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.

Download or read book Biopesticides in Environment and Food Security Issues and Strategies written by Opender Koul and published by Scientific Publishers. This book was released on 2012-06-01 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drivers behind food security and crop protection issues vis-à-vis the food losses caused by pests include rapid human population increase, climate change, loss of beneficial on-farm biodiversity, reduction in per capita cropped land, water shortages, and pesticide withdrawals. Integrated pest management, therefore, becomes a compulsory strategy in agriculture, which offers a 'toolbox' of complementary crop- and region-specific crop protection solutions to address these rising pressures. IPM aims at more sustainable solutions by using complementary technologies and one of them is the use of biopesticides including genetically modified cropping systems. The aim is to reduce pests below economic thresholds utilizing key 'ecological services', particularly biocontrol systems via semiochemicals, biopesticides, precision pest monitoring tools, and rapid diagnostics. In fact, we are facing twin problems of environment and food security for the expanding population and it is necessary to ensure adequate pesticide-free food. The ecofriendly nature of biopesticide products suggests environment protection and safety for natural enemies and non-target organisms. However, their adoption and use have lagged behind due to certain constraints like variable performance under field situations, lack of quality standards and interest by big industrial houses, and cumbersome regulatory procedures. The present book is an attempt to critically debate over all these issues and suggest a road map for future.

Download or read book Agroclimatology written by Jerry L. Hatfield and published by John Wiley & Sons. This book was released on 2020-01-22 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: Can we unlock resilience to climate stress by better understanding linkages between the environment and biological systems? Agroclimatology allows us to explore how different processes determine plant response to climate and how climate drives the distribution of crops and their productivity. Editors Jerry L. Hatfield, Mannava V.K. Sivakumar, and John H. Prueger have taken a comprehensive view of agroclimatology to assist and challenge researchers in this important area of study. Major themes include: principles of energy exchange and climatology, understanding climate change and agriculture, linkages of specific biological systems to climatology, the context of pests and diseases, methods of agroclimatology, and the application of agroclimatic principles to problem-solving in agriculture.

Available in PDF, EPUB and Kindle. Book excerpt: Insects provide excellent model systems for understanding evolutionary ecology. They are abundant, small, and relatively easy to rear, and these traits facilitate both field and laboratory experiments. This book has been developed from the Royal Entomological Society's 22nd international symposium, held in Reading in 2003. Topics include speciation and adaptation; life history, phenotype plasticity and genetics; sexual selection and reproductive biology; insect-plant interactions; insect-natural enemy interactions; and social insects.

Download or read book Aeroecology written by Phillip B. Chilson and published by Springer. This book was released on 2018-03-23 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
