Popis: Male and female rats were raised individually in either large boxes filled with soil (burrow environment) or laboratory cages of comparable size (cage environment). In a test of intruder-elicited aggression, intruders exposed to burrow-environment residents lost more body weight, were more likely to have empty stomachs, and received more wounds during a 24 hour aggression test. The results indicate that the physical environment during the period from weaning to maturity is an important determinant of aggression intensity in adult rats.
