Table 1.
Type of agricultural matrix surrounding the forest fragment, popular name of the fragment in the region, total size and geographic coordinate of sampled forest fragments.

Distance gradient in each system.
Each system has three replicates, with five pitfall traps for each place in the system (interior of agricultural matrix, edge of agricultural matrix, edge of forest fragment and interior of forest fragment).
Table 2.
Numbers of species of ants trapped in fragments and matrices at the various locations, and also the total species trapped when like-locations are combined.
(FF–forest fragment, AM–agricultural matrix).

Variations in ant species richness in the systems.

Non-metric dimensional scale plot.
NMDS for the systems (FF—forest fragment and AM—agricultural matrix). The black lines and numbers represent Jaccard’s similarity values.
Table 3.
Jaccard’s index of similarity among the systems.
(FF–forest fragment, AM–agricultural matrix). Numbers are rounded to three decimal places. The values range from 0 (not similar) to 1(totally similar). Diagonal values are the number of unique species for the locations. Upper diagonal shows the number of species that occur in both sites.
