Evolutionary Game Theory and Cooperation

Successful strategies in the voluntarily repeated Prisoner's Dilemma

This paper analyzes the repeated Prisoner's Dilemma with strategies that allow leaving partners, showing higher cooperation and replacement of classical strategies with those that sanction cheaters by leaving.

The evolution of socially modulated dispersal

This study investigates the evolutionary drivers and consequences of socially modulated dispersal, identifying three stable outcomes and conditions under which social modulation can be favoured.

Cooperation, privatization and cheating in microbial exoenzyme synthesis: theoretical analysis in view of biotechnological applications

This paper develops a mathematical framework to analyze microbial strategies in exoenzyme synthesis, showing how cooperation, privatization, and cheating affect population dynamics and coexistence.

Interaction range of common goods shapes Black Queen dynamics beyond the cheater-cooperator narrative

This paper presents an eco-evolutionary model showing that Black Queen dynamics can lead to either distributed or centralized common good production, depending on the interaction range among ecotypes.

Group size dependent selection for cooperation versus freeloading in collective chemical defence

The paper shows that cooperation in chemical defense is more beneficial in smaller groups, while freeloaders have higher fitness in larger groups of pine sawfly larvae.

Direct and indirect benefits of cooperation in collective defense against predation

This study shows that cooperative defense in pine sawfly larvae provides both direct and indirect benefits, with individuals adjusting their contributions based on social context.

The key role of cheaters in the persistence of cooperation

This paper shows that cheaters can promote cooperation by enabling group survival in a multi-level selection model, challenging the classical view that cheaters destabilize cooperation.

Chimeric aggregative multicellularity in absence of kin discrimination

The paper investigates kin discrimination in Myxococcus xanthus, showing that the type VI secretion system (T6SS) mediates antagonism between distantly related strains, preventing chimeric fruiting body formation.

Phase separation and coexistence in spatial coordination games between microbes

This paper shows that spatial coordination games between microbes lead to phase separation and coexistence, with universal scaling consistent with experimental observations.

Emergence of alternative offspring care patterns from the evolution of parental negotiation strategies

This study uses individual-based simulations to show that parental negotiation strategies can lead to four alternative care patterns, including effective cooperation based on tit-for-tat rather than compensation.

The genetical evolution of social preferences: where the categorical imperatives of Hamilton, Kant and Nash meet

The paper models how social preferences evolve genetically, showing that Nash equilibria and inclusive fitness emerge as uninvadable strategies in pairwise interactions.

From friend to foe and back - Coevolutionary transitions in the mutualism-antagonism continuum

The paper models coevolutionary transitions between mutualism and antagonism, showing ecological changes can trigger bidirectional shifts and identifying a tipping point for mutualism breakdown.

Phase transitions and symmetry breaking of cooperation on lattices

This paper studies cooperation dynamics in a donation game with separated interaction and competition neighborhoods, finding symmetry breaking and phase transitions under different cost-to-benefit ratios.

A complex adaptive systems model of labor reciprocity and normative reasoning in swidden agriculture

The paper develops a complex adaptive systems model of swidden agriculture showing that sustainable high-intensity swidden emerges from balanced labor reciprocity and normative reasoning.

Positive and negative selective assortment in pairwise interactions

The paper analyzes how selective assortment in partner choice affects evolutionary dynamics and equilibria in populations playing different games.

Power asymmetry destabilizes reciprocal cooperation in social dilemmas

This study shows power asymmetry reduces cooperation in social dilemmas, with different effects in prisoners' dilemma and snowdrift game.

Reconciling ecology and evolutionary game theory or When not to think cooperation

This paper critiques the assumption in evolutionary game theory that all individuals have equal intrinsic growth rates, highlighting its limitations and suggesting a reconciliation with ecology.

Kin-discriminating partner choice promotes the evolution of helping

This study shows that kin discrimination in partner choice increases overall helping behavior compared to indiscriminate helping.

Strong segregation promotes self-destructive cooperation

The paper shows that self-destructive cooperation can persist under strong segregation by using engineered bacteria and automated experiments.

Evolution of cooperation in multichannel games on multiplex networks

The paper studies cooperation in multichannel games on multiplex networks, finding that network structure and strategy linking enhance cooperation rates when layers are structurally similar and perception errors are low.

Replicator dynamics generalized for evolutionary matrix games under time constraints

This paper generalizes replicator dynamics for evolutionary matrix games under time constraints, showing that the classical relationship between ESS and stability holds in any dimension with the new dynamics.

The general version of Hamilton's rule

The paper constructs a general version of Hamilton's rule to resolve debates about its generality by showing it can describe various social behaviors and fitness dependencies.

On Long-Term Species Coexistence in Five-Species Evolutionary Spatial Cyclic Games with Ablated and Non-Ablated Dominance Networks

The paper replicates and refutes findings from a previous study on species coexistence in spatial cyclic games, showing that longer simulation runs reveal different asymptotic behaviors and that ablations primarily affect convergence time.

Survival cost sharing among altruistic full siblings in Mendelian population

The paper analyzes the evolutionary stability of altruism in sibling interactions under starvation, showing that Hamilton's rule is sufficient for altruism but not necessary for its stability.

Evolutionary branching in multi-level selection models

This study examines evolutionary dynamics in multi-level selection models, showing that weaker individual-level selection promotes group-level diversification while stronger selection enhances group adaptation.

Spontaneous symmetry breaking of cooperation between species

The paper studies cooperation between species using a spatial prisoners dilemma model, showing four dynamical domains and spontaneous symmetry breaking in cooperation.

Optogenetic spatial patterning of cooperation in yeast populations

This paper uses optogenetics to control cooperation and cheating in yeast populations, showing that cooperation is most effective when cooperator domain size is constrained between two length-scales.

Higher-order effects, continuous species interactions, and trait evolution shape microbial spatial dynamics

The paper models microbial community dynamics using a continuous trait space framework, finding that mutation size and mobility best explain diversity patterns, and community formation time influences diversity profiles.

Shearing in flow environment promotes evolution of social behavior in microbial populations

The paper shows that flow shear promotes social behavior in microbial populations by limiting cheating strain spread and enhancing cooperativity.
