Warming nighttime temperatures and prey availability interact to influence digestive physiology in prairie lizards (Sceloporus consobrinus)

The current study examined the interactions between nighttime warming and prey availability on physiology in praire lizards (Sceloporus consobrinus). There were three nighttime warming treatments, referred to as "current conditions", "2C warming", and "4C wamring" and three prey availability treatments, referred to as "high", "moderate" and "low". We quantified food consumption (kJ), digestive passage time (hours), fecal production (kj), urate production (kJ), metabolizable energy intake (kJ), and assimilated energy (kJ). OVerall, we found interactions between nighttime warming and prey availability on food consumption, passage time, and metabolizable energy. We found direct effects of nighttime warming on fecal and urate production. There is one dataset file, titled "nightwarming_prey_dataset.csv". There are two files containing adjusted mean values used to create plots. One file contains adjusted means for MEI, passage time, and food consumption. The second file contains adjusted means for fecal and urate production.

本研究探讨了夜间增温与猎物可获得性对草原蜥蜴（Sceloporus consobrinus）生理机能的交互作用。本研究设置了三种夜间增温处理，分别命名为'当前环境条件'、'2℃增温'与'4℃增温'，同时设置了三种猎物可获得性处理，分别为'高'、'中等'与'低'。本研究量化了多项生理指标，包括食物消耗量（kJ）、消化通过时间（小时）、粪便产生量（kJ）、尿酸排泄量（kJ）、可代谢能量摄入量（metabolizable energy intake, MEI）以及同化能量。整体而言，研究发现夜间增温与猎物可获得性对食物消耗量、消化通过时间及可代谢能量摄入量存在交互作用；同时发现夜间增温对粪便产生量与尿酸排泄量具有直接影响。本研究附带一个名为"nightwarming_prey_dataset.csv"的数据集文件。另有两个包含用于绘图的校正均值的文件：其一包含可代谢能量摄入量、消化通过时间与食物消耗量的校正均值；其二包含粪便产生量与尿酸排泄量的校正均值。
