Indian screw pine family Pandanaceae represents three genera, in which genus Pandanus and Benstonea are distributed in two hotspots in India the Western Ghats and the Northeast Himalayan region. For the first time, Indian Pandanaceae has been assessed for its taxonomic status and phylogenetic relationship. The extensive survey by the authors led to the discovery of three new Pandanus species (two from the Western Ghats and one from the Northeast Himalaya). The present taxonomic revision confirmed total number of Pandanus species to 14 that are distributed in the Southern India (9 species) and Northeast Himalayan region (5 species). Genus Benstonea is represented by two species, one from Southern India and another species common to both regions. A detailed species identification key is given along with conservation status of each species following IUCN Red List Categories and Criteria (2001). The study revealed that, out of 16 Pandanus and Benstonea species, six species are under threatened categories.

In recent years, a chloroplast DNA-based molecular phylogenetic approach has been followed to understand the evolutionary relationship among the plant species. The interrelationship among the 14 Pandanus species at infrageneric level has been worked out using this approach, which has led to the rearrangement of some species to the subgenera proposed by Stone (1974). Moreover, the close relationship between Pandanus and Benstonea has been confirmed and the interrelationship of Indian Pandanus genus in global context is given. This book also describes the economic importance of each Pandanus species.

Air pollution affects every living organism, including all kinds of vegetation on which we depend for survival. The second edition of this standard reference textbook provides a comprehensive and up-to-date overview of the direct and indirect impacts of air pollution on plant life. Written by an international team of experts, the book also covers the main historical aspects and sources of pollutants, atmospheric transport and transformations of pollutants, and issues of global change and the use of science in air pollution policy formulation.

Air Pollution and Plant Life Second Edition is a unique text in several ways:

• covering all the main phytotoxic pollutants with due consideration given to impacts at all levels of plant organisation from molecular to ecological.

• emphasising the effects of air pollutants in altering plant response to common stresses, both abiotic and biotic - fields in which considerable progress has been made since publication of the first edition.

• and including coverage of how research leads to pollution control policy development.

This book offers a comprehensive overview of the phytosociological information currently available in Morocco - a country famous for its floristic and landscape diversity. There has been little literature on the topic; however, in recent decades there have been a number of advances in the field of vegetation communities in the country, and several new phytosociological units have been described. This inventory includes 670 associations (communities or groupments), 97 alliances, 66 orders and 44 classes. Although these figures are underestimations, they clearly reflect the great richness and diversity of the country's ecosystems. For each association the book provides useful information, including vegetation belt, bioclimate, altitude, substrate/soil, geographical distribution and additional comments. The book is a basic tool for scientific researchers, students and naturalists interested in phytoecology in Morocco and Mediterranean Basin.

Few plant species have had as much combined scientific, public, and political attention as exotic Tamarix spp (tamarisk, saltcedar), attracting the public eye in the early 2000's when widespread drought in the West corresponded to assertions that the introduced tree used as much water as whole cities. This edited volume contains 24 essays by 44 authors on the hybrid swarm that represents invasive tamarisk, including its biology, ecology, politics, history, management, and even the philosophical and ethical issues involved with designating a particular species as "good" or "bad". These works reflect the controversy that has arisen around its role in our ecosystems and what should (or should not) be done about it, particularly in the context of the release of a biological control agent. This is the first text to examine these many facets of this interesting plant with an engaging and sometimes surprising collection of written works from the most important researchers in the field, representing the full spectrum of scientific perspectives.

Each plant species has its own unique passage that is affected by its gene pool, dispersal ability, interactions with competitors and pests, and the habitats and climactic conditions to which it is exposed. This book will explore plant species as dynamic entities within this passage, following the four stages of plant species life that normally occur. Those four stages can be identified as birth, expansion, differentiation and loss of cohesion, and decline/extinction. Each chapter focuses on part of the speciation process and examines it closely in the light of exploring the species passage from birth to death.

