DESCRIPTION:\n	A central question in theoretical population biology is whe
 ther spatial ecological heterogeneity helps or hinders the evolutionary su
 ccess of mutants. Here I present a unified framework for selection on latt
 ice graphs with arbitrary environmental heterogeneity\, spanning two regim
 es: constant selection and frequency-dependent evolutionary games. In the 
 first part\, I calculate the fixation probability of advantageous mutants.
  I observe that the genotype specificity of the environment determines whe
 ther heterogeneity amplifies or suppresses selection\, while spatial corre
 lation in environmental states acts as a secondary determinant of its magn
 itude. In the second part\, I extend the framework to the evolution of coo
 peration under spatially varying payoffs\, where spatial correlation becom
 es the primary determinant\, predicting both the fixation probability of c
 ooperators and the timescales of selection. I discuss applications to the 
 evolution of drug resistance\, cooperation in microbial communities\, and 
 somatic evolution in epithelial tissues.\n\n//indico.ictp.it/event/11384/
