Why Big Fierce Animals Are Rare - An Ecologist's Perspective (Paperback): Paul A. Colinvaux Why Big Fierce Animals Are Rare - An Ecologist's Perspective (Paperback)
Paul A. Colinvaux; Foreword by Cristina Eisenberg
R525 R440 Discovery Miles 4 400 Save R85 (16%) Ships in 10 - 15 working days

First published in 1979, Why Big Fierce Animals Are Rare has established itself as a seminal work in ecology. Now with a new foreword by ecologist and writer Cristina Eisenberg, this penetrating study of ecosystems and animal populations is more relevant than ever. What accounts for the many different species of insect? Why does the robin population stay relatively steady year after year, despite the fact that their nests contain several chicks at once? Paul Colinvaux traces the ecologist's quest to answer these questions and more in this accessibly written book. He brings to the subject both profound knowledge and an enthusiasm that will encourage a greater understanding of the environment and of the efforts of those who seek to preserve it.

The Ecology of Invasions by Animals and Plants (Paperback, New edition): Charles S. Elton The Ecology of Invasions by Animals and Plants (Paperback, New edition)
Charles S. Elton
R764 Discovery Miles 7 640 Ships in 9 - 15 working days

Much as Rachel Carson's "Silent Spring" was a call to action against the pesticides that were devastating bird populations, Charles S. Elton's classic "The Ecology of Invasions by Animals and Plants" sounded an early warning about an environmental catastrophe that has become all too familiar today--the invasion of nonnative species. From kudzu to zebra mussels to Asian long-horned beetles, nonnative species are colonizing new habitats around the world at an alarming rate thanks to accidental and intentional human intervention. One of the leading causes of extinctions of native animals and plants, invasive species also wreak severe economic havoc, causing $79 billion worth of damage in the United States alone.
Elton explains the devastating effects that invasive species can have on local ecosystems in clear, concise language and with numerous examples. The first book on invasion biology, and still the most cited, Elton's masterpiece provides an accessible, engaging introduction to one of the most important environmental crises of our time.
Charles S. Elton was one of the founders of ecology, who also established and led Oxford University's Bureau of Animal Population. His work has influenced generations of ecologists and zoologists, and his publications remain central to the literature in modern biology.
"History has caught up with Charles Elton's foresight, and "The Ecology of Invasions" can now be seen as one of the central scientific books of our century."--David Quammen, from the Foreword to "Killer Algae: The True Tale of a Biological Invasion"

Phylogenetics and Ecology, Volume 17 (Hardcover): Paul Eggleton, Richard I. Vane-Wright Phylogenetics and Ecology, Volume 17 (Hardcover)
Paul Eggleton, Richard I. Vane-Wright
R3,661 Discovery Miles 36 610 Ships in 12 - 17 working days

The relationship between systematics and ecology has recently been invigorated, and developed a long way from the "old" field of comparative biology. This change has been two-fold. Advances in phylogenetic research have allowed explicit phylogenetic hypotheses to be constructed for a range of different groups of organisms, and ecologists are now more aware that organism traits are influenced by the interaction of past and present. This volume discusses the impact of these modern phylogenetic methods on ecology, especially those using comparative methods.
Although unification of these areas has proved difficult, a number of conclusions can be drawn from the text. These include the need for a "working" bridge between evolutionary biologists using logic-based cladistic methods and those using probability-based statistical methods, for care in the selection of tree types for comparative studies and for systematists to attempt to analyse ecologically important groups.
Comparative ecologists and systematists need to come together to develop these ideas further, but this volume presents a very useful starting point for all those interested in systematics and ecology.

