微真核生物和细菌是水产养殖生态系统初级生产力和养分循环的关键驱动因素。尽管它们的多样性和组成已经在水产养殖系统中得到了广泛的研究，但微真核生物和细菌之间共生的二元网络仍然知之甚少。本研究利用高通量测序数据集的二部网络分析，检测了沿海水产养殖池塘水体和沉积物中微真核生物与细菌的共生关系。绿藻和真菌分别是水体和沉积物中微真核-细菌二元网络的优势门。绿藻与水中细菌的联系也被夸大了。大多数微真核生物和细菌被归类为多面手，并倾向于与水和沉积物中的细菌有对称的正负联系。然而，一些具有高密度链接的微真核生物与水中的细菌表现出不对称链接。双部网络的模块化检测表明，4种微真核生物和12种未培养细菌可能是模块连接的潜在关键类群。此外，沉积物中的微真核-细菌双部网络的巢性明显高于水中。微真核生物和多面手的减少将更有可能导致微真核生物和细菌在水和沉积物中积极共生关系的崩溃。本研究揭示了沿海水产养殖生态系统中微真核-细菌二元网络的拓扑结构、优势类群、关键物种和稳健性。这些物种可以应用于生态服务的进一步管理，这些知识也可能对其他富营养化生态系统的调节非常有用。在线版本包含补充材料，可在10.1007/s42995-022-00159-6获得。
Microeukaryotes and bacteria are key drivers of primary productivity and nutrient cycling in aquaculture ecosystems. Although their diversity and composition have been widely investigated in aquaculture systems, the co-occurrence bipartite network between microeukaryotes and bacteria remains poorly understood. This study used the bipartite network analysis of high-throughput sequencing datasets to detect the co-occurrence relationships between microeukaryotes and bacteria in water and sediment from coastal aquaculture ponds. Chlorophyta and fungi were dominant phyla in the microeukaryotic–bacterial bipartite networks in water and sediment, respectively. Chlorophyta also had overrepresented links with bacteria in water. Most microeukaryotes and bacteria were classified as generalists, and tended to have symmetric positive and negative links with bacteria in both water and sediment. However, some microeukaryotes with high density of links showed asymmetric links with bacteria in water. Modularity detection in the bipartite network indicated that four microeukaryotes and twelve uncultured bacteria might be potential keystone taxa among the module connections. Moreover, the microeukaryotic–bacterial bipartite network in sediment harbored significantly more nestedness than that in water. The loss of microeukaryotes and generalists will more likely lead to the collapse of positive co-occurrence relationships between microeukaryotes and bacteria in both water and sediment. This study unveils the topology, dominant taxa, keystone species, and robustness in the microeukaryotic–bacterial bipartite networks in coastal aquaculture ecosystems. These species herein can be applied for further management of ecological services, and such knowledge may also be very useful for the regulation of other eutrophic ecosystems.
