Comparing anuran performance and movement

Creator:: Bredeweg, Evan M.
Abstract:: Movement in an important component of an animal’s life cycle when it relies on both aquatic and terrestrial habitats. When multiple species overlap in the use of these habitats, they rely on other methods to reduce competition for shared resources. This dataset measured the jumping performance and movement behavior of...

Jumping in with Both Feet: Exploring Factors that Shape Juvenile Amphibian Movement

Creator:: Bredeweg, Evan M.
Abstract:: Investigation into how animals move within the landscape is important for both understanding of ecological processes and conservation management. Animal movement is important in shaping life history transitions, demographics, individual fitness, and species distributions. However, as landscapes become increasingly affected by human activities, movement becomes important as species navigate landscapes...

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...

Development and application of steelhead (Oncorhynchus mykiss) kelt identification techniques

Creator:: Evans, Allen F.
Abstract:: The migrations upstream of pre-spawned adult steelhead (Oncorhynchus mykiss) and downstream of post-spawned steelhead (referred to as "kelts") can geographically and temporally overlap in the Snake River, leading to management challenges for populations listed under the Endangered Species Act (ESA). This thesis describes the development and application of a method...

Improving Pacific oyster (Crassostrea gigas) production through selective breeding

Creator:: Evans, Sanford, 1968-
Abstract:: Shellfish growers have expressed interest in developing high-yielding oyster strains through selective breeding. This dissertation has three objectives to help determine the effects of genetic and environmental variation on production traits (body weight, survival, and yield) of Pacific oysters grown in the Pacific Northwest. Objective 1: Determine if relative family...

The Genetics of Larval Fitness in the Pacific Oyster: Responses to Acidified Seawater and Temporally Dynamic Selection Processes

Creator:: Durland, Evan R.
Abstract:: The Pacific Oyster (Crassostrea gigas) is one of the most economically and ecologically significant shellfish species worldwide. In the Pacific Northwest United States (PNW), the sustainability oyster stocks is increasingly threatened by ocean acidification (OA), which has had significant negative effects on the aquaculture industry in this region over the...

The ecology of wild turkey (Meleagris gallopavo) foraging in Pacific Northwest ecosystems

Creator:: Evans-Peters, Sara Tondee
Abstract:: Wild turkeys (Meleagris gallopavo) were first successfully introduced into Oregon and Washington in the 1960s; the population has grown in size and expanded in distribution to a point where it provides an important recreational hunting opportunity in both states that generates significant funds for habitat conservation and contributes financially to...

Assessing biological values of Wetland Reserve Program wetlands for wintering waterfowl

Creator:: Evans-Peters, Graham, R.
Abstract:: The Wetland Reserve Program (WRP) is one conservation tool that mitigates national wetland loss and a primary goal for the program includes optimizing wildlife habitat by restoring wetland functions and values. Few studies have evaluated the WRP, which limits our understanding of its impact on wildlife populations. I assessed the...

Larval development in the Pacific oyster and the impacts of ocean acidification : differential genetic effects in wild and domesticated stocks

Creator:: Durland, Evan, Pierre De Wit,, Meyer, Eli, and Langdon, Chris
Abstract:: The adaptive capacity of marine calcifiers to ocean acidification (OA) is a topic of great interest to evolutionary biologists and ecologists. Previous studies have provided evidence to suggest that larval resilience to high pCO2 seawater for these species is a trait with a genetic basis and variability in natural populations....

Gene expression correlated with delay in shell formation in larval Pacific oysters (Crassostrea gigas) exposed to experimental ocean acidification provides insights into shell formation mechanisms

Creator:: Ventura, Alexander, Durland, Evan, De Wit, Pierre, and Langdon, Chris J.
Abstract:: Background: Despite recent work to characterize gene expression changes associated with larval development in oysters, the mechanism by which the larval shell is first formed is still largely unknown. In Crassostrea gigas, this shell forms within the first 24 h post fertilization, and it has been demonstrated that changes in...
