Growing sabers: Mandibular shape and biomechanical performance trajectories during the ontogeny of Smilodon fatalis

open access: yesThe Anatomical Record, Volume 308, Issue 11, Page 2976-2993, November 2025.
Abstract The evolution of organisms can be studied through the lens of developmental systems, as the timing of development of morphological features is an important aspect to consider when studying a phenotype. Such data can be challenging to obtain in fossil amniotes owing to the scarcity of their fossil record. However, the numerous remains of Rancho

Complex associations between cancer progression and immune gene expression reveals early influence of transmissible cancer on Tasmanian devils

open access: yesFrontiers in Immunology
The world’s largest extant carnivorous marsupial, the Tasmanian devil, is challenged by Devil Facial Tumor Disease (DFTD), a fatal, clonally transmitted cancer. In two decades, DFTD has spread across 95% of the species distributional range.

Baylisascaris tasmaniensis sp.nov. in marsupial carnivores: heirloom or souvenir?

open access: yesParasitology, 1970
A new species of ascaridoid nematode, Baylisascaris tasmaniensis, is described from three marsupial carnivores of Tasmania, namely Sarcophilus harrisi, Dasyurus viverrinus, and Dasyurops maculatus. The new species is differentiated from other species in the genus Baylisascaris and the phylogenetic affinities within the genus are discussed in relation ...

Evolutionary Biology of the Australian Carnivorous Marsupial Genus Antechinus [PDF]

open access: yes, 2017
Antechinus is an Australian genus of small carnivorous marsupials. Since 2012, the number of described species in the genus has increased by 50% from ten to fifteen. The systematic relationships of these new species and others in the genus have not been well resolved and a broad phylogeographic study of the genus is lacking. Moreover, little ecological

Population dynamics of desert mammals: similarities and contrasts within a multispecies assemblage

open access: yesEcosphere, 2016
Understanding the temporal and spatial dynamics of species populations remains a key focus of population biology, providing vital insight into the drivers that influence demography and into sub‐populations that are vulnerable to extinction.

Uniformity in the basal metabolic rate of marsupials: its causes and consequences Uniformidad en la tasa metabólica basal de marsupiales: sus causas y consecuencias

open access: yesRevista Chilena de Historia Natural, 2005
Most of the variation (98.8 %) in basal rate of metabolism (BMR) in 70 species of marsupials is correlated with body mass, although lowland species have higher basal rates than highland species and burrowers have lower basal rates than non-burrowers ...

Who's on the menu : marsupial carnivore feeding ecology and extinction risk

open access: yes, 2013
The aim of this thesis is to assess the role of diet in the extinction of Australia's iconic marsupial carnivore, the thylacine (Thylacinus cynocephalus) in Tasmania. Herein, we present two novel techniques to address fundamental questions regarding their maximum prey size and potential competition with sympatric predators.
