Abundance, distribution and stable carbon isotope composition of leaf-waxes (n-alkanes & fatty acids) from surface lake sediments along a climatological gradient on the western side of the Southern An
(2018)
The climate in central to southern South America on the western side of the Andes is projected to become significantly warmer and drier over the next several
decades to centuries in response to climate change. In addition, ...
Geomorfologia e geologia do quaternário da planície flúvio-eólica do Médio rio São francisco, NE do brasil
(Universidade Estadual Paulista (Unesp), 2020-05-06)
Compreender a evolução paleoclimática do Quaternário na região Nordeste do Brasil (NEB) é parte fundamental para entender como tem funcionado a circulação atmosférica na faixa tropical da América do Sul. Nesse contexto, o ...
Mid-Holocene PMIP3/CMIP5 model results: Intercomparison for the South American Monsoon System
(2013-12)
The mean precipitation fields for eastern South America from eight mid-Holocene (6 ka) simulations, part of the third phase of Palaeoclimate Modeling Intercomparison Project (PMIP3) and the fifth phase of the Coupled Model ...
Detecting hydrologic distinctions among Andean lakes using clumped and triple oxygen isotopes
(Elsevier, 2023)
Oxygen isotope distributions from lacustrine carbonates provide insights into climate and hydrological change, but it is difficult to isolate the influences of catchment precipitation δ18O, water temperature, and evaporation ...
Climatic controls of Holocene fire patterns in southern South America
(2007)
Holocene fire-climate-vegetation linkages are mostly understood at individual sites by comparing charcoal and pollen records with other paleoenvironmental proxy and model simulations. This scale of reconstruction often ...
Atmospheric circulation changes and neoglacial conditions in the Southern Hemisphere mid-latitudes: Insights from PMIP2 simulations at 6 kyr
(2011)
Glacial geologic studies in the Southern Hemisphere (SH) mid-latitudes (40-54°S) indicate renewed glacial activity in southern South America (Patagonia) and New Zealand's (NZ) South Island starting at ~7 kyr, the so-called ...
Water stable isotopes reveal the hydrological response of Costa Rican glacial lakes to climate variability
(2022)
Lakes are generally considered a key information source for understanding paleoclimate. Here, we use stable water isotopes (δ2H and δ18O) in a high-elevation tropical glacial lake to inform about modern climate variability ...
Effect of changing vegetation and precipitation on denudation - Part 1: Predicted vegetation composition and cover over the last 21 thousand years along the Coastal Cordillera of Chile
(Copernicus GmbH, 2018)
Vegetation is crucial for modulating rates of denudation and landscape evolution, as it stabilizes
and protects hillslopes and intercepts rainfall. Climate conditions and the atmospheric CO2 concentration, hereafter [CO2], ...
South Pacific Subtropical High from the late Holocene to the end of the 21st century: insights from climate proxies and general circulation models
(Copernicus Gesellschaft MHB, 2020)
The South Pacific Subtropical High (SPSH) is a predominant feature of the South American climate. The variability of this high-pressure center induces changes in the intensity of coastal alongshore winds and precipitation, ...
Evolution of Climatic Related Leaf Traits in the Family Nothofagaceae
(2018)
The current relationship between leaf traits and environmental variables has been widely used as a proxy for climate estimates. However, it has been observed that the phylogenetic relationships between taxa also influence ...
