Characterising a Hybrid Zone between a Cryptic Species Pair of Freshwater Snails

README for climate_data.txt

This is the climate data used to construct the PCA axes. The data were downloaded from the WorldClim database for present day climate and for a 2xCO2 climate scenario in the year 2050
at the GPS cordinates of the core population set sample sites.

Note that the text file was created in Windows 8.1. The data has been formatted for use with the program PAST (http://palaeo-electronica.org/2001_1/past/issue1_01.htm).

The first row contains self-explanatory headers indicating the contents of their respective columns. 
Rows 2-26 contain predicted climate data for the year 2050 at each of the populations in the core population set (across the Pyrenees). 
Rows 27-51 contain climate data from the period 1950-2000 at these sites.
