Ranges of stable coexistence depending on and at seven distinct values of .

<p>The black dot shows the equilibrium corresponding to the parameters of <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0044727#pone-0044727-t001" target="_blank">Table 1</a>. The horizontal segment containing the dot is the same coexistence interval appearing in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0044727#pone-0044727-g004" target="_blank">Figure 4</a>. The other two horizontal segments show the stable coexistence intervals for and within the wedge. For every fixed value of , the range of stable coexistence in the plane forms a triangular wedge.</p>
