The manufacture of plastic as well as its indiscriminate disposal and destruction by incineration pollutes atmospheric, terrestrial, and aquatic ecosystems. Synthetic plastics do not break down; they accumulate in the environment as macro-, micro-, and nanoplastics. These particulate plastics are a major source of pollutants in soil and marine ecosystems. Particulate Plastics in Terrestrial and Aquatic Environments provides a fundamental understanding of the sources of these plastics and the threats they pose to the environment. The book demonstrates the ecotoxicity of particulate plastics using case studies and offers management practices to mitigate particulate plastic contamination in the environment. Features * Describes physical and chemical properties of particulate plastics in terrestrial and aquatic ecosystems * Presents information on characteristics of particulate plastics as impacted by weathering processes * Provides numerous approaches for managing particulate plastic contamination * Identifies sources of particulate plastics in the environment; distribution and characteristics of particulate plastics; and management strategies of particulate plastics Written by a global team of scientists, this book is for researchers in the fields of environmental safety and waste management or individuals interested in the impact of particulate plastics on environmental health.

Managing the Return of the Wild - Human Encounters with Wolves in Europe (Hardcover): Michaela Fenske, Bernhard Tschofen Managing the Return of the Wild - Human Encounters with Wolves in Europe (Hardcover)
Michaela Fenske, Bernhard Tschofen
R3,878 Discovery Miles 38 780 Ships in 12 - 17 working days

This book explores attitudes and strategies towards the return of the wild in times of ecological crisis, focusing on wolves in Europe. The contributions from a variety of disciplines discuss human encounters with wolves, engaging with traditional narratives and contemporary conflicts. Covering a range of geographical areas, the case studies featured demonstrate the tremendous impact of the return of the wolf in European societies. Wolves are a keystone species that exemplify humanity's relation to what is called nature and their return generates powerful debates about what 'nature' actually is and how much it is needed or should be permitted to exist. The book considers the return of the wild as a catalyst for fundamental socio-biological changes of the world within human societies, and the various responses of humans to wolves demonstrate both our potential and limitations when it comes to multispecies communities and negotiating societal change. Managing the Return of the Wild will be relevant to a broad audience interested in discussions of social and ecological conflict today, including scholars from multispecies studies and diverse disciplines such as biology, forestry management and folklore studies.

Handbook of Ethological Methods (Hardcover, 2nd Revised edition): Philip N. Lehner Handbook of Ethological Methods (Hardcover, 2nd Revised edition)
Philip N. Lehner
R2,572 Discovery Miles 25 720 Ships in 12 - 17 working days

At first glance, studying behavior is easy, but as every budding ethologist quickly realizes, there are a host of complex practical, methodological and analytical problems to solve before designing and conducting the study. How do you choose which species or which behavior to study? What equipment will you need to observe and record behavior successfully? How do you record data in the dark, in the wet, or without missing part of the action? How do you analyze and interpret the data to yield meaningful information? This new expanded edition of the Handbook of Ethological Methods provides a complete step-by-step introduction to ethological methods from topic choice and behavioral description to data collection and statistical analysis. This book is a must for both beginning students and experienced researchers studying animal behavior in the field or laboratory.

Climate Change and Animal Health (Paperback): Craig Stephen, Colleen Duncan Climate Change and Animal Health (Paperback)
Craig Stephen, Colleen Duncan
R1,424 Discovery Miles 14 240 Ships in 12 - 17 working days

