Male bottlenose dolphins form persisting multi-level alliances. Second-order alliances of 4-14 males are the core social unit, within which 2-3 males form first-order alliances to sequester females during consortships. We compared social bond strength, relatedness and age similarity of potential and realised partners of individual males in two age periods: (i) adolescence, when second-order alliances are formed from all available associates, and (ii) adulthood, when first-order allies are selected from within second-order alliances. Social bond strength during adolescence predicted second-order alliance membership in adulthood. Moreover, males preferred same-aged or older males as second-order allies. Within second-order alliances, non-mating season social bond strength predicted first-order partner preferences during mating season consortships. Relatedness did not influence partner choice on either alliance level. There is thus a striking resemblance between male dolphins, chimpanzees and humans, where closely bonded non-relatives engage in higher-level, polyadic cooperative acts. To that end, our study extends the scope of taxa in which social bonds rather than kinship explain cooperation, providing the first evidence that such traits might have evolved independently in marine and terrestrial realms.</dcterms:abstract> <dspace:isPartOfCollection rdf:resource=""/> <dc:creator>Connor, Richard C</dc:creator> <dc:contributor>Krützen, Michael</dc:contributor> <dc:creator>Sherwin, William B.</dc:creator> <dcterms:rights rdf:resource=""/> <dc:creator>Willems, Erik P.</dc:creator> <dcterms:hasPart rdf:resource=""/> <dc:creator>Holmes, Kathryn G.</dc:creator> <dc:contributor>Connor, Richard C</dc:contributor> <dc:contributor>Gerber, Livia</dc:contributor> <dc:contributor>Wild, Sonja</dc:contributor> <dc:contributor>Wittwer, Samuel</dc:contributor> <dcterms:title>Cooperative partner choice in multi-level male dolphin alliances</dcterms:title> <dc:creator>King, Stephanie L.</dc:creator> <dcterms:isPartOf rdf:resource=""/> </rdf:Description> </rdf:RDF>
