Paula Rodriguez Flores from Harvard Dataverse published genomic data for a time-calibrated phylogeny of deep-sea squat lobsters (family Eumunididae). The dataset includes over 60% of the known species diversity and was used to study diversification rates and the impact of the Isthmus of Panama closure. It was last updated on 2026-05-29.
Use Cases
- Reconstructing phylogenetic relationships among Eumunididae species based on Ultraconserved Element (UCE) data.
- Estimating ancestral geographic ranges and testing vicariance hypotheses related to the Isthmus of Panama.
- Analyzing lineage-specific diversification rates (speciation and extinction) using Bayesian macroevolutionary mixture models.
- Investigating cryptic species diversity and validating taxonomic subgenera within the family.
Strengths
- Includes genomic data (Ultraconserved Elements) for more than 60% of the known species in the family Eumunididae.
- Phylogeny is time-calibrated, enabling analysis of evolutionary timing and rates.
- Analysis integrates taxonomic sampling with models for ancestral range estimation (DEC+J) and diversification rates (BAMM).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for some analyses.
- Freshness should be verified as the last update date is in the future (2026-05-29).
