Dr Ned Snelling, Senior Lecturer in the Department of Anatomy and Physiology and Prof Leith Meyer, Director of the Centre for Veterinary Wildlife Studies, both from the Faculty of Veterinary Science have just published a new study on the welfare and survival of Africa’s arid-dwelling mammals under the threat of climate change.
The pair teamed up with their Brain Function Research Group (BFRG) collaborators at Wits University to show how mammals will need to contend not only with increasing heat loads into the future, but also reduced water and food availability, a situation that will compromise their ability to regulate body temperature. The authors explain how a lack of water will suppress evaporative cooling during the day, while a lack of food will limit metabolic heat production at night, leading to body temperature irregularities, physiological malfunction and possible death.
The publication has appeared in a special themed issue - "Predicting the Future: Species Survival in a Changing World" - of the Journal of Experimental Biology with a once-off free access. To access and view the study/abstract please click here.

Nine new trapdoor spider species have been discovered in the Great Karoo by researchers at the University of Pretoria’s (UP) Department of Zoology and Entomology, and the Agricultural Research Council (ARC).
Trapdoor spiders hide in underground burrows that are covered with a cork-like lid made of soil, silk and plants. Learn more about trapdoor spiders with this infographic.
Watch carefully to see how a trapdoor spider catches its prey through its trapdoor.
