摘要

每日异温性是吸热鸟类和哺乳动物采用的一种策略，通过降低代谢率来减少能量消耗。我们记录了三种摩洛哥沙鼠啮齿类动物夜间和白天的直肠温度，以确定异温性的水平。沙billus gerbillus的昼夜体温平均下降(±SD) 8.7(±4.2)°C, amenus gerbillus的昼夜体温平均下降(±SD)为11.1(±3.0)°C, g.p .1的昼夜体温平均下降(±3.3)°C，这是三种动物首次出现异温现象。这一发现支持了一项预测，即在干旱和半干旱地区的哺乳动物中发现了日常异温性，有助于进一步了解沙漠啮齿动物的体温调节。

High level of daily heterothermy in desert gerbils

Daily heterothermy is a strategy employed by endothermic birds and mammals to reduce their energetic costs by lowering their metabolic rate. We recorded nocturnal and diurnal rectal temperatures in three Moroccan Gerbillus rodent species to determine the level of heterothermy. A decrease in body temperature from night to day was observed by an average (±SD) of 8.7 (±4.2) in G. gerbillus, 11.1 (±3.0) in G. amoenus, and 7.7 (±3.3)°C in G. sp.1, the first records of heterothermy in the three species. The findings support a prediction that daily heterothermy is found in mammals from arid and semi-arid regions, contributing to further knowledge of thermoregulation in desert rodents.

期刊介绍： Journal of Tropical Ecology aims to address topics of general relevance and significance to tropical ecology. This includes sub-disciplines of ecology, such as conservation biology, evolutionary ecology, marine ecology, microbial ecology, molecular ecology, quantitative ecology, etc. Studies in the field of tropical medicine, specifically where it involves ecological surroundings (e.g., zoonotic or vector-borne disease ecology), are also suitable. We also welcome methods papers, provided that the techniques are well-described and are of broad general utility. Please keep in mind that studies focused on specific geographic regions or on particular taxa will be better suited to more specialist journals. In order to help the editors make their decision, in your cover letter please address the specific hypothesis your study addresses, and how the results will interest the broad field of tropical ecology. While we will consider purely descriptive studies of outstanding general interest, the case for them should be made in the cover letter.
