扬子鳄幼鳄越冬时水分补充方式的探讨

Study on the water complement manners of young Chinese alligator during its hibernation

对扬子鳄在越冬时水分补充方式,有两种意见。一种认为扬子鳄越冬后不再取食任何东西,其洞穴中的积水仅供湿润皮肤之用;另一种意见认为扬子鳄在此时仍能饮水,至少在越冬后期是如此。

This paper deals with the water complement manners of young Chinese alligators duringits hibernation period.40 young alligators are tested in two groups.The experimental groupincludes 15 individuals which are kept wet skin and dry head,with a bath treatment eachweek.The contrastive group consists of 25 individuals which are immersed in 2cm deepwater.With 43 days feeding after hibernation.It is found that:alligators in experimentalgroup are all alive,their body-weight grows faster than that of the contrastive group.Thecontrastive group has 2 alligators died.The effective way for water complement of youngalligators is by skin absorption and not by drinking.
