This book offers a concise but comprehensive introduction to desert ecology and adopts a strong evolutionary focus. As with other titles in the Biology of Habitats Series, the emphasis in the book is on the organisms that dominate this harsh environment, although theoretical and experimental aspects are also discussed. In this updated second edition, there is a greater focus on the effects of climate change and some of its likely effects on deserts, seeing desertification as among the most serious results of climate change, leading ultimately to the increasing size of arid and semi-arid regions. The Biology of Deserts Second Edition includes a wide range of ecological and evolutionary issues including morphological and physiological adaptations of desert plants and animals, species interactions, the importance of predation and parasitism, food webs, biodiversity, and conservation. It features a balance of plant and animal (both invertebrate and vertebrate) examples, and also emphasizes topical applied issues such as desertification and invasive species. The book concludes by considering the positive aspects of desert conservation. This accessible textbook is intended for senior undergraduate and graduate students, as well as professional ecologists, conservation practitioners, and resource managers working in the field of desert ecology.

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?

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 book gathers together a wide range of contributions addressing diverse aspects of front-line human involvement in biodiversity exploitation and conservation. As such they collectively provide a snap-shot of on-going action and state-of-the-art research, rather than a series of necessarily more superficial overviews. As such it is envisaged that it will be of particular interest to courses including biodiversity and/or conservation issues, and to advanced students and researchers working in related fields. The scope of these embraces cases involving birds, crop plants, invertebrates, land use changes, livestock, mammals, marine organisms, and medicinal plants and issues related to the importance of gardens, hedges and green lanes, housing developments, hunting, invasive species, local community involvement, sacred groves, socio-economic factors, and trade.

'Kimmerer blends, with deep attentiveness and musicality, science and personal insights to tell the overlooked story of the planet's oldest plants' Guardian 'Bewitching ... a masterwork ... a glittering read in its entirety' Maria Popova, Brainpickings Living at the limits of our ordinary perception, mosses are a common but largely unnoticed element of the natural world. Gathering Moss is a beautifully written mix of science and personal reflection that invites readers to explore and learn from the elegantly simple lives of mosses. In these interwoven essays, Robin Wall Kimmerer leads general readers and scientists alike to an understanding of how mosses live and how their lives are intertwined with the lives of countless other beings. Kimmerer explains the biology of mosses clearly and artfully, while at the same time reflecting on what these fascinating organisms have to teach us. Drawing on her experiences as a scientist, a mother, and a Native American, Kimmerer explains the stories of mosses in scientific terms as well as within the framework of indigenous ways of knowing. In her book, the natural history and cultural relationships of mosses become a powerful metaphor for ways of living in the world.

Agrarian Landscapes in Transition researches human interaction with the earth. With hundreds of acres of agricultural land going out of production every day, the introduction, spread, and abandonment of agriculture represents the most pervasive alteration of the Earth's environment for several thousand years. What happens when humans impose their spatial and temporal signatures on ecological regimes, and how does this manipulation affect the earth and nature's desire for equilibrium?
Studies were conducted at six Long Term Ecological Research sites within the US, including New England, the Appalachian Mountains, Colorado, Michigan, Kansas, and Arizona. While each site has its own unique agricultural history, patterns emerge that help make sense of how our actions have affected the earth, and how the earth pushes back. The book addresses how human activities influence the spatial and temporal structures of agrarian landscapes, and how this varies over time and across biogeographic regions. It also looks at the ecological and environmental consequences of the resulting structural changes, the human responses to these changes, and how these responses drive further changes in agrarian landscapes.
The time frames studied include the ecology of the earth before human interaction, pre-European human interaction during the rise and fall of agricultural land use, and finally the biological and cultural response to the abandonment of farming, due to complete abandonment or a land-use change such as urbanization.

Air pollution poses a serious threat to human health and the environment worldwide. It contributes significantly to regional and global atmospheric issues such as global warming, acidification and depletion of the ozone layer. It affects every living thing, including all kinds of vegetation on which we depend for our survival. Although several works have appeared on air pollution, few, are able to provide the broad background that encompasses the whole gamut of plant responses to atmospheric insult. This multi--authored work integrates the varied plant growth responses to the pollution stress; the focus of the attention is plant rather than pollutant. This portrays a clearer picture of plant performance versus air pollution, and helps develop a better insight of the pollution--based disturbances at the different levels of plant life. The book shall interest both students and researchers of environmental botany and forestry as well as all those who love plants and have any interest towards global vegetation and environmental health.

