定义物种相互作用网络的组织并揭示其组合背后的过程是理解生物多样性、群落稳定性和生态系统功能模式的基础。海洋海绵拥有复杂的微生物群落，这些微生物群落有助于它们的健康和生存，但微生物组组装背后的机制在很大程度上是未知的。我们提出了全球海洋海绵微生物网络，并揭示了群落结构和功能的模块化组织。模块由一些与世界上其他物种共享微生物的海绵物种连接在一起。此外，我们提供的证据表明，当考虑到所有存在的微生物时，非生物因素会影响海绵微生物组的结构，但生物相互作用会推动更密切相关的“核心”微生物的组装。这些发现表明，生态和进化过程都在宿主-微生物网络组装中起作用。我们预计微生物组组装背后的机制在整个生命树的多细胞宿主中是一致的。
Defining the organisation of species interaction networks and unveiling the processes behind their assembly is fundamental to understanding patterns of biodiversity, community stability and ecosystem functioning. Marine sponges host complex communities of microorganisms that contribute to their health and survival, yet the mechanisms behind microbiome assembly are largely unknown. We present the global marine sponge-microbiome network and reveal a modular organisation in both community structure and function. Modules are linked by a few sponge species that share microbes with other species around the world. Further, we provide evidence that abiotic factors influence the structuring of the sponge microbiome when considering all microbes present, but biotic interactions drive the assembly of more intimately associated 'core' microorganisms. These findings suggest that both ecological and evolutionary processes are at play in host-microbe network assembly. We expect mechanisms behind microbiome assembly to be consistent across multicellular hosts throughout the tree of life.
