“…Two mitochondrial gene segments and four nuclear regions were PCR-amplified (primers ; Table S2, Supporting information): mitochondrial control region (CR) and NADH dehydrogenase subunit 2 (ND2); noncoding nuclear x-globin (intron 2; omega-globin gene), protein coding portions of exon11 of the breast and ovarian cancer susceptibility gene (BRCA1). These markers have been widely utilized in marsupial phylogenetics (Fumagalli et al 1997;Osborne & Christidis 2001;Meredith et al 2008;Malekian et al 2010), and background information is also available on their molecular evolution in marsupials (e.g. x-globin; Wheeler et al 2001Wheeler et al , 2004.…”

Multiple biogeographical barriers identified across the monsoon tropics of northern Australia: phylogeographic analysis of the brachyotis group of rock‐wallabies

The monsoon tropics of northern Australia are a globally significant biodiversity hotspot, but its phylogeography is poorly known. A major challenge for this region is to understand the biogeographical processes that have shaped the distribution and diversity of taxa, without detailed knowledge of past climatic and environmental fluctuations. Although molecular data have great potential to address these questions, only a few species have been examined phylogeographically. Here, we use the widely distributed and abundant short-eared rock-wallaby (Petrogale brachyotis; n = 101), together with the sympatric monjon (P. burbidgei; n = 11) and nabarlek (P. concinna; n = 1), to assess historical evolutionary and biogeographical processes in northern Australia. We sequenced ∼1000 bp of mitochondrial DNA (control region, ND2) and ∼3000 bp of nDNA (BRCA1, ω-globin and two anonymous loci) to investigate phylogeographic structuring and delineate the time-scale of diversification within the region. Our results indicate multiple barriers between the Top End (Northern Territory) and Kimberley (Western Australia), which have caused divergence throughout the Plio-Pleistocene. Eight geographically discrete and genetically distinct lineages within the brachyotis group were identified, five of which are separated by major river valleys (Ord, Victoria, Daly), arid lowlands and discontinuous sandstone ranges. It is likely that these barriers have similarly influenced genetic structure in other monsoonal biota.

“…However, despite the importance of the Australo-Papuan region as an evolutionary centre and a biodiversity hotspot (Allison 2007), few studies have investigated population-level patterns of genetic diversity in terrestrial organisms of the area (Rawlings & Donnellan 2003;Murphy et al 2007;Kearns et al 2011;Macqueen et al 2011). Most genetic studies published from the region either contain little intraspecific sampling (phylogenetic studies; Keogh et al 1998;Osborne & Christidis 2001;Rawlings et al 2004;Wuster et al 2005;Norman et al 2007) and ⁄ or limited geographical sampling from within New Guinea (De Bruyn et al 2004;Baker et al 2008;Cook & Hughes 2010;Craft et al 2010). This may be due to the fact that many species in New Guinea have narrow ranges (Taylor et al 1982;Allison 2007), making the inference of broadscale patterns of intraspecific genetic structure in the Australo-Papuan region difficult.…”

Australia and New Guinea contain high levels of endemism and biodiversity, yet there have been few evaluations of population-level genetic diversity in fauna occurring throughout the Australo-Papuan region. Using extensive geographical sampling, we examined and compared the phylogenetic relationships, phylogeography and population structure of Anopheles farauti, An. hinesorum and An. irenicus throughout their ranges in the southwest Pacific using mitochondrial (mtDNA COI) and nuclear (ribosomal protein S9 and ribosomal DNA ITS2) loci. Phylogenetic analyses suggest that the ability to utilize humans as hosts has been lost repeatedly, coincident with independent colonizations of the Solomon Islands. As some of the species under investigation transmit malaria in the region, this is a medically important finding. Maximum likelihood and Bayesian phylogenetic analyses of nuclear loci also showed that the three species are monophyletic. However, putative introgression of An. hinesorum mtDNA onto a nuclear background of An. farauti was evident in populations from Queensland, Torres Strait and southern New Guinea. Haplotype networks and pairwise FST values show that there is significant genetic structure within New Guinea and Australia in both An. farauti and An. hinesorum, consistent with a long-term history of low gene flow among populations.

“…We here describe the development of a panel of microsatellite markers, carried out as part of a programme investigating the ecology of D. trivirgata . We also provide data on the utility of these microsatellites to provide polymorphic markers in several other petaurids, including Victoria's endangered Leadbeaters possum, Gymnobelideus leadbeateri , the closest living relative of the dactylopsilinae (Osborne & Christidis 2001).…”

The New Guinean endemic dactylopsilines are members of the Petauridae possum family, represented in Australia only by the striped possum Dactylopsila trivirgata. The shy nature and low density of this species have hampered studies of its ecology to date, so we developed nine highly variable polymorphic microsatellite markers to enable molecular genetic analysis of population structure and mating system parameters. This will add substantially to our understanding of the behavioural ecology of this species. The low degree of cross‐amplification of the primers in other petaurid species lends weight to other evidence suggesting that this family underwent a relatively early radiation.
