应用扫描电镜对白鼬(Mustela erminea)和黄鼬(M. sibirica)背部和腹部直针毛的鳞片花纹类型进行了 研究。结果表明,白鼬和黄鼬同一部位直针毛鳞片花纹的排列顺序、主要鳞片类型、鳞片高度、密度以及同种类型鳞片的外部 形态均存在一定差异,即种间均存在差异,而在种内则表现出较高的相似性和一致性。白鼬背毛和腹毛主要鳞片类型均为长瓣 型,杂波型次之; 黄鼬背毛和腹毛的主要鳞片类型均为杂波型,长瓣型次之。背毛和腹毛杂波型鳞片的密度在2种动物间差异均 极显著(p<0.01),背毛长瓣型鳞片的密度和高度在2种动物间差异均显著(p<0.05)。据此,笔者分析了利 用鼬科动物毛鳞片花纹进行物种鉴定的可行性及需要注意的问题。
Abstract
We analyzed the morphology of guard hairs sampled from the back and abdomen of the white weasel (Mustela erminea)and siberian weasel (M. sibirica) by using the scanning electron microscope technique. Statistics analysis indicated significant differences were found between the two species in morphological parameters such as the order of scale types along the hair, dominant scale types, scale height, density and shapes. The results showed that the order of dominant scale type of guard hairs from both the back and the abdomen of the white weasel was the elongated petal followed by irregular wave, while the dominance of scale types in the siberian weasel was irregular wave followed by elongated petal. The differences of density of the back and abdomen irregular wave were very significant(p<0.01)between the two species, while the density and the height of the back elongated petal were significant different between the two species. Some noteworthy questions for such application were also discussed based on this study.
