By combining the analysis of biotic and abiotic components of terrestrial ecosystems, this book synthesizes material on arid and semiarid landscapes, which was previously scattered among various books and journal articles. It focuses on water-limited ecosystems, which are highly sensitive to fluctuations in hydrologic conditions and, in turn, play an important role in affecting the regional water cycle. Intended as a tool for scientists working in the area of the earth and environmental sciences, this book presents the basic principles of eco-hydrology as well as a broad spectrum of topics and advances in this research field. Written by authors with diverse areas of expertise who work in arid areas around the world, the contributions describe the various interactions between the biological and physical dynamics in dryland ecosystems, ranging from basic processes in the soil-vegetation-climate system, to landscape-scale hydrologic and geomorphic processes, ecohydrologic controls on soil nutrient dynamics, and multiscale analyses of disturbances and patterns
Wetlands are unique and fragile environments that provide a transition between aquatic and terrestrial habitats. Focusing on freshwater wetlands with emergent vegetation, this book considers productivity in relation to communities of animals and plants and their environments, mineral cycling, hydrology, and management. The contributors emphasize the biological interactions and processes underlying the structure and functioning of wetlands, revealing the need to appreciate the dynamics of the system to establish appropriate management and conservation practices. Based largely on research carried out during the International Biological Programme, this unique synthesis brings together a wealth of information, which until now had been widely dispersed in the literature and often difficult to locate. This comprehensive volume will be an important resource for all those concerned with the ecology, management and conservation of these sensitive natural habitats.
Bryophytes were a pivotal step in land plant evolution, and their significance in the regulation of ecosystems and the conservation of biodiversity is becoming increasingly acknowledged. This introductory textbook assumes no prior knowledge of bryophyte biology, making it ideal for advanced undergraduate and graduate students, as well as amateur botanists. The authors expertly summarise the diversity of bryophytes and outline recent advances in our understanding of their evolutionary history, their ecological roles and preferences, their distribution patterns and conservation needs. The text is highly illustrated throughout, with boxed summaries of topics of current relevance in bryophyte biology, and a glossary of technical terms.
This is the first scholarly reference work to cover all the major scientific themes and facets of the subject of seeds. It outlines the latest fundamental biological knowledge about seeds, together with the principles of agricultural seed processing, storage and sowing, the food and industrial uses of seeds, and the roles of seeds in history, economies and cultures. With contributions from 110 expert authors worldwide, the editors have created 560 authoritative articles, illustrated with plentiful tables, figures, black-and-white and color photographs, suggested further reading matter and 670 supplementary definitions. The contents are alphabetically arranged and cross-referenced to connect related entries.
Plant galls may be produced by a wide variety of organisms, from fungi to parasitic insects, on an equally wide variety of hosts. Their taxonomy is highly complex, as are the life cycles of the organisms associated with them. Yet, common as they are, plant galls are often poorly understood. This book brings together information from the diverse disciplines involved in the study of plant galls: ecology, evolution, molecular biology, physiology, and developmental biology. The work considers the latest issues, covering questions of classification, coevolution, ecology, physiology, and plant genetic engineering. As an up-to-date resource in an area of immense interest and debate, the book will enhance the quality of discussion surrounding these phenomena, across all disciplinary perspectives.
Plant Strategies, Vegetation Processes, and Ecosystem Properties,
Second Edition, is a thoroughly updated and comprehensive new
edition of the very successful Plant Strategies and Vegetative
Processes, which controversially proposed the existence of
widely-recurring plant functional types with predictable
relationships to vegetation structure and dynamics.
With their team of contemporary scholars, the editors present a thorough coverage of fundamental topics necessary for obtaining an up-to-date understanding of the biology of ferns and lycophytes. The book is organized into major topics that build from the individual and its biochemistry and structure, to genetics and populations, to interactions among individuals and the conservation of species, and concludes with perspectives on evolutionary history and classification. Each chapter is organized to review past work, explore current questions, and suggest productive directions for continued discoveries about these fascinating groups of organisms. Written for upper undergraduates, graduates and academic researchers, Biology and Evolution of Ferns and Lycophytes fills a major gap in biological, organism-level, evolutionary literature by providing a review of the biology and evolution of this important group of vascular land plants.
