Hugh P. Possingham Landscape-scale conservation planning is coming of age. In the last couple of decades, conservation practitioners, working at all levels of governance and all spatial scales, have embraced the CARE principles of conservation planning - Comprehensiveness, Adequacy, Representativeness, and Efficiency. Hundreds of papers have been written on this theme, and several different kinds of software program have been developed and used around the world, making conservation planning based on these principles global in its reach and influence. Does this mean that all the science of conservation planning is over - that the discovery phase has been replaced by an engineering phase as we move from defining the rules to implementing them in the landscape? This book and the continuing growth in the literature suggest that the answer to this question is most definitely 'no. ' All of applied conservation can be wrapped up into a single sentence: what should be done (the action), in what place, at what time, using what mechanism, and for what outcome (the objective). It all seems pretty simple - what, where, when, how and why. However stating a problem does not mean it is easy to solve.
This book details the plant-assisted remediation method, "phytoremediation", which involves the interaction of plant roots and associated rhizospheric microorganisms for the remediation of soil contaminated with high levels of metals, pesticides, solvents, radionuclides, explosives, crude oil, organic compounds and various other contaminants. Each chapter highlights and compares the beneficial and economical alternatives of phytoremediation to currently practiced soil removal and burial practices.
This volume offers insight in the identification and selection procedure of marine protected areas in the German exclusive economic zones (EEZs) of the North - and Baltic Seas. EU Member States are obliged to establish a coherent network of protected areas, consisting of sites identified under the EC Habitats and Birds Directives. The goal of this Natura 2000 network is the conservation of biodiversity on land and in the sea. To fill important gaps in knowledge regarding the presence, abundance, and distribution of certain species and habitats in the German North- and Baltic Seas, the German Federal Agency for Nature Conservation (BfN) initiated a detailed research programme, involving researchers from many renowned German marine research institutes. This book contains the main results of the different projects under this research programme, which formed the basis for the identification and selection of the Natura 2000 sites. Information is given on two NATURA 2000 habitats (sandbanks and reefs), and benthic species, fish, birds and marine mammals, as well as on legal aspects and implementation procedures. Last but not least the book introduces the current status of NATURA 2000 in the German EEZ. Target audience are not only scientists, but also policymakers, environmental organisations and other stakeholders, and the book includes many illustrations.
Outside Russia very little is known about the terrestrial ecology, vegetation, biogeographical patterns, and biodiversity of the enormously extensive ecosystems of Yakutia, Siberia. These systems are very special in that they function on top of huge layers of permafrost and are exposed to very severe and extreme weather conditions, the range between winter and summer temperatures being more than 100 degrees C. The soils are generally poor, and human use of the vegetation is usually extensive. Main vegetation zones are taiga and tundra, but Yakutia also supports a special land and vegetation form, caused by permafrost, the alas: more or less extensive grasslands around roundish lakes in taiga. All these vegetation types will be described and their ecology and ecophysiological characteristics will be dealt with. Because of the size of Yakutia, covering several climatic zones, and its extreme position on ecological gradients, Yakutia contains very interesting biogeographical patterns, which also will be described. Our analyses are drawn from many years of research in Yakutia and from a vast body of ecological and other literature in Russian publications and in unpublished local reports. The anthropogenic influence on the ecosystems will be dealt with. This includes the main activities of human interference with nature: forestry, extensive reindeer herding, cattle and horse grazing, etc. Also fire and other prominent ecological factors are dealt with. A very important point is also the very high degree of naturalness that is still extant in Yakutia's main vegetation zones.
This book provides an up-to-date analysis of the Portuguese forests and forestry sector, including its history, its total economic value, current threats and opportunities and future challenges, namely the need to incorporate more planning and technology in forest management practices. The methodological approach of analysing the forestry sector in terms of its total economic value, and the use of this new perspective to correctly perceive the forest sector and to base development strategies is unique. Also, the use of new methods and technologies in the Portuguese forestry sector will be an opportunity to share these experiences with a wider international audience. For example, fire incidence during the summer has almost no parallel in the Western World, implying that Portuguese forest landscapes function as a "natural lab of wildfires" from which much can be learned globally. Thus, the outcomes of the fire management policies adopted might represent important lessons for Mediterranean basin countries.
Combining an ecosystems approach with new insights at the molecular and biochemical level, this book presents the latest findings on how plants respond, physiologically, to sulfur in their environment. It explores key areas - such as biotic and abiotic interactions, adaptations to fluctuating supply, and sulfur's role in plant metabolic networks - to assess the functions and implications of this essential plant nutrient in a range of natural, semi-natural and anthropogenic environments.Leaders in the field, Hawkesford and de Kok, draw together an international group of experts in plant sulfur nutrition, to collate and integrate new information from molecular biology, ecology and physiology. The result is an important new reference on the relationships between plants and sulfur at all levels - including contributions arising from recent omic' approaches.
