Language diversity among Pacific islands will be positively associated with land area (959).


Of various response variables tested, the strongest correlation (land area) is recorded. Other variables without significant correlations include rainfall, elevation, absolute latitude, mean growing season, rainfall, number of ecoregions, continental dust fall, tephra, and island type. Other variables with significant correlations are settlement scale and distance to closest continent (see other hypothesis).
