The typology of temporary waterbodies and the influence of their parameters on the crustacean species composition of zooplankton

The typology of temporary waterbodies in Saratov oblast has developed with a similarity in the composition of zooplankton species that serve as its foundation. Seven waterbody groups have been distinguished: waterbodies of flood lands, river valley terraces, steppe watersheds, brackish lagoons, brackish lagoons connected to irrigation networks, excavated ponds, and puddles. The specificity of zooplankton species composition in different types of temporary waterbodies is shown. A significant influence of waterbody lifetime on the number of zooplankton species has been revealed, with the waterbody capacity and surface area in the period of maximal water level also being of great importance.
