Global fungal diversity is estimated to range in the millions, yet it remains severely underexplored, especially in extreme environments. Fewer than 5% of species have been officially identified and characterised. Estimates suggest that 70%–90% of soil fungi remain uncultivable…

The composition of the stratosphere is driven by transport, temperatures and processes in the tropical tropopause layer – this has implications for ozone, radiation, and surface climate. The properties of the tropical tropopause layer have changed in recent decades, e.g.
The ozone loss simulated with climate models is based on laboratory kinetic data. These laboratory data are difficult to conduct at stratospheric pressures and temperatures and there is substantial uncertainty surrounding these parameters.
We review the scientific literature, especially from the past decade, on the impacts of human … activities on the Antarctic environment. A range of impacts has been identified at a variety of spatial and … temporal scales.
The recent distributional history of two Macquarie … Island vascular plant species, Carex trifida, Poa … litorosa, and the Heard Island vascular plant, Ranunculus … crassipes is examined. C. trifida is known from only … one small population on the north west coast of Macquarie … Island.

From a synthesis of recent oceanic observations and paleo-data it is evident that certain species … of giant diatoms including Rhizosolenia spp. Thalassiothrix spp. and Ethmodiscus rex may … become concentrated at oceanic frontal zones and subsequently form episodes of mass flux to the … sediment.

We present colour-colour and colour-magnitude diagrams for RCW 57 (NGC … 3576) based on L-band data at 3.5 ìm taken with SPIREX (South Pole Infrared Explorer), and 2MASS JHKs data at 1.25-2.2 ìm. A total of 251 sources were detected.
L-band data of 30 Doradus at 3.5 ìm taken with SPIREX (South Pole Infrared Explorer) is presented. The photometry … was combined with 2MASS JHK data at 1.25 -2.2 ìm. Colour-colour and colour-magnitude diagrams are constructed and used to determine the sources with infrared excess.
Harvesting of marine living resources in the Southern Ocean is managed by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), which is widely known for its ecosystem approach to managing fisheries and inclusion of food-web maintenance in the conservation objectives.
In order to improve our understanding of wintertime polar ozone losses, two ozonesonde Match campaigns were performed. The first one was carried out in the Arctic winter 2002/03. About 450 co-ordinated ozonesondes were launched from late November 2002 to March 2003.
To measure chemical induced ozone loss in the Arctic lower stratosphere the Match method was developed. Trajectory calculations based on stratospheric wind fields of the European Center of Medium-range Weather Forecasts (ECMWF) are used to track and to predict the ways of air parcels.
In order to improve our understanding of the January losses of ozone in the Arctic vortex two ozonesondes Match campaigns are scheduled within the project "Quantitative Understanding of Ozone losses by Bipolar Investigations" (QUOBI).
