Acácias e geografia histórica: rotas de um percurso global (parte1)
Manuel Miranda Fernandes
AbstractThe geographic transference of plants is a major driver of ecosystem and landscape transformation, thus contributing to global change processes. One of the best models to analyze the interactions between evolutionary, ecological and socioeconomic dimensions of plant transfers is represented by the genus Acacia. This paper focuses on human-mediated transference of Acacia species, from a historical geography perspective, in 2 parts. Part 1 addresses the transference routes of Australian species of Acacia, introduced in Portugal and SW Europe since the XIXth century. Part 2 focus on the transference and diffusion of A. farnesiana, a species of Mesoamerican origin, cultivated in Europe since the early XVIIth century. Conceptual and methodological aspects of this research are also presented, regarding the relation between Nature and Culture. This paper is a first synthesis of the current research on the phytogeographic origin, intercontinental transference and regional diffusion in Acacia.
