We considered 3 classes of<jats:italic>G. pulex<\/jats:italic>males in our experiments: (i) uninfected males found paired in the field, (ii) uninfected males found unpaired in the field, or (iii) infected males found unpaired in the field. Both infected males and uninfected unpaired males paired less with a new female than uninfected paired males did. Furthermore, infected males appear to be at a strong disadvantage when directly competing for females with a healthy rival male, and had fewer sperm in their testes. We discuss the potential effect of male and female mating strategies on such male host mating alteration.<\/jats:p>","DOI":"10.1017\/s0031182011001247","type":"journal-article","created":{"date-parts":[[2011,8,3]],"date-time":"2011-08-03T11:58:41Z","timestamp":1312372721000},"page":"1429-1435","source":"Crossref","is-referenced-by-count":12,"title":["Pairing success and sperm reserve of male<i>Gammarus pulex<\/i>infected by<i>Cyathocephalus truncatus<\/i>(Cestoda: Spathebothriidea)"],"prefix":"10.1017","volume":"138","author":[{"given":"MATTHIAS","family":"GALIPAUD","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ZO\u00c9","family":"GAUTHEY","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"LO\u00cfC","family":"BOLLACHE","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2011,8,3]]},"reference":[{"key":"S0031182011001247_ref60","doi-asserted-by":"publisher","DOI":"10.1007\/s00442-004-1786-x"},{"key":"S0031182011001247_ref56","doi-asserted-by":"publisher","DOI":"10.1007\/BF00328591"},{"key":"S0031182011001247_ref52","doi-asserted-by":"publisher","DOI":"10.1163\/156853902320387873"},{"key":"S0031182011001247_ref49","doi-asserted-by":"publisher","DOI":"10.1038\/183479c0"},{"key":"S0031182011001247_ref48","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000085127"},{"key":"S0031182011001247_ref46","doi-asserted-by":"publisher","DOI":"10.1006\/anbe.2003.2116"},{"key":"S0031182011001247_ref44","doi-asserted-by":"publisher","DOI":"10.1006\/anbe.2003.2112"},{"key":"S0031182011001247_ref57","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000085139"},{"key":"S0031182011001247_ref43","unstructured":"Okaka C.
