Influences of Thermal and Trophic Heterogeneity on Phenology, Growth, and Resource Use by Juvenile Coho Salmon

Creator:: Campbell, Emily Y.
Abstract:: Ecological resources available to freshwater fish shift spatially, temporally and across life stages. To better understand how spatial-temporal availability of resources influence fish, I examined the phenologies of hatching and emergence of Coho Salmon (Oncorhynchus kisutch) in streams with contrasting and strongly defined seasonal thermal variability. The study streams included...

Distribution of juvenile salmonids and stream habitat relative to 15-year-old debris-flow deposits in the Oregon Coast Range

Creator:: Kirkby, Kristen-Marie S.
Abstract:: Debris flows, common disturbances in many mountainous areas, initially scour or bury stream habitats; however, debris flows deliver vast amounts of wood, boulders, and gravel that may ultimately form complex stream habitat to potentially support a diverse salmonid assemblage. The materials deposited by debris flows would otherwise be inaccessible to...

Headwater Dynamics: Quantifying Spatial Differences in Flow Permanence and Network Connectivity across Diverse Landscapes

Creator:: Pate, Adam A.
Abstract:: Forested headwater streams are critical for the supply of water, sediment, nutrients, and organic matter to downstream water bodies. Nearly half of all headwater streams display temporary flow regimes (i.e., non-perennial), but with climate change they may become more common. Thus, it will be increasingly imperative to adequately represent non-perennial...

Assessing the Thermal Sensitivity and Stormflow Response of Headwater Stream Temperatures: A Seasonal and Event-scale Exploration in Northern California, USA

Creator:: Wissler, Austin D.
Abstract:: Mountainous headwater streams make up ~80 % of stream length globally and are strongly connected with catchment hillslopes and riparian areas, which can influence water quantity, quality, and availability for downstream uses. Accordingly, effective management of headwater streams and riparian zones to maintain desired ecosystem services downstream is critical, particularly...

Population characteristics and movement patterns of redband trout (Oncorhynchus mykiss) and mountain whitefish (Prosopium williamsoni) in the Crooked River, Oregon

Creator:: Nesbit, Shivonne M.
Abstract:: Over the last decade, the Oregon Department of Fish and Wildlife (ODFW) has documented a precipitous decline in the Crooked River redband trout (Oncorhynchus mykiss) population, prompting this study to address potential factors contributing to the decline. There are two main goals to this project: (1) identify potential factors contributing...

A Bayesian network for prioritizing restoration of aquatic connectivity

Creator:: Andersen, Eric J.
Abstract:: Re-establishing connectivity is a primary restoration activity for enhancing the recovery of migratory fishes, but actions are often limited by lack of funds and understanding of the benefits of individual projects. The objective of this study was to develop a Bayesian Network (BN) to assess priorities for restoration of aquatic...

The influence of sex, migration distance, and latitude on expression of anadromy in Oncorhynchus mykiss

Creator:: Ohms, Haley
Abstract:: The evolution and maintenance of multiple phenotypes within populations is an interesting evolutionary and ecological question, and is becoming increasingly important for the restoration and conservation of partially migratory species. In particular, why individuals adopt a particular phenotype has been the focus of numerous research efforts. In the partially migratory...

Modeling Large Wood Impacts on Stream Hydrodynamics and Juvenile Salmon Habitat

Creator:: Bair, Russell
Abstract:: Large wood (LW) pieces are recognized as an important habitat component for salmon freshwater habitat. As such, they are often used in stream habitat restoration practices despite a lack of knowledge about their impacts on spatial and temporal hydraulic characteristics relevant to fish habitat. In this thesis we present results...

Pacific lamprey Entosphenus tridentatus : integrating traditional ecological knowledge and contemporary values into conservation planning, and stream substrate associations with larval abundance in the Willamette River Basin, Oregon, U.S.A.

Creator:: Sheoships, Gabe
Abstract:: Pacific lamprey Entosphenus tridentatus is a valuable icon and traditional food source for Indigenous people of western North America. Native Americans have utilized traditional ecological knowledge (TEK) since time immemorial to guide their ways of life, transmitting cultural values and natural history to further generational knowledge. Pacific lamprey are in...

Reconnecting aquatic habitats : validating historical habitat use by anadromous fishes using telemetry and stable isotope analysis above barriers

Creator:: Lewis, Sierra Koch
Abstract:: I conducted a study to identify potential spawning habitat for anadromous salmonids above a 60-year-old hydropower dam in the headwaters of the North Umpqua River in Oregon. Like many other historical salmonid-bearing rivers, little documentation exists for anadromous fish presence above potential natural obstacles upstream of Soda Springs Dam. My...