Ecological Restoration and Management of Longleaf Pine Forests is a timely synthesis of the current understanding of the natural dynamics and processes in longleaf pine ecosystems. This book beautifully illustrates how incorporation of basic ecosystem knowledge and an understanding of socioeconomic realities shed new light on established paradigms and their application for restoration and management. Unique for its holistic ecological focus, rather than a more traditional silvicultural approach, the book highlights the importance of multi-faceted actions that robustly integrate forest and wildlife conservation at landscape scales, and merge ecological with socioeconomic objectives for effective conservation of the longleaf pine ecosystem.
Ecological biochemistry concerns the biochemistry of interactions
between animals, plants and the environment, and includes such
diverse subjects as plant adaptations to soil pollutants and the
effects of plant toxins on herbivores. The intriguing dependence of
the Monarch butterfly on its host plants is chosen as an example of
plant-animal coevolution in action.
Traditional plant physiological ecology is organism centered and
provides a useful framework for understanding the interactions
between plants and their environment and for identifying
characteristics likely to result in plant success in a particular
habitat. This book focuses on extending concepts from plant
physiological ecology as a basis for understanding carbon, energy,
and biogeochemical cycles at ecosystem, regional, and global
levels.
Taking a functional rather than an ecosystem or a utilitarian approach, Thomas and Packham provide a concise account of the structure of woodlands and forests. Using examples from around the world - from polar treelines to savannahs to tropical rain forests - the authors explain the structure of the soil and the hidden world of the roots; how the main groups of organisms which live within them interact both positively and negatively. There is particular emphasis on woodland and forest processes, especially those involving the flow and cycling of nutrients, as well as the dynamics of wooded areas, considering how and why they have changed through geological time and continue to do so. This clear, non-technical, 2007 text will be of interest to undergraduates, foresters, ecologists and land managers.
This open access book is a compilation of case studies that provide useful knowledge and lessons that derive from on-the-ground activities and contribute to policy recommendations, focusing on the relevance of social-ecological production landscapes and seascapes (SEPLS) to "transformative change." The concept of "transformative change" has been gaining more attention to deal with today's environmental and development problems, whereas both policy and scientific communities have been increasingly calling for transformative change toward sustainable society. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) has planned to start the so-called "assessment on transformative change" if approved by the IPBES plenary to be held in 2021. At present, the idea of transformative change, including its scope, methodologies, approaches and strategies, are yet to be clarified. By bringing together all of the different concerns and interests in the land/seascape, SEPLS approaches could provide practical and experience-based insights for understanding and gauging transformative change and identifying determinants of such change. This book explores how SEPLS management relates to the idea of transformative change to further the discussion of sustainable transitions in advancing sustainability science. The introductory chapter is followed by case study chapters offering real-world examples of transformative change as well as a synthesis chapter clarifying the relevance of the case study findings to policy and academic discussions. It will be of interest to scholars, policymakers and professionals in the fields related to sustainable development.
