Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive treatment of visual ecology Visual ecology is the study of how animals use visual systems to meet their ecological needs, how these systems have evolved, and how they are specialized for particular visual tasks. Visual Ecology provides the first up-to-date synthesis of the field to appear in more than three decades. Featuring some 225 illustrations, including more than 140 in color, spread throughout the text, this comprehensive and accessible book begins by discussing the basic properties of light and the optical environment. It then looks at how photoreceptors intercept light and convert it to usable biological signals, how the pigments and cells of vision vary among animals, and how the properties of these components affect a given receptor's sensitivity to light. The book goes on to examine how eyes and photoreceptors become specialized for an array of visual tasks, such as navigation, evading prey, mate choice, and communication. A timely and much-needed resource for students and researchers alike, Visual Ecology also includes a glossary and a wealth of examples drawn from the full diversity of visual systems. The most up-to-date overview of visual ecology available Features some 225 illustrations, including more than 140 in color, spread throughout the text Guides readers from the basic physics of light to the role of visual systems in animal behavior Includes a glossary and a wealth of real-world examples

This book was released on 2013-04-17 with total page 674 pages. Available in PDF, EPUB and Kindle. Book excerpt: John Lythgoe was one of the pioneers of the 'Ecology of Vision', a subject that he ably delineated in his classic and inspirational book published some 20 years ago [1]. At heart, the original book aimed generally to identify inter-relationships between vision, animal behaviour and the environment. John Lythgoe excelled at identifying the interesting 'questions' in the ecology of an animal that fitted the 'answers' presented by an analysis of the visual system. Over the last twenty years, however, since Lythgoe's landmark publication, much progress has been made and the field has broadened considerably. In particular, our understanding of the 'adaptive mechanisms' underlying the ecology of vision has reached considerable depths, extending to the molecular dimension, partly as a result of development and application of new techniques. This complements the advances made in parallel in clinically oriented vision research [2]. The current book endeavours to review the progress made in the ecology of vision field by bringing together many of the major researchers presently active in the expanded subject area. The contents deal with theoretical and physical considerations of light and photoreception, present examples of visual system structure and function, and delve into aspects of visual behaviour and communi cation. Throughout the book, we have tried to emphasise one of the major themes to emerge within the ecology of vision: the high degree of adaptability that visual mechanisms are capable of undergoing in response to diverse, and dynamic, environments and behaviours.

Available in PDF, EPUB and Kindle. Book excerpt: This is a book about how we see: the environment around us (its surfaces, their layout, and their colors and textures); where we are in the environment; whether or not we are moving and, if we are, where we are going; what things are good for; how to do things (to thread a needle or drive an automobile); or why things look as they do. The basic assumption is that vision depends on the eye which is connected to the brain. The author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another. That is natural vision -- and what this book is about.

Book excerpt: Current patterns of land use and development are at once socially, economically, and environmentally destructive. Sprawling low-density development literally devours natural landscapes while breeding a pervasive sense of social isolation and exacerbating a vast array of economic problems. As more and more counties begin to look more and more the same, hope for a different future may seem to be fading. But alternatives do exist. The Ecology of Place, Timothy Beatley and Kristy Manning describe a world in which land is consumed sparingly, cities and towns are vibrant and green, local economies thrive, and citizens work together to create places of eduring value. They present a holistic and compelling approach to repairing and enhancing communities, introducing a vision of "sustainable places" that extends beyond traditional architecture and urban design to consider not just the physical layout of a development but the broad set of ways in which communities are organized and operate. Chapters examine: the history and context of current land use problems, along with the concept of "sustainable places" the ecology of place and ecological policies and actions local and regional economic development links between land-use and community planning and civic involvement specific recommendations to help move toward sustainability The authors address a variety of policy and development issues that affect a community -- from its economic base to its transit options to the ways in which its streets and public spaces are managed -- and examine the wide range of programs, policies, and creative ideas that can be used to turn the vision of sustainable places into reality. The Ecology of Place is a timely resource for planners, economic development specialists, students, and citizen activists working toward establishing healthier and more sustainable patterns of growth and development.

