From: Assembly processes and functional diversity of marine protists and their rare biosphere
Assembly processes across protistan taxonomic divisions and size fractions. Taxonomic divisions (axis y) were sorted by supergroups. Assembly processes were inferred from the distribution of the OTUs in each taxonomic subset using the method of Stegen et al. [14]. Assembly processes were converted into types of rarity following the nomenclature of ref [5]. Patterns from unclassified OTUs (at the division level) were also computed in each size fraction, although they do not represent a coherent taxonomic group
