Allee effects are (broadly) defined as a decline in individual fitness at low population size or density. They can result in critical population thresholds below which populations crash to extinction. As such, they are very relevant to many conservation programmes, where scientists and managers are often working with populations that have been reduced to low densities or small numbers. There are a variety of mechanisms that can create Allee effects including mating systems, predation, environmental modification, and social interactions. The abrupt and unpredicted collapses of many exploited populations is just one illustration of the need to bring Allee effects to the forefront of conservation and management strategies.
Allee Effects in Ecology and Conservation provides a concise yet authoritative overview of the topic, collating and integrating a widely dispersed literature from various fields - marine and terrestrial, plant and animal, theoretical and empirical, academic and applied. This accessible text, with its clear and simple explanations of both empirical observations and theoretical predications is particularly suitable for professional and academic ecologists requiring an overview of the state-of-the-art in Allee effect research, as well as for graduate students in population ecology and conservation biology. It will also be of relevance to a wide readership of professionals in conservation and management requiring a concise summary of the topic.

This book stresses the complexity of the relationship between economic and population growth, instead of concentrating on demographic growth. Therefore it assesses its implications for the future economic, social and political advancement of those developing countries and makes certain recommendations regarding formulation and research needs in that area.

This volume explores the distribution of the rural population in Palestine from the late Ottoman period (1870-1917) to the British Mandate period (1917-1948). The book focuses on demography, specifically migrations, population size, density, growth, and the pattern of distribution in rural Palestine before the inception of Jewish settlement (1882). Grossman traces little-known Muslim ethnic groups who settled in Palestine's rural areas, primarily Egyptians, but also Algerians, Bosnians, and Circassians. The author argues that the Arab population in the zones occupied by Jews after 1882 was about one-third that of the Arab core areas; in the period studied, the decline in per-capita rural Arab farmland was mainly due to overall population growth, not displacement of Arabs; economic development suffered largely because of violent disturbances and natural disasters; the pattern of growth of Egyptian and other Muslim groups was similar to that of the Jews. The main conclusions of this study note that the size of the rural Arab population in the zones occupied by Jews after 1882 was about one-tenth of that which occupied the Arab core zones; most Egyptian settlement areas coincided with those of the Jewish zones; between 1870 and 1945, the decline of Arab farmland was mainly due to Arab population growth rather than Jewish land acquisitions; and most migrants (Jewish and Muslim) settlement zones were leftovers characterized by some form of resource disability.

Examining the nature of Third World development, its link with population movements and the regional change, and the importance of "place" within these processes, the perspectives of "Place, Migration, and Development in the Third World" offer an alternative to conventional thinking. Although development has been the subject of academic study for more than three decades, established conceptualizations are often unsuitable for understanding the process at local level. This book attempts to work from locales outwards rather than beginning by imposing generalizations upon them. This puts a high premium on knowledge of the area being studied but without this the study of development is hamstrung - place should be a touchstone against which academic findings ring true. Focusing on how population movements affect development and examining the role of place characteristics within this, this analysis emphasizes how world economic and political conditions, donor nation actions, and the policies of the Third World governments themselves are articulated at the local level.

"Land Settlement Policies and Population Redistribution in Developing Countries" provides a comparative analysis, initiated by the International Labour Office, of land settlement policies and programs in developing countries under various socioeconomic conditions. It reports the findings of nine case studies conducted in countries which have established resettlement schemes. The major focus of the studies is the identification of the factors that have contributed to the success or failure of resettlement schemes from the point of view of the populations concerned--in relation to the original objectives of the policymakers--and with respect to development objectives other than population distribution.

This book examines potential economic opportunities that countries can experience when fertility rates fall and the average life expectancy of the working age population increases. It presents detailed demographic and economic analysis of middle-income countries throughout the world in order to show how these countries can take advantage of this demographic bonus. The book first traces the common link between policies that contribute to fertility transition as well as create the right kind of environment for reaping the benefit of demographic dividend. Next, it explores different countries and regions who are at different levels of development. It assesses the long term impact of gender equality on economic growth and development in Latin America; describes the life-cycle saving patterns of Mexican households; and examines demographic determinants of economic growth in BRICS. The book also offers demographic and economic analysis of the Mediterranean area, Sub-Saharan Africa, and New Zealand. The comparison between the different territorial contexts allow for the identification of three typologies of demographic dividend: the first dividend, when the working population grows faster than total population, the second dividend, as active generations get older and invest their savings in the production system of their country, and the third dividend, based on the coexistence of two populations age structure strongly contrasting. Overall, this book argues for the need to capitalize on the opportunities that come from the demographic dividend by investing heavily in education programs, training programs for the population working age, health programs, the creation of health insurance systems as well as programs to reduce or increase fertility levels.

