DNA barcode dataset for “Globally dominant insect clades challenge canonical latitudinal diversity gradients and show contrasting climatic sensitivities”

Overview

This archive contains the curated DNA barcode dataset used in the manuscript “Globally dominant insect clades challenge canonical latitudinal diversity gradients and show contrasting climatic sensitivities” by Santos, Srivathsan, Neves, and Meier.

The dataset consists of COI DNA barcode records derived from public records in the Barcode of Life Data System (BOLD) and from previously published Malaise-trap studies. The analyzed dataset includes 101 Malaise-trap samples from 45 sites in 27 countries across six continents. These samples were used to quantify family-level dominance, latitudinal diversity gradients, spatial turnover, and climatic predictors of species richness in the ten most diverse flying-insect families recovered from the samples.

This archive is intended to provide a stable, reproducible snapshot of the exact sequence dataset and associated metadata used for the analyses. The original DNA barcode records remain attributable to their source datasets and publications; this repository provides the filtered, renamed, organized, and analysis-ready version used in the manuscript.

Data origin and provenance

The DNA barcode sequences were obtained from public BOLD records and previously published studies, as detailed in Supplementary Material S1 of the manuscript. All but three datasets were retrieved from published studies; the remaining three were obtained from the BOLD workbench under the public campaigns folder “Global Malaise Program.” Taxonomic assignments from BOLD and from the source publications were retained without modification.

Sequence names in the FASTA files were edited for consistency and traceability. Where available, sequence identifiers preserve information linking each record to its original dataset, trap, site, and/or BOLD record. Users interested in the original specimen records, trace files, images, collection metadata, or taxonomic assignments should consult the original BOLD records and source publications.
