Body size occupation in subclades of Geophagini.

<p>Body size frequency distributions of the <i>Crenicichla-Apistogramma-Satanoperca</i> (CAS) Clade (A) and the <i>Geophagus-Gymnogeophagus-Dicrossus</i> (GGD) Clade (B) of Geophagini. Coloured columns show observed data fitted to 1000 random subsamples of Geophagini each represented by a black line. Silhouettes depict the three most diverse genera for each clade and the primary region of body space occupation, from top-left to bottom right: <i>Apistogramma</i>, <i>Satanoperca</i>, <i>Crenicichla</i>, <i>Dicrossus</i>, <i>Gymnogeophagus</i>, <i>Geophagus</i>. Black arrows indicate potential body size optima supported by the bootstrap analyses.
