90 specimens of the gastropod Tegula funebralis from three distinct rocky intertidal populations near Bamfield, British Columbia, Canada. The dataset supports replication of analyses on aperture morphology variation along an environmental energy and predation gradient. It was authored by Nathaniel E.D. Morley and last updated in May 2026.
Use Cases
- Perform geometric morphometric analysis based on landmark and semi-landmark data.
- Investigate correlations between shell aperture shape and environmental gradients based on the described energy and predation pressures.
- Model potential morphological responses to increased storm frequency and predation pressure in a changing climate.
- Replicate statistical analyses and visualizations from the associated scientific manuscript.
Strengths
- Includes data for 90 individual specimens, enabling population-level comparisons.
- Focuses on three distinct populations along a documented environmental gradient, providing a controlled comparative framework.
- Contains code to replicate all analyses and figures from the original manuscript, supporting reproducibility.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
