Modeling Fine-scale Avian Distributions and Densities with Multi-scale Models: Predicting the Past and Present

Creator:: Hallman, Tyler A.
Abstract:: Models of a species’ distribution and models of a species’ spatially explicit density are valuable tools for conservation. They allow researchers to estimate changes in distributions, densities, and populations, based on changing environmental conditions. To trust such estimates, however, the quality of models is exceedingly important. Model performance can be...

Simulation of environmental, biological, and fisheries effects on yields of English sole (Parophyrus [i.e. Parophrys] vetulus) off Oregon and Washington

Creator:: Hayden, Thomas R.
Abstract:: English sole is a major contributor to Oregon and Washington groundfish resources. In accordance with the continued trend of increasing fishing effort, in 1975 Oregon State University Sea Grant funded an extensive groundfish research program: the Pleuronectid Project. The purpose was to provide information to assist resource management agencies. This...

Environmental fluctuation and cohort strength of Dover sole (Microstomus pacificus and English sole (Parophrys vetulus)

Creator:: Hayman, Robert August
Abstract:: Models were developed that described cohort strength of female Dover sole (Microstomus pacificus) and female English sole (Parophrys vetulus) in stocks off the Columbia River as functions of environmental variables. The environmental variables considered were those that could hypothetically influence spawning success or survival. They included a spawning power index,...

Long-term variation in growth of Dover sole (Microstomous pacificus) and English sole (Parophrys vetulus), and its possible relationship with upwelling

Creator:: Kreuz, Keith Francis
Abstract:: Variation in growth rate of Dover sole (Microstomous pacificus) off Astoria and Brookings, and English sole (Parophrys vetulus) growth off Astoria and Coos Bay, Oregon was studied using the distance between annuli on scales and interoperculum bones indicating growth rate for Dover sole and English sole respectively. The age at...

Genetic Connectivity of Dungeness Crab (Cancer magister) in the California Current System and Puget Sound

Creator:: Jackson, Tyler M.
Abstract:: Understanding connectivity among exploited populations is critical to their sustainable management and long-term viability. In the marine environment, estimates of connectivity often rely on the use of genetic markers, as dispersal primarily occurs during a planktonic larval phase which is difficult to track using direct methods. In this thesis, we...

Landscape-Level Approaches to Desert Bighorn Sheep (Ovis canadensis nelsoni) Conservation in a Changing Environment

Creator:: Creech, Tyler G.
Abstract:: Landscape characteristics can strongly influence demographic and genetic processes in wildlife populations. Climate change and human land use are causing many landscapes to change rapidly, and the effects on wildlife populations must be understood to properly manage these threats and design effective conservation strategies. In this dissertation, I explored the...

Interactions between stocked trout and larval salamanders (Ambystoma macrodactylum) in high-elevation lakes

Creator:: Tyler, Torrey J.
Abstract:: The long-toed salamander (Ambystoma macrodactylum) is the top vertebrate predator in fishless high-elevation lakes in North Cascades National Park Service Complex (NOCA), Washington. The purpose of this research was to determine the effects of physico-chemical factors and introduced trout on abundance and behavior of A. macrodactylum larvae. Although high-elevation lakes...

Born to run? Integrating individual behavior, physiology, and life histories in partially migratory steelhead and rainbow trout (Oncorhynchus mykiss)

Creator:: Sloat, Matthew R.
Abstract:: Steelhead and rainbow trout are common names for marine-migratory (anadromous) and freshwater-resident forms of Oncorhynchus mykiss, a partially migratory salmonid fish. Anadromous and resident forms are sympatric and can produce offspring with a life history different from their own (i.e., steelhead parents can produce rainbow trout offspring and vice versa)....
