Rebuilding a clear-water state dominated by submerged macrophytes is essential for addressing eutrophication, yet the impact of benthic fish on water quality is complex. We conducted two experiments to explore the interaction of submerged plants and benthic fish on the water quality. Experiment I investigated the water clearing effects of submerged macrophytes with varying coverage (from 0% to 40%) before and after the removal of benthic fish.

Article Synopsis
  • Different macrophyte growth forms affect water quality in lakes, with notable differences between areas with plants and open water.
  • A four-year study showed that ecological restoration projects significantly improved both plant communities and water quality by altering the types of macrophytes present.
  • The decline of canopy-forming plants and the rise of noncanopy plants enhanced water exchange, leading to more uniform water quality across different areas of the lake.

Submerged macrophytes can improve water quality and buffer the effects of external nutrient loading, which helps to maintain a clear-water state in shallow lakes. We constructed 12 large enclosures with contrasting coverages (treatments) of submerged macrophytes (SMC) to elucidate their buffering capacity and resilience to nutrient pulses. We found that aquatic ecosystems with high SMC had higher buffering capacity and resilience, vice versa, i.

Article Synopsis
  • Increasing eutrophication presents a significant threat to freshwater ecosystems, leading to a decline in submerged macrophytes, which are crucial for ecosystem health and human well-being.
  • The research conducted in 49 lakes and reservoirs in southwestern China demonstrates that submerged macrophyte biodiversity positively influences ecosystem functioning, where functional diversity is a stronger predictor of biomass than species richness.
  • The study highlights a shift in biodiversity-ecosystem functioning mechanisms under eutrophication from "niche complementarity" to "selection effects," indicating the need to protect environmental health to maintain biodiversity and associated ecological functions.
