not only for land use systems that depend on the regular supply of rain or irrigation water but also for the future development of natural rainforests as drought stress has been shown to a?ect tree growth and species composition in old-growth forests (Wright 1991, Walsh and Newbery 1999, Engelbrecht et al. 2007). A drought experiment conducted in a cacao agroforestry plantation showed that this plantation was surprisingly resilient to an induced drought of more than a year (Schwendenmann et al. 2009). However, droughts can have a strong impact on household incomes from agriculture, they strongly a?ect the vulnerability to poverty and thus have to be analyzed as important exogenous shocks to households, forcing them to adjust their behaviour and develop strategies to cope with these problems. The stability of rainforest margins is a critical factor in the protection of tropical rainforests (Tscharntke et al. 2007). At present, however, rainf- est margins in many parts of the tropics are far from stable, both in soc- economic and in ecological terms. For example, protected areas may attract, rather than repel, human settlement, which may be due to international donor investment in national conservation programs (Wittemeyer et al. 2008). An alternative hypothesis is that protected areas might be compromised if leakage takes place, that is, if impacts that would take place inside the restricted area are displaced to a nearby, undisturbed area (Ewers and Rodrigues 2008).

This book is the result of 14 years of collecting Entolomataceae in the native forests of Tasmania, Australia. Although initially involving only the Tasmanian residents Genevieve Gates and David Ratkowsky, who made twice- or thrice-weekly forays into the forests throughout the year, the project was subsequently joined by agaric specialist Machiel Noordeloos from the Netherlands, and by fungi photographer Michael Pilkington from the United Kingdom. The international character of the project is further evidenced by the earlier contributions of American mycologist Tim Baroni to the Tasmanian Rhodocybe species which form the basis of the chapter on the now-expanded concept of Clitopilus, and a visit of several months in 2010 by Brazilian Ph.D. candidate Fernanda Karstedt, who tested the keys to the Entoloma species. Consequently, several thousand well-annotated collections were found during this inventory and form the basis of this monographic treatment of the Entoloma and Clitopilus of Tasmania. The resulting 90 Entoloma species and 10 Clitopilus species are well documented with standardized descriptions, line drawings of fruit bodies and diagnostic microscopic characters, and, when available, with colour photographs. Thanks to the intensive search, it was possible to illustrate most species in colour. Dichotomous keys facilitate identification of the species. The species concept used is morphologically based; in several cases, however, identification to species level is supported by molecular data.

The work describes the general ecological aspects of Iran as well as West and Central Asia in the introduction. The book includes three chapters, each describing the climate, geology and soil characteristics, vegetation and forest types, site demands of the main tree species and the ecogram of them, management and socio-economic issues of three different phytogeographical regions, mainly the Hyrcanian, Irano-Turanian, and Saharo-Sindian. Each chapter contains a table for introducing the English and Botanical names of the plant species mentioned in the chapter. The information presented in this book is based on personal experiences and results of research projects of the authors, as well as experiences of other forest scientists in Iran. The references are given at the end of each chapter separately. The book contains 10 tables, 37 black and white and 55 color pictures.

Palms are monocots, Angiosperms, belonging to the family Palmae (Arecaceae), perennials having woody stems. Palmae (Arecaceae) family comprised of about six subfamilies, 200 genera and 2,700 species that are distributed all over the tropical, subtropical and Mediterranean landscape. Palms are diverse (ecologically and morphologically) group of plants. Ornamental palms are important component of landscape as well as interiorscapes. Additionally, these plants are good source of food, feed and shelter with numerous other commercial benefits. Likewise other trees and crops, landscape and field nurseries of palms are also subjected to various threats of insect pest and diseases (caused by different plant pathogens). Amongst fungal diseases leaf spots, leaf blights, Fusarium wilts, butt rots, bud rots, root rots, lethal yellowing and decline of palms are major growth constraints of palm growth. In developing countries very little attention has been paid on the etiology and management of these fungal diseases on ornamental palms. Accurate diagnosis and reliable management plan of palm fungal diseases usually requires expertise in both modern and advanced plant pathological approaches. Historically it was general belief that plant pathogens are not associated with human diseases. Since 19th century, several clinical reports are available indicating many plant pathogenic fungi (Aspergillus spp., Penicillium spp., Alternaria spp., Trichoderma spp., Fusarium spp., Curvularia spp. and Colletotrichum Spp) as novel agents of human diseases. Besides the association of fungal plant pathogens infecting ornamental palms, harbouring any of earlier mentioned or other fungal species (capable of causing certain diseases in human beings or pets) by the ornamental palms cultivation (either grown indoor or outdoor) is an important area of research to be explored and addressed thoroughly. This book will provide the deep information regarding major fungal diseases of ornamental palms, their symptoms, disease identification, and etiology and management strategies. This book will also provide unique knowledge regarding the ornamental palms harbouring kinds of human fungal pathogens and their practical management at domestic and commercial scale, in order to make cultivation of these plant more beneficial for humans, animals and environment.

