Description :


This book is the third in aseries of publications devoted to the biogeographieal and ecological research in the Southern Hemisphere, published in the "Monographiae Biologicae". After dealing with Australia (vol. VIII) and Southern Africa (Vol. XIV) it was thought essential to include Antarctiea in this series. Ever since the expedition of the "Belgiea" made the first suc cessful wintering within the antarctie circle in 1898 and brought back a very rieh harvest of scientific data, Belgium kept a vivid interest in Antarctiea and took an active part in the modern and international exploration of this vast continent. As part of their programs for the International Geophysieal Year (I. G. Y. ) twelve nations established permanent or semi-permanent bases on the Antarctie Continent or on subantarctie islands. Thus a new era of vast and free international scientific collaboration in the Antarctie was opened and it culminated in the formulation and the signing of the Antarctic Treaty (Washington 1959). It was recognized and accepted that "Antarctiea" shall be used for peaceful purposes only and "Freedom of scientific investigation in Antarctiea and coopera tion toward that end, as applied during the I. G. Y. , shall continue . . " In order to organize this collaboration e. g. by full exchange of programs and resuIts a "Special Committee on Antarctie Research" (S. C. A. R. ) was founded in 1957.

Description :


There has been an increasing interest in bryophyte ecology over the past 100 or so years, initially of a phytosociological nature but, additionally, in recent years, of an experimental nature as well. Early studies of bryophyte communities have led to detailed investigations into the relationships between the plants and their environment. Ecological papers, the large number of which is evidenced by the length of the bibliographies in the subsequent chapters, have appeared in numerous journals. Yet, apart from review chapters, by H. Gams and P. W. Richards in Manual of Bryology, edited b:; H. Verdoorn in 1932 and chapters in E. V. Watson's Structure and Life of Bryophytes, Prem Puri's Bryophytes - A Broad Perspective and D. H. S. Richardson's The Biology of Mosses, published in 1972,1973 and 1981 respectively, no general accounts of bryophyte ecology have been published. Although the Bryophyta is a relatively small division of plants, with between 14000 and 21000 species the interest that they have aroused is out of all proportion to the size either of the plants or of the division. It is evident, however, that despite their relative insigni ficance they play an important ecological role, especially in extreme environments and, in the case of bryophytes in tropical cloud forests and of Sphagnum, may even be a dominant factor in the ecology of the area concerned.

Description :


Highlighting twenty years of U.S. scientific research conducted since the International Geophysical Year (IGY) of 1957-58, this volume marks a turning point in the history of polar investigations and provides a lucid summary of the contributions of many distinguished scientists. The authors provide an overview of major polar research programs, past and present; explore concepts derived, from highly interrelated aspects of physical and life sciences; and seek to offer a glimpse of future polar science and polar development. The introduction briefly describes major physical, biological, and interdisciplinary research programs, as well as the magnitude, extent, and international character of contemporary polar science. Twenty years of polar biological investigations are then reviewed, and subsequent chapters address principles and advances in meteorology, physical oceanography, glaciology, and the geological evidence that hears on the origin of Antarctica. These physical sciences delineate a matrix for the polar biospheres and provide a background for understanding the major categories of structure and dynamic functioning of the marine ecosystem, polar marine mammals, adaptational physiology, and terrestrial biotic adaptations.

This text is a history of the world's oldest global conservation body - the World Conservation Union, established in 1948 as a forum for governments, non-governmental organizations and individual conservationists. The author draws on unpublished archives to reveal the often turbulent story of the IUCN and its achievements in, and influence on, conservation and environmental policy worldwide - establishing national parks and protected areas and defending threatened species.
