Resumen:
Pesticide-induced effects in non-target organisms are a worldwide environmental problem and cladocerans have been used as test organisms to quantify the toxicity effects. However, little is known about the true risks of acceptable levels, when non-traditional end points such as sex determination, egg maturation, and teratogenesis are considered. Aims of the present study were to investigate the effects of sublethal concentrations of the fungicide carbendazim taking into account the above-mentioned endpoints and to evaluate their sensitivity to an environmental factor such as temperature, known to influence growth rates and sex determination in cladocerans. We quantified the effect on the life history variables of Moina micrura at two different temperatures using the life table demographic approach, starting with neonates. The median lethal concentration of carbendazim for M. micrura was 0.12 +/- A 0.01 mg l(-1). The impacts of carbendazim were assessed in experiments conducted at 20A d
