Correspondence analysis of the various lipid classes present in Baltic Sea cyanobacteria.

<p>Distribution patterns of (a) whole cell lipid distributions, (b) hydrocarbons, (c) fatty acid methyl esters, (d) bacteriohopanepolyols and (e) heterocyst glycolipids in the three genera of heterocystous cyanobacteria investigated. Dots indicate position of individual lipid biomarkers in relation to <i>Aphanizomenon</i> (square), <i>Dolichospermum</i> (triangles) and <i>Nodularia</i> (diamonds). Ellipses group the different genera of heterocystous cyanobacteria; <i>Aphanizomenon</i> (yellow), <i>Dolichospermum</i> (red) and <i>Nodularia</i> (blue).
