女性的社会关系往往是由饮食资源的分配决定的。社会生态学模型预测，当资源聚集时，雌性应该形成严格的线性统治等级，当资源均匀分布时，雌性应该表现出更平等的社会结构。虽然许多食果动物和杂食动物确实表现出优势层次伴随着不同的资源访问，许多食叶动物偏离预期的模式和显示优势层次，尽管均匀分布的资源。在这些离群值，狒狒（Theropithecus gelada）提出了一个突出的难题，女性表现出积极的竞争和严格的统治阶层，尽管主要是在非垄断的草喂养。然而，这些草在旱季变得稀缺，狮尾狒狒用地下储存器官补充它们的饮食，这些器官需要相对广泛的能量来提取。我们测试了女性的统治阶层是否提供差异访问地下存储器官，通过评估等级，季节和喂养环境如何影响在西米恩山脉国家公园，埃塞俄比亚的长期研究的狮尾狒狒的侵略。我们发现，接收侵略的可能性是最高的地下喂养时，排名和侵略之间的反比关系是最极端的，而地下喂养在旱季。这些结果表明，狮尾狒狒的攻击围绕地下食物，这可能意味着地下储存器官是一个积极的中央饮食成分（尽管消费频率低于草），或者甚至“后备”食物可以影响喂养竞争和社会关系。进一步的工作应评估是否侵略在这种情况下是直接相关的高级别篡夺地下食物从低级别的女性提取后。
Female social relationships are often shaped by the distribution of dietary resources. Socioecological models predict that females should form strict linear dominance hierarchies when resources are clumped and exhibit more egalitarian social structures when resources are evenly distributed. While many frugivores and omnivores indeed exhibit dominance hierarchies accompanied by differential resource access, many folivores deviate from the expected pattern and display dominance hierarchies despite evenly distributed resources. Among these outliers, geladas (Theropithecus gelada) present a conspicuous puzzle; females exhibit aggressive competition and strict dominance hierarchies despite feeding primarily on non-monopolizable grasses. However, these grasses become scarce in the dry season and geladas supplement their diet with underground storage organs that require relatively extensive energy to extract. We tested whether female dominance hierarchies provide differential access to underground storage organs by assessing how rank, season, and feeding context affect aggression in geladas under long-term study in the Simien Mountains National Park, Ethiopia. We found that the likelihood of receiving aggression was highest when feeding belowground and that the inverse relationship between rank and aggression was the most extreme while feeding belowground in the dry season. These results suggest that aggression in geladas revolves around belowground foods, which may mean that underground storage organs are an energetically central dietary component (despite being consumed less frequently than grasses), or that even “fallback” foods can influence feeding competition and social relationships. Further work should assess whether aggression in this context is directly associated with high-ranking usurpation of belowground foods from lower-ranking females following extraction.