DIRECTLY APPLIES TO LIFE ON LAND SDG and CLIMATE CHANGE SDG. International organizations such as the Intergovernmental Panel on Climate Change (IPPC), World Health Organization, Food and Agriculture Organization and World Organization for Animal Health have all reminded us that health impacts of climate change will become some of societies' greatest challenges. How we respond or adapt to climate change will have profound implications for people, animals, biodiversity, economies and ecosystems today as well as in the future. The book provides, in one easy reference, all of the information Animal Health practitioners need from defining the climate change concept, providing science-based evidence of climate change degradation of animal (ecosystem) health and successful mitigation and reversal strategies. Despite being arguably the most important challenges of the 21st century, engagement, and leadership from the animal health sector on climate change remains hard to find. This book attempts to support animal health professionals by providing information, knowledge, and experiences they can use to remedy this situation. There is no other book that covers anything like the proposed subject matter to this level of completeness and detail. The publishing of a text of this nature could help erode the power of the climate denialism lobby, shifting the debate and allowing mitigation efforts to gain higher priority. The tone of the book has an understated sense of urgency, leaning slightly toward presenting as a 'Manual for the apocalypse'. This has potential to be a benchmark publication. The text not only defines climate change but takes a proactive approach with intervention and corrective action examples: each chapter ends with suggestions on teachable and actionable ideas that could be used to mobilize concepts and information provided into education or advocacy. In this way, the book not only brings key ideas, principles and information to understand the implications for climate change for animal health, but will help translate the book's offerings into education and intervention. Teachers and researchers could use this one-of-a-kind book to frame a course or seminar series heightening student career engagement and stewardship of a more sustainable and healthier planet.

John Gunn, Robert John Steedman, Richard Ryder
R1,873 Discovery Miles 18 730 Ships in 12 - 17 working days

Boreal Shield Watersheds: Lake Trout Ecosystems in a Changing Environment brings together the work of a renowned international group of scientists who specialize in aquatic science and environmental management. They explore the functioning of Boreal Shield ecosystems, focusing on the lake trout, the classic coldwater species of northern glaciated lakes, using it as an indicator of environmental change and as a model to measure the effectiveness of management actions. This book demonstrates how boreal waters have served as a crucible for decades of environmental research into the impacts of nutrient additions, trace contaminants, acid rain, climate change, sport fishing, invasive species, and watershed disturbances. The text builds on this substantial research legacy and explores our ability to manage human interactions with ecosystems across the vast Boreal Shield ecozone of North America, and with other important ecosystems worldwide. It also provides models and new methods of assessing the risk to and the durability of ecosystems in relation to local, regional, and global human activities. Maps and descriptions of several important long-term monitoring sites and an atlas describing more than 3,000 lake trout lakes in the region are special components of the book.

R2,788 Discovery Miles 27 880 Ships in 12 - 17 working days

Speech, verbally mediated consciousness, and culture most evidently differentiate people from animals. Moreover, verbal communication has historically been viewed as a human attribute. Yet, the biological precursors to verbal communication exist in animal communication: obvious links have been found between human and animal nonverbal vocal communication. Knowledge of these links contribute to our understanding of three major theoretical and clinical issues: the evolution of vocal communication; the process of speech acquisition during infancy; and the pathways of disorders in communicative development. In Nonverbal Vocal Communication specialists from several disciplines review the present knowledge on neural substrates of vocal communication, on primate vocal communication, and on precursors and prerequisites of human speech. Among other points, the book illustrates that animal vocal signals, particularly in primates, appear to be much more complex than mere expressions of effective states. The nonverbal communication data is complemented by comparative and developmental research of the preverbal period of human vocal communication. Studies of speech acquisition, biological adaptation and environmental support to speech yield a complex picture of interrelations between biogenetic and environmental factors. The new evidence that parents--without knowing--are well-fitted for supporting infant communicative development is astonishing. Their capacities represent a primary, biological model of didactic educational support.

Wildlife Science - Linking Ecological Theory and Management Applications (Paperback): Timothy E Fulbright, David G. Hewitt Wildlife Science - Linking Ecological Theory and Management Applications (Paperback)
Timothy E Fulbright, David G. Hewitt
R1,851 Discovery Miles 18 510 Ships in 12 - 17 working days

Consciously or not, wildlife managers generally act from a theoretical basis, although they may not be fully versed in the details or ramifications of that theory. In practice, the predictions of the practitioners sometimes prove more accurate than those of the theoreticians. Practitioners and theoreticians need to work together, but this proves difficult when new management ideas and cutting-edge ecological theory are often published in separate scientific outlets with distinctly different readerships. A compilation of the scientific papers presented at the Caesar Kleberg Wildlife Research Institute's 25th Anniversary Conference of April 2006, Wildlife Science: Linking Ecological Theory and Management Applications brings together these two often separate approaches to elucidate the theoretical underpinnings of wildlife management and to apply evolving ecological concepts to changes and adaptations in management practices. Gathering many of the best and greatest minds in wildlife science, this volume addresses the critically important theme of linking ecological theory and management applications. Divided into five parts, the first two parts deal with the landscape ecology of birds and mammals respectively, demonstrating the need for applied theory in gamebird management and the preservation of the cougar. Part three highlights the role of climate when applying ecological theory to habitat management and discusses the emergence of ecosystem management in managing wildlife at the ecosystem scale. Part four considers the management of wildlife disease and reveals the increasing importance of genetics in conservation and ecology. Finally, the economic and social issues affecting wildlife science round out the coverage in part five. Applying emerging ecological theory for the advancement of wildlife management, Wildlife Science: Linking Ecological Theory and Management Applications provides a long awaited cooperative look at the future of ecosystem manage

