Penguins tracked amid climate change fears
Genetic ''featherprints'' are being used to map the movements of penguins and see how they are affected by global warming.
Dr Tom Hart, one of the scientists from the Zoological Society of London (ZSL), said: ''Knowing how penguins are responding to climate change is vital to conservation efforts. If we understand how their populations are changing, we can do something about it, such as making sure that our protected areas are in the right place for penguins in 100 years' time.''
Penguins are not only threatened by climate change, but are also under increasing pressure from fisheries that take their food. Studying them is notoriously difficult because they live in very harsh environments and are hard to track.
Dr Hart is launching a series of expeditions to gather feather samples and plot the movement of penguins around the Southern Ocean.
