Distance-based redundancy analysis of phytobenthos community and environmental variables. dbRDA analysis resulting from DISTLM for sampling sites (white circle = site without D. geminata, black circle = sites with D. geminata). The environmental variables shown are those determined by the coefficient of determination R², with the most significant highlighted. The lower edge shows the taxa that contribute to 60% of the dissimilarity given by SIMPER between the sites that were invaded and not invaded by this microalga