Available in PDF, EPUB and Kindle. Book excerpt: Seeing Whole: Toward an Ethics and Ecology of Sight explores the ways in which seeing as an embodied process is always a multivalent, ambiguous, and holistic undertaking. Looking at an image entails the mobilization of a range of affordances that together produce sight and insight as a phenomenological experience, namely cultural predispositions, geographical situatedness, medium specificity, personal biography, socio-political relationality, and corporeal affectibility. In their own diverse ways, the essays in this book suggest that acts of seeing make up a visual ecology that, in turn, introduces a new ethical horizon distinct from, but in continuous interaction with ,conventional ethics. Spanning a great variety of media forms – from painting and photography to film, video, literature, fashion, graffiti, and installation art – this interdisciplinary collection offers a thorough reconceptualization of the relation between the aesthetics and the ethics of images and represents an innovative addition to the field of visual culture studies.

Available in PDF, EPUB and Kindle. Book excerpt: Many readers drawn into the heroic tales of J. R. R. Tolkien's imaginary world of Middle-earth have given little conscious thought to the importance of the land itself in his stories or to the vital roles played by the flora and fauna of that land. As a result, The Hobbit, The Lord of the Rings, and The Silmarillion are rarely considered to be works of environmental literature or mentioned together with such authors as John Muir, Rachel Carson, or Aldo Leopold. Tolkien's works do not express an activist agenda; instead, his environmentalism is expressed in the form of literary fiction. Nonetheless, Tolkien's vision of nature is as passionate and has had as profound an influence on his readers as that of many contemporary environmental writers. The burgeoning field of agrarianism provides new insights into Tolkien's view of the natural world and environmental responsibility. In Ents, Elves, and Eriador, Matthew Dickerson and Jonathan Evans show how Tolkien anticipated some of the tenets of modern environmentalism in the imagined world of Middle-earth and the races with which it is peopled. The philosophical foundations that define Tolkien's environmentalism, as well as the practical outworking of these philosophies, are found throughout his work. Agrarianism is evident in the pastoral lifestyle and sustainable agriculture of the Hobbits, as they harmoniously cultivate the land for food and goods. The Elves practice aesthetic, sustainable horticulture as they shape their forest environs into an elaborate garden. To complete Tolkien's vision, the Ents of Fangorn Forest represent what Dickerson and Evans label feraculture, which seeks to preserve wilderness in its natural form. Unlike the Entwives, who are described as cultivating food in tame gardens, the Ents risk eventual extinction for their beliefs. These ecological philosophies reflect an aspect of Christian stewardship rooted in Tolkien's Catholic faith. Dickerson and Evans define it as "stewardship of the kind modeled by Gandalf," a stewardship that nurtures the land rather than exploiting its life-sustaining capacities to the point of exhaustion. Gandalfian stewardship is at odds with the forces of greed exemplified by Sauron and Saruman, who, with their lust for power, ruin the land they inhabit, serving as a dire warning of what comes to pass when stewardly care is corrupted or ignored. Dickerson and Evans examine Tolkien's major works as well as his lesser-known stories and essays, comparing his writing to that of the most important naturalists of the past century. A vital contribution to environmental literature and an essential addition to Tolkien scholarship, Ents, Elves, and Eriador offers both Tolkien fans and environmentalists an understanding of Middle-earth that has profound implications for environmental stewardship in the present and the future of our own world.

Available in PDF, EPUB and Kindle. Book excerpt: Many people fear snakes, and watersnakes in particular have one of the worst reputations of any snake found in North America. Some species are commonly mistaken for venomous cottonmouths, and a few may eat popular game fishes. Unfortunately, few people realize the important roles many watersnakes play in natural ecosystems and, consequently, they are still persecuted in many regions today. Seeking to overcome common misperceptions, J. Whitfield Gibbons and Michael E. Dorcas have compiled North American Watersnakes, the first comprehensive study of all fourteen species of watersnakes found in the United States, Canada, Mexico, and Cuba. Individual species accounts explore all aspects of the natural history of watersnakes in North America, including their behavior, physiology, life history, ecology, and conservation. Almost 100 color photographs accompany the text, illustrating all 14 species and nearly all subspecies. Supplementing the species accounts are detailed color maps depicting each species distribution and stunning black-and-white drawings by Peri Mason. Easy-to-use keys help readers to identify specimens at hand.

Book excerpt: Animal Eyes provides a comparative account of all known types of eye in the animal kingdom, outlining their structure and function with an emphasis on the nature of the optical systems and the physical principles involved in image formation. A universal theme throughout the book is the evolution and taxonomic distribution of each type of eye, and the roles of different eye types in the behaviour and ecology of the animals that possess them. In comparing the specific capabilities of eyes, it considers the factors that lead to good resolution of detail and the ability to function under a wide range of light conditions. This new edition is fully updated throughout, incorporating more than a decade of new discoveries and research.

