摘 要
台灣長鬃山羊(Capricornis swinhoei)為台灣特有的保育類野生動物，本研究的目的乃藉由分子生物學以及形態學的特徵，探討台灣長鬃山羊族群內的遺傳歧異度、觀測族群之架構、分化情形以及生物地理親緣關係。採樣包括本島各縣市之山地及其主要山脈的野生長鬃山羊族群樣本，使用粒線體DNA的控制區序列作為比較的依據，因其具有不受有性生殖再重組的影響，以及演化速度快的優點，可解答種內地理親緣關係的問題，以此片段利用GCG巨分子分析軟體排序及分析，並以MEGA分析軟體計算其遺傳距離進行鄰接法(neighbor-join) 、最大簡約法(maximum parsimony)支序分析建構其親緣關係樹，研究的結果將台灣長鬃山羊分為南北兩群，而頭骨形態測量分析亦支持這樣的結果，配合地理分佈、生態習性與巨觀的地質資料，建立起台灣長鬃山羊的族群以及親緣關係的資訊，將可提供保育工作之參考。

Abstracts
Capricornis swinhoei is one of the indangered wild animals in Taiwan. The objective of this study is using molecular biology and morphology methods to analyze the genetic diversity, observed population structure, differentiation and biogeographic relationships among the population of Capricornis swinhoei. Samples used in this study were collected from the Central Mountains located in Taiwan. DNA sequences (1099 bp) from the mitochondrial DNA (mtDNA) control region, D-loop, were used to test the phylogeographic relationships among the Capricornis swinhoei. A phylogenetic tree was constructed on the basis of GCG-Seq Web and MEGA softwares. In addition, distance analyses, neighbor-join, and maximum parsimony to resolve these phylogenetic relationships were performed. The C. sumatraensis and C. crispus sequence were also determined and used as the outgroups. Our findings clearly demonstrate that Capricornis swinhoei can be clustered into two groups, north and south groups, and consistent with the truth of geographic isolation. The data obtained from this study may facilitate the program of wildlife conservation in Taiwan.
