Christine Drea: Demystifying female dominance in lemurs and meerkats (16 Sept. 2025)

Title: Demystifying female dominancei n lemurs and meerkats Presenter: Christine Drea Institution: Duke University, USA Exceptional species serve as ‘experiments of nature’ for understanding the function, development, evolution, and mechanisms of sociality. Building on data from the iconic spotted hyena (Crocuta) and ring-tailed lemur (Lemur) - female-dominant mammals from monotypic genera - I present comparative studies of behavioral endocrinology, intraspecific communication, and neuroanatomy in the diverse Eulemur clade and experimental field studies of the notoriously aggressive meerkat (Suricata). Results reveal new, ecologically malleable patterns of neuroendocrine control over behavior, call into question implications of universality based on model systems, show sexual selection and life-history trade-offs operating in females, and illustrate unique contributions from nontraditional species.
