Here, we investigated the relationship between heart rate, oxygen consumption and core body temperature during digestion in five pythons (Python bivittatus) by implantation of data loggers. The snakes were placed in respirometers at 30\u00b10.1\u00b0C for 26\u2005days and voluntarily ingested three meals of different size, whilst heart rate, core body temperature and oxygen consumption rate were measured continuously. Both oxygen consumption and heart rate increased severalfold during digestion, and metabolic heat production increased core body temperature by 2\u00b0C, explaining 12% of the observed tachycardia. The rise in core body temperature means that standard metabolic rate increased during digestion, and we estimate that failure to account for core body temperature leads to a 4% overestimation of the specific dynamic action (SDA) response. Our study reveals a close correlation between oxygen consumption and heart rate during digestion, further supporting the use of heart rate as a proxy for metabolism.<\/jats:p>","DOI":"10.1242\/jeb.248021","type":"journal-article","created":{"date-parts":[[2024,9,25]],"date-time":"2024-09-25T04:31:43Z","timestamp":1727238703000},"source":"Crossref","is-referenced-by-count":5,"title":["Proportional increment of oxygen consumption, heart rate and core body temperature in the digesting\n                    <i>Python bivittatus<\/i>"],"prefix":"10.1242","volume":"227","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-6581-6617","authenticated-orcid":false,"given":"Katja B.","family":"Last","sequence":"first","affiliation":[{"name":"Aarhus University, Universitetsparken Zoophysiology, Department of Biology , , 8000 Aarhus C ,","place":["Denmark"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans","family":"Malte","sequence":"additional","affiliation":[{"name":"Aarhus University, Universitetsparken Zoophysiology, Department of Biology , , 8000 Aarhus C ,","place":["Denmark"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emil","family":"Rindom","sequence":"additional","affiliation":[{"name":"Aarhus University, Universitetsparken Zoophysiology, Department of Biology , , 8000 Aarhus C ,","place":["Denmark"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Igor N.","family":"Guagnoni","sequence":"additional","affiliation":[{"name":"Aarhus University, Universitetsparken Zoophysiology, Department of Biology , , 8000 Aarhus C ,","place":["Denmark"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tobias","family":"Wang","sequence":"additional","affiliation":[{"name":"Aarhus University, Universitetsparken Zoophysiology, Department of Biology , , 8000 Aarhus C ,","place":["Denmark"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","published-online":{"date-parts":[[2024,10,4]]},"reference":[{"key":"2024100609013018800_JEB248021C1","first-page":"313","article-title":"Snake foraging ecology and digestive physiology: Integrative biology and evolving paradigms","volume-title":"Snakes","author":"Alexander","year":"2023"},{"key":"2024100609013018800_JEB248021C2","first-page":"485","article-title":"Meal size and specific dynamic action in the rattlesnake Crotalus durissus (Serpentes: Viperidae)","volume":"53","author":"Andrade","year":"1997","journal-title":"Herpetologica"},{"key":"2024100609013018800_JEB248021C3","doi-asserted-by":"publisher","first-page":"207","DOI":"10.1111\/j.1095-8649.1986.Tb05012.x","article-title":"Heart rate as an indicator of activity, metabolic rate, food intake and digestion in pike, Esox lucius","volume":"29","author":"Armstrong","year":"1986","journal-title":"J.
