DOWNLOAD EBOOKA core textbook series that aims to provide students with accessible, up-to-date accounts of Ecogeography - the marriage of ecology with geography - in the primary terrestrial and marine environments. This is the first book in the series on Mediterranean Ecogeography. Biological diversity in the Mediterranean Basin is amongst the highest of any region on earth, both in terms of total species numbers and endemism. The flora is estimated at about 25,000 species of flowering plants and ferns, compared with about 6000 species in non-Mediterranean Europe. About 50% of these are endemic. Diversity amongst vertebrate animals is also high, though endemism rates are lower than for plants. The high levels of diversity contribute to, and are a reflection of, the considerable variability of landscape. This results from a combination of factors including geological and tectonic history, relief and physiography, climate, geomorphological processes, hydrology, soils, the incidence of fires and impact of human activities. The landscapes of the Mediterranean Basin are thus varied and fragmented; a mosaic of ecosystems and communities. Mediterranean Ecogeography aims to examine and explain this heterogeneity, and the approach is focused on the ecogeography of the region. Analysing the factors which account for the present distributions of plants and animals, and the functioning of ecosystems within the Mediterranean Basin can help in the understanding of the relationship between people and natural ecosystems. A key to the conservation of these ecosystems is the wise use of resources, biological and physical. In addition, it is vital to assess how the natural environments of the region will respond to further change. In the last twenty years, understanding of the functioning of mediterranean-type ecosystems has advanced through several international projects. This book draws upon the findings of these, and other research in the Mediterranean Basin, to present a comprehensive text on a key region of the world, and the problems and prospects of its environmental exploitation.

DOWNLOAD EBOOKNo other disjunct pieces of land present such striking similarities as the widely sepa 1 rated regions with a mediterranean type of climate, that is, the territories fringing the Mediterranean Sea, California, Central Chile and the southernmost strips of South Mrica and Australia. Similarities are not confined to climatic trends, but are also reflected in the physiognomy ofthe vegetation, in land use patterns and frequently in the general appearance of the landscape. The very close similarities in agricultural practices and sometimes also in rural settlements are dependent on the climatic and edaphic analogies, as well as on a certain commonality in qdtural history. This is certainly true for the Mediterranean Sea basin which in many ways represents a sort of ecological-cultural unit; this is also valid for CaUfornia and Chile, which were both settled by Spaniards and which showed periods of vigorous commercial and cultural interchanges as during the California gold rush. One other general feature is the massive interchange of cultivated and weed species of plants that has occurred between the five areas of the world that have a mediterranean-type climate, with the Mediterranean basin region itself as a major source. In spite of their limited territorial extension, probably no other parts of the world have played a more fundamental role in the history of mankind. Phoenician, Etruscan, Hellenic, Jewish, Roman, Christian andArab civilizations, among others,haveshapedmanyofman's present attitudes, including his position and perception vis-a-vis nature.

DOWNLOAD EBOOKThe regions of the world which experience a mediterranean type climate, with a cool wet season alternating with a hot dry summer, contain some of the world's most attractive landscapes. In the Old World, the mediterranean landscapes became the cradle of civilization; other mediterranean areas of the world have attracted considerable populations for many centuries. These large human populations have exerted consid erable stress on the fragile ecosystems which developed in these sunny, but droughted, fire-prone land scapes. The mediterranean landscape has thus become one of the most threatened in the world. In recent years much has been learned about the structure and function of mediterranean-type ecosystems (Di Castri and Mooney 1973, Mooney 1977, Thrower and Bradbury 1977, Mooney and Conrad 1977, Specht 1979, 1981, Miller 1981, Di Castri et at. 1981, Conrad and Oeche11982, Queze11982, Margaris and Mooney 1981, Kruger et ai. 1983, Long and Pons 1984, Dell et ai. 1986, Tenhunen et ai. 1987). Much of this research has been fostered under the International Biological Program (IBP), UNESCO Man and the Biosphere Program (MAB) and, recently, the International Society of Mediterranean Ecologists (ISOMED). To facilitate intercontinental comparisons, many of these studies have concentrated on a limited number of intensive sites thought to be representative of a general region.

DOWNLOAD EBOOKThe biological effects of global warming should be of concern to all thinking individuals, for warming could cause profound disruption of natural ecosystems and could threaten many species with extinction. This important book--the first to discuss in detail the consequences of global warming for ecosystems--includes commentary by distinguished scientists on many aspects of this critical problem. Experts describe responses of animals and plants to previous climate changes, interactions between various environmental components (precipitation and soil chemistry, for example), and synergisms between climate change and human activities such as deforestation. They consider many specific ecosystems, including tropical forests, the deciduous forests of eastern North America, the forests of the Pacific Northwest, Mediterranean-type ecosystems in California, arctic tundra, and arctic marine systems. Offering discussions that are both factual and speculative, the volume points the way to future investigations of the implications of global warming.

DOWNLOAD EBOOKThe book is concerned principally with geobotanical mapping. Geobotany is a broad science that deals with the study of species and of vegetation communities in relation to the environment; it includes other, perhaps more familiar sciences, such as plant geography, plant ecology, and chorology, and phytosociology (plant sociology). Geobotanical cartography is a field of thematic cartography that deals with the interpretation and representation, in the form of maps, of those spatial and temporal phenomena that pertain to flora, vegetation, vegetated landscapes, vegetation zones, and phytogeographical units. The production of a geobotanical map represents the last stage in a cognitive process that begins with observations in the field and continues with the collection of sample data, interpretation of the phenomena observed, and their appropriate cartographic representation; geobotanical cartography is closely tied to the concepts and scope of geobotany in general

DOWNLOAD EBOOKIn the wake of the Second World War, internationalists identified science as both the cause of and the solution to world crisis. Unless civilization learned to control the unprecedented powers science had unleashed, global catastrophe was imminent. But the internationalists found hope in the idea of world government. In The Postwar Origins of the Global Environment, Perrin Selcer argues that the metaphor of “Spaceship Earth”—the idea of the planet as a single interconnected system—exemplifies this moment, when a mix of anxiety and hope inspired visions of world community and the proliferation of international institutions. Selcer tells the story of how the United Nations built the international knowledge infrastructure that made the global-scale environment visible. Experts affiliated with UN agencies helped make the “global”—as in global population, global climate, and global economy—an object in need of governance. Selcer traces how UN programs such as UNESCO’s Arid Lands Project, the production of a soil map of the world, and plans for a global environmental-monitoring system fell short of utopian ambitions to cultivate world citizens but did produce an international community of experts with influential connections to national governments. He shows how events and personalities, cultures and ecologies, bureaucracies and ideologies, decolonization and the Cold War interacted to make global knowledge. A major contribution to global history, environmental history, and the history of development, this book relocates the origins of planetary environmentalism in the postwar politics of scale.
