Hybridization at an ecotone: ecological and genetic barriers between three Iberian vipers.

abstract：:I derive the equilibrium values of sex-specific FST parameters, in an island model for a dioecious species with sex-biased dispersal and binomial distribution of family size before dispersal (as assumed in a Wright-Fisher population). I show that FST may take different values among males and among females whenever dis...
