The model is a stylised abstraction of the Yamana society, which inhabited the channels and islands of the southernmost part of Tierra del Fuego (Argentina-Chile). According to ethnographic sources, the Yamana developed cooperative behaviour supported by an indirect reciprocity mechanism: whenever someone found an extraordinary confluence of resources, such as a beached whale, they would use smoke signals to announce their find, bringing people together to share food and exchange different types of social capital. The model provides insight on how the spatial concentration of beachings and agents’ movements in the space can influence cooperation. We conclude that the emergence of informal and dynamic communities that operate as a vigilance network preserves cooperation and makes defection very costly. 2016-01-26 2016-01-26 2015-04 info:eu-repo/semantics/article 1932-6203 http://hdl.handle.net/10259/3910 10.1371/journal.pone.0121888 eng PLOS ONE. 2015, V. 10, n. 4, e0121888 info:eu-repo/grantAgreement/MICINN/CSD2010-00034 info:eu-repo/grantAgreement/MICINN/HAR2009-06996 info:eu-repo/grantAgreement/JCyL/GREX251-2009 info:eu-repo/grantAgreement/Argentine CONICET/PIP-0706 http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Attribution 4.0 International Public Library Science
