Book Description
There are many different types of organisms in the world: they differ in size, physiology, appearance, and life history. The challenge for evolutionary biology is to explain how such diversity arises. The Evolution of Life Histories does this by showing that natural selection is the principal underlying force molding life history variation. The book describes in particular the ways in which variation can be analyzed and predicted. It covers both the genetic and optimization approaches to life history analysis and gives an overview of the general framework of life history theory and the mathematical tools by which predictions can be made and tested. Factors affecting the age schedule of birth and death and the costs of reproduction are discussed. The Evolution of Life Histories concentrates on those theoretical developments that have been tested experimentally. It will interest both students and professionals in evolution, evolutionary ecology, mathematical and theoretical biology, and zoology and entomology.

Book Description
The floral industry represents a significant proportion of agricultural income in several developed countries, particularly the USA, the Netherlands and Japan. Hitherto, the sheer diversity of flower seeds, in their form, function and biology, has hindered the production of a comprehensive treatment of the topic. This book provides a unique and much-needed resource of information on the biology and technology of flower seeds. It presents in-depth information on the history and evolution of the ornamental and wild flower seed industries followed by recommendations for successful breed and production programs. A comprehensive coverage of the biology of flower seeds is considered as well as appropriate technologies associated with germination, vigor and viability testing. In this volume, the first of its kind, international authorities from academia and industry have been brought together to provide a comprehensive reference resource for both practitioners and students of seed science and technology and of ornamental horticulture.

Book Description
The second edition of this book is created to assist the clinician in the initial response to the needs of a child or adult exposed to a poisonous or injurious plant. It lists common plants that might lead to the development of the symptom complex and describes the mechanisms of action of the implicated toxin, additional clinical manifestations, and specific therapeutics for each presentation. It has methodically enhanced the previous edition’s botanical rigor with insights from both pharmacognosy and clinical medicine to make it a truly comprehensive source for anyone who has an interest in plants.

Book Description
This encyclopedic reference work on pharmacognosy covers the study of those natural substances, principally plants, that find a use in medicine. Its popularity and longevity stem from the book's balance between classical (crude and powdered drugs' characterization and examination) and modern (phytochemistry and pharmacology) aspects of this branch of science, as well as the editor's recognition in recent years of the growing importance of complementary medicines, including herbal, homeopathic and aromatherapy. No other book provides such a wealth of detail. A reservoir of knowledge in a field where there is a resurgence of interest - plants as a source of drugs are of growing interest both in complementary medicine fields and in the pharmaceutical industry in their search for new 'lead compounds'. Dr Evans has been associated with the book for over 20 years and is a recognised authority in all parts of the world where pharmacognosy is studied, his knowledge and grasp of the subject matter is unique. Meticulously referenced and kept up to date by the editor, new contributors brought in to cover new areas. New chapter on 'Neuroceuticals'. Addition of many new compounds recently added to British Pharmacopoeia as a result of European harmonisation. Considers development in legal control and standardisation of plant materials previously regarded as 'herbal medicines'. More on the study of safety and efficacy of Chinese and Asian drugs. Quality control issues updated in line with latest guidelines (BP 2007).

Book Description
This volume focuses on the importance of therapeutically active compounds of natural origin. Natural materials from plants, microbes, animals, marine organisms and minerals are important sources of modern drugs. Beginning with two chapters on the development and definition of the interdisciplinary field of pharmacognosy, the volume offers up-to-date information on natural and biosynthetic sources of drugs, classification of crude drugs, pharmacognosical botany, examples of medical application, WHO ́s guidelines and intellectual property rights for herbal products.
