Population dynamics and animal behaviour are two subjects which have developed almost independently, despite widespread acceptance of the idea that they must be related. This book provides a novel framework for combining these two subjects and then shows how to consider a range of conservation issues. It is aimed at students and researchers in animal behaviour, population ecology, and conservation biology.

Aldo Leopold: A Fierce Green Fire (OUP; 1999) remains the only biography for the general public on Leopold. It was praised for being concise and readable, and written in the context of the history of American conservation. In a second edition, Marybeth Lorbiecki has added new chapters on Leopold's legacy-the ripple effects of the ecological knowledge, ethics, and leadership he instilled in his wife's family in the Southwest, his children, graduate students, organizations-and on his relevance today. In a new introduction, Lorbiecki explains why Leopold is still so relevant, focusing on the new ecological challenges we face and the myriad of ways his work influences us today, including phenological studies he started at the Shack and their role in proving climate change, and responses to these challenges based on a land ethic. New chapters focus on the Leopold children and their contributions to the land ethic and ecology in their different scientific fields, Leopold's key graduate students and their contributions to various fields, and the recent activities of various organizations that Leopold helped launch.

Animals as geomorphic agents have primarily been considered "curiosities" in the literature of geomorphology, whose spatial and quantitative influences have been seen as both limited and minor. Zoogeomorphology: Animals as Geomorphic Agents examines the distinct geomorphic influences of invertebrates, ectothermic vertebrates, birds, and mammals, and demonstrates the importance of animals as landscape sculptors. Specific processes associated with the diversity of animal influences in geomorphology are examined, including burrowing and denning, nesting, lithophagy and geophagy, wallowing and trampling, food caching, excavating for food, and dam building by beavers. Particular emphasis is placed on terrestrial animals, although aquatic animals are also discussed where appropriate. This book, which is the only one available wholly devoted to this topic, will interest graduate students and professional research workers in geomorphology, ecology, environmental science, physical geography, and geology.

The "ant" and the "peacock" stand for two puzzles in Darwinism--altruism and sexual selection. How can natural selection favor those, such as the worker ant, that renounce tooth and claw in favor of the public-spirited ways of the commune? And how can "peacocks"--flamboyant, ornamental and apparently useless--be tolerated by the grimly economical Darwinian reaper? Helena Cronin has a deep understanding of today's answers to these riddles and their roots in the nineteenth century; the analysis is new and exciting and the explanations lucid and compelling.

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.

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.

Ziel des Buches ist es, herauszuarbeiten, in welchen Bereichen autistische Menschen mit psychischen Begleiterkrankungen persoenliche Therapiebedarfe sehen und wie diese aktuell in der Autismus- Therapie bearbeitet werden koennen. Dazu wird die Forschungsfrage "Wie grenzen erwachsene Menschen mit Autismus-Spektrum-Stoerung und psychiatrischer Komorbiditat ihre Therapieanliegen zwischen sogenannter Autismus-Therapie und Psychotherapie ab und wie sehr passt das zu Sichtweise, Moeglichkeiten und Kompetenzen der Autismus-Therapie?" gestellt. Anknupfend an einen theoriebasierten Teil mit Darstellung der haufigsten Komorbiditaten bei Autismus-Spektrum-Stoerungen sowie der aktuellen Rahmenbedingungen der Psychotherapie (Leistung der Krankenversicherung) und Autismustherapie (Leistung der Eingliederungshilfe) wurde zur Beantwortung der Frage eine qualitative Untersuchung durchgefuhrt. Die Ergebnisse der Interviews zeigen, dass eine Abgrenzung der Therapieanliegen zwischen Autismus-Therapie und Psychotherapie nur bedingt gelingt. Autismus-Therapieanbieter sind und sehen sich uberwiegend nicht in der Lage, spezifisch auf psychotherapeutische Fragestellungen einzugehen, auch wenn sich die autistischen Menschen im jeweiligen autismustherapeutischen Setting uberwiegend gut aufgehoben fuhlen.

