Overall size (measured as snout\u2013vent length), on the other hand, is not different between the two sexes. We use data on bite scar frequency and fecundity to evaluate competing hypotheses regarding the selective forces driving these patterns. We contend that sexual selection, acting through male\u2010male competition, may favor larger mass and head size in males, whereas large females are likely favored by natural selection for greater fecundity. In addition, the frequency of opposite\u2010sex patterning in males versus females may indicate that the costs of agonistic interactions among males are severe enough to allow for an alternative mating strategy. Finally, we discuss how sexual and natural selective forces may interact to drive or mask the evolution of sexually dimorphic traits.<\/jats:p>","DOI":"10.1002\/ece3.455","type":"journal-article","created":{"date-parts":[[2012,12,26]],"date-time":"2012-12-26T12:06:32Z","timestamp":1356523592000},"page":"255-261","source":"Crossref","is-referenced-by-count":10,"title":["Patterns of sexual dimorphism in Mexican alligator lizards, <i>Barisia imbricata<\/i>"],"prefix":"10.1002","volume":"3","author":[{"given":"Daniel","family":"Dashevsky","sequence":"first","affiliation":[{"name":"Department of Biology Reed College Portland Oregon"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jesse M.","family":"Meik","sequence":"additional","affiliation":[{"name":"Department of Biology University of Texas Arlington Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Estrella","family":"Moci\u00f1o\u2010Deloya","sequence":"additional","affiliation":[{"name":"Departmento de Biologia Animal Universidad de Granada Granada Espa\u00f1a"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kirk","family":"Setser","sequence":"additional","affiliation":[{"name":"Departmento de Biologia Animal Universidad de Granada Granada Espa\u00f1a"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Schaack","sequence":"additional","affiliation":[{"name":"Department of Biology Reed College Portland Oregon"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2012,12,26]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00318265"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0169-5347(02)02569-7"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-7998.2008.00484.x"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.0014-3820.2003.tb01489.x"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.0014-3820.2000.tb00026.x"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature09020"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1086\/284266"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1086\/284948"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1558-5646.2009.00791.x"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.0014-3820.2003.tb00371.x"},{"key":"e_1_2_7_12_1","volume-title":"The descent of man, and selection in relation to sex","author":"Darwin C.","year":"1871"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2148-9-278"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1442-9993.2010.02119.x"},{"key":"e_1_2_7_15_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1093\/acprof:oso\/9780199208784.001.0001","volume-title":"Sex, size, and gender roles: evolutionary studies of sexual size dimorphism","author":"Fairbairn D.
