Скачать или смотреть Milne-Edwards' Sifakas in 34 seconds—Low birth rate and rate of achieving maturity

This is the Milne-Edwards' sifaka (Propithecus edwardsi)! Milne-Edwards’s sifaka groups are female-dominated, with females winning the majority of male-female conflicts, although, in general, aggression rates are relatively low in this species. Female dominance is common in lemur species, but rarer among other primates.

Milne-Edwards’s sifakas exhibit an unusually flexible social system compared to many other primates. They might live in harems, multi-male/multi-female groups, male-female pairs, and single-female/multi-male groups. Even more remarkably, the same individuals may engage in different social systems each year. Researchers aren’t yet sure what causes the different social systems to form, although it’s possible that environmental factors, such as food availability, may have an influence. None of the different social systems appear to be more beneficial than the others for infant survival. Regardless of social system, groups tend to contain only a small number of juveniles and infants, often just one or two. Learn more: https://neprimateconservancy.org/miln...
