The model explained 77.8% of the total variation in the observed number of eggs per snail which was highly significant (PROC NLIN: F 3,729 = 853.8; P < 0.0001).

Though snail abundance initially showed an increasing trend followed by a persistent decline, this long-term pattern was seemingly overlaid by a seasonal variation, which was most apparent in snails collected prior to the wide scale use of metaldehyde in the eradication program ( Fig 2 ).
