Abundance and calculated biomass of the cyanobacterium Richelia intracellularis as an epiphyte of the diatom Chaetoceros compressus in the western Pacific Ocean

Richelia counts are derived from host diatom cell counts: assuming each host Chaetoceros contains 0.5 Richelia trichomes, each Hemiaulus contains 2 Richelia trichomes and each Rhizosolenia contains 5 Richelia trichomes. Also assumes each Richelia trichome contains 5 cells.
