Survival strategies of phytoplankton functional groups to environmental factors in a drinking water reservoir, central China
In this study, use survival strategies of phytoplankton functional groups to environmental factors in a drinking water reservoir. Survival strategies of phytoplankton in drinking water reservoirs were rarely analysed. Dynamics and survival strategies of phytoplankton community in Zhushuqiao Reservoir (Changsha, China) were studied bimonthly from April 2016 to February 2017 to fill this gap. In spring, species of CRS-strategy that adapted to low water temperature, light, and nutrient dominated. There were small individuals of opportunistic colonists of C-strategy observed before stratification. With the increase of nutrient and water temperature in summer, slightly bigger, disturbance-tolerant species of R-strategy and species of CS-strategy that adapted to stratification dominated. In winter, some species adapted to low water temperature, which were R-strategists. Key factors driven seasonal phytoplankton succession were water temperature, total phosphorus, and dissolved inorganic nitrogen. Attention should be paid to potential threats from algal bloom species with C-strategy, and future longer-term monitoring of the system and its surrounding watersheds is greatly needed.
期刊介绍:
Annales de Limnologie - International Journal of Limnology publishes papers on the ecology of freshwater systems, ranging from studies of aquatic organisms, physical and chemical works which relate to the biological environment, to ecological applications and frameworks for water management directives.
Main topics: Ecology of freshwater systems ; biodiversity, taxonomy, distribution patterns in space and time, biology of animals and plants ; experimental and conceptual studies which integrate laboratory and/or field work on physiology, population dynamics, biogeochemistry and nutrient dynamics, management, mathematical modelling ; techniques for sampling and chemical analyses, ecological applications, procedures which provide frameworks for environmental legislation.
