This practical handbook of reptile field ecology and conservation brings together a distinguished, international group of reptile researchers to provide a state-of-the-art review of the many new and exciting techniques used to study reptiles. The authors describe ecological sampling techniques and how they are implemented to monitor the conservation status and population trends of snakes, lizards, tuatara, turtles, and crocodilians throughout the world. Emphasis is placed on the extent of statistical inference and the biases associated with different techniques and analyses. The chapters focus on the application of field research and data analysis for achieving an understanding of reptile life history, population dynamics, movement patterns, thermal ecology, conservation status, and the relationship between reptiles and their environment. The book emphasises the need for thorough planning, and demonstrates how a multi-dimensional approach incorporates information related to morphology, genetics, molecular biology, epidemiology, statistical modelling, animal welfare, and biosecurity. Although accentuating field sampling, sections on experimental applications in laboratories and zoos, thermal ecology, genetics, landscape ecology, disease and biosecurity, and management options are included. Much of this information is scattered in the scientific literature or not readily available, and the intention is to provide an affordable, comprehensive synthesis for use by graduate students, researchers, and practising conservationists worldwide.

Fish are one of the most important global food sources, supplying a significant share of the world's protein consumption. From stocks of wild Alaskan salmon and North Sea cod to entire fish communities with myriad species, fisheries require careful management to ensure that stocks remain productive, and mathematical models are essential tools for doing so. Fish Ecology, Evolution, and Exploitation is an authoritative introduction to the modern size- and trait-based approach to fish populations and communities. Ken Andersen covers the theoretical foundations, mathematical formulations, and real-world applications of this powerful new modeling method, which is grounded in the latest ecological theory and population biology. He begins with fundamental assumptions on the level of individuals and goes on to cover population demography and fisheries impact assessments. He shows how size- and trait-based models shed new light on familiar fisheries concepts such as maximum sustainable yield and fisheries selectivity-insights that classic age-based theory can't provide-and develops novel evolutionary impacts of fishing. Andersen extends the theory to entire fish communities and uses it to support the ecosystem approach to fisheries management, and forges critical links between trait-based methods and evolutionary ecology. Accessible to ecologists with a basic quantitative background, this incisive book unifies the thinking in ecology and fisheries science and is an indispensable reference for anyone seeking to apply size- and trait-based models to fish demography, fisheries impact assessments, and fish evolutionary ecology.

Over the last decade, molecular studies carried out on the Australasian biota have revealed a new world of organic structure that exists from submicroscopic to continental scale. Furthermore, in studies of global biogeography and evolution, DNA sequencing has shown that many large groups, such as flowering plants, passerine birds and squamates, have their basal components in this area. Using examples ranging from kangaroos and platypuses to kiwis and birds of paradise, the book examines the patterns of distribution and evolution of Australasian biodiversity and explains them with reference to tectonic and climatic change in the region. The surprising results from molecular biogeography demonstrate that an understanding of evolution in Australasia is essential for understanding the development of modern life on Earth. A milestone in the literature on this subject, this book will be a valuable source of reference for students and researchers in biogeography, biodiversity, ecology and conservation.

Before the birth of modern insecticides, farmers and gardeners used predatory and parasitic wasps and flies, insect-eating birds, lizards and toads as agents of biological control. In the late 19th century sugar cane scientists carried cane toads from Barbados to Puerto Rico, to Hawai'i and then Queensland to control pests. Toads were introduced to some 138 countries, and are now ranked among the world's most invasive species. Queensland's sugar scientists released the toad into cane fields in 1935. They were supported by cane growers, politicians, the nation's leading scientists, the premier of Queensland and the prime minister of Australia. Only a lone voice objected. In the following 70 years they spread as far as western NSW and Western Australia. This story is about good intentions, unintended consequences and of simple acts leading to catastrophic outcomes. It is about scientists so committed to solving a problem, serving their country, their leaders and the industry that employed them, that they are blinkered to adverse impacts. There are lessons to learn from the toad's tale. And as the tale shows, we still come perilously close to repeating the mistakes of the past.

