This book assesses Alaskan wolf and bear management programs from scientific and economic perspectives. Relevant factors that should be taken into account when evaluating the utility of such programs are identified. The assessment includes a review of current scientific knowledge about the dynamics and management of large mammalian predatorprey relationships and human harvest of wildlife in northern ecosystems, and an evaluation of the extent to which existing research and management data allow prediction of the outcome of wolf management or control programs and grizzly bear management programs. Included is an evaluation of available economic studies and methodologies for estimating the costs and benefits of predator control programs in Alaska.

Our highly seasonal world restricts insect activity to brief portions of the year. This feature necessitates a sophisticated interpretation of seasonal changes and enactment of mechanisms for bringing development to a halt and then reinitiating it when the inimical season is past. The dormant state of diapause serves to bridge the unfavourable seasons, and its timing provides a powerful mechanism for synchronizing insect development. This book explores how seasonal signals are monitored and used by insects to enact specific molecular pathways that generate the diapause phenotype. The broad perspective offered here scales from the ecological to the molecular and thus provides a comprehensive view of this exciting and vibrant research field, offering insights on topics ranging from pest management, evolution, speciation, climate change and disease transmission, to human health, as well as analogies with other forms of invertebrate dormancy and mammalian hibernation.

This book presents the discoveries made during nearly three decades of research on the parental shield bug, Parastrachia japonensis inhabiting Kyushu Island, Japan. P. japonensis has evolved a unique and fascinating life history, characterized by extreme behavioral and physiological adaptations that have culminated in a singularly dependent relationship with its lone host tree, Schoepfia jasminodora (Olacaceae), which is a generally scarce and unreliable resource. It is expected that the evolution of parental care behaviors in the strictly semelparous P. japonensis was more directly influenced by the benefit to females that arises from enhanced survivorship of current offspring, rather than any possible cost the females might incur in terms of reduced future reproductive success, because no future reproduction is possible. The authors explain how the different parental cares in this species enhance offspring survivorship in the context of the ecological conditions it has experienced over evolutionary time. The book begins with a recap of the earliest studies, the reports through 1991, and then introduces the many fascinating aspects of the life history, neurobiology, physiology and behavior of P. japonensis that have been newly discovered since, and those aspects that have been confirmed through experimentation over the past thirty years. This comprehensive review of information will be useful for comparative studies of parental care in other semelparous and iteroparous organisms experiencing both similar and different ecological constraints. The book will be of academic interest to undergraduate and graduate students of entomology, zoology, behavior, and behavioral ecology.

The edited book covers the climate change impact broadly across the ecosystems including increasing pressure on livelihood and food supplies to the society. Climate change, in particular, rising temperatures, can have both direct and indirect effects on global fish production. Fisheries and aquaculture is one of the important sectors of agriculture for livelihood and nutritional security. Fish, being poikilothermic in nature are very sensitive to any change in the ecosystem. In commercial aquaculture, it is crucial to ensure that environmental rearing conditions are adequate, if not optimal, for fish growth, welfare and profitability. Thus, the book develops an understanding regarding changes in relevant environmental parameters and its affect in the growth and physiological performance of fish. Fish feeds on natural food organisms, but the adverse changes in the ecosystem attracts nutritionists to provide better food and feeding strategies for optimum growth and survival of the fish. it is become necessary to develop preparedness about the changes and their mitigation strategies through fish nutrition and feeding strategies. This book addresses the potential impact of climate change on the aquaculture sector under sections - Assessment of Global Warming Impact on aquatic resources and fish production, Adaptation in Fish Digestive Physiology and Biochemistry under Changing Environment, Prioritization of fish feed technology with respect to changing climate for adaptation and mitigation, Strategies and planning on reproductive physiology and feed management for biodiversity conservation. The chapters are contributed by the experts in the field of fish nutrition and physiology. The book assists fish farmers, entrepreneurs, planners and advisors specifically related to nutritional and physico-biochemical changes in fishes to adapt or mitigate the adverse effect of climate change.

This book discusses the increase in number and capacity of wind farms in Germany and how this is affecting birds of prey. Several methods are used to study the behaviour of birds of prey in relation to wind farms, including telemetry data, field observations, and comparisons of turbine base areas. Special attention is given to the effects on different bird species and the impact wind farms may have on population growth and breeding success of birds of prey. Chapter 6 discusses the collision risks at wind turbines and provides an analysis of the fatalities. In the concluding chapter, ideas are put forward to help minimize conflicts, estimate risks, and offer practical recommendations for future research. This book will be of interest to wind farm developers, researchers, applied ecologists and landscape planners.

