The Systems Ecology Paradigm (SEP) incorporates humans as integral parts of ecosystems and emphasizes issues that have significant societal relevance such as grazing land, forestland, and agricultural ecosystem management, biodiversity and global change impacts. Accomplishing this societally relevant research requires cutting-edge basic and applied research. This book focuses on environmental and natural resource challenges confronting local to global societies for which the SEP methodology must be utilized for resolution. Key elements of SEP are a holistic perspective of ecological/social systems, systems thinking, and the ecosystem approach applied to real world, complex environmental and natural resource problems. The SEP and ecosystem approaches force scientific emphasis to be placed on collaborations with social scientists and behavioral, learning, and marketing professionals. The SEP has given environmental scientists, decision makers, citizen stakeholders, and land and water managers a powerful set of tools to analyse, integrate knowledge, and propose adoption of solutions to important local to global problems.
This volume summarizes current research on the influence of plant polyphenols on human health, promoting collaboration between chemists and biologists to improve our understanding of their biological significance, and expanding the possibilities for their use.

over three hundred newly located, preserved, or restored sites, the
second edition is the prairie enthusiast's ideal guide to locating
countless North American sites-from the well-documented to the
remote. Readers can use the guide to plan both convenient visits to
close-to-home prairies and journeys to sites well across the
continent. Also included is an expanded state-by-state index, ideal
for locating specific prairies in any given state.
Plant remains can preserve a critical part of history of life on Earth. While telling the fascinating evolutionary story of plants and vegetation across the last 500 million years, this book also crucially offers non-specialists a practical guide to studying, dealing with and interpreting plant fossils. It shows how various techniques can be used to reveal the secrets of plant fossils and how to identify common types, such as compressions and impressions. Incorporating the concepts of evolutionary floras, this second edition includes revised data on all main plant groups, the latest approaches to naming plant fossils using fossil-taxa and techniques such as tomography. With extensive illustrations of plant fossils and living plants, the book encourages readers to think of fossils as once-living organisms. It is written for students on introductory or intermediate courses in palaeobotany, palaeontology, plant evolutionary biology and plant science, and for amateurs interested in studying plant fossils.
Ecology and economics have Greek roots in oikos for "household," logos for "study," and nomics for "management." Thus, ecology and economics should have complemented one another for a proper growth and development without destruction, but, unfortunately, rapid industrialization, lure for fast financial gains, and commercialization activities have led to a widespread surge in pollution load, environmental degradation, habitat destruction, rapid loss ofbiodiversity, sudden rise in rate ofextinction ofmany wildlife and wild relatives of domesticated animals and cultivated cereals and other plants, global climate changes creating global rise in temperature, and CO levels and increased ultraviolet B at ground 2 level. Although these threats to human health have led us to look to ecology for their solutions and guidance for sustainable development without destruction, the industrial and technology houses are looking for alternative methods of development and resource use methods. The two global conferences of the United Nations in 1972 and 1992, and international programs of Man and the Biosphere (MAB), International Biological Program (IBP), International Geosphere, Biosphere program (lGBP), and World Conser vation Union (IUCN), of different commissions, United Nations Environmental Program (UNEP) efforts, Ramsar Conventions (for wetlands), and World Wide fund for Nature (WWF) (for nature in general and wildlife in particular) have focused attention of ecologists, naturalists, governments and Non-governmental organizations (NGOs) toward better conservation."
Model development is of vital importance for understanding and management of ecological processes. Identifying the complex relationships between ecological patterns and processes is a crucial task. Ecological modelling-both qualitatively and quantitatively-plays a vital role in analysing ecological phenomena and for ecological theory. This textbook provides a unique overview of modelling approaches. Representing the state-of-the-art in modern ecology, it shows how to construct and work with various different model types. It introduces the background of each approach and its application in ecology. Differential equations, matrix approaches, individual-based models and many other relevant modelling techniques are explained and demonstrated with their use. The authors provide links to software tools and course materials. With chapters written by leading specialists, "Modelling Complex Ecological Dynamics" is an essential contribution to expand the qualification of students, teachers and scientists alike.
Plant leaves collectively represent the largest above-ground surface area of plant material in virtually all environments. Their optical properties determine where and how energy and gas exchange occurs, which in turn drives the energy budget of the planet, and defines its ecology and habitability. This book reviews the state-of-the-art research on leaf optics. Topics covered include leaf traits, the anatomy and structure of leaves, leaf colour, biophysics and spectroscopy, radiometry, radiative transfer models, and remote and proximal sensing. A physical approach is emphasised throughout, providing the necessary foundations in physics, chemistry and biology to make the context accessible to readers from various subject backgrounds. It is a valuable resource for advanced students, researchers and government agency practitioners in remote sensing, plant physiology, ecology, resource management and conservation.
