The City Is More Than Human - An Animal History of Seattle (Paperback): Frederick L Brown The City Is More Than Human - An Animal History of Seattle (Paperback)
Frederick L Brown; Foreword by Paul S. Sutter
R650 Discovery Miles 6 500 Ships in 12 - 17 working days

Winner of the 2017 Virginia Marie Folkins Award, Association of King County Historical Organizations (AKCHO) Winner of the 2017 Hal K. Rothman Book Prize, Western History Association Seattle would not exist without animals. Animals have played a vital role in shaping the city from its founding amid existing indigenous towns in the mid-nineteenth century to the livestock-friendly town of the late nineteenth century to the pet-friendly, livestock-averse modern city. When newcomers first arrived in the 1850s, they hastened to assemble the familiar cohort of cattle, horses, pigs, chickens, and other animals that defined European agriculture. This, in turn, contributed to the dispossession of the Native residents of the area. However, just as various animals were used to create a Euro-American city, the elimination of these same animals from Seattle was key to the creation of the new middle-class neighborhoods of the twentieth century. As dogs and cats came to symbolize home and family, Seattleites' relationship with livestock became distant and exploitative, demonstrating the deep social contradictions that characterize the modern American metropolis. Throughout Seattle's history, people have sorted animals into categories and into places as a way of asserting power over animals, other people, and property. In The City Is More Than Human, Frederick Brown explores the dynamic, troubled relationship humans have with animals. In so doing he challenges us to acknowledge the role of animals of all sorts in the making and remaking of cities.

The Laws Protecting Animals and Ecosystems (Hardcover): P.A. Rees The Laws Protecting Animals and Ecosystems (Hardcover)
P.A. Rees
R3,135 Discovery Miles 31 350 Ships in 12 - 17 working days

There is currently no basic text in wildlife law suitable for the wide range of courses in wildlife conservation and animal welfare at both bachelors and masters level, or for the large number of people who work in conservation and animal welfare; The Laws Protecting Animals and Ecosystems fills the gap in this significant market for a basic law text applicable to students and professionals whose primary training is in biology but who require a basic understanding of the laws relating to the protection of animals and ecosystems. The text is applicable to a wide range of subjects, including wildlife conservation, animal handling, animal welfare, animal husbandry, and veterinary science. This foundational text supports those studying animal and ecosystem law by providing an overview of the basic legal principles, national and international laws, terminology, the legal mechanisms used to protect animals and ecosystems, and a compendium of the major animal welfare and conservation laws in major English speaking countries. Dr. Rees has been teaching wildlife law for 20 years and ecology for over 35 years and is ideally placed to write this book.

R1,533 Discovery Miles 15 330 Ships in 9 - 15 working days

Urban Evolutionary Biology fills an important knowledge gap on wild organismal evolution in the urban environment, whilst offering a novel exploration of the fast-growing new field of evolutionary research. The growing rate of urbanization and the maturation of urban study systems worldwide means interest in the urban environment as an agent of evolutionary change is rapidly increasing. We are presently witnessing the emergence of a new field of research in evolutionary biology. Despite its rapid global expansion, the urban environment has until now been a largely neglected study site among evolutionary biologists. With its conspicuously altered ecological dynamics, it stands in stark contrast to the natural environments traditionally used as cornerstones for evolutionary ecology research. Urbanization can offer a great range of new opportunities to test for rapid evolutionary processes as a consequence of human activity, both because of replicate contexts for hypothesis testing, but also because cities are characterized by an array of easily quantifiable environmental axes of variation and thus testable agents of selection. Thanks to a wide possible breadth of inference (in terms of taxa) that may be studied, and a great variety of analytical methods, urban evolution has the potential to stand at a fascinating multi-disciplinary crossroad, enriching the field of evolutionary biology with emergent yet incredibly potent new research themes where the urban habitat is key. Urban Evolutionary Biology is an advanced textbook suitable for graduate level students as well as professional researchers studying the genetics, evolutionary biology, and ecology of urban environments. It is also highly relevant to urban ecologists and urban wildlife practitioners.

R4,205 Discovery Miles 42 050 Ships in 12 - 17 working days

Until recently, the production of fruits by plants, their consumption by animals (frugivory) and the relevance of these to seed dispersal have attracted less attention than topics such as pollination biology. However, since the 1970s they have started to gain more prominence and now give rise to more research funding, seminal papers and international symposiums. This book contains chapters adapted from the Third International Symposium-Workshop on Frugivores and Seed Dispersal held in August 2000, in Rio Quente, Brazil.

