Table 1 Statistically significant difference relations (< means: smaller than) between the core temperature Tcore of barrels (w: white, b: black, gh: grey horse, az: artificial zebra, rz: real zebra, gc: grey cattle) compared pairwise for all days and for the hot days (with average Tair > 25 °C) of experiments 1–4.

From: Experimental evidence that stripes do not cool zebras
