Figure 1

Schematic representation of the 21 phytoplankton mock communities. Each of the seven groups (see Materials and methods) is represented by three communities, which differ in taxa abundances (i.e., number of cells; see Table 2); A = Alexandrium minutum, B = Chaetoceros socialis; C = Pseudo-nitzschia spp., D = Scrippsiella spp., E = Alexandrium pacificum, F = Skeletonema marinoi, G = Thalassionema frauenfeldii.
