title: The effect of seasonality and body size on the sensitivity of marine amphipods to toxicants.
abstract: Two factors, seasonality and body size, were studied to determine their influence on the sensitivity of the amphipods Corophium urdaibaiense and Corophium multisetosum to toxicants. Seasonality was studied by comparing LC50 values for cadmium and ammonia toxicity to both species over a year. Body size effect was studied by comparing LC50 values of ammonia in three size categories of C. urdaibaiense. Except for the case of C. urdaibaiense with ammonia as a toxicant, the sensitivity was maximum during summer and minimum during winter. Furthermore, differences in sensitivities were found among the three body size groups studied.
