Long-term variations in plankton community structure and environmental drivers in Korean artificial lake

Abstract

With the intensification of global warming, the occurrence of harmful algal blooms (HABs) in freshwater ecosystems have become more prolonged and frequent. As phytoplankton and zooplankton are sensitive to changes in environmental conditions such as temperature, light intensity, and nutrients, understanding how environmental factors affect plankton community structure can help to predict the response of freshwater ecosystems to climate change. However, studies on the long-term monitoring of plankton community structure in Lake Soyang, an important source of drinking water for metropolitan areas in South Korea, and other domestic freshwater systems in Korea remain limited. Here, we investigated the changes in phytoplankton and zooplankton community composition in response to environmental factors in Lake Soyang during a long-term survey period. The results revealed that diatoms were negatively correlated (p
