The scientific study of networks - computer, social, and biological - has received an enormous amount of interest in recent years. However, the network approach has been applied to the field of animal behaviour relatively late compared to many other biological disciplines. Understanding social network structure is of great importance for biologists since the structural characteristics of any network will affect its constituent members and influence a range of diverse behaviours. These include finding and choosing a sexual partner, developing and maintaining cooperative relationships, and engaging in foraging and anti-predator behavior. This novel text provides an overview of the insights that network analysis has provided into major biological processes, and how it has enhanced our understanding of the social organisation of several important taxonomic groups. It brings together researchers from a wide range of disciplines with the aim of providing both an overview of the power of the network approach for understanding patterns and process in animal populations, as well as outlining how current methodological constraints and challenges can be overcome. Animal Social Networks is principally aimed at graduate level students and researchers in the fields of ecology, zoology, animal behaviour, and evolutionary biology but will also be of interest to social scientists.

Savannah habitats comprise an ecologically important, but ultimately fragile, ecosystem. They constitute one of the largest biomes on Earth, covering almost 20% of the land surface, and can be simply described as tropical and subtropical grasslands with scattered bushes and trees. Most savannahs occur in Africa, although smaller areas can be found in South America, India, and Australia. They form a rich mosaic of diverse ecosystems, and this book offers a concise but comprehensive introduction to their ecology, biodiversity, and conservation. The Biology of African Savannahs describes the major plants (grasses, and trees such as Acacia) and animals (mainly large mammals) that live in this habitat, and examines the biological and ecological factors that influence their population size, interactions (such as predation), and community composition. Conservation issues such as climate change, hunting, and conflict between wildlife and domestic animals are also discussed. This new edition has been updated throughout with the latest research in the field, and contains new technique boxes which introduce readers to some of the analytical methods used to study African savannahs. This accessible text is suitable for both senior undergraduate and graduate students taking courses in savannah and tropical ecology as part of a wider ecology and/or conservation biology degree programme. It will also be of relevance and use to the many professional ecologists and conservation practitioners requiring a concise but authoritative overview of the topic.

Insects display a staggering diversity of mating and social behaviours. Studying these systems provides insights into a wide range of evolutionary and behavioural questions, such as the evolution of sex, sexual selection, sexual conflict, and parental care. This edited volume provides an authoritative update of the landmark book in the field, The Evolution of Insect Mating Systems (Thornhill and Alcock, 1983), which had such a huge impact in shaping adaptationist approaches to the study of animal behaviour and influencing the study of the evolution of reproductive behaviour far beyond the taxonomic remit of insects. This accessible new volume brings the empirical and conceptual scope of the original book fully up to date, incorporating the wealth of new knowledge and research of the last 30 years. It explores the evolution of complex forms of sex determination in insects, and the role of sexual selection in shaping the evolution of mating systems. Selection arising via male contest competition and female choice (both before and after copulation) are discussed, as are the roles of parasites and pathogens in mediating the strength of sexual selection, and the role that parental care plays in successful reproduction. The Evolution of Insect Mating Systems is suitable for both graduate students and researchers interested in insect mating systems or behaviour from an evolutionary, genetical, physiological, or ecological perspective. Due to its interdisciplinary and concept-driven approach, it will also be of relevance and use to a broad audience of evolutionary biologists.

As natural habitat continues to be lost and the world steadily becomes more urbanized, biologists are increasingly studying the effect this has on wildlife. Birds are particularly good model systems since their life history, behaviour, and physiology are especially influenced by directly measurable environmental factors such as light and sound pollution. It is therefore relatively easy to compare urban individuals and populations with their rural counterparts. This accessible text focuses on the behavioural and physiological mechanisms which facilitate adaptation and on the evolutionary process that ensues. It discusses topics such as acoustics, reproductive cues, disease, and artificial feeding, and includes a series of case studies illustrating cutting edge research on these areas. Avian Urban Ecology is suitable for professional avian biologists and ornithologists as well as graduate students of avian ecology, evolution, and conservation. It will also be of relevance and use to a more general audience of urban ecologists and conservation biologists.

In this pathbreaking and far-reaching work George Oster and Edward Wilson provide the first fully developed theory of caste evolution among the social insects. Furthermore, in studying the effects of natural selection in generally increasing the insects' ergonomic efficiency, they go beyond the concentration of previous researchers on the physiological mechanisms of the insects and turn our attention instead to the scale and efficiency of the insects' division of labor. Recognizing that the efficiency of the insect colony is based on a complex fitting of the division of labor to many simultaneous needs, including those imposed by the distribution of resources and enemies around the nest, Professors Oster and Wilson are able to construct a series of mathematical models to characterize the agents of natural selection that promote particular caste systems. The social insects play a key role in the subject of sociobiology because their social organization is so rigid and can be related to genetic evolution. Because of this important consideration, the authors' work has consequences not only for entomology but also for general evolutionary theory.

