Remediation of contaminants caused by growing human civilization and industrialization is a serious environmental issue. Recent research has shown that soil microorganisms play an important role in remediating and improving disturbed ecosystems. This approach is eco-friendly and relatively less expensive. The present book covers the investigations carried out using microbes for restoration of degraded eco-systems. Please note: This volume is Co-published with New India Publishing Agency, New Delhi.

'A bold, ambitious and truly wonderful history of the world' Peter Wohlleben, author of The Hidden Life of Trees 'A fascinating story and a crucial revision of the momentous importance of tropical forests to human history' Lewis Dartnell, author of Origins _________________________ Jungle tells the remarkable story of the world's tropical forests, from the arrival of the first plants millions of years ago to the role of tropical forests in the evolution of the world's atmosphere, the dinosaurs, the first mammals and even our own species and ancestors. Highlighting provocative new evidence garnered from cutting-edge research, Dr Roberts shows, for example, that our view of humans as 'savannah specialists' is wildly wrong, and that the 'Anthropocene' began not with the Industrial Revolution, but potentially as early as 6,000 years ago in the tropics. We see that the relationship between humankind and 'jungles' is deep-rooted, that we are all connected to their destruction, and that we must all act to save them. Urgent, clear-sighted and original, Jungle challenges the way we think about the world - and ourselves. _________________________ 'Welcome to the "Jungle" - a breathtaking book' Mark Maslin, author of How to Save Our Planet 'Timely, readable and highly relevant' Steve Brusatte, author of The Rise and Fall of the Dinosaurs 'Its revelations and stories will stir, rearrange and populate your mind for years to come' Paul Hawken, editor of Drawdown 'Brilliant ... it delivers a timely warning about our abuse of the environment' David Abulafia, author of The Great Sea 'Finally, a book on rainforests that does justice to their majesty and importance' Simon Lewis, co-author of The Human Planet

This book provides a comprehensive review on the status of iron nutrition in plants. It contains updated reviews of most relevant issues involving Fe in plants and combines research on molecular biology with physiological studies of plant-iron nutrition. It also covers molecular aspects of iron uptake and storage in Arabidopsis and transmembrane movement and translocation of iron in plants. This book should serve to stimulate continued exploration in the field.

Internationally, the wetlands of headwater and upland regions provide many valuable environmental services. They influence flood flows, sediment loads and aquifer recharge; biochemical water qualities and biodiversity. They affect the livelihoods of many communities providing water, peat, timber, grazing, crops and, locally, aesthetic, cultural, recreational, nature conservation and educational benefits. Previously, many of these lands were valued only for their capacity to be converted to other uses through drainage and forestation. Today, their benefits are better appreciated. Better environmental management highlights ways of bringing enhanced benefits from these lands to all stakeholders and of minimising their potentially negative impacts due to climatic emissions of greenhouse gases, hydrological changes (especially flooding, water chemistry) and sediment release. This book moves towards a more comprehensive inventory of the benefits and costs of headwater wetlands. It evaluates the research that tries to understand the tolerances, exchanges, checks and balances within headwater landscapes and the downstream impacts of changes in wetlands. It employs case studies and reviews from 21 nations spanning Europe, Africa, Asia and the Americas. It explores the new policy frameworks, changes in land husbandry, new systems for community education, participatory processes and technological interventions required for the effective management of headwater wetlands and the full integration of wetlands (including newly constructed wetlands) into environmental management and planning. In the past, most research dealt with wetlands as isolated features, this book examines wetlands in theirwatershed management context.

This book examines the sophisticated mechanisms that plants use to defend themselves against attack by insects and pathogens, focusing on the networks of plant signalling pathways that underlie these defences. In response to herbivory, plants release a complex blend of as many as 100 volatile chemicals, known as semiochemicals (‘sign chemicals’). These act as an airborne SOS signal, revealing the presence of the herbivore to the predators and parasitoids that are its natural enemies. Plants also have endogenous defence mechanisms that can be induced in response to pathogens, and separate chapters deal with systemic acquired resistance, phytoalexins, and the interacting pathways in pathogen and pest resistance. The book discusses underlying biochemical mechanisms by which plant stress leads to the biosynthesis of chemical signals from pools of secondary metabolite precursors, or even from the primary metabolism source. Finally, consideration is given to the possibilities for exploiting these signalling pathways by plant molecular genetics. The use of plant signals and their analogues to switch on defence pathways in crop plants is covered in depth. Bringing together contributions from entomologists, chemical ecologists, molecular biologists and plant physiologists this book is truly interdisciplinary, and will be essential reading for anyone with an interest in agricultural pest control.

