The structure of the stimulus landscape- and hence also the bout magnitude- are nonlinear functions of the individual response-threshold.

Abstract

<p><b>a</b>) Mean cluster size, , normalised by dividing by the maximum cluster possible, <i>l</i>² and b) Mean standardised bout size (size/drive) for individual ant-bouts. Ants were assigned to threshold bins of logarithmically increasing width. The different curves represent different fixed drives (N simulations per drive = 500, ○; δS = 1×10⁻², ⧫; δS = 1×10⁻¹, •; δS = 1×10⁰, ▪; δS = 1×10¹).</p
