Mechanisms of Thermal Adaptation and Evolutionary Potential of Conspecific Populations to Changing Environments

Heterogeneous and everÔÇÉchanging thermal environments drive the evolution of populations and species, especially when extreme conditions increase selection pressure for traits influencing fitness. However, projections of biological diversity under scenarios of climate change rarely consider...

Monitoring Salmonid Hatchery Stocks with Parentage Based Tagging technology in the Columbia River Basin

Parentage-based tagging (PBT) is a large-scale tagging technology for monitoring and evaluating salmonid hatchery stocks. Implementation of PBT involves annual sampling of hatchery broodstock to create a parental genotype baseline. Offspring produced by these parents can be non-lethally sampled...

Supportive Breeding Boosts Natural Population Abundance with Minimal Negative Impacts on Fitness of Wild Chinook Salmon in Johnson Creek

A supplementation program, using 100% natural-origin fish for broodstock, for summer Chinook was initiated in Johnson Creek in 1998 to prevent extirpation and enhance natural production of this population within the Snake River spring/summer Chinook salmon Evolutionary Significant Unit listed as...

A Cautionary Tale for in situ Fluorometric Measurement of Stream Chlorophyll a: Influences of Light and Periphyton Biomass

The use of in situ fluorometry to estimate stream benthic chlorophyll a (Chl a) has the potential to substantially reduce sampling costs and increase the feasibility of spatial and temporal replication. We evaluated the utility of a bbe moldaenke BenthoTorch fluorometer by...