Corrado Battisti, Gianluca Poeta, Giuliano Fanelli
R3,740 Discovery Miles 37 400 Ships in 10 - 15 working days

This book represents an introductory review of disturbance ecology and threat analysis, providing schematic concepts and approaches useful for work on sites that are affected by the impact of human actions. It is aimed at conservation and environmental practitioners, who will find tips for choosing methods and approaches when there are conflicts between the natural components and human activity. It is also addressed to students of applied ecology, ecosystem management, land-use planning and environmental impact assessment. It discusses a number of topics covered in the programs of many university courses related to basic ecology and ecology of disturbance, the latter constituting a field of great interest because of its implications and repercussions in applied territorial science. The book is divided into two parts: the first focuses on the theoretical and disciplinary framework of the ecology of disturbance, while the second is devoted to the analysis of anthropogenic threats. This, in particular, discusses the most recent approach, which uses a conventional nomenclature to allow a coarse-grained quantification and objective assessment of threat impact on different environmental components. Such an approach facilitates the comparison of hierarchically different events and, therefore, helps define the priorities for management and conservation strategies.

Covering a range of metaphors from a diverse field of sciences, from cell and molecular biology to evolution, ecology, and biomedicine, Understanding Metaphors in the Life Sciences explores the positive and negative implications of the widespread use of metaphors in the biological and life sciences. From genetic codes, programs, and blueprints, to cell factories, survival of the fittest, the tree of life, selfish genes, and ecological niches, to genome editing with CRISPR's molecular scissors, metaphors are ubiquitous and vital components of the modern life sciences. But how exactly do metaphors help scientists to understand the objects they study? How can they mislead both scientists and laypeople alike? And what should we all understand about the implications of science's reliance on metaphorical speech and thought for objective knowledge and adequate public policy informed by science? This book will literally help you to better understand the metaphorical dimensions of science.

With the abstracts arranged by organismal group and placed in chronological order, the chapters in this book lead readers on a fascinating historical journey into the realm of molecular genetics as applied across the past four decades to intriguing questions in ecology, evolution, animal behavior, and natural history.

Cetacean Societies (Paperback, New): Janet Mann Cetacean Societies (Paperback, New)
Janet Mann
R2,406 Discovery Miles 24 060 Ships in 12 - 17 working days

"Part review, part testament to extraordinary dedication, and part call to get involved, "Cetacean Societies" highlights the achievements of behavioral ecologists inspired by the challenges of cetaceans and committed to the exploration of a new world."--from the preface by Richard Wrangham
Long-lived, slow to reproduce, and often hidden beneath the water's surface, whales and dolphins (cetaceans) have remained elusive subjects for scientific study even though they have fascinated humans for centuries. Until recently, much of what we knew about cetaceans came from commercial sources such as whalers and trainers for dolphin acts. Innovative research methods and persistent efforts, however, have begun to penetrate the depths to reveal tantalizing glimpses of the lives of these mammals in their natural habitats.
"Cetacean Societies" presents the first comprehensive synthesis and review of these new studies. Groups of chapters focus on the history of cetacean behavioral research and methodology; state-of-the-art reviews of information on four of the most-studied species: bottlenose dolphins, killer whales, sperm whales, and humpback whales; and summaries of major topics, including group living, male and female reproductive strategies, communication, and conservation drawn from comparative research on a wide range of species.
Written by some of the world's leading cetacean scientists, this landmark volume will benefit not just students of cetology but also researchers in other areas of behavioral and conservation ecology as well as anyone with a serious interest in the world of whales and dolphins.
Contributors are Robin Baird, Phillip Clapham, Jenny Christal, Richard Connor, Janet Mann, Andrew Read, Randall Reeves, Amy Samuels, Peter Tyack, Linda Weilgart, Hal Whitehead, Randall S. Wells, and Richard Wrangham.

Arctic and Subarctic North America is particularly affected by climate change, where average temperatures are rising three times faster than the global average. Documenting the changing climate/environment of the north requires a structured knowledge of indicator taxa that reflect the effects of climate changes.Aleocharine beetles are a dominant group of forest insects, which are being used in many projects as indicators of environmental change. Many species are forest specialists restricted to certain microhabitats, some are generalists and others are open habitat specialists. They represent many ecological niches and, as such, are good indicators for many other species as well. The majority of Canadian aleocharine beetle species (about 600 spp.) has been studied and published by Jan Klimaszewski et al. (2018, 2020), mainly from southern, central, and western Canada, while the northern taxa remain poorly known and documented. The aim of the present book is to summarize the knowledge on this insect group in the Arctic and Subarctic North America and to provide a diagnostic and ecological tool for scientists studying and monitoring insects in northern Canada and Alaska. The book includes a review of the literature, information on 238 species and their habitats, taxonomic review, images, and identification tools.

