and aquatic and riparian macroinvertebrate assemblages

Creator:: Lotz, Kelsey L.
Abstract:: Aquatic and riparian systems in the western United States have been highly modified by anthropogenic impacts since Euro-American settlement. Ecological restoration is a practice that has been widely conducted around the world to mitigate the degradation of these systems. The majority of stream restoration efforts have focused on improving in-stream...

Long-term Fuel Succession in the Sagebrush-steppe

Creator:: Reis, Schyler Ainsworth
Abstract:: Historically fire has been the primary disturbance factor in the sagebrush-steppe. The settlement of the West by Euro-Americans, grazing by domestic livestock, and the concomitant spread of invasive species have altered the historical fire regime. Understanding the long-term vegetation structure and fuel succession of the various sagebrush-dominated communities of this...

Over-wintering diet, growth, and prey available to juvenile coho salmon (Oncorhynchus kisutch) in the West Fork Smith River, Oregon

Creator:: Olegario, Anthony
Abstract:: Over-winter growth of juvenile salmonids may be linked to ocean survival and thus species persistence. Diet, growth, and prey available to juvenile coho, Oncorhynchus kisutch, were examined from December 2004 to April 2005 in four tributaries of the West Fork Smith River (WFSR), Oregon. Juvenile coho growth rate and condition...

A review of the deep water Liparidae from the coast of Oregon and adjacent waters

Creator:: Stein, David L.
Abstract:: Descriptions and distributions are given of 28 species of Liparidae occurring or possibly occurring below 200 m between San Francisco and northern Vancouver Island, with keys for their identifications. Nine genera are included: Careproctus, Elassodiscus, Lipariscus, Nectoliparis, Rhinoliparis, Acantholiparis, Paraliparis, and two new genera are described, Odontoliparis and Osteodiscus. Eight...

Managing adult hatchery summer steelhead for a recreational fishery with reduced hatchery and wild interactions

Creator:: Schemmel, Eva M.
Abstract:: Hatcheries whose purpose is to provide for a recreational fishery must minimize impacts on wild fishes. Management to reduce hatchery and wild interactions is especially important on river systems that contain Endangered Species Act (ESA) listed species. I examined adult hatchery summer steelhead, Oncorhynchus mykiss, behavior, current management and a...
