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.

Book Synopsis Insects and Wildlife by : Dr John Capinera

Download or read book Insects and Wildlife written by Dr John Capinera. This book was released on 2011-09-13. Available in PDF, EPUB and Kindle. Book excerpt: Insects and Wildlife: Arthropods and their Relationships with Wild Vertebrate Animals provides a comprehensive overview of the interrelationships of insects and wildlife. It serves as an introduction to insects and other arthropods for wildlife management and other vertebrate biology students, and emphasizes the importance of insects to wild vertebrate animals. The book emphasizes how insects exert important influences on wildlife habitat suitability and wildlife population sustainability, including their direct and indirect effects on wildlife health. Among the important topics covered are: the importance of insects as food items for vertebrate animals; the role of arthropods as determinants of ecosystem health and productivity; the ability of arthropods to transmit disease-causing agents; an overview of representative disease-causing agents transmitted by arthropods; arthropods as pests and parasites of vertebrates; the hazards to wildlife associated with using using pesticides to protect against insect damage; insect management using techniques other than pesticides; the importance of insect conservation and how insects influence wildlife conservation.

Book Synopsis Insects and Other Arthropods of Tropical America by : Paul E. Hanson

Download or read book Insects and Other Arthropods of Tropical America written by Paul E. Hanson. This book was released on 2016-06-15. 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.

Book Synopsis Arthropod Brains by : Nicholas James Strausfeld

Download or read book Arthropod Brains written by Nicholas James Strausfeld. This book was released on 2012-01-02. 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.
