Fig. 7From: Genomic differentiation tracks earth-historic isolation in an Indo-Australasian archipelagic pitta (Pittidae; Aves) complexRelationship between sea level fluctuations during the Late Pleistocene and the diversifications within three radiations of hooded pittas. The trees are extracted from the mitochondrial genome phylogeny (Additional file 2: Figure S3a) and dated by an assumed 2.1% per million year divergence between taxa. Purple bars indicate 95% credibility intervals. Interglacial periods with sea levels less than 50 m below present time are marked in blue (data from [18]). The populations in Sundaland (including Borneo, Java, Sumatra and peninsular Malaysia) and the Philippines seemingly underwent radiations during the last interglacial following the fragmentation of these regions caused by the raising sea levelBack to article page
