Risks posed to the Antarctic marine environment by acoustic instruments: a structured analysis
Read more of: Risks posed to the Antarctic marine environment by acoustic instruments: a structured analysisThe risks posed by a range of acoustic scientific instruments were assessed by the construction of matrices of scale and likelihood. We recognized six levels of impact ranging from none […]

Modelling gene networks at different organisational levels
Read more of: Modelling gene networks at different organisational levelsApproaches to modelling gene regulation networks can be categorized, according to increasing detail, as network parts lists, network topology models, network control logic models, or dynamic models. We discuss the […]

Which cyanobacterial genotypes are observed in microbial mats of Antarctic lakes?
Read more of: Which cyanobacterial genotypes are observed in microbial mats of Antarctic lakes?Cyanobacteria are the dominant phototrophs in Antarctic biota where they form conspicuous microbial mats at the bottom of lakes and ponds. In the frame of the OSTC project LAQUAN (EV/12/1B), […]

Thermal analysis of the plant encapsulation-dehydration cryopreservation protocol using silica gel as the desiccant
Read more of: Thermal analysis of the plant encapsulation-dehydration cryopreservation protocol using silica gel as the desiccantThe encapsulation-dehydration cryopreservation protocol is critically dependent upon the evaporative desiccation step, which must optimise survival with the retention of glass stability on sample cooling and rewarming. Desiccation is usually […]

Relative production of Calanoides acutus (Copepoda: Calanoida) and Euphausia superba (Antarctic krill) at South Georgia, and its implications at wider scales
Read more of: Relative production of Calanoides acutus (Copepoda: Calanoida) and Euphausia superba (Antarctic krill) at South Georgia, and its implications at wider scalesAntarctic krill are often described as the major species in Southern Ocean food webs, but there have been no direct site-specific comparisons between their production and that of copepods that […]

Habitat-specific normal and reverse diel vertical migration in the plankton-feeding basking shark
Read more of: Habitat-specific normal and reverse diel vertical migration in the plankton-feeding basking shark1. Megaplanktivores such as filter-feeding sharks and baleen whales are at the apex of a short food chain (phytoplankton–zooplankton–vertebrate) and are sensitive indicators of sea-surface plankton availability. Even though they […]

Observations of stratospheric warmings and mesospheric coolings by the TIMED SABER instrument
Read more of: Observations of stratospheric warmings and mesospheric coolings by the TIMED SABER instrumentWe used temperature data from the Sounding of the Atmosphere with Broadband Emission Radiometry (SABER) on the the NASA TIMED satellite to quantify the connection between temperatures in the stratosphere […]

Bryophyte diversity and ecology of two geologically contrasting Antarctic islands
Read more of: Bryophyte diversity and ecology of two geologically contrasting Antarctic islandsA comparison is made of the bryophyte floras of two small maritime Antarctic islands lying at similar latitudes and with similar climates and glacial topographies, but differing markedly in their […]

The bryophyte flora of geothermal habitats on Deception Island, Antarctica
Read more of: The bryophyte flora of geothermal habitats on Deception Island, AntarcticaDeception Island is one of the most volcanically active sites south of 60°S. Between 1967 and 1970 three major eruptions devastated large expanses of the landscape and its predominantly cryptogamic […]

Extensive colonization of volcanic ash by an unusual form of Peltigera didactyla at Deception Island, maritime Antarctic
Read more of: Extensive colonization of volcanic ash by an unusual form of Peltigera didactyla at Deception Island, maritime AntarcticPeltigera didactyla (With.) J. R. Laundon has a cosmopolitan distribution, but in the Antarctic it is very restricted and is nowhere common or abundant, occurring at a number of sites […]
