摘要

Times are grim for the king of the beasts. Roughly 35,000 African lions roam the savannahs, down from more than 100,000 half a century ago, thanks to habitat loss, declining numbers of prey animals and killing by humans. One study estimated that fewer than 50 lions (Panthera leo) live in Nigeria and reported no sign of the animal in the Republic of the Congo, Ghana or Cote d'lvoire. Now a king-sized controversy is brewing over a proposal to shore up lion populations before it is too late. A prominent lion researcher has called for limiting conflict between humans and lions by erecting fences around reserves containing wild lions. The idea has split scientists, with those opposed to the idea arguing that fences could do more harm than good. The ensuing debate has also laid bare fundamental differences of opinion about how to preserve lions and other species, and raised concerns that a key challenge to lion conservation - lack of funds - is being ignored while scientists trade jabs about fences.
