Morphological Divergence in Male <i>Brachyrhaphis</i>.

<p>Visualization of morphological divergence with centroid size in male <i>Brachyrhaphis roseni</i> (a), <i>B. terrabensis</i> (b), and <i>B. rhabdophora</i> from predator (c) and predator free (d) environments. Thin-plate spline transformations depict the end points of the centroid size axis (i.e. the smallest and largest individuals). Shaded regions are drawn to aid in interpretation. Note the shortening and deepening of the head region and the reduction in the caudle peduncle region in large males. Deformations are scaled to 3X to assist interpretation of the shape differences.
