| Allozyme Varability in Medium-Sized and Large Mammals: Determinants, Estimators, and Significance for Conservation | |
| 1996 Biodiversity letters (3): 81-91 | |
Based on enzyme electrophoretic data, genetic diversity of various medium-sized and large mammalian species is presented. Following various hypotheses under discussion, body size (small v. large), feeding type (herbivorous v carnivorous), mating system (polygynous v. panmictic), and geographic distribution (population structure influenced v. not influenced by Pleistocene glaciations) of species were tested as to their influence on differences in allozyme variation among species. Expected average heterozygosity (H) did not differ significantly among the categories of taxa established according to the above criteria, whereas the proportion of polymorphic loci (P) and the H:P-rate did in most of the comparisons. The same was found in comparisons of undisturbed with bottlenecked populations of various species, whereby only in part of the above categories comprising undisturbed populations genetic variation was higher than in bottlenecked populations. Compared to P and the H:P-rate, H is regarded as less a sensible indicator of genetic erosion. The implications of natural differences in genetic diversity among populations and species for conservation are discussed. |
