I have been searching a lot but I didn't find any useful solution yet. I have a shapefile representing range polygons for different species of primates and rasters representing current and future environmental conditions or predictors. What I would like to do is to assess for each species if there is any difference when subtracting future - present rasters of each predictor within species range. I have been trying to do this in ArcGIS 10.5 by extracting all predictors using primate shapefile as a mask, using raster calculation and reclassify tools, but it came up with results for primates and not for each primate species.
Any suggestion about how to do this in ArcGIS?
I am a bit familiar with R (more than ArcGIS), so if any script/package is available to do this in R I don't mind to give it a try too.
