Abstract

Changes in the skull size of the red fox (Vulpes vulpes L.) along the eastern macroslope of the Ural Range from the forest-tundra to the steppe are analyzed. The sizes varied from minimum in the north to maximum in pre-forest-steppe pine-birch forests. Further south, the size of the skull decreased again. The average fox population density changed similarly. Based on these data, it was concluded that the sizes change in accordance with the optimum rule, and not with Bergman’s rule. Probably, microevolutionary adaptations to living conditions are influenced by general factors that influence both body size and the population density of the species.

乌拉尔经线上的红狐头骨大小变异：伯格曼法则还是最佳法则？

摘要分析了红狐（Vulpes vulpes L.）头骨大小沿乌拉尔山脉东部大斜坡从森林-苔原到草原的变化。红狐头骨的大小从北部的最小到草原前松桦林的最大不等。再往南，头骨的大小再次减小。狐狸的平均种群密度也发生了类似的变化。根据这些数据得出的结论是，狐狸头骨大小的变化符合最优法则，而不符合伯格曼法则。对生活条件的微观进化适应可能受到影响物种体型和种群密度的一般因素的影响。
