Major environmental changes were occurring when the first modern humans arrived in South America during the Pleistocene-Holocene transition. How these changes shaped human-environmental interactions across this period remain unclear. We analyzed the stratigraphy, biogeochemistry, and paleoclimatic models from the Ancient Tagua Tagua Lake (ATTL) in...
Biogeochemistry is a multidisciplinary field that offers profound insights into ancient human-environment interactions, human origins, dietary practices and environmental adaptations. By integrating various methods, biogeochemistry enables a comprehensive understanding of ecological dynamics and human history in South America.
Archaeological dates compilation for Central Chile (Valparaíso - Maule Region)
[This corrects the article DOI: 10.1371/journal.pone.0302465.].
We present the results of the excavations and analyses of the diverse and exceptional archaeological assemblage of Taguatagua 3, a new late Pleistocene site located in the ancient Tagua Tagua lake in Central Chile (34°S). The anthropogenic context is constrained in a coherently dated stratigraphic deposit which adds new information about the mobili...
Understanding socio-ecological systems over the long term can shed light on past adaptive strategies in environmentally sensitive regions. Central Chile is an emblematic case study for mediterranean ecosystems, where a progressive and sustained population increase began approximately 2000 years ago alongside significant landscape changes. In this w...
During the Formative period by the Late-Holocene (ca. 3000–1500 BP), semi-sedentary and sedentary human occupations had emerged in the oases, salares, and riverine systems in the central depression (2400–1000 masl) of the Atacama Desert, northern Chile (19–25°S). This hyperarid core was marginally occupied during the post-Pleistocene and middle Hol...
Global afforestation/deforestation processes (e.g., Amazon deforestation and Europe afforestation) create new anthropogenic controls on carbon cycling and nutrient supply that have not been fully assessed. Here, we use a watershed-lake dynamics approach to investigate how human-induced land cover changes have altered nutrient transference during th...
Carpological evidence of El Vergel Complex contexts in Isla Mocha has made it possible to infer the various uses that these groups made of their vegetable resources. Among these, the hypothesis that Zea mays was used for the elaboration of fermented drinks-which would have been part of the prestige and leadership practices related to the increase i...
