This book reviews all major models and hypotheses concerning the mechanisms supposed to underlie the process of navigation in vertebrates. It covers data on all major model groups of vertebrates studied in the context of animal navigation, such as migratory birds, homing pigeons, sea turtles, subterranean mammals and some migratory fish species. Some other – less studied – groups, e.g., whales, have also been touched. The first part of the book describes different sources of navigational information, with their specific navigational mechanisms known or supposed to be employed by animals for navigational goals. The second part discusses possible functions of these mechanisms in different vertebrates and in the context of different navigational tasks, ranging from short-range navigation, often performed by animals within as small an area as several square meters, to long-distance global-scale migrations performed by many birds and some sea turtles during their lifespan.
Animal Migration, Orientation, and Navigation presents the various aspects of animal migration, including the evolution of migration, climatic and meteorological influences, and bioenergetics. This book discusses the physiological control, sensory systems, orientation and navigation, and biological clocks and phenology aspects of animal migration. Organized into five chapters, this book begins with an overview of the migration strategies of animals in the context of a space continuum. This text then explains the influence of short- and long-term climatic cycles on the spectrum of migratory patterns in nature. Other chapters consider the energetic requirements of different migration strategies and the energy stores of the migrants. This book discusses as well the physiological basis of animal migration, with emphasis on endocrinal findings on the timing and energetic aspects of different migration strategies. The final chapter deals with the mechanisms used in direction finding by migrating animals. This book is a valuable resource for biologists and ecologists.
Biological effects of magnetic fields have been studied in many animals and plants. The magnetic fields were of a wide intensity range and, as alternating fields, of a wide frequency range and of a variety of impulse shapes. Effects on the cellular level, on bio chemical processes, growth and development, interactions with physiology, sensory input, reflexes and rhythm control, to name just a few, have been reported. Numerous magnetically induced changes in behavior have also been described. Recently, the amount of literature covering biological effects of magnetic fields has been rapidly increasing. By now it has grown to such an extent that it can no longer be covered in one volume. Most reviews specialize and focus on particular aspects and/or types of fields or effects. For example, the book edited by MARET et al. (1986) gives an overview on biological effects of steady magnetic fields, MISAKIAN et al. (1993) reviewed those of extremely low frequency magnetic fields, focusing on in vitro effects. BERN HARD (1992) reported on 'electromagnetic smog' in view of pos sible effects on human health and well-being, and a series of papers edited by AMEMIYA (1994) summarizes Japanese research on effects of electromagnetic fields ranging from extern ely low to ultra-high frequencies. TENFORDE (1979) and ADEY (1981) sum marized and discussed tissue interactions, REITER (1993a) neu roendocrine and neurochemical changes associated with various kinds of electromagnetic fields. The book edited by KIRSCHVINK et al.
P. Berthold and E. Gwinnd Bird migration is an intriguing aspect of the living world - so much so that it has been investigated for as long, and as thoroughly, as almost any other natural phenomenon. Aristotle, who can count as the founder of scientific ornithology, paid very close attention to the migrations of the birds he ob served, but it was not until the reign of Friedrich II, in the first half of the 13th century, that reliable data began to be obtained. From then on, the data base grew rapidly. Systematic studies of bird migration were introduced when the Vogelwarte Rossitten was founded, as the first ornithological biological observation station in the world (see first chapter "In Memory of Vogelwarte Rossitten"). This area later received enormous impetus when ex perimental research on the subject was begun: the large-scale bird-ringing experiment initiated in Rossitten in 1903 by Johannes Thienemann (who was inspired by the pioneering studies of C. C. M. Mortensen), the experiments on photoperiodicity carried out by William Rowan in the 1920s in Canada and retention and release experiments performed by Thienemann in the 1930s in Rossitten, the first experimental study on the orientation of migratory birds. After the Second World War, migration research, while continuing in the previous areas, also expanded into new directions such as radar ornithology, ecophysiology and hormonal control mechanisms, studies of evolution, ge netics, telemetry and others.
“Just astonishing . . . Our natural navigational capacities are no match for those of the supernavigators in this eye-opening book.”—Frans de Waal, The New York Times Book Review Publisher's note: Supernavigators was published in the UK under the title Incredible Journeys. Animals plainly know where they’re going, but how they know has remained a stubborn mystery—until now. Supernavigators is a globe-trotting voyage of discovery alongside astounding animals of every stripe: dung beetles that steer by the Milky Way, box jellyfish that can see above the water (with a few of their twenty-four eyes), sea turtles that sense Earth’s magnetic field, and many more. David Barrie consults animal behaviorists and Nobel Prize–winning scientists to catch us up on the cutting edge of animal intelligence—revealing these wonders in a whole new light.
Movement, dispersal, and migration on land, in the air, and in water, are pervading features of animal life. They are performed by a huge variety of organisms, from the smallest protozoans to the largest whales, and can extend over widely different distance scales, from the microscopic to global. Integrating the study of movement, dispersal, and migration is crucial for a detailed understanding of the spatial scale of adaptation, and for analysing the consequences of landscape and climate change as well as of invasive species. This novel book adopts a broad, cross-taxonomic approach to animal movement across both temporal and spatial scales, addressing how and why animals move, and in what ways they differ in their locomotion and navigation performance. Written by an integrated team of leading researchers, the book synthesizes our current knowledge of the genetics of movement, including gene flow and local adaptations, whilst providing a future perspective on how patterns of animal migration may change over time together with their potential evolutionary consequences. Novel technologies for tracking the movement of organisms across scales are also discussed, ranging from satellite devices for tracking global migrations to nanotechnology that can follow animals only a millimetre in size. Animal Movement Across Scales is particularly suitable for graduate level students taking courses in spatial animal ecology, animal migration, and 'movement ecology', as well as providing a source of fresh ideas and opinions for those already active within the field. It will also be of interest and use to a broader audience of professional biologists interested in animal movements and migrations.
From the New York Times-bestselling author of The Secret World of Weather and The Lost Art of Reading Nature’s Signs, learn to tap into nature and notice the hidden clues all around you Before GPS, before the compass, and even before cartography, humankind was navigating. Now this singular guide helps us rediscover what our ancestors long understood—that a windswept tree, the depth of a puddle, or a trill of birdsong can help us find our way, if we know what to look and listen for. Adventurer and navigation expert Tristan Gooley unlocks the directional clues hidden in the sun, moon, stars, clouds, weather patterns, lengthening shadows, changing tides, plant growth, and the habits of wildlife. Rich with navigational anecdotes collected across ages, continents, and cultures, The Natural Navigator will help keep you on course and open your eyes to the wonders, large and small, of the natural world.
