由于雌性狐猴的繁殖活动要适应季节性的资源供应情况，因此雌性狐猴承受的压力可能会因产前和产后的高产妇投资以及群体生活而加剧。在这种情况下，雌性的支配地位可以被视为一种关键行为，使雌性能够在高度季节性的环境中与不止一个非出生的雄性共存。雌性可以忍受全年的雄性成员，因为雄性可以提供低成本的哨兵来探测和防御捕食者。此外，雄性成员对雌性和雄性来说都可能是一种可行的繁殖策略，特别是因为雌性首先与群体中的雄性交配。雌性对小雄性的选择，以及对雄性体型的生态和生殖限制，可能导致了目前环尾狐猴中雌性主导的制度。
Stresses imposed on female lemurs by adapting their reproductive events to seasonal resource availability may be exacerbated by high pre- and 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 year-round 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.
