ResumoSpawn eating (predation and cannibalism) by tadpoles of sympatric Anurans. Tadpoles of 5 Anuran species were tested with spawn of 4 sympatric species or 3 sympatric and their own species respectively. All spawn offered was eaten. Spawn cannibalism as well as spawn predation amongst species which occur in ecological sympatry (e.g.Bufo calamita, Hyla arborea andBombina variegata may act as a density regulation mechanism.
