What is it about?
Mammals in the African savanna change water bodies when they visit them to drink. The resulting waters are highly diverse and serve as spawning grounds for amphibians and other animals. The change of the amphibian community in the West African savanna after the decline of the mammals was investigated. It was found that some amphibian species have hardly been affected in their abundance, while others have become rare or have disappeared completely.

Why is it important?
Most amphibian species of the West African savanna prefer special microhabitats in their spawning waters. If these are lost, only some species are able to switch to other microhabitats. Highly specialized species become extinct. Presumably, however, the decline of some species is not solely due to structural changes in the spawning waters.
