Eulmur fulvus，一个由六个亚种组成的复合体，是通过进化分类学赋予物种地位的经典例子。我们使用系统发育物种概念作为生物物种概念的替代方法，以确定不同物种之间基因流的历史模式。fulvussubspecies和赋予物种地位。本文利用种群聚集度分析确定了合理的物种划分，并利用分支系统学分析重建了黄尾桉复合体中不同种群的进化关系。我们测序了三个mtDNA基因区域（d-环，12 S和cyt-b）和一个核区域，酪蛋白激酶，共1247个碱基。通过种群聚集性分析，确定E. fulvuscomplex应分为三个单元;一个单元由六个诊断位点支持。F. albocollaris，一个由三个诊断位点支持的单位。F. collaris，一个单位由两个诊断位点支持，包括其他四个亚种。虽然E. fulvuscomplex有一个共同的祖先，我们在分支分析中发现E. F. CollarisandE. F.白颈菌有一个共同的祖先，这个祖先是最近从其他四个白颈菌的共同祖先中分离出来的。黄貂亚种
Eulmur fulvus, a complex comprising six subspecies, is a classic example of species status conferred through evolutionary taxonomy. We used the phylogenetic species concept as an alternative method to the biological species concept for determining historic patterns of gene flow between the variousE. fulvussubspecies and for conferring species status. In this paper, we used population aggregation analysis to determine the proper species partitions and cladistic analysis to reconstruct the evolutionary relationships of the different populations in theEulemur fulvuscomplex. We sequenced three mtDNA gene regions (d-loop, 12S, and cyt-b) and one nuclear region, casein kinase, for a total of 1247 bases. Through population aggregation analysis, we determined that theE. fulvuscomplex should be split into three units; one unit supported by six diagnostic sites comprisingE. f. albocollaris, one unit supported by three diagnostic sites comprisingE. f. collaris, and one unit supported by two diagnostic sites comprising the four other subspecies. Although all six subspecies in theE. fulvuscomplex share a common ancestor, we found in our cladistic analysis thatE. f. collarisandE. f. albocollarisshare a common ancestor that more recently split off from the common ancestor of the four otherE. fulvussubspecies.
