Ever since the forest primeval, men and women have walked among the trees and admired their beauty and wondered at their size. How big are these magnificent things, anyway? We moderns are wont to measure, categorize and document, and so a book like this is born which is world-wide in scope and not only embraces space but also time. As the author, Al Carder, shows us in his study of forest giants the past is as important as the present. Many, many of our great trees have fallen and disappeared, some through fire and storm but more through the ravages of our own kind. Dr. Carder has not only traveled the world in search of the living giants, he has consulted the histories and records to identify those great trees that have been and gone, and his book is therefore an authoritative record of the world's super trees, past and present. Height is only one quality of greatness. Some trees are awesome in their ultimate form; their bole, their spread of canopy, their age. All these features are ardently noted by the author who describes more than 140 species. Forest Giants of the World will appeal to those who wonder about the location and the measurement of the Great Trees as well as to the specialist who requires more technical details about them.
“No one who loves elephants or how humans interact with wildlife should pass up Jacob Shell’s remarkable book.” —Dan Flores, author of Coyote America Giants of the Monsoon Forest journeys deep into the mountainous rainforests of Burma and India to explore the world of teak logging elephants and their intriguing alliance with humans. Jacob Shell’s narrative vividly depicts elephants’ extraordinary intelligence, and the complicated bond with individual human riders, a partnership that can last for decades. Giants of the Monsoon Forest reveals an unexpected relationship between evolution in the natural world and political struggles in the human one, while considering how Asia’s secret forest culture might offer a way to help protect the fragile spaces both elephants and humans need to survive.
A landmark volume celebrating the most remarkable trees on the planet, Pakenham takes readers on a voyage across four continents and introduces them to arbors of all shapes and sizes--dwarfs, giants, aliens, and monuments. Full-color photos.
The publication was prepared based on information provided by 86 countries, outcomes from regional and subregional consultations and commissioned thematic studies. It includes: •an overview of definitions and concepts related to Forest Genetic Resources (FGR) and a review of their value; •a description of the main drivers of changes; •the presentation of key emerging technologies; •an analysis of the current status of FGR conservation, use and related developments; •recommendations addressing the challenges and needs.

This up-to-date textbook of global vegetation ecology, which comprises the current state of knowledge, is long overdue and much-needed. It is a translation of the textbook “Vegetation der Erde” (Springer-Spektrum, Heidelberg). A short introductory chapter deals with the fundamentals of vegetation ecology that are of importance for the delimitation and characterization of the global vegetation presented in this book (chorology, evolution of plants, physiognomic and structural characteristics, phytodiversity and the human impact on it as well as general terminology concerning both plant growth forms and on vegetation structure types). In the following chapters the zonal and azonal vegetation from the tropics to the polar regions including high mountains is described and discussed. The main focus is on the characterization of interactions between the spatial location of plants and plant communities on the one hand and site conditions, historic and genetic processes, spatial and temporal patterns, ecophysiology and anthropogenic influences on the other hand. Additional information on specific topics is provided in 51 boxes.
A systematic investigation of growth in nature and society, from tiny organisms to the trajectories of empires and civilizations. Growth has been both an unspoken and an explicit aim of our individual and collective striving. It governs the lives of microorganisms and galaxies; it shapes the capabilities of our extraordinarily large brains and the fortunes of our economies. Growth is manifested in annual increments of continental crust, a rising gross domestic product, a child's growth chart, the spread of cancerous cells. In this magisterial book, Vaclav Smil offers systematic investigation of growth in nature and society, from tiny organisms to the trajectories of empires and civilizations. Smil takes readers from bacterial invasions through animal metabolisms to megacities and the global economy. He begins with organisms whose mature sizes range from microscopic to enormous, looking at disease-causing microbes, the cultivation of staple crops, and human growth from infancy to adulthood. He examines the growth of energy conversions and man-made objects that enable economic activities—developments that have been essential to civilization. Finally, he looks at growth in complex systems, beginning with the growth of human populations and proceeding to the growth of cities. He considers the challenges of tracing the growth of empires and civilizations, explaining that we can chart the growth of organisms across individual and evolutionary time, but that the progress of societies and economies, not so linear, encompasses both decline and renewal. The trajectory of modern civilization, driven by competing imperatives of material growth and biospheric limits, Smil tells us, remains uncertain.

Researched for more than three decades, this definitive work provides up-to-date descriptions of all the true conifers of the world, including 545 species of trees and shrubs. Written for accessibility to both horticultural and botanical audiences, it is the first comprehensive update of conifer taxonomy in nearly a century. Noted conifer taxonomist James E. Eckenwalder also discusses the relationships among the groups, practical usages, champion trees, fossil occurrences, and biology. New identification guides for the families and genera are based whenever possible on foliage features and thus should be easier to use than traditional conifer keys, which focus on seasonal, and often microscopic, cone characters. Eckenwalder shares the reasoning behind his taxonomic decisions, many of which are unique to this book, reflecting a comprehensive reevaluation of conifer classification. He also outlines the features sought in cultivars of each genus, particular cultivation concerns, and conifers recommended for cultivation under various conditions and to achieve different effects. Some 3,000 cultivars have been available in recent times, more than five times the total number of conifer species. Several hundred original illustrations include drawings of the seed cones for all genera as well as for representative species. Maps of the natural distribution of each genus allow for easy comparison of ranges. Handsome black-and-white photographs of species in their natural habitats and attractive color photos further enrich the volume. More than 100 images reproduce foliage of many genera as an aid in identification. With its unprecedented attention to detail and extensive bibliography, this major work is an essential reference for botanists, naturalists, and horticulturists.
