Note:
*indicates strong or robust impact, that is 95% confidence intervals as defined by ±1.96×SE not overlapping 0; italic indicates opposite from a priori prediction. AltDEM = altitude; Precip = precipitation; Dtwater = distance to freshwater; dtfedge07 = distance to forest edge; dtpacr = distance to centroid of protected areas; Dtmprd = distance to major public road;dtf05cr = Distance to nearest centroid of forest block greater than 50,000 ha.
