S1 Detailed technical information: calculation of the TPI
The Topographic Position Index (TPI, Weiss 2001), a measure of local topographic variation, was calculated as the difference between the elevation of the focal pixel and the average elevation of all surrounding pixels within a pre-determined radius (here: 25 m). Pixels with large absolute TPI values (larger than the SD value of the TPI layer, following Weiss 2001) were categorized as being positioned in a depression (negative values) or on a ridge (positive values) while pixels with small absolute TPI values were categorized as belonging to slopes. We used slope values to distinguish between pixels located on a steep slope when their slope angle exceeded 34 degrees, as this corresponds to the maximum inclination where agriculture is practiced within the TNP (sanabria siles et al. 2012) or on a gentle slope if otherwise. The proportion of pixels in a patch belonging to each of these four categories (i.e., depression, ridge, steep slope, gentle slope) was used as indicator for local topographic variation.

Variable AICw Coefficient SE
Akaike’s Information Criterion weights (AICW), values of the coefficient and standard errors (SE) of the variables included in the Generalized Linear Mixed Models analysis with Chao2 and ICE total species richness estimates at watershed and patch levels. Variables with AICW > 0.50 are shown in bold.
* indicates variables which have a coefficient value being larger than their standard errors.
