Landscape predictors of rodent dynamics in fragmented rainforests

Data on rodent species abundance (Oryzomys sp., Heteromys desmarestianus, Sigmodon hispidus and Peromyscus mexicanus) was obtained in 12 forest sites in the fragmented Lacandona rainforest. We obtained the correlation coefficients (Spearman), i.e., how population abundance relates to year (2011, 2012, 2014 and 2016) and related this with differences across time (2016-2010) in landscape structure (i.e., percentage of forest cover, matrix contrast, number of forest patches, forest edge density, and mean inter-patch distance) surrounding each site. Landscape metrics were measured across different landscape sizes (range of radii = 200 to 1400 m, at 200-m intervals).
