Download or read book Arthropod Brains written by Nicholas James Strausfeld and published by Harvard University Press. This book was released on 2012-01-02 with total page 849 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Descent of Man, Charles Darwin proposed that an ant’s brain, no larger than a pin’s head, must be sophisticated to accomplish all that it does. Yet today many people still find it surprising that insects and other arthropods show behaviors that are much more complex than innate reflexes. They are products of versatile brains which, in a sense, think. Fascinating in their own right, arthropods provide fundamental insights into how brains process and organize sensory information to produce learning, strategizing, cooperation, and sociality. Nicholas Strausfeld elucidates the evolution of this knowledge, beginning with nineteenth-century debates about how similar arthropod brains were to vertebrate brains. This exchange, he shows, had a profound and far-reaching impact on attitudes toward evolution and animal origins. Many renowned scientists, including Sigmund Freud, cut their professional teeth studying arthropod nervous systems. The greatest neuroanatomist of them all, Santiago Ramón y Cajal—founder of the neuron doctrine—was awed by similarities between insect and mammalian brains. Writing in a style that will appeal to a broad readership, Strausfeld weaves anatomical observations with evidence from molecular biology, neuroethology, cladistics, and the fossil record to explore the neurobiology of the largest phylum on earth—and one that is crucial to the well-being of our planet. Highly informative and richly illustrated, Arthropod Brains offers an original synthesis drawing on many fields, and a comprehensive reference that will serve biologists for years to come.
Download or read book Arthropods and Human Skin written by John O'Donel Alexander and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: To the entomologist all insects have six legs; the layman tends to use the term "insect" to include the eight-legged spiders and mites. All these creatures are correctly classified as arthropods. Many thousands of the hundreds of thousands of recognised species of arthropods are found in the human environment-domestic, occupational and rec reational. Those species which are obligate parasites of man, the human scabies mite and the head and body lice, produce familiar clinical syndromes. They remain important in medical practice and have been the subject of a great deal of recent research. This is beginning to throw much light on the immunological mechanisms which largely determine the reactions of the host. Dr. Alexander has provided a detailed survey of this work. The wasps, bees, ants and other Hymenoptera which may sting man in self-defence can cause painful, even fatal reactions. The recent work on this important subject has also been thoroughly reviewed. Every dermatologist of experience will admit that he sees many patients in whom he makes a diagnosis of "insect bites", if he has the confidence to do so, or of "papular urticaria" or "prurigo" when he lacks such confidence, mainly because he is at a loss to know which arthropod is likely to be implicated. In his survey of the enormous literature in the entomological, public health and dermatology journals Dr. Alexander has provided an invaluable guide in which the solutions to these clinical mysteries can be sought.
Download or read book Crustacea and Arthropod Relationships written by Stefan Koenemann and published by CRC Press. This book was released on 2005-04-27 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compared to other arthropods, crustaceans are characterized by an unparalleled disparity of body plans. Traditionally, the specialization of arthropod segments and appendages into distinct body regions has served as a convenient basis for higher classification; however, many relationships within the phylum Arthropoda still remain controversial.
Download or read book Principles of Insect Morphology written by R. E. Snodgrass and published by Cornell University Press. This book was released on 2018-05-31 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: This classic text, first published in 1935, is once again available. Still the standard reference in the English language, Principles of Insect Morphology is considered the author's masterpiece. A talented artist as well as one of the leading entomologists of his day, Robert E. Snodgrass produced a wealth of publications that display an accuracy and precision still unsurpassed. The 19 chapters in this volume cover each group of insect organs and their associated structures, at the same time providing a coherent morphological view of their fundamental nature and apparent evolution. To accomplish this aim, Snodgrass compares insect organs with those of other arthropods. Each chapter concludes with a glossary of terms. The 319 multipart illustrations are an invaluable source of information and have never been duplicated. This edition includes a new foreword by George Eickwort, Professor of Entomology at Cornell University, which relates the book to today's courses in insect morphology. Republication of this textbook will provide another generation of students with an essential foundation for their studies in entomology.
