As timber companies move into Central Africa’s forests, apes increasingly have to find ways to survive in the altered forests they call home. Scientists still don’t know the full impact of logging on many animals, but now a new study suggests that gorillas stand a better chance of adapting to thinned-out forests than chimpanzees. The research, published Nov. 26 in the journal Biological Conservation, finds that logging initially drives out both western lowland gorillas and central chimpanzees. But later on, the unique ways in which each species reacts leads to a divergence in their responses. “Because gorillas aren’t territorial, they’ll slip right back into those areas and groups will feed relatively close to each other,” Dave Morgan, a biologist with the Lincoln Park Zoo and an author of the study, said in an interview.
