  • Focusing on the rich biodiversity of Costa Rica, the contributors demonstrate the use of geographic information systems (GIS) to enhance conservation efforts. They give an overview of the spatial nature of conservation and management and the current status of digital mapping in Costa Rica; a review of the basic principles behind digital mapping technologies; a series of case studies using these technologies at a variety of scales and for a range of conservation and management activities; and the results of the Costa Rican gap analysis project....

  • The science of conserving artworks and other items of cultural significance has undergone considerable change since 1982 when this series was instigated, mostly involving the development or application of new materials or techniques. Their understanding by conservators, restorers and students continues, nonetheless, to depend on familiarity with the underlying scientific principles which do not change and which are clearly explained in these books.

  • Transgenic Mice as Models of Genetic Disease Several organisms have been studied extensively as genetic models, including Mus musculus (mouse), Drosophila melanogaster (fruit fly), Caenorhabditis elegans (nematode), Saccharomyces cerevisiae (baker's yeast), and Escherichia coli (colonic bacterium). The ability to use these evolutionarily distant organisms as genetic models that are relevant to human physiology reflects a surprising conservation of genetic pathways and gene function.

  • Chapter 15 - Natural resource and energy economics. After studying this chapter you will be able to understand: Explain why falling birthrates mean that we are not likely to run out of natural resources, describe why using a mix of energy sources is efficient, even if some of them are quite costly, discuss why running out of oil would not mean running out of energy, show how the profit motive can encourage resource conservation, relate how to use property rights to prevent deforestation and species extinction.

  • The purpose of this text is to provide the basis for an upper-level undergraduate or graduate course over one or two semesters, covering basic concepts and examples of fluid mechanics with particular applications in the natural environment. The book is designed to meet a dual purpose, providing an advanced fundamental background in the fluid mechanics of environmental systems and also applying fluid mechanics principles to a variety of environmental issues.

  • The second section of the book involves the regional biogeography of individual taxa. This section begins with a chapter by Alberto Taylor and his colleagues on the biogeography of cycads in Central America. Their natural history and experimental ecological methods integrate the evolutionary context of the cycad lineage with contemporary autecology, and they elucidate biogeographic patterns and conservation priorities, the latter of which are under-appreciated but pressingly important in Central America.

  • Because American ecocriticism, as a movement, is only about a dozen years old, generalizations about it are hard to make and still harder to validate.1 So I want to begin, not by describing the principles and practices of ecocriticism in any detail (in fact, that is something I want to delay, especially as regards the practices, until chapter four), but by looking at what seems to be, for many of its adherents, ecocriticism’s moment of origin, which is threefold in its implications.

  • Conserving Living Natural Resources provides students, managers, and general readers with an introduction to the principles of managing biological resources. It presents the historical and conceptual contexts of three seminal approaches to the management of living natural resources: utilitarian management for harvest of featured species and control of unwanted species, protection and restoration of populations and habitats to maintain biodiversity, and management of complex ecosystems to sustain both productivity and biodiversity.

  • There is a basic law in thermodynamics; the law of conservation of energy, which states that energy may neither be created nor destroyed just can be transformed. Nature is an expert using this physics fundamental law favouring life and evolution of species all around the planet, it can be said that we are accustomed to live under this law that we do not pay attention to its existence and how it influence our lives.

  • I have tried to write a non-technical tour through the principles of physics. The theme running through this tour is that progress has often consisted in uncovering “hidden unities”. Let me explain what I mean by this phrase, taking the example (from Chapter 3) of electricity and magnetism. The unity here is hidden, because at first sight there seemed to be no connection between the two.

  • The quality of dialogue with partner countries (government and civil society representatives) is a key to establishing effective development cooperation policies and to their successful implementation. Partnership, ownership of development processes by the target population, and strengthening of institutional and administrative capacity to effectively manage change, are principles which are now largely shared by all donors. Two issues are given emphasis in the EC’s develop- ment policy in this regard, namely: Role of civil society.

  • In this introductory chapter, we indicate the aims and structure of this book. We also indicate some of the ways in which the book is not synoptic in its coverage, but rather offers an interlinked account of some major developments in our understanding of the dynamics of ecological systems, from populations to communities, along with practical applications to important problems.

  • Seismic – At the Weyburn Field, multi-component 3-D surface seismic time-lapse surveys were conducted at intervals of approximately 12 months, starting prior to the commencement of CO2 injection in 2000, and repeated in 2001 and 2002. The resultant time-lapse images (primarily seismic amplitude changes) acquired at Weyburn clearly map the spread of CO2 over time within the reservoir, fulfilling a key objective set at the outset of the project.

  • This is a short book, but it took a long time to write. In two previous books, Beyond All Reason and Desperately Seeking Certainty, we criticized some currently popular theories like originalism, the view (held by many conservative constitutional scholars) that the Constitution’s meaning is fi xed by the history of its creation. We also criticized theories of leading scholars at the other end of the ideological spectrum.
