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.
The Biogeography of Host-Parasite Interactions is the first book to integrate these two fields, using examples from a variety of host-parasite associations in various regions, and across both ecological and evolutionary timescales. Besides a strong theoretical component, there is a bias towards applications, specifically in the fields of historical biogeography, palaeontology, phylogeography, landscape epidemiology, invasion biology, conservation biology, human evolution, and health ecology. A particular emphasis concerns emerging and re-emerging infectious diseases linked to global changes.

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.
Ant Ecology explores key ecological issues and new developments in myrmecology across a range of scales. The book begins with a global perspective on species diversity in time and space, and examines interactions at the community level before describing the population ecology of these social insects. The final section covers the recent ecological phenomenon of invasive ants: how they move across the globe, invade, affect ecosystems, and are managed by humans. Each chapter links ant ecology to broader ecological principles, provides a succinct summary, and discusses future research directions. Practical aspects of myrmecology, applications of ant ecology, debates, and novel discoveries are highlighted in text boxes throughout the volume. The book concludes with a synthesis of the current state of the field and a look at exciting future research directions. The extensive reference list and full glossary are invaluable for researchers, and those new to the field.

The editors utilize their 50 years of combined experience in professional engagement with the behaviour and ecology of wild felids to draw together a unique network of the world's most respected and knowledgeable experts. For the first time, this inter-disciplinary research programme is brought together within a single volume.
Beginning with a complete account of all 36 felid species, there follow 8 comprehensive review chapters that span all the topics most relevant to felid conservation science, including evolution and systematics, felid form and function, genetic applications, behavioural ecology, management of species that come into conflict with people and control of international trade in felid species, conservation tools/techniques, ex situ management, and felid diseases. 19 detailed case studies then delve deeply into syntheses of the very best species investigations worldwide, written by all the leading figures in the field. These chapters portray the unique attributes of the wild felids, describe their fascinating (and conflicting) relationship with humans, and create an unparalleled platform for future research and conservation measures. A final chapter analyses the requirements of, and inter-disciplinary approaches to, practical conservation with cutting-edge examples of conservation science and action that go far beyond the cat family.

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.
Emergent zoonotic diseases such as HIV and SARS have already imposed major costs in terms of human health, whilst plant and animal pathogens have had similar effects on agriculture, forestry, fisheries. The introduction of pests, predators and competitors into many ecosystems has disrupted the benefits they provide to people, in many cases leading to the extirpation or even extinction of native species. This timely book analyzes the main drivers of bioinvasions - the growth of world trade, global transport and travel, habitat conversion and land use intensification, and climate change - and their consequences for ecosystem functioning. It shows how bioinvasions impose disproportionately high costs on countries where a large proportion of people depend heavily on the exploitation of natural resources. It considers the options for improving assessment and management of invasive species risks, and especially for achieving the international cooperation needed to address bioinvasions as a negative externality of international trade.

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).
Community Ecology: Processes, Models, and Applications adopts a mainly theoretical approach and focuses on the use of network-based theory, which remains little explored in standard community ecology textbooks. The book includes discussion of the effects of biotic invasions on natural communities; the linking of ecological network structure to empirically measured community properties and dynamics; the effects of evolution on community patterns and processes; and the integration of fundamental interactions into ecological networks. A final chapter indicates future research directions for the discipline.
FEATURES
* Incorporates the latest developments in the field and complements the existing textbook literature on community ecology
* Includes a mix of theoretical and applied chapters and a balance of emerging and established research topics
* Covers future research directions and provides ideal reference material for graduate courses in community ecology

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.
Insect Conservation outlines the main methods and techniques available to entomologists, providing a comprehensive synthesis for use by graduate students, researchers and practising conservationists worldwide. Both modern and more 'traditional' methodologies are described, backed up by practical background information and a global range of examples. Many newer techniques are included which have not yet been described in the existing book literature.
This book will be particularly relevant to postgraduate and advanced undergraduate students taking courses in insect ecology, conservation biology and environmental management, as well as established researchers in these fields. It will also be a valuable reference for nature conservation practitioners and professional entomologists worldwide.

Invasive alien species are a major and growing threat to biodiversity worldwide. The transport of organisms through increased levels of trade and tourism is leading to the widespread breaching of natural biogeographic barriers at unprecedented rates. Consequences can be severe, especially in naturally isolated ecosystems. Invasive alien species can cause the extinction of vulnerable endemic species, alter the structure and composition of communities, disrupt successional pathways, and lead to the loss of ecosystem services. Global climate change may further exacerbate the spread of alien species, as climatic zones shift and potential ranges alter.
The effective management of invasive alien species is clearly a priority for biological conservation worldwide. This book first provides strategies for managing such species at successive invasion stages, from prevention at the border to control of major infestations. It then describes the general tools and approaches that are recommended for successful management of particular groups of invasive organisms in a range of environments. In each case, the ecological basis and practical requirements of invasive alien species management are addressed.
This integration of proven techniques and policies will be useful to a wide readership of students, academics, conservation practitioners, invasive species managers, legislators, and to the broader community concerned with biological conservation.