This book provides a comprehensive, global synthesis of current knowledge on the potential and challenges associated with the multiple roles, use, management and marketing of non-timber forest products (NTFPs). There has been considerable research and policy effort surrounding NTFPs over the last two and half decades. The book explores the evolution of sentiments regarding the potential of NTFPs in promoting options for sustainable multi-purpose forest management, income generation and poverty alleviation. Based on a critical analysis of the debates and discourses it employs a systematic approach to present a balanced and realistic perspective on the benefits and challenges associated with NTFP use and management within local livelihoods and landscapes, supported with case examples from both the southern and northern hemispheres. This book covers the social, economic and ecological dimensions of NTFPs and closes with an examination of future prospects and research directions.

This volume contains a solid body of the current state of knowledge on the various themes and activities in agroforestry worldwide. It is organized into three sections: the Introduction section consists of the summaries of six keynote speeches at the 2nd World Congress of Agroforestry held in Nairobi, Kenya, in 2009; that is followed by two sections of peer-reviewed thematic chapters grouped as "Global Perspectives" (seven chapters) and "Regional Perspectives" (eleven chapters), authored by professional leaders in their respective agroforestry-related fields worldwide. A total of 130 professionals from institutions in 33 countries in both developing and the industrialized temperate regions of the world contributed to the book as chapter authors and/or reviewers. Thus, the book presents a comprehensive and authoritative account of the global picture of agroforestry today.

This is the fourth updated and revised edition of a well-received book that emphasises on fungal diversity, plant productivity and sustainability. It contains new chapters written by leading experts in the field. This book is an up-to-date overview of current progress in mycorrhiza and association with plant productivity and environmental sustainability. The result is a must hands-on guide, ideally suited for agri-biotechnology, soil biology, fungal biology including mycorrhiza and stress management, academia and researchers. The topic of this book is particularly relevant to researchers involved in mycorrhiza, especially to food security and environmental protection. Mycorrhizas are symbioses between fungi and the roots of higher plants. As more than 90% of all known species of plants have the potential to form mycorrhizal associations, the productivity and species composition and the diversity of natural ecosystems are frequently dependent upon the pre sence and activity of mycorrhizas. The biotechnological application of mycorrhizas is expected to promote the production of food while maintaining ecologically and economically sustainable production systems.

"Forests in Development: A Vital Balance," shows some of the main advances in forestry over the six years spanning between the XII World Forestry Congress in Canada and the XIII WFC held in Buenos Aires. The book covers most of the themes of the XIII WFC, from biodiversity through production, policies, environmental services, and economic aspects, linked by sustainability. It provides a comprehensive view of forestry today, conveying its different aspects through one solid piece addressed by authors whose work denotes a concept of sustainable forest management which is not so much a puzzle laboriously put together as a many-faced unity, steered to achieve ultimately a better quality of living for present and future generations.

This book provides current knowledge about tropical rain forest genetics and its implications for the profitable and sustainable management of forest resources in Southeast Asia. Each chapter covers a major topic in the evolutionary biology of tropical rain forest trees and how management systems interact with these natural dynamics. Authors provide an up-to-date and insightful review of important scientific findings and conclude with practical recommendations for the modern forester in Southeast Asia. Several chapters provide compelling discussions about commonly neglected aspects of tropical forestry, including the impact of historical dynamics of climate change, anthropogenic threats to genetic viability, and the important role of wildlife in maintaining genetic diversity. These discussions will promote a deeper appreciation of not only the economic value of forests, but also their mystery and intangible values. The silvicultural industry in Southeast Asia is a major contributor to the regional economy but the connection between scientific research and the application and development of policy could be improved upon. This book will help bridge that gap.

This book will prove beneficial reading for forestry students, professional forest managers, and policy makers, who do not have technical training in genetics. It is also intended for non-specialists who are involved in the tropical timber industry, from the local forest manager to the international timber purchasing agent.

