Small mammal responses to silvicultural fuels treatments in southwest Oregon

Creator:: Manning, Jeffrey A.
Abstract:: Despite the belief that fuels management, a form of prescribed fire that reduces accumulated fuels in commercially thinned forests, is necessary to restore forest 'health' in the Pacific Northwest, its effects on wildlife has received little attention in the scientific literature. Because fuels management is supported, funded, and implemented nationwide...

Home range and habitat use by Roosevelt elk in Olympic National Park, Washington

Creator:: Jenkins, Kurt Jeffrey
Abstract:: This research provides information on the distribution of an unexploited Roosevelt elk population in unaltered habitat in Olympic National Park. Radio-telemetry was used to document home range and habitat use by 11 adult cow elk in the Hoh Valley during March 1978, from 10 June-15 September 1978, and from 1...

Assessment of the quantitative fluorescent antibody technique and chemotherapy for the detection and control of Renibacterium salmoninarum in salmonid fishes

Creator:: Drongesen, Jeffrey Edward
Abstract:: Detection and treatment of bacterial kidney disease (BKD) was investigated. Experiments were conducted to evaluate the quantitative, fluorescent antibody technique (QFAT) that is used to detect, identify, and quantify both typical and 'bar form' Renibacterium salmoninarum cells. Smears of kidney tissue from naturally and artificially infected salmonids, both with and...

The winter distribution, movement, and smolt transformation of juvenile coho salmon in an Oregon coastal stream

Creator:: Rodgers, Jeffrey D.
Abstract:: The abundance of the 1982 brood of juvenile coho salmon (Oncorhynchus kisutch) was determined in August 1983, and January and April 1984 at 20 study sites spread throughout Knowles Creek, an Oregon coastal watershed. The timing of emigration of juvenile coho from the watershed was monitored from October 1983 through...

Columbia River salmonid outmigration : McNary Dam passage and enhanced smolt quality : completion report, April 1, 1985

Creator:: Schreck, Carl B. and Li, Hiram W.
Abstract:: We evaluated the effects of the McNary Dam transportation system on emigrating fall and spring chinook smolts using physiological indices of stress (e.g., plasma cortisol, hepatic glycogen, leucocrit, interrenal cell nuclear diameter) and performance tests (e.g., saltwater challenge, secondary stress challenge, disease resistance). We also conducted controlled experiments in a...

Conserving avian diversity in agricultural systems : the role of isolated Oregon white oak legacy trees

Creator:: DeMars, Craig A.
Abstract:: Over one third of the earth’s land surface has been modified to some extent for agricultural purposes. The large global footprint of agriculture, combined with the knowledge that existing reserve networks are likely insufficient for long-term conservation of native biodiversity, has necessitated that agricultural systems contribute to conservation of native...

Influences of environmental acidification on salmonid reproduction

Creator:: Weiner, Gary S.
Abstract:: Reproduction of salmonid fishes in acidic water was studied using the rainbow trout (Salmo gairdneri). Adult trout were exposed to various levels of hydrogen ion (pH levels 4.5, 5.0, 5.5, and control [6.5 to 7.1]) during the final 6 weeks of reproductive maturation. Reduced survival rates of the progeny of...

The role of body size in the foraging strategies and management of avian herbivores : a comparison of dusky Canada geese (Branta canadensis occidentalis) and cackling geese (B. hutchinsii minima) wintering in the Willamette Valley of Oregon

Creator:: Mini, Anne E.
Abstract:: Body size explains much of the interspecific variation in the physiology, behavior, and morphology of birds, such as metabolic rate, diet selection, intake rate, gut size, and bill size. Based on mass-specific metabolic requirements and relative energetic costs of activities, being a certain body size has both advantages and disadvantages....

Colonization and extinction in dynamic habitats: an occupancy approach for a Great Plains stream fish assemblage

Creator:: Falke, Jeffrey A., Bailey, Larissa L., Fausch, Kurt D., and Bestgen, Kevin R.
Abstract:: Despite the importance of habitat in determining species distribution and persistence, habitat dynamics are rarely modeled in studies of metapopulations. We used an integrated habitat-occupancy model to simultaneously quantify habitat change, site fidelity, and local colonization and extinction rates for larvae of a suite of Great Plains stream fishes in...

Eastern mosquitofish resists invasion by nonindigenous poeciliids through agonistic behaviors

Creator:: Thompson, Kevin A., Hill, Jeffrey E., and Nico, Leo G.
Abstract:: Florida is a hotspot for nonindigenous fishes with over 30 species established, although few of these are small-bodied species. One hypothesis for this pattern is that biotic resistance of native species is reducing the success of small-bodied, introduced fishes. The eastern mosquitofish Gambusia holbrooki is common in many freshwater habitats...
