Hudsonian Godwit Genetic Data for Population Structure Analysis

Data and scripts from the manuscript "Lack of population structure of an extreme migratory shorebird: evidence of gene flow between geographically disparate populations" by Gherardi-Fuentes et al. 2026. The dataset includes nuclear microsatellite data from Hudsonian Godwits (Limosa haemastica) across two North American breeding and two South American nonbreeding areas. It is hosted on figshare under a CC-BY-4.0 license and was last updated on March 17, 2026.

Use Cases

• Conducting Discriminant Analysis of Principal Components (DAPC) based on the provided R script and .str file.
• Performing population structure analysis using the provided data in STRUCTURE and Arlequin formats.
• Assessing genetic differentiation and gene flow between geographically distinct breeding populations.
• Investigating the role of immature bird behavior in population mixing, as suggested in the manuscript's abstract.

Strengths

• Data is directly linked to a peer-reviewed publication in Ecology and Evolution (2026, e72771).
• Data is provided in multiple standard genetics software formats (Genealex, PowerMarker, Arlequin, STRUCTURE).
• Includes analysis scripts (R) and software settings files, facilitating reproducibility.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (70.2 KB), indicating a limited scope in terms of raw data volume.
