Genomic Insights Into Inbreeding and Adaptive Divergence of Trout Populations to Inform Genetic Rescue.

ABSTRACT: Genetic rescue, specifically translocation to facilitate gene flow among populations and reduce the effects of inbreeding, is an increasingly used approach in conservation. However, this approach comes with trade-offs, wherein gene flow may reduce fitness when populations have adaptive differentiation (i.e., outbreeding depression). A better understanding of the interaction between isolation, inbreeding, and adaptive divergence in key traits, such as life history traits, will help to inform genetic rescue efforts. Stream-dwelling salmonids, such as the westslope cutthroat trout (Oncorhynchus lewisi; WCT), are well-suited for examining these trade-offs because they are increasingly isolated by habitat degradation, exhibit substantial variation in life history traits among populations
