In the Baltic Sea, a key species for monitoring is the brown seaweed Fucus vesiculosus, which forms sublittoral 3D habitats providing shelter and food for fish and invertebrates. Ecological distribution models predict a significant loss of Baltic F. vesiculosus due to ocean warming, unless populations can adapt. Genetic variation and recombination during sexual reproduction are essential for adaptation, but studies have revealed large-scale clonal reproduction within the Baltic Sea. We analysed genome-wide single nucleotide polymorphism (SNP) data from the east Atlantic, the \"Transition zone,\" and the Baltic Sea, and found a mosaic of divergent lineages in the Baltic Sea, contrasting an outside dominance of a few genetic groups. We determined that the previously described endemic species Fucus radicans is predominantly a large female clone of F. vesiculosus in its northern Baltic distribution. In the two Estonian sites, however, individuals earlier referred to as F. radicans are sexually and reproductively isolated from Baltic F. vesiculosus, revealing a separate lineage that may have diverged long before the formation of the Baltic Sea. Monitoring Baltic Fucus without considering this genetic complexity will fail to prioritise populations with adaptive potential to new climate conditions. From our genomic data, we can extract informative and diagnostic genetic markers that differentiate major genetic entities. Such a SNP panel will provide a straightforward tool for spatial and temporal monitoring and informing management decisions and actions.", "doi": "10.1111/mec.17699", "pmid": "39957665", "labels": {"National Genomics Infrastructure": "Service", "NGI Short read": "Service", "NGI Uppsala (SNP&SEQ Technology Platform)": "Service"}, "xrefs": [], "notes": [], "created": "2025-11-07T07:26:56.214Z", "modified": "2025-11-07T07:26:56.376Z"}, {"entity": "publication", "iuid": "9b508c1fd9064736b2a6e61b2a90718a", "links": {"self": {"href": "https://publications.scilifelab.se/publication/9b508c1fd9064736b2a6e61b2a90718a.json"}, "display": {"href": "https://publications.scilifelab.se/publication/9b508c1fd9064736b2a6e61b2a90718a"}}, "title": "Unlocking the secret life of blue mussels: Exploring connectivity in the Skagerrak through biophysical modeling and population genomics.", "authors": [{"family": "Gustafsson", "given": "Malin", "initials": "M"}, {"family": "Strand", "given": "\u00c5sa", "initials": "\u00c5", "orcid": "0000-0002-9029-4123", "researcher": {"href": "https://publications.scilifelab.se/researcher/9702edaf28fe4a56b9d345f0045d6165.json"}}, {"family": "Laugen", "given": "Ane T", "initials": "AT", "orcid": "0000-0001-6196-8304", "researcher": {"href": "https://publications.scilifelab.se/researcher/ed598dee082844f8b057abe7c4902ab3.json"}}, {"family": "Albretsen", "given": "Jon", "initials": "J", "orcid": "0000-0001-5863-2439", "researcher": {"href": "https://publications.scilifelab.se/researcher/fc5786b0b2f64052a1288038dc5a6310.json"}}, {"family": "Andr\u00e9", "given": "Carl", "initials": "C", "orcid": "0000-0003-4404-7292", "researcher": {"href": "https://publications.scilifelab.se/researcher/66e1d059567644a7b7080eb10d209723.json"}}, {"family": "Brostr\u00f6m", "given": "G\u00f6ran", "initials": "G"}, {"family": "Jorde", "given": "Per Erik", "initials": "PE", "orcid": "0000-0001-5515-7257", "researcher": {"href": "https://publications.scilifelab.se/researcher/0466e9d7fdff40718e81e9bd530510f9.json"}}, {"family": "Knutsen", "given": "Halvor", "initials": "H", "orcid": "0000-0002-7627-7634", "researcher": {"href": "https://publications.scilifelab.se/researcher/a822f994fed046018a713105bc5e03a0.json"}}, {"family": "Ortega-Martinez", "given": "Olga", "initials": "O", "orcid": "0000-0003-2734-6434", "researcher": {"href": "https://publications.scilifelab.se/researcher/bc84f54ca2cc49bc869cd23adeffc7ac.json"}}, {"family": "Sodeland", "given": "Marte", "initials": "M", "orcid": "0000-0001-6703-3972", "researcher": {"href": "https://publications.scilifelab.se/researcher/577d007c219b48f3919ca2d62c3303d3.json"}}, {"family": "Waern", "given": "Malin", "initials": "M", "orcid": "0000-0002-2459-040X", "researcher": {"href": "https://publications.scilifelab.se/researcher/15f48c8e09ab4b0880b4ed44feacbd87.json"}}, {"family": "Wrange", "given": "Anna-Lisa", "initials": "AL", "orcid": "0000-0002-3574-1779", "researcher": {"href": "https://publications.scilifelab.se/researcher/359e203f84144c26878b1dcbf1657dda.json"}}, {"family": "De Wit", "given": "Pierre", "initials": "P", "orcid": "0000-0003-4709-3438", "researcher": {"href": "https://publications.scilifelab.se/researcher/95b69d4724ce4b69819c0a1578cd56eb.json"}}], "type": "journal article", "published": "2024-05-00", "journal": {"title": "Evol Appl", "issn": "1752-4571", "volume": "17", "issue": "5", "pages": "e13704", "issn-l": "1752-4571"}, "abstract": "Knowledge of functional dispersal barriers in the marine environment can be used to inform a wide variety of management actions, such as marine spatial planning, restoration efforts, fisheries regulations, and invasive species management. Locations and causes of dispersal barriers can be studied through various methods, including movement tracking, biophysical modeling, demographic models, and genetics. Combining methods illustrating potential dispersal, such as biophysical modeling, with realized dispersal through, e.g., genetic connectivity estimates, provides particularly useful information for teasing apart potential causes of observed barriers. In this study, we focus on blue mussels (Mytilus edulis) in the Skagerrak-a marginal sea connected to the North Sea in Northern Europe-and combine biophysical models of larval dispersal with genomic data to infer locations and causes of dispersal barriers in the area. Results from both methods agree; patterns of ocean currents are a major structuring factor in the area. We find a complex pattern of source-sink dynamics with several dispersal barriers and show that some areas can be isolated despite an overall high dispersal capability. Finally, we translate our finding into management advice that can be used to sustainably manage this ecologically and economically important species in the future.", "doi": "10.1111/eva.13704", "pmid": "38770102", "labels": {"NGI Uppsala (SNP&SEQ Technology Platform)": "Service", "NGI Short read": "Service", "National Genomics Infrastructure": "Service", "Bioinformatics Support for Computational Resources": "Service"}, "xrefs": [{"db": "pmc", "key": "PMC11104481"}, {"db": "pii", "key": "EVA13704"}], "notes": [], "created": "2024-10-21T11:15:54.793Z", "modified": "2024-11-25T10:26:53.880Z"}]}
