Resource Competition in Wild Populations of Ringtailed Lemurs (lemur Caita ): Implications for Female Dominance Abstract
نویسنده
چکیده
Michelle L. Sauther Department of Anthropology Washington University St. Louis, MO 63130 U.S.A. Stresses imposed on female lemurs by adapting their reproductive events to seasonal resource availability may be exacerbated by high preand post-natal maternal investment and by group living. Within such a context female dominance can be seen as a critical behavior, enabling females to coexist with more than one non-natal male within a highly seasonal environment. Females may tolerate yearround male membership as males provide low-cost sentinels for predator detection and defense. Furthermore, male membership may be a viable reproductive tactic for both females and males, especially because females mate first with group males. A combination of female choice of small males and ecological and reproductive constraints on male size may have led to the current system of female dominance in ringtailed lemurs.

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...

Michelle L. Sauther and Robert W. Sussman Department of Anthropology Washington University St. Louis, MO 63130 U.S.A. Long-term and intensive studies of identified individuals have enabled us to reexamine the social structure and organization of Lemur catta. Ringtailed lemurs have highly overlapping home ranges which vary in size de~endin~ upon season and habitat, and should not be considered s...
متن کاملReproductive Behavior of Free-Ranging Lemur catta at Beza Mahafaly Special Reserve, Madagascar
Observations of reproductive behavior in free-ranging Lemur catta were carried out during one annual cycle. Variability in the behavior of female ringtailed lemurs during parturition appears to be mainly a function of the female's parity and thus her experience. Females within a troop show estrous asynchrony and characteristically mate with more than one male. Females also exhibit proceptive be...
متن کاملChemical 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...