The book is designed to be a textbook for university students (MSc-PhD level) and a reference for researchers and practitioners. It is an introduction to dynamic modelling of forest growth based on ecological theory but aiming for practical applications for forest management under environmental change. It is largely based on the work and research findings of the authors, but it also covers a wide range of literature relevant to process-based forest modelling in general. The models presented in the book also serve as tools for research and can be elaborated further as new research findings emerge. The material in the book is arranged such that the student starts from basic concepts and formulations, then moves towards more advanced theories and methods, finally learning about parameter estimation, model testing, and practical application. Exercises with solutions and hands-on R-code are provided to help the student digest the concepts and become proficient with the methods. The book should be useful for both forest ecologists who want to become modellers, and for applied mathematicians who want to learn about forest ecology. The basic concepts and theory are formulated in the first four chapters, including a review of traditional descriptive forest models, basic concepts of carbon balance modelling applied to trees, and theories and models of tree and forest structure. Chapter 5 provides a synthesis in the form of a core model which is further elaborated and applied in the subsequent chapters. The more advanced theories and methods in Chapters 6 and 7 comprise aspects of competition through tree interactions, and eco-evolutionary modelling, including optimisation and game theory, a topical and fast developing area of ecological modelling under climate change. Chapters 8 and 9 are devoted to parameter estimation and model calibration, showing how empirical and process-based methods and related data sources can be bridged to provide reliable predictions. Chapter 10 demonstrates some practical applications and possible future development paths of the approach. The approach in this book is unique in that the models presented are based on ecological theory and research findings, yet sufficiently simple in structure to lend themselves readily to practical application, such as regional estimates of harvest potential, or satellite-based monitoring of growth. The applicability is also related to the objective of bridging empirical and process-based approaches through data assimilation methods that combine research-based ecological measurements with standard forestry data. Importantly, the ecological basis means that it is possible to build on the existing models to advance the approach as new research findings become available.
New or recently sterilized islands (for example through volcanic activity), provide ecologists with natural experiments in which to study colonization, development and establishment of new biological communities. Studies carried out on islands like this have provided answers to fundamental questions as to what general principles are involved in the ecology of communities and what processes underlie and maintain the basic structure of ecosystems. These studies are vital for conservation biology, especially when evolutionary processes need to be maintained in systems in order to maintain biodiversity. The major themes are how animal and plant communities establish, particularly on 'new land' or following extirpations by volcanic activity. This book comprises a broad review of island colonization, bringing together succession models and general principles, case studies with which Professor Ian Thornton was intimately involved, and a synthesis of ideas, concluding with a look to the future for similar studies.
Ecohydrology of Water-Controlled Ecosystems addresses the connections between the hydrologic cycle and plant ecosystems, with special emphasis on arid and semi-arid climates. This important topic is treated by building suitable mathematical models of the physics involved and then applying them to study the ecosystem structure and its response to rainfall and climate forcing in different parts of the world, including savannas, grasslands and forests. It investigates the vegetation response to water stress (drought), the hydrologic control on cycles of soil nutrients, and the dynamics of plant competition for water. The book also offers insights into processes closely related to soil moisture dynamics, such as soil-atmosphere interaction and soil gas emissions. This book will appeal to advanced students and researchers from a large range of disciplines, including environmental science, hydrology, ecology, earth science, civil and environmental engineering, agriculture and atmospheric science.
To gain a more complete understanding of plant-based ecological community structure requires knowledge of the integration of direct and indirect effects in plant herbivore systems. Trait modification of plants as a result of herbivory is very common and widespread in terrestrial plants, and this initiates indirect interactions between organisms that utilise the same host plant. This book argues that food webs by themselves are inadequate models for understanding ecological communities, because they ignore important indirect, nontrophic links. This subject is of great importance in understanding not only community organisation but also in identifying the underlying mechanisms of maintenance of biodiversity in nature. This book will be an invaluable resource for researchers and graduate students interested in community and population ecology, evolutionary biology, biodiversity, botany and entomology.
Tropical lichens are not only of interest in themselves but are of importance in the study of the ecosystems of which they are a part. Information on tropical lichens has not hitherto been readily available in book form, and the object of this volume is to synthesize what is known at present and to indicate areas where further research is needed. The material presented here is derived from a meeting held by the Systematics Association at which contributions were presented on the systematic, ecological, and biogeographical aspects of tropical lichens, together with the problems of their conservation. The resulting volume should thus be of value to a wide variety of scientists.
The Arctic is a special world. The Arctic Ocean is covered by white sea ice, and its margins are surrounded by bare terrestrial regions, known as tundra. Tundra is a cold and dry environment without trees, but even in the absence of trees, tundra plants such as dwarf shrubs, grasses, herbs and moss support the harsh environment by providing sustenance and shelter. This book introduces representative arctic plants and their function in Svalbard, revealing the unique tundra ecosystem, and discussing the direct and indirect effects of climate change in the Arctic.
