Network thinking and network analysis are rapidly expanding features of ecological research. Network analysis of ecological systems include representations and modelling of the interactions in an ecosystem, in which species or factors are joined by pairwise connections. This book provides an overview of ecological network analysis including generating processes, the relationship between structure and dynamic function, and statistics and models for these networks. Starting with a general introduction to the composition of networks and their characteristics, it includes details on such topics as measures of network complexity, applications of spectral graph theory, how best to include indirect species interactions, and multilayer, multiplex and multilevel networks. Graduate students and researchers who want to develop and understand ecological networks in their research will find this volume inspiring and helpful. Detailed guidance to those already working in network ecology but looking for advice is also included.

Climb a mountain and experience the landscape. Try to grasp its holistic nature. Do not climb alone, but with others and share your experience. Be sure the ways of seeing the landscape will be very different. We experience the landscape with all senses as a complex, dynamic and hierarchically structured whole. The landscape is tangible out there and simultaneously a mental reality. Several perspectives are obvious because of language, culture and background. Many disciplines developed to study the landscape focussing on specific interest groups and applications. Gradually the holistic way of seeing became lost. This book explores the different perspectives on the landscape in relation to its holistic nature. We start from its multiple linguistic meanings and a comprehensive overview of the development of landscape research from its geographical origins to the wide variety of today's specialised disciplines and interest groups. Understanding the different perspectives on the landscapes and bringing them together is essential in transdisciplinary approaches where the landscape is the integrating concept.

The development of computer simulation models is an important growth area in both pure and applied ecology. The opportunity that mathematical models provide to integrate the components of an ecosystem, results in the ability to make quantitative predictions about the future behaviour of that system, or of elements within it. This means that they are powerful tools with wide applications and enormous potential for increasing our understanding of natural systems and our ability to use them in a sustainable way. This book is, almost uniquely, a complete account of one such model, the Hurley Pasture Model, a dynamic, deterministic, mechanistic simulation model for grassland, which has been developed by the author over some twenty years, in collaboration with scientists at several centres. Firstly, the rationale and theoretical elements of this type of model are described. An overview of the Hurley grassland simulator and the derivation and construction of its plant, animal, soil and litter, water, and environment and management components is then given. Next, the model is evaluated by a series of long and short-term dynamic simulations and steady state responses, which demonstrate how predictions can be made about the effects of, for example, climate change or particular regimes of fertilizer application, grazing or cutting. This book will be of great value to grassland agronomists and modellers, crop physiologists and plant ecologists, and to students of ecology as a case study of a plant ecosystem model. It will also be of interest to other ecologists and environmentalists and those in the field of computer modelling and its applications.

Plant species which can accumulate high concentrations of heavy metals have been known for over one hundred years. However, until the last twenty years their potential went largely unnoticed by scientists. The term hyperaccumulation was first introduced by the author (and colleagues) in 1977. This renewed interest, together with heightened environmental awareness and the discovery of the phenomenon in many more species has since stimulated research into a number of novel scientific and commercial uses. This book brings together for the first time in one volume all the relevant ecological information on hyperaccumulators and describes the new disciplines, methods and uses for them which continue to be explored. These include the removal of heavy metal pollutants from soils and waters (phytoremediation), the identification of ancient human settlements (phytoarchaeology), mineral exploration, the revegetation of degraded land and the exciting possibility of the commercial extraction of heavy metals from crop plants (phytomining). This book is essential reading for plant ecologists and physiologists who have an interest in hyperaccumulators, environmental consultants specialising in land restoration, and exploration geochemists. It will also be of great interest to professionals, lecturers and advanced students in environmental science, geology and soil science.

A great many terrestrial plants live in close association with fungi. The features of this association known as mycorrhiza, are those of a mutualistic symbiosis. Almost all plants form mycorrhizae whereby the fungus provides soil resources to the plant in exchange for energy manufactured by the plant. The symbiosis means greater productivity under stress for the plant and a steady energy supply for the fungus. This book addresses the diverse and complex ways in which mycorrhizae affect the mechanisms for plant survival as individuals and populations, for community structure, and for ecosystem functioning. It integrates information on organisms interacting with mycorrhizae from bacteria to mammals. The author takes a unique evolutionary/ecological approach to describe how and under what conditions mycorrhizae influence basic ecological processes. The applications of mycorrhizal symbioses range from managing natural and agricultural lands to biotechnological processes that enhance agricultural productivity and sustainability.

Correlation between plant distribution and climate is examined over different time and space scales to determine the mechanisms of control in physiological and biochemical terms.