Based on an intensive fieldwork in a southern Hebei village in northern China (1992/3), the author takes an institutional approach and focuses on the way deliberate Chinese state policies driven by new economic and social agendas since the late 1970s have impacted on marriage, family relations and consequently on the way fertility trends have been adversely affected; the study is also very much concerned with the human dimension and the way in which such social and economic changes are perceived and applied in a rural community. The research presented in this study goes a long way to unravelling the puzzle concerning the reasons for a very rapid decline in Chinese fertility rates, contrasting sharply with a very different fertility transition within western cultures.

Although health equity and diversity-focussed research has begun to gain momentum, there is still a paucity of research from health geographers that explicitly explores how geographic factors, such as place, space, scale, community, and location, inform multiple axes of difference. Such axes can include residential location, age, sex, gender, race/ethnicity, culture, religion, socio-economic status, marital status, sexual orientation, education level, and immigration status. Specifically focussing on Canada's rapidly changing society, which is becoming increasingly pluralized and diverse, this book examines the place-health-diversity intersection in this national context. Health geographers are well positioned to offer a valuable contribution to diversity-focussed research because place is inextricably linked to differential experiences of health. For example, access to health care and health promoting services and resources is largely influenced by where one is physically and socially situated within the web of diversity. Furthermore, applying geographic concepts like place, in both the physical and social sense, allows researchers to explore multiple axes of difference simultaneously. Such geographic perspectives, as presented in this book, offer new insights into what makes diverse people, in diverse places, with access to diverse resources (un)healthy in different ways in Canada and beyond.

This book offers an in-depth African perspective to the major issues in demographic discourse in sub-Saharan Africa. It provides comprehensive analysis of sub-Saharan African censuses, profiling demographic changes, trends, patterns and consequences in the region. Interdisciplinary, comprehensive, accessible, simple and topical, this volume is perfectly suited to researchers, students and lecturers who are interested in understanding sub-Saharan African population dynamics and issues.

This balanced text offers a concise and readable introduction to world population growth and its implications for the future. With a population currently exceeding six billion and expected to reach ten billion by mid-century, the globe faces a demographic situation that is now more critical than ever before. While the developed world grapples with the problems of an aging and declining population, the developing world will contend with the opposite dilemma of explosive growth. And so the strongest factors shaping the global environment in the decades to come will include population fertility, the social and economic impact of the HIV/AIDS epidemic, legal and illegal immigration, and refugees. The implications are enormous as population growth exacerbates food and resource scarcities, places pressure on institutions, and promotes the potential for conflict. Drawing on a geographical perspective and using examples from around the world, this fully updated edition will be an invaluable resource for all readers concerned with the intertwined issues of population, environment, and health.

Hip-Hop and Dismantling the School-to-Prison Pipeline was created for K-12 students in hopes that they find tangible strategies for creating affirming communities where students, parents, advocates and community members collaborate to compose liberating and just frameworks that effectively define the school-to-prison pipeline and identify the nefarious ways it adversely affects their lives. This book is for educators, activists, community organizers, teachers, scholars, politicians, and administrators who we hope will join us in challenging the predominant preconceived notion held by many educators that Hip-Hop has no redeemable value. Lastly, the authors/editors argue against the understanding of Hip-Hop studies as primarily an academic endeavor situated solely in the academy. They understand the fact that people on streets, blocks, avenues, have been living and theorizing about Hip-Hop since its inception. This important critical book is an honest, thorough, powerful, and robust examination of the ingenious and inventive ways people who have an allegiance to Hip-Hop work tirelessly, in various capacities, to dismantle the school-to-prison pipeline.

The Politics of Identity in Latin American Censuses contributes new and original perspectives to existing discussions about the shaping of multiculturalist ideology in Latin America, its interweaving with the cultural politics of neoliberalism and the relation between ethnic identification resurgence and economic globalization. Scrutinising national censuses across the continent, the studies included in this volume reveal clear relationships between censuses, nation-building and government projects, but also strong and determinant connections between domestic and supra-national spheres. The contributors to this volume open provocative avenues of research on Latin American societies by demonstrating how, in the realm of identity politics, supra-national institutions and normativity socialise national census bureaus in a way that largely annuls ideological differences between regional governments. This book was originally published as a special issue of the Journal of Iberian and Latin American Research.

