Abstract excerpt

Genomic mechanisms explaining why some hybrid zones remain stable while others collapse into hybrid swarms are poorly understood. In Montana's Kootenai River Basin, native interior redband trout (Oncorhynchus mykiss gairdneri; IRT) and westslope cutthroat trout (O. lewisi; WCT) are naturally sympatric and historically exhibited limited hybridization. However, the introduction of allopatric coastal rainbow trout...
