Abstract

The development stability has been assessed (by the magnitude of the fluctuating asymmetry of craniological traits) with the change in the number of the Korean field mouse Apodemus peninsulae in Mongolia. It has been shown that an increase in the abundance of this species is not accompanied by a violation of developmental stability, but occurs against the background of a high abundance of other species (the gray red-backed vole Clethrionomys rufocanus and the reed vole Microtus fortis). The result obtained testifies to the assumption that not only the population size of the studied species itself, but also the increase in the number of other species of the community can play a role in manifestation of the overcrowding effect, which can lead to a change in the state of individuals recorded in this case by reduce the developmental stability.

蒙古朝鲜田鼠（Apodemus peninsulae）种群动态的发育稳定性评估。

摘要

随着蒙古朝鲜鼠Apodemus peninsulae数量的变化，已经评估了发育稳定性（通过颅骨性状的不对称波动幅度）。已经表明，该物种的丰度增加并不伴随着对发育稳定性的破坏，而是在其他物种的丰度很高的背景下发生的（灰背红田鼠Ruethcanus和芦苇田鼠Microtus fortis）。）。获得的结果证明了这样一个假设，即不仅研究物种本身的种群数量，而且社区其他物种数量的增加都可以在过度拥挤效应的表现中起作用，这可能导致种群的变化。这种情况下记录的个体状态降低了发育稳定性。
