Genetic Diversity of Eastern Tropical Pacific Spotted Eagle Rays

Aetobatus laticeps, the Eastern Tropical Pacific Spotted Eagle Ray, is an understudied species with low fecundity and high susceptibility to fisheries. This 5.5 KB dataset contains global and pairwise fixation indexes derived from a mixed genetic marker approach to assess phylogeny and phylogeography. The data, authored by Mateo Vinueza Guarderas and last updated in May 2026, suggests low genetic variability and high geographic-genetic structure, informing conservation status.

Use Cases

• Assessing population structure and genetic connectivity based on fixation indexes.
• Modeling potential isolation mechanisms (distance, philopatry, depth) mentioned in the study.
• Informing conservation status re-evaluation based on described low genetic variability and high structure.
• Comparative phylogeographic analysis of the Aetobatus genus in the Eastern Tropical Pacific region.

Strengths

• Data is openly licensed under CC-BY-4.0.
• Focuses on a recently re-described and understudied species, Aetobatus laticeps.
• Applies a mixed genetic marker approach as described in the study.

Limitations

• Dataset is very small at 5.5 KB, indicating limited scope.
• Row count and column-level documentation are unknown; field semantics must be inferred after download.
• The description suggests sampling was geographically unbalanced, with only 5 individuals from the study region.
