Ecological data for Huang et al. MS-Protist grazing increases heterocysts

Grazing by heterotrophic protists promotes heterocyst production in filamentous cyanobacteria, and this is closely associated with the macronutrient regeneration during the grazing process.异养原生生物（heterotrophic protists）对丝状蓝细菌（filamentous cyanobacteria）的摄食作用可促进其异形胞（heterocyst）生成，且该过程与摄食期间的大量营养素（macronutrient）再生紧密相关。
