Variation in American palm species richness locally explained by water and energy. L. EiserhardtWolf BjorholmStine SvenningJens-Christian F. RangelThiago BalslevHenrik 2011 <p>Local R<sup>2</sup> values obtained from geographically weighted regression (GWR) of palm species richness on annual precipitation, precipitation of the driest month, and water deficit (A) and mean annual temperature, minimum temperature of the coldest month, and potential evapotranspiration (B). Fraction of variation uniquely explained by the water variables (C) and energy variables (D) obtained from variation partitioning. The green circle in (A) shows the GWR bandwidth for a cell situated at the equator.</p>