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.
The study of exotic birds has had a particularly long history and has come to represent a fascinating intersection between the study of biological invasions, avian conservation biology, and basic principles of ecology and evolution. Avian Invasions summarizes and synthesizes this unique historical record and unravels the insights that the study of exotic birds brings to all three of these research strands. It includes chapters on the well-known contributions of exotic bird study to ecological science, and on the post-establishment evolution of introduced bird populations. The result is the most comprehensive picture yet of the invasion process.
Avian Invasions is aimed at professional avian biologists and ornithologists as well as graduate students of avian ecology, evolution and conservation. It also appeals to a more general audience of invasion ecologists.

'Predators are the best wildlife managers, ' writes George Schaller. They weed out the sick and old and keep herds healthy and alert. Yet the large predators of the world have been and are still being exterminated because they are thought to harm wildlife. Schaller's award-winning work, based on three years of study in the Serengeti National Park, describes the impact of the lion and other predators on the vast herds of wildebeest, zebra, and gazelle for which the area is famous.

The study of life in our universe has been given the name 'astrobiology'. It is a relatively new subject, but not a new discipline since it brings together several mature fields of science including astronomy, geology, biology, and climatology. An understanding of the singular conditions that allowed the only example of life that we know exists to emerge and survive on our turbulent planet is essential if we are to seek answers to two fundamental questions facing humanity: will life (and especially human life) continue on Earth, and does life exist elsewhere in the universe?
Astrobiology of Earth adopts a unique approach that differs from most texts in the field which focus on the possibility of extraterrestrial life. In contrast, the central theme of this book is the fortuitous combination of numerous cosmic factors that together produced the special environment which enabled the emergence, persistence and evolution of life on our own planet, culminating in humanity. This environment has been subject to constant and chaotic change during life's 3.6 billion year history. The geologically very recent appearance of humans and their effect on the biosphere is discussed in relation to its deterioration as well as climate change. The search for extraterrestrial life is considered with a view to the suggestion that humans may escape a depleted Earth by colonizing the universe.
This book contributes to our understanding of astrobiology from the perspective of life on Earth and especially human welfare and survival. Astronomical and geological phenomena are related in turn to their biological relevance and impact. This introductory text assumes little or no prior knowledge of morespecialized scientific fields and is designed for undergraduate and graduate level students taking related courses in departments of biology, earth science/geology, and environmental science. It will also serve as a useful biology primer for astronomy majors.

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.
The Biology of Rocky Shores begins by describing the shore environment, including the conditions caused by tidal rise and fall as well as an introduction to the effects of waves. It goes on to describe the biodiversity of the rocky shore environment, from seaweeds and cyanobacteria to starfish and oystercatchers, and some of the adaptations these organisms exhibit on the shore. The book discusses in turn the biology of primary producers, grazers, suspension feeders and predators, and the ways in which these trophic groups interact in various communities. The vertical and horizontal distributions of species in relation to the tidal cycle and wave exposure are also considered. The contributions that species make in determining how rocky-shore communities function, and how they interact with off-shore systems, are explored in detail. Human influences, notably pollution, over-fishing and the introduction of alien species, are discussed in the context of rocky shore conservation and future management strategies. A final chapter offers guidance on methods of study, techniques, and experimental approaches.
New to this Edition:
This second edition adds several dimensions to the first, by incorporating the expertise of two new authors, one based in Hong Kong, the other in USA. Since the original edition in 1996, views of how rocky shore communities are regulated have changed, and the book discusses these changes. It is no longer limited to the north-west Atlantic, but covers rocky shores worldwide. It discusses the diversity of shore organisms in terms of functional groups, and it now gives a detailed account of how organisms have adapted to the physical constraints of living on rocky shores. It provides advice on methods and experimental approaches. Black and white photographs and many new line drawings have been added to the original figures.
This new edition also feature 80% new text and 50% new illustrations.
Each of the books in the Oxford Biology of Habitats Series introduces a different habitat, and gives an integrated overview of the design, physiology, ecology, and behaviour of the organisms found there. The practical aspects of working within each habitat, the sorts of studies that are possible, and habitat biodiversity and conservation status are all explored.

