Concerted Pleistocene dispersal and genetic differentiation in passerine birds from the Tres Marías Archipelago, Mexico

摘要: ABSTRACT Studies in evolutionary biology have commonly been focused on insular systems because of their natural geographic isolation and relatively simpler biotas. Using mitochondrial DNA sequences 4 passerine bird species distributed the Tres Marias Archipelago (TMA) nearby mainland western Mexico—Cardinalis cardinalis, Turdus rufopalliatus, Vireo hypochryseus, Icterus pustulatus—we determined interspecific intraspecific phylogenetic relationships between populations, conducted age-based time calibration for estimation divergence times, used Bayesian analyses to examine colonization history islands. Specifically, we tested whether study from TMA share same since emergence islands ∼120 kya, taking advantage reduced due sea-level fluctuations during Pleistocene, or there were independent events. We also looked evidence genetic st...
