The mystique of the rainforest has captured the imaginations of generations of young people, explorers, authors, and biologists. It is a delicate ecosystem whose myriad sounds and smells, whose vibrancy of life, is balanced by constant cycles of death and decay. It is a place of fierce competition where unusual partnerships are forged and creative survival strategies are the norm. In this book, you will meet the scientific pioneers who first attempted to quantify and understand the vast diversity of these tropical forests, as well as their successors, who utilize modern tools and technologies to dissect the chemical nature of rainforest interactions.

This book provides a general background on biodiversity and the study of chemical ecology before moving into specific chemical examples of insect defenses and microbial communication. It finishes with first-hand accounts of the trials and tribulations of a canopy biology pioneer and a rainforest research novice, while assessing the state of modern tropical research, its importance to humanity, and the ecological, political, and ethical issues that need to be tackled in order to move the field forward.

Desiccation tolerance was essential when plants first began to conquer land, roughly 400 million years ago. While most desiccation-tolerant plants belong to basal phylogenetic taxa, this capacity has also evolved among some vascular plant species.

In this volume renowned experts treat plant desiccation tolerance at the organismic as well as at the cellular level. The diversity of ecophysiological adaptations and acclimations of cyanobacteria, eukaryotic algae, mosses, and lichens is addressed in several chapters. The particular problems of vascular plants during dehydration/rehydration cycles resulting not only from their hydraulic architectures, but also from severe secondary stresses associated with the desiccated state are discussed. Based on the treatment of desiccation tolerance at the organismic level, a second section of the book is devoted to the cell biological level. It delineates the general concepts of functional genomics, epigenetics, genetics, molecular biology and the sensing and signalling networks of systems biology involved in dehydration/rehydration cycles.

This book provides an invaluable compilation of current knowledge, which is a prerequisite for a better understanding of plant desiccation tolerance in natural as well as agro- and forest ecosystems where water is one of the most essential resources.

This book integrates the latest global developments in forestry science and practice and their relevance for the sustainable management of tropical forests. The influence of social dimensions on the development of silvicultural concepts is another spotlight. Ecology and silvicultural options form all tropical continents, and forest formations from dry to moist forests and from lowland to mountain forests are covered. Review chapters which guide readers through this complex subject integrate numerous illustrative and quantitative case studies by experts from all over the world. On the basis of a cross-sectional evaluation of the case studies presented, the authors put forward possible silvicultural contributions towards sustainability in a changing world. The book is addressed to a broad readership from forestry and environmental disciplines.

Includes our current knowledge of the invasion or encroachment and cause of population growth and spread of some dry land, arid zone woody legumes. Community structure, population growth, and competition of these woody legumes will also be examined. These species and ecosystems are both extensive and dynamic. They occur worldwide, but mainly in the arid zones of the tropics and sub-tropics. The cause of the growth and spread of these species and communities has long been claimed to be caused by distal factors rather than proximal ones. However, these species appear to be influenced and perhaps controlled by anthropogenic factors, specifically grazing and fire or lack of fire. Their overall worldwide distribution has probably changed little in the recent past, but their populations have expanded into grasslands and their density has increased in many places. Some associated communities have shown dramatic changes in response to recent large-scale droughts and the loss of most of the dominant overstory species. However, changes in the woody legume communities and their species are generally unknown.

In this volume the dynamic patterns of human density and distribution are examined in relation to the viability of native species and the integrity of their habitats. Social, biological, and earth scientists describe their models, outline their conclusions from field studies, and review the contributions of other scientists whose work is essential to this field. The book starts with general theories and broad empirical relationships that help explain dramatic changes in the patterns of the occurrence of species, changes that have developed in parallel with human population growth, migration and settlement. In the following chapters specific biomes and ecosystems are highlighted as the context for human interactions with other species. A discussion of the key themes and findings covered rounds out the volume. All in all, the work presents our species, "Homo sapiens," as what we truly have been and will likely remain an influential, and often the most influential, constituent in nearly every major ecosystem on Earth."

