| Sumario: | The analysis of the changes of the general species composition of phytoplankton and of the complex of dominant algae species has been performed for a small urbanized water body under the influence of anthropogenic load by the example of the Lake Vos’merka (Togliatti city, Samara Oblast, Russia) from 1991 through 2015. The species composition of the algae of the lake was characterized as green algae-diatom-cyanobacteria and was taxonomically stable over the study period. Low intra-rank saturation degree and a small percentage of polytypic genera indicated harsh conditions in the studied ecosystem. The species composition of the complex of dominant algae species has changed significantly. By 2013, anthropogenic transformation promoted the transition of the Lake Vos’merka to the Planktothrix-type and developing there the Oscillatoria-induced disease. |
