Book Description
Migrant insect pests represent a constant threat to crops and to health in many parts of the world. In Africa alone, over $100 million is spent annually on the control of a half dozen species of locust. One of the key problems in combating migrant pests is that the insect can disappear for months at a time and reappear with catastrophic effect. With the aid of aircraft and radar, it has been possible to map the movements of migrant pests. The research in this book, carried out on an international scale, has shown that migrant pests can travel longer distances than previously suspected and that their movements are related to the dynamics of the winds and weather systems. These findings throw new light on the flight behavior of the insects as well as on the ecological and evolutionary aspects of flight migration and suggest new options for controlling pests, especially locusts and grasshoppers. In surveying the achievements in this area, the author provides the biologist with an introduction to the relevant aspects of meteorology.

Book Description
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.

Book Description
The reader of this comprehensive presentation benefits from an outstanding overview of all aspects of the fascinating phenomenon of bird migration. The book is written by leading experts from around the world. The text summarizes reviews and discussions of the most recent hypotheses. In doing so, it covers the entire research field from phenomenology through to ecology, physiology, control mechanisms, orientation, evolutionary aspects and conservation measures. It also examines the most modern methodological approaches including, satellite trakcking, molecular techniques or stable isotope investigations and envisages forthcoming developments in the course of global warming.

Book Description
This book consists of a diverse collection of chapters that seeks to broaden our fundamental understanding of the ecological function and biological importance of the Earth’s lower atmosphere, which provides a huge living space for billions of animals moving within and across continents. Their migration, dispersal and foraging activities connect water and land habitats within and across continents. Drawing upon the wide-ranging experience of the authors, the book takes an inherently interdisciplinary approach that serves to introduce the reader to the topic of aeroecology, frame some of the basic biological questions that can be addressed within the context of aeroecology, and highlight several existing and emerging technologies that are being used to promote aeroecological studies. The book begins with several background chapters, that provide introduction into such topics as atmospheric science, the concept of the habitat, animal physiology, and methods of navigation. It then continues with a broad discussion of observational methods available to and used by aeroecologists. Finally, several targeted examples of aeroecological studies are presented. Following the development of the chapters, the reader is provided with a unifying framework for investigating how the dynamic properties of meteorological conditions at local, regional, and global scales affect the organisms that depend on the air for foraging and movement. Material presented in the book should be of interest to anyone wishing to gain a comprehensive understanding of the aerosphere itself and the myriad airborne organisms that inhabit and depend upon this environment for their existence. The material should be accessible to a diverse set of readers at all stages of training and across a range of research expertise.

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
Why did large numbers of Scots leave a temperate climate to live permanently in parts of the world where greater temperature extreme was the norm? The long nineteenth century was a period consistently cooler than now, and Scotland remains the coldest of the British nations. Nineteenth-century meteorologists turned to environmental determinism to explain the persistence of agricultural shortage and to identify the atmospheric conditions that exacerbated the incidence of death and disease in the towns. In these cases, the logic of emigration and the benefits of an alternative climate were compelling. Emigration agents portrayed their favoured climate in order to pull migrants in their direction. The climate reasons, pressures and incentives that resulted in the movement of people have been neither straightforward nor uniform. There are known structural features that contextualize the migration experience, chief among them being economic and demographic factors. By building on the work of historical climatologists, and the availability of long-run climate data, for the first time the emigration history of Scotland is examined through the lens of the nation’s climate. In significant per capita numbers, the Scots left the cold country behind; yet the ‘homeland’ remained an unbreakable connection for the diaspora.
