Our image of plants is changing dramatically away from passive entities merely subject to environmental forces and organisms that are designed solely for the accumulation of photosynthate. Plants are revealing themselves to be dynamic and highly sensitive organisms that actively and competitively forage for limited resources, both above and below ground, organisms that accurately gauge their circumstances, use sophisticated cost-benefit analysis, and take clear actions to mitigate and control diverse environmental threats. Moreover, plants are also capable of complex recognition of self and non-self and are territorial in behavior. They are as sophisticated in behavior as animals but their potential has been masked because it operates on time scales many orders of magnitude less than those of animals. Plants are sessile organisms. As such, the only alternative to a rapidly changing environment is rapid adaptation. This book will focus on all these new and exciting aspects of plant biology.

Climate changes, particularly warming trends, have been recorded around the globe. For many countries, these changes in climate have become evident through insect epidemics (e.g., Mountain Pine Beetle epidemic in Western Canada, bark beetle in secondary spruce forests in Central Europe), water shortages and intense forest fires in the Mediterranean countries (e.g., 2005 droughts in Spain), and unusual storm activities (e.g., the 2004 South-East Asia Tsunami). Climate changes are expected to impact vegetation as manifested by changes in vegetation extent, migration of species, tree species composition, growth rates, and mortality. The International Panel on Climate Change (IPCC) has included discussions on how forests may be impacted, and how they may be used to mitigate the impacts of changes in climate, to possibly slow the rate of change. This book provides current scientific information on the biological and economical impacts of climate changes in forest environments, as well as information on how forest management activities might mitigate these impacts, particularly through carbon sequestration. Case studies from a wide geographic range are presented. This information is beneficial to managers and researchers interested in climate change and impacts upon forest environments and economic activities. This volume, which forms part of Springer's book series Managing Forest Ecosystems, presents state-of-the-art research results, visions and theories, as well as specific methods for sustainable forest management in changing climatic conditions.

Plants are unique as their development and morphogenesis are plastic throughout their lives. They continuously monitor diverse biotic and abiotic parameters of their environment and these sensory perceptions shape their organs and bodies. Although genes are critical, the final form and architecture of above-ground organs, and es- cially of root systems, are determined by their sensory activities associated with motoric responses (Friml 2003; Hodge 2009). Sensory plant biology and plant el- trophysiology were two lively disciplines until the late 1970s (Bunning 1959; Haupt and Feinleib 1979) but then, for somewhat obscure reasons, they showed no further development. In the last few years, however, there have been numerous advances in plant sciences. These necessitate not just a revival of plant electrophysiology and sensory biology, but also the introduction of plant neurobiology, which includes also plant sensory ecology (Balu ka et al. 2006a; Brenner et al. 2006). First of all, and contrary to all "mechanistic" predictions based on the high turgor pressure of plant cells, endocytosis has been found to be an essential process of plant cells which impinges upon almost all aspects of plant life ( amaj et al. 2005, 2006). Moreover, recent advances in plant molecular biology have identified, besides classic n- rotransmitters, also several proteins typical of animal neuronal systems, such as acetylcholine esterases, glutamate receptors, GABA receptors, and endocannabinoid signaling components, as well as indicating signaling roles for ATP, NO, and re- tive oxygen species (Balu ka et al. 2006b)."

Holism and reductionism are traditionally seen as incompatible views or approaches to nature. Here Looijen argues that they should rather be seen as mutually dependent and hence co-operating research programmes. He sheds some interesting new light on the emergence thesis, its relation to the reduction thesis, and on the role and status of functional explanations in biology. He discusses several examples of reduction in both biology and ecology, showing the mutual dependence of holistic and reductionist research programmes. Ecologists are offered separate chapters, clarifying some major, yet highly and controversial ecological concepts, such as `community', `habitat', and `niche'. The book is the first in-depth study of the philosophy of ecology. Readership: Specialists in the philosophy of science, especially the philosophy of biology, biologists and ecologists interested in the philosophy of their discipline. Also of interest to other scientists concerned with the holism-reductionism issue.

