Marine snails of the genus Littorina repeatedly form hybrid zones between populations segregating for multiple inversion arrangements, providing opportunities to study their barrier effects. Here, we analyzed 2 adjacent transects across hybrid zones between 2 ecotypes of Littorina fabalis (\"large\" and \"dwarf\") adapted to different wave exposure conditions on a Swedish island. Applying whole-genome sequencing, we found 12 putative inversions on 9 of 17 chromosomes. Nine of the putative inversions reached near differential fixation between the 2 ecotypes, and all were in strong linkage disequilibrium. These inversions cover 20% of the genome and carry 93% of divergent single nucleotide polymorphisms (SNPs). Bimodal hybrid zones in both transects indicated that the 2 ecotypes of Littorina fabalis maintain their genetic and phenotypic integrity following contact. The bimodality reflects the strong coupling between inversion clines and the extension of the barrier effect across the whole genome. Demographic inference suggests that coupling arose during a period of allopatry and has been maintained for > 1,000 generations after secondary contact. Overall, this study shows that the coupling of multiple chromosomal inversions contributes to strong reproductive isolation. Notably, 2 of the putative inversions overlap with inverted genomic regions associated with ecotype differences in a closely related species (Littorina saxatilis), suggesting the same regions, with similar structural variants, repeatedly contribute to ecotype evolution in distinct species.", "doi": "10.1093/evlett/qrae014", "pmid": "39479507", "labels": {"Bioinformatics Support for Computational Resources": "Service"}, "xrefs": [{"db": "pmc", "key": "PMC11523631"}, {"db": "pii", "key": "qrae014"}], "notes": [], "created": "2024-11-25T10:23:07.835Z", "modified": "2025-02-28T14:17:31.399Z"}, {"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"}]}
