1. Movement based indices such as Moves Per Minute (MPM) and Proportion Time Moving (PTM) are common methodologies to quantify foraging behavior. We explore fundamental drawbacks of these indices, question the ways scientists have been using them, and propose new solutions. 2. To do so, we combined analytical and simulation models with lizards foraging data at the individual and species levels. 3. We found that the maximal value of MPM is constrained by the minimal...
