  1. Note that the island of New Guinea is excluded from the data analysis in this table because of its great size which skews the analysis
  2. aThis group is comprised mostly of the Galapagos islands, politically part of Ecuador
  3. bAverage island areas for these atoll countries are overestimates as they are based on polygons that subsume multiple islands (see text)
  4. cNote that the large island of New Guinea is excluded from this analysis because it is shared between Papua New Guinea and Indonesia
