Social influences on the development of ringtailed lemur feeding ecology

The Socioecology of the Ringtailed Lemur: Thirty-Five Years of Research

Like many cercopithecine monkeys, Lemur catta lives in multi-male female resident groups that usually contain 10 to 20 animals.6–8,10 Sex ratios are approximately 1:17,8,10,11 and sexual dimorphism is slight.12 Females usually remain in their natal group, (but see below) whereas males migrate.13–16 Groups are centered around a core of adult females and their offspring.6 As in Old World monkeys,...

Changes in behavior in free-ranging Lemur catta following release in a natural habitat.

The adjustment of captive-reared and developmentally deprived ringtailed lemurs (Lemur catta) to supported release on St. Catherine's Island, Georgia, was studied over 7 years to examine if these animals developed behavior comparable to wild populations. Initial changes after release included decreased obesity and increased agility as well as foraging for appropriate novel plants. Ranging, dail...

Chemical composition of scent marks in the ringtailed lemur (Lemur catta): glandular differences, seasonal variation, and individual signatures.

The apocrine and sebaceous scent glands of ringtailed lemurs (Lemur catta) appear to serve different social functions. In behavioral experiments, lemurs modulate their responses to scent marks based on the type of odorant, their own physiological state, the signaler's physiological state, and prior social experience. To examine variation in odorant chemistry relative to olfactory behavior, we u...

Temporal Change in Tooth Size Among Ringtailed Lemurs (Lemur catta) at the Beza Mahafaly Special Reserve, Madagascar: Effects of an Environmental Fluctuation

Affiliative relationships between adult males and immature group members in naturally occurring ringtailed lemurs (Lemur catta).

Affiliative relations between adult males and immature group members were studied in three naturally occurring groups of ringtailed lemurs (Lemur catta) over a 12-month period at Beza-Mahafaly Reserve, southwestern Madagascar. No statistically significant difference was found in rates of affiliative interactions between adult males and older immatures (juveniles and adolescents) over reproducti...