This book represents the authors' lifetime dedication to the study of inhibitors and phytohormones as well as its practical applications for achieving a more sustainable agriculture. Their work focuses on the functions of various groups of active molecules, their direct effect upon plant growth, but also implications for their impact upon the surrounding environment are explored. The main idea of the book evolved from the need to determine a balance among natural growth inhibitors and phytohormones. This approach was pursued through a better understanding of their biochemical pathways, their effects on plants physiological functions, and their influence upon stress factors on plant ontogenesis. Therefore, this effort proposes a more holistic approach to the study of plant physiology, in which the plant-soil interactions are discussed, with a profound description of different allelochemicals and their effects on plants growth. A rigorous attention is also paid to discuss the role of microorganisms in ecosystems and their capability to synthesize physiologically active substances, which trigger also unique plant-microbial interactions. These synergies are leading scientists to the discovery of major breakthroughs in agriculture and pharmacology that are revolutionizing old epistemologies and thus, contributing to the emergence of a philosophy of interconnectedness for the whole biosphere.
The National Botanical Research Institute came into being as the 13th among a chain of National Laboratories established during April, 1953 under the Council of Scientific and Industrial Research by the Govt. of India for advanced research in fields of specialisation which have a direct bearing on socio-economic, industrial and scientific advancement of the nation. Christened initially as National Botanic Gardens, the nucleus around which the institution took shape under its founder- Director Late Prof. K. N. Kaul, was a large herbarium of Indian flora and a centu- old botanical garden spread over 35 ha of land on the banks of River Gomti in the heart of Lucknow city. It's a matter of great pleasure and profound satisfaction to me that a Golden Jubilee volume entitled, "Pteridology in the New Millennium" is being published and released during the Golden Jubilee year of NBRI in the honour of Professor B. K. Nayar who laid the foundation of the Pteridology Laboratory of the NBRI, which is now a well equipped laboratory for the study of Indian pteridophytes. Professor Nayar is a holistic Botanist as evident through his contributions and publications in almost all the areas of study of Pteridophyta. The contribution of Professor Nayar towards the development of modern Pteridology and the role of NBRI in it is indeed great and very important. His publications will be valuable for the younger generation of scientists in the field as well as for the more mature research workers and teachers.
Plant Production in Closed Ecosystems provides overviews of the current trends and concepts in plant production in closed or semi-closed environments. The overviews reflect both the present and future challenges that face the agricultural industry and the methods and tools which will meet these challenges. Plant Production in Closed Ecosystems contains the full texts of the Special Lectures from the International Symposium on Plant Production in Closed Ecosystems, plus several contributed papers. The challenges which await the agricultural industry are diverse. This diversity is reflected in the topics that were covered in the special lectures given by experts in the field. These topics included: greenhouse horticulture, hydroponics, micropropagation, food production in space, environmental control, co-generation, controlled ecological life support systems (CELSS), and resource conservation.
This multidisciplinary book covers all aspects of planning, designing, establishing and managing forests and trees and forests in and near urban areas, with chapters by experts in forestry, horticulture, landscape ecology, landscape architecture and even plant pathology. Beginning with historical and conceptual basics, the coverage includes policy, design, implementation and management of forestry for urban populations.
This textbook covers Plant Ecology from the molecular to the global level. It covers the following areas in unprecedented breadth and depth: - Molecular ecophysiology (stress physiology: light,
temperature, oxygen deficiency, drought, salt, heavy metals,
xenobiotica and biotic stress factors) The book is carefully structured and well written: complex
issues are elegantly presented and easily understandable. It
contains more than 500 photographs and drawings, mostly in colour,
illustrating the fascinating subject.
How do plants make a living? Some plants are gamblers, others are swindlers. Some plants are habitual spenders while others are strugglers and miserly savers. Plants have evolved a spectacular array of solutions to the existential problems of survival and reproduction in a world where resources are scarce, disturbances can be deadly, and competition is cut-throat. Few topics have both captured the imagination and furrowed the brows of plant ecologists, yet no topic is more important for understanding the assembly of plant communities, predicting plant responses to global change, and enhancing the restoration of our rapidly degrading biosphere. The vast array of plant strategy models that characterize the discipline now require synthesis. These models tend to emphasize either life history strategies based on demography, or functional strategies based on ecophysiology. Indeed, this disciplinary divide between demography and physiology runs deep and continues to this today. The goal of this accessible book is to articulate a coherent framework that unifies life history theory with comparative functional ecology to advance prediction in plant ecology. Armed with a deeper understanding of the dimensionality of life history and functional traits, we are now equipped to quantitively link phenotypes to population growth rates across gradients of resource availability and disturbance regimes. Predicting how species respond to global change is perhaps the most important challenge of our time. A robust framework for plant strategy theory will advance this research agenda by testing the generality of traits for predicting population dynamics.
