Wytham Woods - Oxford's Ecological Laboratory (Paperback): Peter Savill, Christopher Perrins, Keith Kirby, Nigel Fisher Wytham Woods - Oxford's Ecological Laboratory (Paperback)
Peter Savill, Christopher Perrins, Keith Kirby, Nigel Fisher
R2,121 Discovery Miles 21 210 Ships in 12 - 19 working days

For the first time, this book tells the Wytham story in a way that is accessible to both scientist and general reader alike. It provides a fascinating overview of what the Woods are like, their history, composition (both plant and animal), and how their wildlife has changed over time.
This iconic location has been the subject of a series of continuous ecological research programs dating back to the 1920s, a level of continuity of research effort that is extremely rare. Hence there is a strong emphasis on the significance of the scientific research that has been done there and how this has contributed to ecological thinking elsewhere.

Plant-Animal Communication (Hardcover, New): H. Martin Schaefer, Graeme D. Ruxton Plant-Animal Communication (Hardcover, New)
H. Martin Schaefer, Graeme D. Ruxton
R4,124 Discovery Miles 41 240 Ships in 12 - 19 working days

Communication is an essential factor underpinning the interactions between species and the structure of their communities. Plant-animal interactions are particularly diverse due to the complex nature of their mutualistic and antagonistic relationships. However the evolution of communication and the underlying mechanisms responsible remain poorly understood.
Plant-Animal Communication is a timely summary of the latest research and ideas on the ecological and evolutionary foundations of communication between plants and animals, including discussions of fundamental concepts such as deception, reliability, and camouflage. It introduces how the sensory world of animals shapes the various modes of communication employed, laying out the basics of vision, scent, acoustic, and gustatory communication. Subsequent chapters discuss how plants communicate in these sensory modes to attract animals to facilitate seed dispersal, pollination, and carnivory, and how they communicate to defend themselves against herbivores. Potential avenues for productive theoretical and empirical research are clearly identified, and suggestions for novel empirical approaches to the study of communication in general are outlined.

Urbanization is a global phenomenon that is increasingly challenging human society. It is therefore crucially important to ensure that the relentless expansion of cities and towns proceeds sustainably. Urban ecology, the interdisciplinary study of ecological patterns and processes in towns and cities, is a rapidly developing field that can provide a scientific basis for the informed decision-making and planning needed to create both viable and sustainable cities.
Urban Ecology brings together an international team of leading scientists to discuss our current understanding of all aspects of urban environments, from the biology of the organisms that inhabit them to the diversity of ecosystem services and human social issues encountered within urban landscapes. The book is divided into five sections with the first describing the physical urban environment. Subsequent sections examine ecological patterns and processes within the urban setting, followed by the integration of ecology with social issues. The book concludes with a discussion of the applications of urban ecology to land-use planning. The emphasis throughout is on what we actually know (as well as what we should know) about the complexities of social-ecological systems in urban areas, in order to develop urban ecology as a rigorous scientific discipline.

Animal Migration - A Synthesis (Hardcover, New): E.J.Milner- Gulland, John M. Fryxell, Anthony R. E. Sinclair Animal Migration - A Synthesis (Hardcover, New)
E.J.Milner- Gulland, John M. Fryxell, Anthony R. E. Sinclair
R5,117 Discovery Miles 51 170 Ships in 12 - 19 working days

Despite the wealth of natural historical research conducted on migration over decades, there is still a dearth of hypothesis-driven studies that fully integrate theory and empirical analyses to understand the causes and consequences of migration, and a taxonomic bias towards birds in much migration research. This book takes a comparative, integrated view of animal migration, linking evolution with ecology and management, theory with empirical research, and embracing all the major migratory taxa (including human pastoralists). The scope extends beyond the target organism to consider the ecosystem-level dynamics of migration. The emphasis is on exciting new research avenues that are now opening up, whether due to advances in our understanding of migration as a biological phenomenon or through the availability of a range of new technologies.
Broad themes that emerge include integrating migration into the broad spectrum of movement behavior, the need for a comparative and cross-taxonomic approach that considers migration at a range of temporal and spatial scales, and examination of the key roles of resource uncertainty and spatial heterogeneity in driving migratory behavior. The book identifies the potential for new tools to revolutionize the study of migration, including satellite-tracking technology, genomics, and modeling - all of which are linked to increasing computing power. We are now on the verge of a breakthrough in migration research, which is crucial given the multiple threats that face the conservation of migration as a phenomenon, including climate change.

