Biochemical systematics of elephant shrews from Southern Africa
摘要:
The biochemical systematics of seven species of elephant shrews from southern Africa, based on allozyme variation and chromosomal analyses, was examined and compared to phylogenies based on morphological analyses. In addition, populations within three species, Elephantulus intufi, E. rupestris and E. myurus, were analysed for intrapopulational genetic variation. Both genetic and morphological data sets showed that all five species of Elephantulus examined were more closely related to each other than to either Petrodromus tetradactylus or Macroscelides proboscideus, but relationships within the Elephantulus differed among data sets. Genetic identify values indicated considerable divergence among species. Standard karyotypes showed 2 N = 30 for E. myurus, 2 N = 28 for P. tetradactylus and 2 N = 26 for the other five species. Levels of genetic heterozygosity ranged from 0.0 to 7.4%
