Insect Conservation: A Global Synthesis is a landmark, field-defining work written by Professor Michael Samways, one of the founding fathers of this burgeoning discipline of conservation science. This book presents a state-of-the-art, comprehensive review of the entire field of insect conservation, from single-species conservation to whole-ecosystem approaches, and from natural ecosystems to the urban landscape. The variety and number of insects are truly vast. They are the most speciose group of organisms on Earth, with the majority barely known to science or still not described at all. They are a vital component in all terrestrial ecosystems, which would fail to function normally without them. Insect populations worldwide, however, are under threat. Human-mediated degradation of natural habitats, pollution, over-use of pesticides, and the spread of urbanization has led to the collapse of insect populations in many areas of the world. A growing recognition of the importance of insects in natural and agricultural systems has stimulated the development of an entire discipline dedicated to their conservation. Insect Conservation: A Global Synthesis is designed to be used by students of conservation biology and ecology, but also serves as an essential overview for professional entomologists with an interest in conservation, and for conservationists interested in insects. The book communicates on three levels: (i) through the text, with extensive references providing a gateway to the ever-increasing primary literature; (ii) through the extensive use of carefully constructed illustrations, with detailed captions which act to summarize the text and are complete in their own right; and (iii) through focused key points at the end of every chapter, which summarise the main learning points for students.
This monumental text-reference places in clear persepctive the importance of nutritional assessments to the ecology and biology of ruminants and other nonruminant herbivorous mammals. Now extensively revised and significantly expanded, it reflects the changes and growth in ruminant nutrition and related ecology since 1982. Among the subjects Peter J. Van Soest covers are nutritional constraints, mineral nutrition, rumen fermentation, microbial ecology, utilization of fibrous carbohydrates, application of ruminant precepts to fermentive digestion in nonruminants, as well as taxonomy, evolution, nonruminant competitors, gastrointestinal anatomies, feeding behavior, and problems fo animal size. He also discusses methods of evaluation, nutritive value, physical struture and chemical composition of feeds, forages, and broses, the effects of lignification, and ecology of plant self-protection, in addition to metabolism of energy, protein, lipids, control of feed intake, mathematical models of animal function, digestive flow, and net energy. Van Soest has introduced a number of changes in this edition, including new illustrations and tables. He places nutritional studies in historical context to show not only the effectiveness of nutritional approaches but also why nutrition is of fundamental importance to issues of world conservation. He has extended precepts of ruminant nutritional ecology to such distant adaptations as the giant panda and streamlined conceptual issues in a clearer logical progression, with emphasis on mechanistic causal interrelationships. Peter J. Van Soest is Professor of Animal Nutrition in the Department of Animal Science and the Division of Nutritional Sciences at the New York State College of Agriculture and Life Sciences, Cornell University.
Fishes have evolved to colonise almost every type of aquatic habitat and today they are a hugely diverse group of over 25,000 species. The evolution of this great diversity of species has resulted in a myriad of solutions to the demands posed by the aquatic environment. Ecological and Environmental Physiology of Fishes presents a current and comprehensive overview of fish physiology to demonstrate how living fishes function in their environment. As with other books in the Series, the emphasis is on the unique physiological characteristics of the fish, but with applications to questions of broad relevance in physiological ecology. A preliminary chapter introduces the aquatic environment and gives a general description of fish biology, evolution, and taxonomy. Subsequent sections discuss the particular problems of living in water, life in extreme environments, techniques for studying fish ecophysiology, and future research directions.
