Genetic diversity and demography of Bufo japonicus and B. torrenticola (Amphibia: Anura: Bufonidae) influenced by the Quaternary climate.

ABSTRACT: The Quaternary climate affected the present species richness and geographic distribution patterns of amphibians by limiting their activities during the glacial period. The present study examined the phylogenetic relationships of Japanese toads (Bufo japonicus and B. torrenticola) and the demography of each lineage from the past to the present based on mitochondrial sequences and ecological niche models. Japanese toads are a monophyletic group with two main clades (clades A and B). Clade A represents B. j. formosus, including three clades (clades A1, A2, and A3). Clade B contains three clades, two of which corresponded to B. j. japonicus (clades B1 and B2) and the other to B. torrenticola. Clade B2 and B. torrenticola made a sister group, and, thus,
