Available in PDF, EPUB and Kindle. Book excerpt: Why do zebras have stripes? Popular explanations range from camouflage to confusion of predators, social facilitation, and even temperature regulation. It is a challenge to test these proposals on large animals living in the wild, but using a combination of careful observations, simple field experiments, comparative information, and logic, Caro concludes that black-and-white stripes are an adaptation to thwart biting fly attack.

Download or read book Biology of Blood Sucking Insects written by Mike Lehane and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blood-sucking insects are the vectors of many of the most debilitating parasites of man and his domesticated animals. In addition they are of considerable direct cost to the agricultural industry through losses in milk and meat yields, and through damage to hides and wool, etc. So, not surprisingly, many books of medical and veterinary entomology have been written. Most of these texts are organized taxonomically giving the details of the life-cycles, bionomics, relationship to disease and economic importance of each of the insect groups in turn. I have taken a different approach. This book is topic led and aims to discuss the biological themes which are common in the lives of blood-sucking insects. To do this I have concentrated on those aspects of the biology of these fascinating insects which have been clearly modified in some way to suit the blood-sucking habit. For example, I have discussed feeding and digestion in some detail because feeding on blood presents insects with special problems, but I have not discussed respiration because it is not affected in any particular way by haematophagy. Naturally there is a subjective element in the choice of topics for discussion and the weight given to each. I hope that I have not let my enthusiasm for particular subjects get the better of me on too many occasions and that the subject material achieves an overall balance.

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 The Geographical Distribution of Animal Viral Diseases written by Stewart Hal and published by Elsevier. This book was released on 2012-12-02 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Geographical Distribution of Animal Viral Diseases attempts to shed some light on the global distribution of 110 different viral diseases, mainly of livestock and companion animals. The world literature was screened for 110 different viruses, and maps were prepared. These maps delineate the global distribution of pathogenic viruses based on authenticated reports from a variety of reliable sources. Four viruses were categorized as affecting more than one species to a significant degree (astrovirus, rabies, rotaviruses, and Rift Valley fever). The largest number of maps involved viruses that affect humans. Of the 28 viruses a large number were from the California encephalitis group. Ten of the 28 viruses were reported only in the Eastern Hemisphere, 14 only in the Western Hemisphere, and four were worldwide. Birds were the next most frequently affected group with the 15 viruses, followed by pigs with 14 viruses. Overall the vector-borne viruses appear to have much sharper and clear-cut geographical boundaries than the others.

Download or read book What s Bugging You written by Arthur V. Evans and published by University of Virginia Press. This book was released on 2008 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are told from the time we are children that insects and spiders are pests, when the truth is that most have little or no effect on us--although the few that do are often essential to our existence. Arthur Evans suggests we take a closer look at our slapped-at, stepped-on, and otherwise ignored cohabitants, who vastly outnumber us and whose worlds often occupy spaces that we didn't even know existed. What's Bugging You? brings together fifty unforgettable stories from the celebrated nature writer and entomologist's popular Richmond Times-Dispatch column. Evans has scoured Virginia's wild places and returned with wondrous stories about the seventeen-year sleep of the periodical cicadas, moths that evade hungry bats by sensing echolocation signals, and the luminous language of light employed by fireflies. He also visits some not-so-wild places: the little mounds of upturned soil scattered along the margins of soccer fields are the dung beetle's calling card. What does the world look like to a bug? Evans explores insect vision, which is both better, and worse, than that of humans (they are capable of detecting ultraviolet light, but many cannot see the color red), pausing to observe that it is its wide-set forward-looking eyes that imbue the praying mantis with "personality." He is willing to defend such oft-maligned creatures as the earwig, the tent caterpillar, and the cockroach--revealed here as a valuable scavenger, food source for other animals, and even a pollinator, that spends more time grooming itself than it does invading human space. Evans's search for multilegged life takes him to an enchanting assortment of locations, ranging from gleaming sandy beaches preferred by a threatened tiger beetle to the shady, leaf-strewn forest floors where a centipede digs its brood chamber--to a busy country road where Evans must dodge constant foot and vehicular traffic to photograph a spider wasp as its claims its paralyzed prey. His forays also provide the reader with a unique window on the cycles of nature. What Evans refers to as the FBI--fungus, bacteria, insects--are the chief agents in decomposition and a vital part of regeneration. Evans also takes on many issues concerning humans' almost always destructive interaction with insect life, such as excessive mowing and clearing of wood that robs wildlife of its food and habitat, as well as harmful bug zappers that kill everything but mosquitoes. The reader emerges from this book realizing that even seemingly mundane forms of insect and spider life present us with unexpected beauty and fascinating lifestyles.

Download or read book Biology of Snail Killing Sciomyzidae Flies written by Lloyd Knutson and published by Cambridge University Press. This book was released on 2011-09-29 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written for academic researchers and graduate students in entomology, this is the first comprehensive analysis of Sciomyzid flies. Sciomyzid flies are important as prime candidates for the biological control of snails and slugs that help transmit diseases such as schistosomiasis or are important agricultural pests. They also serve as a paradigm for the study of the evolution of feeding behavior in predatory insects. Starting with analyses of malacophagy in general and then in Diptera specifically, all important aspects of the Sciomyzidae are discussed, including behavior, ecology, life cycles, morphology, and identification. New behavioral and morphological classifications and hypotheses are proposed on the basis of unpublished information and a complete analysis of the extensive literature. Also included are keys to adults, larvae and puparia and a checklist of world species, with information on geographical range and the location of type specimens. The accompanying DVD includes Clifford O. Berg's classic film on the biology of Sciomyzidae and biological control of snails.

Download or read book Polarized Light in Animal Vision written by Gábor Horváth and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of this volume is two-fold. First, it gathers typical polarization patterns occurring in nature. Second, it surveys the polarization-sensitive ani mals, the physiological mechanisms and biological functions of polarization sensitivity as weIl as the polarization-guided behaviour in animals. The monograph is prepared for biologists, physicists and meteorologists, espe cially for experts of atmospheric optics and animal vision, who wish to under stand and reveal the message hidden in polarization patterns of the optical environment not directly accessible to the human visual system, but measur able by polarimetry and perceived by many animals. Our volume is an attempt to build a bridge between these two physical and biological flelds. In Part I we introduce the reader to the elements of imaging polarimetry. This technique can be efflciently used, e. g. in atmospheric optics, remote sens ing and biology. In Part 11 we deal with typical polarization patterns of the natural optical environment. Sunrise/sunset, clear skies, cloudy skies, moonshine and total solar eclipses all mean quite different illumination conditions, wh ich also affect the spatial distribution and strength of celestial polarization. We pre sent the polarization patterns of the sky and its unpolarized (neutral) points under sunlit, moonlit, clear, cloudy and eclipsed conditions as a function of solar elevation. The polarization pattern of a rainbow is also shown. That part of the spectrum is derived in which perception of skylight polarization is optimal under partly cloudy skies.
