Retention of low-fitness genotypes over six decades of admixture between native and introduced tiger salamanders.

BMC evolutionary biology - 18 May 2010

Johnson Jarrett R, Fitzpatrick Benjamin M, Shaffer H Bradley

Abstract excerpt

BACKGROUND: Introductions of non-native tiger salamanders into the range of California tiger salamanders have provided a rare opportunity to study the early stages of secondary contact and hybridization. We produced first- and second-generation hybrid salamanders in the lab and measured viability among these early-generation hybrid crosses to determine the strength of the initial barrier to gene exchange. We also...
