In a population of "Microcebus berthae", males significantly outnumber females. Despite there being no sexual dimorphism in skull length, canine height, or tail length, the average female is larger than the average male in head-body length and head width. Average body mass, while relatively equal during mating season, becomes smaller for males in the duration of time excluding mating season. Males have a home range of about , while females have a home range of about . Females tend to remain in a home range that is close to, or includes their place of birth. This is the opposite of males, who tend to disperse from their place of birth. The home ranges of individual lemurs tend to overlap with each other, with female home ranges overlapping with that of one or two other females, and male home ranges overlapping with that of up to nine other males.
