“…Various studies have examined the effects of each of these three variables in detail (e.g. Plowman et al 2005;Todd et al 2006;Peng et al 2007), but a more encompassing approach is to evaluate the behaviour of captive animals with those found towards the ''wild'' end of the ''wild-captive continuum'' (Melfi and Feistner 2002;Hosey 2005).…”

This case study examines the activity budgets of captive Diana monkeys (Cercopithecus diana diana) and discusses results in the context of what is known regarding captive and wild-type behaviour in this species and other guenons. The activities of a family group of Diana monkeys (two parents and four offspring) housed at Edinburgh Zoo, UK, were quantified using a 5-min interval scan sampling technique. The 5100 observation points collected showed that the subjects spent the largest proportion of their time observing (approx. 46%), followed by feeding (approx. 15%), playing (approx. 11%), mutual grooming (approx. 8%) and resting (approx. 7%). The daily activity budgets for each of the subjects were tallied and, at the end of the 10-day observation period, used to produce a data matrix consisting of nine behaviour variables per subject. Clear among-individual differences in activity were identified with canonical discriminant function analysis. This multivariate approach illustrated how the combined behaviours of the parent male were distinct from those of the rest of the family group. Within the remainder of the group, the three youngest offspring displayed similar activity budgets, whereas the overall behaviour of the eldest offspring (a female) was between that of its siblings and her mother.

“…Although higher levels of aggressive behaviors have been shown for overcrowded captive groups of primates (Ha, Robinette, & Sackett, 1999;Plowman, Jordan, Anderson, Condon, & Fraser, 2005), some authors reported that appeasing behaviors more than aggressions resulted from crowding (Judge, Griffaton, & Fincke, 2006;Videan & Fritz, 2007). Other authors noted that all kinds of social encounters were avoided when density increased (Caws & Aureli, 2003;van Wolkenten, Davis, Gong, & de Waal, 2006).…”

Members of captive colonies of common marmosets (Callithrix jacchus), a small New World primate, can occasionally be victims of repeated, and potentially fatal, attacks by a family-mate. This study examined the records of a colony, looking for past instances of such aggressions. The aim was to better understand the possible causes underlying this phenomenon and to identify variables that could minimize their occurrence. The results showed that both males and females behaved as aggressors at the same rate, but females attacked just females, whereas males attacked both males and females. Most aggressions involved siblings and occurred at a higher rate when the cages were occupied by more than 5 nonhuman animals. The influence of group size was significant only when females behaved as aggressors. This study suggests that several factors can determine the occurrence of these aggressions and that their relative importance depends on the sex of the aggressor. The results of this study highlight the importance of collecting further data to verify whether crowding in a confined space, rather than group size per se, affects the incidence of these aggressions.

“…Objective information regarding if and how breeding and rearing young impacts welfare is needed in order to empower managers and conservation planners to make informed decisions about regulating reproduction in captive populations (Plowman et al, 2005). Chimpanzees are an important species with which to begin addressing the relationship between welfare and reproduction because they are highly represented in captivity, have well-developed cognitive capacities, and form long-lasting motheroffspring bonds.…”

Investigating the relationship between welfare and rearing young in captive chimpanzees (Pan troglodytes)

a b s t r a c tWhether the opportunity to breed and rear young improves the welfare of captive animals is currently debated. However, there is very little empirical data available to evaluate this relationship and this study is a first attempt to contribute objective data to this debate. We utilized the existing variation in the reproductive experiences of sanctuary chimpanzees at Chimfunshi Wildlife Orphanage Trust in Zambia to investigate whether breeding and rearing young was associated with improved welfare for adult females (N = 43). We considered several behavioural welfare indicators, including rates of luxury behaviours and abnormal or stress-related behaviours under normal conditions and conditions inducing social stress. Furthermore, we investigated whether spending time with young was associated with good or poor welfare for adult females, regardless of their kin relationship. We used generalized linear mixed models and found no difference between adult females with and without dependent young on any welfare indices, nor did we find that time spent in proximity to unrelated young predicted welfare (all fullnull model comparisons likelihood ratio tests P > 0.05). However, we did find that coprophagy was more prevalent among mother-reared than non-mother-reared individuals, in line with recent work suggesting this behaviour may have a different etiology than other behaviours often considered to be abnormal. In sum, the findings from this initial study lend support to the hypothesis that the opportunity to breed and rear young does not provide a welfare benefit for chimpanzees in captivity. We hope this investigation provides a valuable starting point for empirical study into the welfare implications of managed breeding.