Australian Deserts - Ecology and Landscapes (Paperback): Steve Morton Australian Deserts - Ecology and Landscapes (Paperback)
Steve Morton
R1,551 Discovery Miles 15 510 Ships in 12 - 17 working days

Australian Deserts: Ecology and Landscapes is about the vast sweep of the Outback, a land of expanses making up three-quarters of the continent - the heart of Australia. Steve Morton brings his extensive first-hand knowledge and experience of arid Australia to this book, explaining how Australian deserts work ecologically. This book outlines why unpredictable rainfall and paucity of soil nutrients underpin the nature of desert ecosystems, while also describing how plants and animals came to be desert dwellers through evolutionary time. It shows how plants use uncertain rainfall to provide for persistence of their populations, alongside outlines of the dominant animals of the deserts and explanations of the features that help them succeed in the face of aridity and uncertainty. Richly illustrated with the photographs of Mike Gillam, this fascinating and accessible book will enhance your understanding of the nature of arid Australia. FEATURES: Describes how Australian deserts work ecologically and how plants and animals came to be desert dwellers through evolutionary time. Outlines two key features of arid Australia, uncertain rainfall and paucity of soil nutrients, that underpin the nature of its ecosystems. Shows how plants use uncertain rainfall to provide for persistence of their populations. Outlines the dominant animals of the deserts and explains the features that help them succeed in the face of aridity and uncertainty. Features stunning images by renowned photographer Mike Gillam.

Population Fluctuations in Rodents (Hardcover): Charles J. Krebs Population Fluctuations in Rodents (Hardcover)
Charles J. Krebs
R1,868 Discovery Miles 18 680 Ships in 12 - 17 working days

How did rodent outbreaks in Germany help to end World War I? What caused the destructive outbreak of rodents in Oregon and California in the late 1950s, the large population outbreak of lemmings in Scandinavia in 2010, and the great abundance of field mice in Scotland in the spring of 2011? Population fluctuations, or outbreaks, of rodents constitute one of the classic problems of animal ecology, and in "Population Fluctuations in Rodents", Charles J. Krebs sifts through the last eighty years of research to draw out exactly what we know about rodent outbreaks and what should be the agenda for future research. Krebs has synthesized the research in this area, focusing mainly on the voles and lemmings of the Northern Hemisphere - his primary area of expertise - but also referring to the literature on rats and mice. He covers the patterns of changes in reproduction and mortality and the mechanisms that cause these changes - including predation, disease, food shortage, and social behavior - and discusses how landscapes can affect population changes, methodically presenting the hypotheses related to each topic before determining whether or not the data supports them. He ends on an expansive note, by turning his gaze outward and discussing how the research on rodent populations can apply to other terrestrial mammals. Geared toward advanced undergraduates, graduate students, and practicing ecologists interested in rodent population studies, this book will also appeal to researchers seeking to manage rodent populations and to understand outbreaks in both natural and urban settings - or, conversely, to protect endangered species.

Integrative Wildlife Nutrition (Hardcover, 2009 ed.): Perry S. Barboza, Katherine L. Parker, Ian D. Hume Integrative Wildlife Nutrition (Hardcover, 2009 ed.)
Perry S. Barboza, Katherine L. Parker, Ian D. Hume
R4,538 Discovery Miles 45 380 Ships in 10 - 15 working days

Nutrition spans a wide range of mechanisms from acquisition of food to digestion, absorption and retention of energy substrates, water and other nutrients. Nutritional principles have been applied to improving individual health, athletic performance and longevity of humans and of their companion animals, and to maximizing agricultural efficiency by manipulating reproduction or growth of tissues such as muscle, hair or milk in livestock. Comparative nutrition borrows from these tra- tional approaches by applying similar techniques to studies of ecology and physiology of wildlife. Comparative approaches to nutrition integrate several levels of organization because the acquisition and flow of energy and nutrients connect individuals to populations, populations to communities, and communities to ecosystems. Integrative Wildlife Nutrition connects behavioral, morphological and biochemical traits of animals to the life history of species and thus the dynamics of populations. An integrated approach to nutrition provides a practical framework for understanding the interactions between food resources and wildlife popu- tions and for managing the harvest of abundant species and the conservation of threatened populations. This book is for students and professionals in animal physiology and ecology, conservation biology and wildlife management. It is based on our lectures, dem- strations and practical classes taught in the USA, Canada and Australia over the last three decades. Instructors can use Integrative Wildlife Nutrition as a text in wildlife and conservation biology programs, and as a reference source for related courses in wildlife ecology.

