Open Top Chambers are passive warming systems used to experimentally assess the effect of climate change on terrestrial ecosystems, and they were used in several Antarctic regions to study the response of biotic communities. In the BELSPO BELDIVA project, OTCs were used in continental Eastern Antarctica, where environmental conditions are very extreme. In January 2010, 8 Open-Top Chambers (OTC) were installed in four ice-free regions of the Sör Rondane Mountains, namely on the Utsteinen ridge, the Tanngarden granite outcrop, the Teltet nunatak and the fourth nunatak of the Pingvinane range.

In continental Antarctica, the environnmental conditions are extreme and only microbial organisms can withstand them. Currently, the majority of OTCs experiments are being held in Maritime Antarctica but it would be interesting to have such data for the continental part of Eastern Antarctica. To monitor the response of the microbial communities to local simulations of climate change, 8 Open-Top Chambers (OTC) were installed close to the Princess Elisabeth station, in the Sor Rondane Mountains in January 2010. They are located on the Utsteinen ridge, the Tanngarden granite outcrop, the Teltet nunatak and the fourth nunatak of the Pingvinane range. In each location, two OTCs and a control area were established. Temperature and humidity loggers were installed inside the OTCs and outside, in the control areas, to estimate the environmental changes induced by the OTCs. [less ▲]

The network of ASPAs (Antarctic Specially Protected Areas) that is presently under construction in the frame of the Committee for Environmental Protection of the Antarctic Treaty is intended to protect "outstanding environmental, scientific, historic, aesthetic or wilderness values, any combination of those values, or ongoing or planned scientific research" (http://www.ats.aq/e/ep_protected.htm). When the Madrid Protocol was signed, twenty-one years ago, the knowledge on the biodiversity of tiny and microscopic organisms was much less extensive and molecular methods for biodiversity assessments were only in their infancy. The majority of the permanent inhabitants of Antarctica are, however, essentially microscopic. [less ▲]

The new Belgian “Princess Elisabeth” research station was built in 2009 and is located 200 km inland in the Western part of the Sør Rondane Mountains (Eastern Antarctica). The BELSPO projects ANTAR-IMPACT and BELDIVA aimed to evaluate the diversity and the distribution patterns of the microorganisms from different types of habitats in a radius of 50 km around the Belgian station. These data will serve to follow future anthropogenic and climatic impacts on these communities. Here, we focus on the diversity of cyanobacteria. [less ▲]

Cyanobacteria inhabit the Antarctic continent and have even been observed in the most southerly ice-free areas of Antarctica (86–878 S). The highest molecular diversity of cyanobacterial communities was found in the areas located between 708 S and 808 S. Further south and further north from this zone, the diversity abruptly decreased. Seventy-nine per cent (33 of 42 operational taxonomic units) of Antarctic terrestrial cyanobacteria have a cosmopolitan distribution. Analysis of the sampling efforts shows that only three regions (southern Victoria Land, the Sør Rondane Mountains and Alexander Island) have been particularly well studied, while other areas did not receive enough attention. Although cyanobacteria possess a capacity for long-range transport, regional populations in Antarctic ice-free areas seem to exist. The cyanobacterial communities of the three most intensively studied regions, separated from each other by a distance of 3000–3400 km, had a low degree of similarity with each other. Further development of microbial biogeography demands a standardized approach. For this purpose, as a minimal standard, we suggest using the sequence of cyanobacterial 16S rRNA gene between Escherichia coli positions 405–780. [less ▲]