Caribbean coral reefs have unique species, are the world’s second largest coral reef community, and the most threatened. This book will be of major interest to all concerned with saving coral reefs from extinction. No other book available shows Caribbean coral reefs when they were at their best. It is only by comparing the images in this book with what they see now that people can recognize what we have lost. It is far more than they can imagine! Those who did not see it themselves can only do so through this book. Jim Porter’s insightful commentary in the Foreword adds crucial scientific perspective. Other books do not provide a one volume summary of all the major species on the Caribbean reef. This book is also more accurate in important systematic organization than other books in this field. The author’s excellent photographs convey clear concepts of processes and key aspects of species for identification. The book is written in an engaging story-telling style, yet clearly and concisely communicating the essential scientific concepts. Whereas most books have chapters dividing up one topic, this book is divided into different kinds of information which are essential to understanding coral reefs: how reefs are structured, corals, invertebrates, fishes, cryptic or hidden organisms, the community at night and others. One review states "After 52 years of researching coral reefs, I find this is the best book to present what reefs should be like, and were like 50 years ago. It is also written in a style accessible to recreational divers who wish to know the organisms, processes, and structures they are seeing." Another says "The first thing that will strikes the reader is the exquisite photography. There are many great underwater photographers, but the author is in a class by himself. Once the first impact of the astounding photography is accepted, the reader will be struck by what might be called the scientific integrity of the book." While this book is 'a time machine' taking the reader back to when these reefs thrived, there is optimism that we may see these reefs again as they appear in this book.

Reintroduction of Fish and Wildlife Populations provides a practical step-by-step guide to successfully planning, implementing, and evaluating the re-establishment of animal populations in former habitats or their introduction in new environments. In each chapter, experts in reintroduction biology outline a comprehensive synthesis of core concepts, issues, techniques, and perspectives. This manual and reference supports scientists and managers from fisheries and wildlife professions as they plan reintroductions, initiate releases of individuals, and manage restored populations over time. Covering a broad range of taxonomic groups, ecosystems, and global regions, this edited volume is an essential guide for academics, students, and professionals in natural resource management.

Insects provide excellent model systems for understanding evolutionary ecology. They are abundant, small and relatively easy to rear, and these traits facilitate both field and laboratory experiments. This book has been developed from the Royal Entomological Society's 22nd International Symposium, held in Reading in 2003. Topics include speciation and adaptation; life history, phenotype plasticity and genetics; sexual selection and reproductive biology; insect-plant interactions; insect-natural enemy interactions and social insects.

Falcons are stunning and iconic birds. Australia has six falcon species, with two endemic to the continent and two others endemic to the Australasian region. They are important indicators of the health of our ecosystems, due to their position at the top of the food chain. But several species are declining, with two species threatened in some states. In Australian Falcons: Ecology, Behaviour and Conservation, Dr Stephen Debus provides a 30-year update of knowledge on these six species, as well as a falcon-like hawk, the Black-shouldered Kite. This book is based partly on the author's field studies, as well as being a supplement to the Handbook of Australian, New Zealand and Antarctic Birds (HANZAB) and recent global treatises. It offers up-to-date information on the Australian species, including their behaviours, ecology and biology. It reviews their population status and threats, and suggests what needs to be done to ensure the future of these spectacular birds. Australian Falcons is an invaluable resource for raptor biologists, birdwatchers, wildlife rescuers and carers, raptor rehabilitators and zookeepers. FEATURES Covers the biology, ecology, behaviour, conservation and management of the six falcon species, and one falcon-like hawk. Reviews the population status and threats of the Australian falcons. First comprehensive book on Australian falcons since the 1993 publication of HANZAB Volume 2. Features striking colour photos by photographer David Whelan.

