Book Description
Until relatively recently the valuable tropical montane cloud forests (hereaf ter usually referred to as TMCFs) of the world had scarcely come under the assaults experienced by the downslope montane and lowland forests. TMCFs are not hospitable environments for human occupation, and their remoteness (except in places near Andean high mountain settlements and in the Ethiopian Highlands) and difficult terrain have given them de facto protection. The ad jacent upper montane rain forests have indeed been under assault for timber, fuelwood, and for conversion to grazing and agriculture for many decades, even centuries in the Andes, but true cloud forest has only come under ex ploitation as these lower elevational resources have disappeared. They have also been "nibbled" at from above where there have been alpine grasslands under grazing pressure. Increasingly now, however, these cloud forest eco systems are being fragmented, reduced, and disturbed at an alarming rate. It is now becoming recognized that steps must be taken rapidly to increase our understanding of TMCF and to achieve their conservation, because: their water-capture function is extremely important to society; • their species endemism is high; they serve as refugia for endangered species being marginalized in these environments by increasingly transformed lower elevation ecosystems; they are relatively little studied; yet, their value to science is extremely high; they have low resilience to disturbance; vii viii Preface and many other reasons, which will be discussed subsequently in this publi cation.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
The global prominence of snakes in religion, myth, and folklore underscores our deep connection to them—but why, when few of us have firsthand experience? The answer, Isbell suggests, lies in snakes’ singular impact on primate evolution; predation pressure from snakes is ultimately responsible for the superior vision and large brains of primates.

Book Description
Giants, cannibals and other monsters were a regular feature of Renaissance illustrated maps, inhabiting the Americas alongside other indigenous peoples. In a new approach to views of distant peoples, Surekha Davies analyzes this archive alongside prints, costume books and geographical writing. Using sources from Iberia, France, the German lands, the Low Countries, Italy and England, Davies argues that mapmakers and viewers saw these maps as careful syntheses that enabled viewers to compare different peoples. In an age when scholars, missionaries, native peoples and colonial officials debated whether New World inhabitants could – or should – be converted or enslaved, maps were uniquely suited for assessing the impact of environment on bodies and temperaments. Through innovative interdisciplinary methods connecting the European Renaissance to the Atlantic world, Davies uses new sources and questions to explore science as a visual pursuit, revealing how debates about the relationship between humans and monstrous peoples challenged colonial expansion.
