The primary goal of this project is to understand the nutritional drivers of Bornean orangutan foraging behavior. The project will be the first to test the assumption that orangutans maximize calories as part of their foraging strategy and will examine the nutrient priorities and balancing of orangutans to determine if protein is held at a constant level. Orangutan foraging may be a good model for the evolution of human dietary adaptations, because orangutans are large-bodied apes foraging in unpredictable habitats outside of the African rainforest, similar to early human ancestors. Understanding orangutan nutrient needs is also critical to the conservation of this endangered species. This project will be one of the first describing the importance of non-fruit orangutan foods, which are critical to conservation efforts. The research and findings are being shared with the Indonesian Parks Department to develop conservation strategies. Additionally, the project also will support international research collaborations and capacity building, and training of US students. This research will be conducted in Gunung Palung National Park, West Kalimantan, Indonesia, a field site that is unique in offering a mosaic of habitat types in which 2,500 wild orangutans range. Non-invasive full-day focal animal follows will yield a complete characterization of orangutan diet, with samples of every consumed food collected and analyzed for nutrient content. Using new statistical analysis techniques it is possible to test linear (optimal foraging, maximization or minimization theories) and geometric (nutrient balancing theories) models of orangutan foraging, and to determine if these strategies can co-exist. Improvements in GIS technologies, and the introduction of the Movement Ecology paradigm will allow an assessment of the goals of orangutan foraging and whether orangutans utilize landmark based navigation and certain movement patterns seen in humans.

这个项目的主要目标是了解婆罗洲猩猩觅食行为的营养驱动因素。该项目将是第一个测试红毛猩猩最大化卡路里作为其觅食策略的一部分的假设，并将检查红毛猩猩的营养优先级和平衡，以确定蛋白质是否保持在恒定水平。猩猩觅食可能是人类饮食适应进化的一个很好的模型，因为猩猩是大型猿类，在非洲雨林以外的不可预测的栖息地觅食，类似于早期人类祖先。了解猩猩的营养需求对保护这一濒危物种也至关重要。 该项目将是最早描述非水果猩猩食物重要性的项目之一，这对于保护工作至关重要。研究和调查结果正在与印度尼西亚公园部分享，以制定保护战略。此外，该项目还将支持国际研究合作和能力建设，以及美国学生的培训。这项研究将在印度尼西亚西加里曼丹的Gunung Palung国家公园进行，这是一个独特的野外遗址，提供了2,500只野生猩猩的栖息地类型。非侵入性的全天焦点动物跟踪将产生猩猩饮食的完整特征，收集每种食物的样本并分析营养成分。使用新的统计分析技术，可以测试线性（最佳觅食，最大化或最小化理论）和几何（营养平衡理论）模型的猩猩觅食，并确定这些策略是否可以共存。GIS技术的改进和运动生态学范式的引入将允许评估猩猩觅食的目标，以及猩猩是否利用基于地标的导航和在人类中看到的某些运动模式。
