Figure 1
Variation in growth for eight different species of trematode parasitic castrators (operating stolen host bodies) and for both genders of uninfected horn snails. (A) Curves denote mean size-specific growth rates over the size-range sampled for each species (as estimated from a generalized linear model, Table 1). Species in legend are in the descending order of the growth curves as encountered at the mean-sized snail (705 mm3, or ~ 25.9 mm length), and sample sizes directly follow the species' names (Additional file 1, Table S1 lists the species' taxonomic families). (B) Variation in growth at the mean-sized snail. Results of pair-wise comparisons indicted. Bars sharing an equal-height line are not significantly different at the nominal P = 0.05 level. Asterisks denote additional non-significant differences when controlling for multiple comparisons by holding the False Discovery Rate to 0.05. Data in (A) and (B) represent 1,686 individuals spread throughout 17 sites in three southern California estuaries. Data standardized to reflect 3.5 months of growth in Carpinteria Salt Marsh channels. Other figures and the text use the species' letter and number codes.
