Climate change will drastically reduce the range of African great apes over the next 30 years. This was predicted by an international team of researchers with the participation of the German Centre for Integrative Biodiversity Research, the Max Planck Institute for Evolutionary Anthropology and the Martin Luther University Halle-Wittenberg. In various models, they calculated the effects of climate change, changing land use and human population growth on the future range of gorillas, chimpanzees and bonobos. The existing protected areas are not sufficient to preserve important populations in the long term, the researchers warn.
