Data for: Interspecific interactions between gray woolly monkeys (Lagothrix lagotricha cana) and nine syntopic primate species

Assemblage structure and acquisition of high-value resources will usually be affected by changes in resource availability and differential competitive abilities of assemblage members. In fragmented habitats where carrying capacity limits are exceeded due to high population densities and biomass, interspecific interactions can be expected to occur at a high frequency, potentially turning into an important cost for coexistence. We studied assemblage- and guild-level patterns of interspecific interactions in two highly diverse isolated primate assemblages in southern Amazonia. Specifically, we assessed the effects of temporal variation in fruit availability on the rates of interspecific interactions between gray woolly monkeys (Lagothrix lagotricha cana), one of the largest tree-dwelling mammals of the Amazon forests, and nine syntopic primate species. This dataset includes the rates of interactions at the guild-level and assemblage-level, as well as the rates of interactions with each individual species. Additionally, the dataset provides estimations of fruit availability at both study sites.

集群结构与高价值资源的获取，通常会受到资源可获得性变化以及集群内成员竞争能力差异的影响。在因种群密度和生物量过高而超出环境容纳量阈值的破碎化生境中，种间相互作用的发生频率往往较高，有可能成为物种共存的重要代价。我们对亚马孙南部两个高度多样化且孤立的灵长类集群开展了研究，分析了其种间相互作用在集群层面和功能群层面的格局。具体而言，我们评估了果实可获得性的时间变化对灰绒毛猴（Lagothrix lagotricha cana）——亚马孙森林中体型最大的树栖哺乳动物之一——与9种同域分布灵长类物种之间种间相互作用发生率的影响。本数据集包含功能群层面和集群层面的相互作用发生率，以及与各单个物种的相互作用发生率。此外，本数据集还提供了两处研究样地的果实可获得性估算值。
