Figure 5. Thermal imaging of new-born pups from (A) Ucp1 (N = 7, n = 12–29) and (B) Cox7a1 (N = 5, n = 5–15) knockout breeding pairs.

Pups were derived from heterozygous breeding and entire litters were subjected to imaging. Interscapular skin surface temperature (iSST) was used as measure for BAT activity. Data were analysed by One Way ANOVA on Ranks and Dunn’s multiple comparison test (*p < 0.05; ***p < 0.001).
