Does foraging activity change with ontogeny? An assessment for six sympatric species of postmetamorphic litter anurans in central Amazonia
We studied the foraging activities of six frog species in their natural habitat, the leaf litter of tropical rain forest in central Amazonia. To describe intraspecific ontogenetic change in general activity during foraging, we used four indices of general activity (movement frequency, velocity when...
