The mankind is still far from establishing harmonious relations with it. However, permanently progressing destruction of natural complexes by the technogenic civilization necessitates some new revolutionary approaches to their preservation. That is why it is so important to study the relationships and interactions between living organisms. One of the most important roles in this “orchestra” is played by numerous invertebrates which filter the water and improve water quality.
