Point pattern analysis of the morphospace occupation pattern seen in <b>Figure 1</b>.

<p>A. Kernel density plot. Three hotspots at the extreme left (hypercarnivores, mostly Felidae), top (long-snouted, full premolar rows, mostly Canidae), and intermediate (Viverridae, Herpestidae, Mustelidae) are clearly in evidence. B. Ripley's K analysis of the patterns seen in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0057944#pone-0057944-g002" target="_blank">Figure 2A</a>. The x-axis represents inter-point distances, the y-axis the K-value. The dotted lines are the 95% confidence envelope of complete spatial randomness (CSR), while the solid line shows the actual values obtained. Values above the confidence envelope indicate significant attraction between points; values below it indicate significant repulsion between points. In the present case there is significant attraction at all distances.
