猕猴(Macaca mulatta)生命表研究

本文研究了猕猴雌性生命表。南湾猕猴各年度全群平均存活率高于93％,特定年龄组逐年存活率直到13岁仍达0.81以上,种群内禀增长率为0.1327,年周增长率为1.1419。用莱斯利矩阵对种群发展作预测,将预测值与1985-1987年的实测值作卡方适应性检验,两者无显著性差异。进一步分析发现该方法预测南湾猕猴种群动态,在7年内是有效的。

A STUDY OF THE LIFE TABLE OF THE RHESUS MONKEY (MACACA MULATTA)

The life table of female rhesus monkey (Macaca mulatta) was studied with the observations of nine years from 1978 to 1987 at Nanwan Peninsula of Hainan Provinre, China in this paper. The average survival rate for all of individuals of a group was higher than 93% in the period of study and the survivol (Ix) of the age-class of 13 years old still was 0.81. The exponential rate of increase of the population was 0.1327 (figure 1 and table 1). The development of the macaque population was forecasted by the method of Leslie Matrix analysis (table 2 and table 3). There was no significant difference between both forecast and actual values from 1985 to 1987 by Chi-square test (figure 2). The result indicated that the forecast value is valid in 7 years for Nanwan monkey population.
