The site of Rossens, which is the most diverse, has been chosen to apply the methodology of the integrated synusial phytosociology which considers several spatio-temporal organizational levels. The synusiae of seven phytocoenoses are described. Using floristic and ecological comparisons, their integration in higher organizational levels (tesela, catena) is discussed.floodplainscommunity structurephytocoenosissynusiateselacatenaThe methodology of integrated synusial phytosociology applied to a floodplain sector of the Sarine River, Switzerlandtext::journal::journal article::research article
