Crowding stress and violent injuries among behaviorally inhibited rhesus macaques

A rhesus group of 36 animals was kept during 6 'warm' months in a large outdoor enclosure, during 6 'cold' months confined in a building. During the 6-month period of confinement stress, a fivefold acceleration in [medically-attended] injury incidence was...
