Mangrove Killifish Behavioral and Epigenetic Data from Environmental Enrichment Study

1,854 differentially methylated cytosines were identified in the brains of parent fish. The dataset compares neophobia, metabolic rate, and brain DNA methylation patterns in genetically identical mangrove killifish reared in enriched or barren environments. It was produced by Waldir Berbel Filho at Swansea University.

Use Cases

• Analyzing the relationship between environmental enrichment and cortisol levels based on physiological measurements
• Investigating intergenerational transmission of behavioral traits like neophobia based on parental environment
• Identifying specific DNA methylation sites influenced by parental environment based on the 98 DMCs shared with offspring
• Studying the link between metabolic rate and epigenetic state in a controlled genetic background

Strengths

• Data is from a self-fertilizing, inbred fish model, providing a controlled genetic background
• Measures multiple modalities: behavior (neophobia, activity), physiology (cortisol, metabolic rate), and molecular biology (DNA methylation)
• Identifies 1,854 differentially methylated cytosines in parents and 98 with patterns shared in offspring

Limitations

• Row count and specific column-level documentation are unknown; data structure must be inferred
• Last update date is unknown; freshness unverified
• Data may reflect the specific biology of the mangrove killifish model, limiting generalizability
