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

A Handbook on Biotelemetry and Radio Tracking presents the proceedings of an International Conference on Telemetry and Radio Tracking in Biology and Medicine, held in The University of Oxford, Oxford, U.K. on March 20–22, 1979. This book illustrates the advances connected with every aspect of biotelemetry and radio tracking. Organized into five parts encompassing 101 chapters, this compilation of papers begins with an overview of the method that allows assessment or control of biological parameters from animals, subjects, and patients with comparatively little disturbance and restraint. This text then examines radio telemetry as a system for telemetry or communications over great distances. Other chapters consider better transmitter design and construction of radio tracking. This book discusses as well telemetric measurements of hemodynamic response to driving in coronary patients. The final chapter deals with the study of the coastal movements of Atlantic salmon tagged with ultrasonic transmitters. This book is a valuable resource for biological researchers and ecologists.
