     Previous research demonstrates that relocation can have lasting behavioral effects. In the study reported here we assessed behavioral activity in middle-aged male rhesus macaques prior to, and following, relocation and change of housing condition. Twelve 16 year old monkeys were moved from pen housing to indoor cage housing. As infants, six monkeys were mother-reared and six were nursery-reared. Activity data was collected with a wristwatch actimeter within a collar worn by each monkey. We hypothesized that the move to a smaller indoor environment would result in decreased overall behavioral activity. We also expected that nursery-reared monkeys would be more affected than their mother-reared counterparts. Measures of total activity and average activity in both the light and dark period did not significantly differ following relocation. Nor did the two early rearing groups differ. These data suggest that relocation does not substantially affect multiple measures of behavioral activity. Furthermore, the data suggest that middle-aged monkeys’ activity levels habituate readily following relocation; however, because we were unable to collect behavioral activity data during the initial quarantine period following relocation, we are unable to address any shorter-term changes in behavioral activity. These preliminary findings highlight the potential importance of collecting multiple quantitative measures to assess behavioral regulation following relocation in order to identify potential individual differences and the time-course of habituation.
