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...

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...

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...

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...

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...

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...

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...
