Figure 4 Complexity x Enrich Zone Partial Correlations Correcting for Enclosure Size Leopards Housed On- and Off-Exhibit in Four Zoos in Southern India revealed that activity levels were significantly higher in structurally enriched enclo- sures (Mann—Whitney U: Z=-—2.780, N= 15, p = .004; see Figure 4). There was no significant difference in the proportion of stereotypic behavior exhibited in the structurally enriched and barren enclosures (Mann-Whitney U: Z=—1.273, N=15,p = .232). There was no significant difference in behavior exhibited in structurally en- riched and barren off-exhibit enclosures (Mann—Whitney U: activity behavior, Z=
