黄土高原甘肃鼢鼠危害及防治研究 Ⅱ甘肃鼢鼠年龄鉴定及种群年龄结构的研究
- Title:
- Study on Harm and Prevention of Myospalax cansus in Loess Plateau Ⅱ Study on Age ldentification and its Population Structure of Myospalax cansus
- 摘要:
- 1991年4月～1993年6月在宁夏回族自治区西吉县火石寨乡进行了甘肃鼢鼠的生态研究，捕获标本441只（♂163♀278），以胴体重作指标，参考头骨形态变化与量度及繁殖特征，将甘肃鼢鼠划分5今年龄组：Ⅰ. 幼年组，Ⅱ. 亚成年组，Ⅲ. 成年1组，Ⅳ. 成年2组，Ⅴ. 老年组。种群年龄结构的季节特征是：繁殖初期（4月）以Ⅲ组明显占优势，繁殖期（5、6月）以Ⅲ、Ⅳ组为主，繁殖末期（7月）Ⅰ组明显增加，8、9月Ⅱ组比例提高，初冬（10月）以Ⅲ组为主。还探讨了年龄与体重、体长及繁殖的相互关系。
- Abstract:
- The ecological research of Gansu Zoker (Myospalax callous) was carried out in Xiji County,Ningxia Autonomous Region from Apr.1991 to Jun.1993.During the field survey, 441 of samples were captured (163 of male and 278 of female)with sex ratio of 0.59(♂♂:♀♀).Based on the body weight excluding viscera (BWEV) and morphilogical characteristics of skull as well as reproduction,the age distribution was divided into five groups:Group 1 juvenile with BWEV bellow 100g for mele (mean 80.49±2.75g),and bellow 80g for female (mean 66.04±2.66g).Group 2 subadult with BWEV from 101 to 150g (mean 123.17±2.56g)for male; 81-120g (mean 105.34±1.14g) for female.Group 3 adult Ⅰ in which male has the BWEV of 151-220 (average 190.3 1 2.309), and female 121～160g (mean 142.07± 0.969).Group 4 adult Ⅱ male 221-290(mean 248.66±2.459) lfemale 161～200g(mean 176.04±1.20g).Group 5 senior-male BWEV over 290g (maen 312.54±5.18g), female over 200g (213.00±3.85g).The Gausu Zoker population age has the seasonal change which adult Ⅰ group dominated in the beginning of reproduction in April,group of 3 and 4 dominated in reproduction period in May and June,however, the group 1 increased signifitly in the end of reproduction in July, the ratio of group 2 raised from Aug.to sept., and group 3 dominated in late Fall (Oct.).The relations between age and body weight,length of body as well as reproduction were also discussed.
