Makrofauna bezkręgowa wód parku Pole Mokotowskie w Warszawie
Macroinvertebrates in water bodies in the Pole Mokotowskie park in Warsaw

Summary/Abstract: The study was carried out in small, shallow, artificial water bodies in the Pole Mokotowskie park in Warsaw. Rich and diversified invertebrate macrofauna were found (in summer up to almost 3,000 individuals per m2 and total of 22 taxa). Despite the short time of existence of these water bodies (about 50 years), extreme environmental conditions (long periods of drying, lack of bottom sediments and almost total lack of macrophytes) and isolation from other waters, there are numerous organisms that spend their entire life cycle in the water – snails, bivalves and crustaceans; less leeches. The fauna of insects was numerous, but not very diverse; the oligochaetes were few. Two species from the Red List of invertebrate animals in Poland – the leech Dina lineata and bivalve Musculium lacustre were found.
