Urbanization is a global phenomenon that is increasingly challenging human society. It is therefore crucially important to ensure that the relentless expansion of cities and towns proceeds sustainably. Urban ecology, the interdisciplinary study of ecological patterns and processes in towns and cities, is a rapidly developing field that can provide a scientific basis for the informed decision-making and planning needed to create both viable and sustainable cities. Urban Ecology brings together an international team of leading scientists to discuss our current understanding of all aspects of urban environments, from the biology of the organisms that inhabit them to the diversity of ecosystem services and human social issues encountered within urban landscapes. The book is divided into five sections with the first describing the physical urban environment. Subsequent sections examine ecological patterns and processes within the urban setting, followed by the integration of ecology with social issues. The book concludes with a discussion of the applications of urban ecology to land-use planning. The emphasis throughout is on what we actually know (as well as what we should know) about the complexities of social-ecological systems in urban areas, in order to develop urban ecology as a rigorous scientific discipline.

Biological Diversity provides an up to date, authoritative review of the methods of measuring and assessing biological diversity, together with their application. The book's emphasis is on quantifying the variety, abundance, and occurrence of taxa, and on providing objective and clear guidance for both scientists and managers. This is a fast-moving field and one that is the focus of intense research interest. However the rapid development of new methods, the inconsistent and sometimes confusing application of old ones, and the lack of consensus in the literature about the best approach, means that there is a real need for a current synthesis. Biological Diversity covers fundamental measurement issues such as sampling, re-examines familiar diversity metrics (including species richness, diversity statistics, and estimates of spatial and temporal turnover), discusses species abundance distributions and how best to fit them, explores species occurrence and the spatial structure of biodiversity, and investigates alternative approaches used to assess trait, phylogenetic, and genetic diversity. The final section of the book turns to a selection of contemporary challenges such as measuring microbial diversity, evaluating the impact of disturbance, assessing biodiversity in managed landscapes, measuring diversity in the imperfect fossil record, and using species density estimates in management and conservation.

One of the main objectives of nature conservation in Europe is to protect valuable cultural landscapes characterized by a mixture of open habitats and hedges, trees and patchy woodland (semi-open landscapes).The development of these landscapes during the past decades has been characterized by an ongoing intensification of land use on the one hand, and an increasing number of former meadows and pastures becoming fallow as a result of changing economic conditions on the other hand. Since species adapted to open and semi-open landscapes contribute to biodiversity in Europe in a major way, this development is of great concern to nature conservation. In several countries largescale, nature-adapted pastoral systems have been recognized as one solution to this problem. These systems could offer an alternative to industrial livestock raising and keep a high biodiversity on the landscape level. Against the background of livestock diseases such as BSE and Foot and Mouth Disease and the efforts to reform the Common Agricultural Policy in the EU by changing the criteria for agricultural subsidies, these concepts gain particular significance.They could also represent an alternative to the established, costly habitat management tools.

This concise, readable introduction to limnology (the science of investigating the structure and function of inland waters), places the subject in the context of modern ecology. Unlike most ecological textbooks, which use examples taken almost exclusively from terrestrial systems, this book integrates the fields of limnology and ecology by presenting empirical data drawn entirely from freshwater ecosystems in order to advance ecological theories (limnoecology).
This second edition builds upon the strengths of the first with the structure of the book following the same hierarchical concept of ecology, from habitat properties, individuals, populations, coupled populations and communities to ecosystems. However, it has been thoroughly revised throughout to incorporate findings from new technologies and methods (notably the rapid development of molecular genetic methods and stable isotope techniques) that have allowed a rapid and ongoing development of the field. There is a new emphasis on food webs, species diversity and ecosystem functioning, climate change, and conservation management. Key ecological questions are examined in the light of the latest experimental evidence. Throughout the text evolutionary theory is applied to an understanding of freshwater ecosystems, thereby filling a niche between traditional limnology and evolutionary ecology.
This accessible text is suitable for both undergraduate and graduate students taking courses in limnology, freshwater ecology, and aquatic biology as well as the many professional limnologists, ecologists and conservation biologists requiring a concise but authoritative overview of the topic.

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.

Mitton explains the questions that geneticists hoped to answer by studying protein variation. He reviews the extensive literature on protein variation, describes the successes and failures of the research program, and evaluates the results of a rich and controversial body of research. It is a history of the research of genetic variation, as well as a useful analysis for all geneticists interested in the genetic structure and evolution of populations.

