The paper identifies eight distinct dam-daughter relationship types in rhesus macaques based on grooming, spatial closeness, and agonistic support behaviors, showing demographic factors influence these behaviors differently.

Across 105 rhesus macaque matrilines at two primate centers, family grooming cohesion drops below a mean kinship threshold of 0.16, while lower kinship continuously increases severe within-family aggression.

This study examines how socio-ecological factors influence participation in intergroup competition among urban-dwelling rhesus macaques, finding that affiliative connections and social position significantly affect engagement.
