Social dominance hierarchies and foraging priority in rhesus macaques
Quick fact
In rhesus macaque troops, high-ranking females typically have priority of access to food, water, and safe resting spots, and they often displace lower-ranking individuals from these resources—a pattern that holds even when food is plentiful.
Why this is interesting
In a troop of rhesus macaques, every individual knows its place. But why does that place so directly determine who eats first, who eats best, and who goes hungry?