There is general consensus among the international population community that the commitment achieved at the International Conference on Population and Development (Cairo, 1994) to womens empowerment, along with the related goals of improving womens reproductive health and securing their reproductive rights, represented a paradigm shift in the discourse about population and development, even though there are differences in view whether this is a positive change or not. But while the rhetoric about womens empowerment is pervasive, the concept remains ill-defined, and its relationship to demographic processes has not been well articulated, either theoretically or empirically. This book brings together leading researchers and policy advocates to explore whether the concept of womens empowerment is indeed useful for an understanding of key demographic processes. Its contributors identify new directions for demographic research from the analysis of available data that measure womens empowerment, and point to the implications for population-related policies. Demographic research has focused relatively little to date on gender, let alone the question of power. Yet critiques of available data argue that traditional womens-status indicators, such as education and employment, are often not sensitive enough to capture the nuances of gender power relations and the ways in which they govern womens and mens reproductive behaviour. This book moves forward to the complex task of conceptualizing, measuring, and analysing womens empowerment. In laying this groundwork, it provides critically important insights into the causes and consequences of population change, including migration. The book combines conceptual and empirical research with policy directions and considers the relevance of economic, social, and cultural contexts for the health and well-being of women, adolescents, and children. The countries under study are of both the North and the South. This book represents state-of-the-art knowledge on the two-way linkages between womens empowerment and demographic processes.

Are poverty, misery, famine, disease and war inevitably part of the human condition? Will the creations of science become uncontrollable and socially dangerous, like Frankenstein's monster? Or can science and education create a world of material plenty - a war-free world, where the benevolent, creative and intellectual sides of human nature will have a chance to flourish?

There is little question that issues arising from the interrelationships among resources, the environment, population growth, and Third World development are of concern to the whole world. This book is a complete guide for students, researchers, and policymakers to current issues, trends, and strategies and prospects for the future. Demographic data, development policy and strategies, and theory are discussed for the Third World in general as well as for specific countries and regions.

Poverty is generally defined as a lack of material resources. However, the relationships that poor people have with their possessions are not just about deprivation. Material things play a positive role in the lives of poor people: they help people to build social relationships, address inequalities, and fulfill emotional needs. In Materializing Poverty, anthropologist Erin Taylor explores how residents of a squatter settlement in Santo Domingo, Dominican Republic, use their material resources creatively to solve everyday problems and, over a few decades, radically transform the community. Their struggles show how these everyday engagements with materiality, rather than more dramatic efforts, generate social change and build futures.

Today's demographic struggle for power translates itself into an inter-ethnic war of numbers. The goal of this war of numbers is to increase the economic and political power of an ethnic group relative to other groups, and the method by which this is achieved entails the increase in size of one population relative to others. In describing this struggle, the book asks - and answers - three questions: What is it that ethnic groups think they can achieve by augmenting their numbers? By what methods do leaders of ethnic groups actually manipulate demographic characteristics in their struggle for power? How can such demographic struggles for power be avoided and thus potentially explosive inter-ethnic conflicts diffused?
This book offers suggestions for structural alterations within states that will sever the link between ethnic size and power, and thus eliminate the rationale for the demographic struggle for power.

This monograph discusses Portuguese eugenics within a strong international historiographical comparative framework and situates it within different regional, scientific and ideological types of eugenics in the same period. The author argues about three factors that curtailed the development of eugenics in Portugal: the low level of institutionalization, Catholic opposition and the conservative nature of the Salazar regime. The eugenic science and movement was confined to three principal expressions: individualized studies on mental health, often from a 'biotypological' perspective; a particular stance on racial miscegenation within the context of the existence of large colonies under Portuguese rule; and a diffuse model of social hygiene, maternity care and puericulture. This book not only brings to light an unstudied eugenics movement; it also invites the reader to re-think the relations between northern and southern forms of eugenics, the role of religion, the dynamic nature of eugenics in finding a home for its theories and the nature of colonialism.

