Significant single-predictor Generalized Linear Model (GLM) and Spatial Linear Model (SLM) for species richness.

<p>Actual <i>R</i>² and pseudo-<i>R</i>² values can be found in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0056245#pone.0056245.s017" target="_blank">Table S4</a>. The predictors are shallow water area (SW), coastline length (CL), habitat diversity based on area (HDIa), habitat diversity based on number of patches (HDIn), sea surface temperature (SST), and net primary productivity (NPP). Asterisks indicate significance value of P:</p>*<p>(<0.05),</p>**<p>(<0.01);</p>***<p>(<0.001); ns (not significant).</p><p>Grid sizes are as follows: Small = 23,000 km²; Medium = 92,000 km²; Large = 368,000 km²; UTM = 617,000 km²; Extra large = 1,470,000 km²; Largest = 5,100,000 km². The significance value with the highest adjusted <i>R²</i> and pseudo-<i>R²</i> is highlighted in boldface.
