Population and behavioral responses of small mammals to silviculture and downed wood treatments in the Oregon Coast Range

Creator:: Waldien, David L.
Abstract:: Forest managers are challenged to provide timber revenues and other resources for society while protecting and enhancing components of biodiversity that are often associated with older forests or older forest structure, such as dead wood. We examined small mammal response to timber harvest in stands 8-10 years following group-selection, two-story,...

Factors influencing spawning site choice by female Garibaldi, Hypsypops rubicundus (Pisces: Pomacentridae)

Creator:: Sikkel, Paul C.
Abstract:: The garibaldi, Hypsypops rubicundus, is a sexually monochromatic pomacentrid found in rocky subtidal areas of Southern and Baja California. During the spawning season, males attempt to attract females to a nest of red algae located within individually defended territories. Females were observed to enter the nests of several males before...

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...

Comparisons of fish assemblages and habitat associations in littoral zones of reservoirs in the Willamette Basin, Oregon

Creator:: Bennett, Paul Michael
Abstract:: The littoral zones of seven reservoirs in the southern Willamette Valley of Oregon were sampled with a boat electroshocker during the summer months of 1995 and 1996. Shoreline substrates were inventoried before sampling sites were randomly selected. Sampling sites consisted of 9 of 12 possible habitat types including four substrate...

Multiscale relationships of wintering birds with riparian and wetland habitat in the Willamette Valley, Oregon

Creator:: Adamus, Paul R.
Abstract:: Relatively little is known about wintering bird communities in lowlands of the Pacific Northwest, yet, the condition of winter habitats potentially can pose a major constraint on bird populations. I initiated a study to determine: (1) Which avian species use lowland riparian and wetland habitats in the Willamette Valley during...

Maternal effects, the environment, and age structure: A mechanistic fine-scale approach to describe a complex set of factors contributing to larval growth and survival

Creator:: Arnold, Linsey M.
Abstract:: The relationship between population characteristics and population productivity is fundamental to sustainable fisheries management, but predicting productivity remains a challenging task. Proposed mechanisms driving the variability in productivity at a given population size have included environmental and demographic factors related to the age structure of the population, but the broad-scale...

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,...

Transferrin variation and population differentiation in black-tailed deer

Creator:: Chinn, Edwin Kan Kit
Abstract:: Transferrin of Columbian black-tailed deer (Odocoileus hemionus columbianus) displayed two types of polymorphism. One type involved differences in sialic acid content. The nature of the other polymorphism is not known. A hypothesis for three codominant alleles at a common locus was proposed and tested by using the Hardy-Weinberg Principle. The...

In vitro host range of aquatic birnaviruses and their relationship to virulence

Creator:: Ögut, Hamdi
Abstract:: Of 109 aquatic birnaviruses (AB) belonging to 9 serogroup A, all replicated and produced rapid and extensive cytopathology in CHSE-214 and RTG-2 cells, whereas only half produced significant levels of cytopathological effect (CPE) in two nonsalmonid cell lines tested (EPC and FHM). In many instances it was found that although...

Virulence characteristics of infectious pancreatic necrosis virus (IPNV) in brook trout, Salvelinus fontinalis, fry

Creator:: Maret, Joseph J.
Abstract:: Infectious pancreatic necrosis (IPN) is an acute, contagious disease of trout fry and fingerlings caused by viruses of the family birnaviridae. IPN disease usually results in mortality that is inversely proportional to the age of the fish. While many studies have been carried out to increase our understanding of IPN,...
