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

README for POPS_predictionfile.txt

Other POPS infiles are POPS_input.txt and POPS_geo_dist_circle.

This file contains climate prediction data for each of the individuals/sample sites in the core population set, in the year 2050. This file was used as input for the POPS prediction utility.

Note that the text file was created in Windows 8.1.

The first row contains self-explanatory headers indicating the contents of their respective columns. The subsequent rows contain predicted climate data and spatial data for each individual.

Column 1: Individual identifiers

All individuals are identified by the three letter population code given in Table S1, supporting information file [available at http://onlinelibrary.wiley.com/journal/10.1111/%28ISSN%291365-294X] 
followed by a number, e.g. ALS1.

Column 2: PC1_precipitation_2050

The position of each individual along the first principal component axis, which is a precipitation gradient, in the predicted climate space in the year 2050.  
All individuals from the same population have the same position.

Column 3: PC2_temperature_2050

The position of each individual along the second principal component axis, which is a precipitation gradient, in the predicted climate space in the year 2050. 
All individuals from the same population have the same position.

Columns  4 & 5: Longitude and Latitude, respectively.

GPS coordinates of each sample site. These are the same ‘jittered’ coordinates from POPS_input.txt.
