Constraining the population size estimates of the pre-Columbian Casarabe Culture of Amazonian Bolivia Open
The capacity of Amazonian environments to support large indigenous societies prior to European Contact has long been a contentious area of debate, particularly in regions where pre-Columbian cultures are known to have constructed large, sp…

Localised land-use and maize agriculture by the pre-Columbian Casarabe Culture in Lowland Bolivia Open
Multiple pre-Columbian (pre-1492 CE) archaeological sites now challenge the traditional portrayal of Amazonia as a ‘pristine wilderness’. This is especially true within the forest-savanna mosaic landscapes of lowland Bolivia, where the pre…

Ecological responses of the Atlantic Forest biodiversity hotspot to Holocene climate change: Insights from the Lagoa Canto Grande pollen record, Espirito Santo, coastal Brazil Open
This study presents the modern pollen signature and Holocene vegetation and climate history of the evergreen forest and associated ecosystems in the Bahia Coastal Forest ecoregion of Brazil's Atlantic Forest biodiversity hotspot. Artificia…

A conservation assessment of Brazil's iconic and threatened Araucaria Forest-Campos mosaic Open
Southern Brazil's highland Araucaria Forest-Campos grassland mosaic is an ancient and iconic landscape in the globally important Atlantic Forest biodiversity hotspot. Human land use has inflicted significant losses on the region's natural …

Fire-human-climate interactions in the Bolivian Amazon rainforest ecotone from the Last Glacial Maximum to late Holocene Open
The Amazon Rainforest Ecotone (the ARF- Ecotone ) of the southwestern Amazon Basin is a transitional landscape from tropical evergreen rainforests and seasonally flooded savannahs to savannah woodlands and semi-deciduous dry forests. While…

Spatial and temporal abilities of proxies used to detect pre-Columbian Indigenous human activity in Amazonian ecosystems Open
Humans have been modifying ecosystems since before the Holocene began ca. 12,000 years ago, even in Neotropical regions. The Amazon was once thought to be ‘pristine’ and only lightly impacted by Indigenous people before European colonisati…

An Assessment of Soil Phytolith Analysis as a Palaeoecological Tool for Identifying Pre-Columbian Land Use in Amazonian Rainforests Open
Phytolith analysis is a well-established archaeobotanical tool, having provided important insights into pre-Columbian crop cultivation and domestication across Amazonia through the Holocene. Yet, its use as a palaeoecological tool is in it…

Response of Amazonian forests to mid‐Holocene drought: A model‐data comparison Open
There is a major concern for the fate of Amazonia over the coming century in the face of anthropogenic climate change. A key area of uncertainty is the scale of rainforest dieback to be expected under a future, drier climate. In this study…

Widespread reforestation before European influence on Amazonia Open
Pre-Columbian reforestation in Amazonia An early 17th-century temporary reduction in global atmospheric carbon dioxide (CO 2 ) levels was previously attributed to reforestation in Amazonia after the catastrophic loss of life of the indigen…

Insights into past land-use and vegetation change in the Llanos de Moxos (Bolivia) using fungal non-pollen palynomorphs Open
Here we document a 1000-year fungal record from the raised-field region of the Llanos de Moxos, a seasonally inundated forest-savanna mosaic in the Bolivian Amazon. Fungi are extremely sensitive to changes in vegetation due to their close …

Archaeology and ethnography demonstrate a human origin for Amazonian Dark Earths Open
Archaeological research provides clear evidence that the widespread formation of Amazonian Dark Earths (ADEs) in tropical lowland South America was concentrated in the Late Holocene, an outcome of sharp demographic growth that peaked towar…

Evidence confirms an anthropic origin of Amazonian Dark Earths Open
First described over 120 years ago in Brazil, Amazonian Dark Earths (ADEs) are expanses of dark soil that are exceptionally fertile and contain large quantities of archaeological artefacts. The elevated fertility of the dark and often deep…

Long-term impacts of mid-Holocene drier climatic conditions on Bolivian tropical dry forests Open
The Bolivian Chiquitano dry forest is the largest block of intact seasonally dry tropical forest in South America and is a priority ecoregion for conservation due to its high threat status. However, the long-term impacts of drier climatic …

Cold spot microrefugia hold the key to survival for Brazil's Critically Endangered Araucaria tree Open
Brazil's Araucaria tree ( Araucaria angustifolia ) is an iconic living fossil and a defining element of the Atlantic Forest global biodiversity hotspot. But despite more than two millennia as a cultural icon in southern Brazil, Araucaria i…

Constraining pollen-based estimates of forest cover in the Amazon: A simulation approach Open
Pollen dispersal and deposition (PDD) modelling has been instrumental in reconstructing historical vegetation in temperate regions, but its application has been limited in the tropics where there is greatest uncertainty in past land cover …

The ACER pollen and charcoal database: a global resource to document vegetation and fire response to abrupt climate changes during the last glacial period Open
Quaternary records provide an opportunity to examine the nature of the vegetation and fire responses to rapid past climate changes comparable in velocity and magnitude to those expected in the 21st-century. The best documented examples of …
