Edaphic and light conditions of sympatric plant morphotypes in western Amazonia
Here I present a dataset of edaphic and light conditions associated with the occurrence of sympatric morphotypes of Geonoma macrostachys (Arecaceae/Palmae), a candidate case study…
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…
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…
