Book Description
The legacy of Alexander von Humboldt (1769–1859) looms large over the natural sciences. His 1799–1804 research expedition to Central and South America with botanist Aimé Bonpland set the course for the great scientific surveys of the nineteenth century, and inspired such essayists and artists as Emerson, Goethe, Thoreau, Poe, and Church. The chronicles of the expedition were published in Paris after Humboldt’s return, and first among them was the 1807 “Essay on the Geography of Plants.” Among the most cited writings in natural history, after the works of Darwin and Wallace, this work appears here for the first time in a complete English-language translation. Covering far more than its title implies, it represents the first articulation of an integrative “science of the earth, ” encompassing most of today’s environmental sciences. Ecologist Stephen T. Jackson introduces the treatise and explains its enduring significance two centuries after its publication.

Book Description
The first and so far only Plant Geography of Chile was written about 100 years ago, since when many things have changed: plants have been renamed and reclassified; taxonomy and systematics have experienced deep changes as have biology, geography, and biogeography. The time is therefore ripe for a new look at Chile’s plants and their distribution. Focusing on three key issues – botany/systematics, geography and biogeographical analysis – this book presents a thoroughly updated synthesis both of Chilean plant geography and of the different approaches to studying it. Because of its range – from the neotropics to the temperate sub-Antarctic – Chile’s flora provides a critical insight into evolutionary patterns, particularly in relation to the distribution along the latitudinal profiles and the global geographical relationships of the country’s genera. The consequences of these relations for the evolution of the Chilean Flora are discussed. This book will provide a valuable resource for both graduate students and researchers in botany, plant taxonomy and systematics, biogeography, evolutionary biology and plant conservation.

Book Description
Historical Geography of Crop Plants is devoted to a variety of staple and food crops, as well as fodder, fiber, timber, rubber, and other crops. The origins and histories of many of these crops have been clarified only recently by new research. The book has been arranged alphabetically by family and higher taxa for easy reference. Within families, species and cultivars are listed chronologically and geographically. The taxonomy and geography of probable wild progenitors have been outlined, and archeological evidence (when available) and historical evidence on region and domestication are traced. The subsequent evolution and spread of many domesticated species are examined, and the reasons behind the diversity in crop histories are explored. Historical Geography of Crop Plants will be a useful reference for botanists, economic botanists, ethnobiologists, agronomists, geographers, and others interested in the subject.

Book Description
Originally published in 1981 Historical Plant Geography is an introductory treatment of historical plant geography and stresses the basic theoretical frame of the subject. The book is about neither the study of vegetation nor the concept of the ecosystem, instead focusing on the much older tradition concerned with analysing the geographical distribution of individual species and natural plant groups. Important areas are discussed, such as global plate tectonics and sea-floor spreading, plant maps are introduced and there is a basic treatment of recent advances in plant taxonomy. The book will appeal to students and academics of geography, botany, ecology and environmental sciences.

Book Description
This anthology provides an historical overview of the scientific ideas behind environmental prediction and how, as predictions about environmental change have been taken more seriously and widely, they have affected politics, policy, and public perception. Through an array of texts and commentaries that examine the themes of progress, population, environment, biodiversity and sustainability from a global perspective, it explores the meaning of the future in the twenty-first century. Providing access and reference points to the origins and development of key disciplines and methods, it will encourage policy makers, professionals, and students to reflect on the roots of their own theories and practices.

Book Description
Plants are fundamental players in human lives, underpinning our food supply and contributing to the air we breathe, but they are easy to take for granted and have received insufficient attention in the social sciences. This book advances understanding of human-plant relations using the example of wheat. Theoretically, this book develops new insights by bringing together human geography, biogeography and archaeology to provide a long term perspective on human-wheat relations. Although the relational, more-than-human turn in the social sciences has seen a number of plant-related studies, these have not yet fully engaged with the question of what it means to be a plant. The book draws on diverse literatures to tackle this question, advancing thinking about how plants act in their worlds, and how we can better understand our shared worlds. Empirically, the book reports original ethnographic research on wheat production, processing and consumption in a context of globalisation, drought and climate change and traces the complex networks of wheat using a methodology of 'following' it and its people. The ethnobotanical study captures a number of moments in the life of Australian wheat; on the farm, at the supermarket, in the lives of coeliac sufferers, in laboratories and in industrial factories. This study demands new ways of thinking about wheat geographies, going beyond the rural landscape to urban and industrial frontiers, and being simultaneously local and global in perspective and connection.

Book Description
Phytomass and Primary Production of the Various Vegetational Zones and of the Entire Biosphere The biosphere is that thin layer at the earth's surface in which living organisms exist and biological cycling takes place. It includes the upper horizons of the soil in which plants root, the atmosphere near the ground, (insofar as organisms penetrate this space), and all the surface waters. More than 99% of the earth's biomass is phytomass, to which we shall limit our discussion. Amounts of phytomass are distinctly related to vegeta tional zones. Because accurate determination of phytomass and primary production is difficult, only gross estimates have been available until recently. However, in 1970, Bazilevich et al. published (in Russian) more accurate calculations, based on the rapidly accumulating literature, for the various thermal zones and bioclimatic regions of the earth. These authors calculated mean phyto mass and mean annual primary production for the various regions as dry mass (in tons) per hectare. On the basis of measurements of the areas covered by the individual regions, excluding rivers, lakes, glaciers, and permanent snow, total phytomass and total annual primary production for the various regions were obtained (see table). The sum of these figures is the phytomass and annual production of the land surface of the earth. In addition, the table gives corresponding data for the waters of the earth. The values involved are potential i. e. , they are based on natural vegetation uninfluenced by man.

Book Description
This volume provides an accessible scientific introduction to the historical geography of Tropical Pacific Islands, assessing the environmental and cultural changes they have undergone and how they are affected currently by these shifts and alterations. The book emphasizes the roles of plants, animals, people, and the environment in shaping the tropical Pacific through a cross-disciplinary approach involving history, geography, biology, environmental science, and anthropology. With these diverse scientific perspectives, the eight chapters of the book provide a comprehensive overview of Tropical Pacific Islands from their initial colonization by native peoples to their occupation by colonial powers, and the contemporary changes that have affected the natural history and social fabric of these islands. The Tropical Pacific Islands are introduced by a description of their geological formation, development, and geography. From there, the book details the origins of the island's original peoples and the dawn of the political economy of these islands, including the domestication and trade of plants, animals, and other natural resources. Next, readers will learn about the impact of missionaries on Pacific Islands, and the affects of Wold War II and nuclear testing on natural resources and the health of its people. The final chapter discusses the islands in the context of natural resource extraction, population increases, and global climate change. Working together these factors are shown to affect rainfall and limited water resources, as well as the ability to sustain traditional crops, and the capacity of the islands to accomodate its residents.
