Diversity of rodent species was studied in relation to the abundance of grass vegetation, projection cover of arboreal and semi-arboreal vegetation, and mechanical soil composition in the Kyzyl Kum desert (Bukhara Province, Uzbekistan) and in the Chihuahua desert (Bolsón de Mapimí, Durango, Mexico). Species diversity indices for rodent communities in 1-hectare plots significantly varied in both deserts in similar environmental conditions. Nevertheless, the obtained data agree with the data on the hill-shaped relationship between species diversity and productivity of the environment. Stepwise regression analysis of the linear component links suggests that the abundance of grass and the projection cover of arboreal and semi-arboreal perennials, rather than the type of soil surface, exert a significant influence on the diversity of rodent species. At a given projection cover of arboreal and semi-arboreal plants (or an abundance of grass), the diversity of rodent species in Bukhara decreases with an increase in grass abundance (or projection cover of arboreal and semi-arboreal plants). By contrast, in Mapimí the diversity increases. The difference is probably due to both specific environmental conditions and particular fauna genesis.
在克孜勒库姆沙漠（乌兹别克斯坦布哈拉省）和奇瓦瓦沙漠（墨西哥杜兰戈州马皮米盆地），研究了啮齿动物物种多样性与草本植被丰度、乔木和半乔木植被投影覆盖率以及机械土壤成分之间的关系。在两个沙漠中，环境条件相似的1公顷样地中啮齿动物群落的物种多样性指数显著不同。然而，所得数据与物种多样性和环境生产力之间的丘形关系数据一致。线性成分联系的逐步回归分析表明，草本植物的丰度以及乔木和半乔木多年生植物的投影覆盖率，而非土壤表面类型，对啮齿动物物种多样性有显著影响。在给定的乔木和半乔木植物投影覆盖率（或草本植物丰度）下，布哈拉的啮齿动物物种多样性随草本植物丰度（或乔木和半乔木植物投影覆盖率）的增加而降低。相比之下，在马皮米则增加。这种差异可能是由于特定的环境条件和特殊的动物区系起源。
