README: Data from: Sexual selection and mate limitation shape evolution of species’ range limits

https://doi.org/10.5061/dryad.2547d7wzz

The dataset contains simulation output presented in the article: Sexual selection and mate limitation shape evolution of species’ range limits.

Data includes two types of .txt files:

1. [Simulation Number]_Para.txt = Parameter files that specify parametrization of the model
2. [Simulation Number]_Pops.txt = Population files that contain demographic and trait variables

Variable names explained:

Parameter names follow the description in the parameters.h file located in the Related Works section.

a) _Para.txt files
