The Difference Of The Winter Morphological Characters Of Fur Of Mustela Sibirica Manchurica Brass Between Tonghe And Jiaohe

Animal's appearance characters are the result of adapting to physiological progress.Adaptation is a phenomena that biology adapt to the different environment characters throughcompetition, is the result of natural selection. Mammalian hair is the medium they contact withthe outside environment, is a complex evolution and adaptation system, it contains body'sinterior activity information; also represent the relationship between body and environment.The 40 sampled Mustela sibirica manchurica Brass are selected from Tonghe in HeiLongjiang province and Jiaohe in Ji Lin province, winter weasels respectively 20. They areselected from November to December in 2005 and 2006. Microscopically morphologicalcharacters such as hair color of mid back, hair diameter, hair density, medulla diameter,absent medulla proportion of top and bottom of hair, and proportion of each scale type of hairand macroscopically morphological characters such as the area, length and thickness of fur aremeasured.SPSS statistic software is applied to analyze these collected data. Then, through carryingout correlation analysis, we know that:1. Through the experiment we can conclude the color of mid back pin hair in Tonghe andJiaohe is the same, it's DarkKhaki.2. There are distinctly gender differences between male and female Siberia weasel, thecharacters of fur between male and female are distinctly different.3. The male of Mustela sibirica manchurica Brass in Tonghe and Jiaohe are distinctlydifferent in the fuzz length of mid-back, the fuzz thin of hip, the fuzz medulla diameter proportionof mid-back and hip, other parts except tail straight pin hair similar flat squama, other measuresare not distinctly different.4. The otherness of female is same with male.
