--- res: bibo_abstract: - 'Chromosomal inversions have long been recognized for their role in local adaptation. By suppressing recombination in heterozygous individuals, they can maintain coadapted gene complexes and protect them from homogenizing effects of gene flow. However, to fully understand their importance for local adaptation we need to know their influence on phenotypes under divergent selection. For this, the marine snail Littorina saxatilis provides an ideal study system. Divergent ecotypes adapted to wave action and crab predation occur in close proximity on intertidal shores with gene flow between them. Here, we used F2 individuals obtained from crosses between the ecotypes to test for associations between genomic regions and traits distinguishing the Crab‐/Wave‐adapted ecotypes including size, shape, shell thickness, and behavior. We show that most of these traits are influenced by two previously detected inversion regions that are divergent between ecotypes. We thus gain a better understanding of one important underlying mechanism responsible for the rapid and repeated formation of ecotypes: divergent selection acting on inversions. We also found that some inversions contributed to more than one trait suggesting that they may contain several loci involved in adaptation, consistent with the hypothesis that suppression of recombination within inversions facilitates differentiation in the presence of gene flow.@eng' bibo_authorlist: - foaf_Person: foaf_givenName: Eva L. foaf_name: Koch, Eva L. foaf_surname: Koch - foaf_Person: foaf_givenName: Hernán E. foaf_name: Morales, Hernán E. foaf_surname: Morales - foaf_Person: foaf_givenName: Jenny foaf_name: Larsson, Jenny foaf_surname: Larsson - foaf_Person: foaf_givenName: Anja M foaf_name: Westram, Anja M foaf_surname: Westram foaf_workInfoHomepage: http://www.librecat.org/personId=3C147470-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0003-1050-4969 - foaf_Person: foaf_givenName: Rui foaf_name: Faria, Rui foaf_surname: Faria - foaf_Person: foaf_givenName: Alan R. foaf_name: Lemmon, Alan R. foaf_surname: Lemmon - foaf_Person: foaf_givenName: E.
