New World Sparrow Phylogenetic Data for Latitudinal Diversity Gradient Analysis

Reinhard E Matadamas provides a 35.3 MB dataset supporting the manuscript 'Evolutionary time drives the inverse latitudinal diversity gradient of New World Sparrows (Aves: Passerellidae)'. The dataset includes components necessary to reproduce the analyses, such as phylogenetic trees and species distribution data, and was last updated on 2026-05-04. It is shared under a CC-BY-4.0 license on figshare.

Use Cases

• Reproducing phylogenetic comparative analyses based on the provided scripts and data.
• Testing hypotheses about the role of evolutionary time in shaping species diversity patterns.
• Conducting secondary analyses on New World sparrow biogeography and phylogeny.

Strengths

• Includes a comprehensive README file explaining the workflow for reproducibility.
• Dataset is 35.3 MB, suggesting it contains substantial supporting data for the analyses.
• Directly supports a peer-reviewed manuscript with a DOI (10.1098/RSPB.2026.0213).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic or taxonomic bias inherent to the source study.
