半自然状态下鳄蜥活动时间分配的初步研究

Observation on Time Budget of Shinisaurus crocodilurus in Captivity

在半自然的条件下采用瞬时扫描法对鳄蜥活动时间分配进行了初步的研究,结果表明:在池养鳄蜥的活动时间分配中,静栖占69·09%,在穴占28·82%,移动占0·80%,捕食占0·28%,晒太阳占0·44%,其它占0·58%;比较了不同性别鳄蜥的活动时间分配,其中雄性鳄蜥用在移动的时间占1·15±1·22%,雌性为0·45±1·00%,经过单因素检验显示其差异显著(P<0·01),其它行为活动时间分配差异不显著;初步比较了不同生境中鳄蜥的行为差异,结果显示鳄蜥在池养的条件下弹性行为的表现频次正在下降。

From July to August 2005, the time budget of six types of behavior of Shinisaurus crocodilurus under semi-natural condition in Guangxi Dayaoshan Nature Reserve was studied. The results were as follows： resting 69.09% ; in-nest 28.82 % ; moving 0.80 % ; food foraging 0.28 % ; sun bathing 0.44 % ; others 0.58 %. The comparison of time budget between female and male was made. It indicated that there were no significant differences between sexes except moving behavior. The ratio of Shinisaurus crocodilurus behavioral elasticity was reduced when they were living in captivity comparing to field.
