Matteodo2016_Freq&Cover change

Species of the six plant communities and their corresponding frequencies in the historical and recent surveys, the difference between recent and historical frequency, the p-value derived from the permutation test on frequency, the mean cover in the historical and recent surveys, the difference of mean cover (recent-historical), and the significance value derived from the permutation test on cover. The latter test was applied only on species with historical and recent frequency values ≥ 25%. Species are ordered firstly by increasing p-values for the frequency test and secondly by increasing p-values for the cover test. Species with significant frequency or mean cover changes are in bold
