- Аннотация: The formation of sexual size dimorphism with aging was studied within several generations of a R. arvalis population. Within a generation, the metamorphs with higher growth or development rate reached relatively larger size at first reproduction (that occurred after 3rd or 4th wintering). These differences between metamorphs’ groups were more conspicuous in females than in males. The between generation variation in growth rate was revealed also (both in females and males). In general, the growth rate after maturation was higher in males, resulting in larger (than in females) body length at each age.
