Different plant communities hosting Ionopsidium savianum (Caruel) Arcang. in Tuscany: taxonomic and functional diversity.

This research analyses two different plant communities hosting Ionopsidium savianum (Caruel) Arcang., a species of European concern (Gigante et al. 2014). They occur in areas ecologically very different, particularly concerning the substratum type: limestone (Monte Calvi) and serpentine (Monte Pelato). The communities have been analyzed focusing on taxonomic and alfa and beta diversity, functional diversity and ecological strategies sensu Grime. We can conclude that the two communities differ signifiicantly from each other, confirming that the substrate type leads to relevant taxonomic ecological and functional differences.
