The origin, current diversity and future conservation of the modern lion (Panthera leo)

摘要: Understanding the phylogeographic processes affecting endangered species is crucial both to interpreting their evolutionary history and establishment of conservation strategies. Lions provide a key opportunity explore such processes; however, lack genetic diversity shortage suitable samples has until now hindered investigation. We used mitochondrial control region DNA (mtDNA) sequences investigate modern lions, using from across entire range. find sub-Saharan African lions are basal among supporting single origin model lion evolution, equivalent ‘recent origin’ human evolution. also greatest variety mtDNA haplotypes in centre Africa, which may be due distribution physical barriers continental-scale habitat changes caused by Pleistocene glacial oscillations. Our results suggest that currently consist three geographic populations on basis recent history: North African–Asian, southern middle African. Future strategies should take these subdivisions into consideration.
