Surface temperature of back, ear and brown adipose tissue (BAT) of isolated (G1) and huddling (G6) pups, non-insulated and insulated, exposed at 23°C and 14°C.

<p>The results of post-hoc Tukey tests are shown by the letters a to c: same letter showed no significant difference. Left panel: Thermal images are shown for isolated (G1) and huddling (G6) non-insulated and insulated pups, exposed to an ambient temperature of 14°C. Images show the location of circles used to compare surface temperature (total area, back, ear, brown adipose tissue (BAT)).
