At high elevations, biodiversity is at elevated risk from extinctions due to rapid environmental changes. In the most of its range in Himalayas, the red panda, an endangered species, is struggling to survive in the wild, and a global captive breeding programme has been launched to conserve the species. Because captivity can have negative impacts on animals, reducing the chance of successful reintroduction, we investigated the predictors of stereotyped behaviour and behavioural diversity of red panda (n = 26), and the effect of stereotypy on their behavioural diversity in three Indian zoos. Multivariate analysis showed that stereotypy increased with density of logs on the ground, age and higher among pandas in zoo 3 compared to zoo 2, but decreased with number of nests, sociality, tree density and tree height used. Similarly, behavioural diversity increased with log density, but decreased among pandas in zoo 2 compared to zoo 1, during summer compared to winter, and also with ambient temperature, stereotypy, tree density, and tree height used. The relationship between stereotypy and behavioural diversity was negative, but not significant. Provision of a greater density of trees was associated with higher levels of daytime inactivity. Findings from this study have global relevance, as the captive red panda experiences similar welfare issues around the world, and our data provide empirical support for some existing guidelines for red panda husbandry.
在高海拔地区,由于环境的快速变化,生物多样性面临着灭绝的高风险。在喜马拉雅山的大部分地区,作为濒危物种的红熊猫正在野外艰难求生,因此全球范围内发起了圈养繁殖计划以保护该物种。由于圈养可能对动物产生负面影响,降低了成功再引入的机会,我们研究了刻板行为和红熊猫行为多样性的预测因素(n=26),以及刻板行为对三个印度动物园中红熊猫行为多样性的影响。多变量分析表明,刻板行为随着地面上原木密度、年龄和动物园 3 中熊猫的增加而增加,但随着巢穴数量、社会性、树木密度和使用的树木高度的增加而减少。同样,行为多样性随着原木密度的增加而增加,但与动物园 1 相比,动物园 2 中的熊猫在夏季比冬季减少,与环境温度、刻板行为、树木密度和使用的树木高度也减少。刻板行为与行为多样性之间呈负相关,但不显著。提供更多的树木密度与白天活动减少有关。本研究的结果具有全球相关性,因为圈养红熊猫在全球范围内都面临着类似的福利问题,我们的数据为红熊猫饲养的一些现有准则提供了经验支持。
