A Ross-Gillespie, A Gardner, A Buckling, SA West… - …, 2009 - academic.oup.com
Although cooperative systems can persist in nature despite the potential for exploitation by
noncooperators, it is often observed that small changes in population demography can tip …

Frequency dependence and cooperation: theory and a test with bacteria

A Ross-Gillespie, A Gardner, SA West… - The American …, 2007 - journals.uchicago.edu
Hamilton's inclusive fitness theory provides a leading explanation for the problem of
cooperation. A general result from inclusive fitness theory is that, except under restrictive …

Repression of competition favours cooperation: experimental evidence from bacteria

R Kümmerli, P Van Den Berg, AS Griffin… - Journal of …, 2010 - academic.oup.com
Repression of competition (RC) within social groups has been suggested as a key
mechanism driving the evolution of cooperation, because it aligns the individual's proximate …

R Kümmerli, A Gardner, SA West, AS Griffin - Evolution, 2009 - academic.oup.com
Numerous theoretical studies have investigated how limited dispersal may provide an
explanation for the evolution of cooperation, by leading to interactions between relatives …

Maintenance of microbial cooperation mediated by public goods in single-and multiple-trait scenarios

Ö Özkaya, KB Xavier, F Dionisio… - Journal of …, 2017 - Am Soc Microbiol
Microbes often form densely populated communities, which favor competitive and
cooperative interactions. Cooperation among bacteria often occurs through the production of …

Dynamic social behaviour in a bacterium: Pseudomonas aeruginosa partially compensates for siderophore loss to cheats

F Harrison - Journal of evolutionary biology, 2013 - academic.oup.com
Cooperation underlies diverse phenomena including the origins of multicellular life, human
behaviour in economic markets and the mechanisms by which pathogenic bacteria cause …

Nutrient limitation determines the fitness of cheaters in bacterial siderophore cooperation

DJ Sexton, M Schuster - Nature communications, 2017 - nature.com
Cooperative behaviors provide a collective benefit, but are considered costly for the
individual. Here, we report that these costs vary dramatically in different contexts and have …

Molecular and regulatory properties of a public good shape the evolution of cooperation

R Kümmerli, SP Brown - Proceedings of the National …, 2010 - National Acad Sciences

to humans. Although previous research focused on the behavioral and ecological conditions …

Adaptation to public goods cheats in Pseudomonas aeruginosa

S O'Brien, AM Luján, S Paterson… - Proceedings of the …, 2017 - royalsocietypublishing.org
Cooperation in nature is ubiquitous, but is susceptible to social cheats who pay little or no
cost of cooperation yet reap the benefits. The effect such cheats have on reducing …

Cheating on cheaters stabilizes cooperation in Pseudomonas aeruginosa

Ö Özkaya, R Balbontín, I Gordo, KB Xavier - Current Biology, 2018 - cell.com
Bacterial cooperation can be disrupted by non-producers that can profit from public goods
without paying their production cost. A cheater can increase in frequency, exhausting the …
