In recent years it has become increasingly clear that chemical interactions play a fundamental role in aquatic habitats and have far-reaching evolutionary and ecological consequences. A plethora of studies have shown that aquatic organisms from most taxa and functional groups respond to minute concentrations of chemical substances released by other organisms. However, our knowledge of this "chemical network" is still negligible. Chemical interactions can be divided into two larger sub-areas based on the function of the chemical substance. First, there are interactions where chemical substances are toxic to other organisms and are used as a defence against consumers (including both herbivores and predators) or a weapon against competitors (allelopathy). Second, chemical substances may be used as a source for information of the environment; for example: how can I find the optimal habitat, the best food, the nicest partner, and avoid being eaten? Aquatic organisms are able to detect and respond to extremely low concentrations of chemical cues to answer all these questions. The book aims at connecting these intriguing chemical interactions with traditional knowledge of organism interactions. Chemical Ecology of Aquatic Systems covers a wide range of studies, both plant and animal, from different geographic regions and habitats - pelagic as well as benthic. Most of the chemical interactions are similar in freshwater and marine habitats and this book therefore strives at integrating work on both systems.
The origin of biological diversity, via the formation of new species, can be inextricably linked to adaptation to the ecological environment. Specifically, ecological processes are central to the formation of new species when barriers to gene flow (reproductive isolation) evolve between populations as a result of ecologically-based divergent natural selection. This process of 'ecological speciation' has seen a large body of particularly focused research in the last 10-15 years, and a review and synthesis of the theoretical and empirical literature is now timely. The book begins by clarifying what ecological speciation is, its alternatives, and the predictions that can be used to test for it. It then reviews the three components of ecological speciation and discusses the geography and genomic basis of the process. A final chapter highlights future research directions, describing the approaches and experiments which might be used to conduct that future work. The ecological and genetic literature is integrated throughout the text with the goal of shedding new insight into the speciation process, particularly when the empirical data is then further integrated with theory.
Animals that must hunt and kill for at least part of their living are inherently interesting to many people and the role that carnivores play in biological communities attract interest from ecologists and conservation biologists. Conflicts with human activities stimulate continual debates about the management of carnivore populations, and throughout the world people seek workable solutions for human/carnivore coexistence. This concise yet authoritative handbook describes research methods and techniques for the study and conservation of all terrestrial carnivore species. Particular attention is paid to techniques for managing the human/carnivore interface. Descriptions of the latest methodologies are supported by references to case studies, whilst dedicated boxes are used to illustrate how a technique is applied to a specific land cover type, species, or particular socio-economic context. The book describes the most recent advances in modelling the patterns of animal distributions, movements, and use of land cover types, as well as including the most efficient methods to trap, handle, and mark carnivores. Carnivores are biogeographically diverse and whilst extensive scientific research has investigated many aspects of carnivore biology, not all species have been equally covered. This book is unique in its intention to provide practical guidance for carrying out research and conservation of carnivores across all species and areas of the world.
