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.

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.

This thoroughly revised and updated edition provides an accessible overview of the rapidly advancing field of plant physiology. Key topics covered include absorption of water, ascent of sap, transpiration, mineral nutrition, fat metabolism, enzymes and plant hormones. Separate chapters are included on photosynthesis, respiration and nitrogen metabolism, and emphasis is placed on their contribution to food security, climate resilient farming (or climate-smart agriculture) and sustainable development. There is also a chapter on the seminal contributions of plant physiologists. Supported by the inclusion of laboratory experimental exercises and solved numerical problems, the text emphasises the conceptual framework, for example, in coverage of topics such as thermodynamics, water potential gradients and energy transformation during metabolic processes, water use efficiency (WUE) and nitrogen use efficiency (NUE). Bringing together the theoretical and practical details, this text is accessible, self-contained and student-friendly.

The multitrophic level approach to ecology addresses the complexity of food webs much more realistically than the traditional focus on simple systems and interactions. Only in the last twenty years have ecologists become interested in the nature of more complex systems including tritrophic interactions between plants, herbivores, and natural enemies. These interactions are explored in this exciting new volume by expert researchers from a variety of ecological fields. This book provides a much-needed synthesis of multitrophic level interactions and serves as a guide for future research for ecologists of all descriptions.

Lee Frelich provides a major contribution to the study of temperate-zone forest dynamics by considering three important themes: the combined influence of wind, fire, and herbivory on the successional trajectories and structural characteristics of forests; the interaction of deciduous and evergreen tree species to form mosiacs; and the significance of temporal and spatial scale with regard to the overall impact of disturbances. These themes are explored via case studies from the forests in the Lake States of Minnesota, Wisconsin and Michigan, where the presence of large primary forest remnants provides a unique opportunity to study the long-term dynamics of near-boreal, pine, and hardwood-hemlock forests.

Disturbance ecology continues to be an active area of research, having undergone advances in many areas in recent years. One emerging direction is the increased coupling of physical and ecological processes, in which disturbances are increasingly traced back to mechanisms that cause the disturbances themselves, such as earth surface processes, mesoscale, and larger meteorological processes, and the ecological effects of interest are increasingly physiological. Plant Disturbance Ecology, 2nd Edition encourages movement away from the informal, conceptual approach traditionally used in defining natural disturbances and clearly presents how scientists can use a multitude of approaches in plant disturbance ecology. This edition includes nine revised chapters from the first edition, as well new, more comprehensive chapters on fire disturbance and beaver disturbance. Edited by leading experts in the field, Plant Disturbance Ecology, 2nd Edition is an essential resource for scientists interested in understanding plant disturbance and ecological processes.

The predictability of the physical arrangement of plants, at whatever scale it is viewed, is referred to as a spatial pattern. Spatial pattern is a crucial aspect of vegetation that has important implications not only for the plants themselves, but also for other organisms that interact with plants, such as herbivores and pollinators; or those animals for which plants provide a habitat. This book describes and evaluates methods for detecting and quantifying a variety of characteristics of spatial pattern. As well as discussing the concepts on which these techniques are based, the book includes examples from real field studies and worked examples, which, together with numerous line figures, help guide the reader through the text.

Pinus is a remarkable genus of trees with a very large distribution range in the northern hemisphere. Where they occur, pines usually form the dominant vegetation cover and are extremely important components of ecosystems. They also provide a wide range of products for human use. In many cases exploitation and other human pressures are threatening the survival of natural pine forests, although pines are also widely grown in commercial plantations, both within and outside their natural range. This book presents a definitive review of pine ecology and biogeography written by forty of the world's leading authorities on this important genus. In the face of increasing human pressure and global climate change, it provides an essential source of reference for all those concerned with the management of natural and planted pine forests.

This new edition is a major contribution to botanical and ecological literature.

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.

Grasses occupy a greater area of the world's land surface than any other plant family, occurring in almost every terrestrial environment and providing a vital source of food for humans and animals. This volume presents the most recent information on their population biology, bringing together contributions from researchers studying both applied and fundamental aspects of this important group of plants. This volume considers demographic, physiological, ecological and molecular approaches to understanding grass populations in relation to reproduction and to aspects of life history patterns such as dispersal, germination, seedling establishment, population dynamics and reproduction. Other areas covered include the role of genetic variation and phenotypic plasticity in shaping life history traits, the impact of biotic factors, and the ecology of specific species in major grass-dominated ecosystems in Africa, Australia and Japan.

Plant Life under Changing Environment: Responses and Management presents the latest insights, reflecting the significant progress that has been made in understanding plant responses to various changing environmental impacts, as well as strategies for alleviating their adverse effects, including abiotic stresses. Growing from a focus on plants and their ability to respond, adapt, and survive, Plant Life under Changing Environment: Responses and Management addresses options for mitigating those responses to ensure maximum health and growth. Researchers and advanced students in environmental sciences, plant ecophysiology, biochemistry, molecular biology, nano-pollution climate change, and soil pollution will find this an important foundational resource.

This book reexamines patterns of relationship among plant life history traits in phylogenetic perspective. The reexamination first recognizes that because evolution is a branching process, traits are not randomly distributed across taxa and that therefore analysis of trait correlations cannot treat species as independent data points. It then discusses the use of phylogeny to reconstruct the evolutionary pathways of traits. Part 1 looks at the use of the phylogenetic perspective on trait correlation. Parts 2-4 examine traits from the reproductive phase from seed production and dispersal to recruitment and growth. The final section looks at interactions between plants and competitors, herbivores and microbial symbionts, recognizing that these interactions may have an ancient evolutionary history.

