Abstract: The population parameters of Mongolian gerbil (Meriones unguiculatus) in Inner Mongolia of China were estimated by using Capture-mark-recapture (CMR) and Jolly - Seber model from June to October in 2000. We found that the possibility of being caught among the individuals in marked population of Mongolian gerbil is not different , that is equal catch-ability ; and the mean probability that an animal kept alive at ith sampling occasion is re-caught at sample i was 89.7 % in each capture-recapture time.It shows that the Jolly-Seber model is suitable for estimating parameters of M. unguiculatus.
Key words: Mongolian gerbil (Meriones unguiculatus), Capture-mark-recapture (CMR), Jolly-Seber model, Equal catch-ability, Probability of recapture
摘要: 以2000 年6 月~10 月群居性长爪沙鼠野生种群的标志重捕资料为依据, 采用Jolly - Seber 模型估算了该鼠种群参数, 结果表明, 长爪沙鼠个体间具等捕性(Leslie 法检验) , 研究期间取样个体的重捕率平均为89.7 %(77.4 % ~ 100 %) ; 参数估计结果具有合理的生物学意义, 认为采用该模型估算长爪沙鼠种群参数是适用的。
