摘要
白鹇Lophura nycthemera是广布于我国南方和中南半岛的鸡形目鸟类,目前共记录有15个亚种。由于受河流、不适宜栖息地等环境的阻隔,白鹇现代分布区呈现部分连续、间断分布的地理格局,且成年雄鸟的上体羽色在亚种间具有明显变化,呈现复杂的羽色多态性。本文通过测量15个亚种的262号标本,从羽色和量度特征上对各个亚种进行了分组和比较。发现部分邻域分布的亚种在羽色和量度特征上相近或重叠,不具有稳定的可区分的外形特征,难以达到亚种的分类标准。进而指出了目前依赖于模式概念建立的种下分类系统存在的缺陷,提出了需要结合分子系统地理学方法从进化历史角度厘定白鹇种下分类的必要性。同时,对白鹇的起源与扩散、羽色演化和保护生物学等研究方向进行了展望。
Silver pheasant Lophura nycthemera is wide spread in south China and Indochina with totally 15 subspecies. The plumage colors in upper body of the adult males were polymorphic among the subspecies. The geological isolation (i.e. rivers,strait and unsuitable habits) shaped its partial continuous and holistic separate pattern of distribution on intraspecific level. According to our widely examination of specimens (262 specimen from all of 15 subspecies) on the plumage color and measurements,with literature review on the nomination history and geographical distribution of all subspecies,we grouped the subspecies into dark morph group and pale morph group. Moreover,we discovered that some assumed subspecies do not deserve the status of subspecies due to the overlap of morphological traits and absence of unambiguous geological limits. Further,we pointed out the necessity of phylogeographic study to clarify the intraspecies taxonomy and evolution of plumage color of this pheasant.
