Solutions of Eq (7) and their stabilities under dynamics (2) when <i>c</i>₁ > 0 and <i>c</i>₂ = 0.

<p>Intersections of <i>h</i>₁(<i>q</i>) and <i>h</i>₂(<i>q</i>) (i.e., the solutions of <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0142929#pone.0142929.e041" target="_blank">Eq (7)</a>) are shown for all sixteen possible situations. The red curves denote <i>h</i>₁(<i>q</i>) and the green curves <i>h</i>₂(<i>q</i>). The intersections denoted by black spots correspond to stable equilibria of dynamics (2), and the intersections denoted by black circles correspond to unstable equilibria. Parameters are taken as <i>β</i>₁ = <i>β</i>₂ = 0.01, <i>α</i>₁ = 1, <i>α</i>₂ = 2 and <i>c</i>₁ = 0.5 in all sixteen panels.
