中文摘要	测量了73只成体荒漠麻蜥的头体长、尾长、头长、头宽、头高、最大腹宽、腹长、前肢长和后肢长9个形态特征,并对荒漠麻蜥环体中段鳞、第9-10环尾鳞、股孔及股孔相隔鳞片的数量进行计数。结果表明荒漠麻蜥雌性与雄性的头体长、环体中段鳞数、股孔数及股孔相隔鳞片数无显著差异,尾长、头部大小、最大腹宽、腹长、前肢长、后肢长及第9-10环尾鳞数均存在两性异形现象。其中,雄性在头长、头宽、头高、尾长及第9-10环尾鳞数方面大于雌性,而雌性在最大腹宽、腹长、前肢长和后肢长方面大于雄性。尾长、头长、头宽、头高、最大腹宽、腹长、前肢长和后肢长均与头体长呈显著正相关关系。研究表明,荒漠麻蜥存在两性异形现象且在个体发育的过程中,雌雄个体的尾长、头长、头宽、头高、最大腹宽、腹长、前肢长和后肢长均表现出不同程度的异速生长。
英文摘要	Nine morphological characteristics of 73 adult E. przewalskii were measured,which included body length,tail length,head length,head width,head height,abdomen width,abdomen length,fore limb length and hind limb length. The number of scales around the mid-body,the number of scales around 9-l0th tail ring,the number of femoral pores and the number of scales between femoral pores were counted. The results show there are no significant difference of body length,the number of scales around the mid-body,the number of femoral pores and the number of scales between femoral pores between males and females,but there are some differences on the size of tail and head,abdomen width and the length of limbs and abdomen,the number of scales around 9-l0th tail ring,which is called sexual dimorphism. Among them,the males have bigger head length,head width,head height,tail length and the number of scales around 9-l0th tail ring,while the females have longer abdomen width,abdomen length,fore limb length and hind limb leg. There are extremely significant positive correlations between body length and eight morphological indicators,including tail length,head length,head width,head height,abdomen width,abdomen length,fore limb length and hind limb length. The results show that there exists sexual dimorphism in E. przewalskii and there are some different degrees of allometric growth between males and females in tail length,head length,head width,head height,abdomen width,abdomen length,fore limb length and hind limb length in the process of ontogeny.
