Siberian hamsters (<jats:italic>Phodopus sungorus<\/jats:italic>) primarily rely on photoperiod as a predictive cue of future energy availability. When raised in long\u2010day photoperiods (&gt;14\u2009h light), supplemental cues such as food availability typically do not trigger the seasonal reproductive response of gonadal regression, which curtails reproduction in unsuitable environments. We investigated whether recognition of food availability as a cue could be altered by a nutritional challenge during development. Specifically, we predicted that hamsters receiving restricted food during development would be sensitized to food restriction (FR) as adults and undergo gonadal regression in response. Male and female hamsters were given either ad libitum (AL) food or FR from weaning until d60. The FR treatment predictably limited growth and delayed puberty in both sexes. For 5 weeks after d60, all hamsters received an AL diet to allow FR hamsters to gain mass equal to AL hamsters. Then, adult hamsters of both juvenile groups received either AL or FR for 6 weeks. Juvenile FR had lasting impacts on adult male body mass and food intake. Adult FR females exhibited decreased estrous cycling and uterine horn mass indiscriminately of juvenile food treatment, but there was little effect on male reproductive measurements. Overall, we observed a delay in puberty in response to postweaning FR, but this delay appeared not to affect seasonal reproductive responses in the long term. These findings increase our understanding of seasonal reproductive responses in a relevant environmental context.<\/jats:p>","DOI":"10.1002\/jez.2534","type":"journal-article","created":{"date-parts":[[2021,8,3]],"date-time":"2021-08-03T19:14:21Z","timestamp":1628018061000},"page":"691-702","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Food restriction during development delays puberty but does not affect adult seasonal reproductive responses to food availability in Siberian hamsters (<i>Phodopus sungorus<\/i>)"],"prefix":"10.1002","volume":"335","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2701-8185","authenticated-orcid":false,"given":"Allison M.","family":"Bailey","sequence":"first","affiliation":[{"name":"Department of Biology Indiana University  Bloomington Indiana USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlisha A.","family":"Hall","sequence":"additional","affiliation":[{"name":"Department of Biology University of North Carolina  Pembroke North Carolina USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandra J.","family":"Legan","sequence":"additional","affiliation":[{"name":"Department of Physiology University of Kentucky  Lexington Kentucky USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gregory E.","family":"Demas","sequence":"additional","affiliation":[{"name":"Department of Biology Indiana University  Bloomington Indiana USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,8,3]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/1365-2435.12846"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.physbeh.2016.09.023"},{"key":"e_1_2_8_4_1","first-page":"161","volume-title":"Essays on aspects of evolutionary biology","author":"Baker J.
