Supplement 1. Area estimates for each 100-m elevational band on each of the 32 mountains used in statistical analyses of species–area relationships along elevational gradients of mammals.

File List AreaData.txt Description The AreaData.txt file is a tab-separated ASCII file. The file contains the raw area estimates of each 100-m elevational band on each of the 32 globally distributed mountains used in statistical analyses of the species–area effect along elevational gradients in mammals. Two columns are included for each mountain (names of mountains in first line above first column per mountain): Elevation = Lower boundary of the 100-m elevational band (e.g., 0 indicates band from 0–99.9999) Area (m²) = Estimate of area of the 100-m elevational band in square meters based on calculation from digital elevation models in ArcGIS (see text for specifics). There are no missing values.
