When fertilization is internal, this means that rival males\u2019 sperm must compete within the female reproductive tract to reach the eggs. Males of diverse species deposit a mating plug during copulation, which is hypothesized to assist in the race for fertilization following multiple mating. Here, we tested this by using stable isotope labeling to discriminate the ejaculates of competing male voles in direct competition. This revealed that the mating plug simultaneously inhibits the sperm of rival males while promoting transport of a male\u2019s own sperm, both of which are beneficial in the competition for fertilizations.<\/jats:p>","DOI":"10.1073\/pnas.1920526117","type":"journal-article","created":{"date-parts":[[2020,10,20]],"date-time":"2020-10-20T00:31:17Z","timestamp":1603153877000},"page":"27465-27473","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":22,"title":["Revealing mechanisms of mating plug function under sexual selection"],"prefix":"10.1073","volume":"117","author":[{"given":"Paula","family":"Stockley","sequence":"first","affiliation":[{"name":"Mammalian Behaviour and Evolution Group, Institute of Infection, Veterinary and Ecological Sciences, University of Liverpool, CH64 7TE Neston, United Kingdom;"}]},{"given":"Catarina","family":"Franco","sequence":"additional","affiliation":[{"name":"Centre for Proteome Research, Institute of Systems, Molecular and Integrative Biology, University of Liverpool, L69 7ZB Liverpool, United Kingdom"}]},{"given":"Amy J.","family":"Claydon","sequence":"additional","affiliation":[{"name":"Centre for Proteome Research, Institute of Systems, Molecular and Integrative Biology, University of Liverpool, L69 7ZB Liverpool, United Kingdom"}]},{"given":"Amanda","family":"Davidson","sequence":"additional","affiliation":[{"name":"Mammalian Behaviour and Evolution Group, Institute of Infection, Veterinary and Ecological Sciences, University of Liverpool, CH64 7TE Neston, United Kingdom;"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6326-8739","authenticated-orcid":false,"given":"Dean E.","family":"Hammond","sequence":"additional","affiliation":[{"name":"Centre for Proteome Research, Institute of Systems, Molecular and Integrative Biology, University of Liverpool, L69 7ZB Liverpool, United Kingdom"}]},{"given":"Philip J.","family":"Brownridge","sequence":"additional","affiliation":[{"name":"Centre for Proteome Research, Institute of Systems, Molecular and Integrative Biology, University of Liverpool, L69 7ZB Liverpool, United Kingdom"}]},{"given":"Jane L.","family":"Hurst","sequence":"additional","affiliation":[{"name":"Mammalian Behaviour and Evolution Group, Institute of Infection, Veterinary and Ecological Sciences, University of Liverpool, CH64 7TE Neston, United Kingdom;"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0857-495X","authenticated-orcid":false,"given":"Robert J.","family":"Beynon","sequence":"additional","affiliation":[{"name":"Centre for Proteome Research, Institute of Systems, Molecular and Integrative Biology, University of Liverpool, L69 7ZB Liverpool, United Kingdom"}]}],"member":"341","published-online":{"date-parts":[[2020,10,19]]},"reference":[{"key":"e_1_3_4_1_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.867055"},{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-185X.1970.tb01176.x"},{"key":"e_1_3_4_3_2","first-page":"322","volume-title":"Primate Sexuality: Comparative Studies of the Prosimians, Monkeys, Apes and Humans","author":"Dixson A.
