Log (variance) plotted against log(average) for (a) daily rainfall and (b) daily catches of BPH adults.

Abstract

<p>Each dot represents a month. The straight line for daily rainfall is described by <i>y = </i>1.3068<i>x</i>+0.1252 (<i>R</i>² = 0.9587) and for daily catches of BPH by <i>y = </i>2.0512<i>x</i>–0.2258 (<i>R</i>² = 0.9793).</p
