Movement of Free-Ranging Koalas in Response to Male Vocalisation Playbacks

open access: yesAnimals, 2022
Effective conservation strategies rely on knowledge of seasonal and social drivers of animal behaviour. Koalas are generally solitary and their social arrangement appears to rely on vocal and chemical signalling.

Marsupial chromosome DNA content and genome size assessed from flow karyotypes: invariable low autosomal GC content [PDF]

open access: yesRoyal Society Open Science, 2018
Extensive chromosome homologies revealed by cross-species chromosome painting between marsupials have suggested a high level of genome conservation during evolution.

Pouch bacteria: an understudied and potentially important facet of marsupial reproduction [PDF]

open access: yesMicrobiology Australia, 2023
Australia is home to a rich biodiversity of marsupials that are found nowhere else. Unfortunately, many of these species are currently threatened with extinction due to introduced feral predators and other anthropogenic factors.

Letting the ‘cat’ out of the bag: pouch young development of the extinct Tasmanian tiger revealed by X-ray computed tomography [PDF]

open access: yesRoyal Society Open Science, 2018
The Tasmanian tiger or thylacine (Thylacinus cynocephalus) was an iconic Australian marsupial predator that was hunted to extinction in the early 1900s.

The common black-eared opossum in the symbolic and iconographic universe. From the effigy ornaments in the lesser Antilles to the European graphics of Simivulpa and its variants in the 16th – 17th centuries

open access: yesCiencia y Sociedad, 2023
This study focuses on the aesthetic analysis, iconographic variants, and symbolism of the common black-eared opossum (Didelphis marsupialis Linnaeus 1758) in ceramic ornaments of agro-ceramic origin of the Saladoid tradition with Barrancoid influence ...

Trichromacy in Australian Marsupials [PDF]

open access: yesCurrent Biology, 2002
Vertebrate color vision is best developed in fish, reptiles, and birds with four distinct cone receptor visual pigments. These pigments, providing sensitivity from ultraviolet to infrared light, are thought to have been present in ancestral vertebrates.

The evolutionary process of mammalian sex determination genes focusing on marsupial SRYs

open access: yesBMC Evolutionary Biology, 2018
Background Maleness in mammals is genetically determined by the Y chromosome. On the Y chromosome SRY is known as the mammalian male-determining gene. Both placental mammals (Eutheria) and marsupial mammals (Metatheria) have SRY genes.

A Marsupial Oncovirus?

open access: yesJournal of General Virology, 1979
A virus-like particle was observed in two continuous cell lines derived from the marsupial Sminthopsis crassicaudata (Fat-tailed Dunnart). The development of the particle was similar to the development of D-type oncoviruses. Initially, a crescentof nucleoid material was observed near the nucleus in the region of the Golgi apparatus.

Is Toxoplasma gondii a threat to the conservation of free-ranging Australian marsupial populations?

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2016
It has often been asserted that Australian marsupial species are particularly susceptible to Toxoplasma gondii infection and to clinical toxoplasmosis following infection. This implicates T. gondii as a potential threat to marsupial population viability,

Genome sequence of an Australian kangaroo, Macropus eugenii, provides insight into the evolution of mammalian reproduction and development. [PDF]

open access: yes, 2011
BACKGROUND: We present the genome sequence of the tammar wallaby, Macropus eugenii, which is a member of the kangaroo family and the first representative of the iconic hopping mammals that symbolize Australia to be sequenced.
