FP7: Research on climate change in polar environments must include effects on biota of both polar regions
Read more of: FP7: Research on climate change in polar environments must include effects on biota of both polar regionsPolar biology is on the threshold of a revolution based on new technologies (e.g. genomics, proteomics), which will greatly enhance our knowledge of polar ecosystems and their biodiversity. The broad […]

Divergent flow of the West Antarctic Ice Sheet on the outer contintental shelf of the Amundsen Sea during the late Quaternary
Read more of: Divergent flow of the West Antarctic Ice Sheet on the outer contintental shelf of the Amundsen Sea during the late QuaternarySummary Understanding the past glacial history of regions undergoing potential rapid deglaciation is essential in order to estimate the possible threat of sea level rise. Recently acquired data have given […]

Antarctic marine biodiversity challenged by global change: the CAML/SCAR-MarBIN benchmark
Read more of: Antarctic marine biodiversity challenged by global change: the CAML/SCAR-MarBIN benchmarkThere is now undisputed evidence that climate change and modifications of the Earth system occurs, at faster rates in the polar regions. Among the many consequences we will be facing, […]

On the fractal nature of the magnetic field energy density in the solar wind
Read more of: On the fractal nature of the magnetic field energy density in the solar windThe solar wind exhibits scaling typical of intermittent turbulence in the statistics of in situ fluctuations in both the magnetic and velocity fields. Intriguingly, quantities not directly accessed by theories […]

Life history adaptations to polar and alpine environments
Read more of: Life history adaptations to polar and alpine environmentsThis chapter is concerned with the life-history features of terrestrial invertebrates inhabiting the cold regions of the world. It predominantly focuses on the Antarctic continent and the Arctic elements of […]

Ecological relevance of laboratory determined temperature limits: colonization potential, biogeography and resilience of Antarctic invertebrates to environmental change
Read more of: Ecological relevance of laboratory determined temperature limits: colonization potential, biogeography and resilience of Antarctic invertebrates to environmental changeThe relevance of laboratory experiments in predicting effects of climate change has been questioned, especially in Antarctica where sea temperatures are remarkably stable. Laboratory studies of Southern Ocean marine animal […]

The influence of diet on foraging habitat models: a case study using nursing fur seals
Read more of: The influence of diet on foraging habitat models: a case study using nursing fur sealsPredictable sources of food underpin lifetime reproductive output in long lived animals. The most important foraging areas of top marine predators are therefore likely to be related to environmental features […]

Temperature, metabolic power and the evolution of endothermy
Read more of: Temperature, metabolic power and the evolution of endothermyEndothermy has evolved at least twice, in the precursors to modern mammals and birds. The most widely accepted explanation for the evolution of endothermy has been selection for enhanced aerobic […]

Glacial geomorphology: towards a convergence of glaciology and geomorphology
Read more of: Glacial geomorphology: towards a convergence of glaciology and geomorphologyThis review presents a perspective on recent trends in glacial geomorphological research, which has seen an increasing engagement with investigating glaciation over larger and longer timescales facilitated by advances in […]

Poles apart: the “bipolar” pteropod species Limacina helicina is genetically distinct between the Arctic and Antarctic Oceans
Read more of: Poles apart: the “bipolar” pteropod species Limacina helicina is genetically distinct between the Arctic and Antarctic OceansThe shelled pteropod (sea butterfly) Limacina helicina is currently recognised as a species complex comprising two sub-species and at least five “forma”. However, at the species level it is considered […]

Millennial-scale variability during the last glacial: the ice core record
Read more of: Millennial-scale variability during the last glacial: the ice core recordThe oxygen-isotope records from Greenland ice cores show a very strong, reproducible pattern of alternation between warm Greenland Interstadials (GI) and cold Greenland Stadials (GS) at millennial-scale during the last […]
