Book Description
This book begins with a brief account of the extraordinary sequence of events that led to emergence of grasslands as major vegetation formations that now occupy some of the driest and hottest and the highest and coldest on earth as well as vast steppes and prairies in more temperate climes. It is the story of grasses successfully competing with forests and woodlands, aided and abetted by grazing herbivores and by humans and their use of fire as a tool. It is a story of adaptation to changing climates and the changing biophysical environments. A major focus of the book is the Palaearctic biogeographic realm that extends over some 45 million km2 and thus more than 1/3 of the terrestrial ice-free surface on Earth. It comprises extensive grasslands of different types and origin, which can be subdivided into (1) natural grasslands with (1a) steppes (climatogenic in dry climates), (1b) arctic-alpine grasslands (climatogenic in cold climates) and (1c) azonal and extrazonal grasslands (pedogenic and topogenic) as well as (2) secondary grasslands created and sustained by human activities, such as livestock grazing, mowing or burning. Grasslands of the Palaearctic do not only form a major basis for the agriculture of the region and thus its food supply, but are also crucial for other ecosystem services and host a supra proportional part of the realm’s plant and animal diversity. To reflect that suitability of grasslands for biodiversity strongly depends on their state, we apply the term High Nature Value grassland to those natural grasslands that are not degraded (in good state) and those secondary grasslands that are not intensified (semi-natural). The situation in a variety of countries where grasslands are evolving under the influence of global climate change is also considered. Case studies are presented on Southern Africa, Eastern Africa, India, China, South America, North America and Australia. The concluding chapter examines a set of themes arising from the chapters that make up the bulk of this book. The following provide a focus: recent history of grassland biomes – brief recap of current thinking and recent trends with special reference to dry grasslands in the Palearctic regions; the current status of grasslands and germplasm resources (biodiversity) – an overview; management systems that ensure sustainability; how to recover degraded grasslands; socio-economic issues and considerations in grassland management; the impacts of environmental problems in grasslands such as future climate change and intensification and the problems/prospects facing pastoralists and other grassland-based livestock producers.

Book Description
This book contains 28 chapters with emphasis on the interactive nature of the relationships between the soil, plant, animal and environmental components of grassland systems, both natural and managed. It analyses the present knowledge and the future trends of research for combining the classical view of grasslands, as a resource for secure feeding of an increasing human population, with the more recent perspective of the contribution of grasslands to the mitigation of environmental impacts and biodiversity erosion as consequences of human society activities. The chapters are organized within five sections dealing with the different functions and the main ecosystem services expected from grasslands: (i) domestic herbivore feeding and animal production; (ii) the regulation of biogeochemical cycles and its consequences for the environment; (iii) dynamics of biodiversity hosted by grasslands; (iv) integration of grasslands within sustainable animal production systems; and (v) interactions of grassland areas with other land use systems at the landscape level.

Book Description
Ecotones are dynamic over-lapping boundary areas where major terrestrial biomes meet. As past studies have shown, and as the chapters in this book will illustrate, their structure, size, and scope have changed considerably over the millennia, expanding and shrinking as climate and/or other driving conditions, also changed. Today, however, many of them are changing at a rate not seen for a long time, perhaps largely due to climate change and other human-induced factors. Indeed ecotones are more sensitive to climate change than the biomes on either side, and thus may serve as critical early indicators of future climate change. As ecotones change, they also redefine the limits of the biomes on either side by altering their distributions of species because, in addition to their own endemic species, any ecotone will also have species from both adjoining biomes. Consequently, they may also be places of high levels of species interaction, serving as active evolutionary laboratories, which generate new species that then migrate back into adjacent biomes. Ecotones Between Forest and Grassland explores how these ecotones have changed in the past, how they are changing today, and how they are likely to change in the future. The book includes chapters from around the world with a special focus on South American and Neotropical ecotones.

Book Description
Invertebrates perform such vital roles in global ecosystems—and so strongly influence human wellbeing—that biologist E.O. Wilson was prompted to describe them as “little things that run the world.” As they are such powerful shapers of the world around us, their response to global climate change is also pivotal in meeting myriad challenges looming on the horizon—everything from food security and biodiversity to human disease control. This book presents a comprehensive overview of the latest scientific knowledge and contemporary theory relating to global climate change and terrestrial invertebrates. Featuring contributions from top international experts, this book explores how changes to invertebrate populations will affect human decision making processes across a number of crucial issues, including agriculture, disease control, conservation planning, and resource allocation. Topics covered include methodologies and approaches to predict invertebrate responses, outcomes for disease vectors and ecosystem service providers, underlying mechanisms for community level responses to global climate change, evolutionary consequences and likely effects on interactions among organisms, and many more. Timely and thought-provoking, Global Climate Change and Terrestrial Invertebrates offers illuminating insights into the profound influence the simplest of organisms may have on the very future of our fragile world.

