Available in PDF, EPUB and Kindle. Book excerpt: Wide coverage of soils and perennial cropping systems in the tropicsSynthesis of decades of researchChallenges assumptions on the benefits of plantations for soil fertilityIt is generally assumed that soil fertility decline is widespread in the tropics and that this is largely associated with annual cropping and subsistence farming. In contrast, perennial plant cover (as in plantation agriculture) provides better protection for the soil.This book reviews these concepts, focusing on soil chemical changes under different land-use systems in the tropics. These include perennial crops, annual crops and forest plantations. Two case studies, on sisal plantations in Tanzania and sugar cane in Papua New Guinea, are presented for detailed analysis. The author demonstrates that soil fertility decline is also a problem on plantations.

Download or read book High Altitude Tropical Biogeography written by François Vuilleumier and published by . This book was released on 1986 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: High Altitude Tropical Biogeography provides research workers and academics with a comprehensive overview of the biogeography of high tropical mountains, covering the origin, ecology, and evolution of plants and animals of this unique ecological zone. The climate in the high altitude mountain regions of the tropics is cold, resulting in flora and fauna which more closely resemble their counterparts thousand of miles to the north or south than comparable species in the lowland jungles only a few thousand meters below. These ecological "islands", besides being very important to the economies of the tropics, pose interesting questions of physiological adaptation, biogeography, and evolutionary relationships. With contributions from twenty-four international specialists who have devoted years to the study of cold mountain tropics, this book describes some of the most characteristic plant and animal components of the ecosystem. No other book of this scope and content exists on these tropical biotas.

Available in PDF, EPUB and Kindle. Book excerpt: Malaria has existed in Greece since prehistoric times. Its prevalence fluctuated depending on climatic, socioeconomic and political changes. The book focuses on the factors that contributed to the spreading of the disease in the years between independent statehood in 1830 and the elimination of malaria in the 1970s. By the nineteenth century, Greece was the most malarious country in Europe and the one most heavily infected with its lethal form, falciparum malaria. Owing to pressures on the environment from economic development, agrarian colonization and heightened mobility, the situation became so serious that malaria became a routine part of everyday life for practically all Greek families, further exacerbated by wars. The country’s highly fragmented geography and its variable rainfall distribution created an environment that was ideal for sustaining and spreading of diseases, which, in turn, affected the tolerance of the population to malaria. In their struggle with physical suffering and death, the Greeks developed a culture of avid quinine consumption and were likewise eager to embrace the DDT spraying campaign of the immediate post WW II years, which, overall, had a positive demographic effect.

Download or read book Saving a Million Species written by Lee Hannah and published by Island Press. This book was released on 2012-06-22 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research paper "Extinction Risk from Climate Change" published in the journal Nature in January 2004 created front-page headlines around the world. The notion that climate change could drive more than a million species to extinction captured both the popular imagination and the attention of policy-makers, and provoked an unprecedented round of scientific critique. Saving a Million Species reconsiders the central question of that paper: How many species may perish as a result of climate change and associated threats? Leaders from a range of disciplines synthesize the literature, refine the original estimates, and elaborate the conservation and policy implications. The book: examines the initial extinction risk estimates of the original paper, subsequent critiques, and the media and policy impact of this unique study presents evidence of extinctions from climate change from different time frames in the past explores extinctions documented in the contemporary record sets forth new risk estimates for future climate change considers the conservation and policy implications of the estimates. Saving a Million Species offers a clear explanation of the science behind the headline-grabbing estimates for conservationists, researchers, teachers, students, and policy-makers. It is a critical resource for helping those working to conserve biodiversity take on the rapidly advancing and evolving global stressor of climate change-the most important issue in conservation biology today, and the one for which we are least prepared.