The fynbos region is one of the most spectacularly diverse places on Earth. This is not an idle statement. When one considers the diversity of insects, freshwater and marine species also associated with the Cape, this hotspot is arguably the hottest of all. It is also confusingly heterogeneous, with a diversity of fine-scale habitats, from wetlands in the lowlands to seeps in the mountains, unique soil, nutrient, aspect and rainfall conditions, all of which combine to sustain and drive this diversity. Fynbos is a fire-adapted vegetation and needs fire to sustain itself: without fire the vegetation would thicken and senesce, permit trees to enter and dominate the system, and eventually exclude the precious nutrients liberated by fire and which the system depends upon for rejuvenation. This book is a guide that will help people who visit, live, manage or own land in the Fynbos Biome to appreciate and manage its extraordinary natural richness.

Mangroves are a fascinating group of plants that occur on tropical and subtropical shorelines of all continents, where they are exposed to saltwater inundation, low oxygen levels around their roots, high light and temperature conditions, and periodic tropical storms. Despite these harsh conditions, mangroves may form luxuriant forests which are of significant economic and environmental value throughout the world - they provide coastal protection and underpin fisheries and forestry operations, as well as a range of other human activities.

This book provides an up-to-date account of mangrove plants from around the world, together with silvicultural and restoration techniques, and the management requirements of these communities to ensure their sustainability and conservation.
All aspects of mangroves and their conservation are critically re-examined. Those activities which threaten their ongoing survival are identified and suggestions are offered to minimise their effects on these significant plant communities.

Pollination is one of the most important processes in plant reproduction. It directly influences reproductive success and fitness and the genetic structure of the plant population. Methods exist to infer the pattern and distance of pollen dispersal, but direct observation of the movements of individual pollen grains during pollination is not feasible owing to their small size. Single-pollen genotyping is a novel technique for genotyping a single pollen grain. In this book, the principles, the experimental protocol, and several applications of this method in studies of plant ecology, reproductive biology, and evolutionary genetics have been described. More specifically, the information is useful for the analysis of linkage disequilibrium, intraspecific genetic variation, chromosome mapping, and the origins of polyploidy. It is also essential for achieving sustainable and optimal crop yield and is vital to agriculture and forestry. Written by pioneer researchers, the book provides novel research approaches that are proving useful in a growing number of fields. This volume is intended to encourage new and continued applications of single-pollen genotyping" "among" "many disciplines in the future.

This book is an interdisciplinary, multi-author work, based upon a recently completed international study by Brazilian and British experts and will prove a valuable reference to all those working in this field.

The frontier images of America embrace endless horizons, majestic herds of native ungulates, and romanticized life-styles of nomadie peoples. The images were mere reflections of vertebrates living in harmony in an ecosystem driven by the unpre dictable local and regional effects of drought, frre, and grazing. Those effects, often referred to as ecological "disturbanees," are rather the driving forces on which species depended to create the spatial and temporal heterogeneity that favored ecological prerequisites for survival. Alandscape viewed by European descendants as monotony interrupted only by extremes in weather and commonly referred to as the "Great American Desert," this country was to be rushed through and cursed, a barrier that hindered access to the deep soils of the Oregon country, the rich minerals of California and Colorado, and the religious freedom sought in Utah. Those who stayed (for lack of resources or stamina) spent a century trying to moderate the ecological dynamics of Great Plains prairies by suppressing fires, planting trees and exotic grasses, poisoning rodents, diverting waters, and homogenizing the dynamies of grazing with endless fences-all creating bound an otherwise boundless vista. aries in Historically, travelers and settlers referred to the area of tallgrasses along the western edge of the deciduous forest and extending midway across Kansas as the "True Prairie. " The grasses thlnned and became shorter to the west, an area known then as the Great Plains."

