Evidence of a contact zone between two Rhabdomys dilectus (Rodentia: Muridae) mitotypes in Gauteng province, South Africa

摘要: Recent studies have described the presence of several mitochondrial lineages within Rhabdomys, which was previously considered to be a monotypic genus. The exact distributional limits species and subspecies their contact zones are unclear. In this study we demonstrate that two monophyletic Rhabdomys dilectus present at northern Gauteng province sampling sites in South Africa. Cytochrome b gene sequences, 896 nucleotides length, generated for 36 samples identified 10 unique haplotypes corresponding eight R. (from 32 individuals) d. chakae four individuals). provides first empirical evidence zone conspecific contributes refinement maps southern
