Growth of the European taxonomic inventory.
Figures are generally photos, graphs and static images that would be represented in traditional pdf publications.
Cumulative number of valid species of European terrestrial and freshwater multicellular species since Linnaeus. A: All species. B: Birds, a virtually completely inventoried compartment of European biodiversity. C: Coleoptera, where the number of valid species has steadily increased and shows no sign of levelling. D: Acari, which remained neglected for two centuries, and are now exhibiting a high discovery rate. E: Platyhelminthes, where the impression of a saturated inventory could be due to a current lack of taxonomic workforce. F: Neuropterida orders, for which the rate of description is erratic and reflects bursts of activity by a handful of taxonomists.
