Terrestrial small mammal diversity and abundance in central Benin: Comparison between habitats, with conservation implications.

Résumé

We performed a terrestrial small mammal species inventory in the Agoua and Wari-Maro forest reserves (Benin). Four localities were sampled, and in each locality, three habitats were surveyed: dense forest, open forest or woodland savannah and shrub savannah. This is the first comprehensive inventory for small mammals in central Benin. We captured 794 small mammals representing twenty species (six shrew species, fourteen rodent species). Three new species that need to be described were recorded. We observed a mixture of both true forest species and of species adapted to a wider range of habitats ranging from savannah to forest clearings. Species with either Sudanian or Guinea–Congolian affinities were recorded, as well as a new species endemic to Togo and Benin. This rich biodiversity underlines the urgent need for an effective protection of these forests. The Sudanian species Crocidura cf. foxi was more abundant in Wari-Maro than in Agoua forest, while the Guineo–Congolian species Praomys misonnei and Hylomyscus sp were only captured in Agoua forest. These results are in agreement with the fact that these two forests belong to two distinct chorological zones.
