The rainforest block of southwestern Nigeria constitutes a unique ecosystem. It is also home to a rich small mammal community, for which the taxonomic composition, taxonomic richness and geographic distribution may serve as appropriate indicators of the evolutionary history and conservation status of this important segment of African biodiversity.

Much of the inferences and hypotheses concerning the character of this ecosystem have been drawn in the past from comparative morphological grounds. Today, however, the advent of molecular biology has begun to provide data and insights that are leading to the refinement, or rebuttal in some cases, of these morphological inferences. This new book discusses these developments such as they affect rodents and other small mammals in Southwestern Nigeria. (Imprint: Nova Biomedical)
