Hydra Vulgaris Egg Production Data from Starvation and Selection Trial

A 4-week-long starvation trial with five replicate populations of 100 Hydra vulgaris polyps each, conducted to validate a method for inducing egg production. The dataset, created by Kelso N. Cochran and last updated in April 2026, provides evidence that trait selection and starvation resulted in a 5-fold increase in egg production over the control group. The study aims to advance transgenic methodology in this model organism.

Use Cases

• Modeling the effect of starvation on gametogenesis based on the described experimental protocol.
• Analyzing population-level sexual bias toward egg production based on the reported significant evidence.
• Comparing reproductive trait selection outcomes between the KSO and AEP control groups described in the study.

Strengths

• Data is from a controlled 4-week experiment with five replicate populations of 100 polyps each.
• Results show a 5-fold increase in egg production over the control, providing a clear quantitative outcome.
• Dataset is licensed under CC-BY-4.0, permitting reuse with attribution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a 1.8 MB PDF, which may require extraction of underlying data.
