Status and habitat use of Columbian white-tailed deer in Douglas County, Oregon

Creator:: Smith, Winston Paul
Abstract:: A study conducted May 1978-December 1980 determined that the present geographic range of Columbian white-tailed deer, Odocoileus virginianus leucurus, (CWTD) in Douglas County, Oregon encompassed 1199km2. The area was predominately a Quercus woodland community, typical of the Interior Valley Zone of western Oregon. The CWTD distribution was not contiguous throughout...

Catch shares, fisheries, and ecological stewardship: a comparative analysis of resource responses to a rights-based policy instrument

Creator:: Essington, Timothy E., Melnychuk, Michael C., Branch, Trevor A., Heppell, Selina S., Jensen, Olaf P., Link, Jason S., Martell, Steven J. D., Parma, Ana M., Pope, John G., and Smith, Anthony D. M.
Abstract:: Rights-based approaches are potentially promising tools to meet conservation objectives in natural resource management. Here, we evaluated how population status and fishery production respond to catch shares, a rights-based policy instrument in fisheries whereby participants are granted a right to harvest a fraction of the allowable catch. By analyzing time...

The influence of sex, migration distance, and latitude on expression of anadromy in Oncorhynchus mykiss

Creator:: Ohms, Haley
Abstract:: The evolution and maintenance of multiple phenotypes within populations is an interesting evolutionary and ecological question, and is becoming increasingly important for the restoration and conservation of partially migratory species. In particular, why individuals adopt a particular phenotype has been the focus of numerous research efforts. In the partially migratory...

Natural-Channel-Design Restorations that Changed Geomorphology Have Little Effect on Macroinvertebrate Communities in Headwater Streams

Creator:: Ernst, Anne G., Warren, Dana R., and Baldigo, Barry P.
Abstract:: Stream restorations that increase geomorphic stability can improve habitat quality, which should benefit selected species and local aquatic ecosystems. This assumption is often used to define primary restoration goals; yet, biological responses to restoration are rarely monitored or evaluated methodically. Macroinvertebrate communities were inventoried at 6 study reaches within 5...

Multiscale assessment of thermal patterns and the distribution of chinook salmon in the John Day River Basin, Oregon

Creator:: Torgersen, Christian E.
Abstract:: This study examined the distribution and behavior of adult spring chinook salmon (Oncorhynchus tshawytscha) related to patterns of stream temperature and physical habitat at channel unit, reach, and basin-wide spatial scales in both a wilderness stream and a disturbed stream in the John Day River basin in northeastern Oregon. Thermal...

How the animals found their places : pattern detection, experimentation, and epistemology in a high desert stream fish assemblage

Creator:: White, Seth Michael
Abstract:: I examined the relative roles of biotic and abiotic factors in structuring redband trout Oncorhynchus mykiss distributions in the South Fork John Day. I first examined the relationship between the biological traits of the fish assemblage and riparian-geomorphic features in context of prevailing theories of stream ecology stemming from the...

Extent of DNA homology in some distantly and intimately related fishes

Creator:: Gharrett, Anthony John
Abstract:: An attempt was made to differentiate between runs of steelhead by comparing the reassociations of their DNA. Conditions for the reassociation were studied using E. coli DNA, and observations were made spectrophotometrically. Of the five buffers examined, 1.0 molar sodium perchlorate plus one-hundredth molar tris-HCl, pH 7.1, at 60° or...

Effects of habitat manipulations on California quail in western Oregon

Creator:: Oates, Russell M.
Abstract:: The effects of disking, food plantings, and wheat plantings on a population of California quail (Lophortyx californicus) were studied from fall 1976 to spring 1978 on the E.E. Wilson Wildlife Area, Oregon. Twelve 16.2-ha study sites were established: 3 study sites for each treatment and 3 control sites. Disked areas,...

The effects of rotational grazing and prescribed burning on bobwhite populations in south Texas

Creator:: Wilson, Marcia H.
Abstract:: Short-term effects of 3 grazing systems and prescribed burning on bobwhite (Colinus virginianus) populations were investigated on the Welder Wildlife Refuge near Corpus Christi, Texas, during spring (April through June) and fall (September through October) of 1976 and 1977. Two rotational systems, high intensity-low frequency (HILF) and four-pasture, deferred-rotation (4PDR),...

Determination of marine migratory behavior and its relationship to selected physical traits for least cisco (Coregonus sardinella) of the western Arctic coastal plain, Alaska

Creator:: Seigle, John C.
Abstract:: With increased resource development on the western Arctic coastal plain of Alaska (especially within the oil extraction industry) it is important to understand the basic life history attributes of whitefish stocks in the region in order to ensure appropriate management. These fish are a crucial part of subsistence harvests for...
