Phytoplankton consumption by Macoma balthica.
The main orders of phytoplankton detected in the digestive tract of M. balthica, from selected samples sequenced after 23S rRNA gene metabarcoding, divided by phytoplankton fed (A; cyanobacteria Nodularia spumigena (brown), diatom Skeletonema marinoi (green), or not fed (gray)) and region (B; northern (red) and southern (blue) Stockholm archipelago). The size of the colored lines denotes the relative abundance (%) of the various taxa detected in the digestive tract of M. balthica.
