A multi-phylum study of grazer-induced paralytic shellfish toxin production in the dinoflagellate Alexandrium fundyense: A new perspective on control of algal toxicity

Data cover a multi-phyla study of grazer-induced algal toxin production in the marine dinoflagellate Alexandrium catenella (formerly known as A. fundyense). The survey included seven species of grazer representing five phyla: the protists, Polykrikos kofoidii (Dinoflagellata) and Tiarina fusus (Ciliophora) the bivalve molluscs, Mytilus edulis and Mya arenaria (Mollusca), the ascidians, Molgula manhattensis and Botrylloides violaceus (Chordata), and the copepod, Eurytemora herdmani (Arthropoda). Independent variable: seven species of grazer, direct and indirect (kairomone and feeding-related cues) induction of toxin production, and total number of ingested cells ingested (cells per treatment). Dependent variables: toxicity (pgSTXeq per cell) and increase in toxicity (%) Data were published in: Senft-Batoh, C. D., Dam, H. G., Shumway, S. E., & Wikfors, G. H. (2015).
