Temperature observations between 20 and 120 km from the SABER instrument on the TIMED spacecraft are used to investigate the nature of planetary wave activity during the 60 days prior […]
Scophthalmus maximus is an important commercially aquaculture fish species. We tackle the search for new microsatellites using two different approaches: an enriched partial genomic library and a screening of all […]
The comparatively low latitude of the Tasman International Geospace Environment Radar (TIGER) (147.2°E, 43.4°S, geographic; −54.6°Λ), a Southern Hemisphere HF SuperDARN radar, facilitates the observation of extensive backscatter from decametre-scale […]
Earthward injections of energetic ions and electrons mark the onset of magnetospheric substorms. In the inner magnetosphere (L~4), the energetic ions drift westward and the electrons eastward, thereby enhancing the […]
The MODVOLC satellite monitoring system has revealed the first recorded eruption of Mount Belinda volcano, on Montagu Island in the remote South Sandwich Islands. Here we present some initial qualitative […]
In this study, variation in the bacterioplankton community structure of three Antarctic lakes of different nutrient status, was determined in relation to physical and chemical gradients at depth and at […]
Nutrient enrichment is known to increase bacterioplankton population density in a variety of Antarctic freshwater lakes. However, relatively little is known about the associated changes in species composition. In this […]
Organisms have a limited number of responses that enhance survival in changing environments. They can: 1. Cope within existing physiological flexibility; 2. Adapt to changing conditions; or 3. Migrate to […]
Maritime Antarctic freshwater habitats are amongst the fastest changing environments on Earth. Temperatures have risen around 1°C and ice cover has dramatically decreased in 15 years. Few animal species inhabit […]
The size of an organism is of fundamental importance in all biological processes. It dictates many of the critical interactions and physical factors that delimit the envelope within which an […]
The ice gouged, shallow, polar seabed is a challenging place to live, but suspension feeders are particularly rich and abundant there. The extreme seasonality of food supply from phytoplankton at […]
Biological research in Antarctica has made considerable progress in science over recent decades. As little as 50 years ago, there was scant knowledge even of the species inhabiting the region. […]
