Növényi jellegek és alkalmazásuk növényökológiai kutatásokban I.: Történeti áttekintés, jelleg típusok, módszertan és adatbázisok

The importance of studies based on plant functional traits is indicated by the huge number of papers (more than 5000) published in the last 15 years in this topic. In community ecology the recent trend of studying organisms on the functional- rather than on the taxonomic level is quite significant. In this review we attempted to summarise the applicability of functional plant traits commonly used in ecological studies. We discussed the levels of functional categorisation, described the different plant strategies based on functional traits and emphasised the usage of standardised measurements. The most outstanding trait databases are introduced here, showing their availability, content and specialities. This review is intended as an introduction to the topic and can later be completed by papers elaborating on how plant functional traits are used in theoretical and applied plant ecology.
