Indirect Effects of Sunflower Stars on Red Urchin Grazing from Controlled Experiments

Experimental data from two manipulative studies on marine predator-prey interactions. The dataset includes measurements of kelp blade weight before and after trials where predator activity and prey hunger state were varied. Author Nikita Sridhar published the data on figshare under a CC-BY-4.0 license, with a last update recorded in 2026.

Use Cases

• Modeling indirect predator effects on grazing pressure based on manipulated activity levels.
• Analyzing the impact of prey hunger state (from kelp forest vs. urchin barren) on consumption rates.
• Investigating kelp loss as a response variable under different experimental conditions.

Strengths

• Data is derived from two controlled experiments with manipulated variables (predator activity and prey hunger).
• Includes direct measurements of kelp blade weight as a primary response variable.
• Published under a permissive CC-BY-4.0 license, facilitating reuse.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small in scale at 839.9 KB, indicating limited scope.
