Composition, diversity and size of diatoms consumed by the Andean Flamingo (Phoenicoparrus andinus) in Salar de Punta Negra, Antofagasta Region, Northern Chile
(2012)
In April 2009, at the Salar de Punta Negra (24°35'S, 68°58'W) in the Antofagasta Region of northern Chile, we quantified the composition, diversity, and size of diatoms, the only consumed prey by both adults and nestlings ...
Spatial and Temporal Ecological Uniqueness of Andean Diatom Communities Are Correlated With Climate, Geodiversity and Long-Term Limnological Change
(Frontiers Media, 2020)
High-elevation tropical lakes are excellent sentinels of global change impacts, such as climate warming, land-use change, and atmospheric deposition. These effects are often correlated with temporal and spatial beta diversity ...
Nuclear Fukui functions from nonintegral electron number calculations
(2007)
Numerical results for the nuclear Fukui function (NFF) based on a nonintegral number of electrons methodology (NIEM) are reported for a series of simple diatomic molecules. A comparison with those obtained from other ...
Geothermal diatoms: seasonal variability in the El Tatio geothermal field (Altiplano, Chile)
(Scientific Research Publishing, 2018)
Diatom floras were examined in a high-altitude geothermal field, 4200 - 4500 m (29 degrees 19'S 68 degrees W'), located in the Central Andean dry Puna ecoregion or southern Altiplano. These locations include hostile ...
Spatio temporal population dynamics of the invasive diatom Didymosphenia geminata in central-southern Chilean rivers
(Elsevier, 2016)
We document the distribution of Didymosphenia geminata in central-southern Chilean rivers and identify the chemical and physical factors associated with its presence/absence (p/a). Repeated surveys in five successive years ...
Differentiation of Diatom Guilds in Extreme Environments in the Andean Altiplano
(Frontiers Media, 2021)
The Andean Altiplano is characterized by its isolation, high altitude (> 3,600 m a.s.l.), and a unique biodiversity, containing water systems such as lakes, rivers, wetlands, and salt flats. Near the southernmost area of ...
Early to mid-Holocene aridity in central Chile and the southern Westerlies: The Laguna Aculeo record (34°S)
(Academic Press Inc., 2002)
Central Chile (32-35°S) lies at the northern border of strong Westerly influence and thus exhibits a steep precipitation gradient. Therefore, the palaeoclimatic archives in the region are suitable for detecting past moisture ...
On the variational solution of morphed molecular potential in a diatomic molecule
(Springer, 2013)
The general one-dimensional potential energy function, including centrifugal
distortion, for a diatomic molecule is morphed with a series of Morse-like
functions for each of the rotational quantum numbers J . For each ...
Amplicon metagenomic analysis of fungi from Antarctic Terrestrial habitats
(Frontiers Media, 2017)
In cold environments such as polar regions, microorganisms play important ecological roles, and most of our knowledge about them comes from studies of cultivable microorganisms. Metagenomic technologies are powerful tools ...
Epilithic diatom flora in Cali River hydrographical basin, Colombia
(2019)
This research aimed to study the composition of epilithic diatom flora found in samples collected in Cali River hydrographical basin, Colombia. Quarterly excursions (March, June, September and December of 2012 and March ...