Book Description
"This highly synthetic and scholarly work brings together new and important scientific contributions by leading experts on a rich diversity of topics concerning the history, ecology, and conservation of California's endangered grasslands. The editors and authors have succeeded admirably in drawing from a great wealth of recent research to produce a widely accessible and compelling, state-of-the-art treatment of this fascinating subject. Anyone interested in Californian biodiversity or grassland ecosystems in general will find this book to be an invaluable resource and a major inspiration for further research, management, and restoration efforts."—Bruce G. Baldwin, W. L. Jepson Professor and Curator, UC Berkeley "Grasses and grasslands are among the most important elements of the California landscape. This is their book, embodying the kind of integrated view needed for all ecological communities in California. Approaches ranging across an incredibly broad spectrum -- paleontology and human history; basic science and practical management techniques; systematics, community ecology, physiology, and genetics; physical factors such as water, soil nutrients, atmospherics, and fire; biological factors such as competition, symbiosis, and grazing -- are nicely tied together due to careful editorial work. This is an indispensable reference for everyone interested in the California environment."—Brent Mishler, Director of the University & Jepson Herbaria and Professor of Integrative Biology, UC Berkeley "The structure and function of California grasslands have intrigued ecologists for decades. The editors of this volume have assembled a comprehensive set of reviews by a group of outstanding authors on the natural history, structure, management, and restoration of this economically and ecologically important ecosystem."—Scott L. Collins, Professor of Biology, University of New Mexico

Book Description
The aim of this book is to describe what is currently occurring in the Mongolian grasslands, to analyze how various factors creating environmental problems interact, and to suggest solutions for sustainable management of the grasslands. The book has three parts. Part I is an introduction, explaining the key concept of an ecosystem network and providing background information on the general features of Mongolian nomadic pastoralism as well as distribution of vegetation in Mongolian grasslands. Part II describes the effects of natural environmental factors and nomadic activities on grassland conditions. Water dynamics that maintain the grassland system are analyzed in a steppe region with shrubs and in a forest-steppe region with trees. Part III describes the effects of economic and social factors on land-use and the livelihood of herders. As nomadic people moved closer to large cities for economic advantage in the 1990s, degradation of pastures by overgrazing resulted. Finally, the impacts of global warming and globalization on the Mongolian society and ecosystem are examined. This book analyzes environmental problems in Mongolian grasslands, but the contents contribute to consideration of environmental problems and sustainable pasture use in grassland areas worldwide.

Book Description
Transformative Strategies is based around the idea that strategic thinking is critical for organizational success in today’s environment. The financial crisis, continuing economic uncertainty, digitalization, environmental issues, and social issues involved in globalization present strategic problems for enterprises. Unlike other textbooks that take a standard solutions-based approach, Transformative Strategies provides readers with a way to develop strategies that fit their own complex situations and shows how models may be applied in different ways to different problems. Each of the four key elements affecting the business environment (globalization, disruption, collaboration, and responsibility) are addressed as a set of tensions in eight areas: global competition, business model innovation, digital strategizing, business eco-systems, corporate social responsibility, top management teams, and trans-cultural leadership in a globalized world. This tension-based pedagogy enables readers to shift from dichotomized thinking (such as exploring or exploiting) to transformative thinking (such as exploring and exploiting; exploring through exploiting) and readers are challenged to solve real problems that companies face, encouraging them to acknowledge the broader context in which organizations operate and to analyze the problem from multiple perspectives. Each chapter is structured to aid engagement and discussion, including a discussion of the tension tied to the chapter’s topic, learning objectives, theoretical frameworks, real life case studies, exercises and reflective questions. A highly practical book that encourages readers to develop solutions that fit their own complex problems, it will be particularly suitable for those studying strategic management as part of an MBA, MA or MSc in Management, as well as those in executive education. It will also appeal to all those interested in learning how to lead and transform organizations towards impact, purpose and relevance. Online resources include discussions of the case studies, supplementary problems for class discussion, and an instructors’ manual outlining the pedagogical approach.