Synthesizing studies of parental care in a wide variety of animals, this book is the first attempt to provide general answers to the following important questions: Why does the extent of parental care vary so widely between species? Why do only females care for eggs and young in some animals, only males in others, and both parents in a few? To what extent is parental care adjusted to variation in its benefits to offspring and its costs to parents? How do parents divide their resources between their sons and daughters? In this book separate chapters examine the evolution of variation in egg and neonate size, of viviparity and other forms of bearing, and of differences in the duration of incubation, gestation, and lactation. The book reviews theoretical and empirical predictions concerning the evolution of parental care and examines the extent to which these are supported by empirical evidence. The author examines the distribution of parental care among offspring, reviews the empirical evidence that parents invest to different extents in their sons and daughters, and discusses the degree to which parents manipulate the sex ratio of their progeny in relation to the availability of resources.

This advanced text focuses on the uses of distance sampling to estimate the density and abundance of biological populations. It addresses new methodologies, new technologies and recent developments in statistical theory and is the follow up companion to Introduction to Distance Sampling (OUP, 2001).
In this text, a general theoretical basis is established for methods of estimating animal abundance from sightings surveys, and a wide range of approaches to analysis of sightings data is explored. These approaches include: modelling animal detectability as a function of covariates, where the effects of habitat, observer, weather, etc. on detectability can be assessed; estimating animal density as a function of location, allowing for example animal density to be related to habitat and other locational covariates; estimating change over time in populations, a necessary aspect of any monitoring program; estimation when detection of animals on the line or at the point is uncertain, as often occurs for marine populations, or when the survey region has dense cover; survey design and automated design algorithms, allowing rapid generation of sound survey designs using geographic information systems; adaptive distance sampling methods, which concentrate survey effort in areas of high animal density; passive distance sampling methods, which extend the application of distance sampling to species that cannot be readily detected in sightings surveys, but can be trapped; and testing of methods by simulation, so that performance of the approach in varying circumstances can be assessed.

Robert May's seminal book has played a central role in the development of ecological science. Originally published in 1976, this influential text has overseen the transition of ecology from an observational and descriptive subject to one with a solid conceptual core. Indeed, it is a testament to its influence that a great deal of the novel material presented in the earlier editions has now been incorporated into standard undergraduate textbooks. It is now a quarter of a century since the publication of the second edition, and a thorough revision is timely.
Theoretical Ecology provides a succinct, up-to-date overview of the field set in the context of applications, thereby bridging the traditional division of theory and practice. It describes the recent advances in our understanding of how interacting populations of plants and animals change over time and space, in response to natural or human-created disturbance. In an integrated way, initial chapters give an account of the basic principles governing the structure, function, and temporal and spatial dynamics of populations and communities of plants and animals. Later chapters outline applications of these ideas to practical issues including fisheries, infectious diseases, tomorrow's food supplies, climate change, and conservation biology. Throughout the book, emphasis is placed on questions which as yet remain unanswered.
The editors have invited the top scientists in the field to collaborate with the next generation of theoretical ecologists. The result is an accessible, advanced textbook suitable for senior undergraduate and graduate level students as well as researchers in the fields of ecology, mathematical biology, environmental and resources management. It will also be of interest to the general reader seeking a better understanding of a range of global environmental problems.

Otters are highly charismatic and popular animals of very considerable concern to conservationists worldwide. Written by the pre-eminent authority in the field, this book builds on the reputation of the author's landmark monograph of the European otter, Wild Otters (OUP, 1995). Furthermore, its broader scope to include all species of otter in North America as well as Europe and elsewhere leads to a deeper synthesis that greatly expands the book's overall relevance and potential readership.
Aimed at naturalists, scientists and conservationists, its personal style and generously illustrated text will appeal to amateurs and professionals alike. It emphasizes recent research and conservation management initiatives for all 13 species of otter worldwide, incorporates recent molecular research on taxonomy and population genetics, and discusses the wider implications of otter studies for ecology and conservation biology.
As well as enchanting direct observations of the animals, there is guidance about how and where to watch and study them. From otters in the British and American lakes and rivers, to sea otters in the Pacific Ocean, giant otters in the Amazon and other species in Africa and Asia, this book provides an engaging approach to their fascinating existence, to the science needed to understand it, and to the very real threats to their survival.

