Trophic Cascades by John Terborgh,James A Estes Pdf

Trophic cascades—the top-down regulation of ecosystems by predators—are an essential aspect of ecosystem function and well-being. Trophic cascades are often drastically disrupted by human interventions—for example, when wolves and cougars are removed, allowing deer and beaver to become destructive—yet have only recently begun to be considered in the development of conservation and management strategies. Trophic Cascades is the first comprehensive presentation of the science on this subject. It brings together some of the world’s leading scientists and researchers to explain the importance of large animals in regulating ecosystems, and to relate that scientific knowledge to practical conservation. Chapters examine trophic cascades across the world’s major biomes, including intertidal habitats, coastal oceans, lakes, nearshore ecosystems, open oceans, tropical forests, boreal and temperate ecosystems, low arctic scrubland, savannas, and islands. Additional chapters consider aboveground/belowground linkages, predation and ecosystem processes, consumer control by megafauna and fire, and alternative states in ecosystems. An introductory chapter offers a concise overview of trophic cascades, while concluding chapters consider theoretical perspectives and comparative issues. Trophic Cascades provides a scientific basis and justification for the idea that large predators and top-down forcing must be considered in conservation strategies, alongside factors such as habitat preservation and invasive species. It is a groundbreaking work for scientists and managers involved with biodiversity conservation and protection.

Cascade Predator by Rob Phillips Pdf

With two major investigations now closed, fish and wildlife police officer Luke McCain is called upon for his most high-profile case yet. En route to the Washington State Fair, an exotic cat show's trailer is stolen. After some of the big cats are released into the Cascade Mountains, McCain and his dog Jack try to locate the show's most menacing member: a Bengal tiger. Meanwhile, there are rumblings that a wild cougar has killed a dirt biker in the region. While news crews flock to McCain's neck of the woods, he must stay on the trail of both big cats before anyone else falls prey to the predators.

The Cascade Killer by Rob Phillips Pdf

As a Fish and Wildlife police officer, Luke McCain and his partner -- a yellow Labrador named Jack -- spend their days patrolling the rivers, lakes and forests of the wild and scenic Cascade Mountains in Eastern Washington. After hunters discover human remains inside a bear's stomach, McCain is thrust into the investigation. As more dead women are found in McCain's region, authorities suspect a serial killer is prowling the mountains he knows best. McCain will need his knowledge as an outdoorsman, and his instincts as an investigator, to track the psychopathic predator before he kills again.

Food Webs: From Connectivity to Energetics by Anonim Pdf

The most recent volume of this series, Advances in Ecological Research, demonstrates a captivating knowledge of recent advances in the analysis of food webs. A food web describes the network of predator-prey interactions within a community. The simplest description of a food web specifies only who eats whom (a connectance web), with no indication of how much or how often. Chapters in this book begin with a discussion of the most detailed connectance webs ever compiled, and advance to incorporate information on the body size and numerical abundance of the species. The results yield new ways of describing food webs and powerful new models for estimating patterns of energy flow in ecosystems. Provides fresh ways of describing food webs and applies previous observations in a new context Ranked as the #1 publication in the Institute for Scientific Information in the Ecology section of 2000 Powerful new theory AND application to some of the best food web data in the world Many mathematical models for food web structure and function Integrates previously unconnected perspectives on the description of ecological communities

Introduction to Population Ecology by Larry L. Rockwood Pdf

Introduction to Population Ecology, 2nd Edition is a comprehensive textbook covering all aspects of population ecology. It uses a wide variety of field and laboratory examples, botanical to zoological, from the tropics to the tundra, to illustrate the fundamental laws of population ecology. Controversies in population ecology are brought fully up to date in this edition, with many brand new and revised examples and data. Each chapter provides an overview of how population theory has developed, followed by descriptions of laboratory and field studies that have been inspired by the theory. Topics explored include single-species population growth and self-limitation, life histories, metapopulations and a wide range of interspecific interactions including competition, mutualism, parasite-host, predator-prey and plant-herbivore. An additional final chapter, new for the second edition, considers multi-trophic and other complex interactions among species. Throughout the book, the mathematics involved is explained with a step-by-step approach, and graphs and other visual aids are used to present a clear illustration of how the models work. Such features make this an accessible introduction to population ecology; essential reading for undergraduate and graduate students taking courses in population ecology, applied ecology, conservation ecology, and conservation biology, including those with little mathematical experience.