The North American freshwater fish fauna is the most diverse and thoroughly researched temperate fish fauna in the world. "Ecology of North American Freshwater Fishes" is the only textbook to provide advanced undergraduate and graduate students and researchers with an up-to-date and integrated view of the ecological and evolutionary concepts, principles, and processes involved in the formation and maintenance of this fauna. "Ecology of North American Freshwater Fishes" provides readers with a broad understanding of why specific species and assemblages occur in particular places. Additionally, the text explores how individuals and species interact with each other and with their environments, how such interactions have been altered by anthropogenic impacts, and the relative success of efforts to restore damaged ecosystems. This book is designed for use in courses related to aquatic and fish ecology, fish biology, ichthyology, and related advanced ecology and conservation courses, and is divided into five sections for ease of use. Chapter summaries, supplemental reading lists, online sources, extensive figures, and color photography are included to guide readers through the material and facilitate student learning. Part 1: Faunal origins, evolution, and diversity Presents a broad picture - both spatially and temporally - of the derivation of the fauna, including global and regional geological and climatological processes and their effects on North American fishes. Part 2: Formation, maintenance, and persistence of local populations and assemblages. Focuses on how local fish populations and assemblages are formed and how they persist, or not, through time. Part 3: Form and function Deals with the relationship of body form and life history patterns as they are related to ecological functions. Part 4: Interactions among individuals and species Discusses the numerous interactions among individuals and species through communication, competition, predation, mutualism, and facilitation. Part 5: Issues in conservation. Focuses on several primary conservation issues such as flow alterations and the increasing biotic homogenization of faunas.
Aphids are tempting subjects for investigation because they are often abundant, easily found, and unlikely to run away, and because of intriguing facts about their biology such as polyphenism, parthenogenesis, gall formation, and the production of a soldier morph. However, until now identification has presented a severe challenge to the beginner, because there are so many rather similar species, many of which have several different forms. The authors make this much-needed Naturalists' Handbook accessible by confining themselves to aphids living on broad-leaved trees. This has reduced the problems of identification to manageable proportions and should encourage more field studies of this important and ubiquitous group of insects. This is a digital reprint (without updates) of ISBN 9780855463144 (2007).
"Monitoring Plant and Animal Populations" is a thorough overview of
monitoring issues. It is designed for field biologists and land
managers with a modest statistical background. The authors have
written a practical text that will include concrete guidelines for
ecologists to follow to design a statistically defensible
monitoring program for natural populations and communities. Features
How did rodent outbreaks in Germany help to end World War I? What caused the destructive outbreak of rodents in Oregon and California in the late 1950s, the large population outbreak of lemmings in Scandinavia in 2010, and the great abundance of field mice in Scotland in the spring of 2011? Population fluctuations, or outbreaks, of rodents constitute one of the classic problems of animal ecology, and in "Population Fluctuations in Rodents", Charles J. Krebs sifts through the last eighty years of research to draw out exactly what we know about rodent outbreaks and what should be the agenda for future research. Krebs has synthesized the research in this area, focusing mainly on the voles and lemmings of the Northern Hemisphere - his primary area of expertise - but also referring to the literature on rats and mice. He covers the patterns of changes in reproduction and mortality and the mechanisms that cause these changes - including predation, disease, food shortage, and social behavior - and discusses how landscapes can affect population changes, methodically presenting the hypotheses related to each topic before determining whether or not the data supports them. He ends on an expansive note, by turning his gaze outward and discussing how the research on rodent populations can apply to other terrestrial mammals. Geared toward advanced undergraduates, graduate students, and practicing ecologists interested in rodent population studies, this book will also appeal to researchers seeking to manage rodent populations and to understand outbreaks in both natural and urban settings - or, conversely, to protect endangered species.
This book describes a powerful and flexible technique for the modeling of behavior, based on evolutionary principles. The technique employs stochastic dynamic programming and permits the analysis of behavioral adaptations wherein organisms respond to changes in their environment and in their own current physiological state. Models can be constructed to reflect sequential decisions concerned simultaneously with foraging, reproduction, predator avoidance, and other activities. The authors show how to construct and use dynamic behavioral models. Part I covers the mathematical background and computer programming, and then uses a paradigm of foraging under risk of predation to exemplify the general modeling technique. Part II consists of five "applied" chapters illustrating the scope of the dynamic modeling approach. They treat hunting behavior in lions, reproduction in insects, migrations of aquatic organisms, clutch size and parental care in birds, and movement of spiders and raptors. Advanced topics, including the study of dynamic evolutionarily stable strategies, are discussed in Part III.
