Overview

Investigates phytoplankton responses to environmental factors in cascade reservoirs, indicating key implications for management.

Key Points

  • The aim is to understand how phytoplankton communities respond to environmental changes in cascade reservoirs.
  • Investigated four cascade reservoirs in the lower Jinsha River during summer and winter 2023
  • Measured environmental factors including temperature, dissolved oxygen, and nutrient concentrations
  • Assessed phytoplankton density and community structure
  • Conducted statistical analyses including PERMANOVA and Mantel tests
  • Phytoplankton density decreased with depth; community structure varied significantly among reservoirs
  • Significant increase in Cyanophyta density from June to December (p < 0.05)
  • Higher concentrations of TN, NO3-N, DTN, and TP observed in December
  • Seasonal shifts identified: temperature and dissolved oxygen were key in June; nitrate nitrogen and suspended solids dominated in December
