1. Antarctic geoconservation: a review of current systems and practices

   The prohibition of commercial mineral resource extraction through the Antarctic Treaty System has removed one significant source of potential damage to Antarctica’s geological and geomorphological values. However, given the on-going […]

3. Moss stable isotopes (carbon-13, oxygen-18) and testate amoebae reflect environmental inputs and microclimate along a latitudinal gradient on the Antarctic Peninsula

   The stable isotope compositions of moss tissue water (δ2H and δ18O) and cellulose (δ13C and δ18O), and testate amoebae populations were sampled from 61 contemporary surface samples along a 600-km […]

4. Lichen photobiont diversity and selectivity at the southern limit of the maritime Antarctic region (Coal Nunatak, Alexander Island)

   Antarctic ice-free inland sites provide a unique perspective on the strategies coevolving organisms have developed for survival at the limits of life. Here, we provide the first combined description of […]

5. Subglacial processes on an Antarctic ice stream bed 1: sediment transport and bedform genesis inferred from marine geophysics

   The spatial pattern and morphometry of bedforms and their relationship to sediment thickness have been analysed in the Marguerite Bay Palaeo-ice stream Trough, western Antarctic Peninsula. Over 17 000 glacial […]

6. Subglacial processes on an Antarctic ice stream bed 2: Can modelled ice dynamics explain the morphology of mega-scale glacial lineations?

   Mega-scale glacial lineations (MSGLs) are highly elongate subglacial bedforms associated with ice streaming. However, the link between MSGLs and rapid ice flow is largely qualitative, and there have been few […]

7. Composition and interactions among bacterial, microeukaryotic, and T4-like viral assemblages in lakes from both polar zones

   In this study we assess global biogeography and correlation patterns among three components of microbial life: bacteria, microeukaryotes, and T4-like myoviruses. In addition to environmental and biogeographical considerations, we have […]

8. An automated methodology for differentiating rock from snow, clouds and sea in Antarctica from Landsat 8 imagery: A new rock outcrop map and area estimation for the entire Antarctic continent

   As the accuracy and sensitivity of remote-sensing satellites improve, there is an increasing demand for more accurate and updated base datasets for surveying and monitoring. However, differentiating rock outcrop from […]

9. Antarctic Entomology

   The Antarctic region comprises the continent, the Maritime Antarctic, the sub-Antarctic islands, and the southern cold temperate islands. Continental Antarctica is devoid of insects, but elsewhere diversity varies from 2 […]

11. Antarctic palynology and palaeoclimate – a review

    The first exciting clues that Antarctica had not always been ice-covered were the leaf fossils of Glossopteris plants that Scott’s party brought back from the Beardmore Glacier region in 1912. […]

12. Not poles apart: Antarctic soil fungal communities show similarities to those of the distant Arctic

    Antarctica’s extreme environment and geographical isolation offers a useful platform for testing the relative roles of environmental selection and dispersal barriers influencing fungal communities. The former process should lead to […]