In Loe Bar and the Sandhill Rustic Moth, Adrian Spalding examines the survival of plants and animals on Loe Bar, a shingle beach on the coast of Cornwall, in the context of its history, geomorphology and exposure to the Atlantic environment. He develops these themes within a detailed study of the Sandhill Rustic moth that endures this harsh environment where storm surges, high salinity, high temperatures, strong winds and burial by sand affect the wildlife that occurs there.
Phytoplasma III is the last of three books in the series covering all the aspects of phytoplasma-associated diseases. Phytoplasmas are a major limiting factor in the quality and productivity of many ornamental, horticultural and economically important agriculture crops worldwide, and losses due to phytoplasma diseases have disastrous consequences for farming communities. As there is no effective cure for these diseases, management strategies focus-on exclusion, minimizing their spread by insect vectors and propagation materials, and developing host plant resistance. This book provides an update on genomics, effectors and pathogenicity factors toward a better understanding of phytoplasma-host metabolic interactions. It offers a comprehensive overview of biological, serological and molecular characterization of the phytoplasmas, including recently developed approaches in diagnostics, such as transcriptomics studies, which have paved the way for analyzing the gene expression pattern in phytoplasmas on infection and revealed the up-regulation of genes associated with hormonal response, transcription factors, and signaling genes. Although phytoplasmas remain the most poorly characterized pathogens, recent studies have identified virulence factors that induce typical disease symptoms and have characterized the unique reductive evolution of the genome. Reviewing the advances in cultivation in axenic media together with the perspectives for future research to reduce the global incidence of these pathogens and the associated agricultural losses, the book is a valuable resource for plant pathologists, researchers in agriculture and PhD students.
A multiplicity of biotrophic micro-organisms interact with plants in nature, forming symbiotic relationships that range from mutualism to antagonism. Microorganisms that have adopted biotrophy as a lifestyle are able to colonize the plant and often to cross the plant cell boundaries by forming intracellular structures that are the site of nutrient uptake/exchange. To establish themselves within plant tissues, both mutualistic and pathogenic biotrophs need to overcome the plant defense response through an exchange of molecular signals. Our knowledge of the nature of these signals and their function in the interaction has rapidly increased over the last few years. This volume focuses on the genetic, molecular and cellular components involved in the communication between partners of well-known symbioses, but also reports on the advances for less studied systems.
Plant dormancy involves synchronization of environmental cues with developmental processes to ensure plant survival; however, negative impacts of plant dormancy include pre-harvest sprouting, non-uniform germination of crop and weed seeds, and fruit loss due to inappropriate bud break. Thus, our continued quest to disseminate information is important in moving our understanding of plant dormancy forward and to develop new ideas for improving food, feed, and fiber production and efficient weed control, particularly under global climate change. Proceeding from the 5th International Plant Dormancy Symposium will provide an overview related on our current understanding of how environmental factors impact cellular, molecular, and physiological processes involved in bud and seed dormancy, and perspectives and/or reviews on achievements, which should stimulate new ideas and lines of investigation that increase our understanding of plant dormancy and highlight directions for future research.
Undeservedly out of print for decades, American Plants for American Gardens was one of the first popular books to promote the use of plant ecology and native plants in gardening and landscaping. Emphasizing the strong links between ecology and aesthetics, nature and design, the book demonstrates the basic, practical application of ecological principles to the selection of plant groups or "associations" that are inherently suited to a particular climate, soil, topography, and lighting. Specifically, American Plants for American Gardens focuses on the vegetation concentrated in the northeastern United States, but which extends from the Atlantic Ocean west to the Alleghenies and south to Georgia. The plant community settings featured include the open field, hillside, wood and grove, streamside, ravine, pond, bog, and seaside. Plant lists and accompanying texts provide valuable information for the design and management of a wide range of project types: residential properties, school grounds, corporate office sites, roadways, and parks. In his introduction, Darrel G. Morrison locates American Plants for American Gardens among a handful of influential early books advocating the protection and use of native plants--a major area of interest today among serious gardeners, landscape architects, nursery managers, and students of ecology, botany, and landscape design. Included is an appendix of plant name changes that have occurred since the book's original publication in 1929. Ahead of their time in many ways, Edith A. Roberts and Elsa Rehmann can now speak to new generations of ecologically conscious Americans.
