Location of the 29 islands surveyed.

<p>Color scale indicates oceanic net primary production derived from satellite data using the Vertically Generalized Production Model (VGPM). Circles indicate the relative NCEAS cumulative human impact score for each island.

Survey data and calculated values for 29 islands in the Pacific, grouped by region.

<p>Predicted metabolic rates are basal rates. NPP = net primary production. Colors identify each island group in the figures.</p

Microbialization scores plotted against the combined fish + microbes predicted metabolic rates for each of the 29 islands surveyed.

<p>Colors are as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0043233#pone-0043233-g002" target="_blank">Fig. 2</a>.

Linear regression analysis of microbialization scores versus NCEAS cumulative human impact values (y = 8.19 x – 26.10; r² = 0.68).

<p>The microbialization score is the percentage of the combined fish and microbial predicted metabolic rate that is microbial. Color denotes oceanographic region: Guam and the Mariana Islands (orange circles), the Main Hawaiian Islands (blue circles), Pacific Remote Islands and Atolls (pink circles), and the Samoa region (green circles).
