Geographic variations of maternally inherited mitochondrial DNA were examined for the Japanese macaque. Sequencing analysis of 412 bp in the D-loop region for 105 samples from 81 localities revealed 43 haplotypes. They were classified into two major groups, eastern and western groups. Their border was located near the border between the Kinki and Chugoku districts. As an exceptional case, the populations from Okutama and Chichibu area in the Kanto district showed distinct types which were close to those in the western group.In general, the distribution of mtDNA variation was restricted to particular geographic range. The type was unusually uniform in the Tohoku district. The number of nucleotide substitutions among the haplotypes was smaller in east than in west, suggesting difference in population history between monkeys in east and west. As geographic range of mtDNA variations is to be changed through the fission of social groups, low degree of mtDNA diversity may indicate recent expansion of ancestral population in eastern part of Japan, probably after the last glacial period. The uniform distribution of mtDNA type in the Tohoku district may result from re-invasion to north succeeding to the postglacial change of climatic and vegetational conditions.

研究了日本猕猴母系遗传线粒体DNA的地理变异。对来自81个地区的105个样本的D-loop区412 bp序列进行分析，发现43种单倍型。他们被分为两个主要群体，东部和西部群体。他们的边界位于近畿区和中国区之间的边界附近。关东地区的Okutama和秩父地区的群体表现出与西部群体相近的独特类型，总体上，mtDNA变异的分布局限于特定的地理范围。这种类型在东北地区异常统一。单倍型之间的核苷酸替换数量东部地区比西部地区少，表明东、西部地区猴的种群历史存在差异。由于mtDNA变异的地理范围将通过社会群体的分裂而改变，mtDNA多样性的低程度可能表明日本东部的祖先人口可能在末次冰期之后最近扩大。东北地区mtDNA型分布的均匀性可能是冰后期气候和植被条件变化后再次向北入侵的结果。
