Abundance and Habitat of High Andes Flamingos in Northwestern Argentina
Three flamingo species occur in the High Andes wetlands of Argentina, Bolivia, Chile, and Peru: James (Phoenicoparrusjamesi), Andean (P. andinus), and Chilean, (Phoenicopterus chi…
Interannual lake fluctuations in the Argentine Puna: relationships with its associated peatlands and climate change
High elevation ecosystems are likely more sensitive to climate change. But, due to paucity of instrumental records, such effects are poorly studied, particularly in mountains outs…
Solute inputs in the Salar de Atacama (N. Chile)
The provenance of saline inputs to the Salar de Atacama has been studied by means of the isotopic composition of sulphates dispersed in drilling core samples and the analysis of t…
An integrated socio-environmental framework for glacier hazard management and climate change adaptation: lessons from L…
Glacier hazards threaten societies in mountain regions worldwide. Glacial lake outburst floods (GLOFs) pose risks to exposed and vulnerable populations and can be linked in part t…
Living and dying with glaciers: people's historical vulnerability to avalanches and outburst floods in Peru
Human populations worldwide are vulnerable to natural disasters. Certain conditions—such as geographical location or people’s income level—can affect the degree to which natural d…
Guanacos in the Desert Puna: A trade-off between drinking and the risk of being predated
Habitats vary not only in resource availability and quality but also in predation risk, among other factors. The Desert Puna of Argentina comprises two habitats: the shrub steppe …
The High-Lakes Project
The High Lakes Project is a multidisciplinary astrobiological investigation studying high-altitude lakes between 4200 m and 6000 m elevation in the Central Andes of Bolivia and Ch…
Models as multiple working hypotheses: hydrological simulation of tropical alpine wetlands
Tropical alpine grasslands, locally known as p ́ aramos, are the water towers of the northern Andes. They are an essential water source for drinking water, irrigation schemes and h…
Ecology of a paramo cushion mire
A pollen diagram of a 225 cm long core from a small Plantago rigida cushion mire (Turbera de Calostros) in the grassparamo belt at 3730m altitude in the Paramo de Chingaza, Easter…
Holocene mire development and climatic change from a high Andean Plantago rigida cushion mire
A pollen diagram of a 225 cm long core from a small Plantago rigida cushion mire (Turbera de Calostros) in the grassparamo belt at 3730m altitude in the Paramo de Chingaza, Easter…
A phytoremediation approach using Calamagrostis ligulata and Juncus imbricatus in Andean wetlands of Peru
Emergent plant species growing in Andean natural wetlands have shown efficient phytoremediation capabilities in wetlands polluted by acid mine drainage. However, the types and amo…
Using Foresight to Gain a Local Perspective on the Future of Ecosystem Services in a Mountain Protected Area in Peru
Ecosystem services in the mountainous Salinas and Aguada Blanca National Reserve in Peru are under pressure, and perspectives on possible solutions depend on the different stakeho…
The influence of climate change on recent peat accumulation patterns of Distichia muscoides cushion bogs in the high-el…
extensive cushions of Distichia muscoides found at high elevations in the Andes form deep deposits of peat and function as peatland. The location of Distichia peatlands at the hig…
Response curves and the environmental limits for peat-forming species in the northern Andes
Peatlands, with organic soils, are usually dominated by one or a few species. Above and belowground ecological processes are regulated by the characteristics of the dominant speci…
The effect of drainage on organic matter accumulation and plant communities of high-altitude peatlands in the Colombian…
The tropical Andes store and regulate water outflow that serves nearly 60 million people. Most of the water is for un-managed agricultural irrigation. In this work I report how th…
Short-Term Effects of Pack Animal Grazing Exclusion from Andean Alpine Meadows
Grazing by livestock can have positive, neutral, and/or negative effects on vegetation depending on the intensity and type of grazing. This includes grazing by pack animals used f…
Evolution of High Andean Puna Ecosystems: Environment, Climate, and Culture Change over the Last 12,000 Years in the Ce…
In the High Andes, much of the traditional knowledge related to natural resource utilization and agricultural practices was lost with the arrival of the Spaniards. That which has …
Monitoring Andean high altitude wetlands in central Chile with seasonal optical data: A comparison between Worldview-2 …
In the Maipo watershed, situated in central Chile, mining activities are impacting high altitude Andean wetlands through the consumption and exploitation of water and land. As wet…
