From: Resource supply and the evolution of public-goods cooperation in bacteria
The cost of cooperation decreases with increasing resource supply. Bars represent mean + SE fitness of WS relative to SM after 24 hours of competition in shaken microcosms where the WS phenotype is purely costly due to the prevention of biofilm formation. These data show that the fitness of the cooperative WS phenotype relative to the SM phenotype increases with increasing resource supply.