This book comprising 13 chapters, is the second of the four books planned for a series on Progress in Mycological Research. The chapters provide an overview of the progress and shifts that have taken place towards the understanding of the Systematics and Evolution of Fungi with the availability of modern tools and techniques. Most major groups of fungi such as the Chytridiomycota, Zygomycota, Ascomycota, and Basidiomycota have been attempted to be covered. Advances in morphological and molecular taxonomy of highly toxigenic Fusarium species and understanding the phylogeny of the alternarioid hyphomycetes have also been dealt with in their respective chapters. Methods used in fungal evolutionary biology, their theory, examples and potential applications, and proteomics research for rapid diagnosis to invasive candidiasis have been reviewed in two different chapters. The ways in which molecular biologists and morphosystematists can develop synergy between them has been elaborated in the introductory chapter.

This book provides essential information on Mexico's Holocene and Anthropocene climate and vegetation history. Considering the geography of Mexico - which is home to a variety of climatic and environmental conditions, from desert and tropical to high mountain climates - this book focuses on its postglacial paleoecology and paleoclimatology. Further, it analyses human intervention since the middle Holocene as a major agent of environmental change. Offering a valuable tool for understanding past climate change and its relationship with present climate change, the book is a must-read for botanists, ecologists, palaeontologists and graduate students in related fields.

The book offers a comprehensive review of the advances in conservation and the reintroduction of rare and endangered plants in China.

A useful reference resource for students, instructors and scientific researchers in the field of wild plant protection, botany, biodiversity protection, and natural land protection and management, the book also provides valuable insights for government departments involved in plant management.

Ferns, collectively, represent an ancient species of vascular plant which has a direct connection to the beginning of life on Earth. Today they are valued for their ornamental appeal, environmental benefit or as sources of health benefiting metabolites. Current pteridology, the study of fern, encompasses a wide range of research activities including, but not limited to, plant physiology, stress tolerance, genetics and genomics. The goal of this book is to compile the most relevant research done with ferns during the last decade. It is organized into four parts: I, Biology and Biotechnology; II, Evolution and Conservation; III, Metabolism and Genetic Resources, and IV, Environment. Each section reveals the utilization of ferns as a tool to explore challenges unique to plant development and adaptation. This project represents our collective effort to raise the awareness of ferns as a model system to study higher plant functions. Among the distinctive features of our proposed book are: (i) a wide range of topics with contributing researchers from all around the world, and (ii) recent advances of theoretic and applied knowledge with implications to crop species of economic value.

This book addresses an important problem in ecology: how are communities assembled from species pools? This pressing question underlies a broad array of practical problems in ecology and environmental science, including restoration of damaged landscapes, management of protected areas, and protection of threatened species. This book presents a simple logical structure for ecological assembly and addresses key areas including species pools, traits, environmental filters, and functional groups. It demonstrates the use of two predictive models (CATS and Traitspace) and consists of many wide-ranging examples including plants in deserts, wetlands, and forests, and communities of fish, amphibians, birds, mammals, and fungi. Global in scope, this volume ranges from the arid lands of North Africa, to forests in the Himalayas, to Amazonian floodplains. There is a strong focus on applications, particularly the twin challenges of conserving biodiversity and understanding community responses to climate change.

How do you record the wildlife in a wood? This book explains ways to record the flora and fauna found in woodland and outlines the sources you can use to find out more about the history and management of an area. Whether you have just a few hours, or a few years, there are examples that you can follow to find out more about this important habitat. Woods include some of the richest terrestrial wildlife sites in Britain, but some are under threat and many are neglected, such that they are not as rich as they might be. If we are to protect them or increase their diversity we need first to know what species they contain, how they have come to be as they are, to understand how they fit into the wider landscape. Conservation surveys are the bedrock on which subsequent protection and management action is based. There is not one method that will be right for all situations and needs, so the methods discussed range from what one can find out online, to what can be seen on a general walk round a wood, to the insights that can come from more detailed survey and monitoring approaches. Fast-evolving techniques such as eDNA surveys and the use of LiDAR are touched on.

