Data and code from: Spatial storage effect facilitates evolutionary rescue in rapidly changing environments

The storage effect is a plausible natural mechanism that generates balanced genetic polymorphism in temporally varying environments. Balanced polymorphism may facilitate evolutionary rescue, promoting the persistence of populations otherwise destined for extinction. However, it is unknown whether the storage effect can be established in small populations whose size is allowed to vary, and if so, whether it will lead to evolutionary rescue. In this study, we investigate whether the spatial storage effect emerges and facilitates evolutionary rescue across small populations of variable sizes that inhabit heterogeneous, temporally varying environments and exchange migrants. We use an eco-evolutionary model to examine the phenomenon under a wide set of conditions, including the magnitudes and periods of temporal variation, habitat harshness, migration rates, the degrees of spatial heterogeneity, and increasing fitness oscillations over time, all within the framework of the logistic populatio..., , # Data and code from: Spatial storage effect facilitates evolutionary rescue in rapidly changing environments

## Description of the data and file structure

This package contains C programs used to generate the selection coefficients to mimic varying selection, tra.c, (developed by Gulisija and Kim 2015) and forward-in-time eco-evolutionary dynamics involving the spatial storage effect in temporally varying habitats (PRE.c), used in Rowland and Gulisija. 2025. Spatial Storage Effect Facilitates Evolutionary Rescue in Rapidly Changing Environments.

To run, please compile using:

gcc -Wall 'exe_file' -o 'program.c' -lm , or
