摘要
羽毛是非法猎杀野生动物现场中容易存留的重要证据,兼具较强的稳定性和特异性,可为鸟类的识别鉴定提供佐证。选取黄鹡鸰东北亚种、台湾亚种与阿拉斯加亚种的飞羽、尾羽以及其根部的绒羽作为研究对象,宏观测量飞羽及尾羽内外翈长,同时利用扫描电镜观察3类羽毛的显微结构,对飞羽和尾羽有钩羽小枝的基柄长、羽小钩数、纤毛数、羽小钩数+纤毛数、腹齿数,无钩羽小枝的基柄长、腹齿数;绒羽节直径、节间距、基节长等数据进行测量记录,并利用SPSSAU对记录的数据进行分析比较。结果表明:黄鹡鸰3个亚种飞羽的有钩羽小枝基柄长、无钩羽小枝基柄长,尾羽的纤毛数、腹齿数,绒羽的节间距等显微结构特征均存在显著或极显著差异。
Feathers are important evidence that can easily be left at the scene of illegal wildlife poaching.They possess strong stability and specificity,providing supporting evidence for the identification of bird species.This paper selected the flight feathers,tail feathers,and the down feathers at their bases from three subspecies of the Motacilla flava:the Northeastern Asian subspecies,the Taiwan subspecies,and the Alaskan subspecies,as the subjects.It conducted macroscopic measurements of the inner and outer barb lengths of the flight and tail feathers,and utilized scanning electron microscopy to observe the microstructures of the three types of feathers.Measurements were taken and recorded for the base handle lengths,the number of hooklets,the number of cilia,the number of hooklets+cilia,and the number of ventral teeth in the flight and tail feathers with hooked barbules.For those with proximal barbules,measurements included base handle lengths and number of ventral teeth.Additionally,the diameter of the nodular,distance between nodular,and length of the base nodular of the downy feathers were measured.The recorded data were analyzed and compared using SPSSAU.The results indicate that there are significant or highly significant differences in the microstructural characteristics of the base handle lengths of hooked barbules,base handle lengths of proximal barbules in flight feathers,and number of cilia,number of ventral teeth in tail feathers,as well as distance between nodular for downy feathers among the three subspecies of M.flava.
