Fig 1.
Phylogenies of the number of species in different policy relevant categories.
Number of species in (A) the taxonomic research-needed category in IUCN Redlists; (B) the European Red List; (C) the European crop wild relatives; (D) the invasive alien species on the horizon for future invasions; (E) the Union List of Concern for invasive species; (F) the species named in the European Birds Directive; (G) the species named in the European Habitats Directive; (H) the species named in the European Marine Framework Directive and (I) the species important to the European Pollinator Initiative. The colour gradient in the heat trees ranges from yellow (low values) to blue (high values), with grey denoting the absence of species.
Table 2.
A summary of the taxonomic journal selection results. Journals related to taxonomy and their relation to other journal identifiers. Only active journals with an OpenAlex ID were used to select taxonomic articles.

Phylogenies of the publication activity of taxonomists separated into the kingdoms (A) Plantae (B) Fungi and (C) Animalia.
Tips represent orders, but only some classes and higher taxa are labeled.
