Abstract	:	Human-mediated hybridization is a serious and growing threat to the conservation of biodiversity worldwide. Introgressive hybridization between introduced rainbow trout (Oncorhynchus mykiss, RBT) and westslope cutthroat trout (Oncorhynchus clarkii lewisi, WCT) is widespread across much of historical range of WCT and is considered one of the top threats to the persistence of remaining WCT populations. The ecological and evolutionary consequences of RBT hybridization and the role of environmental conditions in mediating those consequences is largely unknown but critical for making management decisions. I investigated three fitness-related traits across multiple populations to improve our understanding of the genetic basis of fitness differences due to RBT admixture. Specifically, I asked: how does RBT admixture affect growth, migratory life history, and survival; do environmental conditions mediate the effects of RBT admixture; and does RBT introgression at specific loci explain differences in these traits?
