No pedigree information was available to estimate heritability or genetic correlations, because the majority of breeder animals on farms were wild\u2010caught. Moreover, as the age of the female breeders could not be accounted for, egg\u2010size measurements were used as proxies. The reproductive traits investigated were clutch size (total number of eggs laid), number of viable eggs, number of eggs that produced a live, healthy hatchling, hatchability, average snout\u2013vent length of the hatchlings and time of nesting. A second data set was also created comprising binary data of whether or not the female nested. Repeatability estimates ranged from 0.24 to 0.68 for the measurable traits, with phenotypic correlations ranging from \u22120.15 to 0.86. Repeatability for whether a female nested or not was 0.58 on the underlying scale. Correlations could not be estimated between the measurement and binary traits because of confounding. These estimates are the first published for crocodilian reproduction traits.<\/jats:p>","DOI":"10.1111\/j.1439-0388.2005.00548.x","type":"journal-article","created":{"date-parts":[[2005,11,7]],"date-time":"2005-11-07T09:29:40Z","timestamp":1131355780000},"page":"361-369","source":"Crossref","is-referenced-by-count":21,"title":["Quantitative analysis of production traits in saltwater crocodiles (<i>Crocodylus porosus<\/i>): I. reproduction traits"],"prefix":"10.1111","volume":"122","author":[{"given":"S.R.","family":"Isberg","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.C.","family":"Thomson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F.W.","family":"Nicholas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.G.","family":"Barker","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Moran","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,11,7]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"119","article-title":"Genetic and non\u2010genetic factors affecting milk production and preweaning litter traits of New Zealand White does under Egyptian conditions","volume":"3","author":"Ayyat M.S.","year":"1995","journal-title":"World Rabbit Sci."},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4615-0811-3_55"},{"key":"e_1_2_7_4_1","first-page":"458","article-title":"Methods for the determination of the physical characteristics of eggs of Alligator mississippiensis: a comparison with other crocodilian and avian eggs","volume":"1","author":"Deeming D.C.","year":"1990","journal-title":"Herp.
