Prokaryotic diversity pattern in high-altitude ecosystems of the Chilean Altiplano
The Chilean Altiplano is the westernmost part of a large volcanic‐sedimentary plateau in the central Andes. High solar irradiance and rapid increase of temperature have contribute…
Nurse species and indirect facilitation through grazing drive plant community functional traits in tropical alpine peat…
AbstractFacilitation among plants mediated by grazers occurs when an unpalatable plant extends its protection against grazing to another plant. This type of indirect facilitation …
Drivers of Peatland Water Table Dynamics in the Central Andes, Bolivia and Peru
AbstractCushion plant dominated peatlands are key ecosystems in tropical alpine regions of the Andes in South America. The cushion plants have formed peat bodies over thousands of…
Effects of grazing pressure on plant species composition and water presence on bofedales in the Andes mountain range of…
Bofedales are high-Andean peatland plant communities with high capacity for water retention, which are regarded as oases of biodiversity. These areas have great social and economi…
Long-term carbon accumulation in two tropical mountain peatlands, Andes Mountains, Ecuador
Tropical peatlands form in at least two distinct altitudinal zones, namely lowlands and high mountains. Unlike lowland tropical peatlands, which are typically…
A Multiscale Productivity Assessment of High Andean Peatlands across the Chilean Altiplano Using 31 Years of Landsat Im…
The high Andean peatlands, locally known as “bofedales”, are a unique type of wetland distributed across the high-elevation South American Altiplano plateau. This extensive peatla…
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 …