This volume contains a selection of 14 articles dealing with different aspects of biomonitoring and their relation to questions of global change. During the last 10 - 15 years, vegetation changes due to various causes have been more intensively studied in biological and environmental sciences. Especially aspects of global warming lead to a great variety of tasks for vegetation science (see e.g. the articles by Grabherr, Gottfried & Pauli; Carraro, Gianoni, Mossi, KlOtzli & Walther; Walther; Defila; Stampfli & Zeiter; Rothlisberger; Burga & Perret and Moller, WUthrich & Thannheiser). The different aspects of applied biomonitoring related to (possible) environmental changes concern various ecosystems, e.g. Central European beechwoods, Insubrian evergreen broad-leaved forests, thermophilous lowland deciduous forests, dry grasslands of the lower montane belt of the Ticino Alps, alpine mountain peaks of Switzerland and Austria, Swiss alpine timberline ecotones, and high arctic tundra vegetation. The volume is divided into three parts: A. General aspects of biomonitoring (contributions by KlOtzli; Wildi and Labasch & Otte) , B. Examples of applied biomonitoring in Germany and Switzerland (articles by Hakes; Herpin, Siewers, Kreimes & Markert; Defila; Stampfli & Zeiter; Rothlisberger and Ruoss, Burga & Eschmann), and C. Aspects of global change in the Alps and in the high arctic tundra (Grabherr, Gottfried & Pauli; Burga & Perret; Carraro, Gianoni, Mossi, KlOtzli & Walther; Walther and Moller, WUthrich & Thannheiser).

Original studies address key aspects of the conservation and biodiversity of plants. Articles are all peer-reviewed primary research papers, contributed by leading biodiversity researchers from around the world. Collectively, these articles provide a snapshot of the major issues and activities in global plant conservation. Many of the articles can serve as excellent case studies for courses in ecology, restoration, biodiversity, and conservation.

The inspiration for this book came from our ten years of journeys and wanderings through the varied landscapes of Arabia, and in particular through those of its hospitable southeastern corner, Oman. We owe a particular debt to Sultan Qaboos University, which during this time has provided us with both a stimulating working environment and a home. Transliteration of Arabic place and other names into English script is a task fraught with difficulties. We have followed 'accepted' spellings wherever these were not contrary to our common sense, and in other cases we have rendered names into Roman English script using phonetic spellings. Our main task in this respect was to ensure conformity between the fIfteen contributing authors. Diacritical signs have mostly been avoided, since their use is neither widely followed nor readily understood. Arabic words which have been commonly taken into the English language, such as 'sabkha' for a salt flat and 'wadi' for a valley with a seasonal watercourse, are not italicised in usage. However, other Arabic terms which are occasionally used in English but not as widely known, such as harrah for a basaltic lava fIeld and hima for a traditional grazing reserve, are italicised throughout the text.

Known as "a dream place for scientists" the Lamto savannas, located on the edge of the Cote d'Ivoire rain forests, are some of the only savannas in the world where ongoing ecological research has endured for over forty years. Drawing from and synthesizing this abundance of research, the book examines the structure, function, and dynamics of the Lamto humid savanna. Beginning with the history of the Lamto ecology station, proceeding on to an overview of the major enivronmental conditions of the site, and specifically examining the integrative view of energy and nutrient fluxes relative to the dynamics of the region's vegetation, this exacting work is as unique and treasured as Lamto itself.

Countless ants transport and deposit seeds and thereby influence the survival, death, and evolution of many plant species. In higher plants, seed dispersal by ants (myrmecochory) has appeared many times independently in different lineages. More than 3000 plant species are known to utilize ant assistance to be planted. Myrmecochory is a very interesting and rather enigmatic form of mutualistic ant-plant associations. This phenomenon is extremely complex, because there are hundreds of ant species connected with hundreds of plant species. This book effectively combines a thorough approach to investigating morphological and physiological adaptations of plants with elegant field experiments on the behaviour of ants. This monograph is a first attempt at collecting information about morphology, ecology and phenology of ants and plants from one ecosystem. The book gives readers a panoramic view of the hidden, poorly-known interrelations not only between pairs of ants and plant species, but also between species communities in the ecosystem. The authors have considered not just one aspect of animal-plant relationships, but have tried to show them in all their complexity. Some aspects of the ant-plant interactions described in the book may be of interest to botanists, others to zoologists or ecologists, but the entire work is an excellent example of the marriage of these biological disciplines.

