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...

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...

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...

Breeding site selection by coho salmon (Oncorhynchus kisutch) in relation to large wood additions and factors that drive reproductive success

Creator:: Clark, Steven
Abstract:: The fitness of female Pacific salmon (Oncorhynchus spp.) with respect to breeding behavior can be partitioned into at least four components: survival to reproduction, competition for breeding sites, success of egg incubation, and suitability of the local environment near breeding sites for early rearing of juveniles. Accordingly, breeding sites should...

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...

Survival and Height Growth of Eight Tree Species Planted in Riparian Restoration Project Areas throughout the Coos Bay, Oregon Watershed

Creator:: Law, Lucie R.
Abstract:: Riparian areas are targeted for restoration activities because of the important ecological functions these areas provide. Millions of dollars are spent on riparian restoration projects, yet little long-term monitoring data are collected to understand the growth and survival of the planted trees and shrubs after initial project establishment. With the...

Bioenergetic evaluation of diel vertical migration by bull trout

Creator:: Eckmann, Madeleine
Abstract:: I evaluated hypotheses related to growth as a driver of depth use and diel vertical migration by bull trout (Salvelinus confluentus) in a thermally stratified reservoir. I applied a bioenergetic model to evaluate growth of bull trout in relation to potential patterns of diel depth use by bull trout in...

Effects of an engineered log jam on flow structure and complexity

Creator:: L'Hommedieu, William J.
Abstract:: The installation of engineered log jams (ELJs) is a common river restoration practice, implemented to modify flow structure and increase hydraulic complexity for the benefit of streambank protection and fish habitat. However, few studies have directly assessed the effects of ELJs on flow structure and complexity. This study presents a...

From Hydrology to Biology: How Abiotic Factors Structure Invertebrate Communities in a Free-Flowing River Network

Creator:: Hockett, Justin
Abstract:: Chapter 2: Aquatic macroinvertebrate communities have been shown to exhibit strong differences between erosional (riffle and run) and depositional (pool) macrohabitats of streams. A subset of these communities are aquatic insect taxa that are an important food source for riparian consumers like birds, bats, lizards, and spiders. Understanding the role...

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...