A beautifully illustrated and thoroughly engaging cultural history of beekeeping - packed with anecdote, humour and enriching historical detail. The perfect gift. "A charming look at the history of beekeeping, from myth and folklore to our practical relationship with bees" Gardens Illustrated "An entertaining collation of bee trivia across the millennia" Daily Telegraph * Sweden's Gardening Book of the Year 2019 * Shortlisted for the August Prize 2019 * Winner of the Swedish Book Design Award for 2019 Beekeeper and garden historian Lotte Moeller explores the activities inside and outside the hive while charting the bees' natural order and habits. With a light touch she uses her encyclopaedic knowledge of the subject to shed light on humanity's understanding of bees and bee lore from antiquity to the present. A humorous debunking of the myths that have held for centuries is matched by a wry exploration of how and when they were replaced by fact. In her travels Moeller encounters a trigger-happy Californian beekeeper raging against both killer bees and bee politics, warring beekeepers on the Danish island of Laeso, and Brother Adam of Buckfast Abbey, breeder of the Buckfast queen now popular throughout Europe and beyond, as well a host of others as passionate as she about the complex world of apiculture both past and present.

This volume provides a modern introduction to the soil fauna and their contributions to ecosystem function, the mechanisms that structure soil fauna assemblages from local to global scales, and the potential impacts of global change on soil fauna assemblages and through this ecosystem function. Wanting to be an accessible primer, this book is a high level overview of current knowledge rather than a detailed tome of all existing information, with emphasis being placed on key findings and general patterns. It focuses on the soil fauna but contextualizes these assemblages in relation to the microbial assemblages belowground and the vegetation aboveground. It is clear that our knowledge of soil fauna assemblages is ever increasing, but there is still a lot to discover. Key areas of research are highlighted, with particular reference to the future of soil fauna assemblages.

Quaggas were beautiful pony-sized zebras in southern Africa that had fewer stripes on their bodies and legs, and a browner body coloration than other zebras. Indigenous people hunted quaggas, portrayed them in rock art, and told stories about them. Settlers used quaggas to pull wagons and to protect livestock against predators. Taken to Europe, they were admired, exhibited, harnessed to carriages, illustrated by famous artists and written about by scientists. Excessive hunting led to quaggas' extinction in the 1880s but DNA from museum specimens showed rebreeding was feasible and now zebras resembling quaggas live in their former habitats. This rebreeding is compared with other de-extinction and rewilding ventures and its appropriateness discussed against the backdrop of conservation challenges-including those facing other zebras. In an Anthropocene of species extinction, climate change and habitat loss which organisms and habitats should be saved, and should attempts be made to restore extinct species?

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.

"Murdoch, Briggs, and Nisbet provide the most insightful development of cohesive ecological theory to have appeared in decades. For those who would say ecology is not making progress, this is the book with which to refute such uninspired myopia. In this era of 'applied' and 'relevant ecology, ' a theory book might seem out of place. But we all need to read this book to remind ourselves how hard it is to really understand nature, and to appreciate the discipline of thinking required when deciphering the consequences of those environmental hazards from which we recoil."--Peter Kareiva, Lead Scientist, The Nature Conservancy

"This is a very important, well-written, and well-organized book. Its major contribution is in showing that real consumer-resource dynamics can in fact be understood using a unified theoretical framework. It will appeal to population ecologists but also to applied mathematicians, and will serve as an entree into theoretical ecology for those with less of a theoretical bent."--Alan Hastings, University of California, Davis

""Consumer-Resource Dynamics" is an important book that fills a significant void in the field of theoretical ecology. It brings together the seemingly disparate components of consumer-resource theory under a unifying framework, successfully tackles the challenge of developing models that are both general and testable, and makes complicated mathematical theory accessible to the more empirical minded ecologist. Unlike most books in the field, it presents new theory and new insights, and suggests new empirical directions to pursue. Very well written, it will find a wide audience, from theorists to empiricists, from students to professors, and frombasic scientists to applied researchers. It will provide food for thought even to those who are experts in the field."--Priyanga Amarasekare, University of Chicago

