Paleoenvironmental history of the Popayán area since 27 000 yr BP at Timbio, Southern Colombia.
TLDR
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.About:

Quaternary Ice-Age dynamics in the Colombian Andes: developing an understanding of our legacy
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 paper, the biomisation method is used to reconstruct Latin American vegetation at 6000±500 and 18 000±1000 radiocarbon years before present (14C yr BP) from pollen data.

TL;DR: In this paper, the authors identify 60 vegetation (pollen) records from across South America which satisfy geochronological requirements set out for climate modelling, and discuss their sensitivity to the spatial signature of climate modes throughout the continent.

Holocene environmental change at the upper forest line in northern Ecuador
TL;DR: In this article, the authors reconstructed the position of the upper forest line (UFL) during the last 6000 years using a 90 cm long sediment core G15-II from a small mire at 3400 m elevation, 200 m below the actual UFL in Guandera Biological Reserve.

TL;DR: The assignment of Colombian pollen data to biomes allows the data to be synthesised at 10 ‘time windows’ from the present-day to 6000 radiocarbon years before present (BP) as discussed by the authors.

TL;DR: In this article, the potential of a bioecological classification of tropical forests to organize quantitative data on undercanopy environments into a predictive system was examined, and a brief explanatory Life Zone mapping exercise was conducted in Thailand during 1965.

TL;DR: A 30,000-year paleotemperature record derived from noble gases dissolved in carbon-14-dated ground water indicates that the climate in lowland Brazil (Piaui Province, 7 degrees S, 41.5 degrees W; altitude, 400 meters) was 5.4 degrees +/- 0.6 degrees C cooler during the last glacial maximum than today.

TL;DR: In this paper, the reliability of the data was evaluated using explicit criteria and some types of data were re-analysed using consistent methods in order to derive a set of mutually consistent palaeoclimate estimates of mean temperature of the coldest month (MTCO), mean annual temperature (MAT), plant available moisture (PAM), and runoff (P-E).