There is a strong movement towards uneven-aged forest management based on the idea that such stands increase or at least maintain soil fertility, increase biodiversity, and improve stand resilience. This shift in forest management practice renders existing yield tables increasingly unreliable. Among potential alternatives are tree growth models, because they predict the growth of each tree within a forest stand. This book summarizes three years of work related to the topic, carried out as a joint effort of leading tree growth modellers across Europe together with forest companies. By means of nine specific examples it demonstrates the problem-solving potential of tree growth modeling theory as required by various end-user groups.

Biological nitrogen fixation (BNF) - the conversion of molecular nitrogen into ammonia - is one of the most important reactions in ecology and agriculture. It is performed exclusively by microbes (prokaryotes) that live in symbiosis with plants. This book summarizes the latest research on this reaction, the participating microbes and the genetics of how their relevant genes could be transferred into the plants. In the light of a more sustainable and less ecologically damaging agriculture, this is becoming an increasingly pressing issue.

This book mainly focuses on ecological approaches for preventing and controlling non-point source (NPS) pollution on the basis of forestry measures. In addition to the effects of ecological control, it introduces readers to the characteristics of NPS pollution in Taihu Lake watershed, water eutrophication evaluation methods, and potential countermeasures. Given the crucial role of surface runoff and soil erosion in producing water pollution, the book presents forestry measures to combat them, such as the creation of public welfare forests, urban forestry, planting techniques for hedgerows on slope land, the establishment of shelter belts, nitrogen and phosphorus absorption by hydrophytes, and sustainable management for wetlands. Moreover, the results are supplemented by a wealth of numerical calculations, tables, figures and photographs. The book offers a valuable guide for researchers, educators and professionals working in the areas of water environment, water security and ecological construction. Prof. Jianfeng Zhang works at the Institute of Subtropical Forestry, Chinese Academy of Forestry, Fuyang, China.

This is a handbook on the subject of crop pests. Including 288 colour photographs, the book contains information which has been edited and updated from the series of advisory leaflets issued by the Ministry of Agriculture, Fisheries and Food (MAFF) which have been a widely acknowledged source of valuable information for many years. Much of the information, which has been revised by entomologists of the Agricultural Development Advisory Service (ADAS), should be of interest in other countries of Northern Europe and throughout temperate regions of the world. The book contains descriptions of the pests, their life histories, the damage they cause, their natural enemies and the strategies for control. The demand for the continued availability of the wealth of knowledge and practical experience originally incorporated into the MAFF leaflets has prompted the publication of this book. This publication should be a useful handbook for all those involved with applied entomology and crop protection, particularly agricultural and horticultural students, crop consultants and advisers, those working in the agrochemical industry and proficient farmers, growers and entomologists.

Van Laar and Akca's popular text book, Forest Mensuration, was first published in 1997. Like that first edition, this modern update is based on extensive research, teaching and practical experience in both Europe, and the tropics and subtropics. However, it has also been extensively revised, and now includes chapters on remote sensing and the application of aerial photographs and satellite imagery. The book assumes no advanced knowledge of statistical methods, and combines practical techniques with important historical and disciplinary context. The result is a strong balance between a handbook and a valuable reference.

This book is primarily a general text covering the whole sweep of the forest industries. The over-riding emphasis is on a clear, simple interpretation of the underlying science, demonstrating how such principles apply to processing operations. The book starts by considering the broad question what is wood? by looking at the biology, chemistry and physics of wood structure (first 4 chapters). This sets the scene. Next key chapters examine wood quality - explaining how and why wood quality can be so variable and implications for processing. Finally, in a series of chapters, various industrial processes are reviewed and interpreted. The 2nd Edition is a total revision. A few chapters remain relatively unchanged (no change for the sake of change). Many have been totally rewritten. All chapters have been written by specialists, but the presentation targets a generalist audience.

For the first time, this opportune book provides a comprehensive treatment of the many innovative, non-timber bioproducts that may be derived from Canada 's vast forests, including their potential economic, social and environmental impacts. It also offers a balanced discussion of the technological, policy and regulatory issues surrounding the emerging global bioeconomy. This book will not only be of interest to Canadian forestry professionals and entrepreneurs, but also to those interested in the contribution of forestry to the bioeconomy worldwide.

