Population Fluctuations in Rodents

Population Fluctuations in Rodents: 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 s, the large population outbreak of lemmings in Scandinavia in , and the great abundance of field mice in Scotland in the spring of 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 undergraduate students, 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.

Population Limitation in Birds

ISBN: , SKU: , AUTHOR: Newton, Ian / Brockie, Keith, PUBLISHER: Academic Press, 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 s. It includes numerous line diagrams and beautiful illustrations by acclaimed wildlife artist Keith Brockie. Key Features * 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

Surveillance and Control in Israel/Palestine: Population,

ISBN: , SKU: , AUTHOR: Zureik, Elia / Lyon, David / Abu-Laban, Yasmeen, PUBLISHER: Routledge, Surveillance is always a means to an end, whether that end is influence, management or entitlement. This book examines the several layers of surveillance that control the Palestinian population in Israel and the Occupied Territories, showing how they operate, how well they work, how they are augmented, and how in the end their chief purpose is population control. Showing how what might be regarded as exceptional elsewhere is here regarded as the norm, the book looks not only at the political economy of surveillance and its technological and military dimensions, but also at the ordinary ways that Palestinians in Israel and the occupied territories are affected in their everyday lives. Written in a clear and accessible style by experts in the field, this book will have large appeal for academic faculty as well as graduate and senior undergraduate students in sociology, political science, international relations, surveillance studies and Middle East studies.

Stochastic Population Dynamics in Ecology and Conservation

ISBN: , SKU: , AUTHOR: Lande, Russell / Engen, Steinar / Saether, Bernt-Erik, PUBLISHER: Oxford University Press, USA, Random fluctuations in population dynamics are fundamentally important in pure and applied ecology. This book introduces demographic and environmental stochasticity, and illustrates statistical methods for estimating them from field data. The concept of long-run growth rate of a population is explained and extended to age-structured populations. Diffusion approximations show how stochastic factors affect extinction in single populations and metapopulations. Delayed density dependence in populations with discrete annual reproduction is estimated from time series of adult numbers combined with basic life history data. The spatial scale of population fluctuations and local extinction risk depend on the scales of spatial environmental autocorrelation and individual dispersal, and the strength of density dependence. Stochastic dynamics and statistical uncertainty in population parameters are incorporated in Population Viability Analysis and sustainable harvesting. Statistics of species diversity measures and species abundance distributions are described, with implications for rapid assessments of biodiversity, and methods are developed for partitioning species diversity into components. Analysis of stochastic community dynamics indicates that real communities are far from neutral.

The Malthus Factor: Poverty, Politics and Population in

ISBN: , SKU: , AUTHOR: Ross, Eric B., PUBLISHER: Zed Books, This book represents a major critique of the way Malthusian thinking has influenced capitalist development policy in the modern period, as well as in the past. Taking an historical and comparative view, it highlights the strategic role of Malthusian ideas in the defence of capitalist political economy when confronted by struggles for equality and human progress. The leading historical example the author takes offers a major reassessment of the origins of the Irish Famine. His contemporary case study focuses on the Green Revolution, which the author analyses in terms of a broad Western strategy of capitalist agricultural development in the face of peasant insurgency. He examines how Malthusian arguments portrayed agricultural modernization as a humanitarian attempt to forestall a food crisis in the developing world when, in reality, he argues the agenda was to defer land reform and bolster existing rural class structures. Finally, the book examines how the political economy of underdevelopment is currently being obscured by alarm over the environmental impact of over-population, and how such Malthusian concerns represent the poor, not as victims of capitalist development, but as perpetrators of environmental destruction.

Fertility Behaviour: Population and Society in a Rajasthan

Wars and Population

ISBN: , SKU: , AUTHOR: Urlanis, B., PUBLISHER: University Press of the Pacific, Originally published in the Soviet Union in , this work covers battle losses, non-battle losses, total war losses, and the influence of wars on population dynamics.

Sweden’s and France’s pro-natalist programs,which have s

Feeding a World Population of More than Eight Billion

Feeding a World Population of More than Eight Billion People: A Challenge to Science: Since the s, breakthroughs in agriculture have made it possible to satisfy the world's increasing requirements for food. Can this trend continue over the next thirty years when the world population is projected to exceed eight billion This book takes a critical look at the immediate challenges for feeding the population just a generation from now. Based on the 10th International Symposium sponsored by the Nutrition Committee and the Trustees of the Rank Prize Funds, the volume examines the full range of related issues, from food economics to resource allocation and crop yields. Beginning with an analysis of future food needs, the articles cover basic resources and constraints, applications of science to increase yield, the role of animal products in feeding eight billion people, and diverse social issues. The book provides insights into some of the most important questions we will be faced with in the coming years, making it an invaluable resource for a wide range of researchers in agriculture, the environment, and public policy.
