原生浮游生物是开放水域海洋食物网的主要成员。传统上分为光养浮游植物和食养浮游动物，最近的研究表明，许多实际上结合联合收割机在一个细胞中的光养和食养;这些原生生物是“混合浮游生物”。在混合浮游生物范式下，“浮游植物”不能进行吞噬（硅藻是范例），而“浮游动物”不能进行光养。这一修订从区域到全球各级重新构建了海洋食物网。在这里，我们提出了第一个全面的海洋浮游混合生物数据库，汇集了这些生物的身份，异速生长，生理学和营养相互作用的现存知识。这mixoplankton数据库（MDB）将帮助研究人员面临的困难，在原生浮游生物的生命特征，它将有利于建模者需要更好地欣赏这些生物的生态与其复杂的功能和异速生长捕食者-猎物的相互作用。MDB还确定了知识差距，包括需要更好地了解不同的混合浮游生物功能类型，营养来源（硝酸盐的使用，猎物类型和营养状态），并获得生命率（例如生长，光合作用，摄入，影响光与噬菌体的因素）。现在可以重新审视和重新分类现存浮游生物生命形式数据库中的原生生物“浮游植物”和“浮游动物”，以澄清它们在海洋生态系统中的作用。
Protist plankton are major members of open‐water marine food webs. Traditionally divided between phototrophic phytoplankton and phagotrophic zooplankton, recent research shows many actually combine phototrophy and phagotrophy in the one cell; these protists are the “mixoplankton.” Under the mixoplankton paradigm, “phytoplankton” are incapable of phagotrophy (diatoms being exemplars), while “zooplankton” are incapable of phototrophy. This revision restructures marine food webs, from regional to global levels. Here, we present the first comprehensive database of marine mixoplankton, bringing together extant knowledge of the identity, allometry, physiology, and trophic interactivity of these organisms. This mixoplankton database (MDB) will aid researchers that confront difficulties in characterizing life traits of protist plankton, and it will benefit modelers needing to better appreciate ecology of these organisms with their complex functional and allometric predator–prey interactions. The MDB also identifies knowledge gaps, including the need to better understand, for different mixoplankton functional types, sources of nutrition (use of nitrate, prey types, and nutritional states), and to obtain vital rates (e.g. growth, photosynthesis, ingestion, factors affecting photo’ vs. phago’ ‐trophy). It is now possible to revisit and re‐classify protistan “phytoplankton” and “zooplankton” in extant databases of plankton life forms so as to clarify their roles in marine ecosystems.
