Fig. 7. Results of the cold plunge protocol for a 3-day-old dunlin Calidris
alpina chick (filled symbols) compared with a downup (DU) protocol
for a dunlin chick of the same age (open symbols). Oxygen consumption
O2 on a
logarithmic scale is plotted as a function of body temperature
Tb (A) and the temperature gradient
T
(Tb-Ta) (B) during Phase I.
