Boom and bust: a review of the physiology of the marsupial genus Antechinus
The marsupial genus Antechinus is a group of small carnivorous marsupials from the order Dasyuromorphia (Family Dasyuridae) and is found in eastern Australia. The life history of all species in the genus is chara...

Effect of torpor on the water economy of an arid-zone marsupial, the stripe-faced dunnart (Sminthopsis macroura)
Metabolic rate and evaporative water loss (EWL) were measured for a small, arid-zone marsupial, the stripe-faced dunnart (Sminthopsis macroura), when normothermic and torpid. Metabolic rate increased linearly wit...

Effects of temperature acclimation on maximum heat production, thermal tolerance, and torpor in a marsupial
Marsupials, unlike placental mammals, are believed to be unable to increase heat production and thermal performance after cold-acclimation. It has been suggested that this may be because marsupials lack functi...

The effects of cortisol and testosterone on renal function in male Antechinus stuartii (Marsupialia)
Seasonal changes in the physiology of Antechinus stuartii result in complete male mortality after mating. The most important endocrine changes in males are large rises in plasma testosterone and cortisol concent...

Seasonal changes in glomerular filtration rate in Antechinus stuartii (Marsupialia: Dasyuridae)
The small marsupial Antechinus stuartii experiences a synchronised life cycle that culminates in complete male mortality (within 3 weeks) following the 1 week mating period in mid-August (late winter). There are...

The degree of dietary fatty acid unsaturation affects torpor patterns and lipid composition of a hibernator
Diets rich in unsaturated and polyunsaturated fatty acids have a positive effect on mammalian torpor, whereas diets rich in saturated fatty acids have a negative effect. To determine whether the number of doub...
