Dataset for manuscript: Heterogeneous environments shape invader impacts: integrating environmental, structural and functional effects by isoscapes and remote sensing

This dataset comprises:

(1) shape files of Acacia longifolia and Corema album which were used to fit the generalized additive mixed model (GAMM) to predict C. album foliar δ15N
(2) raster data used for predictive isoscapes at five study sites
(3) the R code used to fit the GAMM and examples how the predictive isoscapes were generated
(4) an R Workspace containing the shape files and raster data to be used with (3)

Please find a detailed description of the methods in our manuscript "Heterogeneous environments shape invader impacts: integrating environmental, structural and functional effects by isoscapes and remote sensing".