Temperature affects everything. It influences all aspects of the physical environment and governs any process that involves a flow of energy, setting boundaries on what an organism can or cannot do. This novel textbook reveals the key principles behind the complex relationship between organisms and temperature, namely the science of thermal ecology. It starts by providing a rigorous framework for understanding the flow of energy in and out of the organism, before describing the influence of temperature on what organisms can do and how fast they can do it. With these fundamental principles covered, the bulk of the book explores thermal ecology itself, incorporating the important extra dimension of interactions with other organisms. An entire chapter is devoted to the crucially important subject of how organisms are responding to climate change. Indeed, the threat of rapid climatic change on a global scale is a stark reminder of the challenges that remain for evolutionary thermal biologists, and adds a sense of urgency to this book's mission.

The illegal trade in live apes, ape meat and body parts occurs across all ape range states and poses a significant and growing threat to the long-term survival of wild ape populations worldwide. What was once a purely subsistence and cultural activity, now encompasses a global multi-million-dollar trade run by sophisticated trans-boundary criminal networks. The challenge lies in teasing apart the complex and interrelated factors that drive the ape trade, while implementing strategies that do not exacerbate inequality. This volume of State of the Apes brings together original research and analysis with topical case studies and emerging best practices, to further the ape conservation agenda around killing, capture and trade. This title is also available as Open Access via Cambridge Core.

Featuring forty-seven original essays by seventy leading researchers, Primates in Perspective, Second Edition, offers a comprehensive and contemporary overview of all major areas of primatology. Thoroughly revised and updated throughout, the second edition offers a diversity of theoretical positions on such topics as reproduction, ecology, and social behavior and intelligence.
Primates in Perspective, Second Edition, is ideal for introductory primatology courses and can also be used in upper-division behavior and conservation courses. Additionally, it is an essential reference for primate researchers.

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.

Microbial ecology is the study of interactions among microbes in natural environments and their roles in biogeochemical cycles, food web dynamics, and the evolution of life. Microbes are the most numerous organisms in the biosphere and mediate many critical reactions in elemental cycles and biogeochemical reactions. Because they are essential players in the carbon cycle and related processes, microbial ecology is a vital science for understanding the role of the biosphere in global warming and the response of natural ecosystems to climate change. This second edition has been fully revised, restructured, and updated while remaining concise and accessible. It discusses the major processes carried out by viruses, bacteria, fungi, protozoa and other protists - the microbes - in freshwater, marine, and terrestrial ecosystems. The focus is on biogeochemical processes, starting with primary production and the initial fixation of carbon into cellular biomass, before exploring how that carbon is degraded in both oxygen-rich (oxic) and oxygen-deficient (anoxic) environments. These processes are in turn affected by ecological interactions, including competition for limiting nutrients, viral lysis, and predation by various protists in soils and aquatic habitats. The book neatly connects processes occurring at the micron scale to events happening at the global scale, including the carbon cycle and its connection to climate change issues. A final chapter is devoted to symbiosis and other relationships between microbes and larger organisms. Microbes have huge impacts not only on biogeochemical cycles, but also on the ecology and evolution of more complex forms of life, including humans.

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.

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.

The bonobo, along with the chimpanzee, is one of our two closest living relatives. Their relatively narrow geographic range (south of the Congo River in the Democratic Republic of Congo) combined with the history of political instability in the region, has made their scientific study extremely difficult. In contrast, there are dozens of wild and captive sites where research has been conducted for decades with chimpanzees. Because data sets on bonobos have been so hard to obtain and so few large-scale studies have been published, the majority of researchers have treated chimpanzee data as being representative of both species. However, this misconception is now rapidly changing. With relative stability in the DRC for over a decade and a growing community of bonobos living in zoos and sanctuaries internationally, there has been an explosion of scientific interest in the bonobo with dozens of high impact publications focusing on this fascinating species. This research has revealed exactly how unique bonobos are in their brains and behavior, and reminds us why it is so important that we redouble our efforts to protect the few remaining wild populations of this iconic and highly endangered great ape species.

Mexico is the fourteenth largest country in the world and ranks fifth in biodiversity. Located in the transition zone between the temperate and tropical regions of North and South America, Mexico is an important migratory corridor for wildlife and also provides wintering habitat for several species of bats, monarch butterflies, and temperate North American nesting birds. Mexico faces several challenges to wildlife management and conservation efforts. While there is increased public education and acknowledgment of the valuable benefits wildlife provides, there is still much work to do to incentivize conservation efforts. Fortunately, there is growing recognition that Mexico's wildlife resources can be a critical component in the rural economic development of the country. Bringing together an international team of wildlife experts across North America, Wildlife Ecology and Management in Mexico provides information on the status, distribution, ecological relationships, and habitat requirements and management of the most important game birds and mammals in Mexico. It also reviews current threats and challenges facing wildlife conservation as well as strategies for resolving these issues. This reference is a valuable tool for wildlife biologists, wildlife management professionals, and anyone interested in conserving Mexico's wealth of natural resources. By laying out the challenges to conservation research, editors Raul Valdez and J. Alfonso Ortega-S. hope to encourage interdisciplinary communication and collaboration across borders.

