Arising from S. Pawar, A. I. Dell & V. M. Savage 486, 485-489 10.1038/nature11131(2012)A recent paper by Pawar and colleagues has provided important insights into the consequences of foraging behaviour for food-web dynamics. One notable pattern predicted by their analysis is that consumption rate (c) scales superlinearly (cm(1.16)) with consumer body mass (m) in three-dimensional (3D), but not two-dimensional (2D), foraging spaces. Although we feel that the authors should be applauded for this interesting contribution, we argue that their result is not consistent with established life-history theory. To resolve this contradiction, progress in both fields is probably required, including new empirical studies in which consumption rate, metabolism and dimensionality are examined directly under natural conditions.
