中文摘要 | 本研究定序出11隻臺北市立動物園黑熊及4隻玉山國家公園野生臺灣黑熊的粒線體DNA細胞色素b(397個鹼基)及控制區域(532個鹼基)序列,其中細胞色素b基因變異性低,僅發現3個有效變異位置,而控制區域具有48個變異位置,具有較高的變異性。分析控制區域序列共發現11種基因型,玉山的4隻野生黑熊與動物園中的B13具有相同的基因型,另外10隻園內黑熊則分別屬於不同的基因型。研究結果可確定B13為本土黑熊,至於所檢測個體間遺傳上的分歧,可能肇因於飼養動物的種源不一,或是臺灣黑熊族群本身便具有較高的遺傳變異性。 |
英文摘要 | Mitochondrial DNA cytochrome b and control region were partially sequenced (397 bases in cytochrome b and 532 bases from control region) from 11 black bears (Selenarctos thibetanus) captive in Taipei Zoo and 4 wild bears from Yushan area. Variation is low in cytochrome b but is high in control region with 3 and 48 variable sites, respectively. From the control region sequences, 11 haplotypes were found. Four wild bears and one zoo bear (B13) share the some haplotype indicating that B13 should be a native individual. Each of the other ten bears has their unique haplotypes. Two explanations, different places of origin and a genetically divergent block bear population in Taiwan, are proposed to account for the genetic divergence detected in this study. |
