This book meets the demand for a comprehensive introduction to understanding the processes of population limitation. Recognized world-wide as a respected biologist and communicator, Dr. Ian Newton has now written a clear and detailed treatise on local scale population limiting factors in birds. It is based almost entirely on results from field studies, though it is set in a contemporary theoretical framework. The 16 chapters fall under three major section headings: Behavior and Density Regulation; Natural Limiting Factors; and Human Impacts. Population Limitation in Birds serves as a needed resource expanding on Dr. David Lacks research in this area of ornithology in the 1950s. It includes numerous line diagrams and beautiful illustrations by acclaimed wildlife artist Keith Brockie. - Provides a sorely needed introduction to a long-established core subject in ornithology - Focuses on local scale factors - Written by a well-known biologist and effective communicator - Includes numerous line diagrams and beautiful illustrations by acclaimed wildlife artist Keith Brockie
The Migration Ecology of Birds, Second Edition covers all aspects of this absorbing subject, including migratory processes, problems of navigation and vagrancy, timing and physiological control of migration, large-scale movement patterns, the effects of recent climate change, the problems that migrants face, and the factors that limit their populations. This book provides a thorough and in-depth review of the state of the science, with the text supplemented by abundant tables, maps and diagrams. Written by a world-renowned avian ecology and migration researcher, this book reveals the extraordinary adaptability of birds to the variable and changing conditions across the globe. This book represents the most updated and detailed review of bird migration, its evolution, ecology and bird physiology. Written in a clear and readable style, it will appeal not only to migration researchers in the field and ornithologists, but to anyone with an interest in this fascinating subject. - Features updated and trending ecological aspects, including various types of bird movements, dispersal and nomadism, and how they relate to food supplies and other external conditions - Contains numerous tables, maps, diagrams, a glossary, and a bibliography of more than 3,000 up-to-date references - Written by an active researcher with a distinguished career in avian ecology, including migration research
There are more than one thousand species of threatened birds in the world, while many others are valued for sport and some are serious pests. This volume reviews our current understanding of avian population dynamics and explores ways in which population studies can contribute to effective conservation and management. Estimation of demographic parameters, the role of mathematical modelling, and the special problems of island populations and seabird populations are discussed. The emphasis throughout is on how bird populations are regulated under various constraints and conditions, including the impact of environmental changes.
This book should be of value to anyone interested in bird evolution and taxonomy, biogeography, distributional history, dispersal and migration patterns. It provides an up-to-date synthesis of current knowledge on species formation, and the factors influencing current distribution patterns. It draws heavily on new information on Earth history, including past glacial and other climatic changes, on new developments in molecular biology and palaeontology, and on recent studies of bird distribution and migration patterns, to produce a coherent account of the factors that have influenced bird species diversity and distribution patterns worldwide. Received the Best Bird Book of the Year award for 2004 from British Birds magazine. * Winner of the British Birds/British Trust for Ornithology, Bird Book of the Year 2004! * The first book to deal comprehensively with bird speciation and biogeography * Up-to-date synthesis of new information * Clearly written * No previous book covers the same ground * Many maps and diagrams * Makes difficult and widely scattered information accessible and easily understood * A sound base for future research * Takes full account of recent developments in molecular biology
“Rigorous and well defended . . . Faaborg makes many fresh and, in some cases, provocative points regarding management guidelines for migrant birds.” —Kenneth Able, Great Plains Research In the 1980s, numerous scientific surveys documented both declining bird populations, especially among Neotropical songbirds that winter in the tropics, and the loss of tropical rain forest habitat. Drawing the seemingly obvious conclusion, scientists and environmental activists linked songbird declines to loss of tropical habitats and alerted the world to an impending ecological catastrophe. Their warnings led to the establishment of the Neotropical Migratory Bird Conservation Program, also known as Partners in Flight, the self-proclaimed largest conservation effort in history. Looking back over more than a decade of efforts to save migrant birds, John Faaborg offers the first serious evaluation of the state of songbird populations today, the effectiveness of conservation programs such as Partners in Flight, and the reliability and completeness of scientific research on migrant birds. Taking neither an alarmist nor a complacent approach, he shows that many factors besides habitat loss affect bird populations and that Neotropical migrants as a group are not declining dramatically, though some species adapt to habitat alteration more successfully than others. Faaborg’s state-of-the-art survey thus clarifies the kinds of information we will need and the conservation efforts we should undertake to ensure the long-term survival of Neotropical migrant birds. “Presents a carefully and closely reasoned argument about the magnitude of the conservation problems facing migrant birds, how we can reduce these problems, and how current conservation efforts have enormous value even if there is no immediate crisis.” —Scott K. Robinson, Professor and Head, Department of Animal Biology, University of Illinois
In the latest addition to the New Naturalist series, Ian Newton explores bird populations and what causes their fluctuation – food supplies, competitors, predators, parasites, pathogens and human activity.
For centuries biologists have tried to understand the underpinnings of avian migration: where birds go and why, why some migrate and some do not, how they adapt to a changing environment, and how migratory systems evolve. Twenty-five years ago the answers to many of these questions were addressed by a collection of migration experts in Keast and Morton's classic work Migrant Birds in the Neotropics. In 1992, Hagan and Johnston published a follow-up book, Ecology and Conservation of Neotropical Migrant Landbirds. In Birds of Two Worlds Russell Greenberg and Peter Marra bring together the world's experts on avian migration to discuss its ecology and evolution. The contributors move the discussion of migration to a global stage, looking at all avian migration systems and delving deeper into the evolutionary foundations of migratory behavior. Readers interested in the biology, behavior, ecology, and evolution of birds have waited a decade to see a worthy successor to the earlier classics. Birds of Two Worlds will complete the trilogy and become indispensable for ornithologists, evolutionary biologists, serious birders, and public and academic libraries.
This accessible textbook focuses on the dynamics of infectious diseases for wild avian hosts across every level of ecological hierarchy. Although the topics and principles discussed in this book relate to birds, they have a far wider relevance and can also be applied to non-avian, wildlife host-pathogen systems.
