Sažetak
Daphnia species are among the most common settlers of freshwater habitats. Due to their high sensitivity to various toxicants, these planktonic crustaceans represent a useful model organism in ecotoxicological research. Recently, Daphnia behaviour has gained attention and has been recognized as a sensitive biomarker of toxicity of sublethal concentrations of pollutants. The aim of this study was to investigate the effects of sublethal concentrations of three triazole fungicides (tebuconazole, difenoconazole and fenbuconazole) on swimming activity (average speed, mobility index, number of direction changes, discontinuity of motion etc.) and physiological parameters (heart rate, thoracic limb activity, movement of post-abdominal claw and movement of second antennae) of Daphnia magna. The study showed that the applied toxicants caused a decrease in swimming activity in a dose-response manner and also affected the physiological activity of the organisms. The results revealed that the investigated behavioural and physiological endpoints can be used as early biomarkers of exposure to environmentally relevant sublethal concentrations of commonly used commercial triazole fungicides.
