黑颈鹤与灰鹤羽毛形态结构特征初步分析

Preliminary Analysis of Morphological Structure of Feather from Grus nigricollis and Grus grus

  • 摘要: 采用显微成像术及形态计量分析技术对黑颈鹤与灰鹤的初级飞羽、次级飞羽、尾羽及绒羽的结构进行了形态学分析,应用单因素分析、独立样本t检验对形态结构量化指标进行了统计分析,并建立了特征指标的Fisher判别函数。结果显示:宏观结构层面,2种鹤类羽毛的色泽形状不同,且初级飞羽、次级飞羽内翈羽枝长,尾羽内翈羽枝与羽干的夹角,初级飞羽羽片面积差异显著;微观结构层面,2种鹤类的次级飞羽有钩羽小枝腹齿数及纤毛对数及羽小钩数,飞羽的无钩羽小枝腹齿数,尾羽的有钩羽小枝羽小钩数,绒羽节状羽小枝的节直径以及节间距等结构指标差异显著。通过对黑颈鹤与灰鹤的羽毛宏观、微观的特征结构进行量化分析,构建了以差异指标为依据的Fisher判别函数,使用回代法检验判别方程的正确率为80.2%。综上所述,通过有钩羽小枝羽小钩数、成对纤毛数、腹齿数,无钩羽小枝腹齿数,内翈羽枝与羽干夹角,内翈羽枝长,羽片面积和羽片羽轴长这8个量化指标,可以对未知来源的灰鹤与黑颈鹤的初级飞羽、次级飞羽、尾羽样本完成种间分类,进一步丰富了我国珍稀鹤类物种鉴定方法或途径。

     

    Abstract: The primary flight feathers, secondary flight feathers, tail feathers and down feathers of Grus nigricollis and Grus grus were microscopically imaged, and the morphological data were determined and compared by statistical analysis. The quantitative indexes of morphological structure were statistically analyzed by single factor analysis and sample t test, and the Fisher discriminant function of characteristic indexes was established. The results were showed as following: the length of the barb in the inner web of remiges feathers, the angle between the barb in the inner web of tail feathers and the area of the accessory pinna of a primary flight feather, are remarkably different between G. nigricollis and G. grus in the terms of macrostructure; the number of cilia couples and ventral teeth from distal barbules in secondary flight feathers, the number of ventral teeth in proximal barbules of remiges feathers, the number of hamuli from distal barbules in tail feathers, the distance between nodular and diameters of nodular between the 2 kinds of Grus in the terms of microstructure also showed significantly different; macroscopic and microscopic characteristics of the Grus feathers were quantitatively analyzed, and Fisher discriminant function based on the difference index was constructed. The accuracy rate of using back substitution method to test the discriminant equation is 80.2%. It suggested that Grus of primary and secondary flight feathers and tail feathers of sample classification can be achieved by the number of hamuli, cilia couples, ventral teeth from distal barbules, the number of ventral teeth in proximal barbules, the angle between the barb in the inner web, the length of the barb in the inner web of remiges feathers, the area of the accessory pinna and Length of a feather shaft. It further enriches the identification methods or approaches of rare crane species in China.
