ABSTRACT Dinoflagellates are amongst the most abundant and diverse groups of plankton in surface waters and contribute to food web productivity and C:N:P biogeochemistry. Here we analyse the C:N:P of marine, autotrophic, planktonic dinoflagellates compiled from culture data from the scientific literature and test if dinoflagellate C:N:P differs from the Redfield ratio, and whether variability in C:N:P is associated with three traits: cell size, wall structure and toxin production. We find the average C:N:P of dinoflagellates is 90:12:1; higher in C:N, and lower in C:P and N:P than the canonical Redfield ratio. In aggregate the three traits examined here account for between 20–31% while taxonomic order accounts for between 37–38% of the variance in C:N:P. Smaller-sized and thecate taxa are higher in C:N, C:P and N:P than larger-size and athecate taxa. Species known to be able to produce C-rich toxins tend to be higher in C:P and N:P while species known to be able to produce N-rich toxins are lower in C:N, C:P and N:P relative to non-toxic species. These results indicate that any average estimate of dinoflagellate C:N:P will be influenced by the relative number of taxa with these traits.
期刊介绍:
The European Journal of Phycology is an important focus for the activities of algal researchers all over the world. The Editors-in-Chief are assisted by an international team of Associate Editors who are experts in the following fields: macroalgal ecology, microalgal ecology, physiology and biochemistry, cell biology, molecular biology, macroalgal and microalgal systematics, applied phycology and biotechnology. The European Journal of Phycology publishes papers on all aspects of algae, including cyanobacteria. Articles may be in the form of primary research papers and reviews of topical subjects.
The journal publishes high quality research and is well cited, with a consistently good Impact Factor.
