Book Description
Population Geography, Second Edition focuses on the relationships between population distribution and environment. This book aims to introduce population study, explain the geographical approach, and suggest a frame on which to hang regional studies of population. This edition begins by defining population geography, followed by a discussion on the types and problems of data and world distribution of population. The measures of population density and distribution, urban and rural populations, patterns of fertility and mortality, and migrations are elaborated. The patterns of population composition that includes age-structure, sex-composition, marital status, families and households, economic composition, nationality, language, religion, and ethnic composition are also considered. This text concludes with a discussion on population growth and resources. This publication is intended as an introduction to population study for geographers.

Book Description
Andrei Rogers, one of the world's leading authorities on population trends, offers a powerful technique for carrying out regional population projections. He gives a clear step-by-step analysis and demonstrations of actual projections of future populations at the regional level. The examples show how to calculate regional population growth rates, age compositions, and spatial distributions using data from several developed and less developed countries.

Book Description
This book studies the origins and development of population geography as a discipline. It explores the key concepts, tools and statistical and demographic techniques that are widely employed in the analysis of population. The chapters in this book: Provide a comprehensive geographical account of population attributes in the world, with a particular focus on India; Study the three major components of population change – fertility, mortality and migration – that have remained somewhat neglected in the study of human geography so far; Examine the salient social, demographic and economic characteristics of population, along with topics such as size, distribution and growth of population; Discuss major population theories, policies and population–development–environment interrelations, thus marking a significant departure from the traditional pattern-oriented approach. Well supplemented with figures, maps and tables, this key text will be an indispensable read for students, researchers and teachers of human geography, demography, anthropology, sociology, economics and population studies.

Book Description
Like the original two-volume work, this work attempts to present a systematic and comprehensive exposition, with illustrations, of the methods used by technicians and research workers in dealing with demographic data. The book is concerned with how data on population are gathered, classified, and treated to produce tabulations and various summarizing measures that reveal the significant aspects of the composition and dynamics of populations. It sets forth the sources, limitations, underlying definitions, and bases of classification, as well as the techniques and methods that have been developed for summarizing and analyzing the data.

Book Description
Bamboos constitute one of a few select categories of plants which are taxonomically related, very rich in species and of vital economic and ecological importance. Since the early 20th century the accepted number of species of bamboos, world wide, has tripled. However, until now information was scattered through numerous, often not easily available publications.The Bamboos of the World, is the first comprehensive (taxonomic as well as horticultural) reference work that provides basic information on bamboos world wide, whether they are wild or cultivated, well-known or rather unknown. The work, based on bamboo literature, facilitates access to further data by citation and a comprehensive bibliography. Among the main data included are botanical names with synonyms, and geographical distribution of genera and species, varieties with their distinctive characters, common bamboo names, plant introductions to the West, plant size and uses. The distribution of genera is mapped.The Bamboos of the World presents a wealth of essential information in an accessible and structured manner. It gives the opportunity to check under what names, and where, relevant information on any bamboo can be found. For the researcher with management and development interests it provides a convenient means of basing bamboo resource on a sound understanding of generic and species relationships, with names that appear in earlier literature put into context. The work should prove to be invaluable for those interested in the morphology, taxonomy, distribution and cultivation of bamboos. It should support botanical, forestry, horticultural and ecological research, training and resource management.

Book Description
This compact and accessible text provides a comprehensive, issue-oriented introduction to population geography. First grounding students in the fundamentals, Bruce Newbold then explains the tools and techniques commonly used to describe and understand population concepts using real-world issues and events. Drawing on both U.S. and international cases, he explores such pressing concerns as HIV/AIDS, international migration, refugee movements, fertility, mortality, resource scarcity, and conflict. Every chapter includes both methods and focus sections to provide a more in-depth discussion of the ideas and concepts developed in the book. In addition, a wide array of maps, tables, and figures illustrate and enhance the cases. Newbold highlights the geographical perspective—with its ability to provide powerful insights and bridge disparate issues—by emphasizing the roles of space and place, location, regional differences, and diffusion. Arguing that an understanding of population is essential to prepare for the future, this cogent text will provide upper-division undergraduates with a thorough grasp of the field.

Book Description
In 1950 men and women in the United States had a combined life expectancy of 68.9 years, the 12th highest life expectancy at birth in the world. Today, life expectancy is up to 79.2 years, yet the country is now 28th on the list, behind the United Kingdom, Korea, Canada, and France, among others. The United States does have higher rates of infant mortality and violent deaths than in other developed countries, but these factors do not fully account for the country's relatively poor ranking in life expectancy. International Differences in Mortality at Older Ages: Dimensions and Sources examines patterns in international differences in life expectancy above age 50 and assesses the evidence and arguments that have been advanced to explain the poor position of the United States relative to other countries. The papers in this deeply researched volume identify gaps in measurement, data, theory, and research design and pinpoint areas for future high-priority research in this area. In addition to examining the differences in mortality around the world, the papers in International Differences in Mortality at Older Ages look at health factors and life-style choices commonly believed to contribute to the observed international differences in life expectancy. They also identify strategic opportunities for health-related interventions. This book offers a wide variety of disciplinary and scholarly perspectives to the study of mortality, and it offers in-depth analyses that can serve health professionals, policy makers, statisticians, and researchers.

Book Description
Coevolution—reciprocal evolutionary change in interacting species driven by natural selection—is one of the most important ecological and genetic processes organizing the earth's biodiversity: most plants and animals require coevolved interactions with other species to survive and reproduce. The Geographic Mosaic of Coevolution analyzes how the biology of species provides the raw material for long-term coevolution, evaluates how local coadaptation forms the basic module of coevolutionary change, and explores how the coevolutionary process reshapes locally coevolving interactions across the earth's constantly changing landscapes. Picking up where his influential The Coevolutionary Process left off, John N. Thompsonsynthesizes the state of a rapidly developing science that integrates approaches from evolutionary ecology, population genetics, phylogeography, systematics, evolutionary biochemistry and physiology, and molecular biology. Using models, data, and hypotheses to develop a complete conceptual framework, Thompson also draws on examples from a wide range of taxa and environments, illustrating the expanding breadth and depth of research in coevolutionary biology.
