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...

New insights on an old topic : understanding the effects of forest harvest on trout in the context of climate

Creator:: Penaluna, Brooke E.
Abstract:: Studies of the effects of forest harvest on streams and fish have a long history in the Pacific Northwest. Results of this work have prompted development of new forest harvest practices that are more protective of these resources, but the effectiveness of these new practices has not been fully evaluated....

Carp, Climate, and Water Quality: Applying Systems Modeling to Ecosystem Recovery in Malheur Lake

Creator:: Pearson, James B.
Abstract:: Shallow lakes exist in either a clear or turbid state, with the clear state characterized by an abundance of aquatic macrophytes, diverse aquatic biota, low water column nutrients and phytoplankton biomass, whereas the turbid state is characterized by the opposite. These two distinct states are maintained by reinforcing (positive) feedback...

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...

A Contingency-Based Evaluation for Beaver Restoration of Salmon Habitat in Oregon Coastal Streams

Creator:: Stevenson, John R.
Abstract:: Streams across the western United States are impaired from human alterations that have reduced freshwater habitat by simplifying channel complexity and disconnecting floodplains (Knox et al., 2022; Waples et al., 2008; Wohl, 2014). Climate change is likely to continue exacerbating these risks by warming summer surface stream temperatures (Crozier et...

The Influence of Scale in a Structured Decision Making Framework for Chinook Salmon Management

Creator:: McDonnell, Kevin N.
Abstract:: The goal of my dissertation was to explore how scale influences stream restoration prioritization strategies for an anadromous species and identify influential uncertainties that exist at different scales. My objectives were to (1) produce a comprehensive review of the Chinook salmon management challenges in California’s Central Valley and identify the...

Linking Moral Obligations, Assumption-based Research, and Structured Decision Making to Inform Bull Trout Recovery

Creator:: Brignon, William R.
Abstract:: More than 1500 species of plants and animals in the United States are listed as threatened or endangered under the Endangered Species Act (ESA). The U.S. Departments of Interior and Commerce are required, under Section 4(f)(1) of the ESA, to develop recovery plans for ESA-listed species under the respective agency...

Consistency of associate degree definitions and graduation requirements in the California community colleges : perceptions of community college curricular leaders

Creator:: Borg, Carolyn Sue
Abstract:: The purpose of this study was to produce data and information that inform California Community College decision-makers of: (a) extent of variance in California's associate degree definitions and graduation requirements, and (b) perceptions of curricular leaders regarding the variances. Associate degree definitions and graduation requirements were compiled and analyzed from...
