Abstract
  • Peer-reviewed studies on the community structure of small mammals (Rodentia and Soricomorpha) from the Gulf of Guinea region of West Africa were reviewed. To detect nonrandom patterns in the various assemblages under study, the original datasets were re-analysed using null models [two independent randomization algorithms (RA) for niche overlap] and Monte Carlo simulations. The total species richness in the countries considered in this review was 45 species for soricomorphs and 101 for rodents, and the studies reviewed here reported data for 53.3% of these soricomorph species and for 76.2% of these rodent species. Nonrandom habitat niche partitioning was rarely observed in both rodents and soricomorphs. Instead, aggregated use of habitat resources was frequently detected in both groups. Forest habitat was generally selected as aggregating resource type by small mammal assemblages. Thus, contrary to expectations, our review revealed little evidence for interspecific competition along the habitat niche axis in West African small mammals. However, it is possible that the aggregated use of the forest resource by small mammal species may be apparent, but that the various species partitioned space at a lower scale, for instance selecting different microhabitats. Interspecific competition appeared to be stronger in altered habitats, as predicted by previous studies on other forest organisms in West Africa. (literal)
