The maintenance of “public” or “common good” producers is a major question in the evolution of cooperation. Because nonproducers benefit from the shared resource without bearing its cost of production, they may proliferate faster than producers. We established a synthetic microbial system consisting of two Escherichia coli strains of common-good producers and nonproducers. Depending on the population structure, which was varied by forming groups with different initial compositions, an… 

Cooperation and Hamilton's rule in a simple synthetic microbial system

A simple synthetic microbial system of producers and nonproducers of an extracellular growth‐enhancing molecule, which acts as a ‘common good’ is used, which is uniquely suited for studying the relation between the parameters entering Hamilton's rule and the quantities governing the systems’ behavior.

The emergence of cooperation from a single mutant during microbial life cycles

Two evolutionary mechanisms favouring cooperative behaviour are analyzed and it is found that population bottlenecks followed by exponential growth phases strongly increase the survival and fixation probabilities of a single cooperator in a free-riding population.

Eco-evolutionary feedbacks can rescue cooperation in microbial populations

It is shown that the demographic collapse induced by cheaters in the population can actually contribute to the rescue of cooperation, in a clear illustration of how ecology and evolution can influence each other.

Growth dynamics and the evolution of cooperation in microbial populations

Frequency and size of population bottlenecks, and growth dynamics, are found to be the major ecological factors determining the regimes and thereby the evolutionary pathway towards cooperation.

Homogeneous and Heterogeneous Response of Quorum-Sensing Bacteria in an Evolutionary Context.

This work finds that the optimal total PG production of the QS population mainly depends on the shape of the benefit, which contradicts the usual interpretation of QS as a mechanism to establish a uniform, synchronized response of a bacterial population.

Public good dynamics drive evolution of iron acquisition strategies in natural bacterioplankton populations

It is shown that public good games drive the evolution of iron acquisition strategies in wild populations of marine bacteria and using ecological data of resource partitioning, cheating coevolves with the ecological specialization toward association with larger particles in the water column, suggesting that these can harbor stable enough communities for dependencies among organisms to evolve.

An Environment-Sensitive Synthetic Microbial Ecosystem

This research designed, simulated and constructed a synthetic ecosystem where various population dynamics formed by changing environmental factors such as extinction, obligatory mutualism, facultative mutualism and commensalism and may act as a chassis for construction of more complex microbial ecosystems.

Density-dependent private benefit leads to bacterial mutualism

It is shown that the applied population structure supports cooperation in general, which, depending on the level of private benefit and intensity of mixing helps either the specialist or the generalist cooperators.

Cooperation and the Fate of Microbial Societies

Examination of the competition between cooperating and “cheating” strains of yeast finds that, depending on the initial mix of strains, this yeast society either evolves toward a stable coexistence or collapses for lack of cooperation.

Synthetic cooperation in engineered yeast populations

This work reports the construction of a synthetic obligatory cooperative system, termed CoSMO (cooperation that is synthetic and mutually obligatory), which consists of a pair of nonmating yeast strains, each supplying an essential metabolites to the other strain.

A synthetic Escherichia coli predator–prey ecosystem

A synthetic ecosystem consisting of two Escherichia coli populations, which communicate bi‐directionally through quorum sensing and regulate each other's gene expression and survival via engineered gene circuits is constructed, which resembles canonical predator–prey systems in terms of logic and dynamics.

Cooperation and conflict in quorum-sensing bacterial populations

This work examines the social evolution of QS experimentally in the opportunistic pathogen Pseudomonas aeruginosa, and shows that although QS can provide a benefit at the group level, exploitative individuals can avoid the cost of producing the QS signal or of performing the cooperative behaviour that is coordinated by QS, and can therefore spread.

Cooperation and competition in pathogenic bacteria

The results show that higher levels of cooperative siderophore production evolve in the higher relatedness treatments, but that more local competition selects for lower levels of siderophile production, and that there is a significant interaction between relatedness and the scale of competition.

Multicellular behavior in bacteria: communication, cooperation, competition and cheating.

The significance of two recent studies of the phenomenon of "cheating" mutants and their exploitation of cooperating microbial populations of Pseudomonas aeruginosa are discussed.

Local migration promotes competitive restraint in a host–pathogen 'tragedy of the commons'

It is shown that the migration pattern affects both coexistence and evolution within a community of bacterial hosts and viral pathogens distributed across a large network of subpopulations, and can determine whether a de novo tragedy of the commons is resolved in favour of restraint.

Communication in bacteria: an ecological and evolutionary perspective

It is shown that the nature of interactions through quorum-sensing chemicals does not simply involve cooperative signals, but entails other interactions such as cues and chemical manipulations that might have a role in conflicts within and between species.

Single-Gene Greenbeard Effects in the Social Amoeba Dictyostelium discoideum

The csA gene inDictyostelium discoideum acts as a single-gene greenbeard, and when wild-type cells are mixed with csA-knockout cells, the wild type is more altruistic, but is also able preferentially to direct the benefits to other wild- type cells.

Synthetic ecosystems based on airborne inter- and intrakingdom communication

Using multistep airborne communication and signal transduction, synthetic ecosystems within a mammalian cell population, in mice, or across species and kingdoms are presented that mimic fundamental coexistence patterns in nature, including symbiosis, parasitism, and oscillating predator–prey interactions.
