Sažetak
Amphibians, as the most threatened group of vertebrates, are very susceptible to various environmental influences. One of the factors surrounding them is the water quality and its pollution. Although some areas in Europe have intensive agriculture, the influence of various pesticides on amphibians is still very poorly studied in general, especially in Europe. In our research, we examined the influence of three widely used pesticides dimethoate, pirimiphos-methyl and glyphosate on the development dynamic of eggs of agile frog, Rana dalmatina. Influence of each pesticide was examined in five different concentrations, namely the lowest was ten times lower than environmentally relevant, second was environmentally relevant, third was ten times higher, fourth was 100 times and fifth was 1000 times higher than environmentally relevant. Experiment was carried out on 30 eggs in each of three replicates. We measured time needed to hatching and the hatching rate/mortality. In the highest two concentrations of all three pesticides, the eggs did not develop into tadpoles, while in the concentration ten times higher than the environmentally relevant, the hatching rate was significantly lower in glyphosate then in other two pesticides. The lowest two concentrations of all three pesticides did not show to effect the development of eggs.
