Figure 1: Left hand panels show maps of study site locations (triangles) along the elevational gradients on both islands. Dashed line on Hispaniola separates the North paleoisland, from the south paleoisland—locations that have had separate evolutionary histories during periods of higher sea levels, and which have different species pools. Note that maps of Jamaica and Hispaniola are not on same scale. Right hand panel illustrates the total area (y-axis on log scale) in 200m elevational bands on both islands. Note the steep drop off in area on Jamaica above 700m.
