Observations of an enhanced convection channel in the cusp ionosphere
Read more of: Observations of an enhanced convection channel in the cusp ionosphereTransient or patchy magnetic field line merging on the dayside magnetopause, giving rise to flux transfer events (FTEs), is thought to play a significant role in energizing high-latitude ionospheric convection […]

Pedal mucus production by the Antarctic limpet Nacella concinna (Strebel, 1908)
Read more of: Pedal mucus production by the Antarctic limpet Nacella concinna (Strebel, 1908)Pedal mucus production rates were measured in the Antarctic limpet Nacella concinna (Strebel, 1908). Measurements were taken over 30-min and 24-h periods to allow the relative amounts of mucus produced […]

Larval development in the Antarctic nemertean Parborlasia corrugatus (Heteronemertea: Lineidae)
Read more of: Larval development in the Antarctic nemertean Parborlasia corrugatus (Heteronemertea: Lineidae)Embryonic and larval development were followed from fertilisation to settlement in the Antarctic heteronemertean Parborlasia corrugatus (McIntosh, 1876). The first cleavage occurred 10 to 15 h after fertilisation, and the […]

The tissues of articulate brachiopods and their value to predators
Read more of: The tissues of articulate brachiopods and their value to predatorsThe punctate brachiopods Liothyrella neozelanica and Neothyris lenticularis were compared with the impunctate Notosaria nigricans and the bivalve molluscs Mytilus edulis and Lima colorata in terms of the force needed […]

CMIP5 diversity in southern westerly jet projections related to historical sea ice area; strong link to strengthening and weak link to shift
Read more of: CMIP5 diversity in southern westerly jet projections related to historical sea ice area; strong link to strengthening and weak link to shiftA major feature of projected changes in Southern Hemisphere climate under future scenarios of increased greenhouse gas concentrations is the poleward shift and strengthening of the main eddy-driven belt of […]

Dwarf shrub and grass vegetation resistant to long-term experimental warming while microarthropod abundance declines on the Falkland Islands
Read more of: Dwarf shrub and grass vegetation resistant to long-term experimental warming while microarthropod abundance declines on the Falkland IslandsDwarf shrubs are a dominant plant type across many regions of the Earth and have hence a large impact on carbon and nutrient cycling rates. Climate change impacts on dwarf […]

Cross-disciplinarity in the advance of Antarctic ecosystem research
Read more of: Cross-disciplinarity in the advance of Antarctic ecosystem researchThe biodiversity, ecosystem services and climate variability of the Antarctic continent and the Southern Ocean are major components of the whole Earth system. Antarctic ecosystems are driven more strongly by […]
