栖息地和觅食生态学的知识对于为受威胁的灵长类动物制定有效的保护管理计划至关重要。尽管在近十年前被重新发现，但人们对极度濒危的长臂猿(Nomascus Nasutus)或其栖息地知之甚少。我们分析了森林覆盖率，对当地长臂猿进行了直接观察和访谈，以更好地了解森林变化，并确定对长臂猿生存至关重要的森林特征和物种。访谈表明，人类对森林资源的开发侧重于物种特有和最容易获得的较大树木。长臂猿森林生境由四种主要森林类型组成。整个站点的平均冠层高度为10.52m。长臂猿消耗了81种，几乎占该站点记录的乔木和藤本植物的一半，但只有19种植物提供了77.8%的食物。在整个遗址的历史上，19种食物中的6种都是出于不同的原因被记录下来的。我们的结论是，对分布高度有限、饮食需求集中的灵长类动物和退化生态系统的有效保护管理将需要积极的森林恢复，例如在退化地点种植重要的食物物种。(C)2011爱思唯尔有限公司。保留所有权利。
Knowledge of habitat and feeding ecology is essential for developing an effective conservation management plan for threatened primates. Despite having been rediscovered nearly a decade ago, very little is known of the critically endangered cao vit gibbon (Nomascus nasutus) or its habitat. We analysed forest cover, made direct observations and conducted interviews of local elders to better understand forest changes and to determine the forest characters and species important to the survival of the gibbon. Interviews indicated human-induced forest resource exploitation focused on species-specific and larger trees most easily accessed. Gibbon forest habitat comprised four primary forest types. The mean canopy height over the whole site was 10.52 m. Gibbons consumed 81, or nearly half of the tree and liana species recorded in the site; however, only 19 species provide 77.8% of the diet. Six of the 19 food species were logged for different reasons throughout the history of the site. We conclude that effective conservation management of primates with highly limited distributions, focused dietary needs, and in degraded ecosystems will require active forest restoration, such as planting important food species in degraded sites.