Phytoremediation Potential of Perennial Grasses provides readers with the knowledge to select specific perennial grass species according to site-specific needs. In addition, it demonstrates the potential opportunities for grass-based phytoremediation to yield phytoproducts, especially biomass-based bioenergy and aromatic essential oils as a green economy while in the process of remediating contaminated sites. The book brings together recent and established knowledge on different aspects of grass-based phytoremediation, providing this information in a single source that offers a cutting-edge synthesis of scientific and experiential knowledge on polluted site restoration that is useful for both practitioners and scientists in environmental science and ecology.

Destruction of tropical rain forests has increased exponentially in recent years, as have efforts to conserve them. However, information essential to these conservation programs--an understanding of the population dynamics of the community at risk--is often unavailable to the scientists and resource managers who need it most.
This volume helps fill the gap by presenting a comprehensive description and analysis of the animal community of the tropical rain forest at El Verde, Puerto Rico. Building on more than a decade of field research, the contributors weave the complex strands of information about the energy flow within the forest--who eats whom--into a powerful tool for understanding community dynamics known as a food web. This systematic approach to organizing the natural histories of the many species at El Verde also reveals basic patterns and processes common to all rain forests, making this book a valuable contribution for anyone concerned with studying and protecting these fragile ecosystems.

Grasses are put to a multitude of uses by those involved in agriculture and recreation. They are also of importance to environmental biologists; for example those involved in restorative ecology. In this book the biology of grasses is illustrated and elucidated through the use of many different grass genera and species, drawn from both temperate and tropical zones. Beginning with a discussion of the role of grasses in a changing world, the author provides a thorough treatment of such topics as the generation and dispersal of grasses, their diversity, history, contrasting life styles, ecology and domestication. The text is supported by the inclusion of high quality line drawings and black and white photographs. There is also a thorough glossary of the terminology associated with grass science. This book bridges the gap between introductory textbooks and research and technical papers. It is an advanced level reference text for students and teachers of agriculture, plant biology and ecology. It is of particular importance to all those studying the genetics, physiology and taxonomy of grasses.

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

Forces of nature and human intervention lead to innumerable local, regional and sometimes global changes in plant community patterns. Regardless of the causes and the intensity of change, ecosystems are often naturally able to recover most of their attributes through natural succession. In this thoughtful and provocative new book, Fakhri Bazzaz integrates and synthesizes information on how disturbance changes the environment, how species function, coexist, and share or compete for resources in populations and communities, and how species replace each other over successional time. It illustrates how a diverse array of plant species have been used to examine fundamental questions in plant ecology by integrating physiological, population and community ecology. Graduate students and research workers in plant ecology, global change, conservation and restoration will find the perspective and analysis offered by this book an exciting contribution to the development of our understanding of plant successional change.

The rain forests of tropical America, Africa, Asia, and Australia are rapidly vanishing. With a focus on ecology, this book discusses rain forests as complex natural systems that are continually changing in response to climate and soil conditions, as well as to shifting cultivation, logging, and other human activities. The completely revised edition includes new chapters on climate (contributed by R.P.D. Walsh), microclimates and hydrology (contributed by R.P.D. Walsh), soils (contributed by I.C. Baillie) and an appendix on quantitative methods (contributed by P. Greig-Smith). This book, first published in 1952, is now a classic and represents an important record of what has become of the rain forest in the twentieth century and will be meaningful reading for botanists, ecologists, tropical biologists, conservationists, and general readers.

It is almost dogma that the boreal forest in North America is a fire-dependent forest, yet ecologists often do not consider in any technical detail how forest fires produce effects on individual plants and on plant populations. Consequently, the causal connection between the behaviour of fire and its ecological consequences is poorly understood. This book sets out to correct this deficiency by assembling the relevant studies of fire intensity, rate of spread, fuel consumption, fire frequency and fire weather in the North American boreal forest. The central thesis is that the North American boreal forest has at least four wildfire characteristics that are important in understanding the dynamics of its plant populations: the large size of the burns with respect to dispersal distances, the short recurrence time of fire with respect to tree lifespans, the high mortality of plants due to the predominance of crown fires, and a good germination surface due to the large area of the forest floor which is covered by ash.

An appreciation of the natural processes of woodlands is essential for the development of a rationale and practices for woodland nature conservation and management. In this book, Dr. Peterken describes how woodlands grow, die, and regenerate in the absence of human influence, and the structures and range of habitats found in natural woods. He describes examples of virgin and old-growth forests in Europe and North America, and outlines the dynamics and structure of natural temperate woodlands. This knowledge is then applied to nature conservation issues in British woods and forests, particularly the maintenance of "untouched" reserves, the management of native broadleaved woods, and the design of coniferous plantations. Natural Woodlands is a fascinating account of woodland natural history for all those concerned with the management and ecology of natural or commercial woodlands.

What are the ecological attributes of weeds that confer the ability to interfere with human activities? Roger Cousens and Martin Mortimer place weed management within an ecological context, with the focus on the manipulation of population size. The dynamics of abundance and spatial distribution are considered at both geographic and local scales. The basic processes of dispersal, reproduction and mortality are described, together with the factors that influence them. Management is shown to modify patterns of behaviour that are intrinsic to populations. Attention is given to the evolution and management of resistance to herbicides. This book provides weed science with the conceptual basis that has previously been lacking. It also gives ecologists access to the extensive database on the population ecology of weeds.
