Biogeographic map

[Dora Julieth Chávarro]

Hello,
I am doing a biogeographical research and now that I have the results I need to make a dispersion map similar to the one in the following image. How can I make an image like this? 

Thank you very much for your help.

Hi!  The map is totally independent from BioGeoBEARS.  You can do such maps in R, with packages like maptools, sp, and rgdal.  The world map dataset is called "wrld_simpl".  However, coloring custom sections within that map requires making new shapefiles, this can be done but requires some GIS experience or a lot of googling.  For a one-off, it is probably easier to do it by hand in a graphics program.

For the BioGeoBEARS part, that looks like a phylogeny with per-area probabilities plotted, see eg:

I would do the phylogeny & area colors first, then at the end make your map with colors to match.

Cheers!

Nick