This book is unique in providing a global overview of alpine (high
mountain) habitats that occur above the natural (cold-limited) tree
line, describing the factors that have shaped them over both
ecological and evolutionary timescales. The broad geographic
coverage helps synthesize common features whilst revealing
differences in the world's major alpine systems from the Arctic to
the Tropics. The words "barren" and "wasteland" have often been
applied to describe landscapes beyond the tree line. However, a
closer look reveals a large diversity of habitats, assemblages and
individual taxa in the alpine zone, largely connected to
topographic diversity within individual alpine regions.
Is it possible to omit parasites when studying free-living
organisms? The answer is clearly no! Parasites have evolved
independently in numerous animal lineages, and now make up a
considerable proportion of the biodiversity of life. Ecologists,
epidemiologists, conservationists and evolutionary biologists are
increasingly aware of the universal significance of parasites to
the study of ecology and evolution where they have become a
powerful model system. This book provides a summary of the issues
involved as well as an overview of the possibilities offered by
this research topic including the practical applications for
disease prevention. It uses well-documented case-studies across a
range of scales to illustrate the main trends and prospects in this
area, outlining areas for future research.
This book addresses an important problem in ecology: how are communities assembled from species pools? This pressing question underlies a broad array of practical problems in ecology and environmental science, including restoration of damaged landscapes, management of protected areas, and protection of threatened species. This book presents a simple logical structure for ecological assembly and addresses key areas including species pools, traits, environmental filters, and functional groups. It demonstrates the use of two predictive models (CATS and Traitspace) and consists of many wide-ranging examples including plants in deserts, wetlands, and forests, and communities of fish, amphibians, birds, mammals, and fungi. Global in scope, this volume ranges from the arid lands of North Africa, to forests in the Himalayas, to Amazonian floodplains. There is a strong focus on applications, particularly the twin challenges of conserving biodiversity and understanding community responses to climate change.
Fundamental Processes in Ecology presents a way to study ecosystems
that is not yet available in ecology textbooks but is resonant with
current thinking in the emerging fields of geobiology and Earth
System Science. It provides an alternative, process-based
classification of ecology and proposes a truly planetary view of
ecological science. To achieve this, it asks (and endeavours to
answer) the question, "what are the fundamental ecological
processes which would be found on any planet with Earth-like,
carbon based, life?"
Over millions of years, terrestrial plants have competed for limited resources, defended themselves against herbivores, and resisted a myriad of environmental stresses. These struggles have helped generate more than a quarter million terrestrial plant species, each possessing a unique strategy for success. Yet, as "Resource Strategies of Wild Plants" demonstrates, the constraints on plant growth are universal enough that a few survival strategies hold true for all seed-producing plants. This book describes the five major strategies of growth for terrestrial plants, details how plants succeed when resources are scarce, delves into the history of research into plant strategies, and resets the foundational understanding of ecological processes. Drawing from recent findings in plant-herbivore interactions, ecosystem ecology, and evolutionary ecology, Joseph Craine explains how plants attain available nutrients, withstand the immense stresses of drying soils, and flourish in the race for light. He shows that the competition for resources has shaped plant evolution in newly discovered ways, while the scarcity of such resources has affected how plants interact with herbivores, wind, fire, and frost. An understanding of the major resource strategies of wild plants remains central to learning about the ecology of plant communities, global changes in the biosphere, methods for species conservation, and the evolution of life on earth.
Most textbooks on measuring terrestrial vegetation have focused on the characteristics of biomass, cover, and the density or frequency of dominant life forms (trees, shrubs, grasses, and forbs), or on classifying, differentiating, or evaluating and monitoring dominant plant communities based on a few common species. Sampling designs for measuring species richness and diversity, patterns of plant diversity, species-environment relationships, and species distributions have received less attention. There are compelling, urgent reasons for plant ecologists to do a far better job measuring plant diversity in this new century. Rapidly invading plant species from other countries are affecting rangeland condition and wildlife habitat, placing more plant species on threatened and endangered species lists, and increasing wildfire fuel loads. Attention has shifted from the classification of plant communities to accurately mapping rare plant assemblages and species of management concern to afford them better protection. More ecologists, wildlife biologists, and local and regional planners recognize the value in understanding patterns, dynamics, and interactions of rare and common plant species and habitats to better manage grazing, fire, invasive plant species, forest practices, and restoration activities. Thus, revised and new sampling approaches, designs, and field techniques for measuring plant diversity are needed to assess critical emerging issues facing land managers. This book offers alternatives to the approaches, designs, and techniques of the past that were chiefly designed for dominant species and other purposes. The author focuses on field techniques that move beyond classifying, mapping, and measuring plant diversity for relatively homogeneous communities. This book complements methods for measuring the biomass and cover of dominant plant species. Most species are sparse, rare, and patchily distributed. It empowers the reader to take an experimental approach in the science of plant diversity to better understand the distributions of common and rare species, native and non-native species, and long-lived and short-lived species.