Agroforestry, the word coined in early seventies, has made its place in all the developed and the developing countries of the world and is now recognized as an important approach to ensuring food security and rebuilding resilient rural environments. India has been an all-time leader in agroforestry. The South and Southeast Asia region comprising India is often described as the cradle of agroforestry. Almost all forms of agroforestry systems exist across India in ecozones ranging from humid tropical lowlands to high-altitude and temperate biomes, and perhumid rainforest zones to parched drylands. The country ranks foremost among the community of nations not only in terms of this enormous diversity and long tradition of the practice of agroforestry, but also in fostering scientific developments in the subject. Agroforestry applies to private agricultural and forest lands and communities that also include highly erodible, flood-prone, economically marginal and environmentally sensitive lands. The typical situation is agricultural, where trees are added to create desired benefits. Agroforestry allows for the diversification of farm activities and makes better use of environmental resources. Owing to an increase in the population of human and cattle, there is increasing demand of food as well as fodder, particularly in developing countries like India. So far, there is no policy that deals with specifics in agroforestry in India. But, the Indian Council of Agricultural Research has been discussing on the scope of having a National Agroforestry Policy in appropriate platforms. However, evolving a policy requires good and reliable datasets from different corners of the country on the subject matter. This synthesis volume containing 13 chapters is an attempt to collate available information in a classified manner into different system ecologies, problems and solutions, and converging them into a policy support.

This book provides a comprehensive overview of the benefits of biofertilizers as an alternative to chemical fertilizers and pesticides. Agricultural production has increased massively over the last century due to increased use of chemical fertilizers and pesticides, but these gains have come at a price. The chemicals are not only expensive; they also reduce microbial activity in agricultural soils and accumulate in the food chain, with potentially harmful effects for humans. Accordingly, it is high time to explore alternatives and to find solutions to overcome our increasing dependence on these chemicals. Biofertilizers, which consist of plant remains, organic matter and microorganisms, might offer an alternative. They are natural, organic, biodegradable, eco-friendly and cost-effective. Further, the microbes present in the biofertilizers are important, because they produce nutrients required for plant growth (e.g., nitrogen, phosphorus, potassium), as well as substances essential for plant growth and development (e.g., auxins and cytokinins). Biofertilizers also improve the physical properties, fertility and productivity of soil, reducing the need for chemical fertilizers while maintaining high crop yield. This makes biofertilizers a powerful tool for sustainable agriculture and a sustainable environment. The book covers the latest research on biofertilizers, ranging from beneficial fungal, bacterial and algal inoculants; to microbes for bioremediation, wastewater treatment; and recycling of biodegradable municipal, agricultural and industrial waste; as well as biocontrol agents and bio-pesticides. As such, it offers a valuable resource for researchers, academics and students in the broad fields of microbiology and agriculture.

Latin America is a megadiverse territory hosting several hotspots of plant diversity and many types of forest biomes, ecosystems and climate types, from tropical rainforest to semi-arid woodlands. This combination of diverse forests and climates generates multiple responses to ecological changes affecting the structure and functioning of forest ecosystems. Recently, there have been major efforts to improve our understanding of such impacts on ecosystems processes. However, there is a dearth of studies focused on Latin-American forest ecosystems that could provide novel insights into the patterns and mechanisms of ecological processes in response to environmental stress. The abundance of "New World" tree species with dendrochronological potential constitutes an ideal opportunity to improve the ecological state of knowledge regarding these diverse forest types, which are often threatened by several impacts such as logging or conversion to agricultural lands. Thus, detailed information on the dendroecology of these species will improve our understanding of forests in the face of global change. Accordingly, this book identifies numerous relevant ecological processes and scales, ranging from tree species to populations and communities, and from both dendrochronological and dendroecological perspectives. It offers a valuable reference guide for the exploration of long-term ecological interactions between trees and their environmental conditions, and will foster further research and international projects on the continent and elsewhere.

Natural resource management by rural citizens in tropical regions is crucial both to the conservation of biodiversity and ecosystem processes, but also to the the well-being and food security of the people that live there. This situation is especially acute in Africa where conflicts between habitat destruction and utilization can arise in areas which are important not only for biodiversity but for the long-term maintenance of ecosystems on which the people ultimately rely. There can also be conflicts between outside specialists and the indigenous knowledge of local communities. A holistic approach involving local peoples in management of their natural resources is therefore essential. A range of approaches to the problem is explored here in relation to natural resource management to local development and livelihoods, and the multi-functional nature of land-use. Major topics debated are the dichotomy between strictly protected areas and ones including human activity, people-centred rather than legally enforced conservation, market forces, and the interrelationships between agriculture and conservation. The book has 12 chapters, prepared by researchers actively involved in community aspects of natural resource management in Africa, and is based on an international workshop held in Niamey, Niger, in 2008. It will be of interest to all involved in the community approach to biodiversity conservation in less developed countries generally and not only in Africa as many of the issues addressed are pertinent globally.
