The reproductive behaviour of the land snail <jats:italic>Helix aspersa<\/jats:italic> involves several features, like multiple mating, long\u2010term sperm storage and dart\u2010shooting behaviour, which may promote sperm competition. Cryptic female choice may also occur through a spermatheca subdivided into tubules, which potentially allows compartmentalized sperm storage of successive mates. In order to determine the outcome of postcopulatory sexual selection in this species, we designed a cross\u2010breeding experiment where a recipient (\u2018female\u2019) mated with two sperm donors (\u2018males\u2019). Mates came from either the same population as the recipient or from a distinct one. To test for the influence a recipient can have on the paternity of its offspring, we excluded the effects of dart shooting by using only virgin snails as sperm donors because they do not shoot any dart before their first copulation. We measured the effects of size of mates as well as time to first and second mating on second mate sperm precedence (<jats:italic>P<\/jats:italic><jats:sub>2<\/jats:sub>; established using microsatellite markers). Multiple paternity was detected in 62.5% of clutches and overall there was first\u2010mate sperm precedence with a mean <jats:italic>P<\/jats:italic><jats:sub>2<\/jats:sub> of 0.24. Generalized linear modelling revealed that the best predictors of paternity were the time between matings and the time before first mating. Overall, both first and second mates that copulated quickly got greater parentage, which may suggest that postcopulatory events influence patterns of sperm precedence in the garden snail.<\/jats:p>","DOI":"10.1111\/j.1365-294x.2005.02449.x","type":"journal-article","created":{"date-parts":[[2005,2,21]],"date-time":"2005-02-21T10:15:53Z","timestamp":1108980953000},"page":"805-812","source":"Crossref","is-referenced-by-count":51,"title":["Multiple paternity and postcopulatory sexual selection in a hermaphrodite: what influences sperm precedence in the garden snail <i>Helix aspersa<\/i>?"],"prefix":"10.1111","volume":"14","author":[{"given":"GUILLAUME","family":"EVANNO","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"LUC","family":"MADEC","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JEAN\u2010FRAN\u00c7OIS","family":"ARNAUD","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,2,7]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1139\/z88-211"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1515\/9780691207278"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1095-8312.2004.00320.x"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2540.1999.00565.x"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-294X.2001.01292.x"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-7998.1999.tb00754.x"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-3472(05)80109-5"},{"key":"e_1_2_6_9_1","doi-asserted-by":"crossref","unstructured":"BaurB(1994)Multiple paternity and individual variation in sperm precedence in the simultaneously hermaphroditic land snailArianta arbustorum.Behavioral Ecology and Sociobiology 35 413\u2013421.","DOI":"10.1007\/BF00165844"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1038\/hdy.1992.95"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.2307\/3226861"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1038\/nrg774"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.0014-3820.2001.tb00740.x"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0169-5347(02)00004-6"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.76.5.2480"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1038\/hdy.1993.163"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1093\/mollus\/52.3.253"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.1098\/rstb.1997.0061"},{"key":"e_1_2_6_19_1","first-page":"309","volume-title":"Pulmonates (","author":"Duncan CJ","year":"1975"},{"key":"e_1_2_6_20_1","doi-asserted-by":"crossref","DOI":"10.1515\/9780691207209","volume-title":"Female Control: Sexual Selection by Cryptic Female Choice.","author":"Eberhard WG","year":"1996"},{"key":"e_1_2_6_21_1","first-page":"295","article-title":"Rapid one\u2010tube DNA extraction for reliable PCR detection of fish polymorphic markers and transgenes","volume":"5","author":"Estoup A","year":"1996","journal-title":"Molecular Marine Biology and Biotechnology"},{"key":"e_1_2_6_22_1","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.2000.1577"},{"key":"e_1_2_6_23_1","unstructured":"FearnleyRH(1993)Sexual selection dispersal and reproductive behaviour in hermaphrodite land snails with particular reference toHelix AspersaM\u00fcller.
