Map of the sampling area in the Elbe River with the Aquatic Invasion corridors: A – Central Corridor, B – Southern Corridor. Sampling localities are marked by stars: 1 – the Süderelbe, 2 – Geesthacht, 3 – Ústí nad Labem

Non-metric multidimensional scaling (NMDS) based on Jaccard and Bray-Curtis dissimilarities in parasite communities found in round goby (Neogobius melanostomus) from the Süderelbe (black points), Geesthacht (gray points) and Ústí nad Labem (open points). Fish with parasite assemblages too distant from all other fish are not presented (i.e. fish with no parasites or with only one specimen not present in any other fish)