This volume is the result of an invited symposium titled "Integrated Land-Use and Environmental Models: A Survey of Current Applications and Research" that was held in October 2000 at Arizona State University. The idea for the symposium arose from a belief held by many academics that we are at the watershed of a new generation of models that are more dynamic, more pragmatic, more interdiscipli nary, and more amenable to collaborative decision making. Several academics and professionals engaged in urban research had long realized that domain-specific knowledge was inadequate for understanding and managing urban growth. While interdisciplinary approaches have become critical in most social research, one general area of knowledge that stands out as having the most wide-ranging impact on current urban modeling efforts is the field comprised of environmental sciences and ecology. The symposium offered a forum for academics and professionals engaged in urban and ecological modeling to exchange ideas and experiences, specifically in areas that overlapped urban and environmental issues. The contri butions to this volume highlight the progress made in the various efforts to build integrated urban and environmental models. More importantly, each chapter shows how ideas have diffused across disciplinary boundaries to create better policy-relevant models. In addition, this book outlines some promising areas of research that could make important contributions to the field of urban and envi ronmental modeling. Integrated thinking about urban and environmental issues has been fundamental to the concept of sustainability."

The idea for the volume first came about through a conversation the editors had at the Sustainable Management of Soil Organic Matter Conference in Edinburgh in September 1999. It developed with two symposia on Amazonian dark earths that were held in 2001 in conjunction with the Conference ofLatin Americanist Geographers in Benicassim, Spain, and the Congress of the Brazi- lian Archaeological Society in Rio de Janeiro, Brazil, respectively, and culmi- nated at the First International Workshop on Terra Preta Soils held in Manaus and Santarem, Brazil, in July 2002. As a comprehensive treatment of these dis- tinctive anthropogenic soils has never been published, we decided to select papers from these symposia and develop an edited volume. The result con- tains the efforts of an international group of distinguished scholars from the disciplines of anthropology, archaeology, biology, geography, and soil science. The 15 chapters of this volume provide an array of interesting and comple- mentary interpretative stances developed from a diverse body of investigative methodologies. The readerwill note that there are some inconsistencies inter- minology and differences in interpretation among the chapter presentations. However, the editors purposely allowed these to remain and retained as much as possible of the authors' own words, since we feit that it was important to maintain the flavor of the symposium atmosphere in this volume and conse- quently did not intentionally force standardization upon the authors.

Spontaneous self-cloning or clonality is a widespread phenomenon in the plant kingdom, and has a wide array of ecological and evolutionary implications. This volume is the outcome of an international workshop on clonal plant biology aimed at illustrating current progress and recent developments in the scientific study of clonality in plants. The first section of this book includes a collection of original research articles which demonstrate the wide variety of approaches and scientific challenges linked to clonality in plants. The topics covered in this section include ecological and evolutionary implications of sexual versus asexual propagation, including life-history evolution and sex-ratio dynamics, the importance of internal resource transport and remobilization of storage products for the invasiveness and competitiveness of clonal plants, a survey of clonal growth forms in grassland communities, and studies on the interactions between clonal plants and animals and fungi. The approaches used range from experimental studies on a broad variety of systems to mathematical modeling of clonal growth and its consequences. The second part features discussion and review papers on a diverse array of subjects, ranging from developmental considerations of clonality, principles of selection and evolution in clonal plants, a survey of clonality in algae, to potential implications of clonality for plant mating, and beyond. This part of the volume aims at presenting novel ideas and hypotheses, and at summarizing existing knowledge in previously under-researched areas, thereby providing directions for future research initiatives.

This book captures ongoing cutting-edge research in the field of clonal plant ecology and evolution. It is directed to anyone from the undergraduate to specialist level who is interested in the biology of the intriguing phenomenon of asexual propagation in plants.

This book marshals ecological literature from the last century on facilitation to make the case against the widely accepted individualistic notion of community organization. It examines the idea that positive interactions are more prevalent in physically stressful conditions. Coverage also includes species specificity in facilitative interactions, indirect facilitative interactions, and potential evolutionary aspects of positive interactions.

