Chaenocephalus aceratus (Family Channicthyidae) is one of the dominant species of demersal fish living on the South Georgia shelf where it is caught in low numbers as by-catch in the […]
The 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 […]
Approaches 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 […]
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), […]
The 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 […]
Antarctic 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 […]
1. 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 […]
We 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 […]

A 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 […]
Deception 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 […]