When managers and ecologists need to make decisions about the environment, they use models to simulate the dynamic systems that interest them. All management decisions affect certain landscapes over time, and those landscapes are composed of intricate webs of dynamic processes that need to be considered in relation to each other. With widespread use of Geographic Information Systems (GIS), there is a growing need for complex models corporating an increasing amount of data. The open-source Spatial Modeling Environment (SME) was developed to build upon common modeling software, such as STELLA (R), and Powersim (R), among others, to create, run, analyze, and present spatial models of ecosystems, watersheds, populations, and landscapes. In this book, the creators of the Spatial Modeling Environment discuss and illustrate the uses of SME as a modeling tool for all kinds of complex spatial systems. The authors demonstrate the entire process of spatial modeling, beginning with the conceptual design, continuing through formal implementation and analysis, and finally with the interpretation and presentation of the results.A variety of applications and case studies address particular types of ecological and management problems and help to identify potential problems for modelers. Researchers and students interested in spatial modeling will learn how to simulate the complex dynamics of landscapes. Managers and decision makers will acquire tools for predicting changes in landscapes while learning about both the possibilities and the limitations of simulation models.

Having been the fourth largest lake on the globe roughly 50 years ago, today the Aral Sea no longer exists. Human activities caused its desiccation and the formation of a huge new desert, the Aralkum, which can be regarded as one of the greatest ecological catastrophes and - at the same time - the largest primary succession experiment of mankind.

This volume brings together the results of international and interdisciplinary long-term studies on the new desert ecosystem and is divided into four main sections. The first section provides an overview of the physical characteristics of the area and covers geological, pedological, geomorphological and climatological aspects and their dynamics, especially dust-storm dynamics. The second focuses on the biotic aspects and highlights the spatial and temporal patterns of the flora and fauna. In the third section studies and projects aiming to combat desertification by phytomelioration and to develop strategies for the conservation of biodiversity are presented. The book is rounded off with a section providing a synthesis and conclusions.

Plants are sessile, highly sensitive organisms that actively compete for environmental resources both above and below the ground. They assess their surroundings, estimate how much energy they need for particular goals, and then realise the optimum variant. They take measures to control certain environmental resources. They perceive themselves and can distinguish between 'self' and 'non-self'. They process and evaluate information and then modify their behaviour accordingly. These highly diverse competences are made possible by parallel sign(alling)-mediated communication processes within the plant body (intraorganismic), between the same, related and different species (interorganismic), and between plants and non-plant organisms (transorganismic). Intraorganismic communication involves sign-mediated interactions within cells (intracellular) and between cells (intercellular). This is crucial in coordinating growth and development, shape and dynamics. Such communication must function both on the local level and between widely separated plant parts. This allows plants to coordinate appropriate response behaviours in a differentiated manner, depending on their current developmental status and physiological influences. Lastly, this volume documents how plant ecosphere inhabitants communicate with each other to coordinate their behavioural patterns, as well as the role of viruses in these highly dynamic interactional networks.

This important and insightful book provides, for the first time, a broad presentation of ongoing research into public participation in landscape conservation, management and planning, following the 2000 European Landscape Convention which came into force in 2004. The book examines both the theory of participation and what lessons can be learnt from specific European examples. It explores in what manner and to what extent the provisions for participation in the European Landscape Convention have been followed up and implemented. It also presents and compares different experiences of participation in selected countries from northern, southern, eastern and western Europe, and provides a critical examination of public participation in practice. However, while the book's focus is necessarily on Europe, many of the conclusions drawn are of global relevance. The book provides a valuable reference for researchers and advanced students in landscape policies and management, as well as for professionals and others interested in land-use planning and environmental management.

Global warming is expected to change fire regimes, likely increasing the severity and extent of wildfires in many ecosystems around the world. What will be the landscape-scale effects of these altered fire regimes? Within what theoretical contexts can we accurately assess these effects? We explore the possible effects of altered fire regimes on landscape patch dynamics, dominant species (tree, shrub, or herbaceous) and succession, sensitive and invasive plant and animal species and communities, and ecosystem function. Ultimately, we must consider the human dimension: what are the policy and management implications of increased fire disturbance, and what are the implications for human communities?