Principles of Social Evolution (Hardcover): Andrew F.G. Bourke Principles of Social Evolution (Hardcover)
Andrew F.G. Bourke
R4,935 Discovery Miles 49 350 Ships in 12 - 19 working days

Living things are organized in a hierarchy of levels. Genes group together in cells, cells group together in organisms, and organisms group together in societies. Even different species form mutualistic partnerships. Throughout the history of life, previously independent units have formed groups that, in time, have come to resemble individuals in their own right. Evolutionary biologists term such events "the major transitions." The process common to them all is social evolution. Each transition occurs only if natural selection favors one unit joining with another in a new kind of group.
This book presents a fresh synthesis of the principles of social evolution that underlie the major transitions, explaining how the basic theory underpinning social evolution - inclusive fitness theory - is central to understanding each event. The book defines the key stages in a major transition, then highlights the shared principles operating at each stage across the transitions as a whole. It addresses in new ways the question of how, once they have arisen, organisms and societies become more individualistic.

Introducing Biological Energetics - How Energy and Information Control the Living World (Hardcover, New): Norman W.H. Cheetham Introducing Biological Energetics - How Energy and Information Control the Living World (Hardcover, New)
Norman W.H. Cheetham
R4,607 Discovery Miles 46 070 Ships in 12 - 19 working days

Introducing Biological Energetics is a novel, interdisciplinary text that presents biological understanding in terms of general underlying principles, treating energy as the overarching theme and emphasizing the all-pervading influence of energy transformation in every process, both living and non-living. Key processes and concepts are explained in turn, culminating in a description of the overall functioning and regulation of a living cell. The book rounds off the story of life with a brief account of the endosymbiotic origins of eukaryotic cells, the development of multicellularity, and the emergence of modern plants and animals.
Multidisciplinary research in science is becoming commonplace. However, as traditional boundaries start to break down, researchers are increasingly aware of the deficiencies in their knowledge of related disciplines. Introducing Biological Energetics redresses the reciprocal imbalance in the knowledge levels of physical and biological scientists in particular. Its style of presentation and depth of treatment has been carefully designed to unite these two readerships.

Origins of Biodiversity - An Introduction to Macroevolution and Macroecology (Paperback): Lindell Bromham, Marcel Cardillo Origins of Biodiversity - An Introduction to Macroevolution and Macroecology (Paperback)
Lindell Bromham, Marcel Cardillo
R1,384 Discovery Miles 13 840 Ships in 9 - 17 working days

Origins of Biodiversity is a unique introduction to the fields of macroevolution and macroecology, which explores the evolution and distribution of biodiversity across time, space and lineages. Using an enquiry-led framework to encourage active learning and critical thinking, each chapter is based around a case-study to explore concepts and research methods from contemporary macroevolution and macroecology. The book focuses on the process of science as much as the biology itself, to help students acquire the research skills and intellectual tools they need to understand and investigate the biological world around them. In particular, the emphasis on hypothesis testing encourages students to develop and test their own ideas. This text builds upon the foundations offered in most general introductory evolutionary biology courses to introduce an exciting range of ideas and research tools for investigating patterns of biodiversity.

The Evolution of Primary Sexual Characters in Animals (Hardcover): Janet Leonard, Alex Cordoba-Aguilar The Evolution of Primary Sexual Characters in Animals (Hardcover)
Janet Leonard, Alex Cordoba-Aguilar
R3,469 Discovery Miles 34 690 Ships in 12 - 19 working days

Primary sexual traits, those structures and processes directly involved in reproduction, are some of the most diverse, specialized, and bizarre in the animal kingdom. Moreover, reproductive traits are often species-specific, suggesting that they evolved very rapidly. This diversity, long the province of taxonomists, has recently attracted broader interest from evolutionary biologists, especially those interested in sexual selection and the evolution of reproductive strategies.
Primary sexual characters were long assumed to be the product of natural selection, exclusively. A recent alternative suggests that sexual selection explains much of the diversity of "primary" sexual characters. A third approach to the evolution of reproductive interactions after copulation or insemination has been to consider the process one of sexual conflict. That is, the reproductive processes of a species may reflect, as does the mating system, evolution acting on males and on females, but in different directions.
In this volume, authors explore a wide variety of primary sexual characters and selective pressures that have shaped them, from natural selection for offspring survival to species-isolating mechanisms, sperm competition, cryptic female choice and sexual arms races. Exploring diverse reproductive adaptations from a theoretical and practical perspective, The Evolution of Primary Sexual Characters will provide an unparalleled overview of sexual diversity in many taxa and an introduction to the issues in sexual selection that are changing our view of sexual processes.

