Download or read book Volume 1 Evolution Systematics and Biogeography written by Niels P. Kristensen and published by Walter de Gruyter. This book was released on 2013-02-06 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covering 100 years of zoological research, the Handbook of Zoology represents a vast store of knowledge. Handbook of Zoology provides an in-depth treatment of the entire animal kingdom covering both invertebrates and vertebrates. It publishes comprehensive overviews on animal systematics and morphology and covers extensively further aspects like physiology, behavior, ecology and applied zoological research. Although our knowledge regarding many taxonomic groups has grown enormously over the last decades, it is still the objective of the Handbook of Zoology to be comprehensive in the sense that text and references together provide a solid basis for further research. Editors and authors seek a balance between describing species richness and diversity, explaining the importance of certain groups in a phylogenetic context and presenting a review of available knowledge and up-to-date references. New contributions to the series present the combined effort of an international team of editors and authors, entirely published in English and tailored to the needs of the international scientific community. Upcoming volumes and projects in progress include volumes on Annelida (Volumes 1-3), Bryozoa, Mammalia, Miscellaneous Invertebrates, Nannomecoptera, Neomecoptera and Strepsiptera and are followed later by fishes, reptiles and further volumes on mammals. Background The renowned German reference work Handbook of Zoology was founded in the 1920's by Professor Willi Kükenthal in Berlin and treated the complete animal kingdom from single cell organisms to mammals in eight thematic volumes: Volume I Protozoa, Porifera, Colenteratea, Mesozoa (1925); Volume II Vermes (1933/34); Volume III Arthropoda ex. Insecta (1927/1932); Volume IV Arthropoda: Insecta; Volume V Solenogastres, Mollusca, Echinoderma (1925); Volume VI Pisces / Amphibia (1930); Volume VII Reptilia / Aves (1931); Volume VIII Mammalia. The Volumes IV Arthropoda: Insecta and VII Mammalia continued publication into the present with the most recent contributions in English language. Adapting to the accelerating speed of scientific discovery in the past decades the Handbook of Zoology entered a next phase in 2010. In the new edition of the Handbook of Zoology, the original eight thematic volumes gave way for smaller and more flexible groupings that reflect the current state of phylogenetic knowledge. All subsequent volumes were published in print as well as e-book format. The Handbook of Zoology is additionally offered as a database, the Handbook of Zoology Online, which can easily be searched and rapidly updated. Original Handbook material (ca. 28 000 pages) has been reordered along taxonomic (instead of bibliographical) categories and forms the historical basis of this Online Reference Work. As a living Online Reference, the content is continuously updated and new content added. The material can be accessed through taxonomic and subject categories as well as free text, with a diversity of linking and search options. Faster publication times through online-first publication, reference- and cross-linking, and make the Handbook of Zoology highly attractive to both authors and users.

Book excerpt: The African armyworm, Spodoptera exempta (Walker) (Lepidoptera: Noctuidae is a serious migratory pest of cereal crops and grasslands. It can impact upon the livelihoods of farmers in many countries of sub-Saharan Africa, Yemen, some Pacific islands and parts of Australia. Containing as much up-to-date information as possible on the biology, ecology, epidemiology and management of this pest as well as containing an extensive list of useful references, this handbook will be of interest to those working in the agricultural sector, particularly those reponsible for the control of migrant pests.

Download or read book Insect Plant Biology written by Louis M. Schoonhoven and published by Oxford University Press. This book was released on 2005-12 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Half of all insect species are dependent on living plant tissues, consuming about 10% of plant annual production in natural habitats and an even greater percentage in agricultural systems, despite sophisticated control measures. Plants are generally remarkably well-protected against insect attack, with the result that most insects are highly specialized feeders. The mechanisms underlying plant resistance to invading herbivores on the one side, and insect food specialization on the other, are the main subjects of this book. For insects these include food-plant selection and the complex sensory processes involved, with their implications for learning and nutritional physiology, as well as the endocrinological aspects of life cycle synchronization with host plant phenology. In the case of plants exposed to insect herbivores, they include the activation of defence systems in order to minimize damage, as well as the emission of chemical signals that may attract natural enemies of the invading herbivores and may be exploited by neighbouring plants that mount defences as well." "Insect-Plant Biology discusses the operation of these mechanisms at the molecular and organismal levels, in the context of both ecological interactions and evolutionary relationships. In doing so, it uncovers the highly intricate antagonistic and mutualistic interactions that have evolved between plants and insects. The book concludes with a chapter on the application of our knowledge of insect-plant interactions to agricultural production." "This multidisciplinary approach will appeal to students in agricultural entomology, plant sciences, ecology, and indeed anyone interested in the principles underlying the relationships between the two largest groups of organisms on earth: plants and insects."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
