A Revision of the Genus Polylepis (Rosaceae: Sanguisorbeae)
Species of Polylepis are shrubs or trees native to the mid- and high-elevation tropical Andes. Some species of Polylepis form woodlands growing well above normal treeline within grass and scrub associations at elevations over 5000 m. Consequently, Polylepis appears to be the highest natural occurring arborescent angiosperm genus in the world. The physiological basis allowing such high altitude growth is not understood, but evidence indicates that woodlands at these elevations are restricted to microsites where ecological conditions are similar to those of lower altitudes. The genus is distinct from other rosaceous members of the tribe Sanguisorbeae and is interpreted here as consisting of th...
The Ecology of Seeds
What determines the number and size of the seeds produced by a plant? How often should it reproduce them? How often should a plant produce them? Why and how are seeds dispersed, and what are the implications for the diversity and composition of vegetation? These are just some of the questions tackled in this wide-ranging review of the role of seeds in the ecology of plants. The authors bring together information on the ecological aspects of seed biology, starting with a consideration of reproductive strategies in seed plants and progressing through the life cycle, covering seed maturation, dispersal, storage in the soil, dormancy, germination, seedling establishment, and regeneration in the field. The text encompasses a wide range of concepts of general relevance to plant ecology, reflecting the central role that the study of seed ecology has played in elucidating many fundamental aspects of plant community function.
Racial Subordination in Latin America
There are approximately 150 million people of African descent in Latin America yet Afro-descendants have been consistently marginalized as undesirable elements of the society. Latin America has nevertheless long prided itself on its absence of U.S.-styled state-mandated Jim Crow racial segregation laws. This book disrupts the traditional narrative of Latin America's legally benign racial past by comprehensively examining the existence of customary laws of racial regulation and the historic complicity of Latin American states in erecting and sustaining racial hierarchies. Tanya Katerí Hernández is the first author to consider the salience of the customary law of race regulation for the contemporary development of racial equality laws across the region. Therefore, the book has a particular relevance for the contemporary U.S. racial context in which Jim Crow laws have long been abolished and a "post-racial" rhetoric undermines the commitment to racial equality laws and policies amidst a backdrop of continued inequality.
Biodiversity Islands: Strategies for Conservation in Human-Dominated Environments
This book is intended to provide an overview for the identification and establishment of biodiversity islands. It presents examples and case studies where the biodiversity islands approach is being used in a variety of locations and contexts worldwide. It will contribute to design parameters on appropriate sizing and spatial distribution of biodiversity islands in order to be effective in conservation and regeneration across the landscape, using integrated landscape management approaches. This book is essential given the current worldwide trend of habitat destruction and the need to preserve biodiversity and its values. The chapters are organized in five sections. The first section provides ...
Forests and Global Change
Forests hold a significant proportion of global biodiversity and terrestrial carbon stocks and are at the forefront of human-induced global change. The dynamics and distribution of forest vegetation determines the habitat for other organisms, and regulates the delivery of ecosystem services, including carbon storage. Presenting recent research across temperate and tropical ecosystems, this volume synthesises the numerous ways that forests are responding to global change and includes perspectives on: the role of forests in the global carbon and energy budgets; historical patterns of forest change and diversification; contemporary mechanisms of community assembly and implications of underlying drivers of global change; and the ways in which forests supply ecosystem services that support human lives. The chapters represent case studies drawn from the authors' expertise, highlighting exciting new research and providing information that will be valuable to academics, students, researchers and practitioners with an interest in this field.
Evolution and Social Life
Evolution is among the most central and most contested of ideas in the history of anthropology. This book charts the fortunes of the idea from the mid-nineteenth century to recent times. By comparing biological, historical, and anthropological approaches to the study of human culture and social life, it lays the foundation for their effective synthesis. Far ahead of its time when first published, the book anticipates debates at the forefront of contemporary thinking. Revisiting the work after almost thirty years, Tim Ingold offers a substantial new preface that describes how the book came to be written, how it was received and its bearing on later developments. Unique in scope and breadth of theoretical vision, Evolution and Social Life cuts across the boundaries of natural science and the humanities to provide a major contribution both to the history of anthropological and social thought, and to contemporary debate on the relationship between human nature, culture, and social life.
Conservation and Ecology
Discusses the history of ecology and biodiversity conservation, stressing the importance of maintaining biologically diverse ecosystems and helping prevent unnatural extinctions of plant and animal species.
Routledge Handbook of Forest Ecology
The Routledge Handbook of Forest Ecology is an essential resource covering all aspects of forest ecology from a global perspective. This new edition has been fully revised and updated throughout to reflect the profound and unprecedented changes in both forests and climates since the publication of the first edition in 2015. The handbook reflects key developments in the field of forest dynamics and large-scale processes, as well as the changes that are now manifesting in different types of forests across the globe as a result of climate change. It covers both natural and managed forests, from boreal, temperate, sub-tropical and tropical regions of the world. In this second edition, the breadt...

The Monfort Plan
The Monfort Plan is a five-year, forward looking plan to eradicate extreme poverty from the developing world, and details how microfinance has made a difference to developing countries. This book proposes a new institution based in the developing world with the potential to provide a basic, free, and universal service in the areas of water, sanitation, healthcare, and education to the extreme poor worldwide. The provision will be subject to a certain degree of conditionality in areas ranging from corruption to legal environment. The new institution will be established in a new international territory based within a specific country in Subsaharan Africa and will emerge in 2015. In The Monfort...
