الملخصBiologists focus on thermoregulation of desert mammals in terms of how they minimize heat gain, and put less effort on how they maximize heat gain during the cooler months. Heat gain may contribute to significant energy savings in desert mammals when the ambient temperature is substantially lower than body temperature. We investigated winter thermoregulation in free-ranging Ethiopian hedgehogs, Paraechinus aethiopicus, during winter using radio-telemetry in Qatar. Hedgehog temperatures (Animal Ta) were significantly higher than ambient temperatures (Ta) throughout the day, the difference was more extreme during the mid-day. We observed several hedgehogs basking with their radio-tags exposed to direct sunlight. We suggest that basking is beneficial for the hedgehog's thermoregulation in the desert where plenty of solar radiation is available with few predators. This is the first report of basking in the subfamily Erinaceinae.
راعي المشروعThis report was made possible by a NPRP award (NPRP 5-083-1-019) from the Qatar National Research Fund (a member of The Qatar Foundation). We are grateful to the Ministry of Environment of Qatar and the staff at Rawdat Al Faras Agricultural Research Center for providing access to the site and for logistical support. We also acknowledge the input from five anonymous reviewers that greatly improved the manuscript.
