Abstract
The effect of different ecological niches on growth and behaviour of larvae of four frogs (Bufo viridis, Hyla arborea, Pelobates syriacus, Rana ridibunda), and two salamanders (Salamandra salamandra and Triturus vittatus) found in a winter pond was studied. S. salamandra, T. vittatus, R. ridibunda and B. viridis were found most of the time on the bottom of the pond. However, H. arborea tadpoles were found throughout the pond and were usually sedentary, as compared with P. syriacus which moved up and down constantly. S. salamandra, T. vittatus, R. ridibunda and R viridis tadpoles from the bottom of the pond grew faster than the tadpoles from the surface of the pond. However, tadpoles of H. arborea and P. syriacus growing at the bottom or on the surface developed at similar rates. The invertebrate biomass increases during the summer and was higher at the bottom of the pond than at the surface. However the amount of chlorophyll a was about the same at the surface and at the bottom of the pond. S. salamandra and T. vittatus tadpoles feed on various types of of invertebrates, R. ridibunda and H. arborea and B. viridis tadpoles feed on vascular plants and algae, and P. syriacus tadpoles feed on both invertebrates and plants.
