Editor's choice: endangered species
WWF reports that between 10,000 and 100,000 species are disappearing every year. Many more are on the verge of becoming extinct; and among those are a number of charismatic megafauna species, whose survival - despite the best efforts - is anything but sure. We can only help those species as much as we understand them. This collection therefore presents the best of research providing insights into the biology of such endangered animal species, including apes, big cats, and others.
