HERCA is an interdisciplinary group of scientists from several countries that seeks to understand the relationships between the emergence and demise of stratified societies, food procurement strategies, and environmental conditions in Pre-Columbian Amazonia. The HERCA project is co-led by Professor Frank Mayle, funded by AHRC (UK), and Professor Eduardo Goés Neves, funded by FAPESP (Sao Paulo Research Foundation, Brazil).
Uncertainty about Amazonia’s past human-environment relations stems from a paucity of archaeological data and a lack of interdisciplinary collaboration essential for the investigation of human-environment interactions. HERCA capitalises on the timely opportunity for collaborative research provided by the AHRC-FAPESP MoU to assemble an international team of investigators and project partners from UK, European, Brazilian, and Bolivian institutions to address our overall aim: to determine the relationships between the emergence and demise of stratified societies, food procurement strategies, and environmental conditions in Pre-Columbian Amazonia.
I am a tropical palaeoecologist interested in the long-term dynamics and interactions between South American tropical ecosystems, climate change, and human land use over past centennial to multi-millennial timescales. My lab specialises in the analysis of fossil pollen, charcoal, and phytoliths from radiocarbon-dated lake/bog sediments and soils to reconstruct past environmental change. My first coring expedition to South America was in 1995 in a remote, but spectacular, corner of Amazonian Bolivia – Noel Kempff Mercado National Park – which sparked my long-term interest in Quaternary/Holocene forest-savanna dynamics. Since then, I have been fortunate enough to expand my fieldwork across Bolivia and Brazil – primarily in Amazonia, but also Brazil’s Atlantic Forest – via strong collaborative links with universities and museums in both these countries. Understanding past human-environment interactions requires an inter-disciplinary approach, so I collaborate closely with botanists, archaeologists, geomorphologists, and palaeoclimatologists. My research has been funded by NERC, AHRC, and The Leverhulme Trust in the UK, as well as FAPESP and CNPq in Brazil, and National Geographic in the US. Currently, I am co-leader of the HERCA project – ‘Human-Environment Relationships in pre-Columbian Amazonia’ – with Eduardo Neves (USP, Brazil), jointly funded by the AHRC and FAPESP (Sao Paulo, Brazil), 2019 – 2022.
Eduardo G. Neves (Co-PI)
I have a B.A. in History from the University of São Paulo and a PhD in Archaeology from Indiana University, in the United States. I am the Director of the Laboratory of Tropical Archaeology (ARQUEOTROP) at the Museum of Archaeology at the University of São Paulo. From 2009 to 2011, I was President of the Brazilian Archaeological Society. I am also a member of numerous international boards in archaeology and anthropology, including the board of the Wenner-Gren Foundation.
My main area of research is southwestern Amazonia, at the current border of Bolivia and Brazil, where I have been studying middle Holocene occupations on fluvial shell mounds, as well as the archaeology of late pre-colonial mound-building societies.
Christopher B. Ramsey
I am a physicist, mathematician and specialist in radiocarbon dating. I am a professor of Archaeological Science at the University of Oxford. I am a member of Merton College, Oxford and a Bodley Fellow. My doctorate, completed in 1987, included the first successful implementation of carbon dioxide gas as a target for radiocarbon dating via accelerator mass spectrometry.
In the early 1990s, I became interested in the application of Bayesian statistics to the analysis of radiocarbon data. In 1994, I authored OxCal, an online radiocarbon calibration program. My research has made significant contributions to various chronological issues, including the Minoan eruption of Thera, the British Neolithic, the dispersal of modern humans out of Africa and the Egyptian chronology. I am also interested in the improvement of the radiocarbon calibration record. I am a member of the International Calibration (IntCal) group. My work has focused on improving the radiocarbon calibration record and synthesizing radiocarbon data with other chronometric information. In October 2012, with colleagues working on the Lake Suigetsu project we published the first wholly terrestrial radiocarbon calibration record extending back to the limit of the technique.

My research interests are in the fields of Palaeoecology, Palaeolimnology, Ecology, and Botany, with emphasis on Quaternary Palynology of Brazilian ecosystems. In my research, I also use diatom frustules in palaeoecological and climatic reconstructions. In the last five years, I have been the coordinator for USP in a Forensic Palynology project, in collaboration between the academic institutions and the Brazilian Federal Police of São Paulo to determine sources and routes of illegal drugs within Brazil.
