TOP-Thesaurus

"The TOP-Thesaurus defines standards for a functional approach to plant diversity by stabilizing the terminology for concepts widely used in ecology and evolution. TOP provides names, definitions, formal units and synonyms for more than 700 plant features: plant traits, environmental preferences and spatial distribution. TOP can be searched via: FACETED SEARCH, filtering the available information by grouping terms into facets; HIERARCHY SEARCH, providing a tree that progressively unfolds; INDEX, a complete alphabetical list of all concepts defined in TOP. Regular updates of the TOP-Thesaurus are planned based on community involvement."