Fundamental Processes in Ecology presents a way to study ecosystems that is not yet available in ecology textbooks but is resonant with current thinking in the emerging fields of geobiology and Earth System Science. It provides an alternative, process-based classification of ecology and proposes a truly planetary view of ecological science. To achieve this, it asks (and endeavours to answer) the question, "what are the fundamental ecological processes which would be found on any planet with Earth-like, carbon based, life?" The author demonstrates how the idea of fundamental ecological processes can be developed at the systems level, specifically their involvement in control and feedback mechanisms. This approach allows us to reconsider basic ecological ideas such as energy flow, guilds, trade-offs, carbon cycling and photosynthesis; and to put these in a global context. In doing so, the book puts a much stronger emphasis on microorganisms than has traditionally been the case.
The integration of Earth System Science with ecology is vitally important if ecological science is to successfully contribute to the massive problems and future challenges associated with global change. Although the approach is heavily influenced by Lovelock's Gaia hypothesis, this is not a popular science book about Gaian theory. Instead it is written as an accessible text for graduate student seminar courses and researchers in the fields of ecology, earth system science, evolutionary biology, palaeontology, history of life, astrobiology, geology and physical geography.

MARINE BOTANY

Second Edition

Unmatched in detail and breadth, this Second Edition of Marine Botany explores the startling diversity and environmental dynamics of the hundreds of micro- and macroalgae, seagrasses, mangroves, and salt marshes as well as phytoplankton (minute, free-floating photosynthetic plants) and benthic communities (attached plants) that comprise the flourishing botanical garden submerged in and around the surface of our vast oceans.

Reflecting the latest in research since the original 1981 edition, long considered the classic reference on marine plant life, this new edition's enhanced ecological perspective details the ongoing environmental challenges endured by these fragile life-forms. Viewing the structure and function of marine plant communities in the context of abiotic (light, temperature, water movement, nutrients), biotic (photosynthesis, carbon fixation, competition, predation, symbiosis), and anthropogenic influences, the book moves layer by layer through the ocean, capturing their photosynthetic and adaptive mechanisms. Pollution in the form of oil spills, heavy and radioactive metals, biological damage wrought from harvesting and aquaculture, and the harmful effects of ozone depletion and UV-B rays are detailed, along with the impact of environmental factors on morphological and anatomical adaptations. The book also describes the anthropogenic stresses endured by salt marshes, mangals, seagrass communities, and marine plants of coral reefs, concluding with possible management and restorative techniques.

Marine Botany, Second Edition is both a vivid global map and comprehensive guide to all of the flourishing forms of plant life at our oceans' surface, shores, and depths and the dynamics of their survival.

The state of the art in the area of security related civil science and technology concerning energetic materials and munitions is of pressing importance at the present time, because 10 years after the end of the cold war, in many countries in east and west, huge stockpiles of munitions still await destruction. The safety behavior of munitions and their energetic material is the determining factor for all precautionary measures for the protection of environment and population. The probability of a catastrophic reaction of munitions and their energetic components will be so more likely, the closer the munitions are to the end of their life time. Residues and undetected ordnance, recycling, destruction of ammunition and depletion or reuse of energetic materials will either cause more or less damage to environment. Scientific research and development have the aim to increase performance of munitions on one side and to improve safety in relation to unpredictable events on the other side. The impact on the environment by the production and normal use of munitions and their residues after use will acquire an increasing importance in environmental awareness. The excellent technical presentations were classified in five Groups, according to the technical programme. The "Introduction to the subject; Methods, tests and application; Insensitive and "green" munitions; Storage and transportation; and Demilitarisation and recycling" sessions, were closed by a final and general interesting discussion among participants.

This successful text examines the ecological processes that determine the size and structure of a population, and demonstrates that there are many fundamental principles that apply to populations of both animals and plants. The authors have sought to involve the text in areas where particular progress has been made and consolidated. The third edition therefore addresses the problem of the detection of chaos, buried sea-banks and herbivorey implants and looks more closely at the role of spatial scale in two-species interactions. It also introduces a major new section on the concept of the meta-population. The book is designed to be readily understood by undergraduates with little or no previous knowledge of the subject, and also to stimulate wider debate and discussion.

Vegetation, soil and climate are the most important components of ecological systems. This long-awaited fourth edition of the well-established textbook by Heinrich Walter summarizes our knowledge of the earth's ecology and constitutes the basis for a deeper understanding of the larger interrelations on a global scale.While Walter's general concept remains unchanged, the individual chapters have been completely revised, enlarged and updated. The author's intimate knowledge of practically all classes of plants and climatic zones allows him to describe the various ecological systems in close detail.This richly illustrated textbook is a must for every student in the plant sciences.