The assimilation of sulfur in higher plants and its reduction in metabolically important sulfur compounds are crucial factors determining plant growth and vigor and resistance to stresses. The present book discusses the aspects of sustainable crop production with sulfur, the importance of sulfur metabolites and sulfur metabolizing enzymes in abiotic stress management in plants. The book provides the most up-to-date reference on sulfur assimilation in plants.

Recent years have brought an upsurge of interest in the study of arbuscular mycorrhizal (AM) fungi, partly due to the realization that the effective utilization of these symbiotic soil fungi is likely to be essential in sustainable agriculture. Impressive progress has been made during the last decade in the study of this symbiosis largely as a result of increasing exploitation of molecular tools. Although early emphasis was placed on the use of molecular tools to study physiological processes triggered by the symbiosis, such as expression of symbiosis-specific polypeptides and modulation of host defences, other applications await. It was obvious to us that gathering leaders in the field to summarize these topics and point out research needs was necessary if we were to understand the physiology and function of AM fungi at a molecular level. In addition, we have taken the opportunity to present these reviews in a logical sequence of topics ranging from the initiation of the life cycle of the fungus to its functions in plant growth and in the below ground ecosystem. It was a challenge to limit this flood of information to the confines of one text. This is a very exciting time for mycorrhiza biologists and it is our hope that some of this excitement is conveyed to our readers.

Flowering plants dominate much of the Earth's surface and yet, as sessile organisms, they must constantly resist attack by numerous voracious herbivores. Survival in the face of an abundance of insect predators relies on sophisticated resistance systems allowing plants to escape from herbivory in time or in space, to confront herbivores directly, or to fight them indirectly by remarkable collaborations with other species. Until recently, plant resistance was believed to be constitutive, i.e. ever-present and independent from herbivore attack. However, plants were discovered to respond actively to herbivory through the mobilization of specific defenses, and this discovery opened an exciting new field of research.
This book provides a thorough overview of the anatomical, chemical, and developmental features contributing to plant defense, with particular emphasis on plant responses that are induced by wounding or herbivore attack.

There are many good books in the market dealing with the subject of allelopathy. When we designed the outline of this new book, we thought that it should include as many different points of view as possible, although in an integrated general scheme. Allelopathy can be viewed from different of perspectives, ranging from the molecular to the ecosystem level, and including molecular biology, plant biochemistry, plant physiology, plant ecophysiology and ecology, with information coming also from the organic chemistry, soil sciences, microbiology and many other scientific disciplines. This book was designed to include a complete perspective of allelopathic process. The book is divided into seven major sections. The first chapter explores the international development of allelopathy as a science and next section deals with methodological aspects and it explores potential limitations of actual research. Third section is devoted to physiological aspects of allelopathy. Different specialists wrote about photosynthesis, cell cycle, detoxification processes, abiotic and biotic stress, plant secondary metabolites and respiration related to allelopathy. Chapters 13 through 16 are collectively devoted to various aspects of plant ecophysiology on a variety of levels: microorganisms, soil system and weed germination. Fundamental ecology approaches using both experimental observations and theoretical analysis of allelopathy are described in chapters 16 and 17. Those chapters deal with the possible evolutionary forces that have shaped particular strategies. In the section named "allelopathy in different environments", authors primarily center on marine, aquatic, forest and agro ecosystems. Last section includes chapters addressing application of the knowledge of allelopathy.

One of the central research themes in ecology is evaluating the extent to which biological richness is necessary to sustain the Earth's system and the functioning of individual ecosystems. In this volume, for the first time, the relationship between biodiversity and ecosystem processes in forests is thoroughly explored. The text examines the multiple effects of tree diversity on productivity and growth, biogeochemical cycles, animals, pests, and disturbances. Further, the importance of diversity at different scales, ranging from stand management to global issues, is considered. The authors provide both extensive reviews of the existing literature and own datasets. The volume is ideally suited for researchers and practitioners involved in ecosystem management and the sustainable use of forest resources.

This innovative book integrates practical information from restoration projects around the world with the latest developments in successional theory. It recognizes the critical roles of disturbance ecology, landscape ecology, ecological assembly, invasion biology, ecosystem health, and historical ecology in habitat restoration. It argues that restoration within a successional context will best utilize the lessons from each of these disciplines.

