Book Description
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.

Book Description
This book was written to show that light is a primal element of life. All life originates and develops under the influence of the light of the sun, that "super terrestrial natural force" (Goethe). Sunlight influences the vital processes not onlyofthe plant (e. g. , heliotropism, photosynthesis) and the animal (e. g. , color change, maturation of the gonads) but of man as well. The human organism too reacts "heliotropically," as the 24 hour rhythm of the sleep-waking cycle demonstrates. of Artists have always perceived clearly the intensive stimulatory effect sunlight on their activity. One is reminded here ofCesare Lombroso, who wrote to his daughter "that thoughts come in the greatest profusion when (my) room is flooded with the sun's rays. " Richard Wagner exclaimed: "Ifonly the sun would come out, I would have the score finished in no time. " Bernard Shaw had a little cottage where he worked that could be turned according to the position of the sun. The composer Humperdinck wrote: "The sun is indispensable for my work; that is why it is important for me to have my study face east or south. " As these few examples indicate, it is above all those active in the arts who intuitively grasp the positive influence of sunlight on the psycho-physical effi ciency of their organism. In an age, however, when fluorescent lighting turns night into day, we are in danger of forgetting that man is a creature of nature as well as of culture.

Book Description
"This book is intended for anyone interested in the actual behavior and nature of animals and the world we live in, and presents a good deal of ethological and mythological material. It is meant to be more than a mere compilation of facts. Caspari's is a holistic approach to the world. By contemplating the significance of our fellow creatures, and how everything in our universe is linked, it is the author's hope that we can have a more whole, and more healing view of the world."--Jacket.

Book Description
While certain ecological problems associated with artificial night lighting are widely known-for instance, the disorientation of sea turtle hatchlings by beachfront lighting-the vast range of influences on all types of animals and plants is only beginning to be recognized. From nest choice and breeding success of birds to behavioral and physiological changes in salamanders, many organisms are seriously affected by human alterations in natural patterns of light and dark. Ecological Consequences of Artificial Night Lighting is the first book to consider the environmental effects of the intentional illumination of the night. It brings together leading scientists from around the world to review the state of knowledge on the subject and to describe specific effects that have been observed across a full range of taxonomic groups, including mammals, birds, reptiles and amphibians, fishes, invertebrates, and plants. Ecological Consequences of Artificial Night Lighting provides a scientific basis to begin addressing the challenge of conserving the nighttime environment. It cogently demonstrates the vital importance of this until-now neglected topic and is an essential new work for conservation planners, researchers, and anyone concerned with human impacts on the natural world.

Book Description
"Animal Internet is a most important book. This excellent work could be a strong catalyst for people to rewild, to reconnect and become re-enchanted with all sorts of mysterious and fascinating animals, both local and distant. By shrinking the world it will bring humans and other animals together in a multitude of ways that only a few years ago were unimaginable." —Marc Bekoff, University of Colorado, author of Rewilding Our Hearts: Building Pathways of Compassion and Coexistence "An original book that goes against the trend to stubbornly keep nature and technology divided from one another."—Der Spiegel "Animal Internet is one of the most interesting books that I've read in recent years."—Bavarian Radio "What Pschera describes sounds futuristic but it's already widespread reality . . . Pschera's book is not just popular science: he describes not only the status quo, but also thinks about an ongoing transformation."—Wired.de Some fifty thousand creatures around the globe—including whales, leopards, flamingoes, bats, and snails—are being equipped with digital tracking devices. The data gathered and studied by major scientific institutes about their behavior will warn us about tsunamis, earthquakes and volcanic eruptions, but also radically transform our relationship to the natural world. With a broad cultural and historical perspective, this book examines human ties with animals, from domestic pets to the soaring popularity of bird watching and kitten images on the web. Will millennia of exploration soon be reduced to experiencing wilderness via smartphone? Contrary to pessimistic fears, author Alexander Pschera sees the Internet as creating a historic opportunity for a new dialogue between man and nature. Foreword by Martin Wikelski, Director, Max Planck Institute for Ornithology Alexander Pschera, born in 1964, has published several books on the internet and media. He studied German, music, and philosophy at Heidelberg University. He lives near Munich where he writes for the German magazine Cicero as well as for German radio.

Book Description
This book covers advances made since the 2004 Springer volume “Polarized Light in Animal Vision” edited by Horvath and Varju, but also provides reviews and synopses of some areas. Part I examines polarization sensitivity across many animal taxa including vertebrates and invertebrates and details both terrestrial and aquatic life. Part II is devoted to the description of polarized light in nature and explores how the physics of light must be taken into account when understanding how polarized light is detected by the visual system. This includes underwater polarization due to scattering; polarization patterns reflected from freshwater bodies; polarization characteristics of forest canopies; normal and anomalous polarization patterns of the skies; skylight polarization transmitted through Snell’s window and both linearly and circularly polarized signals produced by terrestrial and aquatic animals. This Part also examines polarized “light pollution” induced by anthropogenic factors such as reflection off asphalt surfaces, glass panes, car bodies, and other man-made structures that are now known to form ecological traps for polarotactic insects. Part III surveys some of the practical applications of polarization vision including polarization-based traps for biting insects, ground-based polarimetric cloud detectors and an historical examination of the navigational abilities of Viking seafarers using the sky polarization compass. The deterrent qualities of ungulate pelage to polarization-sensitive biting insects is also examined in this section.
