Estimates extrapolated to ENS (a) and NSS (b). Comparison among the real counting of nematodes (RC) marked in green against the estimates of DM (red) and CEM (blue; n = 12 for each volume assessed). The asterisks denotes statistical difference between methods compared with the same experimental volume, with more asterisks representing a more significant difference (* = 0.01; ** = 0.001 and *** = 0.0001)
