The studied lakes differ in their origin, hydrological conditions, and also in the level of anthropogenic load. It has been found that changes in relationship between various groups of pigments correlate with changes in phytoplankton structure. The given pigment indices can be used in assessing the structure of algal communities, the physiological state of algae, their quantitative development, and the ecological state of water bodies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
