Effect of altitude on mortality of end-stage renal disease patients on hemodialysis in Peru
(Universidad Continental, 2021)
Background. In Latin America, the prevalence of end-stage kidney disease (ESKD) has risen tremendously during the last
decade. Previous studies have suggested that receiving dialysis at high altitude confers mortality ...
Altitude and temperature drive anuran community assembly in a Neotropical mountain region
(2022-01-01)
Understanding the spatial variation in species richness and the mechanisms that limit species range sizes along geographical gradients belong to the central research issues in macroecology. Here, we aim to test the topographic ...

High altitude, hyper‑arid soils of the Central‑Andes harbor mega‑diverse communities of actinobacteria
(Springer Japan KK, 2018)
The data reported in this paper are among the first relating to the microbiology of hyper-arid, very high altitude deserts and they provide base line information on the structure of actinobacterial communities. The high ...
Persea pumila (Lauraceae), a New Species from the Brazilian Serra da Mantiqueira Mountain Range
(Amer Soc Plant Taxonomists, 2014-04-01)
Persea pumila, a new species of Lauraceae from a Brazilian high-altitude grassland is described and illustrated. The new species belongs to Parses subg. Eriodaphne. It is distinguished from other neotropical Persea species ...
Wood-decaying polypores in the mountains of central Argentina in relation to Polylepis forest structure and altitude
(Elsevier, 2010-08)
To determine how altitude and forest successional stage are related to richness and composition of wood-decaying polypore fungi in Polylepis mountain forests of central Argentina we sampled 48 forest plots of 900 m2 which ...
Low‐altitude meteor trail echoes
(American Geophysical Union, 2009-11-12)
We present here the first observations of a new type of meteor echo. These Low‐Altitude Trail Echoes (LATE), observed almost exclusively below 90 km altitude using the Jicamarca Research Observatory 50 MHz radar, exhibit ...
Ecologia de invertebrados aquáticos em riachos de altitude do planalto de Poços de Caldas, MG, Brasil
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERNCâmpus São Carlos, 2018-03-08)
Streams are unique and isolated environments that include a wide range of species. These
species have close relations with these ecosystems and may have different patterns of
ecological responses. Thus, this study compared ...

Lithium in drinking water, altitude, and suicide rates in rural areas of Argentinean Andes
(Elsevier, 2021-02)
The Lithium Triangle in the Andean plateau involves high altitude (>3,000 m asl) hydrological systems having high lithium graded waters. This research was carried-out in rural areas of north westernmost Argentinean Andes ...
