Fig. 3. Differential resource encounter by a forager when the environment is uniform (left column) or fractal (right column). The green box represents the area searched by a forager, while black boxes represent a resource such as food. N is a count of the number of resource cells encountered with the subscripts u and f representing uniform and fractal landscapes, respectively. A change in forager size and hence search area is represented by the green squares over the top of the resource distributions. Forager size, and therefore search area, increases down each column from a 3 x 3 square to a 9 x 9 square of arbitrary units. As search area increases, the number of cells occupied (Nu and Nf) increases in both distributions (columns), but it does so less quickly in the fractal distribution.