This book tackles the challenging issues raised by the growth of large megacities from diverse perspectives and approaches. The central question raised by the growth of megacities is what effect their growth will have on the ability of the global population to live in sustainable, livable, and safe societies. In Part I, important issues on the relationships between megacities and sustainability of the global environment are specified. Part II shows what can be learned from the history and diversity of megacities to solve challenging issues of the present. We present practical approaches that can solve the issues of megacities particularly focusing on human activities that seek the more harmonious relationship between life amenities and the natural environment: population density and urban built environment; production and trade; and environmental education and enlightenment. Part III aims to answer the question, what aspects of megacities should be measured and assessed? Barometers are necessary to control human activities in megacities. We consider how to measure and assess performances of megacities, reviewing some cases of indicators that authors have developed. This publication highlights the challenging issues of the relationships between megacities and sustainability of the global environment and related issues that have accrued from them, based on the following three scales: long-term time scale from the past to the present and future; a vast spatial scale that links global space with local spaces; and the scale of various aspects of human socio-economic activities in megacities.

Soil quality is threatened by many human-induced activities, but can also be improved by good land management. In the relatively short history of mankind on earth, the landscape and soils of the world have been drastically modified from their "natural " state. Landscapes altered by man's activities are termed "Anthroscapes" which are inextricably linked to culture and history. The challenges for today's scientists are to devise and implement sustainable land management strategies in order to preserve the land for the benefit of future generations. This book is a valuable compendium of the research experiences so far gained in studies of the context and concept of the "Anthroscape" and highlights the potential future contributions of such research to sustainable development.

How do plants make a living? Some plants are gamblers, others are swindlers. Some plants are habitual spenders while others are strugglers and miserly savers. Plants have evolved a spectacular array of solutions to the existential problems of survival and reproduction in a world where resources are scarce, disturbances can be deadly, and competition is cut-throat. Few topics have both captured the imagination and furrowed the brows of plant ecologists, yet no topic is more important for understanding the assembly of plant communities, predicting plant responses to global change, and enhancing the restoration of our rapidly degrading biosphere. The vast array of plant strategy models that characterize the discipline now require synthesis. These models tend to emphasize either life history strategies based on demography, or functional strategies based on ecophysiology. Indeed, this disciplinary divide between demography and physiology runs deep and continues to this today. The goal of this accessible book is to articulate a coherent framework that unifies life history theory with comparative functional ecology to advance prediction in plant ecology. Armed with a deeper understanding of the dimensionality of life history and functional traits, we are now equipped to quantitively link phenotypes to population growth rates across gradients of resource availability and disturbance regimes. Predicting how species respond to global change is perhaps the most important challenge of our time. A robust framework for plant strategy theory will advance this research agenda by testing the generality of traits for predicting population dynamics.

Natural forests with thousands of years of ecological continuity are unrivalled as the treasure store of terrestrial biodiversity on Earth. And while there is currently no fully comprehensive inventory of the biota associated with any given forest, it is reasonable to assume that in conserving natural forests we can conserve the myriads of unnamed bacteria, fungi, insects, mites and nematodes that forests support.

Drawing on diverse research from biodiversity experts around the world, this collection of papers reflects the diversity of forest types and forest issues that concern forest scientists globally. Forest types considered vary from savannah and tropical rainforests to the ancient oak forests of Poland; issues explored include the effects of logging, management practices, forest dynamics and climate change on forest structure and biodiversity.

Given the range of topics covered, this book should be of particular interest to those involved in teaching forest conservation and management, as well as to researchers requiring an overview of current work in forest diversity, conservation and sustainable management.

Plant remains can preserve a critical part of history of life on Earth. While telling the fascinating evolutionary story of plants and vegetation across the last 500 million years, this book also crucially offers non-specialists a practical guide to studying, dealing with and interpreting plant fossils. It shows how various techniques can be used to reveal the secrets of plant fossils and how to identify common types, such as compressions and impressions. Incorporating the concepts of evolutionary floras, this second edition includes revised data on all main plant groups, the latest approaches to naming plant fossils using fossil-taxa and techniques such as tomography. With extensive illustrations of plant fossils and living plants, the book encourages readers to think of fossils as once-living organisms. It is written for students on introductory or intermediate courses in palaeobotany, palaeontology, plant evolutionary biology and plant science, and for amateurs interested in studying plant fossils.

