Alnus glutinosa Riparian Woodlands of Italy and Corsica: Phytosociological Classification and Floristic Diversity
2022
A comparative analysis of the riparian vegetation dominated by Alnus glutinosa in Italy and Tyrrhenian islands, based on literature data and unpublished relevés, is presented. A total of 456 phytosociological relevés were processed. For the definition of plant communities and alliances, hierarchical clustering was performed by using Bray-Curtis coefficient and Detrended Correspondence Analysis ordination methods. Identification of diagnostic species of the vegetation units was performed by means of the phi fidelity index. Quantum GIS software version 3.6 was used for the interpolation of the bioclimatic variables and A. glutinosa communities. Overall, a total of 18 A. glutinos…
Unpublished aspects of hygrophilous wood vegetation from Nebrodi mountains (N-E Sicily)
2021
In this paper we report the results of a study done on the vegetation of hygrophilous woods and shrubs occurring along the sub montane and montane small rivers of the Alcantara watershed located in the Nebrodi Mountains (N-E Sicily). We have described two new associations: Alno glutinosae-Salicetum rubentis and Euonymo europaei-Salicetum lambertianae, both belonging to the class Salici purpureae-Populetea nigrae. The forest association would belong to the alliance Populion albae of the order Populetalia albae, while the shrubs of pebbly streams would give origin to communities that would belong to the alliance Salicion albae of the order Salicetalia purpureae. The study gave the occasion to…
