Fig. 3. Biomass loss (and gain) of rice hills in the presence of Pomacea canaliculata
relative to snail-free controls after 7 days in experimental arenas with (A) large snails,
(B) medium snails and (C) small snails. Arenas each had 12 hills that varied in seedling
age at transplanting, the number of seedlings per hill, and the density at which the
seeds had been sown to seedbeds. Treatment categories indicate transplanting age and
hill-seedling number (i.e., 18-1 ¼ transplanted at 18 DAS at 1 seedling hill
1
). Standard
errors are indicated (N ¼ 5).
