Antarctica is an iconic region for scientific explorations as it is remote and a critical component of the global climate system. Recent climate change causes a dramatic retreat of ice in Antarctica with associated impacts to its coastal ecosystem. These anthropogenic impacts have a potential to ...
Most of the ice and snow-free land in the Antarctic summer is found along the Antarctic Peninsula and adjacent islands and coastal areas of the continent. This is the area where most of the Antarctic vegetation is found. Mean air temperature tends to be above zero during the summer in parts of th...
El presente artículo se refiere a las sucesivas exploraciones realizadas por integrantes del Ejército de Chile hacia el interior del continente antártico entre los años 1992 y 1996, actividades que permitieron que un equipo de la Escuela de Montaña conquistara el Polo Sur Geográfico, esquiando. E...
This article refers to the successive explorations performed by members of the Chilean Army into the Antarctic Continent between the years 1992 - 1996, activities that allowed a mountain school team conquered the geographic South Pole. The author of this article served as chief of the Army's firs...
The biogeography and ecology of decapod crustaceans was described for the higher latitudes of the Southern
Ocean. The analyzed area included the transitional or antiboreal region of the South American continental shelves (south of
about 42°30’S), the Antarctic continental shelves, the Subantarcti...
Se describe
la biogeografía y ecología de crustáceos decápodos para altas latitudes del Océano Austral. El área analizada incluye
la región antiboreal de las plataformas continentales sudamericanas (sur de 42º30’S), las plataformas continentales antárticas,
las islas de los Archipiélagos de Escoc...
Background: Photosynthetic characteristics and the effect of UV radiation and elevated temperature measured
were studied in Chlorella sp. isolated from a snow microalgal community at King George Island, Maritime Antarctica
through the chlorophyll florescence (rapid light curves and maximum quantu...
El conocimiento actual de los cambios climáticos que han ocurrido en los últimos 50 años sobre la Antártica se presenta con un enfoque sobre: (i) un calentamiento de verano de la región oriental de la Península Antártica, lo que provocó el colapso de la plataforma de hielo Larsen B, (ii) la obser...
The current understanding of climate changes that have occurred in the last 50 years over Antarctica is presented with a focus on: (i) a summer warming of the eastern Antarctic Peninsula, which caused the collapse of the Larsen B ice shelf, (ii) the observed significant increase of total sea ice ...
After the finding of anti-Brucella antibodies in samples of Antarctic fur seal (Arctocephalus gazella), the serological study on Antarctic Pinniped was continued in order to determine the presence of anti-Brucella antibodies in other species. Blood and extra vascular fluid samples were taken from...
Posterior al hallazgo de anticuerpos anti-Brucella en muestras de lobo fino antártico (Arctocephalus gazella), el estudio serológico en Pinnipedia Antárticos se continuó con el fin de determinar la presencia de anticuerpos anti-Brucella en otras especies. Se colectaron muestras de sangre y de flu...
The long-term socio-ecological research (LTSER) study sites should integrate theoretical and applied research to effectively confront global socio-environmental change. For a socio-ecological integration beyond the socio-economic approach that prevails today in
LTSER networks worldwide, in the so...
Los sitios de estudios socio-ecológicos a largo plazo (LTSER) debieran integrar investigación teórica y aplicada para confrontar efectivamente el cambio socio-ambiental global. Para lograr una integración socio-ecológica que vaya más allá del enfoque socioeconómico que prevalece hoy en las redes ...
El conocimiento taxonómico de la flora marina bentónica de la región austral de Sudamérica, incluida
la Antártica, está basado fundamentalmente en los registros de las expediciones europeas que recorrieron
los mares australes durante los siglos XVIII, XIX y principios del siglo XX. Debido a la le...
Knowledge of the benthic marine flora from southern South America, and Antarctica is based
on past centuries of exploration of the region by early naturalists. Lack of accessibility to the area has
been a limiting factor in carrying out a critical revision of these early records reported in the l...
