This study investigated whether seasonal or acute acclimation to anticipated or actual energetic challenges in Djungarian hamsters also resulted in higher nutrient resorption capacities due to changes in small intestine histology and physiology. The hamsters show numerous seasonal energy saving adjustments in response to short photoperiod. As spontaneous daily torpor represents one of these adjustments related to food quality and quantity, it was hypothesized that the hamsters\u2019 variable torpor expression patterns are influenced by their individual nutrient uptake capacity. Hamsters under short photoperiod showed longer small intestines and higher mucosal electrogenic transport capacities for glucose relative to body mass. Similar observations were made in hamsters under long photoperiod and food restriction. However, this acute energetic challenge caused a stronger increase of glucose transport capacity. Apart from that, neither fasting-induced torpor in food-restricted hamsters nor spontaneous daily torpor in short photoperiod-exposed hamsters clearly correlated with mucosal glucose transport capacity.<\/jats:p>\n               <jats:p>Both seasonally anticipated and acute energetic challenges caused adjustments in the hamsters\u2019 small intestine. Short photoperiod appeared to induce an integration of these and other acclimation processes in relation to body mass to achieve a long-term adjustment of energy balance. Food restriction seemed to result in a more flexible, short-term strategy of maximizing energy uptake possibly via mucosal glucose transport and reducing energy consumption via torpor expression as emergency response.<\/jats:p>","DOI":"10.1242\/jeb.232876","type":"journal-article","created":{"date-parts":[[2020,12,29]],"date-time":"2020-12-29T16:05:29Z","timestamp":1609257929000},"source":"Crossref","is-referenced-by-count":13,"title":["Acclimation of intestinal morphology and function in djungarian hamsters (<i>Phodopus sungorus<\/i>) related to seasonal and acute energy balance"],"prefix":"10.1242","author":[{"given":"Emiliana","family":"Piscitiello","sequence":"first","affiliation":[{"name":"Department of Biomedical and Neuromotor Sciences, University of Bologna, Piazza di Porta San Donato 2, 40126 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annika","family":"Herwig","sequence":"additional","affiliation":[{"name":"Institute of Neurobiology, Ulm University, Albert-Einstein-Allee 11, 89081 Ulm, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena","family":"Haugg","sequence":"additional","affiliation":[{"name":"Institute of Neurobiology, Ulm University, Albert-Einstein-Allee 11, 89081 Ulm, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernd","family":"Schr\u00f6der","sequence":"additional","affiliation":[{"name":"Institute of Physiology and Cell Biology, University of Veterinary Medicine Hannover, Bischofsholer Damm 15, 30173 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gerhard","family":"Breves","sequence":"additional","affiliation":[{"name":"Institute of Physiology and Cell Biology, University of Veterinary Medicine Hannover, Bischofsholer Damm 15, 30173 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephan","family":"Steinlechner","sequence":"additional","affiliation":[{"name":"Department of Zoology, University of Veterinary Medicine Hannover, B\u00fcnteweg 17, 30559 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7963-4553","authenticated-orcid":false,"given":"Victoria","family":"Diedrich","sequence":"additional","affiliation":[{"name":"Institute of Neurobiology, Ulm University, Albert-Einstein-Allee 11, 89081 Ulm, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","published-online":{"date-parts":[[2020,1,1]]},"reference":[{"key":"2021042623090787100_JEB232876C1","doi-asserted-by":"publisher","first-page":"1095","DOI":"10.1139\/z95-130","article-title":"Seasonal changes in gut morphology of the striped field mouse (Apodemus agrarius)","volume":"73","author":"Borkowska","year":"1995","journal-title":"Can.