The Biology of Grasslands by Brian Wilsey Pdf

This accessible text provides a concise but comprehensive introduction to the biology of global grasslands. Grasslands are vast in their extent, with native and non-native grasslands now covering approximately 50% of the global terrestrial environment. They are also of vital importance to humans, providing essential ecosystem services and some of the most important areas for the production of food and fibre worldwide. It has been estimated that 60% of calories consumed by humans originate from grasses, and most grain consumed is produced in areas that were formerly grasslands or wetlands. Grasslands are also important because they are used to raise forage for livestock, represent a source of biofuels, sequester vast amounts of carbon, provide urban green-space, and hold vast amounts of biodiversity. Intact grasslands contain an incredibly fascinating set of plants, animals, and microbes that have interested several generations of biologists, generating pivotal studies to important theoretical questions in ecology. As with other titles in the Biology of Habitats Series, the emphasis is on the organisms that dominate this environment although restoration, conservation, and experimental aspects are also considered.

Amphibian Declines by Michael Lannoo Pdf

This benchmark volume documents in comprehensive detail a major environmental crisis: rapidly declining amphibian populations and the disturbing developmental problems that are increasingly prevalent within many amphibian species. Horror stories on this topic have been featured in the scientific and popular press over the past fifteen years, invariably asking what amphibian declines are telling us about the state of the environment. Are declines harbingers of devastated ecosystems or simply weird reflections of a peculiar amphibian world? This compendium—presenting new data, reviews of current literature, and comprehensive species accounts—reinforces what scientists have begun to suspect, that amphibians are a lens through which the state of the environment can be viewed more clearly. And, that the view is alarming and presages serious concerns for all life, including that of our own species. The first part of this work consists of more than fifty essays covering topics from the causes of declines to conservation, surveys and monitoring, and education. The second part consists of species accounts describing the life history and natural history of every known amphibian species in the United States.

The Biology and Ecology of Giant Kelp Forests by David R. Schiel,Michael S. Foster Pdf

The largest seaweed, giant kelp (Macrocystis) is the fastest growing and most prolific of all plants found on earth. Growing from the seafloor and extending along the ocean surface in lush canopies, giant kelp provides an extensive vertical habitat in a largely two-dimensional seascape. It is the foundation for one of the most species-rich, productive, and widely distributed ecological communities in the world. Schiel and Foster’s scholarly review and synthesis take the reader from Darwin’s early observations to contemporary research, providing a historical perspective for the modern understanding of giant kelp evolution, biogeography, biology, and physiology. The authors furnish a comprehensive discussion of kelp species and forest ecology worldwide, with considerations of human uses and abuses, management and conservation, and the current and likely future impacts of global change. This volume promises to be the definitive treatise and reference on giant kelp and its forests for many years, and it will appeal to marine scientists and others who want a better appreciation and understanding of these wondrous forests of the sea.

Behavioural Responses to a Changing World by Ulrika Candolin,Bob B. M. Wong Pdf

Human-induced environmental change currently represents the single greatest threat to global biodiversity. Species are typically adapted to the local environmental conditions in which they have evolved. Changes in environmental conditions initially influence behaviour, which in turn affects species interactions, population dynamics, evolutionary processes and, ultimately, biodiversity. How animals respond to changed conditions, and how this influences population viability, is an area of growing research interest. Yet, despite the vital links between environmental change, behaviour, and population dynamics, surprisingly little has been done to bridge these areas of research. Behavioural Responses to a Changing World is the first book of its kind devoted to understanding behavioural responses to environmental change. The volume is comprehensive in scope, discussing impacts on both the mechanisms underlying behavioural processes, as well as the longer-term ecological and evolutionary consequences. Drawing on international experts from across the globe, the book covers topics as diverse as endocrine disruption, learning, reproduction, migration, species interactions, and evolutionary rescue.
