Tropical rainforests are complex and varied environments found around the globe in tropical and subtropical regions. They hold a large biodiversity but also present multiple challenges, both for their human occupations and archaeological studies. In recent decades, we have learned that our ancestors lived in these environments much earlier than we thought and continuously over tens of thousands of years. Using stable isotope analyses, we hope to better understand how hunter-gatherers lived there in the past and if they perhaps gradually started using them differently before the introduction of agriculture.

Urbanization, forestry, and agriculture are readily associated with contemporary human land use, but how we use the land around us has changed greatly through our species' long history. The availability of food, seasonality, or the concentration of a particularly abundant rich food source are all examples of concerns that prehistoric populations would have faced, all of which would have been managed through land use strategies.
Directly and systematically assessing how past populations utilized their ecosystems, especially as far back as the Pleistocene, remains particularly challenging because pre-urban hunter-gatherer societies may not have left us with large-scale or significant traces. However, such studies are important to identify and assess drivers of long-term land changes and dynamics and to provide baselines for subsequent changes.
Dr. Nicolas Bourgon is carrying out zinc isotope analyses using a multi-collector mass spectrometer with inductively coupled plasma (MC-ICP-MS). The isotope analysis is carried out on fossil tooth enamel samples dissolved in acid from which the element zinc was previously separated using ion chromatography. The results obtained can help us distinguish between diets that rely more heavily on plants or meat, for example.

Using a systematic comparison of multi-isotopic data of δ66Zn, δ13C, and δ18O, we seek to quantify hunter-gatherers' dietary reliance on different resource types (e.g., plant, animal, and aquatic). Although the choice of food consumed may not have left visible traces in the landscape or the archeological records, these geochemical tracers can help us explore whether gradual dietary transitions were already underway even before the introduction of agriculture or animal husbandry.
This project is co-funded by an ongoing Walter Benjamin funding program of the Deutsche Forschungsgemeinschaft, with the project specifically looking into omnivory and how zinc isotopes can help us detect this dietary behaviour. This project is also being conducted in collaboration with the Bundesanstalt für Materialforschung und -prüfung (Berlin, Germany), the University of Sri Jayewardenepura (Gangodawila, Nugegoda, Sri Lanka), and the Australian National University (Canberra, Australia).
"Science and Responsibility" is the working title for a book project on the history of the life sciences in the Max Planck Society (MPG) between 1948 and 2002. The focus is on the agricultural sciences and molecular biology in the MPG and their different reactions to the social problems of their time. The contrasting development of these sciences…
This project explores humanity's evolving relationship with forests, examining how cultural, scientific, and technological advancements have shaped our interactions with natural resources over time. Emphasising the global impact of deforestation, which accounts for 11% of carbon emissions, it aims to foster transnational collaboration among…
By analyzing existing publications from the last three decades with methods from the framework of socio-epistemic networks, the project aims at uncovering the historical roots of the emergent science of Geoanthropology.
In order to deepen our understanding of human occupation history over the past 30,000 years of this dynamic region, we started the exploration of a number of human settlements and cave sites scattered in Armenia dating back from the Late Iron age all the way back to the Upper Palaeolithic.
The project emphasises global environmental justice and examines how resource extraction has unevenly affected regions worldwide, influencing economic, societal, and ecological dynamics. The project aims to understand historical decisions guiding energy extraction and transitions, fostering dialogue among scholars and stakeholders on climate…
This project explores changing epistemes among surveyors during Old Babylonian period, or the early second millennium BCE in Mesopotamia (ancient Iraq). It asks, “How and to what extend did knowledge change in this community?” “Who affected this change?” and “What impact did this change have on the surveyor’s themselves and on other communities?”
