As one of the few felids that is predominantly diurnal,cheetahs(Acinonyx jubatus)can be exposed to high heat loads in their natural *** is known about long-term patterns of body temperature and activity(including hunting)in cheetahs because long-term concurrent measurements of body temperature and activity have never been reported for cheetahs,or,indeed,for any free-living *** report here body temperature and locomo-tor activity measured with implanted data loggers over 7 months in 5 free-living cheetahs in *** tem-perature ranged from a maximum of 39°C in summer to−2°C in *** had higher(~0.4°C)max-imum 24-h body temperatures,later acrophase(~1 h),with larger fluctuations in the range of the 24-h body temperature rhythm(approximately 0.4°C)during a hot-dry period than during a cool-dry period,but main-tained homeothermy irrespective of the climatic *** ambient temperatures increased,the cheetahs shifted from a diurnal to a crepuscular activity pattern,with reduced activity between 900 and 1500 hours and increased nocturnal *** timing of hunts followed the general pattern of activity;the cheetahs hunted when they were on the *** hunted if an opportunity presented itself;on occasion they hunted in the midday heat or in total darkness(new moon).Biologging revealed insights into cheetah biology that are not ac-cessible by traditional observer-based techniques.
