The diverse tolerance capacities of submerged macrophytes to high urea-N concentrations

Key Points

• Submerged macrophytes exhibit varied tolerance capacities to elevated urea-N concentrations, influencing their survival.
• In high urea-N concentrations, certain macrophytes showed a tolerance threshold at 50 mg/L, highlighting their adaptive potential.
• Observational analysis across various aquatic ecosystems assessed the influence of nutrient uptake and tolerance mechanisms under stressed conditions.
• These findings may enable better management strategies for aquatic environments facing nutrient overloads and pollution.
