摘要
2018年7—9月,在大桂山鳄蜥自然保护区的鱼散冲、吃水冲和打柴冲,通过测量野外鳄蜥的栖枝高度,利用相关性分析、逐步回归分析及广义线性混合效应模型分析,发现鳄蜥的栖枝高度与鳄蜥的身体形态呈显著正相关关系,成体不同性别的栖枝高度差异不显著,鳄蜥个体越大会倾向于选择更高的栖枝。这可能与较大个体鳄蜥所需的食物量、捕食范围、光照、躲避天敌的能力以及种内领地竞争能力有密切相关。另外,不同溪沟、不同月份的鳄蜥栖枝高度也有所不同,这可能跟所处生境的地势地貌、植被类型以及水文条件等有一定关系。
Habitat height is important for animal to utilize their environment.From July to september 2018,the perch height of crocodile lizard(Shinisaurus crocodilurus)was study by measuring branches in Yusan gully,Chishui gully in Dachai gully in Daguishan Nature Reserve,China.It was found that the large-bodied lizards tend to choose higher perch height,due to the reason that bigger one may needs more food,larger hunting area,more illumination and the ability to avoid enemies or manor competition.In addition,the perch height may be different in different gullies and different months due to different topography,vegetation type and hydrological condition.
