Fig. 4. Frequency distribution of Tb values from six echidnas
(five female, one male, black bars) and Tref (grey bars),
in May and July. In May the majority of Tref readings
(70%) were in the range 912°C, as were 70% of
Tb readings, but Tb values below
9°C are under-represented (4%) compared with Tref
(17%). In July the distribution of Tb values is
significantly offset compared with Tref. 58% of recorded
Tref values were between 6 and 8°C, but 62% of
Tb values were between 8 and 10°C.
