Figure 5. Blood ethanol concentrations (BECs) 90 minutes following a 2.5 g/kg intraperitoneal injection of ethanol.

Meadow voles had significantly higher average BEC than prairie voles in Experiment 1 (A). There was no difference in average BEC of young and old prairie voles in Experiment 2 (B), age-matched to the prairie and meadow voles, respectively, from Experiment 1. Values indicate group mean + standard error of the mean (SEM). * effect of species; p<0.05
