Some singularities of distribution of zooplankton species-colonizers in littoral biotopes (macrophyte thickets, pebbly foreshore) of Saratov reservoir

The list of zooplankton species-colonizers of the Saratov reservoir registered in macrophyte thickets is given. Comparative analysis of development of species-colonizers and indigenous species of the zooplankton in biotopes with different highest aquatic vegetation and without it on a pebbly foreshore is made. It is determined that in the macrophyte communities representatives of boreal-Arctic complex of zooplankton species dominate. Zooplankton invasion species develop more greatly in communities of Potamageton natans and Elodea canadiensis.
