Species | Laminaria ochroleuca | |
Date of the first record (?) | 2018 References: Schoenrock, K. M., O’Callaghan, T., O’Callaghan, R., & Krueger-Hadfield, S. A. (2019). First record of Laminaria ochroleuca Bachelot de la Pylaie in Ireland in Béal an Mhuirthead, county Mayo. Marine Biodiversity Records, 12(1), 1-8. Comments: The first record of Laminaria ochroleuca in the Republic of Ireland, discovered during a citizen science marine habitat survey effort during September 2018 (inter- and subtidal) between National University of Ireland (NUI) Galway, Porcupine Marine Natural History Society (PMNHS), and SeasearchIreland in Béal an Mhuirthead, Co. |
Recipient region (?) | Country: Ireland LME: 24. Celtic-Biscay Shelf LME sub-region: Celtic seas References: Schoenrock, K. M., O’Callaghan, T., O’Callaghan, R., & Krueger-Hadfield, S. A. (2019). First record of Laminaria ochroleuca Bachelot de la Pylaie in Ireland in Béal an Mhuirthead, county Mayo. Marine Biodiversity Records, 12(1), 1-8. Comments: Surveys in kelp habitats took place around the coastline of Béal an Mhuirthead from 0 to 11m depth |

Source region (?) | Not entered |
Pathway / Vector (?) | Level of certainty: Highly likely Pathway: Vessels Vector: (Possible) Ballast water References: Schoenrock, K. M., O’Callaghan, T., O’Callaghan, R., & Krueger-Hadfield, S. A. (2019). First record of Laminaria ochroleuca Bachelot de la Pylaie in Ireland in Béal an Mhuirthead, county Mayo. Marine Biodiversity Records, 12(1), 1-8. Comments: Potential vectors for L. ochroleuca are few in the area, as Black Sod Pier is only open to small fishing vessels and recreational craft, but there is potential that the bay may offer refuge to larger vessels in bad weather conditions. |
Habitat type (?) | Sheltered coastal area References: Schoenrock, K. M., O’Callaghan, T., O’Callaghan, R., & Krueger-Hadfield, S. A. (2019). First record of Laminaria ochroleuca Bachelot de la Pylaie in Ireland in Béal an Mhuirthead, county Mayo. Marine Biodiversity Records, 12(1), 1-8. Comments: A small population of L. ochroleuca (~ 100 individuals counted) was discovered in a sheltered cove called Scots Port on the northwest facing coastline of Béal an Mhuirthead |

Population status (?) | Rare (single record) (Moderate level of certainty) References: Schoenrock, K. M., O’Callaghan, T., O’Callaghan, R., & Krueger-Hadfield, S. A. (2019). First record of Laminaria ochroleuca Bachelot de la Pylaie in Ireland in Béal an Mhuirthead, county Mayo. Marine Biodiversity Records, 12(1), 1-8. Comments: The only known Irish population - the small population of L. ochroleuca (~ 100 individuals counted) was discovered in a sheltered cove called Scots Port on the northwest facing coastline of Béal an Mhuirthead, September 10th, 2018. |

Species status (?) | Non-indigenous species References: Schoenrock, K. M., O’Callaghan, T., O’Callaghan, R., & Krueger-Hadfield, S. A. (2019). First record of Laminaria ochroleuca Bachelot de la Pylaie in Ireland in Béal an Mhuirthead, county Mayo. Marine Biodiversity Records, 12(1), 1-8. Comments: It’s remote location indicates there are likely more populations along the coastline, however the allelic richness and heterozygosity reflect that of Iberian populations within it’s distribution center. Estimates were more similar to sites sampled in the southern Iberian Peninsula, the Azores, and north western Africa despite strong differentiation from these populations |
