Life-history theory predicts that an organism\u2019s optimal level of investment into reproduction depends upon whether or not the associated \u2018costs\u2019 (such as a decrease in rate of feeding) increase with higher fecundity. Anorexia during pregnancy is widespread among snakes, but there are few field data on fecundity-dependence of such costs. Over a 23-year period, we recorded reproductive condition and feeding status (based on palpation and production of faeces) for 3778 captures of free-ranging female natricine colubrid snakes (keelbacks,\n                    <jats:italic>Tropidonophis mairii<\/jats:italic>\n                    ) in tropical Australia. Pregnancy reduced feeding rates, and that decrease was greatest for females with higher reproductive investment (clutch mass relative to maternal mass). Our long-term data provide the first clear-cut evidence of fecundity-dependent costs of reproduction in free-ranging snakes.\n                  <\/jats:p>","DOI":"10.1098\/rsos.241831","type":"journal-article","created":{"date-parts":[[2025,4,8]],"date-time":"2025-04-08T19:11:11Z","timestamp":1744139471000},"update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Decreased food intake as a fecundity-dependent cost of reproduction in keelback snakes (\n                    <i>Tropidonophis mairii<\/i>\n                    , Colubridae)"],"prefix":"10.1098","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2924-9040","authenticated-orcid":true,"given":"Gregory Paul","family":"Brown","sequence":"first","affiliation":[{"name":"School of Natural Sciences, Macquarie University","place":["Sydney, Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7529-5657","authenticated-orcid":true,"given":"Richard","family":"Shine","sequence":"additional","affiliation":[{"name":"School of Natural Sciences, Macquarie University","place":["Sydney, Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"175","published-online":{"date-parts":[[2025,4,9]]},"reference":[{"key":"e_1_3_8_2_2","doi-asserted-by":"publisher","DOI":"10.1515\/9780691206981"},{"key":"e_1_3_8_3_2","first-page":"749","article-title":"Reproductive effort, offspring size and benefit\u2013cost ratios in the classification of life histories","volume":"4","author":"Charnov EL","year":"2002","unstructured":"Charnov EL . 2002 Reproductive effort, offspring size and benefit\u2013cost ratios in the classification of life histories.
