Abstract/OtherAbstract:
This paper compares the fate and effects of linuron in an outdoor plankton-dominated microcosm study carried out in Thailand with those reported in temperate model ecosystem studies evaluating linuron and other photosynthesis-inhibiting herbicides. Lower linuron concentrations disappeared slightly faster from the water compartment compared to temperate conditions, which appears to be related with the experimental design rather than differences in climatic conditions. Sensitivity of primary producers and zooplankton were similar for the climatic regions, whereas effects on ecosystem functioning were less pronounced in tropical microcosms. Recovery potential of affected endpoints appears higher for tropical ecosystems compared to their temperate counterparts. These findings support the use of toxicity data generated in temperate countries in the tropics. Recommendations for the methodology of tropical model ecosystem experiments are discussed.
