The Genetic Architecture of Juvenile Migration in Rainbow Trout (Oncorhynchus mykiss)
… resident in freshwater habitats throughout their life history; while others have the ability to embark on tremendous marine migrations. Those that migrate undergo a suite of behavioral, morphological, and physiological adaptations in a process called smoltification. And while much is known of the …

Measuring the production of migratory Westslope Cutthroat Trout in tributaries to Priest River, Idaho
<p>Iteroparous salmonids that exhibit a migratory life history are essential to functioning metapopulations. They are demographically important as migratory females produce more eggs than non-migratory individuals. Additionally, they provide genetic support through gene flow, resulting in more …

MANAGEMENT AND LIFE HISTORY CONSEQUENCES OF HYBRIDIZATION BETWEEN WESTSLOPE CUTTHROAT TROUT (ONCORHYNCHUS CLARKII LEWISI) AND RAINBOW TROUT (ONCORHYNCHUS MYKISS)
… with estimates of introgression; what are life history differences between WCT and hybrids; and what are tradeoffs in restoring migratory life history in populations threatened by hybridization?</p> <p>The riverscape context plays a substantial role in the distribution of hybrids, as …

Investigating the relationships between biotic and abiotic factors affecting migratory behavior in Westslope Cutthroat Trout within the Priest River System
<p>Numerous salmonid species demonstrate diverse life histories, encompassing both resident and migratory behaviors. Migratory life histories play a pivotal role in maintaining metapopulations for various reasons, facilitating genetic exchange between populations and yielding larger-sized females …

Fishery, population dynamics and stock assessment of geelbek (Atractoscion aequidens), a commercially important migrant fish species off the coast of South Africa
… and differences in the vulnerability of life history stages to varying fishing pressure along South Africa's coastline. These models were developed using statistical programming environment R. The models were parameterised and calibrated using length and catch data from the National …

GENETIC POPULATION STRUCTURE AND CONSERVATION OF BULL TROUT IN THE EAST FORK BITTERROOT RIVER DRAINAGE, MONTANA
… listed as threatened by the U.S. Fish and Wildlife Service. Understanding and conserving the genetic and life history diversity of bull trout populations across their range is critical as conservation, management, and recovery plans are developed. Numerous studies in different regions have …
