The study of nature is a complex science involving many different fields from geology and meteorology to biology, zoology, and botany. This complexity indicates nature's broad scope of impact. It is at once beautiful and dangerous, displaying power beyond human control. An understanding of the basic principles and concepts of the study of nature is therefore both enriching and practical. In The Handbook of Nature, authors Frank R. Spellman and Joni Price-Bayer provide a comprehensive guide to the study of nature in terms the layperson can grasp easily. This accessible reference work is for the non-specialist looking for quick, accurate information on all aspects of the study of nature. The handbook is arranged thematically for a logical and user-friendly progression through the material. It includes chapters on the earth's structure and landforms, the atmosphere and weather, water and water sources, and the many different forms of life from single-celled organisms to complex vertebrates. Along with basic natural scientific principles, the authors look closely at the consequences of human interactions with the environment we inhabit. This reference concludes with a glossary and index, and each chapter provides further resources and recommended reading. It is an essential tool for students and professionals alike.

This book will enable the identification of each of the 57 species of butterfly that has been recorded from the Cayman Islands. There is a description of every butterfly, stressing its most important characteristics, with photographs of living and mounted specimens. The distribution, history and biology of each species are reviewed and the plants which provide adult butterflies with nectar or feed their caterpillars are tabulated. A general introduction includes a discussion of the affinities and size of the Caymanian butterfly fauna. The three islands share most of their butterfly species but each island has uniquely characteristic elements and five subspecies live only in the Cayman Islands. Knowledge is fundamental to conservation; it is hoped that both the casual butterfly watcher and those more committed to the study of butterflies will discover much of interest in this book and thereby make a contribution to the continuing survival of these beautiful insects.

One family of viruses is responsible for the infection of many species of vertebrates. These are the retroviruses whose genomic RNA is used to support genetic information and ensures many essential functions that are required for the formation of an infectious viral particle. These functions depend on structures formed by the folding of the genomic RNA. Structures and Functions of Retroviral RNAs describes the formation of these structures and their specific interactions with nucleic acids and proteins. In light of recent advances in molecular virology, it provides an understanding of the various facets of the retroviral genome. It emphasizes in particular that the study of the structure-function relationship of retroviral RNAs is a driving force behind increased research into HIV-1, the main causal agent of AIDS. Indeed, one of the challenges of pharmacology lies in the exploitation of several targets which allow us to anticipate and stem the emergence of resistance to anti-HIV drugs. The book also presents structures and interactions that may be potential future targets in this regard.

In the post-genome era, questions concerning gene products, enzymes, and metabolism are returning to the forefront of life science research. Genetic information on its own does not fully account for an enzyme's kinetic and regulatory properties or for the behavior of the enzymes within its particular cellular milieu. Unanswered questions about the regulation, integration, and adaptation of metabolism have led to a resurgence of interest in protein, enzymological, and metabolic research for understanding biological processes.

Functional Metabolism: Regulation and Adaptation provides a comprehensive survey of metabolism. It includes an in-depth examination of the regulation of carbohydrates, lipids, and amino acids, and approaches to the study of enzyme regulation, signal transduction, and control of transcription and translation. The contributors-an internationally recognized group of researchers-also cover:

• The metabolic basis of diabetes, obesity, and blood disorders
• Oxidative stress and antioxidant defenses in health and disease
• Novel perspectives on biochemical adaptation to environmental stress
• Application of metabolic knowledge to developments in organ preservation and understanding the origin of life

From the basics of metabolic regulation and adaptation to the latest relevant advances in the genetic, proteomic, and enzymatic basis of how cells regulate their functions, Functional Metabolism: Regulation and Adaptation offers the most exhaustive treatment of the subject currently available. It is an essential text for students and practitioners in biochemistry, cell and molecular biology, and biomedicine.
