Yet, we often lack information on how certain physiological traits covary with temperature across time. Here, we test predictions on how one trait\u2014lipid content\u2014covaries with temperature using a conspicuous, ground-dwelling harvester ant. We focus on lipid content as fat bodies are metabolically active tissues that are important for storing and releasing energy in response to demand, which could be vital for survival under variable temperatures. From March to November, we extracted lipids from surface workers of 14 colonies while simultaneously recording ground temperature. We first assessed if lipid content was highest during cooler temperatures when ants were less active and less metabolically stressed. In doing so, we found that lipid content of ants declined almost 70% from cool months (November lipid content = 14.6%) to hot months (August lipid content = 4.6%). We next assessed if lipid levels from a group of ants collected at a single time point could change by placing individuals into environmental chambers set at 10, 20, and 30\u00b0C (i.e., the approximate span of average temperatures from March to November). Temperature again had a significant impact such that after 10 days, lipid content of ants in the hottest chamber (30\u00b0C) had decreased by more than 75%. While intraspecific variation in physiological traits often follows seasonal patterns, our results suggest fluctuations in temperature may account for a portion of the variance observed in traits like lipid content.<\/jats:p>","DOI":"10.1093\/jisesa\/iead040","type":"journal-article","created":{"date-parts":[[2023,6,10]],"date-time":"2023-06-10T12:54:55Z","timestamp":1686401695000},"source":"Crossref","is-referenced-by-count":7,"title":["Temperature influences lipid content in the red harvester ant, <i>Pogonomyrmex barbatus<\/i>"],"prefix":"10.1093","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2366-9781","authenticated-orcid":false,"given":"Diane V","family":"Roeder","sequence":"first","affiliation":[{"name":"Department of Natural Resource Management, South Dakota State University , Brookings, SD 57006 , USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samantha","family":"Remy","sequence":"additional","affiliation":[{"name":"Department of Agriculture, Biology and Health Sciences, Cameron University , Lawton, OK 73505 , USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2628-5003","authenticated-orcid":false,"given":"Karl A","family":"Roeder","sequence":"additional","affiliation":[{"name":"Agricultural Research Service, North Central Agricultural Research Laboratory, USDA , Brookings, SD 57006 , USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2023,6,10]]},"reference":[{"key":"2023061012544874300_CIT0001","doi-asserted-by":"crossref","first-page":"207","DOI":"10.1146\/annurev-ento-112408-085356","article-title":"Insect fat body: energy, metabolism, and regulation","volume":"55","author":"Arrese","year":"2010","journal-title":"Annu Rev Entomol."},{"key":"2023061012544874300_CIT0002","doi-asserted-by":"crossref","first-page":"1","DOI":"10.18637\/jss.v067.i01","article-title":"Fitting linear mixed-effects models using lme4","volume":"67","author":"Bates","year":"2015","journal-title":"J Stat Softw."},{"issue":"1","key":"2023061012544874300_CIT0003","doi-asserted-by":"crossref","first-page":"99","DOI":"10.1098\/rsbl.2007.0408","article-title":"Thermal tolerance, acclimatory capacity and vulnerability to global climate change","volume":"4","author":"Calosi","year":"2008","journal-title":"Biol Lett."},{"key":"2023061012544874300_CIT0004","doi-asserted-by":"crossref","first-page":"23","DOI":"10.1146\/annurev.nutr.21.1.23","article-title":"Fat metabolism in insects","volume":"21","author":"Canavoso","year":"2001","journal-title":"Annu Rev Nutr."},{"issue":"3","key":"2023061012544874300_CIT0005","doi-asserted-by":"crossref","first-page":"649","DOI":"10.1093\/icb\/icx029","article-title":"Who are the \u2018lazy\u2019 ants?