R1,284 Discovery Miles 12 840 Ships in 12 - 17 working days

Southeast Asia is highly diversified in terms of socio-ecosystems and biodiversity, but is undergoing dramatic environmental and social changes. These changes characterize the recent period and can be illustrated by the effects of the Green Revolution in the late 1960s and 1970s, to the globalization of trade and increasing agronomic intensification over the past decade. Biodiversity Conservation in Southeast Asia provides theoretical overviews and challenges for applied research in living resource management, conservation ecology, health ecology and conservation planning in Southeast Asia. Five key themes are addressed: origin and evolution of Southeast Asian biodiversity; challenges in conservation biology; ecosystem services and biodiversity; managing biodiversity and living resources; policy, economics and governance of biodiversity. Detailed case studies are included from Thailand and the Lower Mekong Basin, while other chapters address cross-cutting themes applicable to the whole Southeast Asia region. This is a valuable resource for academics and students in the areas of ecology, conservation, environmental policy and management, Southeast Asian studies and sustainable development.

The frontier images of America embrace endless horizons, majestic herds of native ungulates, and romanticized life-styles of nomadie peoples. The images were mere reflections of vertebrates living in harmony in an ecosystem driven by the unpre dictable local and regional effects of drought, frre, and grazing. Those effects, often referred to as ecological "disturbanees," are rather the driving forces on which species depended to create the spatial and temporal heterogeneity that favored ecological prerequisites for survival. Alandscape viewed by European descendants as monotony interrupted only by extremes in weather and commonly referred to as the "Great American Desert," this country was to be rushed through and cursed, a barrier that hindered access to the deep soils of the Oregon country, the rich minerals of California and Colorado, and the religious freedom sought in Utah. Those who stayed (for lack of resources or stamina) spent a century trying to moderate the ecological dynamics of Great Plains prairies by suppressing fires, planting trees and exotic grasses, poisoning rodents, diverting waters, and homogenizing the dynamies of grazing with endless fences-all creating bound an otherwise boundless vista. aries in Historically, travelers and settlers referred to the area of tallgrasses along the western edge of the deciduous forest and extending midway across Kansas as the "True Prairie. " The grasses thlnned and became shorter to the west, an area known then as the Great Plains."

R2,793 Discovery Miles 27 930 Ships in 12 - 17 working days

Islands with large colonies of seabirds are found throughout the globe. Seabird islands provide nesting and roosting sites for birds that forage at sea, deposit marine nutrients on land, and physically alter these islands. Habitats for numerous endemic and endangered animal and plant species, seabird islands are therefore biodiversity hotspots with high priority for conservation.
Successful campaigns to eradicate predators (e.g., rats and cats) from seabird islands have been conducted worldwide. However, removal of predators will not necessarily lead to natural recovery of seabirds or other native species. Restoration of island ecosystems requires social acceptance of eradications, knowledge of how island food webs function, and a long-term commitment to measuring and assisting the recovery process.
This book, written collaboratively by and for ecologists and resource managers, provides the first large-scale cross-system compilation, comparison, and synthesis of the ecology of seabird island systems. Offering a new conceptual framework into which to fit the impacts of seabirds on island ecology, this is an essential resource for academics and resource managers alike.

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?