"The lack of discussion of the life histories of modular organisms is the weakness of this book that I most regret. . . . Modular organisms are different. " S. C. Steams: The Evolution of Life Histories (1992) Life-history theory endeavours to increase our understanding of the processe, s whereby the broad features of the life cycles of organisms, such as the timing and magnitude of reproduction, have evolved. Although reproductive traits have dominated as study objects due to their immediate importance for evolutionary success, much work has also been conducted on patterns of development, growth and senescence, as well as on the shifts in resource allocation related to these processes. The basic axiom of life-history theory is that patterns of life histories, such as reproductive traits, are subject to evolutionary explanation. This idea can be traced back at least as far as Darwin's Origin of Species (1859). In his discussion of plant domestication, Darwin wrote: "I cannot doubt that the continued selection of slight variations, either in the leaves, the flowers, or the fruit, will produce races differing from each other chiefly in these characters." Darwin was impressed by the success of plant breeders in moulding the growth and reproductive parameters of cultivated plants, and believed that natural selection could have a similar impact in natural populations.

This book is a guide for the identification of the indigenous forest trees of Uganda. It will be useful for those who wish to contribute towards the conservation of the forests or to plant indigenous trees. Information is provided on how to propagate and cultivate about 80 of the most valuable species. Indigenous trees provide numerous resources useful for welfare and development. They include many types of timber and non-timber forest products, such as craft materials, foods and medicines. The proximity of indigenous forest helps to moderate the local climate, making it more suitable for agriculture. Indigenous forests protect springs, therefore safeguarding water supplies more effectively than exotic trees such as pines and eucalyptus. All 450 known indigenous tree species from the forests are included. Both scientific and local names are provided, the latter in 21 languages. Local names facilitate access to knowledge and values traditionally attached to the species, useful when planning pathways of development firmly rooted in local culture. The book will be invaluable for botanists, foresters, rural development workers and members of the general public concerned about contributing to conservation and sustainable development in Uganda. Many of the species grow in neighbouring countries, so the book has relevance there too.

Biological invasions are one of the major threats to our native biodiversity. The magnitude of biodiversity losses, land degradation and productivity losses of managed and natural ecosystems due to invasive species is enormous. The ecological and environmental aspects of non-native invasive plants are of great importance to (i) understand ecological principles involved in the management of invasives, (ii) design management strategies, (iii) find effective management solutions for some of the worst invaders, and (iv) frame policies and regulations. The objectives of this book are to discuss (i) ecological approaches needed to design effective management strategies, (ii) recent progress in management methods and tools, (iii) success and failure of management efforts for some of the worst invaders, and (iv) restoration and conservation of invaded land. In an effort to achieve these objectives, contributing authors have strived to provide up-to-date information on the management of non-native invasives. Chapters included in the book are peer-reviewed by international experts working in the area. Readers will get a unique perspective on ecological aspects of the management of invasives. The book will be useful to graduate students, researchers, managers and policy makers involved in the management of exotic invasives.

Invasive species are among the greatest challenges to environmental sustainability and agricultural productivity in the world. One of the most promising approaches to managing invasive species is voluntary citizen stewardship. However, in order for control measures to be effective, private citizens often need to make sustained and sometimes burdensome commitments. Community-Based Control of Invasive Species is based on five years of research by leading scholars in natural resource and human behavioural sciences, which involved government and citizen groups in Australia and the United States. It examines questions including, 'how can citizens be engaged in voluntarily managing invasive species?', 'what communication strategies will ensure good motivation and coordination?' and 'how can governing bodies support citizens in their efforts?'. With chapters on institutional frameworks, changing governance, systems thinking, organisational learning, engagement, communication and behavioural change, this book will be a valuable reference for researchers and practitioners involved in natural resources management.

Coral reef communities are among the most complex, mature and productive ecosystems on earth. Their activity resulted in the creation of vast lime constructions. Being extremely productive and having the function of a powerful biofilter, coral reefs play an important role in global biogeochemical processes and in the reproduction of food resources in tropical marine regions. All aspects of coral reef science are covered systematically and on the basis of a holistic ecosystem approach. The geological history of coral reefs, their geomorphology as well as biology including community structure of reef biota, their functional characteristics, physiological aspects, biogeochemical metabolism, energy balance, environmental problems and management of resources are treated in detail.

