标记重捕法对模式产地霸王岭睑虎种群资源调查
|
摘要
霸王岭睑虎Goniurosaurus bawanglingensis是海南岛特有种,自2002年被命名以来,因种群数量小、分布区窄、栖息地破碎化等因素被《中国生物多样性红色名录》列为易危(VU)等级,种群资源现状尚不清楚。2018年7—8月,根据霸王岭睑虎种群分布,在模式产地霸王岭国家级自然保护区内选择了2个样区,首次采用植入电子标签的标记重捕法对种群密度、性比、窝卵数、成幼比等开展调查,并比较了雌雄个体的形态特征。结果显示:样区A种群密度为846只/hm~2,性比1.6∶1,成幼比7∶1;样区B种群密度为591只/hm~2,性比1.2∶1,成幼比10∶1。窝卵数为1～3枚,87%的窝卵数为2枚。身体量度特征(除吻长外)在两性间差异无统计学意义。研究结果进一步补充了霸王岭睑虎的基础生态学资料,可为资源状况评估和保护提供依据。此外,本研究证实了植入电子标签是对睑虎属Goniurosaurus物种野外标记研究的一种简单、有效的方法,可对动物进行长期标记。
Goniurosaurus bawanglingensis is endemic to Hainan Island, China. Since its discovery in 2002, small population, limited distribution, and habitat fragmentation make this species listing as vulnerable(VU) under the Redlist of China's Biodiversity. The current population status of G. bawanglingensis still remains unknown. Based on the species distribution, two sample areas of the Bawangling National Nature Reserve were selected to investigate the population density, sex ratio, clutch size, and ratio of adult to juvenile by using a capture-recapture method from July to August 2018. The morphological characteristics of male and female individuals were also compared. The results showed that the population density of G. bawanglingensis in sampling area A was 846 individuals/hm~2, the sex ratio was 1.6∶1, and the ratio of adults to juveniles was 7∶1. The population density in sampling area B was 591 individuals/hm~2, with the sex ratio of 1.2∶1, and the ratio of adults to juveniles was 10∶1. The clutch size ranged from 1-3 and was 2 for 87% of the individuals. The morphological characteristics(except for snout length) had no significant difference between sexes. These results further complement the basic ecological data and provide a basis for the status assessment and protection of G. bawanglingensis. This study also suggests that the capture-recapture method using electronic tags is a simple and effective method for field survey of Goniurosaurus species, and thus can facilitate long-term monitoring.