Symbiosis in Fishes provides comprehensive coverage of the biology of partnerships between fishes and invertebrates, ascending the phylogenetic scale, from luminescent bacteria, sponges and coelenterates to molluscs, crustaceans and echinoderms. Both facultative and obligatory partnerships are reviewed with emphasis on the behavioral, ecological and evolutionary aspects of fish symbiosis. Each of the eight chapters of this book focuses on a different group of partners. The structure, physiology and anti-predatory strategies of each group are described to provide the necessary background for the understanding of their partnerships with fishes. The formation of the associations, the degree of partner specificity and its regulation, as well as the benefits and costs for the fishes and their associates, communication between partners and their possible co-evolution are discussed in each chapter. This is the first attempt to critically review in a single volume all associations of fishes with invertebrates based on the latest studies in these areas, together with studies published many years ago and little cited since then. Symbiosis in Fishes provides a huge wealth of information that will be of great use and interest to many life scientists including fish biologists, ecologists, ethologists, aquatic scientists, physiologists and evolutionary biologists. It is hoped that the contents of the book will stimulate many to further research, to fill in the gaps in our knowledge in this fascinating and important subject. Libraries in all universities and research establishments where biological sciences are studied and taught should have copies of this exciting book.

We shriek about them, slap and spray them, and generally think of insects (when we think of them at all) as pests. Yet, if all insects, or even a critical few, were to disappear--if there were none to pollinate plants, serve as food for other animals, dispose of dead organisms, and perform other ecologically essential tasks--virtually all the ecosystems on earth, the webs of life, would unravel. This book, the first to catalogue ecologically important insects by their roles, gives us an enlightening look at how insects work in ecosystems--what they do, how they live, and how they make life as we know it possible.

In "What Good Are Bugs?" Gilbert Waldbauer combines anecdotes from entomological history with insights into the intimate workings of the natural world, describing the intriguing and sometimes amazing behavior of these tiny creatures. He weaves a colorful, richly textured picture of beneficial insect life on earth, from ants sowing their "hanging gardens" on Amazonian shrubs and trees to the sacred scarab of ancient Egypt burying balls of cattle dung full of undigested seeds, from the cactus-eating caterpillar (aptly called "Cactoblastis") controlling the spread of the prickly pear to the prodigious honey bee and the "sanitary officers of the field"--the fly maggots, ants, beetles, and caterpillars that help decompose and recycle dung, carrion, and dead plants. As entertaining as it is informative, this charmingly illustrated volume captures the full sweep of insects' integral place in the web of life.

Tracking Animal Migration with Stable Isotopes, Second Edition, provides a complete introduction to new and powerful isotopic tools and applications that track animal migration, reviewing where isotope tracers fit in the modern toolbox of tracking methods. The book provides background information on a broad range of migration scenarios in terrestrial and aquatic systems and summarizes the most cutting-edge developments in the field that are revolutionizing the way migrant individuals and populations are assigned to their true origins. It allows undergraduates, graduate students and non-specialist scientists to adopt and apply isotopes to migration research, and also serves as a useful reference for scientists. The new edition thoroughly updates the information available to the reader on current applications of this technique and provides new tools for the isotopic assignment of individuals to origins, including geostatistical multi-isotope approaches and the ways in which researchers can combine isotopes with routine data in a Bayesian framework to provide best estimates of animal origins. Four new chapters include contributions on applications to the movements of terrestrial mammals, with particular emphasis on how aspects of animal physiology can influence stable isotope values.

This book presents the facet theoretical framework as a tool for facilitating the conception of complex animal behaviour research and the design of research procedures through employing mapping sentences. Using the facet theoretical framework, this book takes a holistic view of bird behaviour. Components of bird behavior are identified and then reassembled to facilitate an understanding of the behaviour in the context of its natural occurrence. This provides new insight on both the parts of the behaviour and how these interact as a whole. The multi-faceted approach to designing, evaluating and understanding bird behavior presented offers a template that is adaptable for investigating a wide variety of avian species and different forms of behaviour. Behavioural biologists, animal and comparative psychologists, other natural and behavioural scientists, as well as students of these disciplines will find this book to be an interesting and enlightening read.

From foraging patterns in a single tree to social interactions across a home range, how primates use space is a key question in the field of primate behavioral ecology. Drawing on the latest advances in spatial analysis tools, this book offers practical guidance on applying geographic information systems (GIS) to central questions in primatology. An initial methodological section discusses niche modelling, home range analysis and agent-based modelling, with a focus on remote data collection. Research-based chapters demonstrate how ecologists apply this technology to a suite of topics including: calculating the intensity of use of both range and travel routes, assessing the impacts of logging, mining and hunting, and informing conservation strategies.

