Abstract (EN): The toxic effects of lindane on the zooplankton communities may be strongly related to the population fitness, which is highly dependent on food availability. In order to test this hypothesis, acute (immobilisation) and chronic (life-history) responses of Daphnia longispina and Daphnia magna, reared at different food levels (low, normal, and high), were assessed in laboratorial exposures to several concentrations of lindane. A bifactorial design was employed (food level versus lindane concentration) for both species. Results showed that lindane was toxic to both D. magna and D. longispina, within a similar range. However, lindane toxicity to daphnids was dependent on food level, suggesting that the latter is an important factor to take into account when assessing the toxic effects of lindane on zooplankton communities.