Millions of trees live and grow all around us, and we all recognize the vital role they play in the world's ecosystems. Publicity campaigns exhort us to plant yet more. Yet until recently comparatively little was known about the root causes of the physical changes that attend their growth. Since trees typically increase in size by three to four orders of magnitude in their journey to maturity, this gap in our knowledge has been a crucial issue to address. Here at last is a synthesis of the current state of our knowledge about both the causes and consequences of ontogenetic changes in key features of tree structure and function. During their ontogeny, trees undergo numerous changes in their physiological function, the structure and mechanical properties of their wood, and overall architecture and allometry. This book examines the central interplay between these changes and tree size and age. It also explores the impact these changes can have, at the level of the individual tree, on the emerging characteristics of forest ecosystems at various stages of their development. The analysis offers an explanation for the importance of discriminating between the varied physical properties arising from the nexus of size and age, as well as highlighting the implications these ontogenetic changes have for commercial forestry and climate change. This important and timely summation of our knowledge base in this area, written by highly respected researchers, will be of huge interest, not only to researchers, but also to forest managers and silviculturists.

A multiplicity of biotrophic micro-organisms interact with plants in nature, forming symbiotic relationships that range from mutualism to antagonism. Microorganisms that have adopted biotrophy as a lifestyle are able to colonize the plant and often to cross the plant cell boundaries by forming intracellular structures that are the site of nutrient uptake/exchange. To establish themselves within plant tissues, both mutualistic and pathogenic biotrophs need to overcome the plant defense response through an exchange of molecular signals. Our knowledge of the nature of these signals and their function in the interaction has rapidly increased over the last few years. This volume focuses on the genetic, molecular and cellular components involved in the communication between partners of well-known symbioses, but also reports on the advances for less studied systems.

Natural and agro-ecosystems are frequently exposed to natural or synthetic substances, which, while they have no direct nutritional value or significance in metabolism, may negatively affect plant functioning. These, xenobiotics, may originate from both natural (fires, volcano eruptions, soil or rock erosion, biodegradation) and anthropogenic (air and soil pollution, herbicides) sources. And, while affected plants have only a limited number of possibilities for avoiding accumulation of these compounds, they do exhibit several enzymatic reactions for detoxification including oxidation, reduction, hydrolysis and conjugation reactions. In agro-ecosystems in particular these mechanisms have great significance in relation to herbicide detoxification and tolerance. In this volume an international group of experts present an overview of the nature and distribution of organic xenobiotics, including their uptake, effects on plant functioning and detoxification mechanisms. The particular significance of glutathione S-transferases in bio-indication and bio-monitoring, and in the detoxification of volatile organic air pollutants and herbicides is evaluated, and their potential significance in phytoremediation and bioaccumulation will be discussed. This volume will be of interest to a wide audience, from graduate students to senior researchers in a wide range of disciplines including plant ecology, plant biochemistry, agriculture and environmental management. It will also be of practical interest to environmentalists, policy makers and resource managers.

The book reviews the literature on the ecological succession of plants on fallowed swiddens in tropical forests. Patterns of ecological succession in tropical forests are insufficiently understood, partly because results are scattered through a large number of case studies reported in academic articles. So far, no publication has attempted to bring these different case studies together to identify common patters and trends. The goal of the book is to review the different case studies, and identify common patterns of ecological succession in fallowed swiddens, as well as to pinpoint the factors that cause ecological succession in some areas to differ from those in other areas. The book is organised in four different sections: forest structure, forest diversity, species composition, and the factors that contribute to differences in forest recovery rates (the number of times the field was burned, the length of fallow period, the type of soil, and the type of forest). This book is an important contribution to tropical forestry and shifting cultivation. Deforestation and forest degradation are the largest sources of CO2, and shifting cultivation is one of the main culprits. For this (and other economic and political) reason governments attempt to curtail shifting cultivation by shortening the years the fields can be left fallow, or outright outlawing the farming practice. Yet, there is insufficient understanding of the processes of ecological succession in fallows, which raises the questions as to whether the policy fulfils its objectives. "

