Resting disparity in quoll semelparity: examining the sex-linked behaviours of wild roaming northern quolls (Dasyurus hallucatus) during breeding season [PDF]

Royal Society Open Science, 2023
Semelparity is a breeding strategy whereby an individual invests large amounts of resources into a single breeding season, leading to the death of the individual.

A Burst of Numt Insertion in the Dasyuridae Family During Marsupial Evolution

Frontiers in Ecology and Evolution, 2022
Nuclear pseudogenes of mitochondrial origin (numts) are common in all eukaryotes. Our previous scan of numts in sequenced nuclear genomes suggested that the highest numt content currently known in animals is that in the gray short-tailed opossum.

Factors Affecting Multiple Paternity: Insights From the Eastern Quoll (Dasyurus viverrinus) [PDF]

Ecology and Evolution
Breeding systems influence population dynamics and genetic diversity, especially when a population is small or isolated. To examine population‐level drivers of multiple paternity, we combined long‐term demographic data and 1745 single‐nucleotide ...

Postnatal development in a marsupial model, the fat-tailed dunnart (Sminthopsis crassicaudata; Dasyuromorphia: Dasyuridae) [PDF]

Communications Biology, 2021
Cook, Pask and colleagues describe the ossification of the skull and forelimbs in the developing postnatal fat-tailed dunnart. As one of the most altricial marsupials at birth with a short reproductive cycle and simple lab husbandry, this species is a ...

The mitochondrial genome of the black-tailed dusky antechinus (Antechinus arktos) [PDF]

Mitochondrial DNA. Part B. Resources, 2020
In this study, we report the mitochondrial genome of the black-tailed antechinus (Antechinus arktos), a recently-discovered, endangered carnivorous marsupial inhabiting a caldera that straddles the border of Australia’s mid-east coast.

Meiotic dynamics in a unique Australian marsupial provide new insights into the evolution of neo-sex chromosomes in the early stages of differentiation [PDF]

Frontiers in Cell and Developmental Biology
Understanding the origin and fate of sex chromosomes has been one of the most intriguing questions in biology. In therian (marsupial and eutherian) mammals, most species are characterized by a heteromorphic XX female XY male sex chromosome system.

Cryptic Kultarr: Integrative Taxonomy Reveals Unrecognized Species of Carnivorous Marsupial (Dasyuridae: Antechinomys) in Arid Australia [PDF]

Ecology and Evolution
Globally, mammal species are experiencing unprecedented rates of extinction. Despite this, many small mammals remain understudied and even undescribed, posing a major barrier to effective conservation planning.

The mitochondrial genome of the black-tailed dasyure (Murexia melanurus) [PDF]

Mitochondrial DNA. Part B. Resources, 2019
In this study, we report the mitochondrial genome of the black-tailed dasyure (Murexia melanurus) of New Guinea. The circular genome is 17,736 bp in length and has an AT content of 60.5%.

Total evidence phylogeny and evolutionary timescale for Australian faunivorous marsupials (Dasyuromorphia) [PDF]

BMC Evolutionary Biology, 2017
Background The order Dasyuromorphia is a diverse radiation of faunivorous marsupials, comprising >80 modern species in Australia and New Guinea. It includes dasyurids, the numbat (the myrmecobiid Myrmecobius fasciatus) and the recently extinct thylacine (

Comparing Methods of Detecting an Elusive Dasyurid Marsupial, the Threatened Julia Creek Dunnart (Sminthopsis douglasi), in Central Western Queensland, Australia [PDF]

Ecology and Evolution
The Julia Creek dunnart, Sminthopsis douglasi, is a small, threatened carnivorous marsupial occurring in scattered populations in the grasslands of central and northwestern Queensland, Australia.