The most respected reference in the field—and a fascinating tour of the world's largest underwater greenhouse . . . 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.
What determines the number and size of the seeds produced by a plant? How often should it reproduce them? How often should a plant produce them? Why and how are seeds dispersed, and what are the implications for the diversity and composition of vegetation? These are just some of the questions tackled in this wide-ranging review of the role of seeds in the ecology of plants. The authors bring together information on the ecological aspects of seed biology, starting with a consideration of reproductive strategies in seed plants and progressing through the life cycle, covering seed maturation, dispersal, storage in the soil, dormancy, germination, seedling establishment, and regeneration in the field. The text encompasses a wide range of concepts of general relevance to plant ecology, reflecting the central role that the study of seed ecology has played in elucidating many fundamental aspects of plant community function.
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.
This book provides insights into various aspects of medicinal plant-associated microbes, known to be a unique source of biological active compounds, including their biotechnological uses and their potential in pharmaceutical, agricultural and industrial applications. Featuring review papers and original research by leading experts in the field, it discusses medicinal plants and their interactions with the environment; medicinal plants as a source of biologically active compounds; medicinal plant-associated microbes (diversity and metabolites); their pharmaceutical, agricultural and industrial applications as well as their potential applications as plant growth stimulators and biocontrol agents. As such the book offers a valuable, up-to-date overview of the current research on medicinal plants, their ecology, biochemistry and associated biomes.
The rate of species and natural habitat loss across our planet is steadily accelerating. This book argues that existing practises of plant conservation are inadequate and firmly supports the placement of ecological restoration at the cornerstone of biodiversity conservation. The author unifies different aspects of conservation into one coherent concept, including natural area protection, ex situ conservation and in situ interventions through either population management or ecological restoration. Assisted colonization, experimentation, and utilization of threatened plant species are raised as crucial elements in restoration, with partly novel ecosystems being among its major target areas. Covering a wide spectrum of plant conservation examples, and offering practical methodologies alongside the theoretical context, this is a vital resource for students, research scientists and practitioners in conservation biology and restoration ecology.
The Environmental Biology of Agaves and Cacti constitutes the first comprehensive review of how these two interesting and economically important desert succulent taxa respond, in what turn out to be remarkably similar ways, to specific environmental factors such as water, temperature, photosynthetically active radiation, and nutrients, which affect the exchange of carbon dioxide and water vapor with the environment. Park Nobel first summarizes early environmental research as well as the many ethnobotanical uses of agaves and cacti. He then develops the main themes by considering the three most studied species in detail. Much of the relevant research has been carried out in his own laboratory since the mid-1970s. The book's clear style, many photographs and line drawings, and comprehensive data summaries make it accessible to professionals and interested laypeople alike. Every scientific term is defined the first time it is used. Agaves and cacti are shown to be highly productive compared to other plant groups, and this productivity helps account for their many uses for beverages, food, and animal fodder. Plant ecologists and physiologists, agronomists, environmental biologists, modelers, ethnobotanists, students, amateur succulent enthusiasts, and those responsible for land use and agricultural policy in arid and semiarid regions will all find this book an invaluable resource.
Dothistroma pini changed New Zealand commercial forestry dramatically. Tree breeding became concentrated on a very few species and development of selection methods and breeding strategies changed in response to the new challenges. Tree-Breeding and Genetics in New Zealand provides a critical historical account of the work on provenance research and tree breeding, often with the wisdom of hindsight, and it tracks the development of breeding strategy, especially for P. radiata, Douglas-fir and the most important eucalypt species, E. regnans, E. fastigata and E. nitens. The book is a compendium of abstracts and summaries of all publications and reports on tree improvement in New Zealand since the early 1950s, with added critical comment by the author on much of the work. It is intended for other tree breeders internationally, for interested NZ foresters and for graduate students studying genetics and tree breeding. |
