Available in PDF, EPUB and Kindle. Book excerpt: Writers on arthropod water relationships range from bio physicists and biochemists to population ecologists-a fact that gives cause to wonder whether the field is already too heterogeneous to be written about in a single book by a single author. I have partly avoided the problem by concentrating largely on physiological mechanisms and by omitting most aspects of behavioural regulation and most aspects of heat balance and body temperature, except when these impinge directly on water balance. Even within this limited field there has been a lot of work during the past twenty years, as a result of which some problems have been solved (or at least more clearly defined), and many others have been opened up. On the whole there has been a welcome change to a more rigorous experimental approach and it is now possible for water balance people to state their problems in physiological terms. Good progress has been made towards understanding the mechanisms involved in nearly all avenues of water uptake and loss, although problems indeed remain. The cuticle has yielded part of its secrets to electron micrography, but ex ploration by means oflipid biochemistry among other techniques is necessary for a real understanding of cuticle permeability.

Download or read book Terrestrial Isopod Biology written by A.M. Alikhan and published by CRC Press. This book was released on 2018-04-20 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text contains the papers of a meeting on American isopods, the only crustacean group with representatives in all terrestrial ecosystems ranging from the sea shore to the desert. Due to such adaptibility, this group can be seen as a model for the successful transition on land. The text deals with two main subjects: the effects of stressful conditions on the individual animal as reflected by its survival or by the disruption of its normal reproductive pattern; and the distribution of the isopods and their selection of microhabitat.

Download or read book Regulation Digestion Nutrition Excretion written by G. A. Kerkut and published by Elsevier. This book was released on 2013-10-22 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume, seven of the chapters deal with feeding and diet, which is reasonable since insects consume an estimated l5-20% of all the world's planted crops. Many insects even have a specialized larval feeding stage that usually occupies a different ecological niche to the adult and so does not compete for the adult's food stock. Other chapters describe the means by which insects maintain their water balance, nitrogen balance and temperature balance under a range of conditions. These involve regulation by hormonal and behavioural systems that are also described here. The l4 chapters are all extensively illustrated and referenced and therefore provide excellent summaries of current knowledge. They will be of great value to entomologists, zoologists and biologists in general.

Download or read book The Colonisation of Land written by Colin Little and published by Cambridge University Press. This book was released on 1983-12-15 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book traces the ways in which terrestrial animals have evolved from aquatic ancestors and discusses the means by which they are adapted to life on land. The most important physiological adaptations are those involving salt and water balance, the excretion of nitrogen, reproductive mechanisms and the sense organ and these are given priority. Evidence from fossil history is combined with that from the ecology and physiology of present-day species to assess the probable routes along which various evolutionary lines had moved on to land. Individual chapters are concerned with specific animal groups and emphasis is placed on comparisons of physiological mechanisms between closely related animals before attempting wider generalisations. The book closes with a brief account of the recolonisation of the sea and fresh waters by terrestrial animals.

Download or read book The Insects written by R. F. Chapman and published by Cambridge University Press. This book was released on 2012-11-12 with total page 963 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Insects has been the standard textbook in the field since the first edition published over forty years ago. Building on the strengths of Chapman's original text, this long-awaited 5th edition has been revised and expanded by a team of eminent insect physiologists, bringing it fully up-to-date for the molecular era. The chapters retain the successful structure of the earlier editions, focusing on particular functional systems rather than taxonomic groups and making it easy for students to delve into topics without extensive knowledge of taxonomy. The focus is on form and function, bringing together basic anatomy and physiology and examining how these relate to behaviour. This, combined with nearly 600 clear illustrations, provides a comprehensive understanding of how insects work. Now also featuring a richly illustrated prologue by George McGavin, this is an essential text for students, researchers and applied entomologists alike.

