摘要

我們以11個微隨體DNA基因座遺傳標誌，探討臺灣短尾鼩（Anourosorex aquamipes）的親屬關係。利用這11個遺傳標誌，我們可以設定辨識身分的「遺傳條碼」給36隻短尾鼩。我們研究三個地理範圍的短尾鼩族群，分別是3公里、15公里和100公里的直徑範圍，估算每個族群內個體間的親屬關係值。族群的平均親屬關係值和直徑範圍大小成反比：即平均親屬關係值隨範圍縮小而漸增。然而即使在小範圍內，個體間親屬關係值的變異並不亞於大範圍的變異，而且在小範圍內亦有親屬關係值不同的亞群存在。

We address the genetic relatedness of the mole shrew, Anourosorex squamipes, in Taiwan, employing 11 microsatellite DNA markers. These markers enable us to assign ”bar codes” to each of the 36 mole shrews studied for individual recognition. We analyzed the relatedness among individuals sampled from populations at 3 levels of geographical scale, i.e., individuals sampled within a radius of 3, 15, and 100 km, respectively. The mean relatedness values were inversely proportional to the geographic realms of the populations: the mean relatedness value increased as the range decreased. However, even within the populations of a small range, variations of relatedness were no less than those of populations of larger ranges. Often local populations contained subgroups in terms of relatedness.
