Fig. 5From: Trematode diversity reflecting the community structure of Danish freshwater systems: molecular cluesParasite–host transmission patterns. Note: circles in the middle represent second intermediate hosts in the freshwater environment and circles at the top represent the definitive host groups. The lines indicate trematode species utilizing individual transmission pathways, with the thickness of the lines being proportional to the number of trematode species utilizing each transmission pathway.