GREEN HUMOUR FOR A GREYING PLANET is a curation of gag cartoons and comic strips based exclusively on wildlife and nature, perhaps the first of its kind. At a time when global warming, wildlife crimes and man-animal conflicts are at their worst, 'Green Humour' is sure to provide its readers some much needed comic relief. A comprehensive and satirical take on various aspects of the natural world and the threats to its conservation, this book will appeal to both the scientifically inclined readers as well as the general readers.

Having been the fourth largest lake on the globe roughly 50 years ago, today the Aral Sea no longer exists. Human activities caused its desiccation and the formation of a huge new desert, the Aralkum, which can be regarded as one of the greatest ecological catastrophes and - at the same time - the largest primary succession experiment of mankind.

This volume brings together the results of international and interdisciplinary long-term studies on the new desert ecosystem and is divided into four main sections. The first section provides an overview of the physical characteristics of the area and covers geological, pedological, geomorphological and climatological aspects and their dynamics, especially dust-storm dynamics. The second focuses on the biotic aspects and highlights the spatial and temporal patterns of the flora and fauna. In the third section studies and projects aiming to combat desertification by phytomelioration and to develop strategies for the conservation of biodiversity are presented. The book is rounded off with a section providing a synthesis and conclusions.

Until recently, the production of fruits by plants, their consumption by animals (frugivory) and the relevance of these to seed dispersal have attracted less attention than topics such as pollination biology. However, since the 1970s they have started to gain more prominence and now give rise to more research funding, seminal papers and international symposiums. This book contains chapters adapted from the Third International Symposium-Workshop on Frugivores and Seed Dispersal held in August 2000, in Rio Quente, Brazil.

This book aims to assist in choosing ecotechnological solutions for slopes that are prone to a variety of mass movements e.g. shallow failure or erosion. The book reviews the types of problematic slopes that may occur and describes briefly the nature of mass movements and the causes of these movements. There is focus on the use of vegetation to stabilize soil on slopes prone to mass movements. The book also introduces new ecotechnological methods, and case studies are discussed.

Increasing evidence suggests that the composition and spatial configuration - the pattern - of forest landscapes affect many ecological processes, including the movement and persistence of particular species, the susceptibility and spread of disturbances such as fires or pest outbreaks, and the redistribution of matter and nutrients. Understanding these issues is key to the successful management of complex, multifunctional forest landscapes, and landscape ecology, based on a foundation of island bio-geography and meta-population dynamic theories, provides the rationale to deal with this pattern-to-process interaction at different spatial and temporal scales.

This carefully edited volume represents a stimulating addition to the international literature on landscape ecology and resource management. It provides key insights into some of the applicable landscape ecological theories that underlie forest management, with a specific focus on how forest management can benefit from landscape ecology, and how landscape ecology can be advanced by tackling challenging problems in forest (landscape) management. It also presents a series of case studies from Europe, Asia, North America, Africa and Australia exploring the issues of disturbance, diversity, management, and scale, and with a specific focus on how human intervention affects forest landscapes and, in turn, how landscapes influence humans and their culture.

An important reference for advanced students and researchers in landscape ecology, conservation biology, forest ecology, natural resource management and ecology across multiple scales, the book will also appeal to researchers and practitioners in reserve design, ecological restoration, forest management, landscape planning and landscape architecture.

Metacommunity ecology links smaller-scale processes that have been the provenance of population and community ecology--such as birth-death processes, species interactions, selection, and stochasticity--with larger-scale issues such as dispersal and habitat heterogeneity. Until now, the field has focused on evaluating the relative importance of distinct processes, with niche-based environmental sorting on one side and neutral-based ecological drift and dispersal limitation on the other. This book moves beyond these artificial categorizations, showing how environmental sorting, dispersal, ecological drift, and other processes influence metacommunity structure simultaneously. Mathew Leibold and Jonathan Chase argue that the relative importance of these processes depends on the characteristics of the organisms, the strengths and types of their interactions, the degree of habitat heterogeneity, the rates of dispersal, and the scale at which the system is observed. Using this synthetic perspective, they explore metacommunity patterns in time and space, including patterns of coexistence, distribution, and diversity. Leibold and Chase demonstrate how these processes and patterns are altered by micro- and macroevolution, traits and phylogenetic relationships, and food web interactions. They then use this scale-explicit perspective to illustrate how metacommunity processes are essential for understanding macroecological and biogeographical patterns as well as ecosystem-level processes. Moving seamlessly across scales and subdisciplines, Metacommunity Ecology is an invaluable reference, one that offers a more integrated approach to ecological patterns and processes.

