摘要
2011年2月~2012年7月,对海南鹦哥岭自然保护区内的海南锯腿树蛙(Rhacophorus hainanus)种群分布进行了调查,用野外观察与室内饲养的方法对其繁殖生物学进行了初步研究。结果表明:海南锯腿树蛙分布在鹦哥岭自然保护区内海拔800m以上的溪流边或是季节性水潭附近;该蛙具有明显的性二型特点;繁殖季节为每年的3月至6月,繁殖地为季节性水潭,繁殖包括鸣叫求偶、抱对、产卵三个过程,每次产卵量为126±77枚,蛙卵约7d孵化为蝌蚪,57d蝌蚪变态成为幼蛙。该蛙唇齿式为I:4+4/1+1:II,与云南部分蝌蚪标本以及越南采集的蝌蚪标本有差异。
From February.2011 to July.2012,a survey of the population and distribution of Rhacophorus hainanus was conducted in Hainan Yingeling.and a study on reproductive biology was conducted through field observations and artificial feeding method. The result shows that:Rhacophorus hainanus distributes above the elevation of 1200 meters, and lives in streams or seasonal pool.There are obvious differences between male and females. The breeding season is from March to June. The breeding process includes courtship、hugging、spawning.The quantity of eggs of each spawning is 126±77.The eggs turn into tadpole after 7 days, the transformation finishes in 57 days,and labial tooth row formula is I:4+4/ 1+1:II, which is different from tadpole samples in Yunnan province and Vietnam.