Francisco William da Cruz (Chico Bill)
I graduated in Geology from the Federal University of Rio Grande do Norte, have a Master in Geosciences with emphasis on geomorphology and geology of karst terrains by the graduate program in Geochemistry and Geotectonics from the University of São Paulo (1998), a doctorate in isotopic geochemistry by the same program at the University of São Paulo (2003), and a post-doctorate by the University of Massachusetts in the USA, between 2004 and 2007. I am also working with stable isotope geochemistry and I was a FAPESP Young Researcher fellow between 2007 and 2011. Currently, I am a professor at the Institute of Geosciences at the University of São Paulo, undertaking paleoclimatic and paleoenvironmental studies based on the geochemistry of speleothems from different Brazilian regions.
I am an Associate Professor at the Department of Archaeology at the University of Reading. I am a bioarchaeologist who specialises in stable isotope analysis of bone for the reconstruction of human and animal diets. I have a background in biological anthropology and early historical archaeology and my research interests include dietary changes related to cultural and socio-economic transitions over the last 2000 years, as well as questions of diet, health and social identity in the past.
I am a geographer at the University of Bern, Switzerland, who studies landscape evolution and human-environment interactions in southern Amazonia during the Holocene. My interests include neotectonics, fluvial geomorphology, paleosols, pre-Columbian agriculture and settlement patterns and the region’s earliest hunter-gatherer occupations. In particular, during the last five years, I have been investigating the human presence, landscape modifications and environmental change during the Holocene in the Llanos de Moxos – Bolivian Amazon. My last project was “The Early People of Amazonia and the Beginning of Plant Domestication”, funded by: EU, Marie Skłodowska-Curie Action. In HERCA, I take care of Work Package 3: Landscape Reconstruction. I examine how neotectonic events and river avulsions shaped the landscape of the Llanos de Moxos during the last 10.000 years.
I am an archaeologist specialising in the integration of plant microfossil analysis (phytoliths and starch grains) to understand plant resource use, cultivation and management practices, and past landscape transformations in pre-Columbian Amazonia. I have mainly worked in Southwestern Amazonia, publishing on topics such as the environmental impact of the enigmatic ‘geoglyph’ sites, and the long-term history of plant resource use at the > 6,000-year-old Teotonio and Monte Castelo archaeological sites, both of which are case studies in the HERCA project. My current FAPESP Young Researcher grant, ‘Peoples, Plants and Landscapes in Amazonia (2018-present)’ has funded the installation of the Microbotany Laboratory at MAE-USP, one of the first of its kind in Brazil, where the phytolith and starch grain analyses related to the HERCA project will be carried out. Other collaborations linked to my Young Researcher grant include the study of Pleistocene/Holocene resource use in the Lower Amazon, the geoarchaeology of forest/savanna dynamics in the Montanha and Mangabal ribeirinho territory, in the Upper Tapajós river, and the ethnoarchaeology of plant and soil management among the Kuikuro of the Upper Xingu Indigenous Territory. My eventual goal is to combine archaeological and palaeoecological data with indigenous and traditional knowledge to advance current conservation and geopolitical debates in the Amazon.
I am a lecturer at the Department for the Anthropology of the Americas, Rheinische Friedrich-Wilhelms-Universität Bonn, Germany. My research is focused on complex societies of the southwest Amazon, expansion and ethnogenesis processes in the southern lowlands of South America, and cultural heritage. I have led ~15 field expeditions in the Bolivian Amazon working as Co-Director of the Mojos Archaeology Project in Bolivia on behalf of the German Archaeological Institute and the Unidad Nacional de Arqueología of Bolivia. These research projects include the archaeological sites of Loma Salvatierra, Bella Vista and Jasiaquiri. In HERCA, I am in charge of the archaeological excavations of the habitation mound of Loma La Punta (in the Monumental Mounds Region) and Pedras Negras (in the ring ditches of the Guaporé River). My archaeological experience of the ‘Llanos de Moxos’ region, together with my comparative perspective, will provide a regional context for our study cases, as well as improving understanding of the cultural materiality across time and space. I also participated in the following archaeological projects: “Mojos Pre-Hispanic 3D”: Mapping of monumental mounds in the Llanos de Mojos using LiDAR technology (2019); Cultural heritage tourism in the Versalles Itonama Indigenous Community (2018-2019); The Diversity of Ceramic Styles in the Iténez Region, Bolivia / Brazil border (2011-2014). I have also organized exhibitions, published a catalogue of ethnographic feather-work, and edited a book on archaeological ceramics on the whole Amazon, in collaboration with the Museo Paraense Emílio Goeldi, in Belem. I have chaired workshops and was the President of the last International Meeting of Amazonian Archaeology in Trinidad, Bolivia, 2017.