This book has been written in an attempt to advance people's knowledge on the Lima bean (Phaseolus lunatus) crop in tropical and sub-tropical regions. The Lima bean is an important species of plant for humans in tropical regions and its seeds are considered an important source of protein for people from South America, Africa, and Mexico. There is little information about the Lima bean crop regarding its origin, diversity, evolution, growth and production. This book encompasses nine chapters on the topic to provide a broad knowledge of this fascinating crop. The first three chapters cover the origin, diversity and evolution of the crop, including important information from Mexico and Brazil. Chapter Four covers the phenology and development of the Lima bean aiming to understand all periods of growth. Chapter Five shows important information for plant production regarding soil, chemical and organic fertilisation. Chapters Six and Seven explain all aspects related to biological nitrogen fixation with information about soil bacterial diversity and the potential to fix the problem in tropical soil. Chapter Eight reports important diseases related to the Lima bean and their management. Chapter Nine shows the social and economic importance of the Lima bean mainly for developing countries.
Encyclopedia of Ecology, Second Edition, Four Volume Set continues the acclaimed work of the previous edition published in 2008. It covers all scales of biological organization, from organisms, to populations, to communities and ecosystems. Laboratory, field, simulation modelling, and theoretical approaches are presented to show how living systems sustain structure and function in space and time. New areas of focus include micro- and macro scales, molecular and genetic ecology, and global ecology (e.g., climate change, earth transformations, ecosystem services, and the food-water-energy nexus) are included. In addition, new, international experts in ecology contribute on a variety of topics.
With more than 500 species distributed all around the Northern Hemisphere, the genus Quercus L. is a dominant element of a wide variety of habitats including temperate, tropical, subtropical and mediterranean forests and woodlands. As the fossil record reflects, oaks were usual from the Oligocene onwards, showing the high ability of the genus to colonize new and different habitats. Such diversity and ecological amplitude makes genus Quercus an excellent framework for comparative ecophysiological studies, allowing the analysis of many mechanisms that are found in different oaks at different level (leaf or stem). The combination of several morphological and physiological attributes defines the existence of different functional types within the genus, which are characteristic of specific phytoclimates. From a landscape perspective, oak forests and woodlands are threatened by many factors that can compromise their future: a limited regeneration, massive decline processes, mostly triggered by adverse climatic events or the competence with other broad-leaved trees and conifer species. The knowledge of all these facts can allow for a better management of the oak forests in the future.
Air pollution affects every living organism, including all kinds of vegetation on which we depend for survival. The second edition of this standard reference textbook provides a comprehensive and up-to-date overview of the direct and indirect impacts of air pollution on plant life. Written by an international team of experts, the book also covers the main historical aspects and sources of pollutants, atmospheric transport and transformations of pollutants, and issues of global change and the use of science in air pollution policy formulation. Air Pollution and Plant Life Second Edition is a unique text in several ways:
This book describes the Kluane Boreal Forest Ecosystem Project which operated from 1986 to 1996 in the southwestern Yukon. It begins by describing the area and its physical setting, and then the background of the project and the wisdom that had accumulated to 1986, on how this system might operate. The details of the experiments set up are presented, partly to help the reader appreciate the difficulty of working at -40 degrees and partly to aid the reader should they contemplate doing similar experiements in the future. Then they examine the three trophic levels of plants, the herbivores, and the predators in detail to provide some surprises about how the individual species operate within the overall system. Finally, they synthesize their findings in a model of the boreal forest vertebrate community, and provide an overview of what they have discovered and what remains to be done. Over the ten years of this project a large number of students and researchers have joined together to produce a picture which makes major advances in our understanding of the boreal forest ecosystem.
Each plant species has its own unique passage that is affected by its gene pool, dispersal ability, interactions with competitors and pests, and the habitats and climactic conditions to which it is exposed. This book will explore plant species as dynamic entities within this passage, following the four stages of plant species life that normally occur. Those four stages can be identified as birth, expansion, differentiation and loss of cohesion, and decline/extinction. Each chapter focuses on part of the speciation process and examines it closely in the light of exploring the species passage from birth to death. |
