【摘要】 本文研究了高密度饲养条件下,扬子鳄对洞穴的选择特点。结果表明,在高密度饲养下,土壤质地和区域内水位的变化影响扬子鳄对洞穴位置的选择,个体较大的鳄优先选择洞穴点。鳄鱼多选择在含有粘质土壤和黄红壤质土壤区域营建洞穴, 有2条鳄鱼共建一座洞道的行为出现。水位线以下的洞穴洞道中充满着水,鳄鱼能在里面正常越冬。更多还原

【Abstract】 This paper studied the burrowing characteristic of Chinese alligators with high density in captivity. The result showed that the soil quality and water level can affect the selection of burrow sites of Chinese alligators. The bigger individuals can take the advantage of the selection of burrow sites. Chinese alligators mainly select the viscidity soil and yellow-red soil for burrowing. We also found that two alligators could hibernate in the same burrow. Although the burrow channels under water level are always filled with water, Chinese alligators can hibernate normally.更多还原