Arthropods as pests in crops, vectors of diseases, pollinators, and natural enemies of pests are of huge economic importance. They affect livestock, human health and food supplies around the world. This unique book examines and reviews how light and colour can be used to enhance pest management in agricultural and medical applications by manipulating the optical responses of arthropods. Arthropods use optical cues to find food, oviposition sites and to navigate. Light also regulates their diurnal and seasonal activities. Plants use optical cues to attract or deter various species of arthropod. In this book, an international team of experts show how light can be used successfully to attract, arrest, confuse and deter arthropods as well as to disrupt their biological clocks. The book: Presents an up-to-date and thorough summary of what is known about how arthropods of agricultural and medical importance respond to visual cues. Describes techniques that use light to manipulate pests and beneficial insects and mites. Presents a broad discussion of the potential use of optical manipulation of arthropods to improve the health of plants, domestic animals and humans.

One of the most interesting and vexing problems in ecology is how distinctly different communities of plants and animals can occur in the same ecosystem. The theory of these systems, known as multiple stable states, is well understood, but whether multiple stable states actually exist in nature has remained a hotly debated subject.
Multiple Stable States in Natural Ecosystems provides a broad and synthetic critique of recent advances in theory and new experimental evidence. Modern models of systems with multiple stable states are placed in historical context. Current theories are covered in a rigorous fashion with the specific goal of identifying testable predictions about multiple stable states. The book provides a more synthetic, more critical, and broader analysis of multiple stable states in natural ecosystems than any previous review. By making the theory more transparent and the analysis of the evidence more comparative, the book broadens the discussion about multiple stable states, leading to a more general consideration of the interplay between theory and experiment in community ecology and environmental management.
This accessible research monograph will be suitable for graduate students taking courses in community ecology, theoretical ecology, and restoration ecology. It will also be a valuable reference for professional ecologists and environmental managers requiring a concise overview of the topic.

Through a global and interdisciplinary lens, this book discusses, analyzes and summarizes the novel conservation approach of rewilding. The volume introduces key rewilding definitions and initiatives, highlighting their similarities and differences. It reviews matches and mismatches between the current state of ecological knowledge and the stated aims of rewilding projects, and discusses the role of human action in rewilding initiatives. Collating current scholarship, the book also considers the merits and dangers of rewilding approaches, as well as the economic and socio-political realities of using rewilding as a conservation tool. Its interdisciplinary nature will appeal to a broad range of readers, from primary ecologists and conservation biologists to land managers, policy makers and conservation practitioners in NGOs and government departments. Written for a scientifically literate readership of academics, researchers, students, and managers, the book also acts as a key resource for advanced undergraduate and graduate courses.

Marine and freshwater systems are being placed under pressure like never before. A bigger and more demanding human population has meant increased utilisation of aquatic systems and, as such, the need for sustainable solutions to allow the development and conservation of these systems has become an international priority. In order to understand the limits of exploitation, an understanding is needed of the ecological principles that constrain levels of productivity and the systems' responses to exploitation pressure. This timely book explores current exploitation practices, and the ecological basis and consequences of that exploitation. From a consideration of the ecological effects of the extraction of non-living resources, including energy and water itself, it progresses to the biology and ecology of aquatic organisms, and how these underpin the harvesting for aquatic resources. A discussion of the ecological consequences for the system of its use as a means of transport and as a repository for wastes follows, along with the increasing importance of aquatic systems for human recreational pursuits. Finally, effective management strategies for natural hazards, the provision of ecological goods and services, and restoration of aquatic systems are considered, as well as the importance of ecological science in exploitation management. The role of science in providing an understanding of the effects of human intervention in aquatic systems is emphasised throughout, along with a consideration of the role of ecology in the sustainable management of the consequences of human activity.

For the first time since the Neolithic, we have the opportunity to transform not only our food system but our entire relationship to the living world.

Farming is the world's greatest cause of environmental destruction - and the one we are least prepared to talk about. We criticise urban sprawl, but farming sprawls across thirty times as much land. We have ploughed, fenced and grazed great tracts of the planet, felling forests, killing wildlife, and poisoning rivers and oceans to feed ourselves. Yet millions still go hungry.

Now the food system itself is beginning to falter. But, as George Monbiot shows us in this brilliant, bracingly original new book, we can resolve the biggest of our dilemmas and feed the world without devouring the planet.