R5,775 Discovery Miles 57 750 Ships in 10 - 15 working days

Deep-water coral reefs are found along large sections of the outer continental shelves and slopes of Europe, from North Cape to the Gulf of Cadiz, and because they also occur along the Atlantic seaboard of USA, the Gulf of Mexico, off Brazil, in the Mediterranean, and off New Zealand, they are currently being targeted by international groups of marine scientists. They have become popular and opportune deep-water research targets because they offer exciting frontier exploration, combined with a whole plethora of modern scientific methods, such as deep-sea drilling, sampling, remote control surveying and documentation. Furthermore they represent timely opportunities for further developments within the application of geochemistry, stable isotope research, bacterial sciences, including DNA-sequestering, and medical research (search for bioactive compounds). The Integrated Ocean Drilling Program (IODP) has arranged a deep-sea scientific drilling campaign on giant carbonate banks off Ireland. Because the reefs currently defy traditional marine-ecological theories, they represent future research opportunities and will enjoy scientific scrutiny for many years to come.

Alan A. Berryman, Pavel Kindlmann
R1,557 Discovery Miles 15 570 Ships in 10 - 15 working days

This unique book is concerned with the general principles and theories of population ecology, based on the idea that the rules governing the dynamics of populations are relatively simple, and that the rich behavior we observe in nature is a consequence of the structure of the system rather than of the complexity of the underlying rules. From this perspective, the dynamic behavior of single-species populations is examined and an elementary feedback model of the population system is developed. This single-species model is refined and generalized by examining the mechanisms of population regulation.

R5,778 Discovery Miles 57 780 Ships in 10 - 15 working days

Jellyfish are one of the most conspicuous animals in our oceans and are renowned for their propensity to form spectacular blooms. The unique features of the biology and ecology of jellyfish that enable them to bloom also make them successful invasive species and, in a few places around the world, jellyfish have become problematic. As man increasingly populates the world s coastlines, interactions between humans and jellyfish are rising, often to the detriment of coastal-based industries such as tourism, fishing and power generation. However we must not lose sight of the fact that jellyfish have been forming blooms in the oceans for at least 500 million years, and are an essential component of normal, healthy ocean ecosystems. Here many of the world s leading jellyfish experts explore the science behind jellyfish blooms. We examine the unique features of jellyfish biology and ecology that cause populations to bloom and bust, and, using case studies, we show why jellyfish are important to coastal and ocean ecosystem function. We outline strategies coastal managers can use to mitigate the effects of blooms on coastal industries thereby enabling humans to coexist with these fascinating creatures. Finally we highlight how jellyfish benefit society; providing us with food and one of the most biomedically-important compounds discovered in the 20th century. "

A beautifully illustrated and deeply personal chronicle of De Roy's lifelong connection with these spectacular islands Tui De Roy was a year old in 1955 when her family left Europe, boarding a banana boat bound for the Pacific to lead a different sort of life in Galapagos, one of self-sufficiency and living close to nature. She grew up on the islands and returned to them often over the next five decades. Discovering photography at a young age, she has dedicated her life to recording the islands' natural history in infinite detail. A Lifetime in Galapagos is De Roy's intimate portrait of one of the most spectacular places on Earth, presenting the wildlife and natural wonders of Galapagos as you have never seen them before. Featuring hundreds of breathtaking color photos, this stunning book guides you into labyrinthine mangroves to observe nesting herons, to misty cloud forests to glimpse flycatchers and orchids, high onto erupting volcanoes, and into the ocean to swim with hammerhead sharks. De Roy's lens provides up-close encounters with orca and sperm whales, colonies of iguanas, and the giant tortoises of Alcedo Volcano. She paints unforgettable portraits of her childhood in Galapagos-the islands at night under the stars of the Milky Way, sea lions at play and on the hunt, the diverse birdlife of Galapagos, and much more. Blending striking images with vivid prose, A Lifetime in Galapagos also discusses the threats that global warming and other environmental challenges pose to the archipelago's unique wildlife and fragile habitats.

R4,470 Discovery Miles 44 700 Ships in 10 - 15 working days

By the end of the 19th century both beaver species had been extirpated from large portions of their native ranges. The global decline in beaver populations was the direct re sult of exploitation by humans. Now, at the end of the 20th century, protection, manage ment, and reintroduction programs, coupled with a decline in the demand for beaver fur and other products, have allowed beaver populations to increase dramatically. Since bea vers actively modify their local environment their activities can conflict with human land use. Because of this, the beaver, once considered a unique and exotic component of wet lands, is now often considered a nuisance species. The history, as well as the current status, of beaver populations in Europe and North America provide insight into how con servation programs work, and into how humans and wildlife interact. The initial plenary lecture of the Euro-American Mammal Congress (July, 1998) was presented by Dr. Michael L. Rosenzweig, a professor at the University of Arizona. Dr. Rosenzweig discussed how humans have used and continue to use natural resources, in cluding wildlife and wildland. He provided evidence indicating that the current model of reservation conservation could not provide a long-term solution to the human-wild life/wildland conflict. Dr. Rosenzweig emphasized that what is required is a move away from purely exploitive activities (I would call this exploitive ecology) and the develop ment of a reconciliation ecology with wildlife.

