A new series of maps drawn up by Emeritus Professor Rudi van Aarde of the University of Pretoria (UP) and Dr Ryan Huang of Duke University in the US details where African elephants prefer to roam in Southern Africa.
This gallery features photography of elephants in their natural habitat by Prof Rudi van Aarde and a map showing where their preferred areas are based on the elephants' movement patterns.
The Southern Ocean around Antarctica needs urgent protection – for the sake of the rest of the world. This marine wilderness is threatened by climate change and commercial fisheries, says University of Pretoria (UP) macro-ecologist Dr Luis Pertierra, an expert on the natural value of the Antarctic.
Did you know that 70% of the world's freshwater is held in Antarctica's ice? This is just one of the reasons why the Southern Ocean around Antarctica needs urgent protection. Learn more Southern Ocean facts with this infographic.
Climate change and commercial fishing is putting Earth’s most southern waters – and the planet itself – at risk. UP macro-ecologist Dr Luis Pertierra has joined the global call to better protect the Southern Ocean by banning fishing in Antarctic waters, among other measures.
Rising temperatures as a result of climate change will affect bird species differently, and their abilities to withstand extremely hot conditions depend on the part of the world that they find themselves in and the climatic region to which their physiology has become adapted over the course of millennia.
Birds such as pygmy kingfishers and collared sunbirds that are found in hot, humid climates can handle larger spikes in body temperature better than bird species flying about in hot deserts or cool mountains.
University of Pretoria researchers Dr Mariëtte Pretorius and Professor Wanda Markotter have published a study which shows that land around important bat-inhabited caves are changing and that natural habitats are being destroyed.
This gallery takes you on a field trip with scientists as they monitor bat health and species diversity. You can see what bats really look like up close and in full flight.