Mixed-Species Groups of Animals: Behavior, Community Structure, and Conservation presents a comprehensive discussion on the mixed-species groups of animals, a spectacular and accessible example of the complexity of species interactions. They are found in a wide range of animals, including invertebrates, fish, mammals and birds, and in different habitats, both terrestrial and aquatic, throughout the world. While there are more than 500 articles on this subject scattered in separate categories of journals, there has yet to be a general, cross-taxa book-length introduction to this subject that summarizes the behavior and community structure of these groups. The authors first survey the diversity of spatial associations among animals and then concentrate on moving groups. They review the major classes of theories that have been developed to explain their presence, particularly in how groups increase foraging efficiency and decrease predation. Finally, they explore the intricacies of species interactions, such as communication, that explain species roles in groups and discuss what implications these social systems have for conservation.

Begins with in-depth coverage of wildlife behavior concepts as they relate to conservation problems. Topics will focus principally on discussion, critique, and development of behavioral concepts, with particular attention given to published studies on various topics in wildlife behavioral concepts as related to conservation and natural history. He will include an extensive list of references.

Wood ants play an ecologically dominant and conspicuous role in temperate boreal forests, making a keystone contribution to woodland ecosystem functions and processes. Wood ant taxonomy and global distributions set the scene for this text's exploration of wood ants as social insects, examining their flexible social structures, genetics, population ecology, and behaviour, from nest-mate recognition to task allocation. Wood ants' interactions with their environment and with other organisms are essential to their success: competition, predation and mutualism are described and analysed. Bringing together the expertise of ecological researchers and conservation practitioners, this book provides practical and theoretical advice about sampling and monitoring these insects, and outlines the requirements for effective conservation. This is an indispensable resource for wood ant researchers, entomologists, conservationists and ecological consultants, as well as anyone interested in social insects, keystone species and the management and conservation of forest ecosystems.

Human-wildlife conflict (HWC) is one of the most complex and urgent issues facing wildlife management and conservation today. Originally focused on the ecology and economics of wildlife damage, the study and mitigation of HWC has gradually expanded its scope to incorporate the human dimensions of the whole spectrum of human-wildlife relationships, from conflict to coexistence. Having the conflict-to-coexistence continuum as its leitmotiv, this book explores a variety of theories and methods currently used to address human-wildlife interactions, illustrated by case studies from around the world. It presents some key concepts in the field, such as values, emotions, social identity and tolerance, and a variety of insights and solutions to turn conflict into coexistence, from individual level to national scales, including conservation marketing, incremental and radical innovation, strategic planning, and socio-ecological systems. This volume will be of interest to a wide range of readers, including academics, researchers, students, practitioners and policy-makers.

This book presents the whole picture of the ecological and evolutionary study on the ground beetle group, the subgenus Ohomopterus of the genus Carabus, endemic to Japan. This flightless beetle group consists of many geographic races. They show divergence in key traits for reproductive isolation-body size and genital morphology, which leads to coexistence of two or more species. This beetle group provides an important material to study how a lineage of organisms diversify and form multi-species assemblage, and thereby multiply their species richness. The book introduces novel genomic approaches to resolve questions about evolution of Ohomopterus. The readers will find that this story of evolution in Carabus beetles revealed by recent approaches is much different from what was told in previous literature. Exploring different cases across a wide range of lineages is important in constructing a synthetic theory of species radiation and richness, including speciation and species coexistence. This study on Ohomopterus beetles contributes to the ongoing discussion to understand how and why species multiply and how species richness increases in one area of our planet.

Australian Deserts: Ecology and Landscapes is about the vast sweep of the Outback, a land of expanses making up three-quarters of the continent - the heart of Australia. Steve Morton brings his extensive first-hand knowledge and experience of arid Australia to this book, explaining how Australian deserts work ecologically. This book outlines why unpredictable rainfall and paucity of soil nutrients underpin the nature of desert ecosystems, while also describing how plants and animals came to be desert dwellers through evolutionary time. It shows how plants use uncertain rainfall to provide for persistence of their populations, alongside outlines of the dominant animals of the deserts and explanations of the features that help them succeed in the face of aridity and uncertainty. Richly illustrated with the photographs of Mike Gillam, this fascinating and accessible book will enhance your understanding of the nature of arid Australia. FEATURES: Describes how Australian deserts work ecologically and how plants and animals came to be desert dwellers through evolutionary time. Outlines two key features of arid Australia, uncertain rainfall and paucity of soil nutrients, that underpin the nature of its ecosystems. Shows how plants use uncertain rainfall to provide for persistence of their populations. Outlines the dominant animals of the deserts and explains the features that help them succeed in the face of aridity and uncertainty. Features stunning images by renowned photographer Mike Gillam.

