Ellenberg’s Indicator values for the Flora of Italy – first update: Pteridophyta, Gymnospermae and Monocotyledoneae

摘要

Ellenberg’s indicator values are an useful tool to delineate the relationship between plants andudenvironment, recognising to each species a functional role as biological indicator. In the frameudof the second edition of the Pignatti’s “Flora d’Italia”, some new informative systems are underudpreparations, in order to support geobotanical/applied studies, including a complete and updatedudreview of the Ellenberg’s indicator values for the whole bulk of species mentioned in theudflora of Italy. This first contribution includes a list of 380 species of Pteridophyta,udGymnospermae and Monocotiledoneae that complete the first assignment of the Ellenberg’sudindicator values to the flora of Italy, published in 2005. Besides, some methodological considerationsudon the attribution and the use of Ellenberg’s indicator values are reported.
