于2011年9月在内蒙古库布齐沙漠捕获118条草原沙蜥(Phrynocephalus frontalis)幼体, 测量其部分身体指数并对其两性异形进行研究。结果表明, 雄性幼体和雌性幼体的平均体长分别为36.3mm和34.0mm, 雄性的体长显著大于雌性。两性异形表现为雄性幼体有较大的头部和尾部, 雌性幼体具有较大的腋胯距。草原沙蜥幼体的局部形态特征皆与体长成正相关。
A total of 118 juvenile Toad-headed Lizards (Phrynocephalus frontalis) were collected in September 2011 from Kubuqi desert (40°12′N,111°06′E), Inner Mongolia. We measured snout-vent length, head width, tail length and abdomen length to analyze their sexual dimorphism. by t-test and regression analysis. The male was significant larger than the female in snout-vent length (SVL) (t=3.702, df=116, P<0.001). The mean SVL of males was 36.3mm while the mean SVL of females was 34.0mm. The male had a bigger head (t=4.616, df=116, P=0.002) and longer tail (t=3.958, df=116, P<0.001), while the female had bigger abdomen (t=2.292, df=116, P=0.024). All the morphological traits measured were positively related to SVL.