Wind farms are an essential component of global renewable energy policy and the action to limit the effects of climate change. There is, however, considerable concern over the impacts of wind farms on wildlife, leading to a wide range of research and monitoring studies, a growing body of literature and several international conferences on the topic. This unique multi-volume work provides a comprehensive overview of the interactions between wind farms and wildlife. Volume 4 provides a state-of-the-science guide to monitoring and mitigation to minimise or even eliminate impacts on wildlife from offshore wind farms. The survey and monitoring section includes detailed chapters on fish and invertebrate communities, marine mammals and seabirds, and a chapter dedicated to the use of tracking technology applied to birds. The section continues with a chapter on collision risk and population modelling that underpins much current impact assessment, and a chapter detailing how collision risk for birds and bats may be monitored at sea. The mitigation section comprises chapters outlining mitigation options and strategies for birds and bats, and how to mitigate the effects of noise, especially during construction, on marine mammals and fish. A chapter on perspectives on marine spatial planning as applied to wind farms concludes the volume. The authors have been carefully selected from across the globe from the large number of academics, consultants and practitioners now engaged in wind farm studies, for their influential contribution to the science. Edited by Martin Perrow and with contributions by over 40 leading researchers including: Aonghais Cook, Thomas Dahlgren, Johann Koeppel, Meike Scheidat, Henrik Skov, Chris Thaxter & Frank Thomsen. The authors represent a wide range of organisations and institutions including the Universities of Gothenberg, Ghent, Highlands & Islands and Wageningen, Chalmers University of Technology and Technical University of Berlin, British Trust for Ornithology, The Carbon Trust, Institute of Avian Research Vogelwarte Helgoland, Institute for Applied Ecosystem Research (IfAOE), Norwegian Institute for Nature Research (NINA) and Sea Mammal Research Unit (SMRU); as well as several leading consultancies. Each chapter includes informative figures, tables, photographs and detailed case studies. Several of the latter are produced stand-alone from invited specialists to ensure geographic spread and to showcase exciting new research. This book is designed as the definitive guide on the topic for practitioners, researchers, managers and planners as well as students in higher education engaged in studies of the environment, ecology, climate change, conservation and impact assessment.

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.
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.
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.
A witty and informative account that busts the myths about Britain's most captivating butterfly species. When summer is at its zenith and the sallow foliage develops a bluish tinge, a giant butterfly – beautiful, bold and brazen – flies powerfully over the tree canopy. Females of this species, wary yet determined, haunt the sallow thickets, depositing their eggs, while the males establish treetop territories and descend to the woodland floor in search of indelicacies to feed upon. Mysterious, elusive and enthralling in equal measure, this is the butterfly that Victorian collectors yearned for above all others: His Imperial Majesty, the Purple Emperor. A wondrous enigma, the Purple Emperor is our most elusive and least-known butterfly – we glimpse it only through fissures in its treetop world, yet this giant insect has fascinated us for centuries and has even inspired its own 'Emperoring' language. Matthew Oates became captivated by the Purple Emperor following his first sighting as a boy. He has studied it assiduously ever since, devoting his life to trying to unravel the Emperor's secrets. His Imperial Majesty takes us on a journey, beginning with a dalliance into the bizarre history of our engagement with the butterfly, with daring doings and gross eccentricities from the Victorian and Edwardian eras. Subsequent chapters explore all aspects of this remarkable butterfly's life cycle, including behaviour, habitat preferences, life history and conservation, all relayed in Matthew's unique, informative and witty style. Not so long ago, our knowledge of the Emperor was largely based on a blend of mythology and assumption. This book dispels the fabrications and reveals all about the Purple Emperor – the king of British butterflies.
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.
Biogeography has renewed its concepts and methods following
important recent advances in phylogenetics, macroecology, and
geographic information systems. In parallel, the evolutionary
ecology of host-parasite interactions has attracted the interests
of numerous studies dealing with life-history traits evolution,
community ecology, and evolutionary epidemiology.

Birds have colonized almost every terrestrial habitat on the planet - from the poles to the tropics, and from deserts to high mountain tops. Ecological and Environmental Physiology of Birds focuses on our current understanding of the unique physiological characteristics of birds that are of particular interest to ornithologists, but also have a wider biological relevance. An introductory chapter covers the basic avian body plan and their still-enigmatic evolutionary history. The focus then shifts to a consideration of the essential components of that most fundamental of avian attributes: the ability to fly. The emphasis here is on feather evolution and development, flight energetics and aerodynamics, migration, and as a counterpoint, the curious secondary evolution of flightlessness that has occurred in several lineages. This sets the stage for subsequent chapters, which present specific physiological topics within a strongly ecological and environmental framework. These include gas exchange, thermal and osmotic balance, 'classical' life history parameters (male and female reproductive costs, parental care and investment in offspring, and fecundity versus longevity tradeoffs), feeding and digestive physiology, adaptations to challenging environments (high altitude, deserts, marine habitats, cold), and neural specializations (notably those important in foraging, long-distance navigation, and song production). Throughout the book classical studies are integrated with the latest research findings. Numerous important and intriguing questions await further work, and the book concludes with a discussion of methods (emphasizing cutting-edge technology), approaches, and future research directions.
