Figure 1 in Exposure of the snail Potamopyrgus antipodarum to herbicide boosts output and survival of parasite infective stages

Figure 1. Mean (±SE) number of cercariae emerging per day from individual snails, P. antipodarum, exposed to either control water, low, medium or high concentrations of the herbicide glyphosate. Data are shown separately for the trematodes C. parvum (N = 6 snails for each treatment), Apatemon sp. (N = 3), and an undescribed renicolid species from two localities (Tomahawk Lagoon, N = 12; Lake Waihola, N = 9). In each case, different letters on the bars indicate mean values that are significantly different (Tukey–Kramer tests, P <0.05).