The book provides information essential for anyone interested in the ecology of the American Southwest, including land managers, environmental planners, conservationists, ecologists and students. It is unique in its coverage of the hows and whys of dynamics (changes) in the major types of vegetation occurring on southwestern mountains and plateaus. It explains the drivers and processes of change, describes historical changes and provides conceptual models that diagrammatically illustrate past, present, and potential future changes. All major types of vegetation are covered: spruce-fir, mixed conifer, and ponderosa pine forests, pinyon-juniper vegetation, subalpine-montane grassland, and Gambel oak and interior chaparral shrublands. The focus is on vegetation that is relatively undisturbed, i.e., in natural and near-natural condition, and how it responds to natural disturbances such as fire and drought, as well as to anthropogenic disturbances such as fire exclusion and invasive species

This book presents a comprehensive overview of plant stresses caused by salt, drought, extreme temperatures, oxygen and toxic compounds, which are responsible for huge losses in crop yields. It discusses the latest research on the impact of salinity and global environment changes, and examines the advances in the identification and characterization of the mechanisms that allow plants to tolerate biotic and abiotic stresses. Further it presents our current understanding of metabolic fluxes and the various transporters that collectively open the possibility of applying in vitro technology and genetic engineering to improve stress tolerance. Exploring advanced methods that augment traditional plant tissue culture and breeding techniques toward the development of new crop varieties that can tolerate biotic and abiotic stresses to achieve sustainable food production, this book is a valuable resource for plant scientists and researchers.

Over the last decade, the field of plant ecology has significantly developed and expanded, especially in research concerning the herb layer and ground vegetation of forests. This revised second edition of The Herbaceous Layer in Forests of Eastern North America accounts for that growth, presenting research that approaches the ecology of the herb layer of forests from a variety of disciplines and perspectives. The book synthesizes the research of top ecologists and biologists on herbaceous layer structure, composition, and dynamics of a variety of forest ecosystem types in eastern North America. The 2003 first edition of The Herbaceous Layer in Forests of Eastern North America was praised for containing the most extensive listing of herb-layer literature in existence. This second edition brings this material up to date, revised to include current research and data. The book incorporates quantitative data to support analyses that was previously unavailable during the publication of the first edition. Also featured are six entirely new chapters, focused on the response of the herbaceous layer to a wide variety of natural and anthropogenic disturbances. Building on the over 1,200 references and sources of the first edition, the second edition of The Herbaceous Layer in Forests of Eastern North America is an invaluable resource for plant ecologists, forest ecologists, and conservationists.

Ecology of the Shortgrass Steppe: A Long-Term Perspective summarizes and synthesizes more than 60 years of research that has been conducted throughout the shortgrass region. The shortgrass steppe was an important focus of the International Biological Programme's Grassland Biome project that ran from the late 1960s until the mid 1970s. The work conducted by the Grassland Biome project was preceded by almost 40 years of research by U.S. Department of Agriculture researchers - primarily from the Agricultural Research Service - and followed to the present by the Shortgrass Steppe Long Term Ecological Research project. Ecology of the Shortgrass Steppe is an enormously rich source of data and insight into the structure and function of a semiarid grassland.

This book provides insight into the biology and genomics of the genus Boswellia (family Burseraceae), a natural resource used for the production of frankincense, an oleo-gum resin. The Boswellia species are ecologically, medicinally, commercially and culturally important. Significantly contributing to the paucity of comprehensive literature on this genus, this volume provides a detailed discussion on the genomics, physiology and ecology of Boswellia. The chapters cover a wide range of topics, including taxonomy, distribution, genetic diversity and microbiology. The production process of frankincense and its impact on the species are presented as well. In light of the recent decline of various Boswellia populations, species propagation and conservation are discussed. Plant scholars, ecologists and conservation biologists will find this book to be an important and informative reference.

