Population Differentiation in two Northeastern Pacific Marine Species

Creator:: Curran, Lorne Sullivan
Abstract:: Population genetic techniques are now preeminent in differentiating wild populations. Natural resource managers rely on them in their efforts to restore viable populations of fish and wildlife. Overfishing adversely impacted Yelloweye Rockfish (Sebastes ruberrimus) on the U.S. West Coast in the late 20th century. Management actions included shutting down the...

An Analysis of Beliefs About Environmental Governance and Connection to Environmental Services and Disservices

Creator:: Fleming, Whitney L.
Abstract:: The natural environment provides important services and benefits to peoples’ health and lives. Conversely, environmental disservices can have negative impacts on humans such as through pollution, chemical toxins, and climate change. The combination of environmental services and disservices encompass how human health and wellbeing, and the environment are connected. As...

Evaluating the Ecological Trade-Offs of Riparian Thinning for Stream Ecosystems in Second-Growth Redwood Forests of Northern California

Creator:: Roon, David A.
Abstract:: Riparian forests provide a myriad of ecosystem functions for adjacent streams and rivers, and due to these linkages, changes in riparian forest conditions can have direct implications for stream ecosystems. Resource managers in the coast redwood forests (Sequoia sempervirens) of northern California (USA) are actively thinning second-growth stands to accelerate...

How Behavior, Physiology, and Ontogeny of Klamath Redband Trout Shape the Functionality of Habitats in a Landscape of Temperature Extremes

Creator:: Hahlbeck, Nicholas J.
Abstract:: Climate change is a global phenomenon, but natural selection occurs within landscapes. A central tenet of landscape ecology is that mobile species depend on complementary habitats, which are insufficient in isolation, but combine to support animals through the full annual cycle. For coldwater fishes, it is widely assumed that maximum...

Beyond the Benthos: The effects of stream restoration on habitat complexity and aquatic and riparian macroinvertebrate assemblages

Creator:: Lotz, Kelsey L.
Abstract:: Aquatic and riparian systems in the western United States have been highly modified by anthropogenic impacts since Euro-American settlement. Ecological restoration is a practice that has been widely conducted around the world to mitigate the degradation of these systems. The majority of stream restoration efforts have focused on improving in-stream...

Spatial Ecology and Species Interactions among Predators and their Prey

Creator:: Ruprecht, Joel S.
Abstract:: Carnivores have disproportionate effects in ecological systems but understanding their exact influences on ecosystems is a matter of great complexity and debate. Predators directly impact prey by killing them, and indirectly by modifying their behavior in response to predation risk. Yet how species interact, both among members of a carnivore...

Value of Prior and Novel Information in Managing a Mixed-Stock Recreational Chinook Salmon Fishery

Creator:: Jensen, Alexander J.
Abstract:: Many economically important Pacific salmon fisheries along the west coast of North America are mixed-stock, recreational systems, in which managers strive to account for interactions between fish, anglers, and management policy while balancing fishery access against conservation of vulnerable stocks. Specific challenges facing fisheries managers include limited control over angling...

Characterizing Fine-Scale Neutral and Adaptive Genetic Diversity of Oncorhynchus mykiss in the Klamath Basin Before Dam Removal

Creator:: Piotrowski, Stanley J.
Abstract:: An inextricable link exists between dams and human development in the Pacific Northwest, but they can fragment rivers and reduce genetic connectivity for freshwater and anadromous fishes. Since the early-twentieth century, a series of hydropower and irrigation dams on the mainstem Klamath River, California, has fragmented migratory corridors and eliminated...

Using DNA metabarcoding to describe biodiversity and disease dynamics

Creator:: Massey, Aimee L.
Abstract:: Land-use change, particularly in the form of the conversion of primary forest to forest-matrix systems, alters species communities and species interactions. Describing these often complex and nuanced species responses is one of the great challenges in ecology. Another complementary challenge is finding and using the most efficient means for collecting...

Long Term Trends and Sources of Sound in United States Waters

Creator:: Haver, Samara M.
Abstract:: Passive acoustic monitoring is a valuable tool for observing the status of marine environments. Comparisons of underwater soundscapes over temporal and spatial scales can provide data to inform marine conservation efforts, including protection of threatened and endangered species. This dissertation utilizes passive acoustic data collected via a broadly spaced array...