This book presents studies on current vegetation topics, from polar to tropical regions. It is a festschrift to mark the 70th birthday of Prof. Elgene O. Box, who has studied vegetation all over the world, both through fieldwork and modeling. It reflects a number of his interests, including basic ecological plant forms (cf 'plant functional types'), temperate-zone forests, and evergreen versus seasonal patterns. Section 1 discusses the concept of vegetation series, while Section 2 has two global-scale chapters on plant functional traits and whether they are related more to climate or phylogeny. Section 3 has nine chapters focusing on vegetation history, regional vegetation, and how these have influenced current species organizations and distributions. Regions treated include Russia, China, the USA, Mexico and Mediterranean areas. Lastly, Section 4 addresses aspects of vegetation change and plant ecology. Every chapter in this unique book offers original ideas on the topic of vegetation, as the authors are assembled from a world-wide population of leading vegetational ecologists, whose interests range from local communities to global theoretical questions.
This volume is a cogent empirical analysis of the interplay between a region's natural amenities and its socioeconomic evolution. It focuses on the rural sectors of America's Intermountain West region, which lies between the Cascades and Sierra Nevada mountains to the west and the Rocky Mountains to the east. Coherently structured and meticulously detailed, it adds much to our understanding of the ways an area's forests, lakes, mountains, parkland and historic attractions affect residents' sense of well-being as well as the sociodemographic and economic changes they experience. The book examines patterns of growth and change linked to the emergence of 'New West' conditions, assessing their implications for the wider community as well as discussing the impact these trends could have on the consumption of natural resources. It also points to ways in which communities and their development can be managed sustainably. The tight geographical focus of this valuable resource ensures a depth of analysis which can be applied to similar regions worldwide. Based on a large-scale, random-sample survey of both full-time and seasonal residents, it provides a much-needed overview of the macro-level economic, demographic, and social transformations affecting rural communities in America. As such, the book has relevance for all researchers concerned with rural development, the changes impacting rural landscapes, and natural resource management.
Climate change, urban sprawl, abandonment of agriculture, intensification of forestry and agriculture, changes in energy generation and use, expansion of infrastructure networks, habitat destruction and degradation, and other drivers of change occur at increasing rates. They affect patterns and processes in forest landscapes, and modify ecosystem services derived from those ecosystems. Consequently, rapidly changing landscapes present many new challenges to scientists and managers. While it is not uncommon to encounter the terms "global change" and "landscape" together in the ecological literature, a global analyses of drivers of change in forest landscapes, and their ecological consequences have not been addressed adequately. That is the goal of this volume: an exploration of the state of knowledge of global changes in forested landscapes with emphasis on causes and effects, and challenges faced by researchers and land managers. Initial chapters identify and describe major agents of landscape change: climate, fire, and human activities. The next series of chapters address implications of changes on ecosystem services, biodiversity conservation and carbon flux. A chapter that describes methodologies of detecting and monitoring landscape changes is presented followed by chapter that highlights the many challenges forest landscape managers face amidst of global change. Finally, we present a summary and a synthesis of the main points presented in the book. Each chapter will contain the individual research experiences of chapter authors, augmented by review and synthesis of global scientific literature on relevant topics, as well as critical input from multiple peer reviewers.
During the last ten years, knowledge about the multitude of adaptive responses of plants to low oxygen stress has grown immensely. The oxygen sensor mechanism has been discovered, the knowledge about the interaction network of gene expression is expanding and metabolic adaptations have been described in detail. Furthermore, morphological changes were investigated and the regulative mechanisms triggered by plant hormones or reactive oxygen species have been revealed. This book provides a broad overview of all these aspects of low oxygen stress in plants. It integrates knowledge from different disciplines such as molecular biology, biochemistry, ecophysiology and agricultural / horticultural sciences to comprehensively describe how plants cope with low oxygen stress and discuss its ecological and agronomical consequences. This book is written for plant scientists, biochemists and scientists in agriculture and ecophysiology.
Soil organic carbon (SOC), a key component of the global carbon (C) pool, plays an important role in C cycling, regulating climate, water supplies and biodiversity, and therefore in providing the ecosystem services that are essential to human well-being. Most agricultural soils in temperate regions have now lost as much as 60% of their SOC, and as much as 75% in tropical regions, due to conversion from natural ecosystems to agricultural uses and mainly due to continuous soil degradation. Sequestering C can help to offset C emissions from fossil fuel combustion and other C-emitting activities, while also enhancing soil quality and long-term agronomic productivity. However, developing effective policies for creating terrestrial C sinks is a serious challenge in tropical and subtropical soils, due to the high average annual temperatures in these regions. It can be accomplished by implementing improved land management practices that add substantial amounts of biomass to soil, cause minimal soil disturbance, conserve soil and water, improve soil structure, and enhance soil fauna activity. Continuous no-till crop production is arguably the best example. These soils need technically sound and economically feasible strategies to sustainably enhance their SOC pools. Hence, this book provides comprehensive information on SOC and its management in different land-use systems, with a focus on preserving soils and their ecosystem services. The only book of its kind, it offers a valuable asset for students, researchers, policymakers and other stakeholders involved in the sustainable development and management of natural resources at the global level.
