Abstract:   (8380 Views)
There is an increased recognition of the threat status of the African lion (Panthera leo), once a widespread top predator of open African habitats. However, our knowledge about the biology of the species is often based on a few study sites in South and East Africa, and the present subspecific taxonomy developed by the IUCN reinforces an idea of homogeneity of the species in Africa. A synthesis of available knowledge regarding the lions of Southern Somalia, formerly proposed as a distinct subspecies, Panthera leo somaliensis is presented. Particular attention is paid to the issue of manelessness in males, a phenomenon that has been studied in Tsavo (N.E. Kenya) but it is highlighted for the first time for the Southern Somalia region. Although our data cannot lead to a definitive answer about the taxonomic status of Somali lions, there is enough evidence to call for further studies and conservation efforts, also in the light of the increased evidence of genetic discontinuity in lions associated with strong ecological barriers.
