“…By contrast, the species of Dendrolagus are united as a monophyletic group in parsimony and bootstrap analyses. Emergence of D. inustus as an outlier to the remaining species is consistent with a phylogenetic study based on cytochrome b (Bowyer et al 2003), but not the recent work combining nuclear and mitochondrial DNA, which reconstructs D. inustus as the sister to the other New Guinea species (Eldridge et al 2018). Earlier morphology-based assessments (Flannery & Szalay 1982;Groves 1982;Flannery et al 1996) and a second cytochrome-b analysis (McGreevy et al 2012) grouped the two Australian species, D. bennettianus and D. lumholtzi, with D. inustus.…”

Tree-kangaroos of the genus Dendrolagus occupy forest habitats of New Guinea and extreme northeastern Australia, but their evolutionary history is poorly known. Descriptions in the 2000s of near-complete Pleistocene skeletons belonging to larger-bodied species in the now-extinct genus Bohra broadened our understanding of morphological variation in the group and have since helped us to identify unassigned fossils in museum collections, as well as to reassign species previously placed in other genera. Here we describe these fossils and analyse tree-kangaroo systematics via comparative osteology. Including B. planei sp. nov., B. bandharr comb. nov. and B. bila comb. nov., we recognise the existence of at least seven late Cenozoic species of Bohra, with a maximum of three in any one assemblage. All tree-kangaroos (Dendrolagina subtribe nov.) exhibit skeletal adaptations reflective of greater joint flexibility and manoeuvrability, particularly in the hindlimb, compared with other macropodids. The Pliocene species of Bohra retained the stepped calcaneocuboid articulation characteristic of ground-dwelling macropodids, but this became smoothed to allow greater hindfoot rotation in the later species of Bohra and in Dendrolagus. Tree-kangaroo diversification may have been tied to the expansion of forest habitats in the early Pliocene. Following the onset of late Pliocene aridity, some tree-kangaroo species took advantage of the consequent spread of more open habitats, becoming among the largest late Cenozoic tree-dwellers on the continent. Arboreal Old World primates and late Quaternary lemurs may be the closest ecological analogues to the species of Bohra.

Effects of historical forest contraction on the phylogeographic structure of Australo‐Papuan populations of the red‐legged pademelon (Macropodidae: Thylogale stigmatica)

Geographic patterns of genetic variation are strongly influenced by historical changes in species habitats.Whether such patterns are common to co-distributed taxa may depend on the extent to which species vary in ecology and vagility. We investigated whether broad-scale phylogeographic patterns common to a number of small-bodied vertebrate and invertebrate species in eastern Australian forests were reflected in the population genetic structure of an Australo-Papuan forest marsupial, the red-legged pademelon (Macropodidae: Thylogale stigmatica). Strong genetic structuring of mtDNA haplotypes indicated the persistence of T. stigmatica populations across eastern Australia and southern New Guinea in Pleistocene refugial areas consistent with those inferred from studies of smaller, poorly dispersing species. However, there was limited divergence of haplotypes across two known historical barriers in the northeastern Wet Tropics (Black Mountain Barrier) and coastal mideastern Queensland (Burdekin Gap) regions. Lack of divergence across these barriers may reflect post-glacial recolonization of forests from a large, central refugium in the Wet Tropics. Additionally, genetic structure is not consistent with the present delimitation of subspecies T. s. wilcoxi and T. s. stigmatica across the Burdekin Gap. Instead, the genetic division occurs further to the south in mideastern Queensland. Thus, while larger-bodied marsupials such as T. stigmatica did persist in Pleistocene refugia common to a number of other forest-restricted species, species-specific local extinction and recolonization events have resulted in cryptic patterns of genetic variation. Our study demonstrates the importance of understanding individualistic responses to historical climate change in order to adequately conserve genetic diversity and the evolutionary potential of species.

“…Significant structuring and high sequence divergence among populations and subspecies has been found for a number of New Guinean marsupials (e.g. Bowyer et al, 2003;Westerman et al, 2006;Malekian et al, 2010), reflecting the strong influence of topographic and ecological complexity on gene flow. Nevertheless, while this study and our previous phylogenetic analysis of the genus have highlighted significant variation among populations, specific and subspecific status of the endemic New Guinean Thylogale cannot be resolved without further, more comprehensive, sampling for morphological analyses and genetic analyses using nuclear DNA.…”

Aim Alternative hypotheses concerning genetic structuring of the widespread endemic New Guinean forest pademelons (Thylogale) based on current taxonomy and zoogeography (northern, southern and montane species groupings) and preliminary genetic findings (western and eastern regional groupings) are investigated using mitochondrial sequence data. We examine the relationship between the observed phylogeographical structure and known or inferred geological and historical environmental change during the late Tertiary and Quaternary.Location New Guinea and associated islands.Methods We used primarily museum specimen collections to sample representatives from Thylogale populations across New Guinea and three associated islands. Mitochondrial cytochrome b and control region sequence data were used to construct phylogenies and estimate the timing of population divergence.
