Influence of predator-prey evolutionary history, chemical alarm-cues and feeding selection on induction of toxin production in a marine dinoflagellate

Data include induced toxin production in the marine dinoflagellate Alexandrium catenella (formerly known as A. fundyense). The hypothesis that history of co-occurrence between predator and prey affects the ability of prey to recognize and respond to predators with increased toxin production was tested for this copepod-alga interaction. Independent variable: direct and indirect induction of toxin production, algal alarm-cue, and feeding selectivity Dependent variables: toxicity (pgSTXeq per cell) and ingestion rate (cells per copepod per hour) Data were published in: Senft-Batoh, C. D., Dam, H. G., Shumway, S. E., Wikfors, G. H., & Schlichting, C. D. (2015).

本数据集包含海洋甲藻链状亚历山大藻（Alexandrium catenella，曾用名A. fundyense）的毒素诱导产生相关数据。针对该桡足类-藻类互作体系，本研究验证了“捕食者与猎物的共现历史会影响猎物识别捕食者，并通过提升毒素合成量作出响应的能力”这一假说。
本实验设置的自变量包括：毒素产生的直接诱导与间接诱导、藻类警报信号（alarm-cue）以及摄食选择性；因变量包括：毒性（每细胞pgSTXeq）与摄食率（每桡足类每小时摄食细胞数）。
