The finding that numbers of gorillas and chimpanzees appear to have dwindled twice as much near towns in Gabon than near villages supports a focus on conservation efforts that tackle commercial hunting over those that aim to convince villagers to give up subsistence hunting, says Hjalmar Kühl at the Max-Planck-Institute for Evolutionary Anthropology in Leipzig, Germany, who conducted the study with colleagues.
The problem with estimating the impact of ape hunting just from watching local markets and hunters, he explains, is that this reveals little about how the population may be suffering as a whole. "We rarely find ape meat in the markets, but these animals are already so rare and reproduce so slowly that even comparatively low-level hunting might do a lot of damage," he says."
