This edited volume, showcasing cutting-edge research, addresses two primary questions - what are the main drivers of change in high-mountains and what are the risks implied by these changes? From a physical perspective, it examines the complex interplay between climate and the high-mountain cryosphere, with further chapters covering tectonics, volcano-ice interactions, hydrology, slope stability, erosion, ecosystems, and glacier- and snow-related hazards. Societal dimensions, both global and local, of high-mountain cryospheric change are also explored. The book offers unique perspectives on high-mountain cultures, livelihoods, governance and natural resources management, focusing on how global change influences societies and how people respond to climate-induced cryospheric changes. An invaluable reference for researchers and professionals in cryospheric science, geomorphology, climatology, environmental studies and human geography, this volume will also be of interest to practitioners working in global change and risk, including NGOs and policy advisors.

Mountains, Climate and Biodiversity: A comprehensive and up-to-date synthesis for students and researchers Mountains are topographically complex formations that play a fundamental role in regional and continental-scale climates. They are also cradles to all major river systems and home to unique, and often highly biodiverse and threatened, ecosystems. But how do all these processes tie together to form the patterns of diversity we see today? Written by leading researchers in the fields of geology, biology, climate, and geography, this book explores the relationship between mountain building and climate change, and how these processes shape biodiversity through time and space. In the first two sections, you will learn about the processes, theory, and methods connecting mountain building and biodiversity In the third section, you will read compelling examples from around the world exploring the links between mountains, climate and biodiversity Throughout the 31 peer-reviewed chapters, a non-technical style and synthetic illustrations make this book accessible to a wide audience A comprehensive glossary summarises the main concepts and terminology Readership: Mountains, Climate and Biodiversity is intended for students and researchers in geosciences, biology and geography. It is specifically compiled for those who are interested in historical biogeography, biodiversity and conservation.

Melt takes place where the surface of glaciers or ice sheets interacts with the atmosphere. While the processes governing surface melt are fairly well understood, the pathways of the meltwater, from its origin to the moment it leaves a glacier system, remain enigmatic. It is not even guaranteed that meltwater leaves a glacier or ice sheet. On Greenland, for example, only slightly more than 50% of the meltwater runs off. The remainder mostly refreezes within the so-called firn cover of the ice sheet. This eBook contains 11 studies which tackle the challenge of understanding meltwater retention in snow and firn from various angles. The studies focus both on mountain glaciers and on the Greenland ice sheet and address challenges such as measuring firn properties, quantifying their influence on meltwater retention, modelling firn processes and meltwater refreezing as well as unravelling the mechanisms within the recently discovered Greenland firn aquifers.

The introduction of the term periglacial by Lozinski in 1909 to describe the cold-climate conditions in the zone adjacent to, but beyond, the Pleistocene glaciers encouraged the separate development of geocryological and glaciological research. Geological and geomorphological processes at the interface between glaciers and permafrost have, as a result, been given less attention than they warrant, and the influence of one on the other has in many respects been neglected. This book includes a collection of papers that emphasize glacier-permafrost interactions. Papers consider permafrost and its influence on glacitectonic processes, glacial meltwater systems and ground-ice development in proglacial and ice-marginal environments. In addition, recent research findings are reported on paraglacial processes, permafrost evolution, rock glaciers, the formation of ice-wedge casts and periglacial slope evolution. It is hoped that this book will stimulate interest in the interface between glacial and periglacial systems, and encourage further collaborative research involving glaciologists and glacial geologists on the one hand, and geocryologists and permafrost scientists on the other.

The changing climate, the warming of the world and acid rain are among the greatest problems facing us at the end of the twentieth century. This book describes, for the first time, the effects of these phenomena on the high mountains and the forests of Europe. Mountains and the frozen regions (the cryosphere) not only play a major part in our climatic system, but are also central to our water supplies. Yet our glaciers are shrinking, our lakes and soils are becoming acidified, our forests are damaged and the whole fragile ecosystem of ranges like the Alps and the Caucasus is threatened. Nilsson and Pitt present the evidence and assess the probable effects of these changes on mountain society, tourism, water, flora and fauna. They also examine the uncertainties. Above all they look, too, at the best possible strategies in response to What is happening and at what the next steps should be. Originally published in 1991

Cyanoprokaryotes are probably the oldest organisms with plant metabolism. However, their cell structure and type of asexual reproduction prove their eubacterial origin. In spite of their existence from Precambrian onwards they have not lost their vitality, and still are able to colonize all possible biotopes, including very extreme environments (thermal springs up to 80 °C, rocks in extremely hot or cold deserts in both the tropics and Antarctica, hypersaline lakes and marshes, biotopes in volcanic regions, and other harsh habitats). This book is a review of all the cyanoprokaryotic taxonomic units, registered and recognizable from European natural biotopes, including the marine coasts. Our determination keys and taxonomic descriptions should permit the identification of natural populations, and should be related to known culture material. Numerous strains were isolated, kept in strain collections and used as important model organisms for experiments of various kinds. In culture only a few cyanoprokaryotes show the typical growth form known from nature, most others can be made to display their typical forms and life cycles by special procedures only. The identification of strains without previous knowledge of natural material needs to be carried out with special care. The aim of this book is to make possible the identification and standardization of known, morphologically and ecologically distinguishable cyanoprokaryotes that have been described from natural populations in Europe. Therefore, in the introductory part only data important for identification are presented. At the end of this chapter we append a list of basic literature, where all the detailed information necessary can be found. We have selected accurate drawings of the species described in the text. We also present illustrations of some non-European species if necessary for understanding the generic diacritical features or infrageneric diversity.

The Karakoram contains the greatest concentration of glaciers and most of the largest ice masses outside high latitudes. They comprise major stores and sources of fresh water in an otherwise extreme, continental, dry region. As many as 200 million people living downstream, in the valleys of the Indus and Yarkand Rivers, depend on melt waters from snow and ice. They are at risk from climate-change impacts on glaciers and water supply, and from hazards such as glacial lake outburst floods. Useful research initiatives go back to the nineteenth century, but coverage has generally been limited geographically and has not been continuous over time. It is almost 80 years since a monograph was devoted to the Karakoram glaciers. The book presents a comprehensive overview, including statistics for the ice cover, glacier mass balance and dynamics, glacierized landscapes, rock glaciers, water resources and environmental hazards. Published glaciological and related research is surveyed along with expedition reports and archival materials in several languages. The expanding potential of satellite coverage is exploited, but conditions and processes reported from field investigations are the main focus. Previously unpublished observations by the author are presented, based on some 45 years of work in the region. Broad understanding of the glacial environment is used to address emerging concerns about the High Asian cryosphere and the fate of its glaciers. These are discussed in relation to the pressing issues of water supply, environmental risk and sustainability. Questions of what is not known help identify much needed monitoring and research. The book is of interest to researchers, professionals, and those studying glaciers, mountain environments, water resources and environmental hazards. The topics discussed should be of concern for anyone involved in regional development and global change in South and Inner Asia.