Available in PDF, EPUB and Kindle. Book excerpt: As industry and technology proliferate in modern society, sustainability has jumped to the forefront of contemporary political and environmental discussions. The balance between progress and the earth's ability to provide for its inhabitants grows increasingly precarious as we attempt to achieve sustainable development. In The Agrarian Vision: Sustainability and Environmental Ethics, Paul B. Thompson articulates a new agrarian philosophy, emphasizing the vital role of agrarianism in modern agricultural practices. Thompson, a highly regarded voice in environmental philosophy, unites concepts of agrarian philosophy, political theory, and environmental ethics to illustrate the importance of creating and maintaining environmentally conscious communities. Thompson describes the evolution of agrarian values in America, following the path blazed by Thomas Jefferson, John Steinbeck, and Wendell Berry. Providing a pragmatic approach to ecological responsibility and commitment, The Agrarian Vision is a significant, compelling argument for the practice of a reconfigured and expanded agrarianism in our efforts to support modern industrialized culture while also preserving the natural world.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: A witty and engrossing look at Los Angeles' urban ecology and the city's place in America's cultural fantasies Earthquakes. Wildfires. Floods. Drought. Tornadoes. Snakes in the sea, mountain lions, and a plague of bees. In this controversial tour de force of scholarship, unsparing vision, and inspired writing, Mike Davis, the author of City of Quartz, revisits Los Angeles as a Book of the Apocalypse theme park. By brilliantly juxtaposing L.A.'s fragile natural ecology with its disastrous environmental and social history, he compellingly shows a city deliberately put in harm's way by land developers, builders, and politicians, even as the incalculable toll of inevitable future catastrophe continues to accumulate. Counterpointing L.A.'s central role in America's fantasy life--the city has been destroyed no less than 138 times in novels and films since 1909--with its wanton denial of its own real history, Davis creates a revelatory kaleidoscope of American fact, imagery, and sensibility. Drawing upon a vast array of sources, Ecology of Fear meticulously captures the nation's violent malaise and desperate social unease at the millennial end of "the American century." With savagely entertaining wit and compassionate rage, this book conducts a devastating reconnaissance of our all-too-likely urban future.

Book excerpt: This comprehensively updated and expanded revision of the successful second edition continues to provide detailed coverage of the ever-growing range of research topics in vision. In Part I, the treatment of visual physiology has been extensively revised with an updated account of retinal processing, a new section explaining the principles of spatial and temporal filtering which underlie discussions in later chapters, and an up-to-date account of the primate visual pathway. Part II contains four largely new chapters which cover recent psychophysical evidence and computational model of early vision: edge detection, perceptual grouping, depth perception, and motion perception. The models discussed are extensively integrated with physiological evidence. All other chapters in Parts II, III, and IV have also been thoroughly updated.

Available in PDF, EPUB and Kindle. Book excerpt: “Lash is capable of explaining the mind-bending concepts of Gnosticism and pagan mystery cults with bracing clarity and startling insight. . . . [His] arguments are often lively and entertaining.”—Los Angeles Times Fully revised and with a new preface by the author, this timely update is perfect for readers of The Immortality Key. Since its initial release to wide acclaim in 2006, Not in His Image has transformed the lives of readers around the world by presenting the living presence of the Wisdom Goddess as never before revealed, illustrating that the truth of an impactful Gnostic message cannot be hidden or destroyed. With clarity, author John Lamb Lash explains how a little-known messianic sect propelled itself into a dominant world power, systematically wiping out the great Gnostic spiritual teachers, the Druid priests, and the shamanistic healers of Europe and North Africa. Early Christians burned libraries and destroyed temples in an attempt to silence the ancient truth-tellers and keep their own secrets. Not in His Image delves deeply into ancient Gnostic writings to reconstruct the story early Christians tried to scrub from the pages of history, exploring the richness of the ancient European Pagan spirituality—the Pagan Mysteries, the Great Goddess, Gnosis, the myths of Sophia and Gaia. In the 15th Anniversary Edition, Lash doubles down on his original argument against redemptive ideology and authoritarian deceit. He shows how the Gnostics clearly foresaw the current program of salvation by syringe, and places the Sophianic vision of life centrally in the battle to expose and oppose the evil agenda of transhumanism, making this well-timed update more relevant than ever. “Sometimes a book changes the world. Not in His Image is such a book. It is clear, stimulating, well-researched, and sure to outrage the experts. . . . Get it. Improve not just your own life, but civilization’s chances for survival.”—Roger Payne, author of Among Whales
