Community trait space given by a PCOA of functional distances between all species (A). The green dot and drawing indicate the position of round goby. Red dots indicate the position of species classified as being the most distinct, while blue dots define species classified as most similar compared to the rest of the community. Names in bold indicate the position of the most functionally similar species to round goby B biplot of trait vectors and loadings showing which traits are influencing the position of each species in the PCOA C zoom of the central part of the biplot.
