The anatomy of mastication in a toothless mammal: Morphological characteristics of the temporomandibular joint in the platypus (<i>Ornithorhynchus anatinus</i>) Open
The temporomandibular joint (TMJ) is a distinguishing feature of mammals, and in most mammals includes an articular disc that buffers the loads placed on it by mastication. The disc is well developed in mammals with significant lateral mas…

Pollination of <i>Richea dracophylla</i> (Ericaceae) and the role of the nocturnal ant <i>Notoncus hickmani</i> (Formicinae) Open
Our observation of large numbers of ants Notoncus hickmani (Formicinae) on the flowers of a Tasmanian endemic shrub Richea dracophyllum (Ericacea) during the night in winter prompted us to carry out a more extensive study of pollination of…

Metabolism and temperature regulation in Marsupials with particular reference to the potoroo, potorous tridactylus apicalis Gould. Open
In an attempt to clarify aspects of thermoregulation and metabolism in marsupials a detailed investigation was made of the potoroo. Measurements of activity, oxygen consumption, creatinine excretion and total urinary nitrogen excretion of …

Population demography of the Tasmanian short-beaked echidna (Tachyglossus aculeatus) Open
Deriving estimates of demographic parameters and the processes driving them is crucial for identifying wildlife management options. The short-beaked echidna (Tachyglossus aculeatus) is the most widely distributed native Australian mammal, …

Energetics meets sexual conflict: The phenology of hibernation in Tasmanian echidnas Open
Echidnas are egg‐laying mammals found across Australia, and in Tasmania they hibernate, resulting in a most unusual mating system: males enter hibernation in late summer–early autumn and arouse in late autumn–early winter to mate, although…

Energy Homeostasis in Monotremes Open
In 1803, the French anatomist Étienne Geoffroy Saint-Hilaire decided that the newly described echidna and platypus should be placed in a separate order, the monotremes, intermediate between reptiles and mammals. The first physiological obs…

Reexamining Echidna Physiology: The Big Picture for<i>Tachyglossus aculeatus acanthion</i> Open
The early divergence of monotremes and therian mammals has resulted in considerable interest in the comparative physiology of the short-beaked echidna (Tachyglossus aculeatus), the most common and widespread living monotreme. However, ther…

Interaction of hibernation and male reproductive function in wild Tasmanian echidnas<i>Tachyglossus aculeatus setosus</i> Open
The short-beaked echidna Tachyglossus aculeatus is a seasonally breeding mammal with a near ubiquitous distribution throughout Australia. In Tasmania, breeding follows a period of deep hibernation, and males begin mating approxima…

Testing the Role of Climate Change in Species Decline: Is the Eastern Quoll a Victim of a Change in the Weather? Open
To conserve a declining species we first need to diagnose the causes of decline. This is one of the most challenging tasks faced by conservation practitioners. In this study, we used temporally explicit species distribution models (SDMs) t…

Devil Declines and Catastrophic Cascades: Is Mesopredator Release of Feral Cats Inhibiting Recovery of the Eastern Quoll? Open
The eastern quoll (Dasyurus viverrinus) is a medium-sized Australian marsupial carnivore that has recently undergone a rapid and severe population decline over the 10 years to 2009, with no sign of recovery. This decline has been linked to…
