We favor the idea that because termites are, at times (such as during cold weather) unavailable on the soil surface, aardwolves face periods of prolonged fasting.
In a previous laboratory study, we measured the oxygen consumption and evaporative water loss of aardwolves during both summer and winter at ambient temperatures ranging from 5 [degrees] to 35 [degrees] C (Anderson et al.
Further, we quantified the activity budget of aardwolves during summer and winter to construct a time-energy budget for them, thereby examining their seasonal patterns of energy allocation.
We studied aardwolves for two years, from December 1988 to January 1991, on a 2015-ha study plot on the Benfontein Game Farm (28 [degrees] 50 [minutes] S, 24 [degrees] 50 [minutes] E), located [approximately]6 km southeast of Kimberley, South Africa.
The natural history of aardwolves has been described by Richardson (1987a), Koehler and Richardson (1990), Skinner and Smithers (1990), Anderson (1994), and Van Jaarsveld et al.
Within each territory, aardwolves construct 5-6 dens, usually by enlarging vacant springhare (Pedetes capensis) burrows (Richardson 1987b, Anderson 1994).
To facilitate locating individual aardwolves and to simultaneously monitor body temperature ([T.
In addition to the data for body mass of aardwolves used in our DLW experiments, we also obtained information on body masses of other aardwolves from several sources.
When feeding on Hodotermes mossambicus, aardwolves consume workers that harvest grasses on the soil surface (Richardson 1987a).
A general accounting of when aardwolves were active during each season was made by noting when radio-tagged animals exited their dens in the afternoon or evening, and when they returned (exit and entrance times were recorded for 2-3 d for each aardwolf each season).
Aardwolves were accustomed to our vehicle and would allow us to approach within 15-40 m, depending on the animal.