Why are some kinds of organism species-rich and others species-poor? How do new species arise and why do some go extinct? Why do organisms grow and behave the way they do? This book provides an introduction to evolutionary ecology, the science that brings ecology and evolution together to help understand biological diversity. In a concise, readable format, Peter Mayhew covers the entire breadth of the subject, from life histories and the evolution of sex, to speciation and macroecology. Many emerging fields are also introduced, such as metabolic ecology, the evolution of population dynamics, and the evolution of global ecology. Discovering Evolutionary Ecology highlights the connections between these different subject areas, and for the first time paints a picture of a truly integrated field. It illustrates the research tools utilized, and demonstrates how advances in one area can spur on developments elsewhere when scientists combine evolutionary and ecological knowledge. To maximize accessibility, the book assumes only a basic knowledge of biology, includes a comprehensive glossary, and contains almost no maths. Each chapter provides suggestions for further reading, and there is also an extensive reference list. Ideal as an introduction to evolutionary ecology for undergraduates, this book will also interest established researchers, providing a broad and up-to-date context for their work.

Every three years a major international conference on bats draws the leading workers in the field to a carefully orchestrated presentation of the research and advances and current state of understanding of bat biology. Bats are the second most populous group of mammalia species, after rodents, and they are probably the most intensively studied group of mammals. Virtually all mammologists and a large proportion of organismic biologists are interested in bats. The earlier two edited books deriving from previous bat research conferences, as well as this one, have been rigorously edited by Tom Kunz and others, with all chapters subjected to peer review. The resulting volumes, published first by Academic Press and most recently by Smithsonian, have sold widely as the definitive synthetic treatments of current scientific understanding of bats.

Temporary waters are found throughout the world, and include intermittent streams and ponds, episodic rain puddles, seasonal limestone lakes, the water-retaining structures of plants, such as bromeliads and pitcher plants, and a variety of man-made container habitats. They are probably populated by various plant, animal, and microscopic communities ranging from the very simple to the highly complex. Temporary waters therefore represent fascinating and significant arenas in which to study the properties of species, as the latter deal with the rigours of living in highly variable environments. Obligate temporary water species display a remarkable array of adaptations to the periodic loss of their primary medium that largely set them apart from the inhabitants of permanent water bodies. Survival of individuals frequently depends upon exceptional physiological tolerance or effective migrational abilities that are timed to appropriate habitat phases. Quite apart from their inherent biological interest, temporary waters are now in the limelight from a conservation perspective as these habitats come more and more into conflict with human activities. Traditionally, many temporary waters (be they ponds, pools, streams, or wetlands) have been considered to be 'wasted' areas of land, potentially convertible to agriculture once drained. In reality, they are natural features of the global landscape that represent distinct and unique habitats for many species, some that are found nowhere else and others that reach their maximum abundance and/or genetic diversity there. Temporary waters are also very important from a human health perspective since they function as breeding places for the vectors of many disease organisms, including those that spread malaria, schistosomiasis, yellow fever, and dengue. Most of these exact a high toll in terms of global human suffering and reduced regional economies. This book collates and synthesises the highly scattered and diverse global literature on pure and applied aspects of these habitats and their biota. It examines the ecology of temporary waters in both natural and human environments, and seeks to identify common evolutionary themes. It will be of particular interest to aquatic ecologists, invertebrate and vertebrate biologists, environmental biologists, wetland managers and conservationists, those charged with controlling water-associated diseases, entomologists, educators, and natural historians.

The cuckoos are the most variable birds in social behavior and parental care: a few cuckoos are among the most social of all birds and rear their young in a common nest; most cuckoos are caring parents that rear their own young with some females laying a few eggs in the nests of others; while many cuckoo species are brood parasites who leave their eggs in the nests of other birds to rear, with their young maturing to kill their foster nestmates. In The Cuckoos, Robert B. Payne presents a new evolutionary history of the family based on molecular genetics, and uses the family tree to explore the origins and diversity of their behaviour. He traces details of the cuckoos' biology to their original sources, includes descriptions of previously unpublished field observations, and reveals new comparisons of songs showing previously overlooked cuckoo species. Lavishly illustrated with specially commissioned color plates and numerous maps, halftones, and line drawings, The Cuckoos provides the most comprehensive and up-to-date account of this family yet available.

For several years there has been a growing interest in understanding the dynamics of parasites in ecosystems, as well as the diversity of ways in which they influence ecosystem functioning through their effects on host populations and communities. Ecologists, epidemiologists, evolutionary biologists, and other scientists are increasingly coming to realise that parasites must be taken into account when studying ecosystems. Parasitism and Ecosystems summarizes current knowledge on this topic, providing a comprehensive overview for researchers and students. It represents the first synthesis of both the roles and the consequences of pathogens in ecosystems, utilizing well-documented case-studies to illustrate the main issues as well as identifying prospects for future research.
