  • The Action of Hormones in plants and invertebrates

    • 1st Edition
    • Kenneth Thimann
    • English
    The Action of Hormones in Plants and Invertebrates focuses on the mechanisms of action of hormones in plants and invertebrates, including auxins, vitamins, steroids, and carotenoids. The book considers plant growth hormones, hormone-like substances in fungi, and hormones in insects and crustaceans. This volume is organized into four chapters and begins with a historical overview of the concept of hormones in plants, and then describes assay methods for auxins, along with auxin chemistry, transport, and role in tropisms. The discussion moves to other plant hormones such as wound hormones, flower-forming hormones, vitamins, steroids, carotenoids, rhizocaline, and caulocaline. The book then methodically explains insect hormones and their sources; the role of hormones in reproduction and postembryonic development; and hormone-induced color change in insects. This volume also offers information on the mode of action and physicochemical properties of insect hormones. The book concludes with a chapter on the biological effects of hormones on Crustacea, from sex characteristics to color change, molting and growth, retinal pigment movements, locomotion, and ovarian development. This book will be of interest to biologists, zoologists, botanists, and endocrinologists.

  • Biochemistry of the Glycosidic Linkage an Integrated View

    • 1st Edition
    • Romano Piras
    • English
    Biochemistry of the Glycosidic Linkage: An Integrated View is a collection of papers presented at The Pan-American Association of Biochemical Societies Symposium, held in San Carlos de Bariloche, Argentina on November 8-11, 1971. This symposium is organized as a tribute to Luis F. Leloir and his contributions in the field glycosidic linkage. This book is divided into six sessions encompassing 57 chapters. The opening session discusses the role of biochemical mechanisms in the glycosidic linkage formation. The following sessions examine the metabolic functions of some disaccharides, such as trehalose, sucrose, glucose, and starch. These sessions also look into the biosynthesis, function, and properties of carbohydrates containing polymers. The discussion then shifts to the control of enzyme biosynthesis involved in the glycosidic linkage metabolism, with particular emphasis on alpha-amylase, lactose synthetase, phosphorylase, and neuraminidase enzymes. Another session is devoted to the regulatory mechanisms and control of glycogen metabolism. The concluding session covers the genetic analysis and biochemical characterization of the enzymes involved in the glycosidic linkage metabolism. Biochemists and carbohydrate researchers will find this text invaluable.

  • An Introduction to Numerical Classification

    • 1st Edition
    • Bozzano G Luisa
    • English
    An Introduction to Numerical Classification describes the rationale of numerical analyses by means of geometrical models or worked examples without possible extensive algebraic symbolism. Organized into 13 chapters, the book covers both the taxonomic and ecological aspects of numerical classification. After briefly presenting different terminologies used in this work, the book examines several types of biological classification, including classification by structure, proximity, similarity, and difference. It then describes various ecological and taxonomic data manipulations, such as data reduction, transformation, and standardization. Other chapters deal with the criteria for best computer classification and the complexities and difficulties in this classification. These difficulties are illustrated by reference to studies of the ""bottom communities"" of benthic marine invertebrates, ranging across the entire field from the sampling program and nature of the data to problems over the type of computer used. The concluding chapters consider some of the measures of diversity and the interpretations which have been made from them, as well as the relationship of diversity to classification. The concept and application in biological classification of various multivariate analyses are also discussed in these texts. Supplemental texts on the information measures, partitioning, and interdependence of data diversity are also provided. This book is of value to biologists and researchers who are interested in basic biological numerical classification.

  • Herbivorous Insects

    Host-seeking Behavior and mechanisms
    • 1st Edition
    • Sami Ahmad
    • English
    Herbivorous Insects: Host-Seeking Behavior and Mechanisms addresses mechanisms of searching behavior leading ultimately to host location of herbivorous insects. It is divided into four sections, wherein the first two sections deal with neurophysiology and the diversity of behavioral induction cues. The third section covers the searching mechanisms as affected by insects' breadth of diet. The last part examines the evolutionary analysis of the behavioral and physiological adaptations in insect/host plant relations. This book starts with an introduction to the chemical sensory system as it relates to host selection in general. This is followed by considerable discussions on host-seeking behavior and allied patterns in behavior. This text also includes the study of oviposition behavior in butterflies belonging to Papilionidae. The third section presents host selection and colonization by three insects within the saprophage-predator continuum, namely, Hylurgopinus rufipes, Scolytus multistriatus, and Pissodes strobi. The behaviors by which certain oligophagous insects locate and select food plants are also considered. The concluding part addresses the unifying theme and the diversity of responses of phytophagous insects to plants. The book provides direction toward developing a unifying theme and improving the ability to unravel the complexities of insect/plant interactions. Behaviorists, ecologists, entomologists, evolutionary biologists, and physiologists will find this book invaluable.
