Each year, thousands of wildebeest drown while making their annual migration through the Serengeti. New research shows how the resulting 1100 tonnes of rotting flesh performs a crucial role in maintaining the region's vibrant ecosystem.
Camera traps set up in Utah's Great Basin Desert have captured unprecedented behaviour showing a badger burying an entire cow by itself. Incredibly, the buried carcass was able to sustain the badger for months.
Researchers working in Africa are the first to observe monkeys preying on bats. The unusual behaviour, which may have something to do with loss of habitat, could explain how dangerous diseases such as Ebola spread among species -- and eventually to humans.
