蜥蜴在受到捕食者的袭击时,会自断其尾,然后逃之夭夭。但蜥蜴一旦失去尾巴,它在蜥蜴群中的地位就会下降,这实际上就会威胁它日后的生存。美国俄克拉荷马州立大学的斯坦利·福克斯和玛格丽特·罗斯克通过模仿捕食者咬伤蜥蜴的方式,使其自然断尾。然后,他们仔细研究了蜥蜴失尾对其在群体中的地位所产生的影响。为了确定各个蜥蜴在群体中所处的地位,他们在实验室里先让一些尾巴完整的 When the lizard attacked by a predator, it would cut off its tail and then fled. However, once a lizard loses its tail, its position in the lizard population will decline, which in fact threatens its future survival. Stanley Fox and Margaret Roskak of Oklahoma State University in the United States naturally tail their way by imitating how predators bite lizards. Then, they carefully examined the impact of the missing lizard lizard on its status in the community. In order to determine the status of each lizard in the community, they first let the tail in the laboratory complete
