This important volume reviews the status of investigations aimed at deciphering the geologic, biogeographic, and archaeological records for the Quaternary Era—the last million years of geologic time-for the area of continental United States. Over eighty Quaternary scientists have contributed to the fifty-five chapters divided into four main parts. Part 1 treats the areal geology, with emphasis on the stratigraphy of the glaciated areas east of the Rocky Mountains, unglaciated eastern and central United States, and western United States. Part 2 deals with biogeography: phytogeography and palynology, animal geography and evolution. Part 3 deals with archaeology prehistory in the northeastern states, southeastern states, plains, desert west, and Pacific Coast including Alaska. Part 4 covers many diverse Quaternary studies on—the continental shelves, isotope geochemistry, paleopedology, the geochemistry of some lake sediments, paleohydrology, glaciers and climate, volcanic-ash chronology, paleomagnetism, neo-tectonics, dendrochronology, and theoretical paleoclimatology. Originally published in 1965. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

From single-celled organisms in Black Sea sand to endemic cave crustaceans, from mountain glacial relict insects to the most diverse bird fauna in Europe, the fauna of Bulgaria has been a subject of study for more than a century. This is the first English language survey of all vertebrate and many key invertebrate groups of Bulgaria, their faunistics, origin, geographical and ecological distribution, and conservation issues.

The inspiration for this book came from our ten years of journeys and wanderings through the varied landscapes of Arabia, and in particular through those of its hospitable southeastern corner, Oman. We owe a particular debt to Sultan Qaboos University, which during this time has provided us with both a stimulating working environment and a home. Transliteration of Arabic place and other names into English script is a task fraught with difficulties. We have followed 'accepted' spellings wherever these were not contrary to our common sense, and in other cases we have rendered names into Roman English script using phonetic spellings. Our main task in this respect was to ensure conformity between the fIfteen contributing authors. Diacritical signs have mostly been avoided, since their use is neither widely followed nor readily understood. Arabic words which have been commonly taken into the English language, such as 'sabkha' for a salt flat and 'wadi' for a valley with a seasonal watercourse, are not italicised in usage. However, other Arabic terms which are occasionally used in English but not as widely known, such as harrah for a basaltic lava fIeld and hima for a traditional grazing reserve, are italicised throughout the text.

The Mexican Plateau, in its magnificent dimensions and material wealth, stood among the first and perhaps most alluring discoveries of European explorers. Bur ied deeper in the verbal histories of a now vanquished people, the American Indians, must be the primordial human awareness of the inverted complex triangle that dominates the Mexican topography, climate and biota. It always has been viewed by man as a source of wealth and a center of authority. The plateau is the pillar upon which all Mexican conquerors have erected their capitols, tilled their crops and mined for their treasure, and from which they dispersed the forces of their authority. Ironically, the same size and diversity that give the plateau its value, also make it an immense barrier. Its broad desert and three to five thousand meter high crests constitute severe obstacles in the path of North American man. What has just been said of mankind in general, can be applied to the biologist in particular. He too has termed the goliath southern plateau as the crucible of the arid biotas of the continent (i. e. , 'Madro-Tertiary'). The biologist found the plateau to be a region of tremendous richness and diversity. But he also has been inhibited both physically and intellectually by its high mountain and vast desert barriers.

One of the main problems and aims of nature conservation in Europe is to protect semi-open landscapes. The development during the past decades is characterized by an ongoing intensivation of land use on the one hand, and an increasing number of former meadows and pastures lying fallow caused by changing economic conditions on the other hand. In several countries the estabishment of larger "pasture landscapes" with a mixed character of open grassland combined with shrubs and forests has been recognized as one solution to this problem. The book gives an overview of the European projects concerning to this topic - nature conservation policy and strategies, scientific results and practical experiences creating large scale grazing systems.

This book provides an overview of arid and semi-arid lands conditions, their general characteristics, methods of management, conservation, exploitation and reclamation. It also focuses on how to utilize the potential of arid lands with the minimum manipulation and alteration. Arid and semi-arid areas represent a major part of natural ecosystems not only in Iran, but around the world, and mismanagement and inappropriate exploitation of these areas may lead to further gradual degradation. As such, an understanding of the characteristics of these areas is vital if they are to be conserved and reclaimed.
