The file contains the individual-based simulation code that is used in the paper "Population rescue through an increase of the selfing rate under pollen limitation: plasticity vs. evolution". This study built eco-evolutionary models and individual-based simulations to explore the demographic and genetic conditions in which higher self-fertilization by plasticity and/or evolution rescues populations, following deficits due to sudden onset of pollen limitation. The code is written in C++. Please first read the README.txt file for instructions and details.
