Book Description
Bryophytes, especially mosses, represent a largely untapped resource for monitoring and indicating effects of climate change on the living environment. They are tied very closely to the external environment and have been likened to 'canaries in the coal mine'. Bryophyte Ecology and Climate Change is the first book to bring together a diverse array of research in bryophyte ecology, including physiology, desiccation tolerance, photosynthesis, temperature and UV responses, under the umbrella of climate change. It covers a great variety of ecosystems in which bryophytes are important, including aquatic, desert, tropical, boreal, alpine, Antarctic, and Sphagnum-dominated wetlands, and considers the effects of climate change on the distribution of common and rare species as well as the computer modeling of future changes. This book should be of particular value to individuals, libraries, and research institutions interested in global climate change.

Book Description
This volume presents a synthesis of new information about the responses of bryophytes and lichens to changing environmental conditions, particularly those brought about by human activities. Bryophytes and lichens are often treated independently, but as they commonly exist in association with each other and share similar characteristics, they are here described together. The environmental sensitivity of both types of organisms is truly remarkable. At various times the use of one group or the other has been recommended to indicate the presence of particular mineral deposits (geological prospecting), soil and site conditions (forestry), level of atmosphere and aquatic pollutants (biomonitoring), ages of rock surfaces (lichenometry), and historical continuity of forests cover (bioindication). Topics covered in this book include physiology, distribution, ecological function, and response to pollution and land management of these organisms.

Book Description
With detailed essays on the Arctic's environment, wildlife, climate, history, exploration, resources, economics, politics, indigenous cultures and languages, conservation initiatives and more, this Encyclopedia is the only major work and comprehensive reference on this vast, complex, changing, and increasingly important part of the globe. Including 305 maps. This Encyclopedia is not only an interdisciplinary work of reference for all those involved in teaching or researching Arctic issues, but a fascinating and comprehensive resource for residents of the Arctic, and all those concerned with global environmental issues, sustainability, science, and human interactions with the environment.

Book Description
Although Antarctic finfish have been exploited for more than two decades and many stocks now appear to be overfished, this is the first detailed account of this fishery. The book begins by giving a comprehensive description of Antarctic fish biology and ecology, the thorough understanding of which is a prerequisite to sound management of the fishery. Subsequent sections consider the course of finfish exploitation and the present state of exploited fish stocks in the Southern Ocean. The author concludes by proposing more effective management methods for the fish resources of the Southern Ocean in light of the Convention on the Conservation of Antarctic Marine Living Resources.

Book Description
In arid lands, where vegetation is sparse or absent, the open ground is not bare but generally covered by a community of small, highly specialized organisms. Cyanobacteria, algae, microfungi, lichens, and bryophytes aggregate soil particles to form a coherent skin - the biological soil crust. It stabilizes and protects the soil surface from erosion by wind and water, influences water runoff and infiltration, and contributes nitrogen and carbon to desert soils. Soil surface disturbance, such as heavy livestock grazing, human trampling or off-road vehicles, breaks up the fragile soil crust, thus compromising its stability, structure, and productivity. This book is the first synthesis of the biology of soil crusts and their importance as an ecosystem component. Composition and functioning of different soil-crust types are discussed, and case studies are used to show the impact of crusts on landscape hydrology, soil stability, nutrient cycles, and land management.