I am an archaeologist, with expertise in macro- and micro-archaeobotanical remains. I have a degree in History from the University of Sao Paulo, a master’s degree in Archaeology from MAE-USP, and am currently doing my PhD at the same institution. My research focuses on the relationships between plant cultivation, environmental management and mobility patterns among indigenous peoples of the late pre-colonial period (1,000 – 1,500 AD) in the southwestern Amazon, to assess the impact of European colonization on the floristic biodiversity used by indigenous people and in their forms of social organization and interethnic networks. I have also studied the well-known Formative period, which in the Amazon has been correlated with the beginning of agriculture, and demonstrated, through my research in the ‘sambaqui’ Monte Castelo shell mound, that there is a continuity in the strategies of food acquisition between the pre-ceramic and ceramic periods. Furthermore, I have experience with historical documentary collections in the Amazon during the colonization period, and experience with collaborative archaeological projects in Conservation Units. I am also compiling a reference collection of the plants used by the Jamamadi indigenous group, inhabitants of the Jarawara – Jamamadi – Kanamati (AM) Indigenous Land. In 2018, I received the Luiz de Castro Faria Award from the National Historical and Artistic Heritage Institute (IPHAN) in the master’s thesis category.
I graduated in History and Languages, Literature and Cultures from the University of São Paulo (USP) (2012). I have a Masters in Archaeology from the Federal University of Sergipe (UFS) (2018). During my master’s degree, I developed my research on the archaeological ceramic record from the Teotônio site (Study area 3 of HERCA project), one of the most significant archaeological sites in the region of the upper Madeira river. Since 2012, I have participated at the MAE-USP Archaeology of the Tropics Laboratory (ARQUEOTROP), where I took part in several fieldtrips and in the curation and analysis of archaeological lithic and ceramic material from the Amazon. Currently, I am a PhD student with a FAPESP fellowship in Archaeology at the Archaeology and Ethnology Museum (MAE-USP), supervised by Dr Eduardo Neves. My research interests are in archaeological ceramics from the Amazon; long-term indigenous history; contributions between Archaeology, Linguistics, History and Literature; Landscape; Historical Ecology and Meaningful and Persistent Places. As a member of the HERCA project, I will focus mainly on the upper Madeira River region, doing fieldwork and analysing archaeological material from the excavations.
I am based in the University of Reading, working as a Teaching Fellow in the Museum of English Rural Life. I am interested in the social and economic impact of cultural heritage and museums and community engagement. My PhD thesis analysed the development of Lumbini, Birthplace of the Buddha and UNESCO World Heritage Site and its impact on surrounding local communities. Alongside my doctoral research, I have also been involved in several projects led by Durham University’s UNESCO Chair, primarily at South Asian and World Heritage sites. I joined the HERCA project in January to support the impact activities. The main aim is to engage with museums to strengthen the cultural identity of inhabitants of the Beni province of Amazonian Bolivia and foster awareness of its sustainable land-use potential. The project will co-design and develop approaches with partner institutions and local stakeholders to better mobilise the educational potential of local museums, through exhibitions and other learning resources, and disseminate the results of the research to a wider local and international audience.
