Aquatic Ecosystem Responses to Nutrient Perturbation in 16 Experimental Ponds

16 large (15,000L) experimental ponds were manipulated in a factorial design with two foundation species (macrophytes and mussels) and subjected to two periods of nutrient perturbation. Measurements were taken at high resolution (15-minute intervals) over two years, tracking ecosystem properties like phytoplankton density and metabolism. The dataset was created by Moritz L rig at the Swiss Federal Institute of Aquatic Science and Technology to study non-additive effects of species interactions on ecosystem recovery.

Use Cases

• Modeling non-additive antagonistic effects on algal biomass based on the presence of multiple foundation species.
• Analyzing high-resolution temporal dynamics of ecosystem metabolism following nutrient perturbations.
• Studying the persistence of clear water states in aquatic systems under different nutrient loading regimes.
• Investigating the individual and combined roles of macrophytes and mussels as ecosystem engineers.

Strengths

• High-resolution time-series data collected at 15-minute intervals.
• Factorial experimental design manipulating two foundation species across 16 large-scale ponds.
• Two-year study duration with two distinct periods of nutrient perturbation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
