More than 2600 species of tiger beetles are found all over the world. In North America there are 116 species of tiger beetle, divided into 153 geographically distinct races. Detailed studies of their natural history, population dynamics, communities, patterns of worldwide species richness, and taxonomy of particular subgroups have produced much information. Tiger beetles are among the most widely investigated groups of insects, especially in terms of their ecology and geographic distribution. The first edition of A Field Guide to the Tiger Beetles of the United States and Canada, published in 2005, has served as a field and natural-history guide to all known species of tiger beetles found in North America above the Mexican border. The 2nd edition is a pleasant and comprehensible handbook of the identification, distribution, natural history, and habitat details of the 116 species of tiger beetles in North America. The updated handbook provides new information including observations of seasonality, range extensions and biology, a newly developed list of common names, and twenty-five artistically pleasing identification color plates. The second edition of A Field Guide to the Tiger Beetles of the United States and Canada provides essential information to recognize and easily identify tiger beetles for established naturalists and outdoor enthusiasts alike.

Brown Trout is an iconic species inhabiting a diversity of habitats from mountain streams of transparent waters to lakes and oceans and is sought after by thousands of passionate anglers worldwide. This book summarizes the important aspects of brown trout s biology and ecology. It includes several chapters focused on the impact caused by the species and on potential management strategies to, first, maintain numerous damaged populations within their natural distributional range and, second, ameliorate its impacts on exotic environments. Authors from all over the world involved in their study and management offer reviews and case studies that provide insight into theory and practice. Brown Trout: Biology, Ecology and Management will provide scientists, researchers and experts in salmonids with attempts to uncover the exit from the complex maze of controversies and challenges associated with this species.

Animals lead rich social lives. They care for one another, compete for resources, and mate. Within a society, social relationships may be simple or complex and usually vary considerably, both between different groups of individuals and over time. These social systems are fundamental to biological organization, and animal societies are central to studies of behavioral and evolutionary biology. But how do we study animal societies? How do we take observations of animals fighting, grooming, or forming groups and produce a realistic description or model of their societies?
"Analyzing Animal" "Societies "presents a conceptual framework for analyzing social behavior and demonstrates how to put this framework into practice by collecting suitable data on the interactions and associations of individuals so that relationships can be described, and, from these, models can be derived. In addition to presenting the tools, Hal Whitehead illustrates their applicability using a wide range of real data on a variety of animal species--from bats and chimps to dolphins and birds. The techniques that Whitehead describes will be profitably adopted by scientists working with primates, cetaceans, birds, and ungulates, but the tools can be used to study societies of invertebrates, amphibians, and even humans. "Analyzing Animal" "Societies "will become a standard reference for those studying vertebrate social behavior and will give to these studies the kind of quality standard already in use in other areas of the life sciences.

The application and interpretation of statistics are central to ecological study and practice. Ecologists are now asking more sophisticated questions than in the past. These new questions, together with the continued growth of computing power and the availability of new software, have created a new generation of statistical techniques. These have resulted in major recent developments in both our understanding and practice of ecological statistics. This novel book synthesizes a number of these changes, addressing key approaches and issues that tend to be overlooked in other books such as missing/censored data, correlation structure of data, heterogeneous data, and complex causal relationships. These issues characterize a large proportion of ecological data, but most ecologists' training in traditional statistics simply does not provide them with adequate preparation to handle the associated challenges. Uniquely, Ecological Statistics highlights the underlying links among many statistical approaches that attempt to tackle these issues. In particular, it gives readers an introduction to approaches to inference, likelihoods, generalized linear (mixed) models, spatially or phylogenetically-structured data, and data synthesis, with a strong emphasis on conceptual understanding and subsequent application to data analysis. Written by a team of practicing ecologists, mathematical explanations have been kept to the minimum necessary. This user-friendly textbook will be suitable for graduate students, researchers, and practitioners in the fields of ecology, evolution, environmental studies, and computational biology who are interested in updating their statistical tool kits. A companion web site provides example data sets and commented code in the R language.