The potential for development of drugs and other chemically active substance from plants is huge and has only recently become widely recognized. Moreover, it is now all the more urgent due to widespread destruction of the plants' habitats and the human ethnic groups that possess the intimate knowledge of the potential of such plants. This subject - dubbed "ethnobotany" - has great implications for conservationists worldwide.;This book tackles this subject in a new series in plant conservation sponsored by the World Wide Fund for Nature (WWF). As with each of the books in the series, it aims to give an authoritative guide to the subject in a clear, jargon-free style. It should therefore not only be of interest to academic botanists and pharmaceutical personnel but also to the many "amateur" collectors (or "parataxonomists"), as well as nature guides, and other field workers.;It is written in three parts, representing three levels of difficulty for ease of use. Working figures clarify key concepts, clear tables represent research data and examples explain case studies in some detail. The source book at the end of the book contains the most technical information, and points the way to more information. A full bibliography contains references to all cited articles and books.;This book should be of interest to conservation biologists, plant ecologists/economic botanists, ethnobotanists, conservation and aid agency personnel, agroforestry experts, anthropologists, and pharmaceutical/pharmacologists, phytochemists.

The advent of ecosystem ecology has created great difficulties for ecologists primarily trained as biologists, since inevitably as the field grew, it absorbed components of other disciplines relatively foreign to most ecologists yet vital to the understanding of the structure and function of ecosystems. From the point of view of the biological ecologist struggling to understand the enormous complexity of the biological functions within an ecosystem, the added necessity of integrating biology with geochemis try, hydrology, micrometeorology, geomorphology, pedology, and applied sciences (like silviculture and land use management) often has appeared as an impossible requirement. Ecologists have frequently responded by limiting their perspective to biology with the result that the modeling of species interactions is sometimes considered as modeling ecosystems, or modeling the living fraction of the ecosystems is considered as modeling whole ecosystems. Such of course is not the case, since understanding the structure and function of ecosystems requires sound understanding of inanimate as well as animate processes and often neither can be under stood without the other. About 15 years ago, a view of ecology somewhat different from most then prevailing, coupled with a strong dose of naivete and a sense of exploration, lead us to believe that consideration of the inanimate side of ecosystem function rather than being just one more annoying complexity might provide exceptional advantages in the study of ecosystems. To examine this possibility, we took two steps which occurred more or less simultaneously."

In a world of increasing atmospheric CO2, there is intensified interest in the ecophysiology of photosynthesis and increasing attention is being given to carbon exchange and storage in natural ecosystems. We need to know how much photosynthesis of terrestrial and aquatic vegetation will change as global CO2 increases. Are there major ecosystems, such as the boreal forests, which may become important sinks of CO2 and slow down the effects of anthropogenic CO2 emissions on climate? Will the composition of the vegetation change as a result of CO2 increase?
This volume reviews the progress which has been made in understanding photosynthesis in the past few decades at several levels of integration from the molecular level to canopy, ecosystem and global scales.

We shall limit our observations to the conditions in natural ecosystems, since it would be beyond the scope of this book to embark upon a consideration of secondary, man-made ecosystems. 2. Classification of the Geo-biosphere into Zonobiomes The biosphere is the thin layer of the earth's surface to which the phenomena connected with living matter are confined. On land, this comprises the lowest layer of the atmosphere permanently inhabited by living organisms and into which plants extend, as well as the root-containing portion of the lithosphere, which we term the soil. Living organisms are also found in all bodies of water, to the very depths of the oceans. In a watery medium, however, cycling of material is achieved by means other than those on land, and the organisms (plankton) are so different that aquatic ecosystems have to be dealt with separately. The biosphere is therefore subdivided into (a) the geo-biosphere comprising terrestrial ecosystems, and (b) the hydro-biosphere, comprising aquatic ecosystems, which is the field of hydrobiologists (oceanographers and limnologists) . Our studies are confined to the geo-biosphere (Walter 1976), which constitutes the habitat of man and is, therefore, of special interest. The prevailing climate, being the primary independent factor in the environment, can be used as a basis for further subdivision of the geo-biosphere since the formation of soil and type of vegetation are dependent upon it (see p. 3), and it has not yet been substantially influenced by man.

Plants growing in tropical alpine environments (at altitudes above the closed canopy forest and below the limit of plant life) have evolved distinct forms to cope with a hostile environment characterized by cold, drought and fire. Unlike temperate alpine environments, where there are distinct seasons of favourable and unfavourable conditions for growth, tropical alpine habitats present summer conditions every day and winter conditions every night. Using examples from all over the tropics, this fascinating account reviews, for the first time, the unique form and functional relationships of tropical alpine plants examining both their physiological ecology and population biology. It will appeal to anyone interested in tropical vegetation and plant physiological adaptations to hostile environment, as well as to researchers in biogeography and ecology.

