Antarctic clouds
Sensitivity studies with global climate models show that, by their influence on the radiation balance, Antarctic clouds play a major role in the climate system, both directly at high southern […]

The ECMWF model climate: Recent progress through improved physical parametrizations
Read more of: The ECMWF model climate: Recent progress through improved physical parametrizationsThe progress achieved since 2005 in simulating today’s climate with the European Centre for Medium-Range Weather Forecasts (ECMWF) model through improved physical parametrizations is described. Results are based on climate […]

Getting long in the tooth: a strong positive correlation between canine size and heterozygosity in Antarctic fur seals Arctocephalus gazella
Read more of: Getting long in the tooth: a strong positive correlation between canine size and heterozygosity in Antarctic fur seals Arctocephalus gazellaMost studies of heterozygosity-fitness correlations (HFCs) in natural populations relate to fitness traits expressed early in life, whereas traits that are often more difficult to measure such as longevity and […]

Source, timing, frequency and flux of ice-rafted detritus to the Northeast Atlantic margin, 30-12 ka: testing the Heinrich precursor hypothesis
Read more of: Source, timing, frequency and flux of ice-rafted detritus to the Northeast Atlantic margin, 30-12 ka: testing the Heinrich precursor hypothesisIncreased fluxes of ice-rafted detritus (IRD) from European ice sheets have been documented some 1000-1500 years before the arrival of Laurentide Ice Sheet (LIS)-sourced IRD during Heinrich (H) events. These […]

Wind-driven diversion of summer river runoff preconditions the Laptev Sea coastal polynya hydrography: Evidence from summer-to-winter hydrographic records of 2007-2009
Read more of: Wind-driven diversion of summer river runoff preconditions the Laptev Sea coastal polynya hydrography: Evidence from summer-to-winter hydrographic records of 2007-2009This paper examines the role of atmospheric forcing in modifying the pathways of riverine water on the Laptev Sea shelf, using summer-to-winter hydrographic surveys from 2007-2009. Over the two consecutive […]

A carryover effect of migration underlies individual variation in reproductive readiness and extreme egg size dimorphism in Macaroni Penguins
Read more of: A carryover effect of migration underlies individual variation in reproductive readiness and extreme egg size dimorphism in Macaroni PenguinsWhere life-history stages overlap, there is the potential for physiological conflicts that might be important in mediating carryover effects. However, our knowledge of the specific physiological mechanisms underlying carryover effects […]

Growth and spread of the woodchip associated fungus Leratiomyces ceres in undisturbed garden soils
Read more of: Growth and spread of the woodchip associated fungus Leratiomyces ceres in undisturbed garden soilsA survey was undertaken to determine the extent of Leratiomyces ceres (syn. Stropharia aurantiaca sensu auct.) in soil surrounding apparently isolated occurrences of fungal fruit bodies on woodchip mulch. A […]

Responding to climate change: Adélie penguins confront astronomical and ocean boundaries
Read more of: Responding to climate change: Adélie penguins confront astronomical and ocean boundariesLong-distance migration enables many organisms to take advantage of lucrative breeding and feeding opportunities during summer at high latitudes and then to move to lower, more temperate latitudes for the […]
