Metal leaching, acidity, and altitude confine benthic macroinvertebrate community composition in Andean streams
(Wiley, 2014)
Andean streams drain metal-rich bedrock and are subjected to an extreme altitude gradient, which may create highly selective conditions for life. The aim of the present study was to evaluate the combined effects of metals ...
The effect of inositol hexaphosphate in the high-affinity hemoglobin of the Andean chicken (Gallus gallus)
(Elsevier, 1994)
A strain of high-altitude chickens (Gallus gallus) with a high hemoglobin-oxygen affinity has been found in the Peruvian Andes. The purpose in this work was to investigate the relation of this high affinity with the ...
Global Research Expedition on Altitude-related Chronic Health 2018 Iron Infusion at High Altitude Reduces Hypoxic Pulmonary Vasoconstriction Equally in Both Lowlanders and Healthy Andean Highlanders
(Elsevier, 2022)
Background: Increasing iron bioavailability attenuates hypoxic pulmonary vasoconstriction in both lowlanders and Sherpas at high altitude. In contrast, the pulmonary vasculature of Andean individuals with chronic mountain ...
Global Research Expedition on Altitude-related Chronic Health 2018 Iron Infusion at High Altitude Reduces Hypoxic Pulmonary Vasoconstriction Equally in Both Lowlanders and Healthy Andean Highlanders.
(Elsevier, 2021)
BACKGROUND: Increasing iron bioavailability attenuates hypoxic pulmonary vasoconstriction in both lowlanders and Sherpas at high altitude. In contrast, the pulmonary vasculature of Andeans with chronic mountain sickness ...

High-Altitude Andean H194R HIF2A Allele Is a Hypomorphic Allele
(Oxford University Press, 2023)
For over 10,000 years, Andeans have resided at high altitude where the partial pressure of oxygen challenges human survival. Recent studies have provided evidence for positive selection acting in Andeans on the HIF2A (also ...
Temperature regime influences accessions and effectiveness of germination promoters in the high-Andean crop maca
(Wiley, 2021)
High-Andean crops are precious resources for low-income farmers threatened by climate conditions. In the Puna region of the central Peruvian Andes, poor farmers grow maca (Lepidium meyenii Walpers), a root crop endemic to ...
