  1. Variables are referenced as follows: Abund, abundance (number of individuals per point); shrubarea, area of shrubland in the buffer around the plot (ha); forarea, area of forest in the buffer around the plot (ha); elev, elevation at the plot (m); typecover, vegetation cover type following Edwards (1983); slope, slope at the plot (%); leaflitter, average leaf litter depth at the plot measured at each quadrant (cm); edge, edge index in the buffer around the plot (m); humaveg, average relative humidity; zone, zone (1, 2, or 3).
