Areas of barren rock and scree around the edge of Antarctica provide a breeding ground for two of the continent's most well-known species of bird: the south polar skua and the Adélie penguin. This book considers the relationship between these two species, taking as its study site Ross Island. Through detailed observations of the foraging ecology of the skua, the traditional view that skuas are totally dependent on penguin eggs and chicks for food is challenged. In addition, studies of the impact of skuas on penguin breeding and the extent to which the skua breeding cycle is functionally related to that of the penguin provide further evidence to suggest that the two species occur together independently as a consequence of limited breeding space, rather than as a result of a distinct predator-prey relationship.

Ice exists in water, in air, in earth and in living organisms. The purpose of this book is to describe in mathematical, physical and biological terms, the growth and decay of ice, on a scale ranging from molecular to macroscopic. Consideration of the growth of ice in each of the above contexts provides a clearer understanding of the processes involved and results in a comprehensive overview not available elsewhere. This book will be of particular use to any graduate student, scientist or engineer requiring an introduction and reference for ice-related projects: theoretical or experimental; in the laboratory or the field.

This wide-ranging account of the life of the tundra provides a fascinating insight into the ways in which animals, plants and climate interact in an inhospitable environment. Although the tundra is not rich in species compared with habitats in the tropics or even in temperate regions, it is an area of great interest to ecologists, botanists and zoologists alike, as an excellent example of nature contending with extreme environmental stress. As a biogeographer and ecologist the author has used his firsthand experience of the Eurasian Sub-Arctic to present an overview of life on the tundra of the Soviet Northlands that has become a classic of ecological literature. The tradition of interdisciplinary studies is very strong among Soviet tundra scientists. This important book is a valuable guide to the life of the tundra and will interest all those interested in the conservation of its flora and fauna.

This book provides a structured account of the full range of environments in Antarctica and of the microbial communities that live within them. Environments examined include: snow and ice; benthic marine; sea ice; lakes and streams; marginal ice; soil; the open ocean; rock. In the more extreme habitats of this region microscopic life forms constitute the entire biology of the habitat, but in all antarctic environments the microbial communities play a major and often dominant role in the transfer of carbon, nutrients and energy throughout the ecosystem. The book 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.