R4,561 Discovery Miles 45 610 Ships in 10 - 15 working days

Leaping Ahead: Advances in Prosimian Biology presents a summary of the state of prosimian biology as we move into the second decade of the 21st century. The book covers a wide range of topics, from assessments of diversity and evolutionary scenarios, through ecophysiology, cognition, behavioral and sensory ecology, to the conservation and survival prospects of this extraordinary and diverse group of mammals. The collection was inspired by an international conference in Ithala, KwaZulu-Natal, South Africa in 2007, where prosimian biologists gathered from Canada, Finland, France, Germany, India, Italy, Japan, Madagascar, South Africa, Tanzania, the United Kingdom, and the United States of America. The meeting reverberated with the passion prosimian researchers feel for their study subjects and with their deep concern for the future of prosimians in the face of ongoing habitat destruction and the burgeoning threat of bushmeat hunting. Chapters for this volume were contributed by researchers from across the globe; they attest to the diversity, vibrancy and rapid growth of prosimian biology, and to the intellectual advances that have revolutionized this field in recent years. Since its earliest beginnings, prosimian research and its resultant literature have had a strong francophone component, and researchers in many prosimian habitat countries are more comfortable reading and writing in French rather than English. French summaries of all chapters have been included. The volume is targeted at researchers, both those entering the field and established scientists, who have an interest in the biology of primates and small mammals. It is also aimed at conservation biologists seeking a deeper understanding of the faunas and conservation developments in Africa, Madagascar and Southeast Asia, and anyone who has an interest in discovering the true diversity of our order, the Primates.

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.

The welfare of domestic poultry. particularly those kept under intensive housing conditions is a subject ~n which many. often divergent and conflicting views. are held. This divergence, may be the result either of insufficient knowledge of the facts of particular poultry husbandry systems or a differing interpretation of those facts. With regard to poultry and the laying hen in particular. there is a need to gather together a basic knowledge of avian behaviour in all the circumstances and systems of husbandry under which birds are presently being kept. That knowledge should lead to the development of interpretative and hopefully predictive theories which in turn will allow us to meet the recommendations of Article 3 of the Council of Europe Convention on the Protection of Animals Kept for Farming Purposes: 'that animals shall be housed, provided with food. water and care in a manner which - having regard to their species and to their degree of development. adaptation and domestication - is appropriate to their physiological and ethological needs in accordance with established experience and scientific knowledge'. In furtherance of those objectives a small group of specialists in poultry physiology and ethology. both from within and outside the European Community met by invitation of the Commission in Luxembourg between 11 and 13 March 1980. Their objective was to discuss what is already known. and can be agreed on. of the normal physiology and ethological range of the laying hen.

The transport of farm livestock was the subject of the seminar held from 7 - 8 July 1981 at the Commission of the European Communities (CECl, Directorate General for Agriculture, Brussels as part of the work of the Division Coordinating Agricultural Research. The aims of the seminar were to examine the knowledge available on how the physiology and behaviour of animals may change during transport; to consider the significance of these changes in relation to welfare and economics and to assess those actions which as experimental projects or observational studies might be proposed to fill the most important gaps in our knowledge of the welfare of farm animals during transport. A number of conclusions can be drawn from the proceedings: 1. Much knowledge is available from both scientific observations and practical experience which could be used to improve the transport of livestock. Methods of loading, the construction of vehicles, ships, crates and aircraft could benefit from the application of existing knowledge. It is less clear whether it is best to concentrate on disseminating existing knowledge by education and advice or to contemplate more regulations. 2. Losses by down-grading at slaughter can largely be attributed to the ways in which animals are transported and handled.

Animal production systems have changed dramatically over the last two decades. Knowledge of energy metabolism and environmental physio logy has increased as appears from many textbooks on these disciplines. The contents of the symposia on energy metabolism of farm animals show this and they have initially focussed on feed evaluation and later on com parative aspects of energy metabolism. They show part of the progress being made. Application of knowledge of energy metabolism for animals has a long history since Lavoisier. In addition to this, studies about the environ mental requirements of animals have shown that we are still far from ac curate assessment of these requirements in terms of nutrients and ener gy. I n model studies on energy metabolism researchers have recognized the interaction between the environment and the energy requirements of animals. Estimation of energy requirements has been done in physiolo gical, physical and behavioural studies. The impact of conditions as en countered by animals in various production systems has been approached from different viewpoints related to these different disciplines. In addi tion, various kinds of infections (bacterial, parasitic: subclinical, clini cal) have been evaluated only recently with regard to their effect on pro tein and/or energy metabolism and thus on production. People working in the field of feed evaluation have defined how che mical and physical properties of nutrition infiuence energy to be derived for maintenance and production.
