(Supplement 4) Selective feeding of dinoflagellate in the Microscopy experiment

This dataset comprises data from two experiments analysed with two different tools, a FlowCam and a microscope. The heterotrophic dinoflagellate Oxyrrhis marina was subjected to different feeding treatments (starved, or fed with either F/2 nutrient reach, nitrogen-limited, or phosphorus-limited phytoplankton of the species Rhodomonas salina). The carbon:nitrogen:phosphorus stoichiometry of the different phytoplankton and dinoflagellate cultures was measured. The nitrogen-limited and phosphorus-limited phytoplankton were mixed and the mixture was offered as food to the dinoflagellates previously fed on either nitrogen-limited, or phosphorus-limited phytoplankton. The selective feeding of the dinoflagellate on the two mixed algal qualities was measured.本数据集涵盖两项实验的相关数据，所有数据均通过FlowCam（FlowCam）与光学显微镜两种不同设备完成分析。实验所用的异养甲藻为海洋尖尾藻（Oxyrrhis marina），研究人员对其设置了多种摄食处理方式：包括饥饿处理，以及分别投喂采用F/2培养基培养的营养充足、氮限制或磷限制的盐生红胞藻（Rhodomonas salina）浮游植物。本研究测定了不同浮游植物与甲藻培养物的碳:氮:磷化学计量比。随后将氮限制与磷限制的浮游植物进行混合，将该混合物作为食物投喂给此前分别以氮限制或磷限制浮游植物为食的海洋尖尾藻，并测定了该甲藻对两种不同品质混合藻类的选择性摄食情况。
