Resumen:
Many organisms?notably microbes?are embedded within complex communities where cooperative behaviors in the form ofexcreted public goods can benefit other species. Under such circumstances, intraspecific interactions are likely to be less importantin driving the evolution of cooperation. We first illustrate this idea with a simple theoretical model, showing that relatedness?theextent to which individuals with the same cooperative alleles interact with each other?has a reduced impact on the evolutionof cooperation when public goods are shared between species. We test this empirically using strain ofPseudomonas aeruginosathat vary in their production of metal-chelating siderophores in copper contaminated compost (an interspecific public good). Weshow that nonsiderophore producers grow poorly relative to producers under high relatedness, but this cost can be alleviated bythe presence of the isogenic producer (low relatedness) and/or the compost microbial community. Hence, relatedness can becomeunimportant when public goods provide interspecific benefits
