摘要：

By examining environmnetal constraints on life history characters among 3 elevationally distinct populations of S. merriami in W Texas, the authors show how environmental gradients in temperature and food abundance interact to constrain body temperatures, daily activity times, growth rates, and age-specific body size. These differences result in opposite responses from males and females with respect to their size and age at first reproduction. -from Authors
