Two centuries of hydroclimatic variability reconstructed from tree-ring records over the Amazonian Andes of Peru
(Blackwell Publishing, 2020-09)
Almost half of the tributaries of the Amazon River originate in the tropical Andes and support large populations in mountain regions and downstream areas. However, it is difficult to assess hydroclimatic conditions or to ...
Multi-century lake area changes in the Southern Altiplano: A tree-ring-based reconstruction
(Copernicus Publications, 2015-09-15)
Size fluctuations in endorheic lakes in northwestern Argentina (NWA) and southwestern Bolivia (SWB) are very sensitive to basin hydrological balances, and consequently, very vulnerable to deleterious effects from climatic ...
A comparison of some simple methods used to detect unstable temperature responses in tree-ring chronologies
(Elsevier Gmbh, Urban & Fischer Verlag, 2018-04)
Temporal stability of the relationship between a potential proxy climate record and the climate record itself is the foundation of palaeoproxy reconstructions of past climate variability. Dendroclimatologists have spent ...
Reconstruction of precipitation and temperature with annual growth rings of the cypress Taxodium mucronatum (Taxodiaceae) in Coahuila, MexicoReconstrucción de precipitación y temperatura con anillos de crecimiento anual del ciprés Taxodium mucronatum (Taxodiaceae) en Coahuila, México

El Niño modulations during the past seven centuries
(Nature Publishing Group, 2013-07-02)
Predicting how the El Niño/Southern Oscillation (ENSO) will change with global warming is of enormous importance to society. ENSO exhibits considerable natural variability at interdecadal?centennial timescales. Instrumental ...
Two centuries of hydroclimatic variability reconstructed from tree-ring records over the Amazonian Andes of Peru
(Universidad Continental, 2020)
Almost half of the tributaries of the Amazon River originate in the tropical Andes and support large populations in mountain regions and downstream areas. However, it is difficult to assess hydroclimatic conditions or to ...
Ranking of tree-ring based hydroclimate reconstructions of the past millennium
(Pergamon-Elsevier Science Ltd, 2020-02)
To place recent hydroclimate changes, including drought occurrences, in a long-term historical context, tree-ring records serve as an important natural archive. Here, we evaluate 46 millennium-long tree-ring based hydroclimate ...
Snowpack variations since AD 1150 in the Andes of Chile and Argentina (30°-37°S) inferred from rainfall, tree-ring and documentary records
(American Geophysical Union, 2012-06)
The Andean snowpack is the main source of freshwater and arguably the single most important natural resource for the populated, semi-arid regions of central Chile and central-western Argentina. However, apart from recent ...
