Predator-prey interactions between the heterotrophic protist Polykrikos kofoidii and two Alexandrium strains: the non-lytic paralytic shellfish toxins (PST) producing A. catenella and the lytic goniodomins (GD) producing A. pseudogonyaulax

The ingestion rates of the heterotrophic protist Polykrikos kofoidii feeding on two different species of Alexandrium were determined by means of incubation experiments in well-plates. In this experiment P. kofoidii was subjected to monoalgal prey consisting of either A. pseudogonyaulax (strain L4-B9) or Alexandrium catenella (strain Alex 5). This dataset contains all data collected within the experiment including cell counts and ingested prey cells of P. kofoidii. The experiments were carried out between December 2 and 5, 2022 in the laboratories at the Alfred-Wegener-Institute in Bremerhaven, Germany.

本研究通过多孔板孵育实验，测定了异养原生生物科氏多角藻（Polykrikos kofoidii）取食两种亚历山大藻（Alexandrium）物种的摄食率。实验中，科氏多角藻的单一藻类饵料分别为假甲藻亚历山大藻（A. pseudogonyaulax，菌株L4-B9）或链状亚历山大藻（Alexandrium catenella，菌株Alex 5）。本数据集包含本次实验采集的全部数据，涵盖科氏多角藻的细胞计数结果及其摄食的猎物细胞数。实验于2022年12月2日至5日期间，在德国不来梅港阿尔弗雷德·魏格纳研究所（Alfred-Wegener-Institute）的实验室中开展。
