Male Guppy Color Patterns Across Six Trinidad Sites and Years

Six years of male guppy color pattern data from six sites in Trinidad provide a direct measure of adaptive trait variation. The dataset, authored by Kiyoko M. Gotanda, examines spatiotemporal consistency in genetically-based color traits linked to predation regimes. It offers a complementary approach to traditional selection coefficient analysis for evolutionary studies.

Use Cases

• Analyze spatial variation in guppy color patterns across six Trinidad sites to correlate with known predation regimes.
• Assess temporal consistency of color traits by comparing data collected over six years at each site.
• Examine the interaction between spatial and temporal factors in phenotypic variation for Poecilia reticulata.
• Use site and year identifiers to model the relative importance of spatial versus temporal variation in adaptive traits.

Strengths

• Data spans six distinct geographic sites and six annual time points, enabling spatiotemporal analysis.
• Focuses on genetically-based adaptive traits (color patterns) with established links to selection pressures.
• Published under a permissive CC0 1.0 license, allowing for unrestricted reuse and analysis.

Limitations

• The sample size (number of individual guppy observations or rows) is not specified in the provided metadata.
• Geographic scope is limited to six specific sites in Trinidad, which may limit generalizability.
• The dataset's structure, specific measured color variables, and file formats are unknown.