Myrtle P. Shock
I received a B.Phil in Anthropology from the University of Pittsburgh (2003) and an M.A. (2005) and PhD (2010) in Anthropology from the University of California, Santa Barbara. Currently, I am an assistant professor in the Anthropology and Archaeology Department at the Federal University of Western Pará State (UFOPA), in Santarém, Brazil. My research examines human food choice and environmental modifications across the Holocene. I started these investigations in Central Brazil and currently, my research focuses on the Amazon with participation in multiple collaborative projects across the basin. Recently, I collaborated on the project “Exploration, Mapping and Excavation on the Fluvial Shellmounds of the Guaporé Basin, Southwestern Amazonia” of the National Geographic Society (2014-2016). My involvement in the HERCA project is with the analysis of macro-botanical remains of Early to Middle Holocene contexts and the supervision of students. The main research question is how human populations modified their environment and the availability of plant resources. In this project I will be training Brazilian and Bolivian in archaeobotany. In 2020 I participated in the fieldwork at the Monte Castelo shell mound (Brazilian-Bolivian border) and will later go to the Teotónio site (Southwestern Brazil). I also teach students at the Universidade Maior de San Andrés, who are analyzing remains from the archaeological sites in the Bolivian Llanos de Mojos.
I have a BSc in History from the University of São Paulo (2011), an MSc in Quaternary and Prehistory from the Natural History Museum of Paris (2013), and a PhD in Archaeology (2018) as a dual-degree from the Natural History Museum of Paris and the University of São Paulo. Currently, I’m an assistant professor in the Anthropology and Archaeology Department at the Federal University of Western Pará State (UFOPA), in Santarém, Brazil. Since 2010 I have been interested in past human-animal relations in Amazonian societies, focusing on the study of faunal remains from archaeological sites. I started these investigations in the central Amazon studying food choices. More recently, I started to work in Southwestern Amazonia, studying fish environments and human landscape modifications, such as ponds and weirs, related to seasonal water cycles. Recently, I have started to collaborate on the project “Exploration, Mapping and Excavation on the Fluviatil Shellmounds of the Guaporé Basin, Southwestern Amazonia” (National Geographic Society, 2014-2016), and on the AHRC-FAPESP HERCA project. In HERCA, I will investigate the correlations between the archaeological fauna and recorded paleoenvironmental conditions to better understand the local manifestations of environmental fluctuations through the Holocene. I have been to the Monte Castelo shell mound (Brazilian-Bolivian border) in 2020 and I will visit the archaeological sites of the Llanos de Mojos (Bolivia). I am also actively training students in Zooarchaeology and in this capacity will travel to the Universidade Maior de San Andrés in Bolivia.
I am an archaeologist with a PhD from the Department of Anthropology at Harvard University. I have worked in Peru, Brasil, and Jordan, and my doctoral dissertation employed zooarchaeology, microbotany, and stable isotope analysis to examine the role of llama caravans in the Central Andes of Peru at 3,000 B.C. As a member of the HERCA team, my primary aim is to reconstruct paleoclimate by employing δ18O analysis of freshwater snails at Monte Castelo. More broadly, I am interested in foodways and human-environment interactions across South America.
Fernando Ozorio de Almeida
I am a specialist in the study of long-term indigenous histories in South-American Lowlands. I graduated in History at the University of São Paulo and I also received an MSc and a PhD degree from the Museum of Archaeology and Ethnology of the same university. My studies have focused on southern Amazon. During 2018-2019 I hold a post-doctoral research position at the Museo de La Plata (Argentina). For sixteen years I have studied the history (pre-colonial and colonial) of the Tupian groups who were the most pervasive group of the lowlands by the time of the European arrival, roughly delimiting the territory which is today Brazil. Since 2014, I have been an assistant professor in Universidade Federal de Sergipe, supervising undergraduate and graduate (MA and PhD) students related to projects in Amazonia, in the Brazilian Northeast and elsewhere. Since 2008 I have focused my research in the Upper Madeira region. Within the HERCA Project, my participation is related to the survey and excavation of archaeological sites on the Mamoré and Madeira Rivers, including the archaeological excavations on the Teotônio site. Moreover, I will contribute with the interpretation and synthesis of the ceramic analysis coming from these sites.
Lautaro Maximilian Hilbert
Currently, I am working in south Brazil as a field archaeologist and phytolith analyst. As a previous member of the Pre-Columbian Amazon Scale Transformations (PAST) project at the University of Exeter, I participated in excavations on Amazonian Dark Earth sites in the Lower Tapajós and around Laguna Versalles in the Iténez Forest Reserve, Bolivia. I have extensive experience recording and presenting archaeological and archaeobotanical data using the stratigraphic plotting software C2 Version 1.7.7. and, I also have experience working on the statistical multi-paradigm numerical computing environment program, MatLab version R2017a. My areas of interests are in pre-Colombian archaeobotanical studies from lowland Amazonian region, centred in plant domestication and plant management.
