Fig. 1

Feeding migration model schematic (Model 3). Space is restricted to a 1 dimonsional loop (black dashed line). The green curve shows the time-varying carrying capacity at all points in this space (Eq. 10). A patch of favorable conditions translates steadily through space with speed v K . The location and height of the blue bar indicate the location (X) and size (N) of the migratory population, respectively. The population tracks the patch with a speed, \(\frac {dX}{dt}\), that is dependent on the local strength of the resource gradient and the size of the population (Eq. 13). The z-axis applies to both carrying capacity (green curve) and population size (height of blue bar) and is thus in units of number of animals. See Additional files 2, 3, and 4 (Animation 1–3) for animations of the simulation