The response of forests to global climate change is one of the most hotly contested issues in the greenhouse effect debate. Much effort is being devoted to the construction of models which describe the function of the forests and their rate of change. There are a wealth of techniques available to project large-scale vegetation patterns, all based on different underlying models that contain fundamental biological and ecological mechanisms. Vegetation Dynamics and Global Change will introduce both students and professionals to the sophisticated mathematical and computational tools used to predict the rate of change in the world's forests. It emphasizes the importance of scale in global studies. Leaders in the field of vegetation modeling cover physiological phenomena typically measured at small time and space scales; the stand dynamics of forests; large-scale models of forest dynamics; the reconstruction of forest vegetation of past climates as a way to understand current global changes; and the role of forests in the global carbon cycle. Several themes run through the book, including the need to understand how processes important at one time and space scale can be conceptualized at larger scales; the need to optimize the conceptual benefits of representing processes in detail and the attendant difficulties of estimating parameters and designing tests for elaborate models; and the need to identify the most appropriate system variables.

Since the first edition ofthis book was written, public awareness oftropical rain forests has become so great that issues involving their exploitation are the stuffofdaily newspapers, radio and television. The plight offorest-living peoples has become an international issue; concerns over the greenhouse effect and other climatic changes are often linked to rain forest destruction. At the same time, there has been an unparalleled scientific interest in the workings ofthe rain forest and an increasingconcern by economists as to its potential in balancing the books of many developing countries. The need for an advanced yet concise and up-to-date synthesis ofrecent studies and a key to the increasingly voluminous literature on rain forests is even greater than it was in 1983. There are now many highly illustrated popular books on rain forests, as well as new editions of K.A. Longman and 1. Jenik Tropical rain forest and its environment (2nd edition, 1987) and T.e. Whitmore Tropical rainforests of the Far East (2nd edition, 1984, many of the splendid illustrations from which are to be found in his rather less ambitious Introduction to tropical rain forests, 1990). Other very welcome regional accounts of rain forest biology in various parts of the tropics have appeared, notable being D.H. Janzen (ed.), Costa Rican natural history (1983); Earl of Cranbrook (ed.), Malaysia (1988); G.T. Prance and T.E. Lovejoy (eds), Amazonia (1984); A.

Presented in this document is a class of deterministic models describing the dynamics of two plant species whose characteristics are common to the majority of annual plants that have a seedbank. Formulated in terms of elementary dynamical systems, these models were developed in response to four major questions on the long-term outcomes of binary mixtures of plant species: Is ultimate coexistence possible? If not, which strain will win? Does the mixture approach an equilibrium? If so, how long does the mixture take to attain it? The book gives a detailed account of model construction, analysis and application to field data obtained from long-term trials. In the particular case study modelled, the species involved are two pastural strains whose dynamics have critical agricultural and economic implications for the areas in which they are found, including North America, the Mediterranean region and Australia. This study will be valuable to researchers and students in mathematical biology and to agronomists and botanists interested in population dynamics.

The science of botany underwent a dramatic change in the late nineteenth century. A reform movement originating in Germany took the traditionally destructive approach to the study of plant structure and physiology and transformed it into a study of plant adaptation. The young scientists who initiated this approach were influenced by factors both scientific and political. Darwin's natural selection theory and the German Reich's interest in colonial expansion provided the background for a new botanical methodology, which treated Nature as the Laboratory. The work of these botanists, including Gottlieb Haberlandt, Georg Volkens, A. F. W. Schimper, and Ernst Stahl, influenced the subsequent development of botanical science in the twentieth century and contributed significantly to the emergence of the new science of ecology. In this 1990 book, Eugene Cittadino describes in detail their early careers, their zeal for Darwinian selection theory, and their sometimes hazardous expeditions into exotic environments from Africa to the East Indies.

For centuries, people have understood that forests, and our utilisation of them, influence the climate. With modern environmental concerns, there is now scientific, governmental, and popular interest in planting trees for climate protection. This book examines the historical origins of the idea that forests influence climate, the bitter controversy that ended the science, and its modern rebirth. Spanning the 1500s to the present, it provides a broad perspective across the physical and biological sciences, as well as the humanities, to explain the many ways forests influence climate. It describes their use in climate-smart forestry and as a natural climate solution, and demonstrates that in the forest-climate question, human and sylvan fates are linked. Accessibly written with minimal mathematics, it is ideal for students in environmental and related sciences, as well as anyone with an interest in understanding the environmental workings of forests and their interactions with climate.
