摘要: 在内蒙古典型草原区多种不同植被条件栖息地中分析布氏田鼠当年雄鼠的体重生长差异。研究表明,布氏田鼠在不同植被条件下的体重生长具有显著的差异。在植被条件中等的草场,布氏田鼠的体重生长最佳,在植被条件优越的轻牧草场或者过度放牧草场,布氏田鼠体重生长一般,植被条件较差的重度放牧草场,布氏田鼠的平均体重较低。在不同类型草场,布氏田鼠可以通过调节体重大小和生长速度来适应各种不同类型的草场。

Abstract: The sizes of body mass of Microtus brandti were analyzed in several different grazing habitations.Significant differences have been detected for the body mass of M.brandti in various habitations using ANOVA. M.brandti obtained the biggost mass in the lightly-grazed habitation and get the middle mass in the lightly-grazed and over-grazed habitations.Those living in the seriously-grazed habitation can only reach the lowest body mass.This may be considered an adaptation for the Microtus brandti to the environment.
