NAL Call Number: QL737.P9A5
Abstract: No consensus exists about the quantity and variety of environmental enrichment needed to achieve an acceptable level of psychological well-being among singly housed primates. Behavioral and plasma and fecal cortisol measures were used to evaluate the effectiveness of four levels of toy and foraging enrichment provided to eight wild-caught, singly housed adult male brown capuchins (Cebus apella). The 16-week-long study comprised six conditions and began with a 4-week-long preexperimental and ended with a 4-week-long postexperimental period during which the subjects were maintained at baseline enrichment levels. During the intervening 8 weeks, the subjects were randomly assigned to a sequence of four 2-week-long experimental conditions: control (baseline conditions), toy (the addition of two plastic toys to each cage), box (access to a foraging box with food treats hidden within crushed alfalfa), and box & toy (the addition of two plastic toys and access to a foraging box). Behavioral responses to changes in enrichment were rapid and extensive. Within-subject repeated-measure ANOVAs with planned post hoc contrasts identified highly significant reductions in abnormal and undesirable behaviors (and increases in normal behaviors) as the level of enrichment increased from control to toy to box to box & toy. No significant behavioral differences were found between the control and pre- and postexperimental conditions. Plasma and fecal cortisol measures revealed a different response to changing enrichment levels. Repeated-measure ANOVA models found significant changes in both these measures across the six conditions. The planned post hoc analyses, however, while finding dramatic increases in cortisol titers in both the pre- and postexperimental conditions relative to the control condition, did not distinguish cortisol responses among the four enrichment levels. Linear regressions among weekly group means in behavioral and cortisol measures (n=16) found that plasma cortisol was significantly predicted by the proportions of both normal and abnormal behaviors; as the proportion of normal behaviors increased, the plasma cortisol measures decreased. Plasma cortisol weekly group means were also significantly and positively predicted by fecal cortisol weekly group means, but no behavioral measure significantly predicted fecal cortisol weekly group means. In sum, these findings argue strongly that access to a variety of toy and foraging enrichment positively affects behavioral and physiological responses to stress and enhances psychological well-being in singly housed brown capuchins.

Abstract: Captive environment influences animal behavior and may cause damage to the health of the individuals. This study had the objective of proposing one suitable environment which could maintain the captivity welfare. Different techniques of environmental enrichment were applied to thirteen spider-monkeys (Ateles spp.) in three different captive environments, with different vegetation and animal composition. Individuals and social behaviors were observed for 309 hours, from February 13th to August 10th, 2006 at Passeio Publico and the Zoological Garden, Curitiba, Parana, Brazil. The observations were organized in three phases: control, experimental (application of the environmental enrichment activities) and the response to enrichment. Different responses to enrichment show that animals from this genus, when maintained in group in an area proportional to the number of individuals, whose vegetation is composed of trees, have better opportunity to express their species behaviors.

Abstract: We studied the manipulative activity of five wedge-capped capuchins (Cebus olivaceus) confronted with different types of unfamiliar and portable objects: wooden blocks, plastic rings, spoons, and coconuts. Combinatorial manipulations involving two portable objects of the same type were quite frequent. The lately introduced objects, whatever their kind, appeared as the most attractive. Nevertheless, some objects remained very attractive throughout the overall experiment, especially the wooden blocks which elicited more combinatorial and striking behaviors than the other objects. Concerning space, we observed that the individuals choose specific locations to perform their manipulative acts. The spatial distributions of these acts were more concentrated, and less concordant between individuals, in the present study than in two others conducted with the same group but involving the manipulation of familiar objects. This suggests that individual differences were more marked when the subjects manipulated unfamiliar objects than when they manipulated familiar ones. This finding may have applications when the members of a group have to benefit from an enrichment of their environment.

NAL Call Number: SF405.5.A23
Abstract: We investigated the use of artificial turf foraging boards to determine if providing captive squirrel monkeys an opportunity for semi-natural foraging behavior would 1) alter the monkeys' time budget to better approximate that seen in wild populations, 2) reduce the stereotypic, self-injurious, and aggressive behavior occasionally seen in captive squirrel monkeys, and 3) provide sustained enrichment. Five groups of pair-housed female squirrel monkeys were videotaped the week prior to, the week following, and for 2 weeks during the enrichment phase, when treat-enhanced boards were provided for 2 h daily. During the first 30 min of daily enrichment, inactivity declined 35.3%, locomotion increased 3.8%, and board-related behaviors occupied 36.3% of the activity budget; these changes were not evident after 1.5 h. Stereotypic behavior (pacing, headswinging, tailchewing) and aggression were not altered by the foraging opportunity. The foraging board retained the interest of the subjects across 2 weeks in the same daily pattern. Use of the foraging board altered the squirrel monkeys' time budget to become more like activity patterns seen in wild populations.
