体温（T-b）是生态生理学研究的关键参数之一，重点是节能策略。因此，在这项研究中，我们比较评估了两种类型的温度敏感的被动转发器（生命芯片和IPTT-300）和一个数据记录器（iButton，DS 1922 L）安装到一个衣领，以测量T-b在现场的有用性。首先，我们在水浴中测试了所有三种设备的准确性，水温范围从0到40摄氏度。第二，我们评估了生命芯片和改进的生物芯片在野外条件下测量小型异温哺乳动物T-b的有用性。在这项工作中，我们皮下植入14只雄性可食用睡鼠（Glis glis）与转发器，并配备了另外14名男性的数据记录器，同时记录T-b和氧气消耗与便携式氧气分析仪（Oxbox）。在一个人身上，我们用两种设备记录了T-b，并分析了记录的T-b模式。生命芯片能够测量25至40摄氏度的最小范围内的温度，精度为0.07 +/- 0.12摄氏度。IPTT-300转发器测量的温度在10至40摄氏度之间，但在低于30摄氏度时，准确度大幅下降，最大偏差接近7摄氏度。因此，在以低TbS使用每个应答器之前，需要对每个应答器进行单独校准。数据记录仪的准确性相对较好（0.12 +/- 0.25 ℃），在整个测试温度范围（0-40 ℃）内稳定。在所有三种设备中，测量的可重复性都很高。LifeChip应答器以及修改后的iPhone4在现场条件下可靠地测量T-b。在一只植入生命芯片和安装在项圈上的iButton的可食用睡鼠中同时记录T-b，发现两种测量值密切相关。两者合计，我们得出结论，植入的温度敏感的应答器是一个适当的，很大程度上是非侵入性的方法来测量Tb也在现场条件下。(C)2014爱思唯尔有限公司版权所有。
Body temperature (T-b) represents one of the key parameters in ecophysiological studies with focus on energy saving strategies. In this study we therefore comparatively evaluated the usefulness of two types of temperature-sensitive passive transponders (LifeChips and IPTT-300) and one data logger (iButton, DS1922L) mounted onto a collar to measure T-b in the field. First we tested the accuracy of all three devices in a water bath with water temperature ranging from 0 to 40 degrees C. Second, we evaluated the usefulness of the LifeChips and the modified iButtons for measuring T-b of small heterothermic mammals under field conditions. For this work we subcutaneously implanted 14 male edible dormice (Glis glis) with transponders, and equipped another 14 males with data loggers to simultaneously record T-b and oxygen consumption with a portable oxygen analyzer (Oxbox). In one individual we recorded T-b with both devices and analyzed recorded T-b patterns.LifeChips are able to measure temperature within the smallest range from 25 to 40 degrees C with an accuracy of 0.07 +/- 0.12 C. IPTT-300 transponders measured temperature between 10 and 40 degrees C, but accuracy decreased considerably at values below 30 degrees C, with maximal deviations of nearly 7 degrees C. An individual calibration of each transponder is therefore needed, before using it at low TbS. The accuracy of the data logger was comparatively good (0.12 +/- 0.25 degrees C) and stable over the whole temperature range tested (0-40 degrees). In all three devices, the repeatability of measurements was high.LifeChip transponders as well as modified iButtons measured T-b reliably under field conditions. Simultaneous T-b-recordings in one edible dormouse with an implanted LifeChip and a collar-mounted iButton revealed that values of both measurements were closely correlated. Taken together, we conclude that implanted temperature-sensitive transponders represent an appropriate and largely non-invasive method to measure Tb also under field conditions.
