Book Description
This technical document supports the Forest Service's requirement to assess the status of renewable natural resources as mandated by the Forest and Rangeland Renewable Resources Planning Act of 1974. It updates past reports on the trends and geographic patterns of species formally listed as threatened or endangered under the Endangered Species Act of 1973. We compare the geographic occupancy of threatened and endangered species at the county-level against the geographic occupancy of a broader set of species thought to be at risk of extinction. This is done to determine if new areas where species rarity may be concentrated emerge. Here we document whether past trends and geographic occupancy patterns have changed over time, thereby providing resource planners and conservation practioners with updated information on where they should focus biodiversity conservation efforts.

Book Description
The forestlands of the U.S. tell a fascinating story about humankind and its relationship with the land. It is a story of trial and error, of consumption and conservation, and of conflict and collaboration. But most of all, it is a story of re-growth, renewal, and abundance. Through words, statistics, and graphs, this report tells this story. Contents: Historical Trends; What and Where are America¿s Forests (AF); Who Owns AF?; Conservation of AF; Biodiversity, Wildlife, Water and Non-timber Forest Products; Recreational Use; Growth, Harvesting, and Reforestation; Carbon Sequestration; AF in a Global Context; Certification; Threats; Forest Divestiture; Wood and Paper Products; Forest Products Markets; and Econ. Importance of a Healthy Forest Industry. Illus.

Book Description
Coevolution—reciprocal evolutionary change in interacting species driven by natural selection—is one of the most important ecological and genetic processes organizing the earth's biodiversity: most plants and animals require coevolved interactions with other species to survive and reproduce. The Geographic Mosaic of Coevolution analyzes how the biology of species provides the raw material for long-term coevolution, evaluates how local coadaptation forms the basic module of coevolutionary change, and explores how the coevolutionary process reshapes locally coevolving interactions across the earth's constantly changing landscapes. Picking up where his influential The Coevolutionary Process left off, John N. Thompsonsynthesizes the state of a rapidly developing science that integrates approaches from evolutionary ecology, population genetics, phylogeography, systematics, evolutionary biochemistry and physiology, and molecular biology. Using models, data, and hypotheses to develop a complete conceptual framework, Thompson also draws on examples from a wide range of taxa and environments, illustrating the expanding breadth and depth of research in coevolutionary biology.

Book Description
A synthesis of present understanding of the structure of the geographic ranges of species, which is a core issue in ecology and biogeography with implications for many of the environmental issues presently facing humankind.

Book Description
There are nearly 6,000 mammalian species, among them our own. Research on our evolutionary cousins has a long history, but the last 20 years have seen particularly rapid progress in disentangling the interrelationships and evolutionary history of mammals. The present volume combines up-to-date reviews on mammalian phylogenetics with paleontological, taxonomic and evolutionary chapters and also summarizes the historical development of our insights in mammalian relationships, and thus our own place in the Tree of Life. Our book places the present biodiversity crisis in context, with one in four mammal species threatened by extinction, and reviews the distribution and conservation of mammalian diversity across the globe. This volume is the introductory tome to the new Mammalia series of the Handbook of Zoology and will be essential reading for mammalogists, zoologists and conservationists alike.

Book Description
Invasive species have inspired concern for many reasons, including economic and environmental impacts in specific jurisdictions within particular countries. However, it is apparent that for some invasive plant species, political borders offer only weak barriers because these species have succeeded in invading many countries, emerging as threats at a global level. With this level of threat, a number of books on invasive plants and invasive species in general have been published in recent years, but none explicitly provides “global” coverage, perhaps because it is only recently that the full geographical, economic and environmental implications of widespread spread and adaptive nature of these particular invasive plants have been recognized. We plan to make this volume unique by profiling plant invasions in explicitly geographical contexts; on the world continents (Chapters 5-11), as well as islands (Chapter 12) and mountains (Chapter 13). This global approach is supported by an overview of invasion biology and recent advances (Chapter 1) and how different communities differ in invasibility (Chapter 2). Global factors influencing invasion are introduced in Chapter 3 (globalized trade) and Chapter 4 (climate change). Key species are profiled through geographic treatments, continent by continent (Chapters 5-11), and for islands (Chapter 12) and mountains (Chapter 13). The impact of invasive plants is highlighted in Chapter 14, both in biotic and economic terms, partly to counter the tendency for the young field of invasion biology to rely too much on anecdotal evidence. This chapters is also designed to bring home the message that these are serious problems that must be dealt with, as covered in the subsequent chapters. The book concludes with three chapters casting light on solutions to the many problems described in the rest of the volume. Chapter 15 features new, innovative technologies that are being developed to monitor and manage invasive plants, and Chapter 16 presents comprehensive strategies for public education and implementation of management on local and global scales. Chapter 17 describes different future scenarios depending on current trends in plant invasion and its management, just as climate change predictions employ various scenarios to project the future. The future is very much up to us, as humanity grapples with the question of how best to strategically meet the problems of global invasive plant problems that we ourselves have created that is further challenged by a changing climate. We are confident that this book will be of interest to invasion biologists, resource managers, and the legion of others who must deal with these invasive plants across the globe on a daily basis.
