Fig. 2

A comparison of all samples. Comparison of real counting (RC) of nematodes marked in green against estimates from DM (red) and CEM (blue; n = 12 for each volume assessed). The asterisks denote statistical difference between methods compared with the same volume experiment: more asterisks represent more significance in the difference (* = 0.01; ** = 0.001 and *** = 0.0001)
