Plant-herbivorous beetle networks: molecular characterization of trophic ecology within a threatened steppic environment.

abstract：:Isolation by adaptation increases divergence at neutral loci when natural selection against immigrants reduces the rate of gene flow between different habitats. This can occur early in the process of adaptive divergence and is a key feature of ecological speciation. Despite the ability of isolation by distance (IBD) a...
