Bats in Africa may keep a suitable climate but lose roosts
Researchers at the University of Pretoria modelled where cave-roosting long-fingered bats could live in sub-Saharan Africa. They project that climatically suitable areas will shrink by 36% to 64% by 2061 to 2080.
The study by Pretorius and Keith appears in the peer-reviewed journal Austral Ecology. Only about 5% of the karst that suits roosts overlaps with the suitable future climate. That falls to about 2% once the model counts the vulnerability of land cover. This shows that a species can have a suitable climate ahead and still have nowhere to roost, because the geology has no caves. The work is a model of one bat family, based on 551 occurrence records.