Can horses feel shame? Do deer grieve? Why do roosters deceive hens? We tend to assume that we are the only living things able to experience feelings but have you ever wondered what's going on in an animal's head? From the leafy forest floor to the inside of a bee hive, The Inner Life of Animals opens up the animal kingdom like never before. We hear the stories of a grateful humpback whale, of a hedgehog who has nightmares, and of a magpie who commits adultery; we meet bees that plan for the future, pigs who learn their own names and crows that go tobogganing for fun. And at last we find out why wasps exist.

Food Sharing in Human Societies - Anthropological Perspectives (Paperback, 1st ed. 2021): Nobuhiro Kishigami Food Sharing in Human Societies - Anthropological Perspectives (Paperback, 1st ed. 2021)
Nobuhiro Kishigami
R3,085 Discovery Miles 30 850 Ships in 10 - 15 working days

This book explores why human beings share food with others using a humanistic anthropological approach. This book provides a comparative examination of distinct features and historical changes in food-sharing practices in various hunting-gathering societies, especially in the Inuit. The author considers human nature through various human food-sharing practices. Food sharing is a characteristic of human behavior and has been one of the central topics in anthropological studies of hunter-gatherers for a long time. While anthropologists have attempted to understand it in functional, historical, adaptational, social, cultural, psychological, or phenomenological perspective, they have failed to convincingly explain its origin, variation, existence or/and change. Recently, evolutionary ecology or behavioral ecology has dominated research of the topic. However, neither of them adequately considers social, cultural and historical factors in the analysis of human food-sharing practices. This book is an essential and fundamental study for every researcher interested in the relationship between human nature, society and culture.

Bioinvasions and Globalization - Ecology, Economics, Management, and Policy (Hardcover): Charles Perrings, Harold Mooney, Mark... Bioinvasions and Globalization - Ecology, Economics, Management, and Policy (Hardcover)
Charles Perrings, Harold Mooney, Mark Williamson
R2,274 Discovery Miles 22 740 Ships in 12 - 19 working days

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 - Processes, Models, and Applications (Hardcover, New): Herman A. Verhoef, Peter J. Morin Community Ecology - Processes, Models, and Applications (Hardcover, New)
Herman A. Verhoef, Peter J. Morin
R4,171 Discovery Miles 41 710 Ships in 12 - 19 working days

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.

R5,063 R4,270 Discovery Miles 42 700 Save R793 (16%) Ships in 12 - 19 working days

Bumblebees are familiar and charismatic insects, occurring throughout much of the world. They are increasingly being used as a model organism for studying a wide range of ecological and behavioural concepts, such as social organization, optimal foraging theories, host-parasite interactions, and pollination. Recently they have become a focus for conservationists due to mounting evidence of range contractions and catastrophic extinctions with some species disappearing from entire continents (e.g. in North America). Only by improving our understanding of their ecology can we devise sensible plans to conserve them. The role of bumblebees as invasive species (e.g. Bombus terrestris in Japan) has also become topical with the growing trade in commercial bumblebee nests for tomato pollination leading to establishment of non-native bumblebees in a number of countries.
Since the publication of the first edition of the book, there have been hundreds of research papers published on bumblebees. There is clearly a continuing need for an affordable, well-illustrated, and appealing text that makes accessible all of the major advances in understanding of the behaviour and ecology of bumblebees that have been made in the last 30 years.

