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.

Antarctic Microbiology The extreme climate of Antarctica — its sub-zero temperatures, low humidity, high winds, and extended light and dark periods — has limited scientists in their search for information on microbial communities there and in the surrounding oceans. Most early microbiological research was descriptive and focused on the interactions of microbial communities with physical and chemical parameters. Today, thanks to enormous improvements in technology and logistics, microbiologists can study the functional processes of microbial communities and their biological interactions. Microbiological research in Antarctica is particularly relevant in light of today’s discussions on global climate change. This volume offers an account of the microbial habitats and communities that play significant roles in the ecosystem of the Antarctic continent. Antarctic Microbiology demonstrates the explosion of new and exciting research into microbial communities, physiological rate processes, and adaptation of species at the biochemical and molecular level. This text presents new information on: sea-ice microbial processes associated with the pack ice and the ocean photosynthesis, physiology, and adaptation of cryptoendolithic communities in sandstone formations biogeochemical cycling of carbon and nitrogen in unique lake systems in the dry valleys the development of microbial communities in volcanically heated soils the possible existence of ancient microbes in glacial ice biogeochemical cycling of elements in the marine ecosystem around Antarctica. Written by an international group of experts, Antarctic Microbiology will be of interest to all microbiologists and ecologists who study the diversity of microorganisms and their marine, freshwater, and terrestrial environments.

This book provides up-to-date multidisciplinary information regarding microbial physiological groups in terms of their role in the Antarctic ecology. How do microorganisms shape the Antarctic environment? The book presents a thorough overview of the most important physiological microbial groups or microbial systems that shape the Antarctic environment. Each microbial model is described in terms of their physiology and metabolism, and their role in the Antarctic environmental sustainability. The individual chapters prepare readers for understanding the relevance of the microbial models from both an historical perspective, and considering the latest developments. This book will appeal to researchers and teachers interested in the Antarctic science, but also to students who want to understand the role of microbes in the ecology of extreme environments.

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 McMurdo Dry Valleys form the largest relatively ice-free area on the Antarctic continent. The perennially ice-covered lakes, ephemeral streams and extensive areas of exposed soil are subject to low temperatures, limited precipitation and salt accumulation. The dry valleys thus represent a region where life approaches its environmental limits. This unique ecosystem has been studied for several decades as an analog to environments on other planets, particularly Mars. For the first time, the detailed terrestrial research of the dry valleys is brought together here, presented from an astrobiological perspective. Chapters include a discussion on the history of research in the valleys, a geological background of the valleys, setting them up as analogs for Mars, followed by chapters on the various sub-environments in the valleys such as lakes, glaciers and soils. Includes concluding chapters on biodiversity and other analog environments on Earth.

The Antarctic provides a suite of scenarios useful for investigating the range of climate change effects on terrestrial and limnetic biota. The purpose of the book is to provide, based on the most up to date knowledge, a synthesis of the likely effects of climate change on Antarctic terrestrial and limnetic ecosystems and, thereby, to contribute to their management and conservation, based on the information.
