The world mourns the loss of Malaysia's last male Sumatran rhino. Can anything stop the slide of the species towards extinction?
When people build fences across semi-arid landscapes we cut off vital paths to seasonal food and water.
Camera traps allow citizen scientists to peek into the hidden lives of Britain's mammals.
Our flippered friends evolved from small, hooved deer-like creatures more than 50m years ago.
Trackways made by vertebrates during the Pleistocene era, dating back to between 36 000 and 140 000 years helps with research into ancient animals.
A look at new research published in 2018 on fossa, deepsea corals and tropical frogs developing resistance to a deadly fungus.
A survey of 32,000 samples of dingo droppings and stomach contents reveal that this predator's appetite is as wide-ranging as Australia's landscapes. But medium and large mammals are top of the menu.
Finding a mate is of course essential to produce the next generation. And feathers and fur play key roles in making sure that happens.
Our study used innovative 3D scanning and engineering-inspired computer simulations to understand the evolution of the penis bone in some mammals.
The koala genome, published today, gives us new and valuable information to aid conservation of this marsupial. It identifies special genes that evolved to adapt the koala to its unique lifestyle.
'Molecular fossils' in the DNA of elephants could help explain why their testicles are inside their bodies.
It's becoming harder and harder for animals to find human-free spaces on the planet. New research suggests that to try to avoid people, mammals are shifting activity from the day to the nighttime.
Camera traps in the Batéké Plateau National Park in Gabon are showing some interesting finds.
Mating in southern African pythons is a serious business, and is rarely just a one-night stand