The fundamental problem the world faces today, is the rapidly increasing pressure of population on the limited resources of the land. To meet the ever increasing demands of expanding populations, agricultural production has been raised through the abundant use of inorganic fertilizers, the adoption of multicropping systems and liberal application of chemical pesticides (fungicides, bactericides, etc. ). Though the use of chemicals has increased the yield dramatically, it has also resulted in the rapid deterioration of land and water resources apart from wastage of scarce resources. This has adversely affected the biological balance and lead to the presence of toxic residues in food, soil and water in addition to imposing economic constraints on developing countries.' (From the Preface) Mycorrhizal Biology addresses the global problem of land degradation and the associated loss of soil productivity and decline in soil quality caused by exploitative farming practices and poor management in developing countries, and the far reaching socio-economic and ecological consequences of its impact on agricultural productivity and the environment. In the light of a need for sustainable development, a new system of productive agriculture, to ensure the efficient management of agricultural inputs for long term high crop productivity with minimum damage to the ecological and socio-economic environment is essential. The management of mycorrhizal fungi will form a significant part of such a system and this work investigates the key association of plant roots with mycorrhizal fungi, known to benefit plants under conditions of nutritional and water stress and pathogen challenge and analyses thedevelopments in our understanding of the genetic loci that govern mycorrhiza formation.
In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study.This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.
This book is the first comprehensive global review of all aspects of alien plant invasions in protected areas. It provides insights into advances in invasion ecology emanating from work in protected areas, and the link to locally relevant management support for protected areas. The book provides in-depth case studies, illuminating interesting and insightful knowledge that can be shared across the global protected area network. The book includes the collective understanding of 80 ecologists and managers to extract as much information as possible that will support the long-term management of protected areas, and the biodiversity and associated ecosystem services they maintain. " This outstanding volume draws together pretty much all that can be said on this topic, ranging from the science, through policy, to practical action ." Dr. Simon N. Stuart, IUCN Species Survival Commission, UK. ""This important and timely volume addresses two of the most serious problems affecting biodiversity conservation today: assessing the extent to which protected areas are impacted by biological invasions and the complex problems of managing these impacts. Written by leading specialists, it provides a comprehensive overview of the issues and gives detailed examples drawn from protected areas across the world."" Professor Vernon H. Heywood, School of Biological Sciences, University of Reading, UK "
Due to many issues related to long-term carbon dynamics, an improved understanding of the biology of C4 photosynthesis is required by more than the traditional audience of crop scientists, plant physiologists, and plant ecologists. This work synthesizes the latest developments in C4 biochemistry, physiology, systematics, and ecology. The book concludes with chapters discussing the role of C4 plants in the future development of the biosphere, particularly their interactive effects on soil, hydrological, and atmospheric processes.
This book presents advanced ecological techniques for crop cultivation and the chapters are arranged into four sections, namely general aspects, weeds, fungi, worms and microbes. Biocontrol is an ecological method of controlling pests such as insects, mites, weeds and plant diseases using other organisms. This practice has been used for centuries. Biocontrol relies on predation, parasitism, herbivory, or other natural mechanisms. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors.
Most organisms and populations have to cope with hostile environments, threatening their existence. Their ability to respond phenotypically and genetically to these challenges and to evolve adaptive mechanisms is, therefore, crucial. The contributions to this book aim at understanding, from a evolutionary perspective, the impact of stress on biological systems. Scientists, applying different approaches spanning from the molecular and the protein level to individuals, populations and ecosystems, explore how organisms adapt to extreme environments, how stress changes genetic structure and affects life histories, how organisms cope with thermal stress through acclimation, and how environmental and genetic stress induce fluctuating asymmetry, shape selection pressure and cause extinction of populations. Finally, it discusses the role of stress in evolutionary change, from stress induced mutations and selection to speciation and evolution at the geological time scale. The book contains reviews and novel scientific results on the subject. It will be of interest to both researchers and graduate students and may serve as a text for graduate courses.
This book provides a comprehensive overview of the multiple strategies that plants have developed to cope with drought, one of the most severe environmental stresses.
