Foraging ecology, diving behavior, and migration patterns of harbor seals (Phoca vitulina richardii) from a glacial fjord in Alaska in relation to prey availability and oceanographic features

Creator:: Womble, Jamie N.
Abstract:: Understanding the movement behavior and foraging strategies of individuals across multiple spatial and temporal scales is essential not only for understanding the biological requirements of individuals but also for linking individual strategies to population level effects. Glacial fjords scattered throughout south-central and southeastern Alaska host some of the largest seasonal...

Structure, abundance, and distribution of pelagic zooplankton in a deep, oligotrophic Caldera Lake

Creator:: Karnaugh, Elena N.
Abstract:: From July 1985 to April 1987 the pelagic zooplankton community of Crater Lake, Oregon was studied to determine taxonomic structure, absolute and relative densities, and spatial and temporal distributional patterns. Samples were collected using vertically-towed zooplankton nets. The community structure consisted of two cladoceran and nine rotifer species, which were...

Temperature-modulated 7,12-dimethylbenz(a)antheracene carcinogenicity in rainbow trout

Creator:: Zahr, Camille Reda
Abstract:: Temperature influences the incidence of chemically induced cancer in fish, with warmer temperatures being associated with higher cancer incidence. The mechanisms of temperature-modulated chemical carcinogenesis in fish, however, have not been described in detail. Therefore, one primary objective of this study was increased understanding of how temperature-modulated genotoxicity of 7,12-...

Systematics and ecology of chubs (Gila : Cyprinidae) of the Alvord Basin, Oregon and Nevada

Creator:: Williams, Jack Edward
Abstract:: Seventeen populations of Gila Baird and Girard are identified from the Alvord Basin of southeastern Oregon and northwestern Nevada. Gila in the Alvord Basin occupy a wide range of habitats, including warm springs, cool springs, creeks, reservoirs, and a thermal lake. These populations became isolated in remnant habitats when waters...

The Ecophysiology of Thiamine Deficiency Complex : Evaluating Sources of Thiaminase in Great Lakes Food Webs

Creator:: Evans, Allison N.
Abstract:: Thiamine (vitamin B₁) is required by all living organisms for carbohydrate metabolism and synthesis of amino acids. Thiamine deficiency is responsible for several related classes of early life stage mortality disorders in salmonines, including Thiamine Deficiency Complex (TDC) in the Laurentian Great Lakes, Cayuga Syndrome in the Finger Lakes, and...

The Influence of Scale in a Structured Decision Making Framework for Chinook Salmon Management

Creator:: McDonnell, Kevin N.
Abstract:: The goal of my dissertation was to explore how scale influences stream restoration prioritization strategies for an anadromous species and identify influential uncertainties that exist at different scales. My objectives were to (1) produce a comprehensive review of the Chinook salmon management challenges in California’s Central Valley and identify the...

Direct and indirect effects of livestock grazing intensity on processes regulating grassland bird populations

Creator:: Johnson, Tracey N.
Abstract:: In grasslands, grazing by large ungulates can influence vegetation structure, composition, primary productivity, and ultimately, ecosystem functioning. While grazing represents a complex disturbance, grazing intensity largely determines the effects of grazing on vegetation. Structural and compositional changes in the plant community caused by grazing could have bottom-up effects on species...

Evaluation of Pacific Lamprey Entosphenus Tridentatus Anatomical Structures as Records of Age and Isotope Histories

Creator:: Pelekai, Keala N.
Abstract:: The anadromous Pacific Lamprey (Entosphenus tridentatus) is a biologically and culturally important species native to the North Pacific Ocean and its adjacent freshwater tributaries. Pacific Lamprey have experienced declines in abundance and distribution throughout their native range, highlighting a need for further research on the species to better inform conservation...

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,...
