摘要

我們首次報告臺灣地區十種屬於蝙蝠科的蝙蝠之核型。三種鼠耳蝠（Myotis），即渡賴氏鼠耳蝠（M. formosus watasei）、寬吻鼠耳蝠（M. latriostris）與臺灣鼠耳蝠（M. taiwanensis），都具有典型的鼠耳蝠屬的核型，為2n（雙套）等於44，FN（染色體臂數）為50。臺灣長耳蝠（Plecotus taivanus）的核型為2n = 32, FN = 50、堀川氏棕蝠（Eptesicus serotinus horikawai）為2n = 50, FN = 48、臺灣黃喉蝠（Arielulus torquatus）為2n = 50, FN = 48及臺灣管鼻蝠（Murina puta）為2n = 44, FN = 50皆呈現出同屬異種間所擁有保守的核型。高頭蝠（Scotophilus kuhlii）（2n = 35, FN = 48）和摺翅蝠（Miniopterus schreibersii）（2n = 46, Fn = 50）的核型則與分布其他地區的相同種類所被分析過的核型一樣。臺灣地區屬於山蝠屬（Nyctalus）的物種其核型為2n = 36，與絨山蝠（N. velutinus）相同而不同於歐洲山蝠（N. noctalus）的核型（2n = 42）， 故臺灣本種應屬於絨山蝠（N. velutinus）而非歐洲山蝠（N. noctalus）。

The karyotypes of 10 Taiwanese vespertilionid bats were examined for the 1st time. Three Myotis species (M. formosus watasei, M. latriostris, and M. taiwanensis) have the standard Myotis karyotype of 2n = 44 with FN = 50. The karyotypes of Plecotus taivanus (2n = 32, FN = 50), Eptesicus serotinus horikawai (2n = 50, FN = 48), Arielulus torquatus (2n = 50, FN = 48), and Murina puta (2n = 44, FN = 50) show conservative patterns when compared to other species of the same respective genus. Scotophilus kuhlii (2n = 36, FN = 48) and Miniopterus schreibersii (2n = 46, FN = 50) have karyotypes essentially identical to those previously reported from other regions. Nyctalus sp. from Taiwan has the same karyotype of 2n = 36 as that of N. velutinus from China and should be separated from N. noctula (2n = 42) based on the different karyotypes.