The first book to highlight research done by women of color in the field of shark science. A special emphasis is placed on amplifying the voices of Black, Indigenous, People of Color as well as artisanal fishers and economically disadvantaged coastal communities. Accessible to younger readers too, encouraging school children to get into marine science. Covers a broad range of topics including biology, ecology and evolution as well as some less talked about topics like outreach and stakeholder engagement. Interdisciplinary approach to shark science and conservation Easily digestible content for non-experts Focuses on a charismatic group of animals, sharks Offers diverse perspectives and cutting-edge research while diving into issues regarding the decolonization of shark science and changing public perception of sharks. This is an opportunity to challenge the notion that there is only one type of scientist or that scientists look and think a certain way.

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.

In recent years researchers have discovered that bats play key roles in many ecosystems as insect predators, seed dispersers, and pollinators. Bats also display astonishing ecological and evolutionary diversity and serve as important models for studies of a wide variety of topics, including food webs, biogeography, and emerging diseases. In "Bat Ecology," world-renowned bat scholars present an up-to-date, comprehensive, and authoritative review of this ongoing research.
The first part of the book covers the life history and behavioral ecology of bats, from migration to sperm competition and natural selection. The next section focuses on functional ecology, including ecomorphology, feeding, and physiology. In the third section, contributors explore macroecological issues such as the evolution of ecological diversity, range size, and infectious diseases (including rabies) in bats. A final chapter discusses conservation challenges facing these fascinating flying mammals.
"Bat Ecology" is the most comprehensive state-of-the-field collection for scientists and researchers.

Ants are probably the most dominant insect group on Earth, representing ten to fifteen percent of animal biomass in terrestrial ecosystems. Flowering plants, meanwhile, owe their evolutionary success to an array of interspecific interactions--such as pollination, seed dispersal, and herbivory--that have helped to shape their great diversity. "The Ecology and Evolution of Ant-Plant Interactions" brings together findings from the scientific literature on the coevolution of ants and plants to provide a better understanding of the unparalleled success of these two remarkable groups, of interspecific interactions in general, and ultimately of terrestrial biological communities.
"The Ecology and Evolution of Ant-Plant Interactions" synthesizes the dynamics of ant-plant interactions, including the sources of variation in their outcomes. Victor Rico-Gray and Paulo S. Oliveira capture both the emerging appreciation of the importance of these interactions within ecosystems and the developing approaches that place studies of these interactions into a broader ecological and evolutionary context. The collaboration of two internationally renowned scientists, "The Ecology and Evolution of Ant-Plant Interactions" will become a standard reference for understanding the complex interactions between these two taxa.

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.

Peatlands form important landscape elements in many parts of the world and play significant roles for biodiversity and global carbon balance. This new edition has been fully revised and updated, documenting the latest advances in areas such as microbial processes and relations between biological processes and hydrology. As well as thoroughly referencing the latest research, the authors expose a rich older literature where an immense repository of natural history has accumulated. The Biology of Peatlands starts with an overview of the main peatland types (marsh, swamp, fen, and bog), before examining the entire range of biota present (microbes, invertebrates, plants, and vertebrates), together with their specific adaptations to peatland habitats. Detailed coverage is devoted to the genus Sphagnum, the most important functional plant group in northern peatlands, although tropical and southern hemisphere peatlands are also covered. Throughout the book the interactions between organisms and environmental conditions (especially wetness, availability of oxygen, and pH) are emphasized, with chapters on the physical and chemical characteristics of peat, the role of peat as an archive of past vegetation and climate, and peatland succession and development. Several other key factors and processes are then examined, including hydrology and nutrient cycling. The fascinating peatland landforms in different parts of the world are described, together with theories on how they have developed. Human interactions with peatlands are considered in terms of management, conservation, and restoration. A final chapter, new to this edition, focuses on the role of peatlands as sources or sinks for the greenhouse gases carbon dioxide and methane, and the influences of climate change on peatlands. This timely and accessible text is suitable for students and researchers of peatland ecology, as well as providing an authoritative overview for professional ecologists and conservation biologists.

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.

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.

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.

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.

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.