It is an honor and pleasure for me to write the foreword of this book comprising the of Forest Resources for proceedings of the Fourth Symposium on the Improvement Recyclable Forest Products. The symposium was organized by Dr. Toshihiro Ona, Associate Professor at the Graduate School of Bioresource and Bioenvironmental Sciences, Kyushu University, Japan, as part of the "Development of Forest Resources with High Performance for Paper Recycling" research project. This was supported by the Core Research for Evolutional Science and Technology (CREST) team at the Japan Science and Technology Agency Foundation (lST) and by Kyushu University. As a colleague of Dr. Ona, I commend his efforts in organizing the symposium and editing this book. In the forest, there is a multitude of resources, including trees, herbal plants, fruits, fungi, mammals, birds, insects, fishes, reptiles, water, landscapes, and tourist attractions. Nowadays, even the environment is regarded as a kind of forest resource. These resources can provide a diversity of forest products, such as timber for buildings, pulp and paper, charcoal, herbal medicines, wild vegetables, animal protein, edible mushrooms, and nonwoody fibers. From these resources, major forest products are produced using various species of trees. For example, softwood is suitable as building material, while hardwood is suitable for furniture production; pulp and paper are produced from both softwood and hardwood. Therefore, forest locations and forest management methods should vary according to the tree species used for production of different forest products.

This is the first volume to be published under a new series agreement for Recent Advances in Phytochemistry. It provides a good picture of the state of plant (bio) chemistry research in North America, which is indicative of the state of the field worldwide.

This new book takes us through a journey from early life to modern agriculture. The thirty eight authors present current studies on the interrelation of plants-animals. This topic has always fascinated man, as evidenced even by the first chapters of Genesis. The world of aqueous and terrestrial fauna appeared on early earth only after the flora covered the areas with the green pigmentation. Almost all life depends upon sunlight via the photosynthesis of the botanical world. We read abut the harnessing of bee pollination of crops to make it an essential component of modern agriculture endeavor. Some plants seduce insects for pollination by their appearance (e.g., disguised orchids entice visitors); there is the production of sweet nectar as a bribe in flowers to attract bees, butterflies, and honey-sucking birds. A particular outstanding phenomena are the carnivorous plants that have developed trapping and digesting systems of insects and higher animals.

At Middle Woodland sites in the eastern United States, excavations have uncovered naturalistic art worked on exotic materials from points as distant Wyoming, Ontario, and the Gulf Coast, revealing a network of ritual exchange referred to as the Hopewell phenomenon. Simultaneously, Middle Woodland societies developed the earliest agricultural system in eastern North American using now-extinct native cultivars. "Mound Centers and Seed Security: A Comparative Analysis of Botanical Assemblages from Middle Woodland Sites in the Lower Illinois Valley" integrates an interpretation of these two historical trends.

Unlike most journal articles on related subjects, the volume includes a lengthy review of literature on both Hopewell studies and Middle Woodland agriculture, making it a useful resource for researchers starting out in either field. Synthesizing both original research and research reported in archaeological grey literature, "Mound Centers and Seed Security: A Comparative Analysis of Botanical Assemblages from Middle Woodland Sites in the Lower Illinois Valley" is a valuable tool for researchers and teachers alike."

Increasing awareness of the irreversible and long-lasting impacts of deterioration and pollution of soils and sediments has had an important influence on environmental policies and research in the last decade. The complexity of the soil and sediment systems and its processes cannot be tackled properly unless scientists from different disciplines work together. With this in mind, a number of multidisciplinary soil research programmes have been started in various European countries. They involve different disciplinary approaches and they aim at different fields of application: agriculture, land use and town and country planning, drinking water supply, nature management. The results that are now appearing need to be integrated in a scientifically sound and useful way. The first European Conference on Integrated Research for Soil and Sediment Protection and Remediation was intended to foster this. The volume contains the edited and selected proceedings of this Conference.

