  1. Variables are referenced as follows: Shrubland area, area of shrubland in the buffer around the plot (ha); Forest area, area of forest in the buffer around the plot (ha); Elevation, elevation at the plot (m); Typecover, vegetation cover type following Edwards (1983); Slope, slope at the plot (%); Leaf litter depth, average leaf litter depth at the plot measured at each quadrant (cm); Edge, edge index in the buffer around the plot (m); Relative humidity, average relative humidity; Zone, zone (1, 2, or 3).
