Book Description
Many of the world's most serious agricultural pests are highly migratory. Through the use of special-purpose radars we are provided with insights into their movement and how they learn about and navigate through their environment. This text examines the behaviour and regional variations of these species, as well as the altitude of migration, concentration of insects in layers and how they respond to large and small-scale wind systems. The book relates radar observation of insect movement to complementary and competing methodologies and surveys its capabilities and limitations. It also deals wi

Book Description
This volume is an outgrowth of a Symposium entitled "Evolution of Escape in Space and Time" held at the XV International Congress of Entomology in Washington, D. C., USA in August, 1976. The choice of topic was prompted by recent advances in evolutionary ecology and the apparent suitability of insect migration and dia pause as appropriate material for evolutionary studies. In the event, that choice seems amply justified as I hope a perusal of these papers will show. These Sympos ium papers hardly cover the topic of the evolution of escape mechanisms exhaustively, and I am sure everyone will have his favorite lacuna. Some of the more obvious ones are indicated by Professor Southwood in his Concluding Remarks at the end of the book. The purpose of the Symposium, however, was not complete coverage, but rather to indicate the potential inherent in insect migration and diapause for the study of evolutionary problems. In that I think we have succeeded reasonably well. These papers are expanded and in some cases somewhat altered versions of the papers delivered in Washington. This has allowed greater coverage of the topics in question. I suggested a format of a general overview of a topic emphasizing the author's own research con tributions. In general the papers follow this outline although emphases vary. Two of the authors, Dr. Rainey and Dr. Lumme, were unable to attend the Symposium. Dr. Rainey's paper was read by Mr. Frank Walsh, but Dr.

Book Description
Tiny ruby-throated hummingbirds weighing less than a nickel fly from the upper Midwest to Costa Rica every fall, crossing the six-hundred-mile Gulf of Mexico without a single stop. One of the many creatures that commute on the Mississippi Flyway as part of an annual migration, they pass along Chicago’s lakefront and through midwestern backyards on a path used by their species for millennia. This magnificent migrational dance takes place every year in Chicagoland, yet it is often missed by the region’s two-legged residents. The Art of Migration uncovers these extraordinary patterns that play out over the seasons. Readers are introduced to over two hundred of the birds and insects that traverse regions from the edge of Lake Superior to Lake Michigan and to the rivers that flow into the Mississippi. As the only artist in residence at the Field Museum, Peggy Macnamara has a unique vantage point for studying these patterns and capturing their distinctive traits. Her magnificent watercolor illustrations capture flocks, movement, and species-specific details. The illustrations are accompanied by text from museum staff and include details such as natural histories, notable features for identification, behavior, and how species have adapted to environmental changes. The book follows a gentle seasonal sequence and includes chapters on studying migration, artist’s notes on illustrating wildlife, and tips on the best ways to watch for birds and insects in the Chicago area. A perfect balance of science and art, The Art of Migration will prompt us to marvel anew at the remarkable spectacle going on around us.

Book Description
"This timely book reveals how the increase in traffic of transpacific plants, insects, and peoples raised fears of a "biological yellow peril" beginning in the late nineteenth century, when mass quantities of nursery stock and other agricultural products were shipped from large, corporate nurseries in Japan to meet the growing demand for exotics in the United States. Jeannie Shinozuka marshals extensive research to explain how the categories of "native" and "invasive" defined groups as bio-invasions that must be regulated-or somehow annihilated-during a period of American empire-building. Shinozuka shows how the modern fixation on foreign species provided a linguistic and conceptual arsenal for anti-immigration movements that gained ground in the early twentieth century. Xenophobia fed concerns about biodiversity, and in turn facilitated the implementation of plant quarantine measures while also valuing, and devaluing, certain species over others. The emergence and rise of economic entomology and plant pathology alongside public health and anti-immigration movements was not merely coincidental. Ultimately, what this book unearths is that the inhumane and unjust incarceration of Japanese Americans during World War II cannot, and should not, be disentangled from this longer history"--

Book Description
Knowledge of insect movement, particularly of flight, is crucial to our understanding of the great ecological and evolutionary success of insects. The last 20 years have seen many advances in this subject area. New fields have arisen, such as metapopulation theory, and dramatic developments have taken place in methods of studying movement, as a result of new techniques in molecular biology and radar monitoring. There have also been advances in our knowledge of flight-related physiology and behaviour. This book, which is based on the main papers presented at the Royal Entomological Society's 20th Symposium held in September 1999, brings us up to date with these developments.It contains chapters on:flight mechanismsforaging movementsmigrationthe evolution of movement strategiesthe interactions between dispersal rates, population structure and gene flow the effects of climate change on geographical distributionIt is essential reading for entomologists, and of interest to those researching animal behaviour, physiology, ecology and genetics.

Book Description
Monarch butterflies are among the most popular insect species in the world and are an icon for conservation groups and environmental education programs. Monarch caterpillars and adults are easily recognizable as welcome visitors to gardens in North America and beyond, and their spectacular migration in eastern North America (from breeding locations in Canada and the United States to overwintering sites in Mexico) has captured the imagination of the public. Monarch migration, behavior, and chemical ecology have been studied for decades. Yet many aspects of monarch biology have come to light in only the past few years. These aspects include questions regarding large-scale trends in monarch population sizes, monarch interactions with pathogens and insect predators, and monarch molecular genetics and large-scale evolution. A growing number of current research findings build on the observations of citizen scientists, who monitor monarch migration, reproduction, survival, and disease. Monarchs face new threats from humans as they navigate a changing landscape marked by deforestation, pesticides, genetically modified crops, and a changing climate, all of which place the future of monarchs and their amazing migration in peril. To meet the demand for a timely synthesis of monarch biology, conservation and outreach, Monarchs in a Changing World summarizes recent developments in scientific research, highlights challenges and responses to threats to monarch conservation, and showcases the many ways that monarchs are used in citizen science programs, outreach, and education. It examines issues pertaining to the eastern and western North American migratory populations, as well as to monarchs in South America, the Pacific and Caribbean Islands, and Europe. The target audience includes entomologists, population biologists, conservation policymakers, and K–12 teachers.
