物种相互作用网络是由非生物和生物因素形成的。作为Tara Oceans项目的一部分，我们利用环境因子和生物丰度剖面研究了光区相互作用组，发现环境因子不能完全预测群落结构。我们发现浮游生物功能类型和系统发育类群之间的联系在网络上非随机分布，并受到局部和全球模式的驱动。我们确定了食草动物、初级生产者、病毒和（主要是寄生）共生体之间的相互作用，并使用显微镜验证了网络生成的假设，以确认共生关系。因此，我们为进一步研究海洋食物网和将生物成分整合到海洋模型中提供了资源。
Species interaction networks are shaped by abiotic and biotic factors. Here, as part of the Tara Oceans project, we studied the photic zone interactome using environmental factors and organismal abundance profiles and found that environmental factors are incomplete predictors of community structure. We found associations across plankton functional types and phylogenetic groups to be nonrandomly distributed on the network and driven by both local and global patterns. We identified interactions among grazers, primary producers, viruses, and (mainly parasitic) symbionts and validated networkgenerated hypotheses using microscopy to confirm symbiotic relationships. We have thus provided a resource to support further research on ocean food webs and integrating biological components into ocean models.
