The external ear morphology and presence of tragi in Australian marsupials

open access: yesEcology and Evolution, 2020
Multiple studies have described the anatomy and function of the external ear (pinna) of bats, and other placental mammals, however, studies of marsupial pinna are largely absent.

Assessing the potential for intraguild predation among taxonomically disparate micro-carnivores: marsupials and arthropods [PDF]

open access: yesRoyal Society Open Science, 2018
Interspecific competition may occur when resources are limited, and is often most intense between animals in the same ecological guild. Intraguild predation (IGP) is a distinctive form of interference competition, where a dominant predator selectively ...

Expansion of CORE-SINEs in the genome of the Tasmanian devil [PDF]

open access: yes, 2012
Background: The genome of the carnivorous marsupial, the Tasmanian devil (Sarcophilus harrisii, Order: Dasyuromorphia), was sequenced in the hopes of finding a cure for or gaining a better understanding of the contagious devil facial tumor disease that ...

Ecomorphological determinations in the absence of living analogs:The predatory behavior of the marsupial lion (Thylacoleo carnifex) as revealed by elbow joint morphology [PDF]

open access: yes, 2016
Thylacoleo carnifex, or the “pouched lion” (Mammalia: Marsupialia: Diprotodontia: Thylacoleonidae), was a carnivorous marsupial that inhabited Australia during the Pleistocene.

Sexual selection of protamine 1 in mammals [PDF]

open access: yes, 2015
Protamines have a crucial role in male fertility. They are involved in sperm chromatin packaging and influence the shape of the sperm head and, hence, are important for sperm performance.

Macrogeographic Variation in Litter Size in Antechinus (Marsupialia: Dasyuridae) [PDF]

open access: yesEvolution, 1983
The best documented cases of geographic variation in brood size are the tendency of avian clutches to increase with latitude (Lack, 1947, 1954; Klomp, 1970), and mammalian litters to increase with both latitude (Lord, 1960), and altitude (Dunmire, 1960; Fleming and Rauscher, 1978; Bronson, 1979).

Temporal and spatial distribution of the Tasmanian Devil, Sarcophilus harrisi (Dasyuridae: Marsupialia) [PDF]

open access: yes, 1982
The Tasmanian devil Sarcophilus harrisi(Boitard), once widespread on continental Australia, probably became extinct there partly due to food competition with dingoes and, possibly, black man and their extinction may have been expedited by a dry climatic ...

Extreme Telomere Length Dimorphism in the Tasmanian Devil and Related Marsupials Suggests Parental Control of Telomere Length [PDF]

open access: yes, 2012
Telomeres, specialised structures that protect chromosome ends, play a critical role in preserving chromosome integrity. Telomere dynamics in the Tasmanian devil (Sarcophilus harrisii) are of particular interest in light of the emergence of devil facial ...

Can evolutionary theories of dispersal and senescence predict postrelease survival, dispersal, and body condition of a reintroduced threatened mammal?

open access: yesEcology and Evolution, 2021
Theories of dispersal and senescence (or aging) predict that dispersal, and ongoing survival and body condition, are influenced by evolutionary drivers, along with intrinsic and extrinsic factors.

Embryology of the fat-tailed dunnart (Sminthopsis crassicaudata): A marsupial model for comparative mammalian developmental and evolutionary biology. [PDF]

open access: yesDev Dyn
Abstract Background Marsupials are a diverse and unique group of mammals, but remain underutilized in developmental biology studies, hindering our understanding of mammalian diversity. This study focuses on establishing the fat‐tailed dunnart (Sminthopsis crassicaudata) as an emerging laboratory model, providing reproductive monitoring methods and a ...