Download or read book Arthropod Biology and Evolution written by Alessandro Minelli and published by Springer Science & Business Media. This book was released on 2013-04-11 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than two thirds of all living organisms described to date belong to the phylum Arthropoda. But their diversity, as measured in terms of species number, is also accompanied by an amazing disparity in terms of body form, developmental processes, and adaptations to every inhabitable place on Earth, from the deepest marine abysses to the earth surface and the air. The Arthropoda also include one of the most fashionable and extensively studied of all model organisms, the fruit-fly, whose name is not only linked forever to Mendelian and population genetics, but has more recently come back to centre stage as one of the most important and more extensively investigated models in developmental genetics. This approach has completely changed our appreciation of some of the most characteristic traits of arthropods as are the origin and evolution of segments, their regional and individual specialization, and the origin and evolution of the appendages. At approximately the same time as developmental genetics was eventually turning into the major agent in the birth of evolutionary developmental biology (evo-devo), molecular phylogenetics was challenging the traditional views on arthropod phylogeny, including the relationships among the four major groups: insects, crustaceans, myriapods, and chelicerates. In the meantime, palaeontology was revealing an amazing number of extinct forms that on the one side have contributed to a radical revisitation of arthropod phylogeny, but on the other have provided evidence of a previously unexpected disparity of arthropod and arthropod-like forms that often challenge a clear-cut delimitation of the phylum.
Download or read book Economic and Ecological Significance of Arthropods in Diversified Ecosystems written by Akshay Kumar Chakravarthy and published by Springer. This book was released on 2016-10-20 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arthropods are invertebrates that constitute over 90% of the animal kingdom, and their bio-ecology is closely linked with global functioning and survival. Arthropods play an important role in maintaining the health of ecosystems, provide livelihoods and nutrition to human communities, and are important indicators of environmental change. Yet the population trends of several arthropods species show them to be in decline. Arthropods constitute a dominant group with 1.2 million species influencing earth’s biodiversity. Among arthropods, insects are predominant, with ca. 1 million species and having evolved some 350 million years ago. Arthropods are closely associated with living and non-living entities alike, making the ecosystem services they provide crucially important. In order to be effective, plans for the conservation of arthropods and ecosystems should include a mixture of strategies like protecting key habitats and genomic studies to formulate relevant policies for in situ and ex situ conservation. This two-volume book focuses on capturing the essentials of arthropod inventories, biology, and conservation. Further, it seeks to identify the mechanisms by which arthropod populations can be sustained in terrestrial and aquatic ecosystems, and by means of which certain problematic species be managed without producing harmful environmental side-effects. This edited compilation includes chapters contributed by over 80 biologists on a wide range of topics embracing the diversity, distribution, utility and conservation of arthropods and select groups of insect taxa. More importantly, it describes in detail the mechanisms of sustaining arthropod ecosystems, services and populations. It addresses the contribution of modern biological tools such as molecular and genetic techniques regulating gene expression, as well as conventional, indigenous practices in arthropod conservation. The contributors reiterate the importance of documenting and understanding the biology of arthropods from a holistic perspective before addressing conservation issues at large. This book offers a valuable resource for all zoologists, entomologists, ecologists, conservation biologists, policy makers, teachers and students interested in the conservation of biological resources.
Download or read book Optical Manipulation of Arthropod Pests and Beneficials written by David Ben-Yakir and published by CABI. This book was released on 2020-06-05 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arthropods as pests in crops, vectors of diseases, pollinators, and natural enemies of pests are of huge economic importance. They affect livestock, human health and food supplies around the world. This unique book examines and reviews how light and colour can be used to enhance pest management in agricultural and medical applications by manipulating the optical responses of arthropods. Arthropods use optical cues to find food, oviposition sites and to navigate. Light also regulates their diurnal and seasonal activities. Plants use optical cues to attract or deter various species of arthropod. In this book, an international team of experts show how light can be used successfully to attract, arrest, confuse and deter arthropods as well as to disrupt their biological clocks.

Download or read book Arthropod Venom Components and Their Potential Usage written by Katsuhiro Konno and published by MDPI. This book was released on 2020-03-25 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thousands of arthropod species, ranging from arachnids (spiders and scorpions) to hymenopterans (ants, bees, and wasps) and myriapods (centipedes), are venomous and use their venoms for both defense and predation. These venoms are invariably harmful to humans, and some may cause serious injuries, e.g., those from scorpions, spiders, and wasps. Arthropods’ venoms are also known as rich sources of biologically active compounds and have attracted the attention of toxin researchers for years. In this century, venom component analysis has progressed considerable due to the advances in analytical techniques, in particular, mass spectrometry and next-generation deep (DNA and RNA) sequencing. As such, proteomic and peptidomic analyses using LC–MS have enabled the full analysis of venom components, revealing a variety of novel peptide and protein toxins sequences and scaffolds, potentially useful as pharmacological research tools and for the development of highly selective peptide ligands and therapeutic leads, like chlorotoxin. Due to their specificity for numerous ion-channel subtypes, including voltage- and ligand-gated ion channels, arthropod neurotoxins have been investigated to dissect and treat neurodegenerative diseases and control epileptic syndromes. This Special Issue collects information on such progress, encouraging contributions on the chemical and biological characterization of venom components, not only peptides and proteins, but also small molecules, their mechanisms of action, and the development of venom-derived peptide leads.
