Fig. 5. Linear regression of the diversity of the most diverse families as a function of the number taxa assigned (a), the number of OTUs (b), the asymptotes of the OTUs accumulation curves (c) ; and differences between the number of taxa assigned (d), the number of OTUs (e), the asymptotes of OTUs accumulation curves (f) and the number of species in the checklist as a function of the number of species in the checklist. Only the families with a number of OTU and a number of species in the checklist ≥ 10 are presented to provide accurate estimations.
