| 摘 要： | 根据2010年3月—11月在千岛湖地区2个岛屿上社鼠(Niviventer confucianus)的标志重捕数据,分别用Jolly-Seber法、修正Lincoln指数法、Schnabel法和MNA法计算两个岛屿上社鼠种群数量,并深入探讨在陆桥岛屿环境下估算社鼠种群数量的适用方法。研究结果显示,在满足Jolly-Seber法的条件下,通过该方法计算的结果与修正Lincoln指数法无显著差异。但在野外实验中,并不是所有的重捕数据都满足Jolly-Seber法的条件,而且该方法不能估算头尾两月的数量。因此,修正Lincoln指数法更适于估算陆桥岛屿环境下社鼠的种群数量。可为今后开展陆桥岛屿环境下鼠类种群生态学研究奠定基础。

| Abstract: | We live-trapped two Niviventer confucianus populations from March to November of 2010 in Thousand Island Lake region using the capture-mark-recapture (CMR) method. We used Jolly-Seber method, modified Lincoln index method, Schnabel method and minimum number of animals alive (MNA) method to estimate population sizes of Niviventer confucianus, and discussed the applicability of these estimators in white-bellied rats on land-bridge island. Our results showed that there was no significant difference between Jolly-Seber method and modified Lincoln index method. We considered that modified Lincoln index method was more suitable for estimating the population quantity of Niviventer confucianus in the land-bridge island. The study can provide basic data for the future study of population ecology of rodent in the land-bridge island. |