The number of primates on the brink of extinction continues to grow, and the need to respond with effective conservation measures has never been greater. This book provides a comprehensive and state-of-the-art synthesis of research principles and applied management practices for primate conservation. It begins with a consideration of the biological, intellectual, economic, and ecological importance of primates and a summary of the threats that they face, before going on to consider these threats in more detail with chapters on habitat change, trade, hunting, infectious diseases, and climate change. Potential solutions in the form of management practice are examined in detail, including chapters on conservation genetics, protected areas, and translocation. An Introduction to Primate Conservation brings together an international team of specialists with wide-ranging expertise across primate taxa. This is an essential textbook for advanced undergraduates, graduate students, and established researchers in the fields of primate ecology and conservation biology. It will also be a valuable reference for conservation practitioners, land managers, and professional primatologists worldwide.

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.

Tropical East Asia is home to over one billion people and faces massive human impacts from its rising population and rapid economic growth. It has already lost more than half of its forest cover to agriculture and urbanization, and has the highest rates of deforestation and logging in the tropics. Habitat loss, coupled with hunting and the relentless trade in wildlife products, threatens all its large and many of its smaller vertebrates. Despite these problems, the region still supports an estimated 15-25% of global terrestrial biodiversity and a growing environmental awareness means that it is no longer assumed that economic development justifies environmental damage, and no longer accepted that this trade-off is inevitable. Effective conservation action now depends on integrating a clear understanding of the ecological patterns and processes in the region with the varied needs of its human population. This third edition continues to provide an overview of the terrestrial ecology of Tropical East Asia: from southern China to Indonesia, and from Bhutan and Bangladesh to the Ryukyu Islands of Japan. It retains the balance between compactness and comprehensiveness of the previous editions, and the even-handed geographical treatment of the whole region, but it updates both the contents and the perspective. Approximately one third of the text is new or greatly modified, reflecting the explosion of new research in the region in the last few years and the increasing use of new tools, particularly from genomics and remote sensing. The change in perspective largely reflects the growing realization that we are in a new epoch, the Anthropocene, in which human activities have at least as large an influence as natural processes, and that stopping or reversing ecological change is no longer an option. This does not mean that biodiversity conservation is no longer possible or worthwhile, but that the biodiverse future we strive for will inevitably be very different from the past. The Ecology of Tropical East Asia is an advanced textbook suitable for senior undergraduate and graduate level students taking courses on the terrestrial ecology of the East Asian tropics, as well as an authoritative regional reference for professional ecologists, conservationists, and interested amateurs worldwide.

"Cheetahs of the Serengeti Plains" is the most comprehensive account of carnivore social behavior to date. Synthesizing more than a decade of research in the wild, this book offers a detailed account of the behavior and ecology of cheetahs. Compared with other large cats, and other mammals, cheetahs have an unusual breeding system; whereas lions live in prides and tigers are solitary, some cheetahs live in groups while others live by themselves. Tim Caro explores group and solitary living among cheetahs and discovers that the causes of social behavior vary dramatically, even within a single species.
Why do cheetah cubs stay with their mother for a full year after weaning? Why do adolescents remain in groups? Why do adult males live in permanent associations with each other? Why do adult females live alone? Through observations on the costs and benefits of group living, Caro offers new insight into the complex behavior of this extraordinary species. For example, contrary to common belief about cooperative hunting in large carnivores, he shows that neither adolescents nor adult males benefit from hunting in groups.
With many surprising findings, and through comparisons with other cat species, Caro enriches our understanding of the evolution of social behavior and offers new perspectives on conservation efforts to save this charismatic and endangered carnivore.

How do animals communicate using sounds? How did animal vocal communication arise and evolve? Exploring a new way to conceptualize animal communication, this new edition moves beyond an earlier emphasis on the role of senders in managing receiver behaviour, to examine how receivers' responses influence signalling. It demonstrates the importance of the perceiver role in driving the evolution of communication, for instance in mimicry, and thus shifts the emphasis from a linguistic to a form/function approach to communication. Covering a wide range of animals from frogs to humans, this new edition includes new sections on human prosodic elements in speech, the vocal origins of smiles and laughter and deliberately irritating sounds and is ideal for researchers and students of animal behaviour and in fields such as sensory biology, neuroscience and evolutionary biology.

