Ladies first. That's how it works for the mongoose lemur, as the female occupies the dominant position in the hierarchy. Family groups stay close together when traveling and feeding, but first choice in food and the lead in mating go to her. Females do present a united front with males when defending their territory from other groups through displays of aggression, including vocalizations, charges and scent marking. But there are certain dangers against which even the most ferocious displays offer no defense. Chief among these life-threatening perils are habitat loss, hunting, and capture for the pet trade. Can the lemurs last?
