Abstract:
This article describes the peculiarities of the structural organization of zooplankton influenced by the waste products of
the black-headed gull (Larus ridibundus Linnaeus) nesting colony in the protected overgrown shallow in Rybinsk Reservoir. The bird colony facilitates a modification
of the zooplankton structure that is similar to the modifications of communities at early stages of eutrophication: the number
of invertebrate species increases thanks to rotifers and cladocerans and the number and biomass of community increases due
to cladocerans and copepods.
