Book excerpt: Proposes that the overall outcome of plant interactions along a temporal gradient of resource availability changes from positive during interpulses to negative during pulses. Examines negative interactions between 4 co-dominant chenopod scrubs in arid Acacia papyrocarpa woodlands. Negative interactions were more intense when conditions were least productive. Positive interactions between seedlings also changed over time, depending on the facilitation mechanism. Plant interactions seem to be most intense at the beginning of interpulses when plants are competing for diminishing water, or survivorship is enhanced in the favorable microsites provided by other plants. Later in the interpulse, interactions become less intense as conditions become more stressful and therefore survivorship and growth are affected more by abiotic conditions than plant interactions.

Book excerpt: Agroforestry (AF) is a dynamic, ecologically based, natural resources management system that, by integrating trees on farms, ranches, and in other landscapes, diversifies and increases production and promotes social, economic, and environmental benefits for land users. Further, it is receiving increasing attention as a sustainable land-management option worldwide because of its ecological, economic, and social attributes. Advances have been achieved by building on past research accomplishments and expanding AF’s stakeholder base, which now includes private/public partnerships, communities, ecologists, farmers, indigenous peoples, and policymakers in both temperate and tropical countries. AF has now been recognized as a valuable problem-solving approach to ensuring food security and rebuilding resilient rural environments. Recent studies have shown that more than 1 billion hectares of agricultural land have more than 10% tree cover. Of this area, 160 million hectares have more than 50% tree cover. Agricultural ecosystems can be further improved through AF to achieve environmental restoration, greater farm productivity, and key ecological services, including climate change mitigation and adaptation for improved rural livelihood. In fact, it is largely considered synonymous with climate smart agriculture and a remedy for many modern environmental challenges. Consequently, AF’s knowledge base is being expanded at a rapid rate, as illustrated by the increasing number and quality of scientific publications on various forms and different aspects of AF. This book offers state-of-the-art information on the fundamental concepts and history of AF and its evolution as a science, presenting a wealth of advanced research results and evaluations relating to different aspects of AF. Accordingly, it will be useful for a broad readership, including students, foresters, farmers, local communities, indigenous peoples, civil society institutions, media, policymakers and the general public.

Available in PDF, EPUB and Kindle. Book excerpt: Community ecology has undergone a transformation in recent years, from a discipline largely focused on processes occurring within a local area to a discipline encompassing a much richer domain of study, including the linkages between communities separated in space (metacommunity dynamics), niche and neutral theory, the interplay between ecology and evolution (eco-evolutionary dynamics), and the influence of historical and regional processes in shaping patterns of biodiversity. To fully understand these new developments, however, students continue to need a strong foundation in the study of species interactions and how these interactions are assembled into food webs and other ecological networks. This new edition fulfils the book's original aims, both as a much-needed up-to-date and accessible introduction to modern community ecology, and in identifying the important questions that are yet to be answered. This research-driven textbook introduces state-of-the-art community ecology to a new generation of students, adopting reasoned and balanced perspectives on as-yet-unresolved issues. Community Ecology is suitable for advanced undergraduates, graduate students, and researchers seeking a broad, up-to-date coverage of ecological concepts at the community level.

Book excerpt: Understanding deserts and drylands is essential, as arid landscapes cover >40% of the Earth and are home to two billion people. Today's problematic environment-human interaction needs contemporary knowledge to address dryland complexity. Physical dimensions in arid zones-land systems, climate and hazards, ecology-are linked with social processes that directly impact drylands, such as land management, livelihoods, and development. The challenges require integrated research that identifies systemic drivers across global arid regions. Measurement and monitoring, field investigation, remote sensing, and data analysis are effective tools to investigate natural dynamics. Equally, inquiry into how policy and practice affect landscape sustainability is key to mitigating detrimental activity in deserts. Relations between socio-economic forces and degradation, agro-pastoral rangeland use, drought and disaster and resource extraction reflect land interactions. Contemporary themes of food security, conflict, and conservation are interlinked in arid environments. This book unifies desert science, arid environments, and dryland development. The chapters identify land dynamics, address system risks and delineate human functions through original research in arid zones. Mixed methodologies highlight the vital links between social and environmental science in global deserts. The book engages with today's topical themes and presents novel analyses of arid land systems and societies.

This book was released on 2012-12-06 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a quantitative analysis of the role of woody plants in semi-arid regions, for the aSSessment of their benefits in agrosylvopastoralland-use systems with productive and sus tainability objectives. The insights presented and conclusions drawn allow the additional benefits of woody plants for specific climatic and physical site conditions and land-use systems to be estimated. The Sahel and Sudan zones in West Africa, on which the book focusses, represent resource-poor conditions, whose ecological dynamics have been relatively well studied. The role of woody plants in this region, as assessed in this book, is extrapolated to other semi-arid regions, leading to general conclusions on agroforestry's potential as an option for sustainable land use in semi-arid regions. The origins of this book go back to 1982, when the Club du Sahel requested that available data on woody plants in the Sahel region be synthesised, to provide basic information to enable better attention to be given to woody plants in rural development programmes. We are grateful to the Club du Sahel for this challenge. Various people contributed to studies used in this book. The preliminary inventory of the data available was made by Frits Ohler; later his work was continued by Franciska Dekker.

Book excerpt: This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.

Available in PDF, EPUB and Kindle. Book excerpt: This advanced textbook explores the intriguing flora and plant ecology of the Middle East, framed by a changing desert landscape, global climate change, and the arc of human history. This vast region has been largely under-recognized, under-studied, and certainly under-published, due in part to the challenges posed to research by political disputes and human conflict, and a treatise on the subject is now timely. The book integrates Middle Eastern plant geography and its major drivers (geo-tectonics, seed and fruit dispersal, plant functional types, etc.) with the principles of plant ecology. The authors include the many specialized adaptations to desert and dryland ecosystems including succulence, water-conserving photosynthesis, and a remarkable range of other life history strategies. They explore the formation of 'climate relicts', and describe the long history of domestication in the region together with the many reciprocal effects of agriculture on plant ecology. The book concludes by discussing conservation in the region, highlighting five regional biodiversity hotspots where the challenges of desertification, habitat loss, and other threats to plant biodiversity are particularly acute. Plant Ecology in the Middle East is a timely synthesis of the field, setting a new baseline for future research. It will be important reading for both undergraduate and graduate students taking courses in plant ecology, evolution, systematics, biodiversity, and conservation, and will also be of interest and use to a professional audience of botanists, conservation biologists, and practitioners working in dryland ecosystems.
