Corrigendum to doi: 10.1111/j.1469-7998.2010.00740.x

Unfortunately, the data presented in Table 5 of the original manuscript is incorrect for the gross dry matter intakes (DMI) needed by kangaroos and sheep to meet their daily field metabolic rates (FMR) or basal metabolic rates (BMR). Please see the correct values presented in Corrigendum Table 5. These corrections do not change the biological significance of the behavioural differences we have reported for red kangaroos and sheep. However, our original report of kangaroo dry-sheep-equivalents (DSE) of 0.42 based on DMI was an overestimate. Using the correct values for the gross DMIs needed to satisfy the FMRs of a standard 25-kg red kangaroo and standard 45-kg sheep, we estimate a kangaroo DSE to be 0.37 (Corrigendum Table 5).
