Using environmental DNA to detect the invasive New Zealand mud snail (Potamopyrgus antipodarum) in freshwater

Creator:: Ponce, Jake J.
Abstract:: Environmental DNA (eDNA) detection of aquatic invasive species is at the forefront of aquatic conservation efforts because of decreased costs, increased response times, and increase of sensitivity for intercepting invasions with low density populations. Developments in eDNA technologies have improved detection probabilities for rare, indicator, and invasive species over the...

An Investigation of Stage 0 Restoration in California and Oregon

Creator:: Schneider, Charles W.
Abstract:: Stream restoration efforts have increasingly started to focus on management actions that restore ecological function rather than focusing on species-specific habitat needs. Restoration practitioners in the Pacific Northwest have implemented numerous large-scale floodplain restoration projects to restore stream function at the valley scale. Some of these projects attempt to restore...

Variation in the timing of coho salmon (Oncorhynchus kisutch) migration and spawning relative to river discharge and temperature

Creator:: LovellFord, Rachel M.
Abstract:: Coho salmon (Oncorhynchus kisutch) migration and spawning are unique components of the salmon life cycle because they require synchrony of behavior with other individuals as well as with acceptable fluvial conditions. As with other organisms that exhibit group mating behavior, it is likely that environmental cues trigger coho salmon movement...

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...

Ecosystem services provided by Olympia oyster (Ostrea lurida) habitat and Pacific oyster (Crassostrea gigas) habitat; Dungeness crab (Metacarcinus magister) production in Willapa Bay, WA

Creator:: Ramsay, Jessica
Abstract:: Oyster reefs provide an array of ecosystem services. Specifically, they provide structurally complex habitat for fish and invertebrate species such as the commercially important Dungeness crab, Metacarcinus magister. This ecosystem service, once provided by the native oyster Ostrea lurida, is now provided by the commercially cultured oyster Crassostrea gigas 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...

Applying Object-Based Supervised Image Classification in Large-Scale Floodplain Monitoring

Creator:: Vito, Olivia
Abstract:: Large, alluvial rivers are naturally diverse, both in structural complexity and as drivers of landscape dynamics. Floodplains provide a mosaic of habitat types for aquatic, semi-aquatic, and terrestrial organisms and act as the framework for vital chemical processes to occur. In large part, this variety is due to the ability...

Riverscape genetics of Oncorhynchus tshawytscha (Chinook salmon) in Siletz River, OR

Creator:: Davis, Chanté D.
Abstract:: Traditional analysis in population genetics evaluates differences among groups of individuals and, in some cases, considers the effects of distance or potential barriers to gene flow. However, many forces may shape genetic variation of organisms in riverine systems. Similarly complex research linking habitat heterogeneity and configuration to genetic structure has...

Monitoring Restoration in South Sister Creek : The Effect of Stream Enhancement Structures on Water Temperature

Creator:: Harewood, Alessandra Greer
Abstract:: This pilot study of South Sister Creek (8 km length) examined stream-scale (i.e., longitudinal trends) and sub-reach scale (less than 100 m) water temperature. Hourly summer temperature time-series data were gathered at four to seven locations along South Sister Creek in 2006, 2012, and 2013 and were used to explore...

Spatial relationships for vegetation in restored and reference salt marshes in the Salmon River Estuary, Oregon

Creator:: Chellew, Megan
Abstract:: In this thesis, the spatial patterns of vegetation and soils of reference and restored tidal marshes were compared to determine the extent to which restored sites differ from the reference site after 40 years of restoration. Vegetation surveys of 1m x 1m plots were conducted along previously-established transects of salt...
