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 …
Climatic response of Juniperus monticola Martinez, a multi-century alpine shrub from the high mountains of central Mexico
The mountain juniper Juniperus monticola Martinez, a decumbent alpine shrub found at elevations up to 4600 m a.s.l. on the high mountains of central Mexico, is the woody species growing at highest elevation in North America. It reaches an age close to a millenium, which probably makes it the oldest alpine shrub in the world. We conducted a dendrochronological study of this species at Pico de Orizaba volcano, the highest peak in Mexico, to analyze…
Using dendrogeomorphic and lichenometric approaches for rockfall analysis in the high mountains of Central Mexico
Rockfall represents one of the most destructive geomorphic processes for infrastructure and settlements located at the foot of mountain slopes. Furthermore, it poses a hazard for visitors and hikers. Despite the high anthropic activity in these environments, research on the reconstruction of rockfall in the high mountains of Mexico is still scarce. We used dendrochronological, dendrogeomorphological and lichenometric approaches to study the age a…
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 …
Effects of human occupation on soil loss over the past two millennia in the Teotihuacan Valley, central Mexico
Soil erosion is one of the greatest risks worldwide for land degradation. Avoiding it is one of the greatest socio-environmental and economic challenges within sustainable development in connection with food production and maintenance of soil functions in the context of climate change. This study will allow us to answer how long-term occupation dynamics influenced by notable changes in the landscape have led to soil erosion through time. We used …
Past and future sky-island dynamics of tropical mountains
Recent collecting and taxonomic studies of dung beetles of the genus Geotrupes Latreille (Coleoptera: Geotrupidae) in the mountains of Oaxaca have evidenced the existence of a vicariant speciation pattern, where one species occupies the northern mountain system and the other one the southern mountain range. A study of this possible vicariant speciation mechanism is presented using a paleobiogeographic mapping analysis of both Geotrupes species di…
A preliminary investigation of the timing of the local last glacial maximum and deglaciation on HualcaHualca volcano - Patapampa Altiplano (arid Central Andes, Peru)
Rates of pedogenic processes in volcanic landscapes of late Pleistocene to Holocene age in Central Mexico
Last Glacial Maximum and deglaciation of Sierra de Gredos, central Iberian Peninsula
Tree-ring reconstruction of past lahar activity at Popocatépetl volcano, Mexico
Lahars represent a major threat on the slopes of volcanoes all over the world. In order to realistically assess hazards, knowledge on the occurrence and timing of past lahar activity is of crucial importance. However, archival data on past events is usually scarce or completely missing. Tree-ring records have repeatedly proved to be a reliable data source for the reconstruction of past geomorphic events. However, tree rings have seldom been appli…
Multiple Dendrochronological Signals Indicate the Eruption of ParíCutin Volcano, Michoacán, Mexico
The eruption of Parícutin (1943–1952), a cinder cone volcano in Michoacán, Mexico, caused dendrochronological and dendrochemical responses that might be useful as general dating tools for eruptions. For the eruption period, pines near Parícutin have slightly suppressed ring widths plus high inter-annual variability of width. Wood anatomy changes include traumatic resin ducts and thin bands of false latewood. Dendrochemistry of tree rings shows li…