Within the current context of global interest in biological diversity, this is a timely review of the most recent research into the evolutionary origins of biological diversity and the processes of speciation, from a stellar cast of contributors. The chapters in this book explore the question of how variation arises within species; some emphasize the ecological and behavioural basis of differentiation; others argue for the role of natural selection in generating speciation. Several chapters focus on the important emerging links between sexual selection, sexual conflict, and population differentiation. The final chapters explore the fossil record for data on the origination of species diversity - and extinctions - in the past. This book is a must-have for all researchers and graduate students in the biological sciences who want to be abreast of the latest thinking on the evolution of biological diversity.

The papers included in this readings text were selected and are introduced by the authors of Ecology as examples of excellent and insightful research that greatly contributes to our grasp and exploration of ecological questions. These studies span the range of ecological perspectives and are significant reading for every student in the life sciences.

Ecological Dynamics is unique in that it can serve both as an introductory text in numerous ecology courses and as a resource for more advanced work. It provides a flexible introduction to ecological dynamics that is accessible to students with limited previous mathematical and computational experience, yet also offers glimpses into the state of the art in the field.

The book is divided into three parts: Part I, Methodologies and Techniques, defines the authors' modeling philosophy, focusing on models rather than ecology, and introduces essential concepts for describing and analyzing dynamical systems. Part II, Individuals to Ecosystems, the core of the book, describes the formulation and analysis of models of individual organisms, populations, and ecosystems. Part III, Focus on Structure, introduces more advanced readers to models of 'structured' and spatially extended populations. Approximately 25% of the book is devoted to case studies drawn from the authors' research. Readers are guided through the many judgment calls involved in model formulation, shown the key steps in model analysis, and offered the authors' interpretation of the results. All chapters end with exercises and projects. While the book is designed to be independent of any particular computing environment, a well-tested software package (SOLVER),including programs for solution of differential and difference equations, is available via the World Wide Web at http://www.stams.strath.ac.uk/external/solver.

Ideal for courses in modeling ecological and environmental change, Ecological Dynamics can also be used in other courses such as theoretical ecology, population ecology, mathematical biology and ecology, and quantitative ecology.

Unlike animals that can run from danger or migrate to a more hospitable environment, plants must rely on adaptations that permit them to survive where they are. The fascinating mechanisms that plants employ to survive in challenging environments are clearly explained and illustrated in this primer, suitable for young and mature readers alike.

When initially published more than twenty years ago, Thinking Like a Mountain was the first of a handful of efforts to capture the work and thought of America's most significant environmental thinker, Aldo Leopold. This new edition of Susan Flader's masterful account of Leopold's philosophical journey, including a new preface reviewing recent Leopold scholarship, makes this classic case study available again and brings much-deserved attention to the continuing influence and importance of Leopold today. Thinking Like a Mountain unfolds with Flader's close analysis of Leopold's essay of the same title, which explores issues of predation by studying the interrelationships between deer, wolves, and forests. Flader shows how his approach to wildlife management and species preservation evolved from his experiences restoring the deer population in the Southwestern United States, his study of the German system of forest and wildlife management, and his efforts to combat the overpopulation of deer in Wisconsin. His own intellectual development parallels the formation of the conservation movement, reflecting his struggle to understand the relationship between the land and its human and animal inhabitants. Drawing from the entire corpus of Leopold's works, including published and unpublished writing, correspondence, field notes, and journals, Flader places Leopold in his historical context. In addition, a biographical sketch draws on personal interviews with family, friends, and colleagues to illuminate his many roles as scientist, philosopher, citizen, policy maker, and teacher. Flader's insight and profound appreciation of the issues make Thinking Like a Mountain a standard source for readers interested in Leopold scholarship and the development of ecology and conservation in the twentieth century.

Using cases of plant migration documented by both historical and fossil evidence, Jonathan D. Sauer provides a landmark assessment of what is presently known, and not merely assumed, about the process.

Over the past two decades, numerous field and experimental studies on the ecology and evolution of animal and plant interactions have been reported by botanists, zoologists, and ecologists. This textbook offers a comprehensive summary of this extensive and widely scattered literature, and in so doing presents the subject as a coherent, accessible discipline. The authors describe familiar areas, such as herbivory and pollination, and discuss new information on subjects such as seed dispersal, the genetics of coevolution, structural and chemical plant defenses, and the implications of human use of animal and plant communities. As they explore these issues, the authors raise provocative questions of fundamental importance: How can an earth teeming with plant-eating animals be so green? Do plants really need animals that pollinate their flowers and disperse their seeds? What happens to tropical plant communities when fruit-eating toucans and monkeys are killed by encroaching humans? By drawing together information on many diverse aspects of the subject--and presenting a challenging and insightful look into the complexities of plant and animal inter-relationships--this unique book represents a vital contribution to the ecological literature.

