The global distribution of plants used by humans.

Plants sustain human life. Understanding geographic patterns of the diversity of species used by people is thus essential for the sustainable management of plant resources. Here, we investigate the global distribution of 35,687 utilized plant species spanning 10 use categories (e.g., food, medicine, material). Our findings indicate general concordance between utilized and total plant diversity, supporting the potential for simultaneously conserving species diversity and its contributions to people. Although Indigenous lands across Mesoamerica, the Horn of Africa, and Southern Asia harbor a disproportionate diversity of utilized plants, the incidence of protected areas is negatively correlated with utilized species richness. Finding mechanisms to preserve areas containing concentrations of utilized plants and traditional knowledge must become a priority for the implementation of the Kunming-Montreal Global Biodiversity Framework.

Paolo Boccone and the visual communication of pre-Linnean botany. A comparison between his Leiden herbarium, Paris autoprint and published Icones (1674).

This article addresses the development of visual practices in early modern Botany by focusing on the diverse strategies of graphic representation of plant species. Naturalis Biodiversity Center holds a historic herbarium of 169 sheets with specimens of Mediterranean plants collected by the Sicilian Botanist Paolo Boccone (1633-1704). Part of Boccone's dried specimens served as model for the etchings published in his Icones et descriptiones rariorum plantarum (1674) and part of them were used as matrix for at least one album of botanical autoprints kept in Paris. The exceptional survival of the three collections: the original dried specimens, their autoprint impressions and the etched illustrations of the book, offers a unique insight in the material and intellectual issues addressed in the process of visual representation of plants in early modern Botany. Here we present the first scientific comparison of these three valuable 17th century botanical collections. Visual comparison revealed that the Leiden collection provided 64 specimens to Icones, while 44 specimens show a perfect matching with the autoprint impressions. In nine cases the Leiden specimens appear both in the autoprints and in the Icones, thus showing the complete process of visual translation of the plant preliminary to its wider circulation in the scientific community.
