Multi-proxy paleoecological analysis of a high-altitude site in central Mexico
High-mountain lakes constitute key archives of past environmental dynamics and climate change. This study aims to reconstruct Holocene vegetation dynamics, fire regimes and hydroclimatic history of a high-altitude pond in central Mexico using a multiproxy approach. The Nahualac pond is located on the NW flank of the Iztaccíhuatl volcano at 3900 m asl. This multiproxy investigation integrates the analysis of pollen, non-pollen palynomorphs, diatom…
Long-term vegetation dynamics in a Neotropical coastal mountain
Knowledge of deglacial history in high-altitude environments of the northern Neotropics remains limited, because most research has been focussed on lower elevations. This study presents a palaeoecological reconstruction of vegetation dynamics during the Early to Middle Holocene from a high-elevation peatland (3770 m asl) on Cofre de Perote volcano, located at the eastern end of the Trans-Mexican Volcanic Belt. A sedimentary sequence was analysed …
Environmental changes in central Mesoamerica in the Archaic and Formative periods
This study aims to improve the understanding of climatic fluctuations in the southern Basin of Mexico (BM) during the Archaic (11,500 – 4,000 cal bp ) and Formative (4,000 – 2,000 cal bp ) archaeological periods, when early sedentary settlements at the Zohapilco and Atlapulco sites developed from ∼8,000 – 7,500 cal bp . This study is based on the analysis of diatoms, pollen, microalgae, charcoal, magnetic susceptibility, geochemistry (organic car…
Climate and volcanic impacts on neotropical vegetation over the last 500 years in Mexico
Pollen signal of modern vegetation registered in surface soil samples along an elevation gradient from Iztaccíhuatl volcano, central Mexico
Characterising the vegetation-pollen signal is a crucial task for enhancing the interpretation of fossil pollen records. This study analyses 28 surface soil samples collected in the surroundings of Iztaccíhuatl volcano, between 2,650 and 4,024 m asl. Pollen zones and ordination analysis were assessed to establish a qualitative connection between the pollen signal and the distribution of plant communities along the elevation gradient. The results …
Climatic and anthropogenic influences on vegetation changes during the last 5000 years in a seasonal dry tropical forest at the northern limits of the Neotropics
Seasonal dry tropical forest (STDF) is a widespread vegetation type in western Mexico. Generally, this type of forest develops in semihumid habitats where lacustrine basins are scarce, preventing documentation of the vegetation history and forest dynamics using a paleoecological approach. Here, we present a palynological record from the Santa Maria del Oro crater lake, located within the distribution area of the STDF and the adjacent dry oak fore…
The Holocene history of a tropical high-altitude lake in central Mexico
High-altitude lakes are sensitive to modern and past climate changes. Given their low-water temperatures, alkalinity, and nutrient levels, small climatic differences can strongly affect their water chemistry, and/or biodiversity. In central Mexico, there are only two high-altitude lakes, and both are within the crater of the Nevado de Toluca volcano. Here, we present a paleolimnological record from one of these lakes: La Luna. Previous paleoenvir…
Climatic variability in the northern sector of the American tropics since the latest MIS 3
We inferred millennial-scale climate variations and paleohydrological conditions in the northern sector of the American tropics for 30.3–5.5 cal ka BP using geochemical characteristics of sediments from Lake Chalco in central Mexico. The sediment sequence is chronologically constrainedwith three tephra and nine radiocarbon dates. Temporal variations in titanium, total inorganic carbon, total organic carbon/titanium ratio, carbon/nitrogen ratio, a…
Late Holocene palaeoecology of Lago Verde
Yr of vegetation history of the Upper Lerma, a tropical high-altitude basin in Central Mexico
Pollen analysis on a 9.54-m sediment core from lake Chignahuapan in the upper Lerma basin, the highest intermontane basin in Central Mexico (2570 m asl), documents vegetation and limnological changes over the past ∽23,000 14 C yr. The core was drilled near the archaeological site of Santa Cruz Atizapán, a site with a long history of human occupation, abandoned at the end of the Epiclassic period (ca. 900 AD). Six radiocarbon AMS dates and two wel…
A high-elevation Holocene pollen record from Iztaccihuatl volcano, central Mexico
Pollen data from 3860 m in the Agua El Marrano valley on the northwest side of Iztaccihuatl volcano (southeastern part of the Basin of Mexico, 19N), combined with data on the glacial chronology and tephrochronology, document Holocene climatic and vegetation changes near the present timberline. Glacial advances occurred between 12 000 and-10 500 cal. yr BP (Milpulco-l) and between 8300 and 7300 cal. yr BP (Milpulco-2). A 450-cm core was drilled in…
