Abstract
Parthenogenesis is common among invasive pest species, with many parthenogenetic species also showing polyploidy. Parthenogenetic polyploid species often have multiple hybrid origins and the potential to rapidly spread over vast geographical areas. In this study, we examine patterns of mitochondrial and microsatellite variation in a widespread triploid parthenogenetic chironomid pest species, Paratanytarsus grimmii. Based on samples from five countries, including Australia, England, Germany, Japan, and Canada, we found extremely low mitochondrial diversity (<0.14%), with most individuals sharing a common and widespread haplotype. In contrast, microsatellite diversity revealed 41 clonal variants, which were regionally endemic. These findings suggest a single invasive maternal lineage of P. grimmii is likely to have recently spread over a broad geographical range. High levels of genotypic endemism suggest P. grimmii populations have remained relatively isolated after an initial spread, with little ongoing migration. This, in part, can be attributed to rapid genetic differentiation via mutations of common clonal genotypes after P. grimmii spread, but multiple polyploidization and subsequent founder events are also likely to be contributing factors.

These findings suggest a single invasive maternal lineage of P. grimmii is likely to have recently spread over a broad geographical range. High levels of genotypic endemism suggest P. grimmii populations have remained relatively isolated after an initial spread, with little ongoing migration. This, in part, can be attributed to rapid genetic differentiation via mutations of common clonal genotypes after P. grimmii spread, but multiple polyploidization and subsequent founder events are also likely to be contributing factors.</abstract><note type="additional physical form">Appendix S1</note><note type="funding">Australian Research Council</note><note type="funding">Melbourne Water Corporation</note><note type="funding">Victorian Government</note><note type="funding">EPA Victoria</note><subject><genre>keywords</genre><topic>invasive</topic><topic>microsatellites</topic><topic>mitochondrial</topic><topic>Paratanytarsus grimmii</topic><topic>parthenogenesis</topic><topic>triploid</topic></subject><relatedItem type="host"><titleInfo><title>Insect Science</title></titleInfo><titleInfo type="abbreviated"><title>Insect Science</title></titleInfo><genre type="journal">journal</genre><subject><genre>article-category</genre><topic>ORIGINAL ARTICLE</topic></subject><identifier type="ISSN">1672-9609</identifier><identifier type="eISSN">1744-7917</identifier><identifier type="DOI">10.1111/(ISSN)1744-7917</identifier><identifier type="PublisherID">INS</identifier><part><date>2013</date><detail type="volume"><caption>vol.</caption><number>20</number></detail><detail type="issue"><caption>no.</caption><number>3</number></detail><extent unit="pages"><start>345</start><end>357</end><total>13</total></extent></part></relatedItem><identifier type="istex">103BA6149FC9A48222729F638F52F395CA2BEE0A</identifier><identifier type="DOI">10.1111/j.1744-7917.2012.01564.x</identifier><identifier type="ArticleID">INS1564</identifier><accessCondition type="use and reproduction" contentType="copyright">© 2013 Institute of Zoology, Chinese Academy of Sciences© 2012 Institute of Zoology, Chinese Academy of Sciences</accessCondition><recordInfo><recordContentSource>WILEY</recordContentSource></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
