Resource Competition in Wild Populations of Ringtailed Lemurs (lemur Caita ): Implications for Female Dominance Abstract
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 m...
متن کاملAndrogen levels and female social dominance in Lemur catta.
Morphological and behavioural traits which improve agonistic power are subject to intrasexual selection and, at the proximate level, are influenced by circulating androgens. Because intrasexual selection in mammals is more intense among males, they typically dominate females. Female social dominance is therefore unexpected and, indeed, rare. Ring-tailed lemurs (Lemur catta) are sexually monomor...

Lemur social systems have the striking social feature, that adult females consistently evoke submissive behaviour of adult males.

Here we con rm female dominance over males on the basis of a 5-month eld study of the social behaviour of four groups, in the Lake Alaotra marshland of...
متن کاملFemale rule in lemurs is ancestral and hormonally mediated
Female social dominance (FSD) over males is unusual in mammals, yet characterizes most Malagasy lemurs, which represent almost 30% of all primates. Despite its prevalence in this suborder, both the evolutionary trajectory and proximate mechanism of FSD remain unclear. Potentially associated with FSD is a suite of behavioural, physiological and morphological traits in females that implicates (as...
متن کاملFemale social dominance in two Eulemur species with different social organizations.
Female social dominance is rare in mammals, but common in lemurs. We investigated social dominance in two Eulemur species; the polygynous crowned lemur (E. coronatus) and the monogamous red-bellied lemur (E. rubriventer), using four and two social groups, respectively. We collected data on agonistic interactions and two types of affiliative behavior (grooming and maintaining spatial proximity)....