Bioinvasions and Globalization synthesises our current knowledge of
the ecology and economics of biological invasions, providing an
in-depth evaluation of the science and its implications for
managing the causes and consequences of one of the most pressing
environmental issues facing humanity today.
Comprising a substantial part of living biomass on earth, ants are
integral to the functioning of terrestrial ecosystems. More than
12,500 species have been described to date, and it is estimated
that perhaps as many still await classification.
With up to a quarter of all insect species heading towards
extinction over the next few decades, there is now a pressing need
to summarize the techniques available for measuring insect
diversity in order to develop effective conservation strategies.

Community ecology is the study of the interactions between
populations of co-existing species. Co-edited by two prominent
community ecologists and featuring contributions from top
researchers in the field, this book provides a survey of the
state-of-the-art in both the theory and applications of the
discipline. It pays special attention to topology, dynamics, and
the importance of spatial and temporal scale while also looking at
applications to emerging problems in human-dominated ecosystems
(including the restoration and reconstruction of viable
communities).
Origins of Biodiversity is a unique introduction to the fields of macroevolution and macroecology, which explores the evolution and distribution of biodiversity across time, space and lineages. Using an enquiry-led framework to encourage active learning and critical thinking, each chapter is based around a case-study to explore concepts and research methods from contemporary macroevolution and macroecology. The book focuses on the process of science as much as the biology itself, to help students acquire the research skills and intellectual tools they need to understand and investigate the biological world around them. In particular, the emphasis on hypothesis testing encourages students to develop and test their own ideas. This text builds upon the foundations offered in most general introductory evolutionary biology courses to introduce an exciting range of ideas and research tools for investigating patterns of biodiversity.
This book is an essential reference source covering the chemical elements that are nutrients for plants or grazing animals. It deals with the concentrations and transformations of these elements in soils, grassland plants, and ruminant animals, particularly cattle and sheep. For each element, the following data are given: forms occurring in soil, factors that affect availability and concentration, uptake and distribution in grassland plants, role in animal nutrition, amounts and forms excreted by grazing animals, and concentrations needed by ruminant animals.
Biological invaders represent one of the primary threats to the
maintenance of global biodiversity, human health, and the success
of human economic enterprises. The continuing globalization of our
society ensures that the need to understand the process of
biological invasion will only increase in the future. There is also
a growing recognition that the study of biological invaders
provides a unique insight into basic questions in ecology and
evolution.
With the exception of climate change, biological invasions have
probably received more attention during the past ten years than any
other ecological topic. Yet this is the first synthetic,
single-authored overview of the field since Williamson's 1996 book.
Written fifty years after the publication of Elton's pioneering
monograph on the subject, Invasion Biology provides a comprehensive
and up-to-date review of the science of biological invasions while
also offering new insights and perspectives relating to the
processes of introduction, establishment, and spread. The book
connects science with application by describing the health,
economic, and ecological impacts of invasive species as well as the
variety of management strategies developed to mitigate harmful
impacts. The author critically evaluates the approaches, findings,
and controversies that have characterized invasion biology in
recent years, and suggests a variety of future research directions.
Carefully balanced to avoid distinct taxonomic, ecosystem, and
geographic (both investigator and species) biases, the book
addresses a wide range of invasive species (including protists,
invertebrates, vertebrates, fungi, and plants) which have been
studied in marine, freshwater, and terrestrial environments
throughout the world by investigators equally diverse in their
origins.
This new edition offers a concise but comprehensive introduction to
rocky shore ecology and has been completely revised and updated
throughout. It describes the diverse biota (invertebrates,
vertebrates, seaweeds, seagrasses and microalgae) that inhabit
rocky shores, and the factors that determine their distributions,
abundances and interactions. The book discusses the latest research
on processes that control community structure, utilizing a global
range of examples from a wide range of shore types - both temperate
and tropical. |