Many infectious diseases of recent concern, including malaria, cholera, plague, and Lyme disease, have emerged from complex ecological communities, involving multiple hosts and their associated parasites. Several of these diseases appear to be influenced by human impacts on the environment, such as intensive agriculture, clear-cut forestry, and habitat loss and fragmentation; such environmental impacts may affect many species that occur at trophic levels below or above the host community. These observations suggest that the prevalence of both human and wildlife diseases may be altered in unanticipated ways by changes in the structure and composition of ecological communities. Predicting the epidemiological ramifications of such alteration in community composition will require strengthening the current union between community ecology and epidemiology. Disease Ecology highlights exciting advances in theoretical and empirical research towards understanding the importance of community structure in the emergence of infectious diseases. To date, research on host-parasite systems has tended to explore a limited set of community interactions, such as a community of host species infected by a single parasite species, or a community of parasites infecting a single host. Less effort has been devoted to addressing additional complications, such as multiple-host-multiple-parasite systems, sequential hosts acting on different trophic levels, alternate hosts with spatially varying interactions, effects arising from trophic levels other than those of hosts and parasites, or stochastic effects resulting from small population size in at least one alternate host species. The chapters in this book illustrate aspects of community ecology that influence pathogen transmission rates and disease dynamics in a wide variety of study systems. The innovative studies presented in Disease Ecology communicate a clear message: studies of epidemiology can be approached from the perspective of community ecology, and students of community ecology can contribute significantly to epidemiology.

Globalization is a multidimensional issue, and its impacts on world resources cross and integrate environmental, economic, political and cultural boundaries. Over the last few decades, the push towards globalization has brought a new dimension in which managers of fisheries and water resources will need to operate, both at the local and global level of governance. In order to effectively address the future sustainability of these resources, it is critical to understand the driving factors of globalization and their effect on fisheries ecosystems and the people who depend on these resources for their cultural and societal well-being. This 2007 book discusses the social and political changes affecting fisheries, the changes to ecological processes due to direct and indirect impacts of globalization, the changing nature of the goods and services that fisheries ecosystems are able to provide, and the resultant changes in markets and economic assessment of our fishery resources.

Nematodes are the most widespread multicellular animals in nature and analysis of nematodes in terrestrial, freshwater and marine environments, as well as their role and function in ecosystems, can be used for environmental monitoring. Compared to other organisms, they offer the greatest potential as bioindicators and can be used to study gene expression in relation to environmental challenges, to monitor changing impacts on the environment and in laboratory ecotoxicity tests. This volume will address classical and molecular approaches to nematode community analysis, the contemporary field of nematodes as biosensors, as well as geonomic and post geonomic aspects of nematode bioindicators. In addition, case studies will stress the importance of these bioindicators and demonstrate the commercial potential of these technologies. Providing a timely review of research into nematodes and environmental monitoring, this book will be essential reading for researchers in nematology and environmental science.

Every year, countless juvenile Pacific salmon leave streams andrivers on their migration to feeding grounds in the North Pacific Oceanand the Bering Sea. After periods ranging from a few months to severalyears, adult salmon enter rivers along the coasts of Asia and NorthAmerica to spawn and complete their life cycle. Within this generaloutline, various life history patterns, both among and within species,involve diverse ways of exploiting freshwater, estuarine, and marinehabitats. There are seven species of Pacific salmon. Five (coho,chinook chum, pink, and sockeye) occur in both North America and Asia.Their complex life histories and spectacular migrations have longfascinated biologists and amateurs alike. Physiological Ecology of Pacific Salmon providescomprehensive reviews by leading researchers of the physiologicaladaptations that allow Pacific Salmon to sustain themselves in thediverse environments in which they live. It begins with an analysis ofenergy expenditure and continues with reviews of locomotion, growth,feeding, and nutrition. Subsequent chapters deal with osmoticadjustments enabling the passage between fresh and salt water, nitrogenexcretion and regulation of acid-base balance, circulation and gastransfer, and finally, responses to stress. This thorough and authoritative volume will be a valuable referencefor students and researchers of biology and fisheries science as theyseek to understand the environmental requirements for the perpetuationof these unique and valuable species.
