Book Description
The Amazon -that name was given to the biggest river on earth and is often used for the whole area of its basin too. This geographical region is currently referred to as Amazonia, thus emphasizing the peculiar character of its aquatic and terrestrial reaches. The Amazon embodied the dream of many a naturalist to explore what for a long time was a terra incognita. In recent years, however, Amazonia has emerged as a main centre for 'development' by some of the countries in which it lies and by foreign industrialized nations. The development projects and enterprises have aroused woridwide interest and have given rise to discussions on their aims and their consequences to the Amazonian nature. Limnological and ecological investigations in Amazonia started only about 40 years ago. The editor had the good fortune to partake in them from the very beginning. He spent his decisive years in Amazonia, and dedicated his life's work to that research and to that country and the Amazonian people. Nearing the end of his scicntific activities, hc is gratcful to bc ablc to summarizc in this book most of the knowledge we possess at present of Amazonian limnology and landscape ecology.

Book Description
This book covers the proceedings of a study week held to bring together the most varied experiences in the many disciplines which form the background of ecology. The purpose of the meeting was to examine the present state of knowledge and the need for research in order to gather the information necessary for action to protect the environment and biosphere. Many aspects of the anthropogenic effects on the atmosphere have been studied. However more research is needed to quantify the impact of the various chemicals on the changes occurring in the atmosphere. Acid rain formation mechanisms, although investigated, are not yet fully understood. It is thus necessary to program carefully our future, after further interdisciplinary research, in order to avoid irreversible damage to our environment. The guidelines of this action, as a result of the presentations and discussions, are reported in the conclusions. The main points stressed are: tropospheric chemistry, the problem of the conservation of the ozone layer, the growth of carbon dioxide and climate changes, atmospheric acidity, the effects of changes on water, soils and biota as well as the particular problems of the tropical world. The book will be ideal for postgraduates studying atmospheric chemistry and for environmental protection agencies.