Curriculum in Action: Multiculturalism and the Human-Animal Connection introduces future and current K-12 educators to engaging animal themes and fosters the consideration and development of animal-focused lessons. The text illuminates the multifaceted roles animals have played in society, their cultural influences within diverse communities, and how teachers can introduce animal themes in the classroom in an empathetic, ethical, and considerate way. Each chapter is organized according to world locale, revealing cultural perceptions regarding animals on each continent, presenting readers with an overview of current research, and providing lessons and activities with emphasis on the STEAM approach to learning and focus on Next Generation Science Standards. Readers learn about the relationships people have had with animals over time and how those relationships have transformed through environmental changes. The text also examines environment-dependent interactions that humans have with companion animals, as well as how these special interactions can improve our connections with others. Curriculum in Action is an ideal resource for courses and programs with focus on K-12 education. It is also an excellent resource for teachers who are interested in incorporating animal themes into their curriculum.
The fascinating and complex evolutionary relationship of the monarch butterfly and the milkweed plant Monarch butterflies are one of nature's most recognizable creatures, known for their bright colors and epic annual migration from the United States and Canada to Mexico. Yet there is much more to the monarch than its distinctive presence and mythic journeying. In Monarchs and Milkweed, Anurag Agrawal presents a vivid investigation into how the monarch butterfly has evolved closely alongside the milkweed--a toxic plant named for the sticky white substance emitted when its leaves are damaged--and how this inextricable and intimate relationship has been like an arms race over the millennia, a battle of exploitation and defense between two fascinating species. The monarch life cycle begins each spring when it deposits eggs on milkweed leaves. But this dependency of monarchs on milkweeds as food is not reciprocated, and milkweeds do all they can to poison or thwart the young monarchs. Agrawal delves into major scientific discoveries, including his own pioneering research, and traces how plant poisons have not only shaped monarch-milkweed interactions but have also been culturally important for centuries. Agrawal presents current ideas regarding the recent decline in monarch populations, including habitat destruction, increased winter storms, and lack of milkweed--the last one a theory that the author rejects. He evaluates the current sustainability of monarchs and reveals a novel explanation for their plummeting numbers. Lavishly illustrated with more than eighty color photos and images, Monarchs and Milkweed takes readers on an unforgettable exploration of one of nature's most important and sophisticated evolutionary relationships.
Ecology is capturing the popular imagination like never before, with issues such as climate change, species extinctions, and habitat destruction becoming ever more prominent. At the same time, the science of ecology has advanced dramatically, growing in mathematical and theoretical sophistication. Here, two leading experts present the fundamental quantitative principles of ecology in an accessible yet rigorous way, introducing students to the most basic of all ecological subjects, the structure and dynamics of populations. John Vandermeer and Deborah Goldberg show that populations are more than simply collections of individuals. Complex variables such as distribution and territory for expanding groups come into play when mathematical models are applied. Vandermeer and Goldberg build these models from the ground up, from first principles, using a broad range of empirical examples, from animals and viruses to plants and humans. They address a host of exciting topics along the way, including age-structured populations, spatially distributed populations, and metapopulations. This second edition of "Population Ecology" is fully updated and expanded, with additional exercises in virtually every chapter, making it the most up-to-date and comprehensive textbook of its kind.Provides an accessible mathematical foundation for the latest advances in ecologyFeatures numerous exercises and examples throughoutIntroduces students to the key literature in the fieldThe essential textbook for advanced undergraduates and graduate studentsAn online illustration package is available to professors
Animals do have culture, maintains this delightfully illustrated and provocative book, which cites a number of fascinating instances of animal communication and learning. John Bonner traces the origins of culture back to the early biological evolution of animals and provides examples of five categories of behavior leading to nonhuman culture: physical dexterity, relations with other species, auditory communication within a species, geographic locations, and inventions or innovations. Defining culture as the transmission of information by behavioral rather than genetical means, he demonstrates the continuum between the traits we find in animals and those we often consider uniquely human.
Shallow subterranean habitats (SSHs) are areas of habitable space that are less than 10 m in depth from the surface. These range from large areas such as shallow caves and lava tubes, to tiny areas such as cracks in ceilings, or spaces in soil. Whilst being very different in many ways, they are often bound together by shared characteristics of the habitats and their faunas, and their study can help us to understand subterranean habitats in general. This book concentrates on the more typical SSHs of intermediate size (seepage springs, spaces between rocks, cracks in lava etc.), describing the habitats, their fauna, and the ecological and evolutionary questions posed. Similarities and differences between the habitats are considered and discussed in a broader ecological and evolutionary context. The book is mainly aimed at students and researchers in the field of subterranean biology, but will also be of interest to a wider range of ecologists, evolutionary biologists, freshwater biologists, and conservationists. There will also be an audience of environmental professionals.