Invasion Biology (Paperback): Mark A. Davis Invasion Biology (Paperback)
Mark A. Davis
R2,520 Discovery Miles 25 200 Ships in 12 - 19 working days

With the exception of climate change, biological invasions have probably received more attention during the past ten years than any other ecological topic. Yet this is the first synthetic, single-authored overview of the field since Williamson's 1996 book. Written fifty years after the publication of Elton's pioneering monograph on the subject, Invasion Biology provides a comprehensive and up-to-date review of the science of biological invasions while also offering new insights and perspectives relating to the processes of introduction, establishment, and spread. The book connects science with application by describing the health, economic, and ecological impacts of invasive species as well as the variety of management strategies developed to mitigate harmful impacts. The author critically evaluates the approaches, findings, and controversies that have characterized invasion biology in recent years, and suggests a variety of future research directions. Carefully balanced to avoid distinct taxonomic, ecosystem, and geographic (both investigator and species) biases, the book addresses a wide range of invasive species (including protists, invertebrates, vertebrates, fungi, and plants) which have been studied in marine, freshwater, and terrestrial environments throughout the world by investigators equally diverse in their origins.
This accessible and thought-provoking text will be of particular interest to graduate level students and established researchers in the fields of invasion biology, community ecology, conservation biology, and restoration ecology. It will also be of value and use to land managers, policy makers, and other professionals charged with controlling the negative impacts associated with recently arrived species.

Animal Osmoregulation (Paperback, New): Timothy J Bradley Animal Osmoregulation (Paperback, New)
Timothy J Bradley
R2,064 Discovery Miles 20 640 Ships in 12 - 19 working days

Water is fundamental to life and all metabolic reactions are influenced by the aqueous environment in which they occur. Osmoregulation and water balance are therefore absolutely essential topics in animal physiology.
Animal Osmoregulation collates a widely dispersed literature to produce a comprehensive and authoritative synthesis of the field, providing detailed examples of osmoregulatory processes at the organismal, organ and cellular level. It incorporates clear background information on ion regulation and transport (specifically in the light of recent molecular studies) and illustrates the physical principles to which each organism must adhere, as well as the phylogenetic constraints within which it must operate.
As with other titles in the Oxford Animal Biology Series, the topic is addressed using examples from throughout the animal kingdom, identifying common themes that transcend taxonomy.

Fevered Planet - How Diseases Emerge When We Harm Nature (Hardcover, Unabridged edition): John Vidal Fevered Planet - How Diseases Emerge When We Harm Nature (Hardcover, Unabridged edition)
John Vidal
R568 Discovery Miles 5 680 Ships in 12 - 19 working days

Covid-19, monkeypox, bird flu, SARS, HIV, AIDS, Ebola; we are living in the Age of Pandemics – one that we have created. As the climate crisis reaches a fever pitch and ecological destruction continues unabated, we are just beginning to reckon with the effects of environmental collapse on our global health. Fevered Planet exposes how the way we farm, what we eat, the places we travel to and the scientific experiments we conduct create the perfect conditions for deadly new diseases to emerge and spread faster and further than ever. Drawing on the latest scientific research and decades of reporting from more than 100 countries, former Guardian environment editor John Vidal takes us into deep, disappearing forests in Gabon and the Congo, valleys scorched by wildfire near Lake Tahoe and our densest, polluted cities to show how closely human, animal and plant diseases are now intertwined with planetary destruction. From fossil fuel use raising the global temperature to increased logging polluting our landscapes, Fevered Planet exposes the perils of reckless environmental destruction – not just to our planet but to ourselves. As Vidal expertly argues, unless we transform our relationship with the rest of the natural world, the pandemics we are facing today will just be the tip of the iceberg.

Evolutionary Ecology of Social and Sexual Systems - Crustaceans as Model Organisms (Hardcover): J. Emmett Duffy, Martin Thiel Evolutionary Ecology of Social and Sexual Systems - Crustaceans as Model Organisms (Hardcover)
J. Emmett Duffy, Martin Thiel
R2,157 Discovery Miles 21 570 Ships in 12 - 19 working days

