Abundance and habitat associations of Washington ground squirrels in north-central Oregon

Creator:: Greene, Eric
Abstract:: Much of the Columbia River Basin has been cultivated for agriculture, which has reduced and fragmented the native shrub-steppe habitats. As a result, the range of the Washington ground squirrel (Spermophilus washingtoni) has been significantly reduced, prompting the states of Washington and Oregon to review their status. Consequently, I investigated...

Roosevelt elk habitat use in the Oregon Coast Range

Creator:: Pope, Michael D. (Michael Dickens)
Abstract:: Few studies have evaluated non-migratory Roosevelt elk (Cervus elaphus roosevelti) interactions and habitat use on lands undergoing extensive timber removal. We captured and radio-tracked for 14 months representatives from 29 different bands of elk across a 37,000 ha area of Oregon's Coast Range. We identified 6 habitat variables within individual...

Activity of bats in thinned, unthinned, and old-growth forests in the Oregon Coast Range

Creator:: Humes, Marcia Lynn
Abstract:: Ten species of bats occur in the Oregon Coast Range and are hypothesized to be associated with late-successional forests. The development of characteristics of late-successional forests in young forest stands can be accelerated through silvicultural practices such as thinning I examined the effects of thinning on the use of forests...

Amphibian communities and physical characteristics of intermittent streams in old-growth and young forest stands in western Oregon

Creator:: Lee, Yu Man
Abstract:: Intermittent, headwater streams recently have been recognized as important components of forest ecosystems and have been provided increased protection by the Northwest Forest Plan. However, few studies have examined their distribution, dynamics, and ecological roles, such as habitat for wildlife. My goal was to provide additional information on the ecology...

Selection of day roosts by female long-legged myotis (Myotis volans) in forests of the central Oregon Cascades

Creator:: Ormsbee, Patricia
Abstract:: Measuring habitat selection by bats is complicated by their intricate life cycle. Scaling habitat measurements to reflect a hierarchal habitat selection process can help to define habitat associations of bats. I assessed day roost habitat of female long-legged myotis at four scales: the roost structure, micro-habitat surrounding the roost, the...

A morphometric analysis of geographic variation within Sorex monticolus

Creator:: Alexander, Lois F.
Abstract:: Shrews previously recognized as Sorex monticolus were classified into two species (one with 14 subspecies, the other monotypic) on the basis of a morphometric analysis of 3610 individuals from throughout their range. Sorex m. neomexicanus has been recognized previously as a subspecies of Sorex monticolus but is recognized herein as...

Behavioral ecology of marbled murrelets (Brachyramphus marmoratus) in forest and marine ecosystems of Oregon

Creator:: Jodice, Patrick G. R., 1961-
Abstract:: Marbled Murrelets (Brachyramphus marmoratus) are threatened seabirds that are prone to disturbance both at sea and at old-growth forest nesting areas. I examined murrelet behavior and activity patterns in forest and marine ecosystems of Oregon. Diving behavior was studied during the 1995 and 1996 breeding seasons and was compared to...

Evolutionary history and speciation of the genus Tragopan

Creator:: Islam, Kamal
Abstract:: A study of the phyletic relationships among five species of tragopans and an outgroup, the Blood Pheasant (Ithaginis cruentus), was conducted from 1987 to 1991. Biochemical, behavioral, and external morphologic characteristics were compared. A cladistic approach was used to compare the behavioral, biochemical, and external morphologic data collectively, as different...

The effect of broadcast burning on the quality of winter forage for elk, westen Oregon

Creator:: Friesen, Cheryl Ann
Abstract:: The Roosevelt elk (Cervus elephus roosevelti) is a National Forest management indicator species on the westside of the Cascade mountains, Western Oregon. A Habitat Effectiveness model is used by State and Federal agencies to evaluate elk habitat in the region. Concerns about the model's lack of differentiation between winter and...