The Action Plan for Australian Birds 2020 is the most comprehensive review of the status of Australia's avifauna ever attempted. The latest in a series of action plans for Australian birds that have been produced every decade since 1992, it is also the largest. The accounts in this plan have been authored by more than 300 of the most knowledgeable bird experts in the country, and feature far more detail than any of the earlier plans. This volume also includes accounts of over 60 taxa that are no longer considered threatened, mainly thanks to sustained conservation action over many decades. This extensive book covers key themes that have emerged in the last decade, including the increasing impact of climate change as a threatening process, most obviously in Queensland's tropical rainforests where many birds are being pushed up the mountains. However, the effects are also indirect, as happened in the catastrophic fires of 2019/20. Many of the newly listed birds are subspecies confined to Kangaroo Island, where fire destroyed over half the population. But there are good news stories too, especially on islands where there have been spectacular successes with predator control. Such uplifting results demonstrate that when action plans are followed by action on the ground, threatened species can indeed be recovered and threats alleviated. FEATURES: Provides an overview of the conservation status of all Australian birds in 2020, including birds not yet threatened but known to be declining. Includes readily accessible status information for each species with reasons for listing and distribution maps. Outlines the actions needed for conservation and describes many birds where conservation action has allowed downlisting because they are now secure. Identifies the birds most threatened by the 2019/20 fires and draws attention to the broader role climate change is now playing in bird declines.

These charismatic mammals, which include dogs, cats, hyenas, weasels, mongooses, seals, sea lions and bears, have always held special importance to humans throughout history and continue to do so today. In recent decades, the emergence of new technologies has completely transformed our knowledge of how carnivorans interact with their environments and consequently reshaped our view of carnivoran ecology. This unique synthesis uses examples from a diverse and expanding carnivoran literature, drawing from all carnivoran families and spanning the world's oceans and continents, to produce a clearly written and richly illustrated book that reviews our current state of knowledge of carnivoran ecology. It addresses all levels of biological organization and function, from genes to enzymes, organisms, populations, and ecosystems. Special attention is given to how carnivoran species interact with their prey, each other, and humans. There is an emphasis on community interactions and their importance in carnivoran evolution, showing how evolutionary constraints (morphological, physiological, and behavioral) structure communities today. The book's approach is strongly comparative, contrasting herbivores with carnivores, predators with scavengers, and cats with dogs. Carnivorans play important roles in many high-profile conservation cases, either as species of concern or agents of endangerment, and their importance is demonstrated in both contexts. Carnivoran Ecology is an accessible advanced textbook aimed principally at senior undergraduate and graduate students taking courses in carnivore ecology, as well as a broad audience of professional academics (especially carnivore and mammalian biologists), researchers, and practitioners working in both governmental and non-governmental organizations. A significant secondary market will exist amongst the large amateur naturalist community including those wishing to explore the ecological and evolutionary links between domestic carnivorans (dogs, cats, ferrets etc.) and their wild counterparts.

Much as Rachel Carson's "Silent Spring" was a call to action against the pesticides that were devastating bird populations, Charles S. Elton's classic "The Ecology of Invasions by Animals and Plants" sounded an early warning about an environmental catastrophe that has become all too familiar today--the invasion of nonnative species. From kudzu to zebra mussels to Asian long-horned beetles, nonnative species are colonizing new habitats around the world at an alarming rate thanks to accidental and intentional human intervention. One of the leading causes of extinctions of native animals and plants, invasive species also wreak severe economic havoc, causing $79 billion worth of damage in the United States alone.
Elton explains the devastating effects that invasive species can have on local ecosystems in clear, concise language and with numerous examples. The first book on invasion biology, and still the most cited, Elton's masterpiece provides an accessible, engaging introduction to one of the most important environmental crises of our time.
Charles S. Elton was one of the founders of ecology, who also established and led Oxford University's Bureau of Animal Population. His work has influenced generations of ecologists and zoologists, and his publications remain central to the literature in modern biology.
"History has caught up with Charles Elton's foresight, and "The Ecology of Invasions" can now be seen as one of the central scientific books of our century."--David Quammen, from the Foreword to "Killer Algae: The True Tale of a Biological Invasion"