Does biodiversity influence how ecosystems function? Might diversity loss affect the ability of ecosystems to deliver services of benefit to humankind? Ecosystems provide food, fuel, fiber, and drinkable water, regulate local and regional climate, and recycle needed nutrients, among other things. An ecosyste's ability to sustain functioning may depend on the number of species residing in the ecosystem--its biological diversity--but this has been a controversial hypothesis. There are many unanswered questions about how and why changes in biodiversity could alter ecosystem functioning. This volume, written by top researchers, synthesizes empirical studies on the relationship between biodiversity and ecosystem functioning and extends that knowledge using a novel and coordinated set of models and theoretical approaches.

These experimental and theoretical analyses demonstrate that functioning usually increases with biodiversity, but also reveals when and under what circumstances other relationships between biodiversity and ecosystem functioning might occur. It also accounts for apparent changes in diversity-functioning relationships that emerge over time in disturbed ecosystems, thereby addressing a major controversy in the field. The volume concludes with a blueprint for moving beyond small-scale studies to regional ones--a move of enormous significance for policy and conservation but one that will entail tackling some of the most fundamental challenges in ecology.

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.

Bogland habitat, which is often threatened by peat extraction, has enormous natural history value. As well as the better-known plants, dragonflies and birds, it supports a unique community of microscopic animals and plants inhabiting the leaves and crevices of Sphagnum, the moss that dominates bog vegetation. Under the microscope, a single drop of water squeezed from bog moss reveals a wonderful diversity of complex and distinctive organisms. The peculiar characteristics of this bog moss habitat are described, and the book introduces the natural history and ecological interrelationships of its microscopic organisms, focusing in particular on the more obvious and elegant groups: the desmids, diatoms, shelled amoebae and rotifers or wheel animalcules. Identification is assisted by numerous detailed line illustrations and by the coloured plates. User-friendly keys will help the reader to allocate specimens to a group, and to name the more conspicuous genera of flagellates, desmids, diatoms, shelled amoebae and rotifers, as well as some species of Sphagnum itself. This is digital reprint of 0855462914 (1993).

Theoretical Ecology: concepts and applications continues the authoritative and established sequence of theoretical ecology books initiated by Robert M. May which helped pave the way for ecology to become a more robust theoretical science, encouraging the modern biologist to better understand the mathematics behind their theories. This latest instalment builds on the legacy of its predecessors with a completely new set of contributions. Rather than placing emphasis on the historical ideas in theoretical ecology, the Editors have encouraged each contribution to: synthesize historical theoretical ideas within modern frameworks that have emerged in the last 10-20 years (e.g. bridging population interactions to whole food webs); describe novel theory that has emerged in the last 20 years from historical empirical areas (e.g. macro-ecology); and finally to cover the rapidly expanding area of theoretical ecological applications (e.g. disease theory and global change theory). The result is a forward-looking synthesis that will help guide the field through a further decade of discovery and development. It is written for upper level undergraduate students, graduate students, and researchers seeking synthesis and the state of the art in growing areas of interest in theoretical ecology, genetics, evolutionary ecology, and mathematical biology.

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).

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

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.

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.

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.

Furry and wide-eyed, lorises and pottos are small, nocturnal primates inhabiting African, Asian and Southeast Asian tropical and subtropical forests. Their likeable appearance, combined with their unusual adaptations - from a marked reduction of the tail to their mostly slow, deliberate locomotion, powerful grasping and, in some species, a venomous bite - has led to a significant rise in research interest in the family Lorisidae over the last decade. Furthermore, lorises in particular have featured frequently in international media largely due to illegal trade, for example as pets. This is the first volume to present a full picture of the breadth of research being undertaken on lorisids to aid future studies as well as conservation efforts. Focusing on five key topics: evolutionary biology, ecomorphology, behavioural ecology, captive management and conservation, this book is a vital read for graduate students and researchers in primatology, biological anthropology, evolutionary biology, animal behaviour and conservation.
