Alien Algae Species Invasions in Humic Rivers within Weakly Human Impact Basin by Pavel Kulizin, Ekaterina Vodeneeva, Nikita Martynenko, Ekaterina Sharagina, Alexander Okhapkin

“…The expansion of alien representatives of microphytobenthos was noted in the Volga River basin for the first time. For <i>Gonyostomum semen</i>, its European origin was revealed, for plankton and benthic diatom—Ponto-Caspian. …”

The Species Structure of Plankton Communities as a Response to Changes in the Trophic Gradient of the Mouth Areas of Large Tributaries to a Lowland Reservoir by Vyacheslav Zhikharev, Ekaterina Vodeneeva, Ivan Kudrin, Dmitry Gavrilko, Natalia Startseva, Pavel Kulizin, Oxana Erina, Maria Tereshina, Alexander Okhapkin, Galina Shurganova

“…The aim of this research was to identify the possible response of the diversity indicators of phyto- and zooplankton communities to trophic gradients in the mouth area of two large tributaries of the reservoir, formed in the Middle Volga River (Russia). Both linear regression models and canonical correlation analysis (CCA) were used to assess the role of abiotic and biotic predictors in the structural organization of plankton communities and to assess the changes in the parameters of the species plankton community structure in the trophic gradient. …”
