对已识别个体的长期深入研究使我们能够重新审视狐猴卡塔的社会结构和组织。环尾狐猴的活动范围高度重叠，其大小根据季节和栖息地而变化，不应被视为严格的领地性。该物种生活在雌性居民、多雄性群体中，以一只占主导地位的雌性为中心，而雌性似乎是其他群体成员的焦点。群体平均约有 13 人（范围：5-27 人），成人性别比例基本相等。成年后，所有雄性都会从其出生群体中迁出，年长的雄性平均每 3-5 年就会在群体之间转移一次，尽管有些雄性在同一群体中至少保留了 6 年。群体中的男性可以根据性格、社会地位以及与女性的关系来区分。在深入研究的群体中，已经确定了一个非出生的“中心”男性。这些雄性与雌性互动的频率更高，并且是第一个交配的。雌性表现出择偶行为，拒绝亲缘关系密切的雄性，并积极与非群体雄性交配，这导致了许多雄性交配策略。
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 strictly territorial. This species lives in female resident, multimale groups centered around one dominant female who appears to be the focal point of other group members. Groups average around 13 individuals (range: 5-27) with generally equal adult sex ratios. Upon reaching adulthood, all males emigrate from their natal group and older males transfer between groups at an average of every 3-5 years, though some males have remained in the same ~oup for at least 6 years. Males within a group can be differentiated based on natahty, social status, and relationships with females. In groups intensively studied, a single, non natal "central" male has been identified. Such males interact with females at greater rates, and are the first to mate. Females exhibit mate choice, rejecting closely related males, and actively mating with non-troop males, which results in a number of male mating strategies.
