In this study we used the daily activity pattern and use of space as indicators of change in the program of structural enrichment, implemented with 2 subjects of the species Ursus arctos in the Barcelona Zoo. We collected 930 sampling points in each study phase for each of the individuals: The samples were taken in a balanced way at different times of day. We observed a wider range of behavior in the male than the female. With respect to the indicators, we observed statistically significant differences in behavior in both individuals in the 2 study phases. Both individuals showed an increase in vigilance, maintenance, and inactivity when their enclosure was changed. In terms of the subjects' well-being, we considered the percentage of stereotyped behavior within acceptable limits. The percentage of activity observed in the male was very similar to that of individuals of this species in the wild. In terms of the use of space, we observed homogeneity only in the male during the enrichment program. The 2 individuals responded in different ways to the structural enrichment.
在本研究中，我们以日常活动模式和空间利用作为结构丰富化方案变化的指标，该方案在巴塞罗那动物园对2只棕熊个体实施。在每个研究阶段，我们为每个个体收集了930个采样点：样本在一天中的不同时间以平衡的方式采集。我们观察到雄性比雌性表现出更广泛的行为。关于这些指标，我们在两个研究阶段的两个个体的行为中观察到了统计学上的显著差异。当它们的围栏改变时，两个个体的警惕性、维持行为和不活动都有所增加。就受试者的福祉而言，我们认为刻板行为的百分比在可接受的范围内。观察到的雄性活动百分比与该物种在野外个体的活动百分比非常相似。在空间利用方面，我们仅在丰富化方案实施期间观察到雄性的空间利用具有同质性。这两个个体对结构丰富化的反应不同。
