Download or read book Radar Entomology written by V. Alistair Drake and published by CABI. This book was released on 2012 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book (10 chapters) covers radar entomology and its application in the study and monitoring of insect flight and migration. Chapter 1 provides a general introduction to both radar and the biological phenomena that entomologists have studied with radars. An outline of alternative and complementary methods for studying insect movement and a brief historical account of developments in the field are included. Chapter 2 introduces the fundamentals of remote sensing and briefly summarizes some entomological applications of it that do not involve radio technology. The technique and theory underlying radar entomology are covered in chapters 3-8, whereas the principal biological findings that have resulted from the use of radar technology are discussed in chapters 9-14. This book is intended primarily for entomologists, although this publication may also be useful to behaviourists, ecologists, biometeorologists, radar ornithologists and radar meteorologists.

This book was released on 1975 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of radar to detect and monitor weather phenomena and to detect and control aircraft are well known, but relative few radar technicians and operators realize the importance of radar for detection of birds. The information in this report, presented in handbook form, was obtained from radar operated by the National Weather Service and the FAA. The techniques and information presented should aid radar operators in recognizing the various types of echoes from birds displayed on weather and air-traffic control radars, in estimating the numbers of birds passing over the radar stations, and in gathering information on the altitude of the birds aloft. Use of this information and techniques should be of great assistance in reducing the number of bird/aircraft collisions and improve flight safety.

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

This book was released on 1996-01-18 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Migration is one of the most fascinating and dramatic of all animal behaviors. Historically, however, the study of migration has been fragmented, with ornithologists, entomologists, and marine biologists paying little attention to work outside their own fields. This treatment of the subject shows how comparisons across taxa can in fact illuminate migratory life cycles and the relation of migration to other movements. The book thus takes an integrated ecological perspective, focusing on migration as a biological phenomenon. The work is divided into four parts, each with a brief introductory section. Part I defines migration, gives examples, and places migration in the spectrum of movement behaviors, concluding with a chapter on methods for its study. Part II focuses on proximate mechanisms, including physiology and morphology (and the constraints associated with them), the interactions between migration and wind and current patterns, and the various orientation and navigation mechanisms by which migrants find their way about. Part III on the evolution of migratory life histories addresses the evolutionary and ecological basis for migration and the roles of migration not only in the lives of organisms, but also in the ecological communities in which they live. Part IV is devoted to a brief consideration of migration and its relation to pest management and conservation. As a major contribution to a vital subject, this work will be valued by all researchers and students in the field of animal behavior, ecology, and zoology.

This book was released on 2014-04-04 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present and over the next few years, large-scale windfarms are being installed far off the coast of Germany in the North and Baltic Sea, making a major contribution to electricity generation from renewable energy sources. One of the German government’s aims is to ensure the environmentally sound and sustainable development of offshore wind energy. Germany’s first offshore test site, alpha ventus, was therefore accompanied from the construction phase to the first years of operation by an intensive environmental research programme, the StUKplus project, financed by the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety and coordinated by the Federal Maritime and Hydrographic Agency. Marine and ecological aspects have been researched there for more than five years to improve the level of knowledge about the ecological impacts of offshore windfarms. This book provides a broad, richly illustrated overview of applied and new research methods and monitoring techniques. It summarises the key research findings on the impacts on benthic communities, fish, marine mammals and birds, also taking into account underwater sound and sediment measurements. Interpreting the results in the sense of lessons learned, new challenges and perspectives are discussed for future sustainable offshore development in German waters.

Available in PDF, EPUB and Kindle. Book excerpt: “Rigorous and well defended . . . Faaborg makes many fresh and, in some cases, provocative points regarding management guidelines for migrant birds.” —Kenneth Able, Great Plains Research In the 1980s, numerous scientific surveys documented both declining bird populations, especially among Neotropical songbirds that winter in the tropics, and the loss of tropical rain forest habitat. Drawing the seemingly obvious conclusion, scientists and environmental activists linked songbird declines to loss of tropical habitats and alerted the world to an impending ecological catastrophe. Their warnings led to the establishment of the Neotropical Migratory Bird Conservation Program, also known as Partners in Flight, the self-proclaimed largest conservation effort in history. Looking back over more than a decade of efforts to save migrant birds, John Faaborg offers the first serious evaluation of the state of songbird populations today, the effectiveness of conservation programs such as Partners in Flight, and the reliability and completeness of scientific research on migrant birds. Taking neither an alarmist nor a complacent approach, he shows that many factors besides habitat loss affect bird populations and that Neotropical migrants as a group are not declining dramatically, though some species adapt to habitat alteration more successfully than others. Faaborg’s state-of-the-art survey thus clarifies the kinds of information we will need and the conservation efforts we should undertake to ensure the long-term survival of Neotropical migrant birds. “Presents a carefully and closely reasoned argument about the magnitude of the conservation problems facing migrant birds, how we can reduce these problems, and how current conservation efforts have enormous value even if there is no immediate crisis.” —Scott K. Robinson, Professor and Head, Department of Animal Biology, University of Illinois

Available in PDF, EPUB and Kindle. Book excerpt: E. GWINNER! The phenomenon of bird migration with its large scale dimensions has attracted the attention of naturalists for centuries. Worldwide billions of birds leave their breeding grounds every autumn to migrate to areas with seasonally more favor able conditions. Many of these migrants travel only over a few hundred kilo meters but others cover distances equivalent to the circumference of the earth. Among these long-distance migrants are several billion birds that invade Africa every autumn from their West and Central Palaearctic breeding areas. In the Americas and in Asia the scope of bird migration is of a similar magnitude. Just as impressive as the numbers of birds are their achievements. They have to cope with the enormous energetic costs of long-distance flying. particularly while crossing oceans and deserts that do not allow replenishment of depleted fat reserves. They have to appropriately time the onset and end of migrations. both on a daily and annual basis. And finally. they have to orient their migratory movements in space to reach their species- or population-specific wintering and breeding grounds, irrespective of the variable climatic conditions along their migratory routes.

This book was released on 2021-03-30 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: New York Times Bestseller Finalist for the Los Angeles Times Book Prize A Library Journal Best Science and Technology Book of the Year An exhilarating exploration of the science and wonder of global bird migration. In the past two decades, our understanding of the navigational and physiological feats that enable birds to cross immense oceans, fly above the highest mountains, or remain in unbroken flight for months at a stretch has exploded. What we’ve learned of these key migrations—how billions of birds circumnavigate the globe, flying tens of thousands of miles between hemispheres on an annual basis—is nothing short of extraordinary. Bird migration entails almost unfathomable endurance, like a sparrow-sized sandpiper that will fly nonstop from Canada to Venezuela—the equivalent of running 126 consecutive marathons without food, water, or rest—avoiding dehydration by "drinking" moisture from its own muscles and organs, while orienting itself using the earth’s magnetic field through a form of quantum entanglement that made Einstein queasy. Crossing the Pacific Ocean in nine days of nonstop flight, as some birds do, leaves little time for sleep, but migrants can put half their brains to sleep for a few seconds at a time, alternating sides—and their reaction time actually improves. These and other revelations convey both the wonder of bird migration and its global sweep, from the mudflats of the Yellow Sea in China to the remote mountains of northeastern India to the dusty hills of southern Cyprus. This breathtaking work of nature writing from Pulitzer Prize finalist Scott Weidensaul also introduces readers to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges. Drawing on his own extensive fieldwork, in A World on the Wing Weidensaul unveils with dazzling prose the miracle of nature taking place over our heads.
