Figure 2From: The metazoan parasite communities of the shoal flounder (Syacium gunteri) as bioindicators of chemical contamination in the southern Gulf of MexicoGroupings based on the parasite species of Syacium gunteri shared among sampling sites. The dendogram was produced using the unweighted pair-group method (UPGMA) and Jaccard’s similarity index. Note that the symbols for groups 1 (), 2 (), and 3 () are the same as in Figure 1.Back to article page
