营养生态学中的几何框架方法假定动物试图平衡不同营养素的消耗，而不是简单地最大化能量增益。每种营养素的摄入目标都能最大化特定维度的适应度，因此，个体之间在摄入目标上的任何差异都代表了替代的行为和适应度最大化策略。营养相互作用是所有社会群体的核心组成部分，因此，摄入目标的任何个体间差异都应对社会动态产生重大影响。使用蜂群作为实验模型，我们量化的差异，在碳水化合物摄入量的目标，个别觅食使用毛细管馈线（CAFE）测定。我们的研究结果表明，蜜蜂并没有简单地最大化其净能量增益，而是将糖和水结合在饮食中，使它们达到相当于33%蔗糖溶液的摄入目标。虽然平均摄入量目标相对于营养素蔗糖和水是相同的，在不同的食物选择方案，有显着的个体间差异的摄入量目标和个人达到这一目标的方式，这表明不同水平的耐受性营养不平衡的变化。我们讨论了我们的研究结果的背景下，殖民地的表现可能会受到影响的不同的营养平衡策略的个体成员，以及如何这样的营养限制可能有助于社会性的进化。
The Geometric Framework approach in nutritional ecology postulates that animals attempt to balance the consumption of different nutrients rather than simply maximizing energetic gain. The intake target with respect to each nutrient maximizes fitness in a specific dimension and any difference between individuals in intake target therefore represents alternative behavioral and fitness maximization strategies. Nutritional interactions are a central component of all social groups and any inter-individual variation in intake target should therefore have a significant influence on social dynamics. Using the honeybee colony as an experimental model, we quantified differences in the carbohydrate intake target of individual foragers using a capillary feeder (CAFE) assay. Our results show that the bees did not simply maximize their net energetic gain, but combined sugar and water in their diet in a way that brought them to an intake target equivalent to a 33% sucrose solution. Although the mean intake target with respect to the nutrients sucrose and water was the same under different food choice regimens, there was significant inter-individual variation in intake target and the manner in which individuals reached this target, a variation which suggests different levels of tolerance to nutrient imbalance. We discuss our results in the context of how colony performance may be influenced by the different nutrient balancing strategies of individual members and how such nutritional constraints could have contributed to the evolution of sociality.