Download or read book Medical Insects and Arachnids written by R.P. Lane and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 733 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surprising though it seems, the world faces almost as great a threat today from arthropod-borne diseases as it did in the heady days of the 1950s when global eradication of such diseases by eliminating their vectors with synthetic insecticides, particularly DDT, seemed a real possibility. Malaria, for example, still causes tremendous morbidity and mortality throughout the world, especially in Africa. Knowledge of the biology of insect and arachnid disease vectors is arguably more important now than it has ever been. Biological research directed at the development of better methods of control becomes even more important in the light of the partial failure of many control schemes that are based on insecticide- although not all is gloom, since basic biological studies have contributed enormously to the outstanding success of international control programmes such as the vast Onchocerciasis Control Programme in West Africa. It is a sine qua non for proper understanding of the epidemiology and successful vector control of any human disease transmitted by an arthropod that all concerned with the problem - medical entomologist, parasitologist, field technician - have a good basic understanding of the arthropod's biology. Knowledge will be needed not only of its direct relationship to any parasite or pathogen that it transmits but also of its structure, its life history and its behaviour - in short, its natural history. Above all, it will be necessary to be sure that it is correctly identified.
Download or read book Measuring Arthropod Biodiversity written by Jean Carlos Santos and published by Springer Nature. This book was released on 2020-11-11 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together a wide range of sampling methods for investigating different arthropod groups. Each chapter is organized to describe and evaluate the main sampling methods (field methods, materials and supplies, sampling protocols, effort needed, and limitations); in addition, some chapters describe the specimen preparation and conservation, species identification, data collection and management (treatment, statistical analysis, interpretation), and ecological/conservation implications of arthropod communities. The book aims to be a reference for zoologists, entomologists, arachnologists, ecologists, students, researchers, and for those interested in arthropod science and biodiversity. We hope the book will contribute to advance knowledge on field assessments and conservation strategies. Arthropods represent the most speciose group of organisms on Earth, with a remarkable number of species and interactions still to be described. These invertebrates are recognized for playing key ecological roles in terrestrial, freshwater and marine ecosystems. Because of the increasing and relentless threats arthropods are facing lately due to a multitude of human induced drivers, this book represents an important contribution to assess their biodiversity and role in ecosystem functioning and generation of ecosystem services worldwide.

Download or read book Insects and Other Arthropods of Tropical America written by Paul E. Hanson and published by Cornell University Press. This book was released on 2016-06-15 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visitors to tropical forests generally come to see the birds, mammals, and plants. Aside from butterflies, however, insects usually do not make it on the list of things to see. This is a shame. Insects are everywhere, they are often as beautiful as the showiest of birds, and they have a fascinating natural history. With their beautifully illustrated guide to insects and other arthropods, Paul E. Hanson and Kenji Nishida put the focus on readily observable insects that one encounters while strolling through a tropical forest in the Americas. It is a general belief that insects in the tropics are larger and more colorful than insects in temperate regions, but this simply reflects a greater diversity of nearly all types of insects in the tropics. On a single rainforest tree, for example, you will find more species of ant than in all of England. Though written for those who have no prior knowledge of insects, this book should also prove useful to those who study them. In addition to descriptions of the principal insect families, the reader will find a wealth of biological information that serves as an introduction to the natural history of insects and related classes. Sidebars on insect behavior and ecological factors enhance the descriptive accounts. Kenji Nishida’s stunning photographs—many of which show insects in action in their natural settings—add appeal to every page. A final chapter provides a glimpse into the intriguing world of spiders, scorpions, crabs, and other arthropods.

Download or read book Glycoscience Biology and Medicine written by Tamao Endo and published by Springer. This book was released on 2021-01-14 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of the book is to provide a succinct overview of the current status of glycoscience from both basic biological and medical points of view and to propose future directions, in order to facilitate further integrations of glycoscience with other fields in biological and medical studies. Glycans (carbohydrate oligomers) are the so-called “building blocks” of carbohydrates, nucleic acids, proteins and lipids and play major roles in many biological phenomena as well as in various pathophysiological processes. However, this area of glycoscience has been neglected from the research community because glycan structures are very complex and functionally diverse and as compared to proteins and nucleic acids simple tools for the amplification, sequencing and auto-synthesis of glycans are not available. Many scientists in other fields of research have now realized that glycosylation, i.e. the addition of glycans to a protein backbone, is the most abundant post translational modification reactions and is an important field of research and sometimes they require a glycobiology and/or glycochemistry approach to be used. It is still difficult, however, for non-expert researchers to use these techniques. This book will provide numerous but simple overviews of current topics and protocols for the experiments. The book is aimed at university students and above, including non-experts in the field of glycoscience.
