Soil fungal community composition does not alter along a latitudinal gradient through the maritime and sub-Antarctic
Read more of: Soil fungal community composition does not alter along a latitudinal gradient through the maritime and sub-AntarcticWe investigated the relationships between fungal community composition, latitude and a range of physicochemical parameters in 58 soils sampled from a 2370 km latitudinal gradient between South Georgia (54°S, 38°W) […]

The influence of eddy parameterizations on the transport of the Antarctic Circumpolar Current in coupled climate models
Read more of: The influence of eddy parameterizations on the transport of the Antarctic Circumpolar Current in coupled climate modelsThe transport of the AntarcticCircumpolarCurrent (ACC) varies strongly across the coupled GCMs (general circulation models) used for the IPCC AR4. This note shows that a large fraction of this across-model […]

Comparing Bongo net and N70 mesozooplankton catches: using a reconstruction of an original net to quantify historical plankton catch data
Read more of: Comparing Bongo net and N70 mesozooplankton catches: using a reconstruction of an original net to quantify historical plankton catch dataIf Southern Ocean plankton communities are changing in response to climate, biases in various nets need to be evaluated to help understand regional and temporal differences between historical and contemporary […]

Influence of allochtonous nutrients delivered by colonial seabirds on soil collembolan communities on Spitsbergen
Read more of: Influence of allochtonous nutrients delivered by colonial seabirds on soil collembolan communities on SpitsbergenDespite a widespread recognition of the role of seabird colonies in the fertilization of nutrient-poor polar terrestrial ecosystems, qualitative and quantitative data documenting any consequential influence on soil invertebrate communities […]

Nonlinear trends, long-range dependence and climate noise properties of surface temperature
Read more of: Nonlinear trends, long-range dependence and climate noise properties of surface temperatureThis study investigates the significance of trends of four temperature time series—Central England Temperature (CET), Stockholm, Faraday-Vernadsky, and Alert. First the robustness and accuracy of various trend detection methods are […]

Primary succession of lichen and bryophyte communities following glacial recession on Signy Island, South Orkney Islands, Maritime Antarctic
Read more of: Primary succession of lichen and bryophyte communities following glacial recession on Signy Island, South Orkney Islands, Maritime AntarcticA directional primary succession with moderate species replacement was quantitatively characterized on Signy Island in zones of a glacial valley corresponding to their age since deglaciation. A continuous increase in […]

Diversity and distribution patterns in high southern latitude sponges
Read more of: Diversity and distribution patterns in high southern latitude spongesSponges play a key role in Antarctic marine benthic community structure and dynamics and are often a dominant component of many Southern Ocean benthic communities. Understanding the drivers of sponge […]

Glacial geomorphology and cosmogenic 10Be and 26Al exposure ages in the northern Dufek Massif, Weddell Sea embayment, Antarctica
Read more of: Glacial geomorphology and cosmogenic 10Be and 26Al exposure ages in the northern Dufek Massif, Weddell Sea embayment, AntarcticaWe studied the glacial geomorphology and geochronology of two ice-free valleys in the Dufek Massif (Antarctic Specially Protected Area 119) providing new constraints on past ice sheet thickness in the […]

Fatty acid trophic markers elucidate resource partitioning within the demersal fish community of South Georgia and Shag Rocks (Southern Ocean)
Read more of: Fatty acid trophic markers elucidate resource partitioning within the demersal fish community of South Georgia and Shag Rocks (Southern Ocean)Fatty acid analysis was used to study the trophic ecology of 10 demersal fish species in the South Georgia region. Principal component analysis grouped the species into three general clusters, […]

Marine invertebrate skeleton size varies with latitude, temperature and carbonate saturation: implications for global change and ocean acidification
Read more of: Marine invertebrate skeleton size varies with latitude, temperature and carbonate saturation: implications for global change and ocean acidificationThere is great concern over the future effects of ocean acidification on marine organisms, especially for skeletal calcification, yet little is known of natural variation in skeleton size and composition […]
