Data are lacking on intraspecific variability in life history traits for the Critically Endangered greater bamboo lemur (Prolemur simus). Until now, detailed investigations on wild individuals had only been published for Ranomafana National Park, limiting the predictive power on the greater bamboo lemurs' possible responses to threats such as habitat loss and climate change. In this study, data were compiled on vital statistics and basic aspects of infant development for a 48-month period in Kianjavato, Madagascar. The area is mixed-use lowland forest with dense pockets of bamboo amid a disturbed landscape. Four core social groups, which would frequently coalesce into two larger groups, were monitored intensively. The birth pulse occurred in mid- to late September, nearly one month earlier than in Ranomafana National Park. Interbirth intervals and rates of attainment of infant developmental landmarks such as locomotor independence and weaning are discussed. Infant mortality averaged 47% with most deaths concentrated in December and January, while adult mortality was low with most deaths occurring during the dry season. Annual female adult mortality ranged from 0% to 22%. The mortality of adult males could not be assessed due to their dispersal.
