The edge of neutral evolution in social dilemmas
Jonas Cremer, Tobias Reichenbach, Erwin Frey
The functioning of animal as well as human societies fundamentally relies on cooperation. Yet, defection is often favorable for the selfish individual, and social dilemmas arise. S…
Zero-one survival behavior of cyclically competing species
Maximilian Berr, Tobias Reichenbach, Martin Schottenloher +1
Coexistence of competing species is, due to unavoidable fluctuations, always transient. In this Letter, we investigate the ultimate survival probabilities characterizing different…
Instability of spatial patterns and its ambiguous impact on species diversity
Tobias Reichenbach, Erwin Frey
Self-arrangement of individuals into spatial patterns often accompanies and promotes species diversity in ecological systems. Here, we investigate pattern formation arising from cy…
Self-Organization of Mobile Populations in Cyclic Competition
Tobias Reichenbach, Mauro Mobilia, Erwin Frey
The formation of out-of-equilibrium patterns is a characteristic feature of spatially-extended, biodiverse, ecological systems. Intriguing examples are provided by cyclic competiti…
Noise and Correlations in a Spatial Population Model with Cyclic Competition
Tobias Reichenbach, Mauro Mobilia, Erwin Frey
Noise and spatial degrees of freedom characterize most ecosystems. Some aspects of their influence on the coevolution of populations with cyclic interspecies competition have been…
Anomalous finite-size effects in the Battle of the Sexes
Jonas Cremer, Tobias Reichenbach, Erwin Frey
The Battle of the Sexes describes asymmetric conflicts in mating behavior of males and females. Males can be philanderer or faithful, while females are either fast or coy, leading…
