Optimal sampling interval for characterisation of the circadian rhythm of body temperature in homeothermic animals using periodogram and cosinor analysis

Core body temperature (Tc) is a critical aspect of homeostasis in birds and mammals and is increasingly used as a biomarker of the fitness of an animal to its environment. Periodogram and cosinor analysis can be used to estimate the characteristics of the circadian rhythm of Tc from data obtained on loggers that have limited memory capacity and battery life. This data set contains five days of core body temperature, measured by loggers implanted into the abdominal cavity, in nine species of birds and mammals., Raw data collected by temperature loggers implanted into the abdominal cavity of nine species of birds and mammals. All of the data were calibrated against a certified mercury in glass thermometer, or a certified platinum thermometer. All data are in degrees Celsius., , # Optimal sampling interval for characterisation of the circadian rhythm of body temperature in homeothermic animals using periodogram and cosinor analysis

Five days of core body temperature from nine species of bird and mammal. The number of individuals per species varies (alpaca n = 22, cheetah n = 5, mouse n = 6, barnacle goose n = 9, Pekin duck n = 19, rabbit n = 36, rat n = 6, sheep n = 12, blue wildebeest n = 6).

## Description of the data and file structure

The date are provided as an excel file with one worksheet per species. Individual animals are in columns on each time. A time stamp is given in the first column of each worksheet. All of the data were calibrated against a certified mercury in glass thermometer before and after deployment.

## Sharing/Access information

Five random days from each species were chosen for analysis. Total deployment in each species varied from weeks to months. ...

核心体温（Core body temperature, Tc）是维持鸟类与哺乳动物体内稳态的关键指标，如今亦愈发广泛用作评估动物对环境适应能力的生物标志物。周期图法（periodogram）与余弦拟合分析（cosinor analysis）可依托内存与电池容量均有限的体温记录器（logger）采集的数据，估算核心体温的昼夜节律特征。本数据集包含9种鸟类和哺乳动物的腹腔植入式体温记录器采集的5天核心体温原始数据，所有数据均经经认证的玻璃水银温度计或铂电阻温度计校准，单位为摄氏度。