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.
For most of us the word "desert" conjures up images of barren wasteland, vast, dry stretches inimical to life. But for a great array of creatures, perhaps even more plentiful than those who inhabit tropical rainforests, the desert is a haven and a home. Travel with Michael Mares into the deserts of Argentina, Iran, Egypt, and the American Southwest and you will encounter a rich and memorable variety of these small, tenacious animals, many of them first discovered by Mares in areas never before studied. Accompanying Mares on his forays into these hostile habitats, we observe the remarkable behavioral, physiological, and ecological adaptations that have allowed such little-known species of rodents, bats, and other small mammals to persist in an arid world. At the same time, we see firsthand the perils and pitfalls that await biologists who venture into the field to investigate new habitats, discover new species, and add to our knowledge of the diversity of life. Filled with the seductions and trials that such adventures entail, "A Desert Calling" affords an intimate understanding of the biologist's vocation. As he astonishes us with the range and variety of knowledge to be acquired through the determined investigation of little-known habitats, Mares opens a window on his own uncommon life, as well as on the uncommon life of the remote and mysterious corners of our planet.
How do plants, animals, and humans manage to survive and adapt to the urban environment? This book provides a comprehensive coverage of biological matters related to urban environments presenting both the conceptual and theoretical underpinnings, and practical examples required to understand and address the challenges presented by this novel environment. The Biology of Urban Environments focusses on urban denizens: species (both domesticated and non-domesticated) that live for all or part of their life cycle in towns and cities. The biology of household plants and companion animals is discussed alongside that of species that have become feral or have not been domesticated. Temporal and spatial distribution patterns are set out and generalizations are made while exceptions are also discussed. The various strategies used and the genotypic, phenotypic, and behavioural adaptions of plants and animals in the face of the challenges presented by urban environments are explained. The final two chapters contain a discussion of the impacts of urban environments on human biology and suggestions on how this understanding might be used to address the increasing human health burden associated with illnesses that are characteristic of urbanites in the early twenty-first century.
This research level text documents the latest advances in odonate biology and relates these to a broader ecological and evolutionary research agenda. Despite being one of the smallest insect orders, dragonflies offer a number of advantages for both laboratory and field studies. In fact, they continue to make a crucial contribution to the advancement of our broader understanding of insect ecology and evolution. This new edition provides a critical summary of the major advances in these fields. The editors have carefully assembled a fresh set of contributions from a diverse geographic mix of both junior and senior researchers in dragonfly biology to offer new perspectives and paradigms as well as additional, unpublished data. These include theoretical and applied chapters (including those addressing conservation and monitoring) as well as a balance of emerging (e.g. molecular evolution) and established research topics, providing suggestions for future study in each case. This accessible text is not about dragonflies per se but is an essential source of knowledge that describes how different sets of evolutionary and ecological principles and ideas have been tested on a particular taxon. Dragonflies and Damselflies is suitable for graduate students and researchers in entomology, evolutionary biology, population and behavioural ecology, community ecology, and conservation biology. It will be of particular interest and use to those working on insects and an indispensable reference text for odonate biologists.
This is the first ever monumental and scientific documentation of the faunal wealth of the Indian Desert state of Rajasthan. This volume, the first of two, provides background on Rajasthan and covers species diversity and distribution of fauna. A scholarly contribution to the field of knowledge, it provides novel and vital information on the vertebrate faunal heritage of India's largest state. Broadly falling under the Indo-Malaya Ecozone, the three major biomes of Rajasthan include deserts and xeric shrublands, tropical and subtropical dry broadleaf forests, and tropical and subtropical moist broadleaf forests. The corresponding ecoregions to the above biomes are, respectively, the Thar Desert and northwestern thorn scrub forests, the Khathiar-Gir dry deciduous forests, and the Upper Gangtic Plains moist deciduous forests. Contrary to popular belief, the well-known Thar or Great Indian Desert occupies only a part of the state. Rajasthan is diagonally divided by the Aravalli mountain ranges into arid and semi-arid regions. The latter have a spectacular variety of highly diversified and unique yet fragile ecosystems comprising lush green fields, marshes, grasslands, rocky patches and hilly terrains, dense forests, the southern plateau, fresh water wetlands, and salt lakes. Apart from the floral richness, there is faunal abundance from fishes to mammals. In this volume, the various flagship and threatened species are described in the 24 chapters penned by top notch wildlife experts and academics. The world famous heronry, tiger reserves, wildlife sanctuaries and some threat-ridden biodiversity rich areas shall certainly draw the attention of readers from around the world.