In addition to exploring the processes by which seaweeds, as individuals and communities, interact with their biotic and abiotic environment, the book presents exciting new research on how seaweeds respond to local and global environmental change. It remains an invaluable resource for students and provides an entry into the scientific literature of a wide range of topics.

This advanced textbook explores the intriguing flora and plant ecology of the Middle East, framed by a changing desert landscape, global climate change, and the arc of human history. This vast region has been largely under-recognized, under-studied, and certainly under-published, due in part to the challenges posed to research by political disputes and human conflict, and a treatise on the subject is now timely. The book integrates Middle Eastern plant geography and its major drivers (geo-tectonics, seed and fruit dispersal, plant functional types, etc.) with the principles of plant ecology. The authors include the many specialized adaptations to desert and dryland ecosystems including succulence, water-conserving photosynthesis, and a remarkable range of other life history strategies. They explore the formation of 'climate relicts', and describe the long history of domestication in the region together with the many reciprocal effects of agriculture on plant ecology. The book concludes by discussing conservation in the region, highlighting five regional biodiversity hotspots where the challenges of desertification, habitat loss, and other threats to plant biodiversity are particularly acute. Plant Ecology in the Middle East is a timely synthesis of the field, setting a new baseline for future research. It will be important reading for both undergraduate and graduate students taking courses in plant ecology, evolution, systematics, biodiversity, and conservation, and will also be of interest and use to a professional audience of botanists, conservation biologists, and practitioners working in dryland ecosystems.

Despite its small size, Belize is one of the most ecologically and culturally diverse nations in Central America. Over 3,400 species of plants can be found here, within a diversity of ecological habitats. Because of this, Belize is paradise for ecotourists, hosting over 900,000 visitors annually, who enjoy the natural habitat and friendly people of this nation. Many of the plants of Belize have a long history of being "useful," with properties that have served traditional herbal healers of the region as well as those who use plants as food, forage, fiber, ornament, in construction and ritual, along with many other purposes. With Messages from the Gods: A Guide to the Useful Plants of Belize, Drs. Michael Balick and Rosita Arvigo give us the definitive resource on the many species of plants in Belize and their folklore, as well as the natural history of the region and a detailed discussion of "bush" uses of plants, including for traditional healing and life in the forest, past and present. Both Balick and Arvigo bring important perspectives to the project, Balick as ethnobotanical scientist from The New York Botanical Garden, and Arvigo as a former apprentice to a Belizean healer and an experienced physician. The book has been decades in the making, a culmination of a biodiversity research project that The New York Botanical Garden and international and local collaborators have had in motion since 1987. Drs. Balick, Arvigo and their colleagues have collected and identified thousands of plants from the region, and have worked extensively with hundreds of Belizean people, many of them herbal healers and bushmasters, to record uses for many of the species. This collaboration with local plant experts has produced a fascinating discussion of the intersection of herbal medicine and spiritual belief in the area, and these interviews are used to compliment and contextualize the numerous species accounts presented. The book is both a cultural study and a specialized field guide; information is provided on many different native and introduced plants in Belize and their traditional and contemporary uses including as food, medicine, fiber, in spiritual practices and many other purposes. Richly illustrated with over 600 images and photographs, Messages from the Gods: A Guide to The Useful Plants of Belize will serve as the primary reference and guide to the ethnobotany of Belize for many years to come.

Mangroves and seagrasses form extensive and highly productive ecosystems that are both biologically diverse and economically valuable. This book, now in its third edition and fully updated throughout, continues to provide a current and comprehensive introduction to all aspects of the biology and ecology of mangroves and seagrasses. Using a global range of examples and case studies, it describes the unique adaptations of these plants to their exacting environments; the rich and diverse communities of organisms that depend on mangrove forests and seagrass meadows (including tree-climbing shrimps, synchronously flashing fireflies, and 'gardening' seacows); the links between mangrove, seagrass, and other habitats; and the evolution, biodiversity, and biogeography of mangroves and seagrasses. The economic value of mangroves and seagrasses is also discussed, including approaches to rational management of these vital resources and techniques for the restoration of degraded habitats. A final chapter, new to this edition, examines the potential effects of global climate change including sea level rise. As with other titles in the Biology of Habitats Series, particular emphasis is placed on the organisms that dominate these fascinating aquatic ecosystems although pollution, conservation, and experimental aspects are also considered. This accessible textbook assumes no previous knowledge of mangrove or seagrass ecology and is intended for senior undergraduate and graduate students, as well as professional ecologists, conservation practitioners, and resource managers.

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.
