F I G U R E 3 in GIFT – A Global Inventory of Floras and Traits for macroecology and biogeography

F I G U R E 3 Trait processing in the Global Inventory of Floras and Traits (GIFT). Original trait records entering GIFT are subjected to three processing steps: (i) Trait values are standardized with respect to language, terminology and measurement unit. (ii) Additional trait values are derived hierarchically for traits that are logically nested (colored rows under "derived traits", see also Figure S1), and taxonomically for species that belong to taxonomic groups that are uniform with respect to a particular trait. (iii) Derived trait values are aggregated at the species level based on the consensus among resources (categorical traits) or summary statistics are computed based on the original values (numerical traits) [Colour figure can be viewed at wileyonlinelibrary.com]
