Two hundred and thirty-six mitochondrial DNA nucleotide sequences were used in combination with polymorphism at four nuclear microsatellite loci to assess the amount and distribution of genetic variation within and between African savannah elephants. They were sampled from 11 localities in eastern, western and southern Africa. In the total sample, 43 haplotypes were identified and an overall nucleotide diversity of 2.0% was observed. High levels of polymorphism were also observed at the microsatellite loci both at the level of number of alleles and gene diversity. Nine to 14 alleles per locus across populations and 44 alleles in the total sample were found. The gene diversity ranged from 0.51 to 0.72 in the localities studied. An analysis of molecular variance showed significant genetic differentiation between populations within regions and also between regions. The extent of subdivision between populations at the mtDNA control region was approximately twice as high as shown by the microsatellite loci (mtDNA FST = 0.59; microsatellite RST = 0.31). We discuss our results in the light of Pleistocene refugia and attribute the observed pattern to population divergence in allopatry accompanied by a recent population admixture following a recent population expansion.
I saw a short documentary about a year ago about this. It related to ivory poachers using the difference in DNA as a defense, something along the lines of "But it's not the protected species -- just do a DNA test and you'll see!" Maybe now
both species can be officially protected.
