Systematic Reviews of New Guinea Coccymys and “Melomys” Albidens (Muridae, Murinae) with Descriptions of New Taxa
A degree of morphological divergence is revealed not only from species in Coccymys but from any other “Old Endemic” New Guinea murine, and a new genus, Brassomys, sampled by only six modern specimens and three Late Pleistocene fossils, is proposed to embrace albidens. Expand
Skull shape of a widely distributed, endangered marsupial reveals little evidence of local adaptation between fragmented populations
3D geometric morphometrics is used to characterize shape diversity in the skull of an endangered marsupial, the northern quoll, across its 5,000 km distribution range along Northern Australia and concludes that it can provide a comprehensive, statistically rigorous phenomic contribution to genetic‐based conservation studies. Expand
Discovered and disappearing? Conservation genetics of a recently named Australian carnivorous marsupial
Australia's buff‐footed antechinus is limited to a more scattered and fragmented distribution than previously thought and may be in decline, and the extinction risk of many Australian mammals should be reassessed. Expand
Phylogenetic Relationships of the Dasyurid Marsupial Genus Murexia
Results from an expanded DNA sequence data set that includes 2 additional mitochondrial loci and 2 nuclear loci from phascogalin species and selected dasyurid and myrmecobiid outgroups are reported, providing the 1st resolved phylogeny of Murexia and Antechinus species. Expand
Total evidence phylogeny and evolutionary timescale for Australian faunivorous marsupials (Dasyuromorphia)
The first total evidence phylogenetic analyses of the order Dasyuromorphia are presented, based on combined morphological and molecular data, to resolve relationships and calculate divergence dates, which provide a phylogenetic and temporal framework for interpreting the evolution of modern and fossil dasyuromorphians. Expand
The Black-tailed Antechinus, Antechinus arktos sp. nov.: a new species of carnivorous marsupial from montane regions of the Tweed Volcano caldera, eastern Australia.
A new species of dasyurid marsupial within the genus Antechinus that was previously known as a northern outlier of Duskyantechinus is described, which has plausibly been detrimentally affected by climate change in recent decades, and will be at further risk with increasing warming trends. Expand
The endemic New Guinean genus Murexia (Dasyuromorphia : Dasyuridae). How many species? An analysis based on morphological, distributional and molecular data
Morphological data, including spacing of premolar teeth, the footpads and aspects of external appearance, together with nuclear and mitochondrial DNA sequences from multiple exemplars from across the range of each species, suggest that at least three of these represent species groups rather than individual species. Expand
The type specimen of Murexia longicaudata (Dasyuromorphia : Dasyuridae): an enigma
The holotype of Murexia longicaudata is either a highly abnormal individual or that the skull and dentaries are mismatched, and the dentaries may be those of a smaller individual. Expand
An emerging consensus in the evolution, phylogeny, and systematics of marsupials and their fossil relatives (Metatheria)
Marsupials and their fossil relatives, which collectively comprise Metatheria, have been of scientific interest for centuries, with many aspects of their evolution and systematics subject to intenseExpand
Male members of some endemic New Guinean dasyurid marsupials: they help resolve relationships
Penis morphology of 12 species of endemic New Guinean dasyurid marsupials, including the five currently recognized species of Murexia (M. habbema, M. melanurus, M. naso, M. longicaudata, and M.Expand
