Headwater stream macroinvertebrates of the H.J. Andrews Experimental Forest, Oregon

Creator:: Frady, Charles H.
Abstract:: Recent studies of headwater streams have demonstrated their importance to overall watershed biodiversity, nutrient cycling, and energy flux. However, little attention has been paid to long-term effects of forest harvest on macroinvertebrate communities in headwater streams. This study investigated headwater stream macroinvertebrate communities in the H.J. Andrews Experimental Forest, Oregon,...

Relative abundance and habitat associations of small mammals in two forest types in southern Oregon

Creator:: Johnston, Aaron N.
Abstract:: I studied small-mammal communities and their response to grazing in mixed-conifer forests and oak woodlands in the Cascade-Siskiyou National Monument in southern Oregon. My objectives were to (1) compare small-mammal communities among forest types and grazing intensities, (2) identify riparian affiliated species, and (3) describe microhabitat associations. Over two years,...

Steller sea lions (Eumetopias jubatus) of Oregon and Northern California: seasonal haulout abundance patterns, movements of marked juveniles, and effects of hot-iron branding on apparent survival of pups at Rogue Reef

Creator:: Scordino, Jonathan
Abstract:: The Steller Sea Lion Research Initiative was passed in 2001 to provide funding to help scientists determine causes and solutions for the population crash of Steller sea lions (Eumetopias jubatus). In response to need to understand population dynamics of Steller sea lions, NOAA Fisheries has spearheaded a large-scale, range-wide research...

Delivering oxytetracycline to first-feeding zebrafish Danio rerio (Hamilton) and goby Asterropteryx semipunctata (Rüppell) larvae using lipid spray beads

Creator:: Temple, Ephraim E.
Abstract:: Effective treatment of larval bacterial diseases is a difficult problem when culturing ornamental fish. Oral administration of antibiotics using existing microparticle types is not effective due to high leakage rates; furthermore, injection of larvae is not practical. Treatment is currently limited to use of antibiotic baths, . In this study,...

Influence of landscape-scale variables on the age and growth of coastal cutthroat trout Oncorhynchus clarkii clarkii in headwater streams

Creator:: Rehe, William G., Jr.
Abstract:: This thesis provides the first general description of the natural variation in age structure, growth rates, and survival in headwater populations of coastal cutthroat trout Oncorhynchus clarkii clarkii from western Oregon, and a subsequent synthesis of these life-history characteristics across the range of the subspecies. Age, growth, and survival were...

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...

Seasonal floodplain wetlands as fish habitat in Oregon and Washington

Creator:: Baker, Cynthia F.
Abstract:: To begin to understand freshwater seasonal floodplain fish communities in the context of human alteration of the physical system, species introductions and wetland restoration efforts, I studied fish assemblages in fifteen seasonal floodplain wetlands within four geographic regions (coastal, upper Columbia River estuary, Puget Sound and eastern Oregon/Washington) in the...

Identification of candidate genes for survival and their use in predicting field performance of Pacific oyster Crassostrea gigas families in coastal waters

Creator:: Lang, Robert Paul
Abstract:: Summer mortality of farmed Pacific oysters causes financial losses for shellfish growers, and selective breeding to improve survival of offspring is a promising way to reduce losses. This dissertation has two objectives to assist the development of tools for use in selective breeding programs. Objective 1: Identify candidate genes for...

Greater sage-grouse movements and habitat use during winter in central Oregon

Creator:: Bruce, Jennifer R.
Abstract:: Greater sage-grouse (Centrocercus urophasianus), a sagebrush obligate species, has contracted in extent by nearly half its original distribution. This is primarily due to habitat loss and degradation over the past 150 years. During winter, sage-grouse depend completely on sagebrush habitat for food and cover, yet sage-grouse winter ecology has been...
