New Caledonian Flightless Weevil Phylogenetic and Biogeographic Data

Data from a study on the transoceanic origin of microendemic and flightless New Caledonian weevils. The research uses a multimarker molecular phylogeny to infer two independent clades of Trigonopterus species in the archipelago. Dating estimates suggest a Late Miocene origin for both clades, supporting colonization from New Guinea.

Use Cases

• Infer ancestral ranges for Trigonopterus weevil lineages using biogeographical calibration data.
• Analyze evolutionary trajectories of foliage-dwelling versus leaf-litter inhabiting weevil clades.
• Study long-distance dispersal patterns in flightless beetles using molecular phylogeny data.
• Perform divergence dating to estimate Late Miocene origins of New Caledonian weevil lineages.

Strengths

• Data underpins a peer-reviewed study on a heated biogeographical debate.
• Includes molecular phylogeny data for analyzing two independent weevil clades.
• Provides dating estimates for colonization events in the Miocene epoch.

Limitations

• Sample data and specific file formats are unavailable for inspection.
• The dataset scope is focused on a specific genus (Trigonopterus) and region.
• Data structure (rows, columns) is not described, limiting immediate analytical use.
