Long‐term changes to plankton communities in artificially heated lakes

open access: yesLimnology and Oceanography, Volume 70, Issue 10, Page 3029-3042, October 2025.
Abstract Increased surface‐water temperatures and nutrient enrichment are predicted to alter planktonic communities, impacting biodiversity and ecosystem functioning. While short‐term mesocosm studies have reported temperature‐ and nutrient‐driven effects, long‐term observations from natural systems remain limited.

Post-impoundment biomass and composition of phytoplankton in the Yangtze River [PDF]

open access: yes, 2007
Damming, and thus alteration of stream flow, promotes higher phytoplankton populations and encourages algal blooms (density > 10(6) cells L-1) in the Three Gorges Reservoir (TGR). Phytoplankton composition and biomass were studied in the Yangtze River
