Assessing the effects of social environment on blood pressure and heart rates of baboons

In the social companion condition, a subject was able to have visual, tactile, and auditory interactions with his companion through the wire mesh walls of the specially designed cages. When animals were housed with social companions their blood pressures were...

Is social housing of primates always the optimal choice? In: Through the Looking Glass

Objective criteria of enrichment

39 cotton-top tamarins living in four families were observed following stimulating husbandry procedures [capture, birds passing overhead]. Arousal led to an improvement in behaviour (i.e., decrease in activity and an increase in affiliation) during the remainder of the day.

Effects of woodchips and buried food on behavior patterns and psychological well-being of captive rhesus monkeys

The addition of woodchips increased exploration and feeding levels and decreased social interactions among group-housed animals. Burial of regular monkey chow in woodchips had little effect on behavior beyond that of the woodchips alone, increasing exploration and decreasing passivity. The...
