The study of Antarctic communities can provide a valuable step forward in investigating the control of community development, the utilization of habitats and the interaction among species in both species rich and species poor communities. This book contains chapters characterizing the present approaches to both aquatic and terrestrial communities in the Antarctic. From biodiversity to trophic flows, from ecophysiological strategies to the impacts of environmental change and the effects of human disturbance, this volume provides an up to the minute overview of community studies in an area covering ten percent of the Earth's surface.

This book brings together many of the world’s leading experts in the fields of Antarctic terrestrial soil ecology, providing a comprehensive and completely up-to-date analysis of the status of Antarctic soil microbiology. Antarctic terrestrial soils represent one of the most extreme environments on Earth. Once thought to be largely sterile, it is now known that these diverse and often specialized extreme habitats harbor a very wide range of different microorganisms. Antarctic soil communities are relatively simple, but not unsophisticated. Recent phylogenetic and microscopic studies have demonstrated that these communities have well established trophic structuring and play a significant role in nutrient cycling in these cold and often dry desert ecosystems. They are surprisingly responsive to change and potentially sensitive to climatic perturbation. Antarctic terrestrial soils also harbor specialized ‘refuge’habitats, where microbial communities develop under (and within) translucent rocks. These cryptic habitats offer unique models for understanding the physical and biological ‘drivers’ of community development, function and evolution.

Bachelor Thesis from the year 2011 in the subject Biology - Geobiology, University of Hull (Centre for Environmental and Marine Sciences), course: Coastal Marine Biology, language: English, abstract: This study was carried out in the lab to identify species that were collected from three sites (Cape Smellie, Past Clark and Nunatak) on Byers peninsula, Livingston Island South Shetland Islands. The study was to investigate whether the length of time a site had been ice free affected community structure. It was found that Cape Smellie had the highest species richness with sixteen more species than Past Clark and twenty-nine more species than Nunatak. Cape Smellie also had the highest of species and was the site that had been ice free for the longest time period +50 years and the Nunatak samples showed a higher diversity than the other two site samples and is the site that has been ice free for less than 10 years. All of the sites sampled were found to have high numbers of Laevilltorina calignosa, Donacidae, Spinonid, Plathyhelminthe and Amphipods, all of which are highly adaptive species to different stress gradients and are all found worldwide in different types of ecosystems. The main findings in this study suggest that glacial retreat could be a possible cause for the increase in species as the data shows that glacial retreat over time co-insides with the increase in species abundant richness and diversity found on the different sites. There is a good possibility that there are different stages of colonisation by different species being seen in this study, and that location of the sites and the different stress gradients, substrata and exposure are possible controlling factors in the type of species and their found at the different sites. All three study sites had ten of the same species present; amphipods two, three, four, six, and nine, Terrebellida, Nephtyidae, Donacidae, Plathyhelminthe one and two and Enchytraeidae, but as likely, the substrata and different stress gradients i.e. wave intensity tolerance to freezing, the dominant species found on the study sites at Byers peninsula also correspond with the majority of studies carried out on other islands in and around the Antarctic region.

A structured account of the full range of environments in Antarctica and of the microbial communities that live within them. The author examines the major features of the chemical and physical environment in each habitat, and the influence of these features on the population structure and dynamics of their microbiota. Each chapter considers a specific type of environment, the microbial species that dominate, their community structure and dynamics, and the microbial processes that operate and have been measured in the ecosystem. The chapters conclude with an overview of the ecosystem trophic structure and an introduction to the larger organisms that depend on the microbiota. Separate chapters examine the range of cellular strategies adopted by microorganisms within the Antarctic environment, and the increasing influence of humans on these communities.

The book is based on results from the Russian expedition in the region of the Antarctic Peninsula and Powell Basin in the northern part of the Weddell Sea, as well as on the review of earlier research in the region. The main goal of the research was to collect the newest data and study the physical properties and ecology of this key region of the Southern Ocean. Data analysis is supplemented with numerical modeling of the atmosphere-ocean interaction and circulation in the adjacent region, including research on rogue waves. The focus of the study was the Antarctic Circumpolar Current, currents and water properties in the Bransfield Strait and Antarctic Sound, properties of seawater, currents, ecosystem and biological communities in the Powell Basin of the northwestern Weddell Sea, and their variations. An attempt is made to reveal the role of various components of the Antarctic environment in the formation of biological productivity and maintenance of the Antarctic krill population. This is especially important as in the last decades the Antarctic environment has experienced significant changes related to the global climatic trends.
