Hydroclimatic and hydrochemical controls on Plecoptera diversity and distribution in northern freshwater ecosystems

Creator:: Kruitbos, Laura M., Tetzlaff, Doerthe, Soulsby, Chris, Buttle, Jim, Carey, Sean K., Laudon, Hjalmar, McDonnell, Jeffrey J., McGuire, Kevin, Seibert, Jan, Cunjak, Richard, and Shanley, Jamie
Abstract:: Freshwater ecosystems in the mid- to upper-latitudes of the northern hemisphere are particularly vulnerable to the impact of climate change as slight changes in air temperature can alter the form, timing, and magnitude of precipitation and consequent influence of snowmelt on streamflow dynamics. Here, we examine the effects of hydro-climate,...

Surface Water and Groundwater Interactions in the Walla Walla River, Northeast Oregon, USA : A Multi-Method Field-Based Approach

Creator:: Gryczkowski, Landon
Abstract:: Surface water and groundwater interactions are a key component in the functioning of stream ecosystems. Exchange of water between the stream and the hyporheic zone creates habitat for aquatic organisms and serves as a control for stream biogeochemical, thermal, and flow processes. This study takes a multi-method field-based approach to...

Anadromy and residency in steelhead and rainbow trout (Oncorhynchus mykiss): a review of the processes and patterns

Creator:: Kendall, Neala W., McMillan, John R., Sloat, Matthew R., Buehrens, Thomas W., Quinn, Thomas P., Pess, George R., Kuzishchin, Kirill V., McClure, Michelle M., and Zabela, Richard W.
Abstract:: Oncorhynchus mykiss form partially migratory populations with anadromous fish that undergo marine migrations and residents that complete their life cycle in fresh water. Many populations’ anadromous components are threatened or endangered, prompting interest in understanding ecological and evolutionary processes underlying anadromy and residency. In this paper, we synthesize information to...

The Relationship between Hydroregime and Coho Salmon (Oncorhynchus kisutch) Spawning in Three Streams of the Smith River Watershed, Oregon

Creator:: Baxter, Mackenzie R.
Abstract:: Migration and spawning phenology of Pacific Salmon is linked to the hydroregime, and thought to be triggered by increases in river discharge and decreases in water temperature. However, little data exists that describes direct fine-scale linkages between the hydroregime and spawning in Coho Salmon. This study evaluated the spatial and...

Over-wintering diet, growth, and prey available to juvenile coho salmon (Oncorhynchus kisutch) in the West Fork Smith River, Oregon

Creator:: Olegario, Anthony
Abstract:: Over-winter growth of juvenile salmonids may be linked to ocean survival and thus species persistence. Diet, growth, and prey available to juvenile coho, Oncorhynchus kisutch, were examined from December 2004 to April 2005 in four tributaries of the West Fork Smith River (WFSR), Oregon. Juvenile coho growth rate and condition...

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...

Use of Landscape Characteristics to Quantify Hybridization Risk Between Native and Introduced Salmonids

Creator:: Manning, Michael A.
Abstract:: The introduction of non-native species can negatively impact native species through reduced genetic fitness resulting from hybridization. The lack of spatiotemporal data of hybrids occurrences makes assessing hybridization risk difficult. Here, I developed a spatially-explicit GIS Hybridization Risk Model (HRM) between native ESA-listed Bull Trout and introduced Brook Trout by...

Beaver ecology on the west Copper River Delta, Alaska

Creator:: Cooper, Erin E.
Abstract:: Since the 1964 earthquake and geologic uplift, beavers (Castor canadensis) have expanded their historic range from the inland (outwash plain) Copper River Delta, Alaska to the once tidally influenced areas of the outer area (uplifted marsh). The uplift presents a unique opportunity to observe beaver expansion, habitat selection and influence...

Molecular Analysis of Environmental Water Samples as a Monitoring Method for the Fish Parasite Ichthyophthirius multifiliis

Creator:: Howell, Claire K.
Abstract:: Parasites are ubiquitous members of ecological communities, capable of contributing to the decline of vulnerable populations. Therefore, monitoring parasite level is a critical component for host management. Molecular tools, such as quantitative polymerase chain reaction (qPCR), can be valuable additions to monitoring protocols that assess parasitic disease risk to hosts....

Heterogeneous thermal habitat for northeast Oregon stream fishes

Creator:: Ebersole, Joseph L.
Abstract:: Discrete coldwater patches within warm streams provide potential thermal refuge for coldwater fishes during periods of heat stress. This analysis focused on heterogeneity in stream water temperatures as influenced by local influx of cooler subsurface waters. Using field thermal probes and recording thermistors, we identified and characterized coldwater patches potentially...
