Warrens <i>I</i> niche overlap metric per EMIP.

<p>The upper diagonal shows the variation in niche overlap using circle size and color (low overlap is shaded green; high overlap is shaded red; extent of overlap is indicated by dot size and red or green color saturation). The lower diagonal gives the actual overlap metric as colored by the scaling graphic. EMIP species names are here represented by both the complete scientific Latin name (y-axis) and its coded counterpart (upper x-axis) as defined in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0095427#pone-0095427-t001" target="_blank">Table 1</a>. All insignificant (p>0.05) niche overlap metrics, as derived from a niche equivalency test, are indicated with an “X”.
