The scale-free structure of the stimulus landscape.

<p>Both panels depict the survivorship (the complement of the cumulative distribution) function for: a) mean site occupancy, <<i>p</i>> and b) The mean cluster size, , normalised by the maximum cluster possible, <i>l</i>×<i>l</i>. Both <<i>p</i>> and are ensemble-averages, calculated by averaging across all individuals irrespective of threshold. The different curves represent different fixed drives (○; δS = 1×10⁻², ⧫; δS = 1×10⁻¹, •; δS = 1×10⁰, ▪; δS = 1×10¹).