Guilherme Mongelo Zdonek
I am an archaeologist with a BSc in History from the University of São Paulo. I also obtained my Master’s and PhD. degrees in Archeology at the Museum of Archeology and Ethnology of the same university. I have experience working with Amazonian archaeology since 2008, and for the last nine years, I have contributed with the archaeological project in the region of the upper Madeira River. My master’s research dealt with the old layers of Terra Preta at the Teotônio site (Study area 3). I delved into this subject in my doctoral research, where I analyzed the material culture of the earliest human occupations in this site. Currently, I work as a professor and researcher at Escuela Superior Politécnica del Litoral – ESPOL, in Ecuador. As a member of the HERCA project, I will contribute with the various analyzes of the archaeological contexts of the initial human occupations in the upper Madeira River sites, focusing on the lithic materials.
I have a Bachelor’s Degree in Oceanography from the Federal University of Pará (2013), with a Professional Master’s Degree in Sustainable Use of Natural Resources in Tropical Regions by Vale Institute of Technology (2015) and a PhD in Science (2020) from the Center for Nuclear Energy in Agriculture (CENA / USP), with internship (2008) at the University of Sorbonne, France. My areas of expertise are palaeobotany and palaeoclimatology, with a focus on paleoenvironmental reconstruction studies and paleoclimatic inferences in the Amazon, in which I apply tools such as palynology, charred particles, stable isotopes (C, N) and Carbon-14, as well as stable isotopes of H and C in specific compounds (n-alkanes, fatty acids) preserved in lake sediments to obtain information about paleo precipitation throughout the Late Quaternary.
I am a Palaeoecologist, with a BSc in Geography from King’s College London (2018) and an MSc in Quaternary Science from Royal Holloway, University of London (2019). I am currently undertaking a PhD in Environmental Science at the University of Reading (2020- ), supervised by Prof. Frank Mayle. My project aims to determine the impact Pre-Columbian societies had on their surrounding rainforest/savannah ecosystems, particularly focusing upon the Monumental Mound Region of the Llanos de Mojos (Study Area 1). This involves using fossil pollen and charcoal as palaeoecological proxy records to reconstruct past changes in vegetation composition and fire activity. In addition, I will be developing an Agent-based Model (using the NetLogo modelling software) to provide an insight into how this Pre-Columbian society may have domesticated the surrounding rainforest, as well as the legacy of their activities.
I am an archaeological scientist and radiocarbon dating expert, with MSc and DPhil (PhD) degrees from the Research Laboratory for Archaeology and the History of Art (RLAHA), University of Oxford. My research involves the construction of reliable, high-resolution chronologies using radiocarbon dating and Bayesian age modelling techniques, and focuses on the interface between past human occupations, ecology, and climate. Past projects include the establishment of timelines for hominin (modern humans and Neanderthals) dynamics during the Middle to Upper Palaeolithic Transition in the Zagros Mountains, and the initial arrival of humans to the Americas around the Last Glacial Maximum. As a member of the HERCA team, my primary aim is to produce/manage radiocarbon data for the creation of highly resolved human occupation and palaeo-environmental sequences. The integration of these results will help us better understand the relationship between humans, ecological and climatic changes in pre-Columbian Amazonia.
I am a Physical Geographer, PhD. in Geosciences and Environment (2014 – São Paulo State University), and postdoc at the University of São Paulo and Imperial College London (2015-2017). Since 2017, I am an Associate Professor in Geomorphology and Environment of the Department of Environmental Sciences, Federal University of São Paulo (Unifesp), Brazil. My main research interest is understanding “how large rivers respond to environmental changes across spatiotemporal scales”, using remote sensing, morphosedimentary analysis, and geochronological tools, such as luminescence dating and cosmogenic nuclides analysis. Most of his research has been performed in the largest South American fluvial systems, including Amazon, Orinoco, Pantanal, Paraná, and São Francisco.
