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...
Esta obra reúne los trabajos presentados por un grupo de especialistas a las lIlas. Jornadas Antárticas y del Medio Ambiente, efectuadas entre el 11 y 15 de Noviembre de 1991 en la ciudad de Punta Arenas, Chile.
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...
The causes of Late Pleistocene megafaunal extinctions (60,000 to 11,650 years ago, hereafter 60 to 11.65 ka) remain
contentious, with major phases coinciding with both human arrival and climate change around the world. The
Americas provide a unique opportunity to disentangle these factors as huma...
The Antarctic Roadmap Challenges (ARC) project identified critical requirements to deliver high
priority Antarctic research in the 21st century. The ARC project addressed the challenges of enabling
technologies, facilitating access, providing logistics and infrastructure, and capitalizing on inte...
Los osos de agua o tardígrados, son criaturas cuya característica radica en su poder de resistencia ante ambientes o climas extremos. A pesar de su diminuto tamaño, esta especie ha dado ejemplo de supervivencia y resistencia a diferencia de otras especies que cohabitan en el reino animal. Tales c...