The species-area relationship (SAR) describes a range of related phenomena that are fundamental to the study of biogeography, macroecology and community ecology. While the subject of ongoing debate for a century, surprisingly, no previous book has focused specifically on the SAR. This volume addresses this shortfall by providing a synthesis of the development of SAR typologies and theory, as well as empirical research and application to biodiversity conservation problems. It also includes a compilation of recent advances in SAR research, comprising novel SAR-related theories and findings from the leading authors in the field. The chapters feature specific knowledge relating to terrestrial, marine and freshwater realms, ensuring a comprehensive volume relevant to a wide range of fields, with a mix of review and novel material and with clear recommendations for further research and application.

In this translation of the French edition (L'U. de Saint-'etienne, 1999), the author treats the interrelated factors that inform plants' adaptations to their environments. Applying ecophysiological principles to identify mechanisms of dysfunction in ecosystems, he presents data-based cases for: less stressful growing methods (e.g., using cultivars that require less water and polluting fertilizers); confining genetically modified organisms to the lab; and reality-based holistic studies.

This book is a comprehensive review of the genera of Ophioglossaceae, the adder's-tongue family, found in tropical East Africa. It presents information on their character, occurrence, habitat, phenotypic variations and distribution of each of the species under these genera.

A detailed account of the biology and ecology of vascular wetland plants and their applications in wetland plant science, Wetland Plants: Biology and Ecology presents a synthesis of wetland plant studies and reviews from biology, physiology, evolution, genetics, community and population ecology, environmental science, and engineering. It provides a thorough discussion of the range of wetland plants adaptations to conditions such as life in water or saturated soils, high salt or high sulfur, as well as low light and low carbon dioxide levels.

The authors include the latest research on the development of plant communities in newly restored or created wetlands and on the use of wetland plants as indicators of ecological integrity and of wetland boundaries. Over 140 figures, including over 70 original photographs, allow you to visualize the concepts, 40 tables give you easy access to definitions and data, and international examples provide you with a broad base of information.

The growing consensus in wetlands literature and research suggests that methods are needed to assess the ecological health or integrity of wetlands, to set goals for wetland restoration, and to track the status and trends of wetlands. Wetland plants are emerging as important indicators, and becoming an important part of this research. Wetland Plants: Biology and Ecology contains up-to-date information on this increasingly important area in wetlands technology.

Used by humans since ancient times, evergreen oak forests still cover extensive mountain areas of the Mediterranean Basin. These broadleaved evergreen forests occupy a transitional zone between the cool-temperate deciduous forest biome and the drier Mediterranean pine forests and shrublands. Slow growing and casting a deep shade, the sclerophyllous holm oak ("Quercus ilex") absolutely dominates the closed canopy of many Mediterranean evergreen oak forests. This is a synthesis of 20 years of research on the structure, function, and dynamics of holm oak forests in two intensively studied experimental areas in Spain. By combining observational measurements at the leaf, tree, plot, and catchment scales with field experiments and modelling, the authors explore how these forests cope with strong water limitation and repeated disturbances.

^iEco-Hydrology is the first book to offer an overview of the complex relationships between plants and water across a wide range of terrestrial and aquatic environments. Leading ecologists and hydrologists present reviews of the eco-hydrology of drylands, wetlands, temperate and tropical rain forests, streams, and rivers and lakes. The authors present background information on the water relations of plants, from individual cells to stands of plants, the role of mathematical models in eco-hydrology, and explanations of how plants affect patterns and rates of water movement and storage in a range of terrestrial and aquatic ecosystems.

It is a distressing truism that the human race during the last millennium has caused the exponential loss of plant genetic diversity throughout the world. This has had direct and negative economic, political and social consequences for the human race, which at the same time has failed to exploit fully the positive benefits that might result from conserving and exploiting the world's plant genetic resources. However, a strong movement to halt this loss of plant diversity and enhance its utilisation for the benefit of all humanity has been underway since the 1960's (Frankel and Bennett, 1970; Frankel and Hawkes, 1975). This initiative was taken up by the Convention on Biological Diversity (CBD, 1992) that not only expounds the need to conserve biological diversity but links conservation to exploitation and development for the benefit of all. Article 8 of the Convention clearly states the need to develop more effective and efficient guidelines to conserve biological diversity, while Article 9, along with the FAO International Undertaking on Plant Genetic Resources, promotes the adoption of a complementary approach to conservation that incorporates both ex situ and in situ techniques.
