Variation in a few parameters can explain much of the diversity of shell shapes seen in nature. However, empirical studies of gastropod shell shape variation typically use geometric morphometric approaches, which do not capture this growth pattern. We have developed a way to infer a set of developmentally descriptive shape parameters based on three-dimensional logarithmic helicospiral growth and using landmarks from two-dimensional shell images as input. We demonstrate the utility of this approach, and compare it to the geometric morphometric approach, using a large set of Littorina saxatilis shells in which locally adapted populations differ in shape. Our method can be modified easily to make it applicable to a wide range of shell forms, which would allow for investigations of the similarities and differences between and within many different species of gastropods.","lang":"eng"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"file":[{"relation":"main_file","file_id":"7660","checksum":"4eb102304402f5c56432516b84df86d6","access_level":"open_access","content_type":"application/pdf","file_name":"2020_JournRoyalSociety_Larsson.pdf","creator":"dernst","file_size":1556190,"date_updated":"2020-07-14T12:48:01Z","date_created":"2020-04-14T12:31:16Z"}],"status":"public","publication":"Journal of The Royal Society Interface","volume":17,"has_accepted_license":"1","issue":"163","article_type":"original","oa":1,"publication_status":"published","month":"02","article_number":"20190721","intvolume":" 17","date_published":"2020-02-01T00:00:00Z","article_processing_charge":"No","doi":"10.1098/rsif.2019.0721","date_created":"2020-04-08T15:19:17Z","_id":"7651","publisher":"The Royal Society","publication_identifier":{"eissn":["1742-5662"],"issn":["1742-5689"]},"file_date_updated":"2020-07-14T12:48:01Z","year":"2020","date_updated":"2021-01-12T08:14:41Z","oa_version":"Published Version","quality_controlled":"1","scopus_import":1,"type":"journal_article","day":"01"}