The area of eastern Africa, which includes Tanzania and Kenya, is known for its savannas, wildlife and tribal peoples. Alongside these iconic images lie concerns about environmental degradation, declining wildlife populations, and about worsening poverty of pastoral peoples. East Africa presents in microcosm the paradox so widely seen across sub Saharan Africa, where the world s poorest and most vulnerable populations live alongside some of the world s most outstanding biodiversity resources.

Over the last decade or so, community conservation has emerged as a way out of poverty and environmental problems for these rural populations, focusing on the sustainable use of wildlife to generate income that could underpin equally sustainable development. Given the enduring interest in East African wildlife, and the very large tourist income it generates, these communities and ecosystems seem a natural case for green development based on community conservation.

This volume is focused on the livelihoods of the Maasai in two different countries - Kenya and Tanzania. This cross-border comparative analysis looks at what people do, why they choose to do it, with what success and with what implications for wildlife. The comparative approach makes it possible to unpack the interaction of conservation and development, to identify the main drivers of livelihoods change and the main outcomes of wildlife conservation or other land use policies, while controlling for confounding factors in these semi-arid and perennially variable systems. This synthesis draws out lessons about the successes and failures of community conservation-based approach to development in Maasailand under different national political and economic contexts and different local social and historical particularities.

Seasonality is so obvious that we very often forget about it when doing landscape research. Seasonality is the interface where humans and nature really interact. Seasonality is expressed both in the natural rhythms of the landscape as well as in human lifestyles. Seasonality creates varying patterns of use and appears in spatial practices, paintings, human behaviour. Also, seasonality itself changes together with societal changes in agricultural societies, summer used to be the working season and winter the resting one; now we are more and more used to summer holidays

Landscapes are seasonal both in terms of time and space, the boundaries between seasons are celebrated do different seasonalities influence also our mindsets? In most cases we talk about (and paint and study) summer landscapes, but there are more than that. There are times with less light, less leaves on the trees to influence visibility, times when moist or snow make places inaccessible. Should seasonality be taken into account in planning, and if yes, then how?

This book studies seasonal landscape in Scandinavia and Brazil, on the Aegean islands and in European mountains, in agriculture tourism, in cities and in the countryside. "

The goal of this transdisciplinary book is to identify the problems and challenges facing implementation of the Convention on Biological Diversity (CBD) - from the global, regional and local points of view. The valuation and conservation of biodiversity are critical first steps necessary for the adequate protection of the environment. The authors give insights into the the influences the CBD exerts, and current trends in the field.

This book provides a first overview of the phemonemon of post-industrial urban wilderness: urban landscapes once shaped by heavy industry that are being re-colonized naturally by forests. These new types of urban woodlands are often overlooked by ecologists, foresters and planners. Individual chapters consider urban woodlands from the perspectives of ecology, environmental sociology, forestry, nature conservation and landscape architecture.

In North America, Juniperus woodlands occupy approximately 55 million hectares, an area larger than the state of Texas. This title addresses various aspects of the biology, ecology, and management of Juniperus woodlands and savannas, synthesizing past and current research findings as well as proposed research. The book provides ecologists, land managers, and foresters with a solid foundation in Juniperus ecosystems, enabling them to manage the communities for maximum sustained productivity and diversity.

Capitalizing on forty years of intensive ecological studies, this anthology presents a collection of widely dispersed major publications on theoretical and practical Mediterranean, global environmental and landscape issues. Each chapter features a comprehensive study of ecological and landscape issues, synthesized in the introduction, and woven with autobiographical experiences. The concluding chapter calls for a transdisciplinary shift in all environmental scientific fields and particularly in landscape and restoration ecology, to cope with the complex, closely interwoven ecological, socio-economical, political and cultural crises facing human society during the present crucial transition from the industrial to the post-industrial, global information age.

Updating and broadening the scope of the groundbreaking Springer book on Landscape Theory and Applications by the author and Lieberman (1994), this is a unique transdisciplinary attempt based on advanced systems complexity theories, which link the natural and human sciences.
