Every year, thousands of drowned wildebeest feed this African ecosystem [Science]
It’s one of the iconic sights of Africa : hundreds of thousands of wildebeest thundering across the Serengeti in an annual mass migration. But when the animals come to the Mara River, the scene can turn deadly. Unable to scramble up steep banks, thousands drown in a mass panic or get picked off by crocodiles. It turns out, however, that what’s bad for the wildebeest is good for the ecosystem, say Amanda Subalusky and Emma Rosi, ecologists at the Cary Institute of Ecosystem Studies in Millbrook, New York.

Birds of all feathers work together to hunt when army ants march [Phys]
Army ants scare up a lot of food when they’re on the move, which makes following them valuable for predator birds. But instead of competing and chasing each other off from the ant "raids," as scientists had thought, birds actually give each other a heads up when the ants are marching, according to a new Drexel University study.
