Metabolic adjustments of a wild passerine to acute stress and heat acclimation

Data were collected during a study on Arizona House Finches in which we compared morphological characteristics, food intake, and blood metabolite concentrations in a CONTROL group (COLD group, C) with those in a heat-exposed group (HOT group, H). Data were collected for each bird at the time of capture (morphology only) and in captivity, before (PRE-TREATMENT) and then one and two weeks after birds were randomly assigned to the COLD or the HOT treatment. In addition, blood metabolite concentrations were measured at baseline and again after 30 min of handling/mild restraint stress.本研究以亚利桑那朱雀（Arizona House Finches）为研究对象，对比了低温对照组（COLD组，即CONTROL group，缩写为C）与热暴露组（HOT组，即heat-exposed group，缩写为H）的形态学特征、食物摄入量及血液代谢物浓度。研究数据的采集节点如下：每只受试个体于捕获时仅采集形态学数据；在圈养环境下，分别于随机分配至低温或高温处理前（预处理阶段，PRE-TREATMENT）、处理后1周及2周时完成数据采集。此外，血液代谢物浓度在基线状态（baseline）下完成测定，并在受试个体经历30分钟抓取/轻度束缚应激（handling/mild restraint stress）后再次进行检测。
