The taxonomic and ecological-floristic characteristics of the phytoplankton of a technogenic reservoir after the cessation of industrial exploitation by the example of Lake Shlamonakopitelnoe (Samara Region, Russia)

Abstract

The plankton algae species composition in the technogenic reservoir and the changes observed after the cessation of industrial exploitation have been studied using Lake Shlamonakopitelnoe as an example (Vasilievskie Ozera lake system, Samara Region, Russia). Comparison of the species composition and taxonomic structure of phytoplankton during the period of active industrial exploitation (1991–1992) and the post-exploitation period (2001) revealed an increase in the algae species richness and an increased complexity of the taxonomic structure. Therefore, this was the positive transformation of the phytoplankton community. The high species specificity of algoflora and the low level of species continuity in each study period indicated a significant degree of ecosystem transformation against the background of cessation of exploitation.
