TL;DR: Present-day C3-dominated paramo vegetation is therefore not an analogue for past C4-dominated vegetation (with abundant Sporobolus lasiophyllus), and during the last glacial cycle the ecological tolerance of Quercus may have increased.

TL;DR: In this article, plant microfossil and macrofossils associations obtained from six dated sections from the area of the basin of Bogota (2550 m, Eastern Cordillera, Colombia) show the evolution of the late Neogene Andean montane forest, triggered by the Andean orogeny.

TL;DR: In this article, the authors present a reconstruction of forest history and climatic change based on 11 pollen records from eight sites, all located in the lower montane forest belt of the northern Andes in Colombia.

TL;DR: A pollen record from Timbio, located at an elevation of 1750m on the high plain of Popayán, forms the basis for reconstructing the vegetation and climate history for the periods from 27000 to 9200 radiocarbon years before the present (14Cyr BP) and 2100 to sub-recent.

TL;DR: An environmental reconstruction of the last 10,000 14C years of a frequently flooded wetland ecosystem in the lower Magdalena valley in northern Colombia is presented, on the basis of a multi-disciplinary study of the sediments of the upper 15 m of the core from Boquillas (74°33'E, 9°7'N; 20 m a. s. l.). as discussed by the authors.
