Potamopyrgus Antipodarum Invasion Genetics Across Three Continents

1,617 samples of the gastropod Potamopyrgus antipodarum from native New Zealand and invasive North American and European populations were analyzed using multilocus nuclear SNP markers. The research by Carina Donne from the University of Iowa reconstructed the invasion routes of asexual lineages. The analysis suggests New Zealand as the source for European lineages, which subsequently contributed to North American invasions.

Use Cases

• Reconstructing invasion pathways based on genetic lineage relationships described in the study.
• Analyzing the population structure of invasive species using the multilocus SNP markers mentioned.
• Comparing genetic variation between native and invasive populations as detailed in the description.
• Modeling the spread of clonal lineages across continents as suggested by the findings.

Strengths

• Geographically broad sampling scheme includes 1,617 specimens.
• Analysis includes populations from three continents: New Zealand, Europe, and North America.
• Uses multilocus nuclear SNP markers for population genetic assessment.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