As one of South America's larger capital cities, Lima, Peru, is remarkably understudied as a demographic and economic entity unto itself. In this important book, Henry Dietz presents an in-depth historical, sociological, and political analysis of a major Latin American city in the post-World War II period. Dietz examines electoral data for Lima's districts from six censuses conducted between 1940 and 2007, framed against a backdrop of extensive demographic data for the city, to trace the impact of economic collapse and extended insurgency on Lima and its voters. Urbanization in Lima since World War II has at times been rapid, violent, and traumatic, and has resulted in marked social inequalities. Dietz looks at how equity across the city has not in general improved; Lima is today segregated both spatially and socially. Dietz asks if and how a high degree of segregation manifests itself politically as well as socially and spatially. Do urban dwellers living under profound and enduring social segregation consistently support different parties and candidates? As institutional political parties have faded since the 1990s and have been replaced by personalist movements, candidacies, and governments, Dietz explores how voters of different social classes behave. The result is a vital resource for researchers seeking well-contextualized information on elections and economics in Peru. This book will be of interest to scholars of politics or economics, especially in Latin America, but also to a much wider audience interested in how the developments in Lima, Peru, affect the global sociopolitical climate.

This book explores social factors such as culture, mass media, political systems, and migration that influence public health while systematically considering how we may best study these factors and use our knowledge from this study to guide public health interventions. Throughout, contributors emphasize the potential of population strategies to influence traditional risk factors associated with health and disease. Each section ends with Galea 's integrative chapters, bringing the observations and conclusions from the chapters into clear, usable focus.

Connecting seemingly unrelated instances of essential worker shortages around the world, investment analyst Shamil Ismail builds a compelling and well-researched narrative explaining why aging populations and falling birth rates are leading to a shrinking pool of essential workers in developed countries, which could massively disrupt their societies.

Methodically unpacking the factors driving this escalating crisis, he shows why proposed solutions such as automation, AI, and raising the retirement age will not fix the problem. The implications will be widespread, leading to crumbling cities with decaying infrastructure, while economic growth will be stunted by creaking supply chains, declining demand, and a shrinking tax base.

Sifting through the data, trends and forecasts, Ismail answers these intriguing questions, allowing us to prepare for the daunting future that lies ahead.

• When are we likely to see the first major signs of this new reality?
• Which countries will be most impacted, and by when?
• How will companies and investment markets be affected?
• Can this path to decay be avoided and what can we do?

The Age of Decay is a provocative read that will stimulate debate over the impact of the shifting demographics on society. It is an indispensable factor in strategic planning for business leaders, investors and governments. Tautly written with the clever use of occasional fictional narratives, the book distils a wide range of topics into a riveting read.

A must-read for anyone interested in how the future could unfold.

Most advanced democracies are currently experiencing accelerated population ageing, which fundamentally changes not just their demographic composition; it can also be expected to have far-reaching political and policy consequences. This volume brings together an expert set of scholars from Europe and North America to investigate generational politics and public policies within an approach explicitly focusing on comparative political science. This theoretically unified text examines changing electoral policy demands due to demographic ageing, and features analysis of USA, UK, Japan, Germany, Italy and all major EU countries. As the first sustained political science analysis of population ageing, this monograph examines both sides of the debate. It examines the actions of the state against the interests of a growing elderly voting bloc to safeguard fiscal viability, and looks at highly-topical responses such as pension cuts and increasing retirement age. It also examines the rise of 'grey parties', and asks what, if anything, makes such pensioner parties persist over time, in the first ever analysis of the emergence of pensioner parties in Europe. Ageing Populations in Post-Industrial Democracies will be of interest to students and scholars of European politics, and to those studying electoral and social policy reform. Official publication date 1st January 2012.

Wide-Ranging Coverage of Parametric Modeling in Linear and Nonlinear Mixed Effects Models
Mixed Effects Models for the Population Approach: Models, Tasks, Methods and Tools presents a rigorous framework for describing, implementing, and using mixed effects models. With these models, readers can perform parameter estimation and modeling across a whole population of individuals at the same time.

Easy-to-Use Techniques and Tools for Real-World Data Modeling
The book first shows how the framework allows model representation for different data types, including continuous, categorical, count, and time-to-event data. This leads to the use of generic methods, such as the stochastic approximation of the EM algorithm (SAEM), for modeling these diverse data types. The book also covers other essential methods, including Markov chain Monte Carlo (MCMC) and importance sampling techniques. The author uses publicly available software tools to illustrate modeling tasks. Methods are implemented in Monolix, and models are visually explored using Mlxplore and simulated using Simulx.

Careful Balance of Mathematical Representation and Practical Implementation
This book takes readers through the whole modeling process, from defining/creating a parametric model to performing tasks on the model using various mathematical methods. Statisticians and mathematicians will appreciate the rigorous representation of the models and theoretical properties of the methods while modelers will welcome the practical capabilities of the tools. The book is also useful for training and teaching in any field where population modeling occurs.
