High-Up: A Remote Reservoir of Microbial Extremophiles in Central Andean Wetlands [PDF]

open access: yes, 2015
The Central Andes region displays unexplored ecosystems of shallow lakes and salt flats at mean altitudes of 3700 m. Being isolated and hostile, these so-called “High-Altitude Andean Lakes” (HAAL) are pristine and have been exposed to little human ...

Solar and Wind Energy Variability in Tropical South America: Seasonal Ocean‐Atmospheric Modulators

open access: yesMeteorological Applications, Volume 33, Issue 2, March/April 2026.
Climate variability affects renewable energy production and thus considering it in planning is essential for achieving sustainable development. We present how climate (ocean‐atmospheric) variability modes modulate wind and solar radiation variability, thereby influencing renewable power generation in tropical South America. El Niño/Southern Oscillation

Plant clonal morphologies and spatial patterns as self-organized responses to resource-limited environments

open access: yes, 2014
We propose here to interpret and model peculiar plant morphologies (cushions, tussocks) observed in the Andean altiplano as localized structures. Such structures resulting in a patchy, aperiodic aspect of the vegetation cover are hypothesized to self ...

Human adaptation to high‐altitude: A contemporary comparison of the oxygen cascade in Andean, Tibetan and Ethiopian highlanders

open access: yesExperimental Physiology, Volume 111, Issue 3, Page 849-865, 1 March 2026.
Abstract Human populations native to high altitude have evolved distinct physiological adaptations to chronic hypoxia. This adaptation is evident in the O2 transport cascade. In this review, with brief inclusion of the related genetic adaptations, we compare the O2 cascade across three well‐characterized high‐altitude populations: Andeans (Aymara and ...
