Outside Russia very little is known about the terrestrial ecology, vegetation, biogeographical patterns, and biodiversity of the enormously extensive ecosystems of Yakutia, Siberia. These systems are very special in that they function on top of huge layers of permafrost and are exposed to very severe and extreme weather conditions, the range between winter and summer temperatures being more than 100 degrees C. The soils are generally poor, and human use of the vegetation is usually extensive. Main vegetation zones are taiga and tundra, but Yakutia also supports a special land and vegetation form, caused by permafrost, the alas: more or less extensive grasslands around roundish lakes in taiga. All these vegetation types will be described and their ecology and ecophysiological characteristics will be dealt with. Because of the size of Yakutia, covering several climatic zones, and its extreme position on ecological gradients, Yakutia contains very interesting biogeographical patterns, which also will be described. Our analyses are drawn from many years of research in Yakutia and from a vast body of ecological and other literature in Russian publications and in unpublished local reports. The anthropogenic influence on the ecosystems will be dealt with. This includes the main activities of human interference with nature: forestry, extensive reindeer herding, cattle and horse grazing, etc. Also fire and other prominent ecological factors are dealt with. A very important point is also the very high degree of naturalness that is still extant in Yakutia’s main vegetation zones.

Loess is a product of aeolian deposition during the Quaternary glaciation cycles and covers approximately 6% of the Earth’s land. The Loess Plateau of China, which is home to a population of nearly three hundred million, has the thickest and most complete loess strata, where loess geohazards occur most frequently due to the weak geoenvironment and dense human activities. In recent years, the engineering geological characteristics of loess and geohazards in loess areas have gradually received increasing attention from academic researchers. This book reviews an informative collection of up-to-date literature in this field. It presents the unique features of loess and loess geohazards, and provides a strong foundation for future study via eight systematically structured chapters, e.g., origin and spatial distribution, loess landforms, microstructure, physical properties, permeability, shear strength, tensile strength, and loess geohazard. It can serve as a principal reference for researchers, practical engineers and technicians who are engaged in loess geology and surface processes, and is suitable especially for undergraduate and postgraduate students in the field of loess engineering geology.

Cryosols – permafrost – occupy a unique part of the earth and have properties greatly different from other soils. They also occur where the greatest impact of global warming is predicted. This is the first book bring together the leading researchers in the area of permafrost soils to produce a review of the geography, cryogenic soil forming processes, ecological processes, classification and use of soils that are affected by permafrost.

Paleoecology of Beringia is the product of a symposium organized by its editors, sponsored by the Wenner-Gren Foundation for Anthropological Research, and held at the foundation's conference center in Burg Wartenstein, Austria, 8-17 June 1979. The focus of this volume is on the paradox central to all studies of the unglaciated Arctic during the last Ice Age: that vertebrate fossils indicate that from 45,000 to 11,000 years BP an environment considerably more diverse and productive than the present one existed, whereas the botanical record, where it is not silent, supports a far more conservative appraisal of the region's ability to sustain any but the sparsest forms of plant and animal life. The volume is organized into seven parts. Part 1 focuses on the paleogeography of the Beringia. The studies in Part 2 explore the ancient vegatation. Part 3 deals with the steppe-tundra concept and its application in Beringia. Part 4 examines the paleoclimate while Part 5 is devoted to the biology of surviving relatives of the Pleistocene ungulates. Part 6 takes up the presence of man in ancient Beringia. Part 7 assesses the paleoecology of Beringia during the last 40,000 years

This book discusses the water and carbon cycle system in the permafrost region of eastern Siberia, Providing vitalin sights into how climate change has affected the permafrost environment in recent decades. It analyzes the relationships between precipitation and evapotranspiration, gross primary production and runoff in the permafrost regions, which differ from those intropical and temperate forests. Eastern Siberia is located in the easternmost part of the Eurasian continent, and the land surface with underlying permafrost has developed over a period of seventy thousand years. The permafrost ecosystem has specific hydrological and meteorological characteristics in terms of the water and carbon dynamics, and the current global warming and resulting changes in the permafrost environment are serious issues in the high-latitude regions. The book is a valuable resource for students, researchers and professionals interested in forest meteorology and hydrology, forest ecology, and boreal vegetation, as well as the impact of climate change and water-carbon cycles in permafrost and non-permafrost regions.

The theme of this proceedings volume is the latest research on geomorphic characteristics and processes associated with natural hazards. Presentations cover a gamut of types of disasters throughout the world, describing research and applications of studies in the U.S. and other countries. The book begins with a collection of papers giving a basic background and philosophy of approaching an understanding of natural disasters. These are followed by papers on natural hazards in coastal areas, mountainous regions, landslides, flooding and the detrimental effects of permafrost. The book should prove valuable in gaining an insight of natural hazards and their geomorphic relations, which is imperative for prudent environmental planning in coping with disasters.
