Small water bodies are very diversified environmentally, and also characterized by a considerable variation range of environmental parameters. these two features are responsible for the fact that the fauna of water mites is characterized by a considerable species diversity and that eurytopic species are prevalent. Due to the eurytopic character of the species it is very difficult to define the rules governing their environmental distribution, which probably often has a local character. The present study is an attempt at analyzing this problem, focusing on water mite fauna of kettle holes in Rostock surroundings (Germany). The main factor diversifying the fauna of studied reservoirs is their trophism. Correspondence analysis distinguished three separate groups among the reservoirs. the isolation of the reservoirs was an important factor diversifying the water mite fauna.

This study analyses the composition, species richness and diversity (H’) of aquatic molluscan communities in temporary water bodies within the valley of the lower Bug River in eastern Poland. The investigations were carried out in 2007–2009 within the section of the valley located between 190th and 50th km of the river course in 50 water bodies. Relatively rich and diverse malacofauna was found in the investigated habitats: 32 snail species and 6 bivalve species. Species diversity (H’) in individual water bodies ranged from 0.44 to 3.48. About 40% of all mollusc species showed frequencies of _10%. Dominance patterns varied much among the water bodies. Mollusc abundance ranged from 20 to over 1,800 indiv./m2. Considerable species richness and diversity were found both within the active floodplain and the former one. This was probably related to the long duration of many of the investigated water bodies, as well as their periodical hydrological connectivity with permanent ones or river channel. From 9 to 12 samples should be enough to compile representative species list of molluscs inhabiting temporary water bodies, but as many as 28–40 samples would be necessary to obtain complete dataset.