R2,583 Discovery Miles 25 830 Ships in 12 - 17 working days

This volume charts a new course in animal studies that re-examines Jacques Derrida's enduring thought on the visualization of the animal in his seminal Cerisy Conference from 1997, The Animal That Therefore I Am. Building new proximities with the animal in and through - and at times in spite of - the visual apparatus, Seeing Animals after Derrida investigates how the recent turn in animal studies toward new materialism, speculative realism, and object-oriented ontology prompts a renewed engagement with Derrida's animal philosophy. In taking up the matter of Derrida's treatment of animality for the current epoch, the contributors to this book each present a case for new philosophical approaches and aesthetic paradigms that challenge the ocularcentrism of Western culture.

When Nancy Beckage and I first met in Lynn Riddiford's laboratory at the University of Washington in the mid 1970s, the fields of parasitology, behavior, and endocrinology were thriving and far-flung--disciplines in no serious danger of intersecting. There were rumors that they might have some common ground: Behavioural Aspects of Parasite Transmission (Canning and Wright, 1972) had just emerged, with exciting news not only of the way parasites themselves behave, but also of Machiavellian worms that caused intermediate hosts to shift fundamental responses to light and disturbance, becoming in the process more vulnerable to predation by the next host (Holmes and Bethel, 1972). Meanwhile, biologists such as Miriam Rothschild (see Dedication), G. B. Solomon (1969), and Lynn Riddiford herself (1975) had suggested that the endocrinological rami of parasitism might be subtle and pervasive. In general, however, para fications sites were viewed as aberrant organisms, perhaps good for a few just-so stories prior to turning our attention once again to real animals. In the decade that followed, Pauline Lawrence (1986a, b), Davy Jones (Jones et al., 1986), Nancy Beckage (Beckage, 1985; Beckage and Templeton, 1986), and others, including many in this volume, left no doubt that the host-parasite combination in insect systems was physiologically distinct from its unparasitized counterpart in ways that went beyond gross pathology."

R1,399 Discovery Miles 13 990 Ships in 12 - 17 working days

The key aim of this book is to explore the global conservation and management of sharks. There has been a rapid decline in populations of many shark species, while new science has emerged of the critical role they play in marine ecosystems. However, the authors show that conservation law and policy have been slow to develop, with only a small number of iconic species being protected worldwide. The increase in fishing impact - primarily through shark finning and by-catch - has led to shark conservation receiving greater international attention in recent years. The book explores our current knowledge and status of the law and science in relation to sharks with a particular focus on improving frameworks for their conservation and management. Recent trends are analysed, including shark finning bans that have been put in place in several countries, the widening number of nations establishing shark sanctuaries and the growth of shark-based tourism. The efficacy of current listing processes for endangered species and fisheries regulations is also examined. Tourism is explored as an alternative to fishing and the risks and impacts associated with this industry are analysed. Contributors include leading authorities from universities and conservation organizations in North America, Europe and Australia. A common theme is to emphasise the importance of collaborative governance between various interest groups and the need for inter-disciplinary research and management approaches that are necessary to address the decline in sharks.

__________________ Our Earth is more beautiful and more diverse than we can possibly conceive of. The Book of Vanishing Species is a stunning homage to the planet's most mysterious, bizarre and wondrous creatures and plants. Their stories are captivating, from the eyeless and tiny dragonlike olm to the hawksbill turtle, whose gender will be determined by the temperature of the sand it is born in. These species may have survived for hundreds of thousands of years by cleverly adapting to their environments, but their future remains far from certain. The book brings to life red cranes as they dance and bow for the sheer joy of movement, trees that breathe out a haze of misty atmosphere for insects that only feast on one kind of flower, a deep-ocean snail quietly building its shell from iron... and each one of them is illuminated with an exquisite illustration. As you turn the pages, there emerges a network of life that stretches across and around the planet in a dazzling web of existence. This is both a love letter to life on Earth, and an urgent summons to protect what is precious and lovely in this world.

Scarcity of water has brought about a number of structural, behavioural, physiological and ecological adaptations in amphibians inhabiting seasonally xeric habitats.
This book describes structural and functional adaptations of key organs such as skin, kidneys, bladder, lungs and ovaries. Behavioural responses to high temperatures mainly involve thermoregulation and the selection of optimal temperatures and humidity. Special emphasis is placed on physiological adaptations: water, electrolyte, nitrogen, and thermal balance and their endocrine control are treated in detail. Development and metamorphosis, larval competition for food resources, and reproductive strategies are only a few of the exciting topics in the chapter on ecological aspects.
