First Iberian records of the alien amphipod Ericthonius didymus and additional records of Ianiropsis cf. serricaudis and Aoroides longimenus collected from the Spanish coast of the Bay of Biscay. Specimens were gathered from ports and natural rocky shores along the Asturian coast using standardized slate-tile deployments. The dataset was authored by Yaisel Juan Borrell Pichs and last updated on May 15, 2026.
Use Cases
- Tracking the spread of non-indigenous marine species based on new and additional species records.
- Studying the establishment of alien populations based on presence across multiple sites and sampling periods.
- Investigating introduction pathways for marine NIS based on occurrence in anthropized environments like ports.
- Validating species identification based on combined morphological examination and mitochondrial 16S rRNA analysis.
Strengths
- Includes first Iberian records for the alien amphipod Ericthonius didymus.
- Species identification was supported by both detailed morphological examination and mitochondrial 16S rRNA analyses.
- Data is licensed under CC-BY-4.0, permitting sharing and adaptation.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect geographic bias inherent to sampling along the Asturian coast.
