Download or read book Comparative Color Vision written by Gerald Jacobs and published by Elsevier. This book was released on 2013-06-11 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comparative Color Vision provides information about the means by which color vision has been studied in nonhuman animals and about the outcomes of these studies for a variety of representative species. Individuals who become interested in color vision in animals come from a variety of different educational backgrounds—from the traditional biological and behavioral sciences as well as from more applied fields. Accordingly, this book includes sufficient tutorial information about color vision so that a relative newcomer would be able to make sense out of this area without having to search out still more background material. To provide this, basic information about the psychophysics of color vision and about the methods used to study color vision in animals is presented; along with coverage of the broad range of biological mechanisms responsible for color vision. Subsequent chapters present systematic reviews of studies of color vision in a wide selection of vertebrate species. The final chapter is devoted to a discussion of two fascinating issues raised by studies of animal color vision: the evolutionary origins and the functional utility of color vision.
Download or read book Color Vision Sensitivity in Normally Dichromatic Species and Humans written by Richard E. Van Arsdel and published by . This book was released on 2002-09-01 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectral sensitivity functions for large, long-duration spectral stimuli presented on a photopic white background indicate that wavelength opponent mechanisms mediate detection of such stimuli in both normal and dichromatic humans. Normal humans detect the color of spectral flashes at detection threshold intensities, supporting the premise that wavelength opponent processes signal color. However, dichromatic humans do not see some colors at threshold; rather, they require stimuli up to about 0.4 log units above detection intensity. This suggests that dichiomatic humans may have a defect in postre- ceptoral color processing. To test this, we determined color discrimination thresholds in normally occurring dichromats, including the chipmunk, the 13-lined ground squirrel, and the tree shrew.

Download or read book Microbial Zoonoses and Sapronoses written by Zdenek Hubálek and published by Springer Science & Business Media. This book was released on 2010-11-25 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the state of art in the field of microbial zoonoses and sapronoses. It could be used as a textbook or manual in microbiology and medical zoology for students of human and veterinary medicine, including Ph.D. students, and for biomedicine scientists and medical practitioners and specialists as well. Surprisingly, severe zoonoses and sapronoses still appear that are either entirely new (e.g., SARS), newly recognized (Lyme borreliosis), resurging (West Nile fever in Europe), increasing in incidence (campylobacterosis), spatially expanding (West Nile fever in the Americas), with a changing range of hosts and/or vectors, with changing clinical manifestations or acquiring antibiotic resistance. The collective term for those diseases is (re)emerging infections, and most of them represent zoonoses and sapronoses (the rest are anthroponoses). The number of known zoonotic and sapronotic pathogens of humans is continually growing − over 800 today. In the introductory part, short characteristics are given of infectious and epidemic process, including the role of environmental factors, possibilities of their epidemiological surveillance, and control. Much emphasis is laid on ecological aspects of these diseases (haematophagous vectors and their life history; vertebrate hosts of zoonoses; habitats of the agents and their geographic distribution; natural focality of diseases). Particular zoonoses and sapronoses are then characterized in the following brief paragraphs: source of human infection; animal disease; transmission mode; human disease; epidemiology; diagnostics; therapy; geographic distribution.

Covers the technical aspects of thermal imaging allowing readers to design better experiments Provides a clear description of the properties of thermal imaging Includes approaches to consider before integrating thermal cameras into a field
Download or read book When Species Meet written by Donna J. Haraway and published by U of Minnesota Press. This book was released on 2013-11-30 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2006, about 69 million U.S. households had pets, giving homes to around 73.9 million dogs, 90.5 million cats, and 16.6 million birds, and spending more than 38 billion dollars on companion animals. As never before in history, our pets are truly members of the family. But the notion of “companion species”—knotted from human beings, animals and other organisms, landscapes, and technologies—includes much more than “companion animals.” In When Species Meet, Donna J. Haraway digs into this larger phenomenon to contemplate the interactions of humans with many kinds of critters, especially with those called domestic. At the heart of the book are her experiences in agility training with her dogs Cayenne and Roland, but Haraway’s vision here also encompasses wolves, chickens, cats, baboons, sheep, microorganisms, and whales wearing video cameras. From designer pets to lab animals to trained therapy dogs, she deftly explores philosophical, cultural, and biological aspects of animal–human encounters. In this deeply personal yet intellectually groundbreaking work, Haraway develops the idea of companion species, those who meet and break bread together but not without some indigestion. “A great deal is at stake in such meetings,” she writes, “and outcomes are not guaranteed. There is no assured happy or unhappy ending-socially, ecologically, or scientifically. There is only the chance for getting on together with some grace.” Ultimately, she finds that respect, curiosity, and knowledge spring from animal–human associations and work powerfully against ideas about human exceptionalism.
