Host use evolution in Chrysochus milkweed beetles: evidence from behaviour, population genetics and phylogeny.

abstract：:Adaptation to new environments often occurs in the face of gene flow. Under these conditions, gene flow and recombination can impede adaptation by breaking down linkage disequilibrium between locally adapted alleles. Theory predicts that this decay can be halted or slowed if adaptive alleles are tightly linked in regi...
