A Thesaurus of Plant Characteristics for Ecology and Evolution

TOP, a Thesaurus Of Plant characteristics, 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 characteristics: plant traits and environmental associations.

TOP can be searched via :

  • FACETED SEARCH, filtering the available information by grouping terms into facets
  • HIERARCHY SEARCH, providing a tree that progressively unfolds and a search field where terms or TOP identifiers can be entered
  • INDEX, a complete alphabetical list of all concepts defined in TOP

Regular updates of TOP are planned based on community involvement.
