Evolution of ice-dammed proglacial lakes in Última Esperanza, Chile: Implications from the late-glacial R1 eruption of Reclús volcano, Andean Austral Volcanic Zone Evolución de lagos proglaciales embalsados por hielo en Última Esperanza, Chile: Implicanci
(2011)
Newly described outcrops, excavations and sediment cores from the region of Última Esperanza, Magallanes, contain tephra derived from the large late-glacial explosive R1 eruption of the Reclús volcano in the Andean Austral ...
Physicochemical Parameters Affecting the Distribution and Diversity of the Water Column Microbial Community in the High-Altitude Andean Lake System of La Brava and La Punta
(MDPI, 2020)
Due to the low incidence of precipitation attributed to climate change, many high-altitude Andean lakes (HAALs) and lagoons distributed along the central Andes in South America may soon disappear. This includes La Brava-La ...
Bacterioplankton composition in tropical high elevation lakes of the Andean plateau
(Oxford University Press, 2018)
High-elevation lakes in the tropics are subject to extreme environmental fluctuations and microbes may harbor a unique genomic repertoire, but their composition and diversity are largely unknown. Here, we compared the ...
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 ...
Phytoplankton and zooplankton response to ultraviolet radiation in a high-altitude Andean lake: Short- versus long-term effects
(Oxford University Press, 1997)
Exclusion experiments on global UV (A and B) radiation and global UVB were performed
in 460 1 mesocosms with plankton communities from the oligotrophic Andean lake Laguna Negra
(33°35'S-70°04'W; 2700 m a.s.1.). The ...
Two new Liolaemus lizards from the Andean highlands of Southern Chile (Squamata, Iguania, Liolaemidae)
(Pensoft Publishers, 2016)
Liolaemus is a diverse genus of lizards, subdivided into two subgenera: Liolaemus (sensu stricto) and Eulaemus, distributed mainly in Chile and Argentina. The L. elongatus-kriegi complex is the most diverse group within ...
Timing and structure of vegetation, fire, and climate changes on the Pacific slope of northwestern Patagonia since the last glacial termination
(Elsevier, 2020)
By virtue of its location in the southern mid-latitudes, northwestern Patagonia (40 degrees-44 degrees S) offers the opportunity to unravel the mechanisms involved in the initiation and propagation of paleoclimate signals ...
Miscanti-1: Human occupation during the arid Mid-Holocene event in the high-altitude lakes of the Atacama Desert, South America
(Pergamon-Elsevier Science LTD, 2018)
This paper presents an interdisciplinary study of the Miscanti-1 archaeological site, located in the Holocene terrace deposits accumulated on the eastern margin of Miscanti Lake (4120 m.a.s.1.), northern Chile (23.7 degrees ...
Climate changes and recent glacier behaviour in the Chilean Lake District
(ELSEVIER SCIENCE BV, 2007-10)
Atmospheric temperatures measured at the Chilean Lake District (38°–42°S) showed contrasting trends during the second half of the
20th century. The surface cooling detected at several meteorological stations ranged from ...
Andean high-altitude ancestry does not protect from acute mountain sickness and altitude-induced arterial hypoxemia
(Interciencia Association, 2017)
It is thought that adaptive changes protect high-altitude populations against altitude-induced diseases, but information from well controlled studies is lacking. In a prospective, controlled study, we assessed the prevalence ...
