Scorpion PDF Author: Louise M. Pryke

ISBN: 1780236255

Languages : en
Pages : 223

Book Description
No creature has quite the sting in our mythology and folklore as the scorpion. From the dawn of human civilization they have been a dangerous figure in our imaginations—poisonous, precise, and deadly quiet—but as Louise M. Pryke shows in this book, their bad reputation has overshadowed many exceptional qualities. Scurrying across hundreds of millions of years and across every continent except Antarctica, this book gives the scorpion its due as one of nature’s longest lasting survivors. Indeed scorpions are older than dinosaurs. An ancient arthropod, their form—notable for its pair of pincers and an elegant tail that holds a menacing stinger high in the air in a permanent striking position—hasn’t changed since prehistoric times, though today there are some 1700 different species. Throughout our existence scorpions have served as a powerful cultural and religious symbol—sometimes dangerous, sometimes protecting—from the Egyptian goddess Serket to Zodiac astrology to folk medicine. A fascinating tour that takes us from the art of North Africa to the American Civil War to the markets of Beijing, Scorpion is an homage to one of earth’s oldest residents.

Topographic Organization of the Pectine Neuropils in Scorpions

Topographic Organization of the Pectine Neuropils in Scorpions PDF Author: Denise Drozd
Publisher: Springer
ISBN: 3658251557
Category : Science
Languages : en
Pages : 57

Book Description
Chelicerates do not possess dedicated antennae like the Mandibulata but have evolved their second sets of appendages into the eponymous chelicerae. In scorpions, pectines are specialized comb-like structures, located on the ninth body segment, used for examining the substrate for chemo- and mechanosensory signals. The comb teeth, or pegs, are truncated beveled structures facing the substrate for probing, and are studded with numerous sensory receptors. Afferents from the pectines project into a distinct neuropil of the central nervous system, located behind the fourth walking leg neuropils. Denise Drozd analyzes afferents of single pegs in Mesobuthus eupeus by backfilling, combined with immunohistological labeling of neuropil regions. Her results suggest a topographic representation of the chemosensory fibers within the pectine neuropil instead of the typical chemotopic representation.

The Tree with Many Branches

The Tree with Many Branches PDF Author: Tommy Rodriguez
Publisher: iUniverse
ISBN: 1663206481
Category : Science
Languages : en
Pages : 75

Book Description
Want to build an evolutionary tree? Here’s your chance to learn how. The field of bioinformatics was born out of the need to manage, analyze, and examine raw genomic data in meaningful and exciting ways, such as the discipline of computational phylogenetics would provide. The evolutionary inferences reached among the several peer-reviewed articles contained in this book are neither novel nor breakthrough. However, it is in the application of computational techniques, experiment design, and probabilistic models where this research finds a stronghold. As a matter of practicality, the original manuscripts have been edited for a broader audience due to its highly technical language. The essays compiled in these pages have undergone a facelift, from their original scientific format into a more reader-friendly layout, as to better accommodate two different perspectives – both experts and non-experts alike.

Medical and Veterinary Entomology

Medical and Veterinary Entomology PDF Author: Gary R. Mullen
Publisher: Academic Press
ISBN: 0128140445
Category : Science
Languages : en
Pages : 794

Book Description
The first and second editions of Medical and Veterinary Entomology, edited by Gary R. Mullen and Lance A. Durden, published in 2002 and 2009, respectively, have been highly praised and become widely used as a textbook for classroom instruction. This fully revised third edition continues the focus on the diversity of arthropods affecting human and animal health, with separate chapters devoted to each of the taxonomic groups of insects and arachnids of medical or veterinary concern, including spiders, scorpions, mites, and ticks. Each chapter includes sections on taxonomy, morphology, life history, and behavior and ecology, with separate sections on those species of public-health and veterinary importance. Each concludes with approaches to management of pest species and prevention of arthropod-borne diseases. The third edition provides a comprehensive source for teaching medical and/or veterinary entomology at the college and university level, targeted particularly at upper-level undergraduate and graduate/postgraduate programs. In addition to its value as a student textbook, the volume has appeal to a much broader audience, specialists and non-specialists alike. It provides a key reference for biologists in general, entomologists, zoologists, parasitologists, physicians, public-health personnel, veterinarians, wildlife biologists, vector biologists, military entomologists, the general public and others seeking a readable, authoritative account on this important topic. - Completely revised and updated edition - Includes a distinguished group of 40 nationally and internationally recognized contributors - Sixteen new authors, in addition to 25 continuing contributors from the first and second editions - A new chapter on Arthropod Toxins and Venoms - Illustrated with 560, mostly color, figures and updated maps depicting the distribution of important arthropod taxa and arthropod-borne diseases - A significantly expanded and well-illustrated chapter on Molecular Tools Used in Medical and Veterinary Entomology - Coverage of emerging and newly recognized arthropod concerns, including mosquito-borne Zika and - Chikungunya viruses; tick-borne Bourbon and Heartland viruses; tick-borne rickettsioses and anaplasmosis; and red meat allergy associated with tick bites - A 1700-word Glossary - An Appendix of Arthropod-Related Viruses of Medical and Veterinary Importance

Experimental Approaches to Understanding Fossil Organisms

Experimental Approaches to Understanding Fossil Organisms PDF Author: Daniel I. Hembree
Publisher: Springer Science & Business
ISBN: 9401787212
Category : Science
Languages : en
Pages : 425

Book Description
Paleontologists and geologists struggle with research questions often complicated by the loss or even absence of key paleobiological and paleoenvironmental information. Insight into this missing data can be gained through direct exploration of analogous living organisms and modern environments. Creative, experimental and interdisciplinary treatments of such ancient-Earth analogs form the basis of Lessons from the Living. This volume unites a diverse range of expert paleontologists, neontologists and geologists presenting case studies that cover a spectrum of topics, including functional morphology, taphonomy, environments and organism-substrate interactions.
