body temperature, and surface areas of Australian marsupials. 1970.-Standard (basal) metabolism and resting body temperatures were measured in eight Australian marsupial species which ranged in weight from 9 g to 54 kg. The relationship between standard metabolic rate (SMR) and body weight (W) was found to be best represented by the equation SMR (cal/hr) =(More)

Physiol. 227(Z) : 494498. 1974.-The red kangaroo (Megaleia rufa) uses three evaporative cooling mechanisms : panting, sweating, and saliva spreading. Sweating only occurs during exercise.

To determine whether marsupial mammals increase their metabolic capabilities during cold acclimation, the metabolism of both warm and cold acclimated Dasyuroides byrnei was examined by exposure to cold in a helium-oxygen atmosphere. Mean values of heat production and conductance were significantly higher in a helium-oxygen atmosphere than in air. Body(More)
1. Monodelphis domestica is a small marsupial mammal from South America. Its thermogenic abilities in the cold were determined when the opossums were both warm (WA) and cold (CA) acclimated. Maximum heat production of M. domestica was obtained at low temperatures in helium-oxygen. 2. Basal metabolic rate (BMR) in the WA animals was 3.2 W/kg and mean body(More)
A cholera epidemic that took place in KwaZulu-Natal, South Africa (2000-2001) was employed to investigate the impact of climatic and environmental drivers on cholera dynamics. Precipitation (PRE), sea surface temperature (SST) and chlorophyll-a (CHL-a) data acquired from publicly available satellite and ground measurements were analysed together with(More)