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.

This book presents the state of the skill of understanding brassinosteroids (BRs) signaling plus crosstalk with phytohormone and their association in plant adaptation to abiotic stresses comprising physiological, biochemical, and molecular developments. Due to progressively adverse environmental conditions and scarce natural resources, high-efficient crops have become more important than ever. For the successful improvement of stress-tolerant plants, it is vital to understand the precise signaling appliances that plants practice to abide stresses as well as how much these mechanisms are convinced by phytohormone. However, it is also debatable on which step plants can attain brassinosteroids (BRs) signaling from an evolutionary viewpoint. BRs are involved in modulating a large array of important functions throughout a plant's life cycles. BRs are considered as one of the most important plant steroidal hormones that show a varied role in observing a wide range of developmental practices in plants. Our grip on brassinosteroids signaling has quickly extended over the past two decades, owing in part to the isolation of the constituents intricate in the signal transduction trail. The book proposes a useful guide for plant researchers and graduate students in connected areas.

Plant Ecology & Conservation is an introduction to the world of plant ecology. It includes the main areas of current research including ideas about plant populations, nutrition and plant community ecology and has a particular emphasis on the interactions of plants with animals, fungi and microorganisms whose important is being increasingly demonstrated. With the world's environmental problems having such a high profile, the book focusses on the human impact on the world's plant species. Conservation of the terrestrial world starts with plants as they form the basis of all ecosystems on land. We can only understand how best to conserve the world's biodiversity with an understanding of the central role of plant ecology. This theme runs throughout with numerous examples of the disruption of ecosystems by human activity emphasising the connection between plant ecology and conservation. Key Features: Boxes present case studies, important statistics and interesting asides Full-colour photos depict key species and habitats and superb line drawings illustrate many concepts Important data are presented in Tables and Figures throughout Each chapter has Key Concepts and review questions to test a reader's grasp of the content Key References and Further Reading are given for each chapter to point the reader towards the most important and influential literature Jargon is kept to a minimum and a full Glossary of all technical terms is presented The book is aimed primarily at undergraduate and graduate students in any aspect of ecology or plant science. It should also appeal to anyone interested in how plants function and are concerned about what is needed for the conservation of the world's ecosystems.

This book emphasizes the necessity of green spaces and landscape planning to achieve a liveable city. It will more specifically enquire on how to reach a better liveability from the current conditions of Lima. This book takes on the one hand classic concepts from urban agronomy as are soil, water and plants, and on the other hand emphasizes the resources, the plant adaptations and the urban ecosystems, according to the context of Lima. Comparisons are also made to landscape concepts from other cities of the word, contemporary methods of urban landscape research are explained in perspectives of agronomy and ecology. The ecological restoration of some natural spaces of Lima are proposed and related to the food security which impacts on the sustainability of the city. Finally, it describes representative Parks of Lima and previous research projects that have allowed to improve the urban landscape. Considering the city's cultural diversity, comparisons to the mountain and rainforest areas are also made.

Marine macrophytes (macroalgae, seagrasses, and mangroves) comprise thousands of species distributed in shallow water areas along the world's coastlines. They play a key role in marine ecosystems regarding biodiversity and energy flow. A large proportion of macrophyte species can be characterised as ecosystem engineers-organisms that directly or indirectly affect the availability of resources to other species by modifying, maintaining, and creating habitats. This book is divided into three main themes: * Marine macroalgae and seagrasses as sources of biodiversity gives an overview of the diversity of the main organisms associated with macrophytes, and their functional role and interactions within their hosts. * Primary and secondary production of Macrophytes synthesizes research on food web structures derived from/or associated with, macrophytes and the transfer of macrophytic primary and secondary production from one ecosystem to another. * Threats to macrophytic ecosystem engineers addresses human-induced effects including eutrophication, physical destruction, invasive species, and global warming. The book is among the first one to concentrate on the value of macrophytes for the well-being of marine habitats. The book is aimed at academics but may be useful for students, policy makers, and laymen alike.