The United Nations Conference on the Environment and Development (UNCED), held in Rio de Janeiro in 1992, spawned a multitude of pro grammes aimed at assessing, managing and conserving the earth's biological diversity. One important issue addressed at the conference was the mountain environment. A specific feature of high mountains is the so-called alpine zone, i. e. the treeless regions at the uppermost reaches. Though covering only a very small proportion of the land surface, the alpine zone contains a rela tively large number of plants, animals, fungi and microbes which are specifi cally adapted to cold environments. This zone contributes fundamentally to the planet's biodiversity and provides many resources for mountain dwelling as well as lowland people. However, rapid and largely man-made changes are affecting mountain ecosystems, such as soil erosion, losses of habitat and genetic diversity, and climate change, all of which have to be addressed. As stated in the European Community Biodiversity Strategy, "the global scale of biodiversity reduction or losses and the interdependence of different species and ecosystems across national borders demands concerted international action". Managing biodiversity in a rational and sustainable way needs basic knowledge on its qualitative and quantitative aspects at local, regional and global scales. This is particularly true for mountains, which are distributed throughout the world and are indeed hot spots of biodiversity in absolute terms as well as relative to the surrounding lowlands.

Japan s traditional and fragile satoyama landscape system was developed over centuries of human life on mountainous island terrain in a monsoon climate. The carefully managed coppice woodlands on the hillsides, the villages strung along the base of the hills, and the carefully tended paddy fields of rural Japan made possible the sustainable interaction of nature and humans. Radical changes in the middle of the twentieth century led to the abandonment of satoyama landscapes which now are being rediscovered. There is a new realization that these woodlands still play a vital role in the management of the Japanese landscape and a new determination to manage them for the future. This multifaceted book explores the history, nature, biodiversity, current conservation measures, and future uses of satoyama. The information presented here will be of interest in all parts of the world where patterns of sustainable development are being sought.

Piper is an economically and ecologically important genus of plant that includes a fascinating array of species for studying natural history, natural products chemistry, community ecology, and evolutionary biology. The diversification of this taxon is unique and of great importance in understanding the evolution of plants. The diversity and ecological relevance of this genus makes it an obvious candidate for ecological and evolutionary studies, but surprisingly, most research on Piper spp. to-date has focused on the more economically important plants P. nigrum (black pepper), P. methysticum (kava), and P. betle (betel leaf). While this book does address the applied techniques of studying Piper, its focus is more on Piper in its natural setting. Piper: A Model Genus for Studies of Phytochemistry, Ecology, and Evolution synthesizes existing data and provides an outline for future investigations of the chemistry, ecology, and evolution of this taxon, while examining its key themes of Piper as a model genus for ecological and evolutionary studies, the important ecological roles of Piper species in lowland wet forests, and the evolution of distinctive Piper attributes. This volume has a place in the libraries of those studying or working in the fields of ecology, evolutionary biology, natural products chemistry, invasive species biology, pharmaceutics, and ethnobotany.

remnants of gene pools of these species. Badghyz Natural Reserve, established in 1941, became a refuge for the last existing population of the Turkmen onager (Equus hemionus onager) and a unique pistachio woodland. A new generation oflocal Turkmen scientists, many of whom were trained by the Russian researchers in the graduate schools of Moscow and Leningrad arose from the 1930s through the 1950s. The Turkmen Academy of Sciences and its journal, Proceedings (including the monthly biological series), served to record the results of diverse biological studies in the republic. While basic science in the Middle Asian republics rather gained from the Russian "colonial" influence, natural resources, in contrast, were severely damaged by the Soviet way of handling the economy and social issues. Severe environmental problems have been inherited by the now independent Turkmenistan, including overgrazed desert pastures, deforested mountains, depleted water resources, accumulated pesticides in cotton fields, declining populations of endangered species of animals and plants, and - worst of al- progressing, human-caused desertification (Kharin this volume). In order to approach a solution to these problems, scientists and officials in the republic will need the close attention and help of the international scientific community.
