摘要

山齿鹑(Colinus)由3种与草原相关的新大陆鹌鹑(山齿鹑科)组成:北部山齿鹑(C. virginianus),分布于美国东部至危地马拉;黑喉山齿鹑(C. nigrogularis),分布在Yucatán半岛、尼加拉瓜和洪都拉斯的一些地方;以及冠状山齿鹑(C. cristatus),其活动范围从危地马拉延伸到巴西北部。利用对照区和ND2基因的线粒体DNA (mtDNA)序列对3种山齿鹑的系统发育关系和系统地理进行了研究。我们开发了生态位模型来评估从遗传数据推断出的结论。Colinus由两个非常不同的谱系组成,一个以冠状山齿鹑为代表,另一个以北方和黑喉山齿鹑为代表,两者在遗传上彼此不同。尽管北方山齿鹑具有较高的单倍型多样性,但该物种表现出过去人口统计学和地理扩张的证据,没有系统地理结构,遗传变异与亚种分类之间不一致。生态位模型与最近在墨西哥和美国南部晚更新世避难所北部山齿鹑的活动范围扩展相一致。来自Yucatán半岛的黑喉山齿鹑与尼加拉瓜的不同,作为一个整体,这个物种几乎没有显示出最近扩张的迹象。生态位模型表明,黑喉山齿鹑目前的分散分布已经存在了13万年。虽然冠状山齿鹑没有显示出种群扩张的证据,但mtDNA数据显示了3-4个地理和遗传上不同的谱系。生态位模拟结果表明,在末次盛冰期,冠状山齿鹑在中南美洲的分布范围要广得多。考虑到这三种山齿鹑对气候周期的敏感性,管理者在制定保护计划时除了考虑栖息地的丧失外,还应该考虑气候变化的影响。©2015野生动物协会。

Phylogeography of the bobwhite (Colinus) quails

The bobwhites (Colinus) consist of 3 grassland-associated, allopatric species of New World quails (family Odontophoridae): the northern bobwhite (C. virginianus), distributed from the eastern United States to Guatemala; the black-throated bobwhite (C. nigrogularis), which occurs in scattered localities in the Yucatán Peninsula, Nicaragua, and Honduras; and the crested bobwhite (C. cristatus), whose range stretches from Guatemala to northern Brazil. We used mitochondrial DNA (mtDNA) sequences from both the control region and the ND2 gene to study the phylogenetic relationships and phylogeography of the 3 bobwhite species. We developed ecological niche models to evaluate conclusions inferred from genetic data. Colinus was composed of 2 deeply divergent lineages, 1 represented by the crested bobwhite and the other by northern and black-throated bobwhites, both of which were genetically distinct from each other. Although the northern bobwhite had high haplotype diversity, this species exhibited evidence of past demographic and geographic expansion, no phylogeographic structure, and no congruence between genetic variation and subspecies taxonomy. Ecological niche modeling was congruent with a recent range expansion for the northern bobwhite from Late Pleistocene refugia in México and the southern United States. The black-throated bobwhites from the Yucatán Peninsula were distinct from those in Nicaragua, and as a whole this species displayed little evidence of recent expansion. Ecological niche modeling suggested that the current, fragmented distribution of the black-throated bobwhite has existed for the past 130,000 years. Although the crested bobwhite displayed little evidence of population expansion, the mtDNA data revealed 3–4 geographically and genetically distinct lineages. Results of niche modeling suggest that the crested bobwhite had a much wider distribution in Central and South America during the Last Glacial Maximum. Given the sensitivity of all 3 bobwhite species to climatic cycles, managers should consider impacts of climate change in addition to the loss of habitat when crafting conservation plans. © 2015 The Wildlife Society.
