La presente investigación histórica tiene por objeto realizar una aproximación al contexto en que se hallaba la Antártica en los inicios del siglo XX, centrándose en la expedición del capitán Robert Falcon Scott y su propósito de llegar al Polo Sur Geográfico en el contexto de la Carrera Polar. F...

The following piece of historic research has the goal of approaching the context surrounding the Antarctic at the beginning of the 20th century, with a focus on captain Robert Falcon Scott’s expedition and his intention to reach the geographical South Pole in the framework of the race to the pole...


The macrobenthic community of the Straits of Magellan and the Beagle Channel was investigated using a Reineck box corer at 22 stations during the Chilean “Cimar Fiordo 3” expedition in 1997. A total of 173 taxa represented by 2188 individuals were identified and are reported for the investigated ...

En octubre 1997 se investigaron los ensambles macrozoobentónicos del estrecho de Magallanes y el canal Beagle con un “Reineck Box corer” en 22 estaciones durante la campaña chilena “Cimar Fiordo 3”. Se identificó un total de 173 taxones representados por 2188 especímenes en el area de investigaci...


The Western Antarctic Peninsula (WAP) has undergone significant changes in air and seawater temperatures during the last 50 years. Although highly stenotherm Antarctic organisms are expected to be severely affected by the increase of seawater temperature, high-resolution datasets of seawater temp...


Antarctic climate is challenging, since the cold, wind and sensory monotony are stressful stimuli to individuals. Moreover, camp activities and heavy clothes may contribute to increase physiological strain. Thus, we aimed to characterise the physiological demand of a 24-day period in the Antarcti...


Endophytic fungi form mutualistic associations with plant roots which can increase plant survival and resistance to stress. Recently, it has been proposed that endophytic fungi from Antarctica should be used to facilitate reintroduction and establishment of native plants in xeric environments of ...

Los hongos endófitos forman asociaciones mutualísticas con raíces de plantas y pueden mejorar la sobrevivencia y resistencia al estrés. Recientemente se ha propuesto usar hongos endófitos de la Antártida para facilitar la reintroducción y establecimiento de plantas nativas en formaciones xerofíti...


El presente trabajo se propone analizar los significados de las palabras que designan o se refieren a aspectos del mundo antártico. Esto es, nombres que designen a paisajes, personas, actividades, objetos y acontecimientos. Se trata de analizar los cambios semánticos, que afectan a la lengua espa...

This paper analyzes the meaning and implication of words used to describe Antarctic-related phenomena from the landscape and physical objects to the individuals stationed there, their activities, and their interaction. Attention is paid to how those individuals have semantically transformed the S...


Background: Early life stages of macroalgae, especially from polar species, can be highly vulnerable to physical stressors, leading to important consequences for the fate of the whole population in scenarios of changing environmental variability. In the present study, tolerance to UV and temperat...


Dos informes recientemente publicados documentan el pasado y presente, y las predicciones futuras para el clima sobre la Antártica y el Océano Austral. De estas síntesis es claro que Antártica juega un rol crítico en el cambio climático sufrido a nivel hemisférico y regional, y que las actividade...

Two recently released reports document the past, present and future predictions for climate over the Antarctic and the Southern Ocean. From these syntheses it is clear that the Antarctic plays a critical role in hemispheric to regional climate change and that in recent times human activities are ...


Background: Maritime Antarctica is severely affected by climate change and accelerating glacier retreat forming temporal gradients of soil development. Successional patterns of soil development and plant succession in the region are largely unknown, as are the feedback mechanisms between both pro...
