Soil inorganic carbon (SIC) is an important component of total terrestrial stocks. However, compared to soil organic carbon, our understanding its spatial distribution and drivers relatively poor. In the literature, ratio precipitation evapotranspiration usually cited as main driver SIC worldwide, but confounding factors make it difficult assess this relationship. Chile has a unique geography with large climatic gradient along homogeneous geological setting, which why considered natural...
To present the Quaternary eolian stratigraphic record along Pacific coast of subtropical semiarid Chile (35-28ºS) has been mostly studied regarding their paleoclimate significance, nonetheless other main environmental factors are known to affect dune evolution at millennial multimillennial time scale, including sediment (i.e., mineral sand) supply linked glacial and fluvial erosion transport, eustatic sea level, coastal drift, ocean storminess, wind intensity, others. In Chile,...
Abstract. A critical aspect of predicting soil organic carbon (SOC) concentrations is the lack available information; where information on characteristics available, it usually focused regions high agricultural interest. To date, in Chile, a large proportion SOC data have been collected areas intensive or forestry use; however, vast beyond these forms land use few no available. Here we present new database for country, which result an unprecedented national effort under framework Global Soil...
Abstract We estimated the amount of carbon (C) stored in terrestrial ecosystems Chilean Patagonia and proportion within protected areas. used existing public databases that provide information on C stocks biomass soils. Data were analysed by ecosystem forest type case native forests. Our results show some have been more extensively studied both for their soils (e.g. forests) compared with others shrublands). Forests peatlands store largest because large per hectare area they cover. The total...
Abstract Background High mountainous environments are of particular interest as they play an essential role for life and human societies, while being which highly vulnerable to climate change land use intensification. Despite this, our knowledge high mountain soils in South America their microbial community structure is strikingly scarce, more concern considering the large population that depends on ecosystem services provided by these areas. Conversely, Central Andes, located Mediterranean...
In the past decade, pedological research in hyperarid environments worldwide has revealed landscapes and soil features that are regionally prevalent distinctive, but not well captured current taxonomy. Hyperarid soils bear genetic can differ considerably from those more humid desert environments. particular, they often contain horizons cemented with halite (NaCl) or heavily enriched nitratine (NaNO 3 ). Unlike commonly found regions, may also lack most vascular plants, pedogenic carbonates,...
Public architecture emerged in conjunction with the development of early complex societies and is therefore a key feature for understanding them. Anthropogenic mounds platforms southern Chile dated to Late Ceramic Period (AD 1000–1550), historic indigenous inhabitants 1550–present) are southernmost manifestation public Americas. We report results from excavation an architectural on Mocha Island that covers area ~9.2 ha volume ~43,000 m 3 . This paper describes its construction dynamics,...

Abstract This paper reports a previously unidentified paleoenvironmental record found in sand dunes of the Atacama Desert, Chile. Long-term aeolian deflation by prevailing onshore winds has resulted deposition on irregular surface Miocene-aged anhydrite outcrop. Two deposits ~25 km apart, along wind trajectory, were hand excavated then analyzed for vertical (and temporal) changes physical and chemical composition. Radiocarbon ages organic matter embedded within show that rapid accumulation...

Abstract. Spatial soil databases can help model complex phenomena in which soils are decisive, for example, evaluating agricultural potential or estimating carbon storage capacity. The Soil Information System Latin America and the Caribbean, SISLAC, is a regional initiative promoted by FAO's South American Partnership to contribute sustainable management of soil. SISLAC includes data coming from 49,084 profiles distributed unevenly across continent, making it region's largest database....
We present a Sr isotopic database (⁸⁷Sr/⁸⁶Sr) of the main lithologies southern Central Andes (33°–34°S), using compilation available information igneous rocks and new chemical analysis sedimentary rocks. These samples correspond to shales, limestones fine-grained sandstones from various Mesozoic formations in Main Coastal Cordillera. The previous studies reveals existence two groups. first set includes Quaternary with ⁸⁷Sr/⁸⁶Sr ratios between 0.7044 0.7059, associated magmatic contamination...
