The subjective concept of health included in the self-rated health process allows identifying factors associated with good self-rated health in populations. This cross-sectional population-based study in 2007-2008 focused on self-rated health and associated factors among adults (n = 1,516) in Rio Branco, Acre State, Brazil. The multivariate analysis used Poisson regression, with fair/poor self-...

—Migratory and stock composition studies of Chinook salmon Oncorhynchus tshawytscha require genetic markers by which a large number of individuals can be processed in a relatively short time. Given the multijurisdictional geographic range of this species, it is further desirable that genetic markers and the corresponding data be transportable across laboratories. We developed 10 single nucleoti...

The SALMOD Chinook (Oncorhynchus tshawytscha) life cycle model for the Klamath River, California, USA was updated to address a number of computational and life history limitations based on over 10 years of accumulated experience. SALMOD II incorporates a complete spatial delineation of each mesohabitat unit between Iron Gate Dam and the Klamath estuary (~320 km). Mesohabitat specific relationsh...

The trophic habits, size and condition of yearling Chinook salmon (Oncorhynchus tshawytscha) caught early in their marine residence were examined during 19 survey years (1981-1985; 1998-2011). Juvenile salmon consumed distinct highly piscivorous diets in cold and warm ocean regimes with major differences between ocean regimes driven by changes in consumption of juvenile rockfishes, followed by ...

Body dimensions and swimming speeds of Atlantic salmon (Salmo salar) and chinook salmon (Oncorhynchus tshawytscha), ranging in weight from less than 1 to over 6 kg, were used to calculate the power needed to overcome drag. Fish were kept in 15 m×15 m×15 m deep cages, stocked under typical industrial conditions and fed to apparent satiation by broadcasting feed over the water surface. The averag...

Understanding how organisms interact with their environments is increasingly important for conservation efforts in many species, especially in light of highly anticipated climate changes. One method for understanding this relationship is to use genetic maps and QTL mapping to detect genomic regions linked to phenotypic traits of importance for adaptation. We used high-throughput genotyping by s...

The Hanford Reach of the Columbia River is a free flowing stretch that exists within the Hanford Nuclear Reservation in south central Washington, USA. Operations at the reservation have resulted in contamination of ground water with chromium and other chemical and radiological constituents. Ground water discharges into the Columbia River occur in areas where chinook salmon (Oncorhynchus tshawys...
