Zooplankton of a mountain river and highland bogs in a wetlands complex in Atacama, an Altiplano desert, in northern Ch…
Abstract The Atacama is the world’s driest desert. It contains various types of wetlands. In general, the diversity and structure of the zooplankton in these wetlands have been ve…
Virus and Potential Host Microbes from Viral-Enriched Metagenomic Characterization in the High-Altitude Wetland, Salar …
Salar de Huasco is a wetland in the Andes mountains, located 3800 m above sea level at the Chilean Altiplano. Here we present a study aimed at characterizing the viral fraction an…
Human occupations and climate change in the Puna de Atacama, Chile
Widespread evidence for human occupation of the Atacama Desert, 20° to 25°S in northern Chile, has been found from 13,000 calibrated 14 C year…
Nitrate cycling in Lake Titicaca (Peru-Bolivia): the effects of high-altitude and tropicality
SUMMARY. The vertical distribution of dissolved oxygen and inorganic nitrogen differed considerably between three stratification cycles in Lake Titicaca, a tropical lake (latit…
Seasonal dynamics of nutrient limitation in a tropical high-altitude lake (Lake Titicaca, Peru-Bolivia): Application of…
Five types of physiological assay were applied to samples from three sites in Lake Titicaca, Peru‐Bolivia (16°S), to assess the magnitude and seasonality of N or P limitation of a…
Simulated Small Scale Disturbances Increase Decomposition Rates and Facilitates Invasive Species Encroachment in a High…
AbstractTropical alpine peatlands are important carbon reservoirs and are a critical component of local hydrological cycles. In high elevation peatlands slow decomposition rates r…
In-stream wetland deposits, megadroughts, and cultural change in the northern Atacama Desert, Chile
AbstractA key concern regarding current and future climate change is the possibility of sustained droughts that can have profound impacts on societies. As such, multiple paleoclim…
A Model for Estimating the Vegetation Cover in the High-Altitude Wetlands of the Andes (HAWA)
The natural salt meadows of Tilopozo in the hyperarid, Atacama Desert of northern Chile, which are located at approximately 2800 m above sea level, are under pressure from industr…
Peatlands of the Peruvian Puna ecoregion: types, characteristics and disturbance
Peatlands represent one of the most important water resources in the Puna grassland ecoregion, but this fact is not yet widely recognised. Puna peatlands also provide key environm…
Long-term monitoring of tropical alpine habitat change, Andean anurans, and chytrid fungus in the Cordillera Vilcanota,…
AbstractThe Cordillera Vilcanota in southern Peru is the second largest glacierized range in the tropics and home to one of the largest high‐alpine lakes, Sibinacocha (4,860 m). H…
Spectroscopic Assessment of Soil Organic Matter in Wetlands from the High Andes
Wetlands are valuable for their function as C sinks, water conservation and filtering, flood control, and as a recreational landscape. In the Central and Sout…
Mapping hazards from glacier lake outburst floods based on modelling of process cascades at Lake 513, Carhuaz, Peru
Abstract. Recent warming has had enormous impacts on glaciers and high-mountain environments. Hazards have changed or new ones have emerged, including those from glacier lakes tha…
A high-altitude peatland record of environmental changes in the NW Argentine Andes (24 ° S) over the last 2100 years
Abstract. High-altitude cushion peatlands are versatile archives for high-resolution palaeoenvironmental studies, due to their high accumulation rates, range of proxies, and sensi…
Predicting outflow induced by moraine failure in glacial lakes: the Lake Palcacocha case from an uncertainty perspective
Abstract. Moraine dam collapse is one of the causes of glacial lake outburst floods. Available models seek to predict both moraine breach formation and lake outflow. The models de…
Paleoindian settlement of the high-altitude Peruvian Andes
Mountain dwellers of the Pleistocene Humans colonized the inhospitable high Andes at least 11.5 thousand years ago. Rademaker et al. …
Direct and indirect effects of glaciers on aquatic biodiversity in high Andean peatlands
AbstractThe rapid melting of glacier cover is one of the most obvious impacts of climate change on alpine ecosystems and biodiversity. Our understanding of the impact of a decreas…
Chromohalobacter nigrandesensis sp. nov., a moderately halophilic, Gram-negative bacterium isolated from Lake Tebenquic…
A total of 52 strains of moderately halophilic bacteria isolated from hypersaline sediment of Lake Tebenquiche on the Atacama Saltern, Chile, were subjected to a taxonomic study. …
Hydrological differentiation and spatial distribution of high altitude wetlands in a semi-arid Andean region derived fr…
Abstract. High Altitude Wetlands of the Andes (HAWA) belong to a unique type of wetland within the semi-arid high Andean region. Knowledge about HAWA has been derived mainly from …
Modelling beta diversity of aquatic macroinvertebrates in High Andean wetlands
<p>Central Andean Highlands represent a singular environment characterized by various extreme conditions. Among them, peatbogs are exceptional marshy habitats scattered thro…
Zooplankton of a mountain river and highland bogs in a wetlands complex in Atacama, an Altiplano desert, in northern Ch…
The Atacama “puna” (high-altitude plateau) is situated among the high peaks of the Andes at over 4000 m a.s.l. This ecosystem covers parts of north-eastern Chile, north-western Ar…
