Replacers and their evolutionary stability in the Moran process on graphs
Michal Pecho, Jakub Svoboda, Lenka Kopfová +2
Evolutionary dynamics in finite structured populations are commonly modeled by the Moran Birth-death process. A key quantity is the fixation probability of a single invader attempt…
Genotype specificity and spatial arrangement govern the direction and magnitude of selection in variable environments
Hossein Nemati, Kamran Kaveh, Jakub Svoboda +2
Spatial environmental variation can either amplify or suppress the fixation of beneficial mutants in structured populations, yet the interplay of ecological factors and spatial str…
Predicting success of cooperators across arbitrary heterogeneous environmental landscapes
Amir Kargaran, Kamran Kaveh, Krishnendu Chatterjee
Cooperation is central to the organization of complex biological and social systems. Most theoretical models assume homogeneous environments; in reality, populations inhabit spatia…
Maintaining diversity in structured populations
David A. Brewster, Jakub Svoboda, Dylan Roscow +3
We examine population structures for their ability to maintain diversity in neutral evolution. We use the general framework of evolutionary graph theory and consider birth-death (b…
Amplifiers of selection for the Moran process with both Birth-death and death-Birth updating
Jakub Svoboda, Soham Joshi, Josef Tkadlec +1
Populations evolve by accumulating advantageous mutations. Every population has some spatial structure that can be modeled by an underlying network. The network then influences the…
