摘要我们分析了翡翠斑羚(Aulacorhynchus Prasinus)的遗传变异，这是一种物种复合体，主要分布在墨西哥南部和东部的山地森林中，向南延伸到玻利维亚。对3个线粒体DNA基因(细胞色素b、ND2和ND3)的片段进行了测序，共1,159个碱基对。利用最大简约度、最大似然率和贝叶斯分析，我们发现了一组七个不同的种群，它们对应于整个新热带高地的明显地理突变。这些遗传上截然不同的种群也符合之前对形态数据的分析中发现的地理突变。分子证据表明，中美洲的四个支系和南美的三个支系存在物种待遇。Prasinus Aulacorhynchus Prasinus
Abstract We analyzed genetic variation in the Emerald Toucanet (Aulacorhynchus prasinus), a species complex that ranges primarily along the montane forests of southern and eastern Mexico south to Bolivia. Segments of three mitochondrial DNA genes (cytochrome b, ND2, and ND3) were sequenced for a total of 1,159 base pairs. Using maximum parsimony, maximum likelihood, and Bayesian analysis, we found a set of seven differentiated populations that correspond to clear geographic breaks throughout the highlands of the Neotropics. These genetically distinct populations also correspond with the geographic breaks found in previous analyses of morphological data. Molecular evidence suggests species treatment for four of the Central American clades and three South American clades. Especiación en el Complejo de Aulacorhynchus prasinus
