The Intersexual Differences of Sexual Dimorphism,Feeding Habits and Locomotor Performance at Different Temperatures of Southern Grass Lizard(Takydromus sexlineatus) in Zhaoqing,China [PDF]
通过测量头、尾、体和胃检,研究肇庆南草蜥TAkydrOMuS SEXlInEATuS个体发育过程中两性异形和食性差异。南草蜥成体个体两性大小无显著差异,雄性头部显著大于雌性,两性头部大小异形可能是受到性选择压力的结果。雌雄个体食物生态位重叠度较高,两性生态位差异微弱,食性差异与两性头部异形无明显相关性。通过设计13种不同的环境温度,研究体温变化对南草蜥两性个体运动能力表现的影响。结果显示环境温度通过影响体温而影响南草蜥的运动表现,两性个体疾跑速均具有在低体温范围内随体温升高而加快 ...
