Primary Producers: Freshwater Mesocosm Experiment on Warming, Pollution, and Food Webs

A 10-month mesocosm experiment simulating the combined effects of warming, surface runoff pollution, and food web simplification on freshwater ecosystems. The dataset contains results from 48 experimental units, each of 2500 liters, and was authored by Chenghao Du. It was last updated on May 23, 2026.

Use Cases

• Modeling the individual and combined effects of warming, pollution, and food web simplification based on the described experimental design.
• Analyzing ecosystem resilience to pulsed surface runoff pollution based on the mesocosm setup.
• Studying the impact of a +2°C temperature increase on primary producer dynamics in freshwater environments.

Strengths

• Experimental design includes 48 large-scale mesocosm units of 2500 liters each.
• Explicitly tests three co-occurring stressors (warming, pollution, food web simplification) over a 10-month period.
• Dataset is openly licensed under CC-BY-4.0.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small in size (236 KB), suggesting limited scope or aggregated summary data.
