Available in PDF, EPUB and Kindle. Book excerpt: Life histories can be defined as the means by which individuals (or more precisely genotypes) vary their age- or stage-specific expenditures of reproductive effort in response to genetic, phenotypic, and environmental correlates of survival and fecundity. Life histories reflect the expression of traits most closely related to individual fitness, such as age and size at maturity, number and size of offspring, and the timing of the expression of those traits throughout an individual's life. In addition to addressing questions of fundamental importance to ecology and evolution, life-history research plays an integral role in species conservation and management. This accessible primer encompasses the basic concepts, theories, and applied elements of life history evolution, including patterns of trait variability, underlying mechanisms of plastic/evolutionary change, and the practical utility of life-history traits as metrics of species/population recovery, sustainable exploitation, and risk of extinction. Empirical examples are drawn from the entire spectrum of life. A Primer of Life Histories is designed for readers from a broad range of academic backgrounds and experience including graduate students and researchers of ecology and evolutionary biology. It will also be useful to a more applied audience of academic/government researchers in fields such as wildlife biology, conservation biology, fisheries science, and the environmental sciences.

Book excerpt: Drafting a Conservation Blueprint lays out for the first time in book form a step-by-step planning process for conserving the biological diversity of entire regions. In an engaging and accessible style, the author explains how to develop a regional conservation plan and offers experience-based guidance that brings together relevant information from the fields of ecology, conservation biology, planning, and policy. Individual chapters outline and discuss the main steps of the planning process, including: • an overview of the planning framework • selecting conservation targets and setting goals • assessing existing conservation areas and filling information gaps • assessing population viability and ecological integrity • selecting and designing a portfolio of conservation areas • assessing threats and setting priorities A concluding section offers advice on turning conservation plans into action, along with specific examples from around the world. The book brings together a wide range of information about conservation planning that is grounded in both a strong scientific foundation and in the realities of implementation.
Download or read book Endocrine Disruption in Fish written by David E. Kime and published by Springer Science & Business Media. This book was released on 1998-10-31 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last half-century has shown a dramatic increase in the standard of living of millions of people in Europe, North America and many parts of the Third World. This has, in many ways been brought about by scientific and technical developments which were initiated in the 1940s and 1950s. Promises were then made that nuclear energy would provide electricity so cheap that it would not need metering, pesticides would end malnutrition throughout the world and plastics and other synthetic chemicals would revolutionise our manufacturing industry and our way of life. Whilst some of these promises have been fulfilled, the problems of long-term health risks to humans and wildlife arising from the use, production and disposal of these products were either unknown or deliberately understated. Nuclear power is rendered economically unviable when the real cost of decommissioning and storage of waste for several millenia is included, and the effects on health of both humans and wildlife of early pest eradication programmes with organochlorine pesticides were well documented in Rachel Carson's "Silent Spring". Evidence of the effects of aerosols and refrigerants on depletion of the ozone layer has led to restriction on the use of CFCs, and there is now increasing evidence of climate change resulting from our profligate use of fossil fuels.
