A Comparative Analysis of Literature Search Results for Chinook Restoration Project Evaluation Between 2012 and 2022 Western Pacific Studies in California, Oregon, and Washington

Creator:: Clark, Erica Jennifer
Abstract:: Pacific salmon are an integral part of ecosystems, industry, culture, and food source. Rapid declines and extirpation in many populations and species have caught the interest of environmentalists, scientists, recreational anglers, commercial fishers, general public, and economists. Billions of dollars have been spent to restore, return, improve, sustain dwindling populations...

Effects of Stage 0 Stream Restoration on Aquatic Macroinvertebrate Production

Creator:: Jennings, Jeremy C.
Abstract:: Contemporary stream restoration efforts increasingly prioritize restoring natural stream processes to regain lost ecosystem functions. Stage 0 stream restoration resets disturbed, channelized streams to a theoretical pre-disturbance state (“stage zero”). It is assumed that this valley-scale restoration/disturbance will restore natural abiotic and biotic processes, leading to greater primary and secondary...

The Influence of Lithology on Stream Metabolism in Mountain Systems

Creator:: Cargill, Samantha K.
Abstract:: Physical disturbance in streams has important effects on the metabolic rates of gross primary production (GPP) and ecosystem respiration (ER). Underlying lithology can control sediment size, amount, and evolution in the stream, influencing substrate stability and its effect on benthic organisms. We assessed the patterns of disturbance and recovery of...

Stage-structured interactions and their consequences across levels of biological organization

Creator:: Segui, Leah Mupas
Abstract:: A central challenge for ecology is to understand the dynamic nature of species interactions. A classic approach to community ecology assumes that individuals within a species are functionally identical and that consumer-resource dynamics can be predicted solely by using species abundances. However, one species can consist of multiple functional groups,...

Assessment of the causal linkages between forests and fish: implications for management and monitoring.

Creator:: Martens, Kyle D.
Abstract:: Understanding the causal links between riparian forests, streams, and salmonids is important to help understand the likely effects of forest management practices. Previous studies have identified three major causal pathways (Instream Cover, Light, and Hydrology) through which riparian forests influence streams, and ultimately stream fishes. To evaluate the potential importance...

The Benefits of Time: Characterizing Intra-and Inter-Annual Variability in Oregon Wetland Ecosystems Using the Landsat Spectral-Temporal Domain

Creator:: Fickas, Kate C.
Abstract:: The use of Landsat data has historically been constrained to spectral and spatial information derived from a carefully selected image or set of images. However, free and open access to Landsat imagery combined with advances in data storage and computing are revolutionizing how the Landsat temporal domain is used to...

A Novel Approach to Process-based River Restoration in Oregon : Practitioners’ Perspectives, and Effects on In-stream Wood

Creator:: Bianco, Stephanie R.
Abstract:: The widespread fragmentation, channelization, and simplification of river ecosystems has had acute environmental impacts, including degradation of water quality and habitat and biodiversity loss (Vörösmarty et al., 2010). These concerns have incited an increased focus on reestablishing ecological and hydrogeomorphological functions and improving habitat that has been lost in riverine...

Predator Conservation and Trophic Ecology

Creator:: Wolf, Christopher
Abstract:: Many of Earth’s terrestrial large carnivore species are threatened with extinction. As a result, some of the ecological effects associated with these species may be lost. With the goal of furthering large carnivore conservation research, I conduct three global scale analyses involving these species. First, I explore prey depletion as...

Mason’s Run brook trout (Salvelinus fontinalis): history, management challenges, and recommendations

Creator:: Russell, Joseph D., III
Abstract:: Brook trout (Salvelinus fontinalis) populations currently exist in less than half of their historic range in the state of New Jersey. The remaining populations are confined to the northwestern part of the state in the Highlands, Appalachian Ridge and Valley, and Piedmont physiographic provinces, with the exception of Mason's Run,...

Sediment transport modeling and implications for benthic primary producers in Oak Creek, OR

Creator:: Katz, Scott B.
Abstract:: The spatial and temporal variability of sediment transport processes in Oak Creek, OR was investigated and used to explore two study questions: 1) How do sediment transport processes influence benthic algal communities?, and 2) Can fluvial-hydraulic models make accurate predictions of bed load transport rates? Our study was conducted in...