Understanding of animal social and sexual evolution has seen a renaissance in recent years with discoveries of frequent infidelity in apparently monogamous species, the importance of sperm competition, active female mate choice, and eusocial behavior in animals outside the traditional social insect groups. Each of these findings has raised new questions, and suggested new answers, about the evolution of behavioral interactions among animals. This volume synthesizes recent research on the sexual and social biology of the Crustacea, one of the dominant invertebrate groups on earth. Its staggering diversity includes ecologically important inhabitants of nearly every environment from deep-sea trenches, through headwater streams, to desert soils. The wide range of crustacean phenotypes and environments is accompanied by a comparable diversity of behavioral and social systems, including the elaborate courtship and wildly exaggerated morphologies of fiddler crabs, the mysterious queuing behavior of migrating spiny lobsters, and even eusociality in coral-reef shrimps. This diversity makes crustaceans particularly valuable for exploring the comparative evolution of sexual and social systems. Despite exciting recent advances, however, general recognition of the value of Crustacea as models has lagged behind that of the better studied insects and vertebrates. This book synthesizes the state of the field in crustacean behavior and sociobiology and places it in a conceptually based, comparative framework that will be valuable to active researchers and students in animal behavior, ecology, and evolutionary biology. It brings together a group of internationally recognized and rising experts in fields related to crustacean behavioral ecology, ranging from physiology and functional morphology, through mating and social behavior, to ecology and phylogeny. Each chapter makes connections to other, non-crustacean taxa, and the volume closes with a summary section that synthesizes the contributions, discusses anthropogenic impacts, highlights unanswered questions, and provides a vision for profitable future research.

The Man Who Saved Sea Turtles - Archie Carr and the Origins of Conservation Biology (Hardcover): Frederick R. Davis The Man Who Saved Sea Turtles - Archie Carr and the Origins of Conservation Biology (Hardcover)
Frederick R. Davis
R1,508 Discovery Miles 15 080 Ships in 12 - 19 working days

Archie Carr, one of the greatest biologists of the twentieth century, played a leading part in finding a new and critical role for natural history and systematics in a post-1950s world dominated by the glamorous science of molecular biology. With the rise of molecular biology came a growing popular awareness of species extinction. Carr championed endangered sea turtles, and his work reflects major shifts in the study of ecology and evolution. A gifted nature writer, his books on the natural history of sea turtles and their habitats in Florida, the Caribbean, and Africa entertained and educated a wide audience. Carr's conservation ethic grew from his field work as well as his friendships with the fishermen who supplied him with many of the stories he retold so engagingly. With Archie Carr as the focus, The Man Who Saved Sea Turtles explores the evolution of the naturalist tradition, biology, and conservation during the twentieth century.

Ivorybill Hunters - Search for Proof in a Flooded Wilderness (Hardcover): Geoffrey E. Hill Ivorybill Hunters - Search for Proof in a Flooded Wilderness (Hardcover)
Geoffrey E. Hill
R1,186 Discovery Miles 11 860 Ships in 12 - 19 working days

The last documented sighting of the Ivory-billed Woodpecker--one of the rarest and most intriguing animals in the world--was noted over 50 years ago. Long thought to be extinct, the 2005 announcement of a sighting in Arkansas sparked tremendous enthusiasm and hope that this species could yet be saved. But the subsequent failure of a massive search to relocate Ivorybills in Arkansas made hope for the species' revival short-lived.
Here, noted ornithologist Geoffrey Hill tells the story of how he and two of his colleagues stumbled upon what may be a breeding population of Ivory-billed Woodpeckers in the swamps of northern Florida. He relates their laborious attempts to document irrefutable evidence for the existence of this shy, elusive bird following the failure of a much larger research team to definitively prove the bird's existence.
Hill tells of his travails both in and out of the vast swamp wilderness, pulling back the curtain to reveal the little-seen political maneuvering that is part of all modern science. He explains how he and his group decided who to exclude or include as their findings came in, and why they felt the need to keep their search a secret. Hill returns repeatedly to how expectations can guide observations, and how tempting it is to oversell evidence in the face of the struggle between an overwhelming desire to find the bird and the need to retain integrity and objectivity.
Written like a good detective story, Ivorybill Hunters also delves into the science behind the rediscovery of a species, explaining how professional ornithologists follow up on a sight record of a rare bird, and how this differs from the public's perception of how scientistsactually work. Hill notes the growing role of amateurs in documenting bird activity and discusses how the community of birders and nature lovers can see, enjoy, and help preserve these birds.
Ivorybill Hunters will prove a fascinating read for those with an interest in natural history, adventure, environmental conservation, and science, as well as the more than forty-six million Americans who now call themselves birdwatchers.
