The result of this study for the negative correlation between
the relative abundance of B.s. goniomphalos and of F.m. martensi
snails (r =−0.46, P < 0.001) supported the findings from Haruay
et al.(2008) that B.s. goniomphalos snail populations could be
in fluenced by species in teractions with F.m. martensi. Where F.m.
martensi were more abundant,lower B.s goniomphalos populations
were observed
