The Genomic Basis of Fitness and its Potential for Understanding Responses to a Changing Climate

Abstract Excerpt:
Predicting fluctuations in the abundance and distribution of salmon populations, particularly in a changing climate, requires a comprehensive understanding of how both genomic and environmental variation affects fitness. Recent improvements in DNA sequencing technology and the increased availability of genomic resources now permit such research. Specifically, genetic markers associated with phenotypic and environmental variation can now be identified, and their integration has significant potential to provide insights into how populations may respond under different environmental scenarios.
