Mesopelagic fish are a key component of the pelagic ecosystem throughout the world’s oceans. Opening and closing nets were used to investigate patterns in the distribution and abundance of mesopelagic […]
Multifrequency acoustic backscatter data were examined from transects at eight stations across the Scotia Sea, from the South Orkneys to the north west of South Georgia. These transects were repeated […]
In 2000 the UK started a Patagonian toothfish (Dissostichus eleginoides) tagging program to investigate the spatial and temporal movement of fish and to validate otolith-based growth estimates. Approximately 2 260 […]
Lecophagus antarcticus, described as a new species of predaceous Hyphomycete of rotifers and tardigrades, was collected from cyanobacterial mats and sediments at shallow lake margins on Signy Island, South Orkney […]
Photosynthetic activity of the moss Sanionia uncinata (Hedw.) Loeske was investigated on Léonie Island (67°35’S, 68°20’W, Antarctic Peninsula) in response to short-term changes of UV-B radiation. The UV-environment of natural […]
The spawning success of Antarctic krill (Euphausia superba) is generally assumed to depend on substantial winter sea ice extent, as ice biota can serve as a food source during winter/spring […]
Paleolimnology provides information on the past chemical, physical and biological nature of water bodies. In polar regions, where global climatic changes can be exacerbated compared with lower latitudes, the science […]
Ultraviolet radiation (UVR) damages most biota, yet little evidence exists for its long-term effects on natural ecosystems. We used paleoecological techniques at three low-elevation lakes to show that algal abundance […]