The Blue Tit (Hardcover): Martyn Stenning The Blue Tit (Hardcover)
Martyn Stenning
R1,729 Discovery Miles 17 290 Ships in 12 - 17 working days

Sporting a mix of blue, yellow, white, green and black, the unmistakable Blue Tit reflects the colours of a planet affected by a burgeoning human population. Fortunately, Blue Tits are adapting well to modern humanity, taking advantage of our propensity to feed birds in our gardens and provide boxes for them to nest in. In turn, this feisty little species provides an excellent model for biological research. This book is the result of a personal quest by author Martyn Stenning to bring together a range of discoveries into one accessible volume. The Blue Tit begins by inviting readers into the intimate lives of these birds as they attempt to reproduce, describing the many challenges they face when rearing their offspring. The story moves on to the fluid state of Blue Tit classification across the native Palearctic range, before progressing into population structure, lifetime ecology and an exploration of factors that determine breeding success. It culminates with an in-depth look at research over the years, followed by a selection of personal anecdotes and an overview of Blue Tit appearances in folklore and poetry. This book provides a definitive record of the biology and ecology of one of our most popular, intelligent and charismatic birds.

"Spatial Ecology" addresses the fundamental effects of space on the dynamics of individual species and on the structure, dynamics, diversity, and stability of multispecies communities. Although the ecological world is unavoidably spatial, there have been few attempts to determine how explicit considerations of space may alter the predictions of ecological models, or what insights it may give into the causes of broad-scale ecological patterns. As this book demonstrates, the spatial structure of a habitat can fundamentally alter both the qualitative and quantitative dynamics and outcomes of ecological processes.

"Spatial Ecology" highlights the importance of space to five topical areas: stability, patterns of diversity, invasions, coexistence, and pattern generation. It illustrates both the diversity of approaches used to study spatial ecology and the underlying similarities of these approaches. Over twenty contributors address issues ranging from the persistence of endangered species, to the maintenance of biodiversity, to the dynamics of hosts and their parasitoids, to disease dynamics, multispecies competition, population genetics, and fundamental processes relevant to all these cases. There have been many recent advances in our understanding of the influence of spatially explicit processes on individual species and on multispecies communities. This book synthesizes these advances, shows the limitations of traditional, non-spatial approaches, and offers a variety of new approaches to spatial ecology that should stimulate ecological research.

Killing, Capture, Trade and Ape Conservation: Volume 4 (Hardcover): Arcus Foundation Killing, Capture, Trade and Ape Conservation: Volume 4 (Hardcover)
Arcus Foundation
R2,518 Discovery Miles 25 180 Ships in 12 - 17 working days

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.

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.

R2,132 Discovery Miles 21 320 Ships in 12 - 17 working days

The great white shark, Carcharodon carcharias, is a marquee predator made famous by movie and myth. This text brings together the real evidence of both ecology and behaviour of these animals. This international team of separates fact from fiction and establishes a baseline from which additional research of great white sharks and sharks in general might proceed. The chapters are divided into sections on the geographic distribution, evolutionary history, behaviour with particular emphasis on the predatory relationship to seals and sea lions, movements and abundance of the species, and its interactions with man. Many of the scientific contributions resulted from the 1993 symposium in Bodega Bay, California, that attracted more than 80 specialists from around the world.

