Fig. 5From: Ongoing niche differentiation under high gene flow in a polymorphic brackish water threespine stickleback (Gasterosteus aculeatus) populationProbability of frequency classes of Trematoda spp. cysts summed over the caudal, anal, dorsal, and both pectoral fins (upper figure), and probability of frequency classes of the crustacean copepod Theristina gasterostei on the inner side of operculum and gills (lower figure) found on the three Lake Engervann stickleback lateral plate morphs. Bars denote the whole population of sticklebacks in Lake Engervann with additional information on prevalence and intensity (standard deviation) for whole population and for the complete-, partial- and lowplated morphsBack to article page
