Exploring the Causes of Multicentury Hydroclimate Anomalies in the South American Altiplano with an Idealized Climate Modeling Experiment Open
Paleoclimate records have long documented the existence of multicentury hydroclimate anomalies in the Altiplano of South America. However, the causes and mechanisms of these extended events are still unknown. Here, we present a climate mod…

Microbial communities inhabiting 600-year-old sediments in the Inka-Coya Lake located in the Atacama Desert Open
Lacustrine sediments are natural archives for the surrounding area's biogeochemical dynamics; in particular, the isolation and extreme conditions in which desert lakes are located make them ideal study models for studying perturbations in …

A 15 000 cal a paleoclimatic record from Laguna del Viento (33°S), Subtropical Andes, central Chile Open
Subtropical zones are crucial for understanding climate dynamics, as they strongly control the subtropical anticyclone system and serve as a bridge between the tropical and temperate regions of the planet. Therefore, understanding the long…

Holocene environmental and climate evolution of central west Patagonia as reconstructed from lacustrine sediments of Meseta Chile Chico (46.5° S, Chile) Open
Holocene environmental changes in Patagonia were mostly shaped by fluctuating ice cover recession. Consequently, environmental reconstructions are largely based on discontinuous moraine chronologies from valley deposits. Here, we present a…

Regional phytoliths from the Coastal Cordillera of the Atacama Desert, Chile, and their potential for paleoecological reconstructions Open
Siliceous phytoliths are frequently used in archaeology and Quaternary paleoecology. In order to validate the potential of phytoliths to reconstruct the vegetation history in the Atacama Desert, Chile, we analyzed the occurrence and morpho…

A multiproxy approach to reconstruct the Late Holocene environmental dynamics of the semiarid Andes of central Chile (29°S) Open
Mountain ecosystems located in the Andes cordillera of central Chile (29–35°S) have been strongly affected by the ongoing Mega Drought since 2010, impacting the snow cover, the surficial water resources (and thereby water storage), as well…

Precipitation variability, vegetation turnover, and anthropogenic disturbance over the last millennium in the Atacama highlands of northern Chile (19°S) Open
The Late-Holocene history of hydroclimatic variability in the Atacama Desert offers insights into the effects of precipitation and humans on ecosystems in one of the most extremely arid regions of the world. However, understanding the effe…

Holocene Environmental Dynamics of the Lago Cochrane/Pueyrredón Valley, Central West Patagonia (47°S) Open
Deglaciation modeling of the Patagonian Ice Field since the Last Glacial Maximum has been a topic of intensive research in Central West Patagonia (44°–49°S). However, the chronology of deglaciation onset, acceleration, and the subsequent t…
