A new species of Pareledone (Cephalopoda: Octopodidae) from Antarctic Peninsula Waters
Read more of: A new species of Pareledone (Cephalopoda: Octopodidae) from Antarctic Peninsula WatersDuring recent cruises aboard RV Polarstern in the Antarctic Peninsula region, a new species of benthic octopodid was discovered whose generic affinities based on morphological characteristics were uncertain. Molecular sequence […]

Acceleration mechanism responsible for the formation of the new radiation belt during the 2003 Halloween solar storm
Read more of: Acceleration mechanism responsible for the formation of the new radiation belt during the 2003 Halloween solar stormObservations of the relativistic electron flux increases during the first days of November, 2003 are compared to model simulations of two leading mechanisms for electron acceleration. It is demonstrated that […]

Review on the distribution and biology of Antarctic Monoplacophora, with first abyssal record of Laevipilina antarctica
Read more of: Review on the distribution and biology of Antarctic Monoplacophora, with first abyssal record of Laevipilina antarcticaRecords of extant Monoplacophora are still scarce, often limited to single specimens or empty shells. Little is known about monoplacophoran diversity, distribution and biology. This study summarizes the present distributional […]

Protozoans as a food source for Antarctic krill, Euphausia superba: complementary insights from stomach content, fatty acids, and stable isotopes
Read more of: Protozoans as a food source for Antarctic krill, Euphausia superba: complementary insights from stomach content, fatty acids, and stable isotopesWe studied the diet of Antarctic krill, Euphausia superba, at five stations across the southwest Atlantic sector in summer 2003 by analyzing stomach content, fatty acids, and stable isotopes on […]

Modelling in molecular biology: describing transcription regulatory networks at different scales
Read more of: Modelling in molecular biology: describing transcription regulatory networks at different scalesApproaches to describe gene regulation networks can be categorized by increasing detail, as network parts lists, network topology models, network control logic models or dynamic models. We discuss the current […]

A reassessment of the distribution of the common Antarctic scallop Adamussium colbecki (Smith, 1902)
Read more of: A reassessment of the distribution of the common Antarctic scallop Adamussium colbecki (Smith, 1902)The bivalve Adamussium colbecki is an endemic Antarctic pectinid that can be locally abundant in nearshore habitats, sometimes as the dominant species. However, its distribution around the Antarctic continent is […]

Towards improved empirical isobase models of Holocene land uplift for mainland Scotland, UK
Read more of: Towards improved empirical isobase models of Holocene land uplift for mainland Scotland, UKA new approach to modelling patterns of glacio-isostatic land uplift during the Holocene in mainland Scotland, UK, is described. The approach is based upon altitude measurements at the inner margin […]

Glacial/interglacial changes in mineral dust and sea-salt records in polar ice cores: sources, transport, and deposition
Read more of: Glacial/interglacial changes in mineral dust and sea-salt records in polar ice cores: sources, transport, and depositionSea salt and mineral dust records as represented by Na+ and Ca2+ concentrations, respectively, in Greenland and Antarctic ice cores show pronounced glacial/interglacial variations. For the Last Glacial Maximum (LGM) […]

The Cape Purvis volcano, Dundee Island (northern Antarctic Peninsula): late Pleistocene age, eruptive processes and implications for a glacial palaeoenvironment
Read more of: The Cape Purvis volcano, Dundee Island (northern Antarctic Peninsula): late Pleistocene age, eruptive processes and implications for a glacial palaeoenvironmentCape Purvis is a conspicuous promontory on southern Dundee Island. It forms a prominent mesa that contrasts with the smooth, shield-like (snow-covered) topography of the remainder of the island. The […]
