Fig. 1 in Fatty acids as chemotaxonomic and ecophysiological traits in green microalgae (desmids, Zygnematophyceae, Streptophyta): A discriminant analysis approach

Fig. 1. Linear discriminant analysis based on fatty acid profiles of desmid strains belonging to the climate-origin group. (a) Discrimination of the clusters (tropical, subtropical, moderate, and polar) at the start of cultivation (2 days). (b) Discrimination of the clusters (tropical, subtropical, moderate, and polar) at the end of cultivation (24 days). DF1 – the first discrimination function; DF2 – the second discrimination function; red triangles – tropical strains; orange quadrangles – subtropical strains; green pentangles – strains from moderate climate; blue circles – polar strains.
