This study presents the first multi‐proxy palaeoenvironmental and palaeoclimatic history for northern South America based on the palaeolimnological reconstruction of a pond located in a dry paramo at 3570 masl. During the Last Glacial Maximum (LGM), the study area was under glacial conditions, then during global events Heinrich Stadial 1 (HS1), Bølling–Allerød (BA), and the Younger Dryas (YD), the pond expanded, accumulation rates and proxies for erosion reached the highest values, indicative… 
Late Quaternary Abrupt Climate Change in the Tropics and Sub‐Tropics: The Continental Signal of Tropical Hydroclimatic Events (THEs)
Tropical hydroclimatic events, characterized by extreme regional rainfall anomalies, were a recurrent feature of marine isotope stages 2–4 and involved some of the most abrupt and dramatic climatic


Pollen‐ and diatom based environmental history since the Last Glacial Maximum from the Andean core Fúquene‐7, Colombia
The late Pleistocene–Holocene ecological and limnological history of Lake Fúquene (2580 m a.s.l.), in the Colombian Andes, is reconstructed on the basis of diatom, pollen and sediment analyses of the

Major altitudinal shifts in Andean vegetation on the Amazonian flank show temporary loss of biota in the Holocene
The Lateglacial and Holocene vegetation history from the Amazonian flank of the south Colombian Andes has been studied in a 12 m long sediment core from Lake La Cocha (2780 m altitude). 18 AMS 14C
Integrated diatom-pollen based Holocene environmental reconstruction of lake Las Margaritas, eastern savannas of Colombia
A multiproxy analysis that includes diatoms, pollen, element geochemistry, carbon content analysis, and radiocarbon dates was carried out on a core from Las Margaritas (3023‘N, 73026’W) in order to