Regenesis is a breathtaking vision of a new future for food and for humanity. Drawing on astonishing advances in soil ecology, Monbiot reveals how our changing understanding of the world beneath our feet could allow us to grow more food with less farming. He meets the people who are unlocking these methods, from the fruit and vegetable grower revolutionising our understanding of fertility; through breeders of perennial grains, liberating the land from ploughs and poisons; to the scientists pioneering new ways to grow protein and fat. Together, they show how the tiniest life forms could help us make peace with the planet, restore its living systems, and replace the age of extinction with an age of regenesis.

Fish have evolved to colonise almost every type of aquatic habitat and today they are a hugely diverse group of over 25,000 species. The evolution of this great diversity of species has resulted in a myriad of solutions to the demands posed by the aquatic environment.
Ecological and Environmental Physiology of Fish presents a current and comprehensive overview of fish physiology to demonstrate how living fish function in their environment. As with other books in the Series, the emphasis is on the unique physiological characteristics of the fish, but with applications to questions of broad relevance in physiological ecology. A preliminary chapter introduces the aquatic environment and gives a general description of fish biology, evolution, and taxonomy. Subsequent sections discuss the particular problems of living in water, life in extreme environments, techniques for studying fish ecophysiology, and future research directions.

Global wetlands exhibit significant differences in both hydrology and species composition and range from moss-dominated arctic peatlands to seasonally-flooded tropical floodplains. They are increasingly recognized for the important services that they provide to both the environment and human society such as wildlife and fish production, nutrient filtering, and carbon sequestration. A combination of low oxygen levels and dense plant canopies present particular challenges for organisms living in this aquatic habitat. This concise textbook discusses the universal environmental and biological features of wetland habitats, with an emphasis on wetland plants and animals and their adaptations. It also describes the functional features of wetlands - primary production, litter decomposition, food webs, and nutrient cycling - and their significance locally and globally. The future of wetlands is examined, including the potential threats of global climate change and invasive species, as well as their restoration and creation. This new edition maintains the structure and style of the first, but is fully updated throughout with new chapters on invasive species, restoration/creation, global climate change, and the value of wetlands.

Just like humans, animals and plants suffer from infectious diseases, which can critically threaten biodiversity. This book describes key studies that have driven our understanding of the ecology and evolution of wildlife diseases. Each chapter introduces the host and disease, and explains how that system has aided our general understanding of the evolution and spread of wildlife diseases, through the development and testing of important epidemiological and evolutionary theories. Questions addressed include: How do hosts and parasites co-evolve? What determines how fast a disease spreads through a population? How do co-infecting parasites interact? Why do hosts vary in parasite burden? Which factors determine parasite virulence and host resistance? How do parasites influence the spread of invasive species? How do we control infectious diseases in wildlife? This book will provide a valuable introduction to students new to the topic, and novel insights to researchers, professionals and policymakers working in the field.

This book provides the first global synthesis of the biology of disturbed habitats and offers readers both the conceptual underpinnings and practical advice required to comprehend and address the unprecedented environmental challenges facing humans. Every habitat on earth has been impacted by natural disturbances such as volcanoes, earthquakes, landslides, fires, floods, and droughts. Humans have contributed many additional disturbances such as mining, urbanization, forestry, agriculture, fishing, and recreation. These anthropogenic disturbances modify and often exacerbate the effects of the natural disturbances. Together, they result in the abrupt loss of biomass or ecosystem structure and function to create denuded surfaces where novel mixtures of native and non-native microbes, plants, and animals establish, grow, and die. The Biology of Disturbed Habitats examines both natural and anthropogenic disturbances in aquatic and terrestrial habitats. It explores how nutrients and productivity are altered in the disturbed habitats, the effects of disturbance on biodiversity, and the spatial and temporal dynamics of organisms that colonize disturbed habitats. This book also addresses how to manage disturbances through appropriate conservation and restoration measures, and discusses how climate change and overpopulation now represent the most challenging disturbances at a global scale.

In nature there exist three main types of biotic interactions between individuals of different species: competition, predation, and mutualism. All three exert powerful selection pressures, and all three shape communities. However, the question of how important interspecific competition in nature really is remains controversial and unresolved. This book provides a critical and exhaustive review of the topic. Although the examples are limited mostly to birds (interspecific competition and community structure have been exhaustively studied in this animal group, and a lot of experimental data are available), the conclusions reached have a far broader relevance to population ecologists in general. The book reasons that the coexistence of species is the result of both past and presently on-going interspecific competition. Furthermore, understanding the importance of interspecific competition in natural systems will be increasingly important when modelling the effects of climate change on populations.

