Abstract

In order to reexamine the taxonomic position of Anderson's red-backed voles in question from the Kii Peninsula, the reproductive compatibility among local vole populations from the Kii Peninsula, Nagano and Fukushima was examined by crossbreeding experiments. Fertility of hybrids was ascertained until F4 in five cross types between Kii Peninsula female and Nagano male voles and to F3 in four cross types of Nagano females with Kii Peninsula males. The resulting F5 and F4 hybrids matured normally (in Line I). Moreover, F1 hybrids resulting from one cross type involving a Kii Peninsula female and a Fukushima male, and in one cross type involving a Fukushima female and a Kii Peninsula males, also, showed healthy growth (in Line II). Thus, the reproductive compatibility between both populations (in Lines I and II) was confirmed. Such reproductive compatibility among these three local populations of the Anderson's red-backed vole strongly supports the belief that all belong to one species, <i>Eothenomys andersoni</i>.<br>
