Fish and invertebrate distribution at multiple scales in Thomas Creek, Oregon : a transition from conifer uplands to agricultural lowlands

Creator:: Langshaw, Russell B.
Abstract:: Longitudinal patterns of fish and benthic invertebrate distribution and habitat use were similar in Thomas Creek, Oregon but clarity of these patterns differed. I studied fish and aquatic invertebrates simultaneously, at multiple scales, and used multivariate statistical techniques to compare responses to the same environmental conditions. Both types of organisms...

Effects of Elevated CO₂ on Speckled Sanddab (Citharichthys stigmaeus) Behavior

Creator:: Andrade, Jessica F.
Abstract:: The direct and indirect effects of ocean acidification (OA) are a growing concern, particularly in areas already experiencing elevated levels of oceanic CO₂. Studies with marine fishes suggest that elevated CO₂ levels may affect behavior by interfering with an important brain neurotransmitter. Studies examining the effects of OA fish behavior...

Movement Patterns of Rockfishes at the Redfish Rocks Marine Reserve, Oregon

Creator:: Calvanese, Thomas P.
Abstract:: The effects of Marine protected areas (MPAs) on adult fish populations depend on the degree of protection provided, which is partly a function of MPA size and the spatial extent of fish movements. The Redfish Rocks Marine Reserve (RRMR) and MPA, located on the south coast of Oregon near Port...

Epizootiology of leptospirosis in some wild mammals in western Oregon

Creator:: Stewart, Thomas Walter
Abstract:: Two hundred thirteen mammals were captured on two study areas between April 1976 and August 1977. Samples of urine and kidney tissue from 202 mammals were cultured on media suitable for leptospiral growth. Leptospiral organisms were not isolated from tissue cultures. Sera from 88 mammals were examined by the microscopic...

An Evaluation of Collaborative Salmon Fishery Management in Prince William Sound, Alaska

Creator:: Sheridan, Thomas M.
Abstract:: Collaborative decision-making is often promoted as a means to achieve socially acceptable and enduring solutions to natural resource management issues, and one that holds promise for resolving “wicked” problems. However, success rates for implementation of collaborative recommendations are unknown. This paper explores challenges to collaborative salmon fishery management in Prince...

The influence of some environmental factors on the distribution of fishes in Upper Klamath Lake

Creator:: Vincent, David Thomas
Abstract:: The fishes of Upper Klamath Lake appeared to distribute themselves in three general groups during the summers of 1964 and 1965: (1) the chubs--unrestricted as to distribution with slight seasonal variations; (2) rainbow trout and yellow perch -- restricted to certain water conditions that exist only along the northern marsh...

Productivity and nesting habitat of Great Basin Canada geese : Umatilla National Wildlife Refuge

Creator:: McCabe, Thomas R.
Abstract:: Great Basin Canada goose (Branta canadensis moffitti) productivity and nesting habitat utilization were studied on the Columbia River within the boundaries of the Umatilla National Wildlife Refuge during the springs of 1974 and 1975. Five islands, BL-1, BL-2, SD-1, SD-2, and Telegraph Island (TI), contained 88 percent of the nesting...

Relationship between plant and butterfly community composition on upland prairies of the Willamette Valley, Oregon

Creator:: York, Melissa M.
Abstract:: Small remnants of 'natural' habitats exist today throughout much of the world. Upland prairies in the Willamette Valley, Oregon have been nearly eliminated by conversion to agriculture and other uses. As a result, very few prairies remain and at least four butterfly species that require this habitat appear to be...

Development and application of a resource selection model for pygmy rabbits

Creator:: Meisel, Jennifer K.
Abstract:: Pygmy rabbits (Brachylagus idahoensis) in Oregon and Washington are a sagebrush (Artemisia tridentata spp.) obligate species of concern because of declining populations and extirpation from much of their range. Efforts are underway to establish a captive bred population of the Columbia Basin pygmy rabbit in Washington state for reintroduction into...

Growth, residence, and movement of juvenile Chinook salmon within restored and reference estuarine marsh channels in Salmon River, Oregon

Creator:: Hering, David K.
Abstract:: Tidal wetland channels provide rearing habitat for juvenile Chinook salmon as they emigrate from freshwater habitat and prepare to enter the ocean. Widespread diking and drainage of estuarine marshes for agricultural and urban development may have contributed to a decline in salmon abundance in the Pacific Northwest, prompting efforts to...