Cognitive Ecology (Paperback, New): Reuven Dukas Cognitive Ecology (Paperback, New)
Reuven Dukas
R1,549 Discovery Miles 15 490 Ships in 12 - 17 working days

How does the environment shape the ways an animal processes information and makes decisions? How do constraints imposed on nervous systems affect an animal's activities? To help answer these questions, "Cognitive Ecology" integrates evolutionary ecology and cognitive science, demonstrating how studies of perception, memory, and learning can deepen our understanding of animal behavior and ecology.
Individual chapters consider such issues as the evolution of learning and its influence on behavior; the effects of cognitive mechanisms on the evolution of signaling behavior; how neurobiological and evolutionary processes have shaped navigational activities; functional and mechanical explanations for altered behaviors in response to changing environments; how foragers make decisions and how these decisions are influenced by the risks of predation; and how cognitive mechanisms affect partner choice.
"Cognitive Ecology" will encourage biologists to consider how animal cognition affects behavior, and will also interest comparative psychologists and cognitive scientists.

Migrating Raptors of the World - Their Ecology and Conservation (Hardcover): Keith L. Bildstein Migrating Raptors of the World - Their Ecology and Conservation (Hardcover)
Keith L. Bildstein
R1,302 Discovery Miles 13 020 Ships in 12 - 17 working days

Many raptors, the hawks, eagles, and falcons of the world, migrate over long distances, often in impressively large numbers. Many avoid crossing wide expanses of water and follow "flyways" to optimize soaring potential. Atmospheric conditions and landscape features, including waterways and mountain ranges, funnel these birds into predictable bottlenecks through which thousands of daytime birds of prey may pass in a short time. Birders and ornithologists also congregate at these locations to observe the river of raptors passing overhead (as did hunters in the United States in the past and in some countries even today).

Keith L. Bildstein has studied migrating raptors on four continents and directs the conservation science program at Hawk Mountain Sanctuary, Pennsylvania, the world's first refuge for migratory birds of prey. In this book, he details the stories and successes of twelve of the world's most important raptor-viewing spots, among them Cape May Point, New Jersey; Veracruz, Mexico; Kekoldi, Costa Rica; the Strait of Gibralter, Spain; and Elat, Israel. During peak migration, when the weather is right, the skies at these sites, as at Hawk Mountain, can fill with thousands of birds in a single field of view. Bildstein, whose knowledge of the phenomenon of raptor migration is comprehensive, provides an accessible account of the history, ecology, geography, science, and conservation aspects surrounding the migration of approximately two hundred species of raptors between their summer breeding sites and their wintering grounds. He summarizes current knowledge about how the birds' bodies handle the demands of long-distance migration and how they know where to go.

Migrating Raptors of the World also includes the ecological and conservation stories of several intriguing raptor migrants, including the Turkey Vulture, Osprey, Bald Eagle, Western Honey Buzzard, Northern Harrier, Grey-faced Buzzard, Steppe Buzzard, and Amur Falcon.

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 Ecological Detective - Confronting Models with Data (MPB-28) (Paperback, New): Ray Hilborn, Marc Mangel The Ecological Detective - Confronting Models with Data (MPB-28) (Paperback, New)
Ray Hilborn, Marc Mangel
R2,692 Discovery Miles 26 920 Ships in 10 - 15 working days

The modern ecologist usually works in both the field and laboratory, uses statistics and computers, and often works with ecological concepts that are model-based, if not model-driven. How do we make the field and laboratory coherent? How do we link models and data? How do we use statistics to help experimentation? How do we integrate modeling and statistics? How do we confront multiple hypotheses with data and assign degrees of belief to different hypotheses? How do we deal with time series (in which data are linked from one measurement to the next) or put multiple sources of data into one inferential framework? These are the kinds of questions asked and answered by "The Ecological Detective."

Ray Hilborn and Marc Mangel investigate ecological data much as a detective would investigate a crime scene by trying different hypotheses until a coherent picture emerges. The book is not a set of pat statistical procedures but rather an approach. The Ecological Detective makes liberal use of computer programming for the generation of hypotheses, exploration of data, and the comparison of different models. The authors' attitude is one of exploration, both statistical and graphical. The background required is minimal, so that students with an undergraduate course in statistics and ecology can profitably add this work to their tool-kit for solving ecological problems.
