Multi-century lake area changes in the Southern Altiplano: a tree-ring-based reconstruction
Abstract. Size fluctuations in endorheic lakes in northwestern Argentina (NWA) and southwestern Bolivia (SWB) are very sensitive to basin hydrological balances, and consequently, …
Microbial diversity in Maras salterns, a hypersaline environment in the peruvian andes.
ABSTRACTMaras salterns are located 3,380 m above sea level in the Peruvian Andes. These salterns consist of more than 3,000 little ponds which are not interconnected and act as cr…
Late Holocene environmental changes reconstructed from stable isotope and geochemical records from a cushion-plant peat…
ABSTRACTA Late Holocene paleoenvironmental record was obtained from the Lagunillas cushion peatland (LP, 27°12′S, 69°17′W), located in the dry Puna of the western Central Andes. T…
Methane Emissions from a Grassland-Wetland Complex in the Southern Peruvian Andes
Abstract. A 58 hectare mixed upland and lowland boreal plains watershed called the Sandhill Fen Watershed was constructed between 2008 and 2012. In the years following wetting in …
Fish-flamingo-plankton interactions in the Peruvian Andes
The zooplankton and flamingo populations of 20 high elevation (3,700–4,700 m) lakes in the Andes of southern Peru were assessed on one to three occasions each. Some of these lakes…
Wilson's Phalarope in the Central Andes and its Interaction with the Chilean Flamingo
The geological development of the basement of the Argentinian/Chilean Andes during the Palaeozoic is characterized by an almost continuous structural, metamorphic and plutonic mob…
Impact of a rock avalanche on a moraine-dammed proglacial lake: Laguna Safuna Alta, Cordillera Blanca, Peru
AbstractMoraines that dam proglacial lakes pose an increasing hazard to communities in the Andes and other mountain ranges. The moraines are prone to failure through collapse, ove…
Multidate, multisensor remote sensing reveals high density of carbon-rich mountain peatlands in the páramo of Ecuador
AbstractTropical peatlands store a significant portion of the global soil carbon (C) pool. However, tropical mountain peatlands contain extensive peat soils that have yet to be ma…
Carbon storage and long-term rate of accumulation in high-altitude Andean peatlands of Bolivia.
1. (1) The high-altitude (4,500+ m) Andean mountain range of north-western Bolivia contains many peatlands. Despite heavy grazing pressure and potential damage from climate change…
The effects of check dams and other erosion control structures on the restoration of Andean bofedal ecosystems
AbstractRestoring degraded lands in rural environments that are heavily managed to meet subsistence needs is a challenge due to high rates of disturbance and resource extraction. …
Glacial areas, lake areas, and snow lines from 1975 to 2012: status of the Cordillera Vilcanota, including the Quelccay…
Abstract. Glaciers in the tropical Andes of southern Peru have received limited attention compared to glaciers in other regions (both near and far), yet remain of vital importance…
Long-term limnological changes in the Ecuadorian páramo: Comparing the ecological responses to climate warming of shall…
AbstractPáramos are high‐altitude ecosystems of grasslands and shrubs that sustain high levels of biodiversity and contain numerous lakes, ponds and wetlands that are a crucial so…
Characterization of cyanobacterial communities from high ‐ elevation lakes in the Bolivian Andes
The Bolivian Altiplano is a harsh environment for life with high solar irradiation (visible and UVR), below freezing temperatures, and some of the lowest precipitation rates on th…
Diverse responses to UV-B radiation and repair mechanisms of bacteria isolated from high-altitude aquatic environments
ABSTRACT Acinetobacter johnsonii A2 isolated from the natural community of Laguna Azul (Andean Mountains at 4,560 m above sea level), …
Impact of solar radiation on bacterioplankton in Laguna Vilama, a hypersaline Andean lake (4650 m)
Laguna Vilama is a hypersaline Lake located at 4660 m altitude in the northwest of Argentina high up in the Andean Puna. The impact of ultraviolet (UV) radiation on bacterioplankt…
Rapid development of an unusual peat-accumulating ecosystem in the Chilean Altiplano
AbstractStratigraphic relationships, radiocarbon dating, sediment and peat characteristics, and rates of peat and carbon accumulation from a soligenous peatland, or “bofedal,” in …
Diversity of Bacteroidetes in high-altitude saline evaporitic basins in northern Chile
The phylum Bacteroidetes represents one of the most abundant bacterial groups of marine and freshwater bacterioplankton. We investigated the diversity of Bacteroidetes in water an…
Two Thousand Years of Land-Use and Vegetation Evolution in the Andean Highlands of Northern Chile Inferred from Pollen …
The European conquest of the New World produced major socio-environmental reorganization in the Americas, but for many specific regions and ecosystems, we still do not understand …
Seasonal activity patterns and abundance of Andean flamingo (Phoenicoparrus Andinus) at two contrasting wetlands in Arg…
Flamingos are gregarious birds that live in brackish lakes. During winter, Andean Flamingo (Phoenicoparrus andinus) and Chilean Flamingo (Phoenicopterus chilensis) inhabit shallow…
