Hydra Vulgaris Egg Production Data from Starvation and Selection Trial

Data Sheet 2_Optimizing egg production by trait selection and starvation in Hydra vulgaris.zip contains experimental data on inducing gametogenesis in the freshwater cnidarian Hydra vulgaris. The dataset, authored by Kelso N. Cochran and last updated in April 2026, likely records results from a 4-week starvation trial comparing five replicate populations of a selected 'KSO' colony against a control 'AEP' group. The study demonstrated a 5-fold increase in egg production through combined trait selection and starvation.

Use Cases

• Analyzing the effect of trait selection on egg production bias based on the described KSO colony.
• Modeling the impact of starvation protocols on gametogenesis induction rates.
• Comparing sexual reproduction outcomes between selected and control populations over a 4-week trial.
• Validating methods for establishing stable egg-producing populations for transgenic research.

Strengths

• Dataset is based on a 4-week-long starvation trial with five replicate populations of 100 polyps each.
• The described experimental approach resulted in a documented 5-fold increase in egg production over the control.
• Data is shared under a permissive CC-BY-4.0 license.

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 (1.7 MB), which may constrain the scope of analysis.