The genomics revolution has expanded from its origins in molecular biology to impact upon every discipline in the life sciences, including ecology. Several lines of ecological research can now be profitably addressed using genomics technology, including issues of nutrient cycling, population structure, life-history variation, trophic interaction, stress responses, and adaptation to environmental change. This new edition addresses a series of fundamental ecological questions: the relationship between community structure and ecological function in ecosystems; how variation in life-history patterns among species can be explained from interaction between the genome and the environment; the molecular responses to changing and toxic environmental conditions; adaptive phenotypes and their relationship to genetic variation. Each of these questions is evaluated in the light of recent advances in genomics research, paying particular attention to data obtained from sequencing and screening of environmental genomes (metagenomics), microarray-based transcription profiling, gene expression directed by signal-transduction pathways, and the analysis of genomic polymorphisms. The chapters covering these key areas are preceded by discussions of genomics methodology (including an overview of next-generation sequencing technologies) and comparative genomics, and the book concludes with a chapter on integrative approaches such as ecological control analysis. The authors also provide a comparative survey of the properties of genomes (genome size, gene families, synteny, and polymorphism) for prokaryotes as well as the main eukaryotic models. An Introduction to Ecological Genomics incorporates a balance of plant, animal, and microbial examples, and continues to define the new and exciting field of ecological genomics.

An essential introduction to microbiome science, a new cutting-edge discipline that is transforming the life sciences This book provides an accessible and authoritative guide to the fundamental principles of microbiome science, an exciting and fast-emerging new discipline that is reshaping many aspects of the life sciences. Resident microbes in healthy animals--including humans-can dictate many traits of the animal host. This animal microbiome is a second immune system conferring protection against pathogens; it can structure host metabolism in animals as diverse as reef corals and hibernating mammals; and it may influence animal behavior, from social recognition to emotional states. These microbial partners can also drive ecologically important traits, from thermal tolerance to diet, and have contributed to animal diversification over long evolutionary timescales. Drawing on concepts and data across a broad range of disciplines and systems, Angela Douglas provides a conceptual framework for understanding these animal-microbe interactions while shedding critical light on the scientific challenges that lie ahead. Douglas explains why microbiome science demands creative and interdisciplinary thinking-the capacity to combine microbiology with animal physiology, ecological theory with immunology, and evolutionary perspectives with metabolic science. An essential introduction to a cutting-edge field that is revolutionizing the life sciences, this book explains why microbiome science presents a more complete picture of the biology of humans and other animals, and how it can deliver novel therapies for many medical conditions and new strategies for pest control.

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.

Communication is an essential factor underpinning the interactions between species and the structure of their communities. Plant-animal interactions are particularly diverse due to the complex nature of their mutualistic and antagonistic relationships. However the evolution of communication and the underlying mechanisms responsible remain poorly understood.
Plant-Animal Communication is a timely summary of the latest research and ideas on the ecological and evolutionary foundations of communication between plants and animals, including discussions of fundamental concepts such as deception, reliability, and camouflage. It introduces how the sensory world of animals shapes the various modes of communication employed, laying out the basics of vision, scent, acoustic, and gustatory communication. Subsequent chapters discuss how plants communicate in these sensory modes to attract animals to facilitate seed dispersal, pollination, and carnivory, and how they communicate to defend themselves against herbivores. Potential avenues for productive theoretical and empirical research are clearly identified, and suggestions for novel empirical approaches to the study of communication in general are outlined.

Recommended in CHOICE, February 2021 Insects are all around us, outweighing humanity by 17 times. Many are nuisances; they compete with us for food and carry some of our most devastating diseases. Many common pests have been transported worldwide by humans. Yet, some recent reports suggest dramatic declines in some important groups, such as pollinators and detritivores. Should we care? Yes, we should. Without insect pollinators we'd lose 35% of our global food production; without detritivores, we would be buried in un-decayed refuse. Insects are also critical sources for nutritional, medical and industrial products. A world without insects would seem a very different and unpleasant place. So why do insects inspire such fear and loathing? This concise, full-color text challenges many entrenched perceptions about insect effects on our lives. Beginning with a summary of insect biology and ecology that affect their interactions with other organisms, it goes on to describe the various positive and negative ways in which insects and humans interact. The final chapters describe factors that affect insect abundance and approaches to managing insects that balance their impacts. The first textbook to cater directly to those studying Insect and Society or Insect Ecology modules, this book will also be fascinating reading for anyone interested in learning how insects affect human affairs and in applying more sustainable approaches to "managing" insects. This includes K-12 teachers, undergraduate students, amateur entomologists, conservation practitioners, environmentalists, as well as natural resource managers, land use planners and environmental policy makers.

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.