Ethnozoology: Animals In Our Lives represents the first book about this discipline, providing a discussion on key themes on human-animal interactions and their implications, along with recent major advances in research. Humans share the world with a bewildering variety of other animals, and have interacted with them in different ways. This variety of interactions (both past and present) is investigated through ethnozoology, which is a hybrid discipline structured with elements from both the natural and social sciences, as it seeks to understand how humans have perceived and interacted with faunal resources throughout history. In a broader context, ethnozoology, and its companion discipline, ethnobotany, form part of the larger body of the science of ethnobiology. In recent years, the importance of ethnozoological/ethnobiological studies has increasingly been recognized, unsurprisingly given the strong human influence on biodiversity. From the perspective of ethnozoology, the book addresses all aspects of human connection, animals and health, from its use in traditional medicine, to bioprospecting derivatives of fauna for pharmaceuticals, with expert contributions from leading researchers in the field.
Thorp and Covich's Freshwater Invertebrates, Volume 5: Keys to Neotropical and Antarctic Fauna, Fourth Edition, covers inland water invertebrates of the world. It began with Ecology and General Biology, Volume One (Thorp and Rogers, editors, 2015) and was followed by three volumes emphasizing taxonomic keys to general invertebrates of the Nearctic (2016), neotropical hexapods (2018), and general invertebrates of the Palearctic (2019). All volumes are designed for multiple uses and levels of expertise by professionals in universities, government agencies, private companies, and graduate and undergraduate students.
Recent advances in the study of bats have changed the way we understand this illusive group of mammals. This volume consist of 25 chapters and 57 authors from around the globe all writing on the most recent finding on the evolution, ecology and conservation of bats. The chapters in this book are not intended to be exhaustive literature reviews, but instead extended manuscripts that bring new and fresh perspectives. Many chapters consist of previously unpublished data and are repetitive of new insights and understanding in bat evolution, ecology and conservation. All chapters were peer-reviewed and revised by the authors. Many of the chapters are multi-authored to provide comprehensive and authoritative coverage of the topics.
This book offers a concise but comprehensive introduction to desert ecology and adopts a strong evolutionary focus. As with other titles in the Biology of Habitats Series, the emphasis in the book is on the organisms that dominate this harsh environment, although theoretical and experimental aspects are also discussed. In this updated second edition, there is a greater focus on the effects of climate change and some of its likely effects on deserts, seeing desertification as among the most serious results of climate change, leading ultimately to the increasing size of arid and semi-arid regions. The Biology of Deserts Second Edition includes a wide range of ecological and evolutionary issues including morphological and physiological adaptations of desert plants and animals, species interactions, the importance of predation and parasitism, food webs, biodiversity, and conservation. It features a balance of plant and animal (both invertebrate and vertebrate) examples, and also emphasizes topical applied issues such as desertification and invasive species. The book concludes by considering the positive aspects of desert conservation. This accessible textbook is intended for senior undergraduate and graduate students, as well as professional ecologists, conservation practitioners, and resource managers working in the field of desert ecology.

The capybara is the neotropical mammal with the highest potential for production and domestication. Amongst the favorable characteristics for domestication we can list its high prolificacy, rapid growth rate, a herbivorous diet, social behavior and relative tameness. The genus (with only two species) is found from the Panama Canal to the north of Argentina on the east of the Andes. Chile is the only country in South America where the capybara is not found. The species is eaten all over its range, especially by poor, rural and traditional communities engaged in subsistence hunting. On the other hand, in large urban settlements wildlife is consumed by city dwellers as a delicacy. The sustainable management of capybara in the wild has been adopted by some South American countries, while others have encouraged capybara rearing in captivity. |
