The evolutionary history of Afrocanarian blue tits inferred from genomewide SNPs.

abstract：:To explore how biogeography, parasite life history and host vagility influences evolutionary codivergences, we followed a comparative phylogeography approach using a host-specific nonpermanent mite, Laelaps giganteus, that occurs on four rodent species within the genus Rhabdomys. A mtDNA COI haplotype network derived ...
