Effects of wildfire on growth and demographics of coastal cutthroat trout in headwater streams

Creator:: Heck, Michael P.
Abstract:: Wildfire is a largely terrestrial perturbation broadly recognized as an agent of disturbance and ecological change in forested biomes. Effects of post-fire conditions on biotic components of aquatic systems have been less well-documented, although hypothetically, the two are strongly connected. In fact, the influence of wildfire may be most profound...

Using parasite community data and population genetics for assessing Pacific sardine (Sardinops sagax) population structure along the west coast of North America

Creator:: Baldwin, Rebecca E. B.
Abstract:: Pacific sardines (Sardinops sagax) are an economically and ecologically important forage fish which transfer energy from planktonic primary producers and secondary consumers to upper trophic predators. Previous genetics studies of Pacific sardine suggested a panmictic population with a shallow genetic structure. However, more than one subpopulation within the Central California...

Factors influencing within-watershed genetic variation of coastal cutthroat trout in Camp Creek, Oregon

Creator:: Wofford, John E.B.
Abstract:: Because human land use activities often result in increased fragmentation of headwater stream habitats, a better understanding of the effects of fragmentation on the genetic heterogeneity of stream salmonids is useful for effective management. We used eight microsatellites to examine the genetic structure of potamodromous coastal cutthroat trout (Oncorhynchus clarki...

Landscape-scale evaluation of genetic structure among barrier-isolated populations of coastal cutthroat trout, Oncorhynchus clarki clarki

Creator:: Guy, Troy J.
Abstract:: Although the effects of extrinsic barriers to dispersal have increasingly been shown to play a large role in the structuring of contemporary genetic diversity, describing the relationship between landscape structure, stochastic disturbance, and genetic diversity remains a major challenge. Here, environmental features for 27 barrier-isolated populations (2,232 individuals) of coastal...

Investigating Demographic and Evolutionary Factors Important for Fish Reintroduction

Creator:: Sard, Nicholas M.
Abstract:: Reintroduction programs are used to re-establish species back into their historical habitat. Most reintroduction programs have failed and few papers have evaluated factors that may be important to Pacific salmon. The 158 meter tall Cougar Dam has blocked Chinook salmon (Oncorhynchus tshawytscha) from accessing 40 kilometers of historical spawning and...

An investigation into the genetic basis of migration timing in Chinook salmon (Oncorhynchus tshawytscha)

Creator:: O'Malley, Kathleen G.
Abstract:: The genetic basis of adaptation is complex as many fitness-related traits are quantitative and likely influenced by multiple genes with variable effects across different selective environments. One important adaptation for anadromous Chinook salmon (Oncorhynchus tshawytscha) is the time at which individuals return to natal breeding sites within a reproductive season....

Spatial and temporal scales of genetic change in two overfished rockfishes

Creator:: Gomez-Uchida, Daniel
Abstract:: Pacific rockfishes (genus Sebastes) have attracted wide scientific and public interest from an evolutionary, fishery and conservation standpoints. This dissertation addresses several hypotheses involving spatial and temporal scales of genetic change in two overfished rockfishes, darkblotched (S. crameri) and canary rockfish (S. pinniger), using statistical analyses of genetic variation within...

Neural gene expression profiling in chinook salmon (Oncorhynchus tshawytscha) of alternate run times

Creator:: Bernier, Jeremiah C.
Abstract:: Chinook salmon (Oncorhynchus tshawytscha) display the greatest variability of return times to freshwater of all Pacific salmon. Differential return times to freshwater have segregated populations of Chinook into two broad types or runs, fall and spring, named for the time of year in which they migrate to freshwater. Migration time...

Thirty-four Kilometers and Fifteen Years : Rapid Adaptation at a Novel Chromosomal Inversion in Recently Introduced Deschutes River Three-spined Stickleback

Creator:: Hemstrom, William
Abstract:: Rapid adaptation and evolution based on standing genetic variation and novel mutations is likely to be one of the primary ways that species survive the widespread anthropogenic environmental changes expected of the next century. Three-spined stickleback (Gasterosteus aculeatus) are known to be capable of extremely quick, dramatic adaptation in response...

Population Differentiation in two Northeastern Pacific Marine Species

Creator:: Curran, Lorne Sullivan
Abstract:: Population genetic techniques are now preeminent in differentiating wild populations. Natural resource managers rely on them in their efforts to restore viable populations of fish and wildlife. Overfishing adversely impacted Yelloweye Rockfish (Sebastes ruberrimus) on the U.S. West Coast in the late 20th century. Management actions included shutting down the...
