Phytoplankton: Seasonal Shifts and Their Role in Lake Ecosystems
Introduction:
An introduction to the topic “Phytoplankton: Seasonal Shifts and Their Role in Lake Ecosystems”, Phytoplankton are the foundation of aquatic food chains, playing a central role in energy transfer, oxygen production, and water quality. These microscopic, autotrophic organisms respond quickly to environmental changes, making them sensitive indicators of ecological health.
Seasonal fluctuations in temperature, nutrients, and light availability influence their density, diversity, and community composition. This blog explores how different classes of phytoplankton dominate in various water conditions, drawing on studies across India and beyond.
Understanding their seasonal behavior is vital for managing freshwater resources and conserving wetlands like Bichnaiyya Lake.

Phytoplankton are microscopic, free-living, free-floating autotrophic organism and play a vital role in the aquatic ecosystem as they help to provide energy for the ecosystem.
The first organisms in an aquatic habitat are phytoplankton. According to Pandey et al. (2004), phytoplankton is an important part of aquatic flora and helps to keep the biotic and abiotic elements of an aquatic environment in equilibrium.
The tiny, unicellular, floating, colonial, autotrophic organisms known as phytoplankton are found in aquatic environments, and water currents largely regulate their migration (Millman et al., 2005).
Phytoplankton showed considerable fluctuation with physicochemical parameters of water quality. Cyanophyceae and Chlorophyceae are dominant over Desmidiaceae and Euglenophyceae (Pawar and Sonawane, 2011).
Many researchers investigated phytoplankton from various regions of India. (Telkhade et al., 2008; Mishra et al., 2011; Sarwade and Kamble, 2014; Jitesh and Radhakrishnan, 2015).
According to Yu et al. (2012), Cao et al. (2018), Nankabirwa et al. (2019) and Zhang et al. (2020), studies on seasonal phytoplankton succession offer vital information about the dynamics of the ecosystem, including changes in biomass, cell density, species composition, and spatial distribution.
It has been established that phytoplankton serves as a key indicator of the way landscape usage affects the ecological integrity of lakes in urban areas (Kakoui et.al., 2021).
