Fig. 6 Biogeographic reconstruction showing possible routes of dispersal as a function of asynchronous Central Range orogeny and eustatic falls in sea level. a Initial colonisation of western New Guinea during the late Miocene after the onset of orogeny in western new Guinea ~ 12 Mya. Colonisation from northern Australian mesic forests is inferred to have occurred during periods of lowered sea level when a deltaic environment, formed by the accumulation of shedding siliclastics, developed on the Arafura shelf. b Pliocene diversification of New Guinean sericornithinines coincides with a phase or rapid mountain uplift and suggests passive transport of species to higher elevations. c Pleistocene connectivity across the Torres Strait in the magnirostra group coincident with periods of lower sea level during glacial maxima. Dispersal across the Arafura shelf is unlikely at this time due to the contraction of mesic
