We analized factors of geographic size variations and molecular evolution of Japanese moles, genus Mogera, Consisting of 260 specimens from 27 localities in Honshu and Shikoku in M.minor, 280 specimens from 23 localities in Honshu, Shikoku and Kyushu in M.wogura, and 41 specimens from Honshu and Sado Island in M.tokudae. As the habitat factors for the size variations, the size of habitat area (indicated by the area of paddy field), soil hardness, five meteorological data taken by nearby meteorological stations were employed for regression analysis. Geographic size variations of moles showed positive correlation with the size of habitat area, but the relation with temperature and precipitation was different according to the species of moles : The size of M.wogura varied negatively with mean minimum temperature and that of M.minor had a positive correlation with yearly mean temperature. Soil hardness (soft soil depth) did not have any significant correlation with the size of mole.The nucleotide sequences of the cytochrome c oxidase subnit I gene and isozyme anaysis of 20 loci well agreed the mole taxonomy presented by Abe (1967) and showed that there are some intraspecific variations in local populations of the moles.

分析了日本鼹鼠(Mogera)的地理大小变异和分子进化的因素，其中包括来自本州和四国27个地点的260号标本，来自本州、四国和九州23个地点的280号标本，以及来自本州和佐渡岛的41号标本。以栖息地面积大小(以稻田面积表示)、土壤硬度为生境因子，对附近气象站采集的5个气象资料进行回归分析。鼹鼠的地理大小变化与栖息地面积大小呈正相关，但与温度和降雨量的关系因种而异，沃氏田鼠的大小与平均最低温度呈负相关，小田鼠的大小与年平均温度呈正相关。土壤硬度(软土深度)与鼹鼠大小无显著相关性。20个基因座的细胞色素C氧化酶亚基I基因的核苷酸序列和同工酶分析与Abe(1967)提出的鼹鼠分类相一致，表明鼹鼠的地方种群存在一定的种内变异。
