Title: "The evolution of human diet in southeastern South America through stable isotopes"

Speaker: Andre Carlo Colonese, researcher at ICTA-UAB and Departament of Prehistory

Date: Friday, 27th January, 2023
Time: 3pm
Venue: Online - Zoom 


The traditional ecological knowledge of small-scale fisheries plays a prominent role in current debates and policies concerning sustainable fisheries and biodiversity, yet these fisheries and their actors are historically invisible in most tropical and subtropical regions. I will present the ERC project TRADITION and its multidisciplinary research strategy on the evolution of fisheries along the southern coast of Brazil. This region has supported coastal populations for the past 6000 years, through periods of environmental and social changes. The project brings together biomolecular and zooarchaeological analyses of archaeological records, along with the analysis of historical documents and modern coastal communities. In particular, I will discuss the challenges and opportunities of stable isotope analysis of skeletal remains (δ13C, δ15N) to reconstruct the role of marine fish protein to pre-colonial, post-contact and modern populations. The results reveal how collaborative research efforts between archaeologists, historians, and marine ecologists can productively advance our understanding of past coastal ecosystems and contribute to conservation debates.
