Temporal Evolution of Submarine Volcanoes and Seamount Trails

Creator:: Schnur, Susan R.
Abstract:: The spatial distribution and geologic histories of submarine volcanoes provide insight into submarine eruptive behavior, deep earth processes and plate tectonics. This dissertation examines the evolution of individual submarine volcanic edifices as well as linear trails of seamounts at three spatial and temporal scales. In order to understand constructive and...

Phylogeography, evolution, and conservation in forest-associated Pacific Northwest salamanders

Creator:: Wagner, R. Steven
Abstract:: Phylogeographic studies of six Pacific Northwest forest-associated salamanders provide insight into historical and contemporary processes on population genetic structure. Among Larch Mountain Salamanders (Plethodon larselli), cytochrome b mitochondrial (mtDNA) sequences (381 bp) and random amplified polymorphic DNA (RAPDs; 34 loci) supported separate Management Units for northern and southern populations (12...

Shifting Rural Quantification Towards Study of Health Disparities: Applications in Statistical and Spatial Analysis of Rural Colorectal Cancer

Creator:: Buchalter, Robert Blake
Abstract:: Quantitative measurement of the urban-rural continuum for examination of U.S. rural health disparities is a relatively new research area, where only a handful of studies have investigated health disparities using quantitative rural measures and even fewer have attempted to integrate health variables within said measures. Most U.S. rural health disparity...

The effects of thinning on stand and tree growth in a young, high site Douglas-fir stand in western Oregon

Creator:: Marshall, David D.
Abstract:: The Levels-of-Growing-Stock Studies in Douglas-fir is a regional cooperative to investigate the effects of levels of growing stock on young stand growth. The Hoskins installation, in western Oregon, was established in a dense, high site natural stand at total age 20 years. The initial thinning resulted in an immediate 131...

Life-history and physiological trade-offs to reproduction of invasive and noninvasive Rubus

Creator:: McDowell, Susan C.
Abstract:: The goal of this dissertation was to improve our understanding of the physiology and life-history of invasive plants and of the mechanisms underlying life-history trade-offs. I compared invasive and noninvasive species of Rubus (blackberry) that grow together in the Pacific Northwest. Three hypotheses were investigated: (1) Invasive Rubus have higher...

Starvation-survi[v]al studies on a marine Vibrio sp. and other selected marine bacteria

Creator:: Amy, Penny Susan
Abstract:: The starvation-survival patterns of 16 freshly isolated open ocean bacteria and in a psychrophilic Vibrio sp., Ant-300, were determined. These isolates displayed three survival patterns as determined by viable cell count. These were (a) a rapid increase followed by a decrease to a constant value (pattern of Ant-300 and 7...

The relationship of estradiol to embryo-maternal interactions in the llama

Creator:: Powell, Susan A.
Abstract:: In the first experiment, estradiol production was measured in cultured embryos collected on Days 7, 9, 11, 13 and 15 post-mating. Estradiol was detected in Day 7 embryos and production increased approximately 50-fold (P<0.05) in medium recovered from Day 13 compared to Day 11 embryos and was greatest (P<0.05) from...

Population demography, resource use, and movement in cooperatively breeding Micronesian Kingfishers

Creator:: Kesler, Dylan C.
Abstract:: Island systems and species are susceptible to extinction because of their small population size and an ecological naiveté from an evolutionary past lacking strong competition and predation. For example, only one-fifth of the world’s bird species occur on islands, yet more than 90% of the avian extinctions witnessed during historic...

California condors in the Pacific Northwest : integrating history, molecular ecology, and spatial modeling for reintroduction planning

Creator:: D'Elia, Jesse
Abstract:: Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...

Rapid endangered species assessment : a novel approach to improve extinction risk assessments in poorly known species

Creator:: Bianchi, Carlos A.
Abstract:: The number of endangered species is rapidly increasing while paucity of adequate information and resources delays establishment of conservation actions. The IUCN’s listing system is insufficient to determine conservation priorities and many species lack information even to be evaluated (i.e., “data deficient”). Here I proposed and tested the Rapid Endangered...
