Fig. 3. Sugar preferences of female and male Egyptian fruit bats when food contained either 0% or 1% ethanol. Preferences are expressed as GUD_{Sugar A}/GUD_{Sugar A}+GUD_{Sugar B}. Values smaller than 0.5 denote preference for the sugar in the numerator (Sugar A). The filled circles are means, and the error bars are 95% confidence intervals. Means with error bars above or below the 0.5 line indicate significant differences (one-sample tests, P<0.05). Frc, fructose; Scr, sucrose; Glc, glucose.
