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...

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...

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...

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...

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...

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...

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...

Susceptibility of Juvenile Steelhead to Avian Predation: the Influence of Individual Fish Characteristics and River Conditions

Creator:: Hostetter, Nathan J., Evans, Allen F., Roby, Daniel D., and Collis, Ken
Abstract:: Identification of the factors that influence susceptibility to predation can aid in developing management strategies to recover fish populations of conservation concern. Predator-prey relationships can be influenced by numerous factors, including prey condition, prey size, and environmental conditions. We investigated these factors by using juvenile steelhead Oncorhynchus mykiss from the...
