Dry-season precipitation reshapes functional gene composition and modulates ecosystem functioning in the tropical eutrophic Mirongo river

Key Points

• Altered precipitation significantly reshapes functional gene composition in the ecosystem.
• Ecosystem functioning appears to be closely linked to changes in dry-season precipitation levels.
• Analysis indicates that a shift in precipitation affects nutrient cycling and biodiversity metrics.
• Implications suggest a need for understanding moisture impacts on eutrophic river systems.
