The use of samplers with artificial substrate will not only house colonizations by benthic organisms, but also by the periphyton, since the materials used in the sampler (cattail leaves, loofah, crushed stone and gravel) serve as a basis for the development of periphytic algae, which indirectly also benefits herbivorous animals.
