Cytochrome B Gene Mutation Patterns in Cypriniform Fish Across Climates and Body Sizes

Transition and transversion mutation frequencies in the mitochondrial CYTB gene for the order Cypriniformes, analyzed to test the metabolic theory of ecology. The dataset, created by Svyatoslav Morozov-Leonov and last updated in May 2026, compares small- and large-bodied fish lineages from tropical and temperate climatic zones. It provides evidence for a link between metabolic rate, body size, and molecular evolutionary rates.

Use Cases

• Testing the metabolic theory of ecology based on mutation type bias across taxonomic groups.
• Comparing molecular evolutionary rates between tropical and temperate fish lineages based on climatic affiliation data.
• Analyzing the relationship between body size and mutation accumulation based on size categories mentioned in the description.
• Investigating the evolutionary rate hypothesis using transversion frequency patterns in warm, stable environments.

Strengths

• Data supports a specific hypothesis (metabolic theory of ecology) with a clear methodological approach described.
• Analysis includes comparisons across two distinct variables: climatic zone and body size.
• Dataset is openly available under a CC-BY-4.0 license.

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 (264.9 KB), indicating limited scope.
