1. Arbuscular mycorrhizas are present on Spitsbergen

   A previous study of 76 plant species on Spitsbergen in the High Arctic concluded that structures resembling arbuscular mycorrhizas were absent from roots. Here, we report a survey examining the […]

2. Global biogeographic patterns in bipolar moss species

   A bipolar disjunction is an extreme, yet common, biogeographic pattern in non-vascular plants, yet its underlying mechanisms (vicariance or long-distance dispersal), origin and timing remain poorly understood. Here, combining a […]

3. Neogene to Quaternary stratigraphic evolution of the Antarctic Peninsula, Pacific Margin offshore of Adelaide Island: transitions from a non-glacial, through glacially-influenced to a fully glacial state

   A detailed morphologic and seismic stratigraphic analysis of the continental margin offshore of Adelaide Island on the Pacific Margin of the Antarctic Peninsula (PMAP) is described based on the study […]

4. Icechrono1: a probabilistic model to compute a common and optimized chronology for several ice cores

   Polar ice cores provide exceptional archives of past environmental conditions. The dating of ice cores and the estimation of the age-scale uncertainty are essential to interpret the climate and environmental […]

5. Recent advances on the dynamical representation and our understanding of the warmer-than-present last interglacial climate

   The Last Interglacial (LIG, ~129-116 thousand years Before Present, hereafter ka) represents an ideal case study to understand the climate mechanisms at play under a warmer-than-present climate. However a spatio-temporal […]

6. Does genetic structure reflect differences in non-breeding movements? A case study in small, highly mobile seabirds

   In seabirds, the extent of population genetic and phylogeographic structure varies extensively among species. Genetic structure is lacking in some species, but present in others despite the absence of obvious […]

7. Climate change drives expansion of Antarctic ice-free habitat

   Antarctic terrestrial biodiversity occurs almost exclusively in ice-free areas that cover less than 1% of the continent. Climate change will alter the extent and configuration of ice-free areas, yet the […]

11. Influence of changing temperature on growth rate and competition between two psychrotolerant Antarctic bacteria: competition and survival in non-steady-state temperature environments

    Competition between two psychrotolerant bacteria was examined in glycerol-limited chemostat experiments subjected to non-steady-state conditions of temperature. One bacterium, a Brevibacterium sp. strain designated CR3/1/15, responded rapidly to temperature change, […]

12. Improvements to the accuracy of zenith-sky measurements of total ozone by visible spectrometers

    Visible spectra of the zenith-sky were recorded at Faraday in Antartica (65°S) during 1990. Line-of-sight ozone amounts were deduced by fitting laboratory cross-sections to the spectra. At the lattitude of […]