The field of plant population ecology has advanced considerably in the last decade since the first edition was published. In particular there have been substantial and ongoing advances in statistics and modelling applications in population ecology, as well as an explosion of new techniques reflecting the availability of new technologies (e.g. affordable and accurate Global Positioning Systems) and advances in molecular biology. This new edition has been updated and revised with more recent examples replacing older ones where appropriate. The book's trademark question-driven approach has been maintained and some important topics such as the metapopulation concept which are missing entirely from the current edition are now included throughout the text.

Ectomycorrhizal symbiosis plays a major role in biodiversity and stability of ecosystems in tropical forests. It is a research imperative in tropical and neotropical forest ecosystems because they contain ecologically and economically important tree species. This book provides an overview of the knowledge of ECM symbioses in tropical and neotropical ecosystem forests. The contents address diversity and function of ectomycorrhiza associated with forest plants, impacts of ectomycorrhiza on plant diversity and composition, regeneration and dynamics of ecosystems, biomass production in forestry, and adaptation of ectomycorrhiza.

Pillars of Evolution provides a fresh and provocative perspective on adaptive evolution. Readers new to the study of evolution will find a refreshing new insight that establishes evolutionary biology as a rigorous and predictive science, whilst practicing biologists will discover a provocative book that challenges traditional approaches.
The book begins by leading readers through the mechanics of heredity, reproduction, movement, survival, and development. With that framework in place, it then explores the numerous ways that traits emerge from the interactions between genetics, development, and the environment. The key message is that adaptive changes in traits (and their underlying allelic frequencies) evolve through the traits' functions and their connection with fitness. The complex mappings from genes-to-traits-to-fitness are characterized in the structure of evolution. A single "structure matrix" describes why individuals vary in the values of adaptive traits, their ability to perform the function of those traits, and in the fitness they accrue. Fitness depends on how organisms interact with and perceive their environment in time and space. These relationships are made explicit in spatial, temporal, and organizational scale that also sets the stage for the crucially important role that ecology always plays in evolution. The ecological hallmarks of density- and frequency-dependent interactions allow the authors to explore new and exciting insights into evolution's dynamics. The theories and principles are then brought together in a final synthesis on adaptation.
The book's unique approach unites genetic, development, and environmental influences into a single comprehensive treatment of the eco-evolutionary process.

The spatial aspects of epidemics have been a largely ignored feature of plant ecology, yet an understanding of the spatial dynamics for pathogens is essential to quantifying the impact of diseases on wild plants. Moreover, it may provide valuable information for the control of human diseases. This seminal work fulfills such a role by describing the basics of botanical epidemiology within the context of plant ecology. A variety of models are covered to estimate key parameters at both the individual plant and population levels, with emphasis on the value of spatial-temporal models in the evolutionary dynamics of pathogens. Practical methods are presented to validate these models, thus making this book accessible to theorists and empiricists alike.

This reference explores the molecular, biochemical, functional, structural, and developmental mechanisms of pH in plant growth-examining the role of pH in plant symplasm, plant apoplasm, the rhizosphere, the ecosystem, and in plant interaction with biotic and abiotic environments. Analyzing the complexities of plant life from biological processes to cell organelles and molecules, the Handbook of Plant Growth is an excellent and authoritative reference for plant, crop, soil, and environmental scientists; plant and crop physiologists; botanists; agronomists; agriculturists; horticulturists; biochemists; foresters; and upper-level undergraduate, graduate, and continuing-education students in these disciplines.

While scientific and socio-political communities around the world are aware of the natural and economic importance of biodiversity, we are faced with an ever-increasing number of plant species under threat of extinction. Conservation is thus a vital part of the plant scientist's work, in the field, in botanic gardens and in universities. This colour atlas has been conceived to integrate the dual botanical themes of plant propagation and conservation. Various texts deal with propagation, in vivo and in vitro, and with aspects of conservation, but none marries the two themes, let alone a book which uses the concise, focused colour atlas approach. Each of the chapters has been written by an acknowledged international authority on the subject, under the editorship of Dr Bryan Bowes whose Colour Guide to Plant Structure (2nd edition 2008) is already highly successful. Topics range from the history and likely future of conservation and the effects of human activity on plant diversity, to the practical techniques of collection, preservation, germination, propagation and management of plant populations in the laboratory and in the field. The text is referenced and is illustrated throughout by colour photos and photomicrographs of the highest quality. It appeals worldwide to students of conservation, plant science and biology, and to professionals and academics, plant propagators, ecologists, and conservationists working in botanic gardens, universities and colleges, in field research and in nurseries specialising in indigenous plants.
