Counts of snails with encysted forms based on number of light exposures.

Values expressed as counts (%).
Each exposure group was composed of a total of 150 snails from 5 months of collection (n=30 snails/exposure/month).
Number of light exposures represents the number of times a given batch of snails received a 6-hour light exposure with an average ~1000 lux light intensity.
Values with the same letter are not significantly different from each other (p>0.001). Values with different letters are significantly different from each other (p<0.001).
