Table 3 Similarity percentage analysis (SIMPER). Average abundance values are shown for phytobenthos species at sites non-invaded (LIU) and invaded (MAR, TAL, and LOL) by D. geminata. The comparison between both sites is shown, along with average dissimilarity values and contribution percentages (%). Bacillariophyceae (B), Cyanophyta (C), Chlorophyta (Ch)