Global change threatens ecosystems worldwide, and tropical systems with their high diversity and rapid development are of special concern. We can mitigate the impacts of change if we understand how tropical ecosystems respond to disturbance. For tropical forests and streams in Puerto Rico this book describes the impacts of, and recovery from, hurricanes, landslides, floods, droughts, and human disturbances in the Luquillo Mountains of Puerto Rico. These ecosystems recover quickly after natural disturbances, having been shaped over thousands of years by such events. Human disturbance, however, has longer-lasting impacts. Chapters are by authors with many years of experience in Puerto Rico and other tropical areas and cover the history of research in these mountains, a framework for understanding disturbance and response, the environmental setting, the disturbance regime, response to disturbance, biotic mechanisms of response, management implications, and future directions. The text provides a strong perspective on tropical ecosystem dynamics over multiple scales of time and space.

The distribution and re-distribution of people across the landscape has signi cant implications for ecological, economic and social dynamics. Movement of people to urban centres (mostly from rural landscapes, especially in the developing world) is a major global phenomenon. This can result in the de-population of rural landscapes. Conversely, population growth and a changing demographic pro le have been id- ti ed for particular rural landscapes with notable examples from North America, Europe and Australia. Yet we know little of the factors that drive demographic changes in rural landscapes and even less about the implications of these changes. This book examines broad and local-scale patterns of demographic change in rural landscapes, identi es some of the drivers of these changes using Australian case studies or comparisons between Australian and international contexts, and outlines the implications of changes for society and the environment. This book makes a valuable contribution to the literature because it adopts an integrated and interdisciplinary approach by explicitly linking demographic change with environmental, land-use, social and economic factors. This integrated approach was achieved by encouraging interaction among authors writing on similar topics to ensure coherency and complementarity among chapters, and cross-pollination of ideas and perspectives. Chapters are presented as interactive and re ective d- cussions that address the ndings of other contributors; yet, each chapter contains enough background to stand alone as a unique contribution.

The ecological sciences are a diverse array of major scientific disciplines. They grew from minor sciences, with little status in 1900, and now occupy crucial areas of research bearing on the future of our planet. This book describes a century of growth and development. A dramatic century-long rise in the status of ecological knowledge was accompanied by the rise of professional ecological organizations, the establishment of university faculties, and the creation of government agencies advising on conservation, natural resources, and the prevention of pollution. Like all sciences, ecology continues to yield new findings and surprising revelations. New technologies now address existential challenges facing our world. This book, documenting the rise of ecology, is an inspiring history portending an important role in the twenty-first century. Key Features: The author is the acknowledged authority on the history of ecology. The content is familiar to members of the Ecological Society of America but has not previously been assembled into a single narrative. Appropriate for a course in the history of ecology. Provides a broad perspective on ecology. Related Titles: Egerton, F. N. A Centennial History of the Ecological Society of America (ISBN 978-0-3673-7763-2). Rieppel, O.

Process-based models open the way to useful predictions of the future growth rate of forests and provide a means of assessing the probable effects of variations in climate and management on forest productivity. As such they have the potential to overcome the limitations of conventional forest growth and yield models, which are based on mensuration data and assume that climate and atmospheric CO2 concentrations will be the same in the future as they are now. This book discusses the basic physiological processes that determine the growth of plants, the way they are affected by environmental factors and how we can improve processes that are well-understood such as growth from leaf to stand level and productivity. A theme that runs through the book is integration to show a clear relationship between photosynthesis, respiration, plant nutrient requirements, transpiration, water relations and other factors affecting plant growth that are often looked at separately. This integrated approach will provide the most comprehensive source for process-based modelling, which is valuable to ecologists, plant physiologists, forest planners and environmental scientists.

'Succession' is the term used to describe the phenomenon of changes in vegetational types in both time and space. The subject of the colonization and exploitation of 'new' areas by plants is a key one in ecology and this book summarizes the theoretical arguments currently raging about the topic.

Human activity is producing changes to our environment on an unprecedented global scale. Learning and understanding how plants respond to these changes will be crucial to our ability to feed human populations in the future. This book gives a broad coverage of the ways in which plants respond and adjust to environmental variables, and identifies unifying concepts spanning different levels of plant organization from the subcellular to the whole natural plant community. The 18 chapters were given as invited contributions at a meeting sponsored by the Rank Prize Funds in October 1992. The book will be of great interest and use to all plant scientists and upper level students concerned with the impact of the environment on plants.

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.
