Fig. 5.

Geographical distribution of unicellular Holozoa OTUs from the Tara Oceans expedition. As depicted in the example (bottom left panel), chord diagrams show OTUs on the bottom half of the circle, and oceanic regions, depths, and fraction sizes on the upper half. Each OTU is represented by a line, whose thickness depicts the OTUs abundance in that particular place. In general, all unicellular holozoans were widespread and located in surface or DCM layers of the water column. However, some had different preferential geographical location (i.e., MAOP1 vs. MAOP2, or Craspedida vs. Acanthoecida), or fraction sizes (i.e., Ichthyophonida vs. Dermocystida, or Craspedida vs. Acanthoecida). Note that the thickness of each OTU is relative to the amount of OTUs in each group, so comparisons between lineages are not possible. Numbers below group names indicate the number of OTUs.
