I focused on environmental factors and clarified what "environmental conditions" were important in formation of multi-level society in proboscis monkeys. Environmental condition in this study means the vegetation patterns : mangrove and riverine forest. In this study, I clarified the ecology and social structureof proboscis monkeys inhabiting mangrove forest, and then evaluated the effects of environmental condition on their social structure in mangrove forest by comparing ecology and social structure of proboscis monkeys inhabiting riverine forest in my former study. The activity budget of proboscis monkeys in the mangrove forest was different from that in the riverine forest : proboscis monkeys in the mangrove forest spent more time for feeding and more time for fruit-eating compared to those in the riverine forest. In addition, the dietary diversity of proboscis monkeys in the mangrove forest was extremely lower than that in the riverine forest. Base on the data of the locations of proboscis monkey groups along the river, we clarified the significant effects of the environmental factors, especially food availability and predation pressure, on the degree of the cohesiveness among the groups in the riverine forests. However, the degree of the cohesiveness among the groups in the mangrove forest seemed to be influenced by strongly food availability.

我把重点放在环境因素，并澄清了什么样的“环境条件”是重要的，在形成多层次社会的长鼻猴。研究中的环境条件是指植被类型：红树林和河岸林。本研究首先阐明了栖息于红树林的长鼻猴的生态和社会结构，然后通过与以往栖息于河流林长鼻猴的生态和社会结构的比较，评价了环境条件对红树林长鼻猴社会结构的影响。红树林中长鼻猴的活动预算与河岸林中长鼻猴的活动预算不同：红树林中长鼻猴的觅食时间和食果时间均多于河岸林。此外，红树林长鼻猴的食物多样性显著低于河岸林。通过对长鼻猴群沿着分布的研究，阐明了环境因素，尤其是食物可获得性和捕食压力对河流森林中长鼻猴群群体间凝聚力的影响。然而，红树林内种群间的凝聚力似乎受到食物可利用性的强烈影响。
