Resumo Sob a direção de Clemente Onelli (1904-1924), o Jardín Zoológico de Buenos Aires se tornou uma importante atração pública e ganhou reputação internacional por suas inovações no abrigo e fornecimento de fauna latinoamericana. Era uma instituição híbrida que combinava instrução pública, pesquisa zoológica e aclimatação de animais úteis, sendo também símbolo de orgulho nacional. Apesar da localização geográfica aparentemente periférica, a instituição estava fortemente integrada na rede global de jardins zoológicos. O artigo utiliza a perspectiva transnacional para lançar luz sobre as muitas trocas multidirecionais de animais e conhecimento entre o Jardín Zoológico de Buenos Aires e as metrópoles do Norte.

Abstract Under the directorship of Clemente Onelli (1904-1924), the Jardín Zoológico de Buenos Aires became a major public attraction and gained an international reputation for its innovations in animal keeping and as a supplier of Latin American fauna. It was a hybrid institution that combined the tasks of public instruction, zoological research, and acclimatization of useful animals, and also served as a symbol of national pride. Despite its seemingly peripheral geographical location, the institution was firmly integrated in the global network of zoological gardens. This paper utilizes a transnational perspective to tease out the numerous, multidirectional exchanges of animals and knowledge between the Jardín Zoológico de Buenos Aires and Northern metropolises.

Eudald Carbonell is mainly known for being the co-director of the Atapuerca research project, a hominid site in Northern Spain that boasts the "oldest European". In the course of his career as an archaeologist, he has become a highly visible figure, not least because of his incessant attempts to communicate his ideas to the general public. In these past four decades, Carbonell has taken on a host of diverse roles: scientific but also social and political ones. The political and scientific context of Catalonia and Spain since the early 1970s proves crucial in these activities. Carbonell's claim to belong to a "peripheral" scientific community (be it Catalan or Spanish) is a central element in the construction of these roles. At the same time, Carbonell provides an instructive example of the "medialization" of science, transforming himself from an outsider into a celebrity and ultimately into a commodity.
