Maps of cumulative current within sampling site, modelled with circuit theory algorithm using Circuitscape 4.0, based on a land coverage layer of Costa Rica in 2005. Resistance values for each category are described on Supplementary Table S4. (a) corresponds to white-eared ground-sparrow (Melozone leucotis) sampling sites, and (b) house wren (Troglodytes aedon) sampling sites.
