Alpha diversity of Galba truncatula snail samples stratified by farm, presented at the genus level. a Comparison of observed richness revealing no significant differences in alpha diversity between snails collected from each farm (P-value = 0.98; Mann–Whitney U statistic = 84). b Comparison of Chao1 richness revealing no significant differences in alpha diversity between snails collected from each farm (P-value = 0.98; Mann–Whitney U statistic = 84). c Comparison of Shannon’s diversity index revealing no significant differences in alpha diversity between snails collected from each farm (P-value = 0.98; Mann–Whitney U statistic = 86). d Comparison of Simpson’s diversity index revealing no significant differences in alpha diversity between snails collected from each farm (P-value = 0.71; Mann–Whitney U statistic = 77). e Comparison of Fisher diversity index revealing no significant differences in alpha diversity between snails collected from each farm (P-value = 0.90; Mann–Whitney U statistic = 82). The numbers 1 and 2 to right of boxplots refer to Farm 1 (sheep farm located in County Antrim, in orange) and Farm 2 (with approximately 50 cattle, located in County Tyrone, in blue), respectively
