      Fuentealba, Magdalena; Latorre, Claudio; Frugone Álvarez, Matías; Sarricolea Espinoza, Pablo; Giralt, Santiago; Contreras López, Manuel; Prego, Ricardo; Bernárdez, Patricia; Valero Garcés, Blas (Nature, 2020)
      Human activities have profoundly altered the global nutrient cycle through Land Use and Cover Changes (LUCCs) since the industrial revolution and especially during the Great Acceleration (1950 CE). Yet, the impact of such ...
    • Chronology, stratigraphy and hydrological modelling of extensive wetlands and paleolakes in the hyperarid ... 
      Pfeiffer, Marco; Latorre, Claudio; Santoro, Calogero M.; Gayo, Eugenia M.; Rojas, Rodrigo; Carrevedo, María Laura; McRostie, Virginia B.; Finstad, Kari M.; Heimsath, Arjun; Jungers, Matthew C.; De Pol-Holz, Ricardo; Amundson, Ronald (Elsevier Ltd, 2018)
      © 2018 Elsevier LtdThe halite-encrusted salt pans (salars) present at low elevations in the hyperarid core of the Atacama Desert in northern Chile are unique features of one of the driest and possibly oldest deserts on ...
    • Continuities and discontinuities in the socio-environmental systems of the Atacama Desert during the last ... 
      Santoro, Calogero M.; Capriles, José M.; Gayo, Eugenia M.; Porras, María Eugenia de; Maldonado, Antonio; Standen, Vivien G.; Latorre, Claudio; Castro, Victoria; Angelo, Dante; McRostie, Virginia; Uribe Rodríguez, Mauricio; Valenzuela, Daniela; Ugalde, Paula C.; Marquet, Pablo A. (Elsevier, 2017)
      Understanding how human societies interacted with environmental changes is a major goal of archaeology and other socio-natural sciences. In this paper, we assess the human-environment interactions in the Pampa del Tamarugal ...
    • Dietary diverstiy in the Atacama desert during the Late intermediate period of northern Chile 
      Alfonso-Durruty, Marta P.; Gayo, Eugenia M.; Standen, Vivien; Castro, Victoria; Latorre, Claudio; Santoro, Calogero M.; Valenzuela, Daniela (Elsevier Ltd, 2019)
      The Pacific Ocean that flanks the hyperarid Atacama Desert of Northern Chile is one of the richest biomass producers around the world. Thus, it is considered a key factor for the subsistence of prehistoric societies ...
    • Hunter-gatherer mobility strategies in the high andes of northern Chile during the latepleistocene-early ... 
      Osorio, Daniela; Capriles, ,Jose M.; Ugalde, Paula C.; Herrera, Katherine A.; Sepulveda, Marcela; Gayo, Eugenia M.; Latorre, Claudio; Jackson Squella, Donald; De Pol Holz, Ricardo; Santoro, Calogero M. (Taylor & Francis, 2017)
      The high Andes of western South America feature extreme ecological conditions that impose important physiological constraints on humans including high-elevation hypoxia and cold stress. This leads to questions regarding ...
    • Late Quaternary vegetation and climate history of a perennial river canyon in the Río Salado basin (22°S) ... 
      Latorre, Claudio; Betancourt, Julio L.; Arroyo, Mary T. K. (2006)
      Plant macrofossils from 33 rodent middens sampled at three sites between 2910 and 3150 m elevation in the main canyon of the Río Salado, northern Chile, yield a unique record of vegetation and climate over the past 22,000 ...
    • Loco or no Loco? holocene climatic fluctuations, human demography, and community basedmanagement of coastal ... 
      Santoro, Calogero M.; Gayo, Eugenia M.; Carter, Chris; Standen, Vivien G.; Castro Rojas, María Victoria; Uribe Valenzuela, Daniela Paz; De Pol-Holz, Ricardo; Marquet, Pablo A.; Latorre, Claudio (Frontiers Media SA, 2017)
      The abundance of the southern Pacific mollusk loco (Concholepas concholepas), among other conspicuous marine supplies, are often cited as critical resources behind the long-term cultural and demographic fluctuations of ...
    • Pollen analyses from a 50 000-yr rodent midden series in the southern Atacama Desert (25° 30′ S) 
      Maldonado, Antonio; Betancourt, Julio L.; Latorre, Claudio; Villagran, Carolina (John Wiley and Sons Ltd, 2005)
      Precipitation in northern Chile is controlled by two great wind belts - the southern westerlies over the southern Atacama and points south (> 24° S) and the tropical easterlies over the northern and central Atacama ...
    • Rare calcium chloride-rich soil and implications for the existence of liquid water in a hyperarid environment 
      Pfeiffer, Marco; Latorre, Claudio; Gayo, Eugenia; Amundson, Ronald (Geological Society of America, 2019)
      We discovered permanently hydrated CaCl 2 -rich soils in Earth's driest region, the Atacama Desert. The soils contain up to ~15% CaCl 2 . X-ray diffraction indicates the rare minerals sinjarite, schoenite, and tachyhydrite. ...
