Genome-wide patterns of divergence and gene flow across a butterfly radiation.

abstract：:The Haute Island mouflon (Ovis aries) population is isolated on one small (6.5 km2) island of the remote Kerguelen archipelago. Given a promiscuous mating system, a cyclic demography and a strong female-biased sex ratio after population crashes, we expected a low effective population size (Ne). We estimated Ne using d...

In parts of their range, however, pure hybrid populations can...