Download or read book Nature at Work the Ongoing Saga of Evolution written by V. P. Sharma and published by Springer Science & Business Media. This book was released on 2011-12-27 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Charles Robert Darwin was born on 12th February, 1809 in Shrewsbury, England. Darwin shares his birthday with U. S. President Abraham Lincoln. Both were crusaders against slavery: Darwin disliked slavery and Lincoln abolished it. Darwin was a born naturalist and showed keen interest in nature from the very beginning. A breakthrough came when he was selected as a naturalist on the H. M. S. Beagle ship. His ?ve year voyage on the Beagle started in 1931 and was completed in 1936. This was followed by publication of his research ?ndings that challenged creationist views of the church. Darwin conducted a study of fossils and geological records and concluded rightly, that all life forms emerged over millions of years of evolution through the force of natural selection. In 1959 Darwin published his work on evolution in a book titled “On the Origin of Species by Means of Natural Selection or the Preservation of Favored Races”. The book was received as a scienti?c bomb shell and has since changed the human understanding of life forever. Today Darwin’s ideas on evolution provide foundation to modern biology. Darwin died of a heart attack on the 19th April 1882 and was buried in Westminster Abbey near the grave of Sir Isaac Newton. The scienti?c community is celebrating Darwin’s bicentenary worldwide in honor of his ingenuity, scienti?c thought, conviction and courage.

Download or read book Physiology of Ticks written by Frederick D. Obenchain and published by Elsevier. This book was released on 2013-10-22 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiology of Ticks focuses on the unique (and probably the most vulnerable) features of tick physiology and the physiological aspects of tick interactions with their hosts. The mechanisms used by non-feeding ticks to maintain their water balance are examined, along with the salivary mechanisms used by feeding ixodid ticks for excreting the enormous excess volumes of water and salts taken in during blood sucking. This book is comprised of 13 chapters and begins with a description of the morphology, deposition, and components of the tick cuticle. The discussion then turns to humidity relationships and water balance of ticks, as well as the sensory basis of tick feeding behavior and the immunological basis of host resistance to ticks. Subsequent chapters explore blood digestion in ticks; tick reproduction, with emphasis on sperm development, cytogenetics, oogenesis, and oviposition; effects of insect hormones and their mimics on tick development and reproduction; and the mechanisms of tick pheromones. The final chapter deals with diapause and biological rhythms in ticks. This monograph will be of value to entomologists, physiologists, biologists, and practitioners of tropical science.

Download or read book A Companion to Animal Physiology written by C. Richard Taylor and published by CUP Archive. This book was released on 1982-04-30 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1982, this book was designed to supplement Knut Schmidt-Nielsen's Animal Physiology. Using Schmidt-Nielsen's comparative approach to the study of animal form function, the text pursues in greater detail topics introduced in Animal Physiology. Like the textbook, the Companion is organised according to major environmental features: oxygen, food and energy, temperature, and water, concluding with a section on movement and structure. The papers brought together in this volume were presented in July 1980 to honour Smith-Nielsen's sixty-fifth birthday, at the Fifth International Conference on Comparative Physiology, held in Sandbjerg, Denmark.

Download or read book Insects at Low Temperature written by Richard Lee and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of insects at low temperature is a comparatively new field. Only recently has insect cryobiology begun to mature, as research moves from a descriptive approach to a search for underlying mechanisms at diverse levels of organization ranging from the gene and cell to ecological and evolutionary relationships. Knowledge of insect responses to low temperature is crucial for understanding the biology of insects living in seasonally varying habitats as well as in polar regions. It is not possible to precisely define low temperature. In the tropics exposure to 10-15°C may induce chill coma or death, whereas some insects in temperate and polar regions remain active and indeed even able to fly at O°C or below. In contrast, for persons interested in cryopreservation, low temperature may mean storage in liquid nitrogen at - 196°C. In the last decade, interest in adaptations of invertebrates to low temperature has risen steadily. In part, this book had its origins in a symposium on this subject that was held at the annual meeting of the Entomological Society of America in Louisville, Kentucky, USA in December, 1988. However, the emergence and growth of this area has also been strongly influenced by an informal group of investigators who met in a series of symposia held in Oslo, Norway in 1982, in Victoria, British Columbia, Canada in 1985 and in Cambridge, England in 1988. Another is scheduled for Binghamton, New York, USA (1990).
