The genetic diversities and population structures of Meriones meridianus representing 4 populations in the Qaidam Basin were investigated by examining mitochondrial Cyt b sequences. The results showed that Lenghu-Suganhu population had the highest genetic diversity( Hd = 1. 000; π = 0. 005 30), while the Geermu population had the lowest( Hd =0. 750; π = 0. 002 55). AMOVA analyses indicated that 38. 32% of the total genetic variation was attributable to differences among populations and 61. 68% to difference...

柴达木盆地位于青藏高原北部,其北部为祁连山脉,南部为昆仑山脉,西北部为阿尔金山脉,东部为日月山,是一个封闭的内陆盆地,也是青藏高原内部最大的沉积盆地(Wu et al.,2014a)。柴达木盆地在侏罗纪早期的原生代至古生代地层上开始发育(Chen et al.,2005;Wu et al.,2011),到渐新世
