Seasonal Movement of Coastal Cutthroat Trout (Oncorhynchus clarkii clarkii) in Headwater Streams in Oregon

Creator:: Linkem, Christina N.
Abstract:: Headwater streams in the Oregon Coastal Range are subject to drastic fluctuations in flow and temperature because of the changing seasonality of a Mediterranean climate. In response to these changes, stream fishes exhibit a variety of movement patterns. Coastal Cutthroat Trout (Oncorhynchus clarkii clarkii) have evolved an assortment of life...

Examining Wildlife Interactions with Large Wood In Streams

Creator:: Trevarrow, Ezmie R.
Abstract:: It is well known that in-stream large wood affects river channel shape, sediment deposits, stream flow, and available habitat for aquatic species. However, less is known about how wildlife interact with this large wood. Previous research has shown that small mammals and birds utilize woody debris in river channels for...

Mercury bioaccumulation in remote subalpine lakes : assessing the influence of invasive trout on salamanders

Creator:: Pfleeger, Adam
Abstract:: Mercury (Hg) contamination is a global conservation threat to freshwater ecosystems, detected in even the protected lakes of Olympic National Park (Washington, USA). Although considered some of the most remote and pristine US ecosystems, these lakes are currently subject to multiple environmental stressors, including climate change and fish introductions; adding...

Life-history strategies of rainbow trout (Oncorhynchus mykiss) across a volcanic disturbance gradient at Mount St. Helens, Washington

Creator:: Blackman, Tara Elizabeth
Abstract:: In this study, I examine the influence of habitat gradients created by the 1980 eruption of Mount St. Helens, Washington USA on a recently established Rainbow Trout (Oncorhynchus mykiss) population in the Spirit Lake basin. My goal was to evaluate the responses of fish in seven streams across a volcanic...

Post-breeding habitat selection by songbirds in the headwaters of the Trask River, northwestern Oregon

Creator:: Jenkins, Stephanie R.
Abstract:: Little is known on the importance of riparian areas to birds near small headwater streams in mesic forests. Progress towards understanding limiting factors that affect bird populations has been difficult because of lack of information beyond the breeding period. I compared bird assemblages between headwater riparian and upland areas throughout...

Effects of Aquatic Resource Subsidies on the Ecology of Terrestrial Top Predators

Creator:: Eriksson, Charlotte E.
Abstract:: Energetic resources transferred between distinct habitats or ecosystems, referred to as allochthonous resources, can greatly subsidize consumers in the recipient habitat, and thus influence food web structure and dynamics. Such subsidies may allow the growth of the consumer population to be decoupled from in situ productivity with effects on consumer...

Putting Food on the Map: Automated Mapping of Community Gardens with High Resolution Aerial Imagery using an Object Based Approach in Google Earth Engine

Creator:: Mazur, Elise S.
Abstract:: Urban agriculture (UA), or growing and producing food within urban areas, is rising in popularity across the United States. There are social and environmental benefits from growing food within urban neighborhoods. UA presents the opportunity for food security in neighborhoods that do not have access to safe and healthy foods,...

Spatial and Temporal Dynamics of Broad-scale Predictive Models : Influences of Scale

Creator:: Hooper, Samuel
Abstract:: Developing accurate predictive distribution models requires adequately representing relevant spatial and temporal scales, as these scales are ultimately reflective of the relationships between distributions and influential environmental conditions. In this research, we considered both spatial and temporal scale and the influence each has on predicting broad-scale distributions of two disparate...

The Impacts of Multiple Stressors on Aquatic Invertebrate Communities in the Umatilla River

Creator:: Clark, Hannah
Abstract:: Rivers impacted by human activities often have multiple stressors present. The effects of multiple stressors on biological communities can often be difficult to predict, due to the potential for complex interactions between stressors and communities. This thesis explores the impacts of two stressors often associated with agricultural land use, increased...

Tempo and Mode of Diversification in the Neotropical Fish Superfamily Anostomoidea (Ostariophysi: Characiformes)

Creator:: Frable, Benjamin W.
Abstract:: Neotropical characiform fishes form one of the most diverse freshwater ichthyofauna in the world. Knowledge of evolutionary processes that generated and maintain the immense characiform lineage and morphological diversity is still poorly understood. When did characiform lineages diversify? How have major geological and environmental changes affected diversification? Why are some...
