Taschenbuch. Condizione: Neu. Neuware - 'Weather and Climate in Their Relation to Insects' is an essential scientific study that investigates the profound impact of meteorological factors and climatic shifts on insect biology and populations. Written by the pioneering entomologist B. P. Uvarov, this work systematically explores how environmental variables-including temperature, moisture, solar radiation, and wind-influence the physiological processes and life cycles of various insect species. The text provides a detailed examination of how climate dictates the geographical distribution, migration, and seasonal activities of insects. Uvarov draws upon extensive research to illustrate the complex relationship between atmospheric conditions and the survival strategies of insects, offering critical insights into how weather patterns can trigger mass outbreaks or lead to population declines. By synthesizing biological observations with meteorological data, the work establishes a foundational framework for understanding the ecological dynamics of the natural world. This comprehensive volume is a vital resource for scholars and practitioners in the fields of entomology, ecology, and environmental science. 'Weather and Climate in Their Relation to Insects' remains a significant contribution to the study of terrestrial ecosystems, emphasizing the intricate ties between the atmosphere and the animal kingdom.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Taschenbuch. Condizione: Neu. Neuware - 'Locusts and Grasshoppers: A Handbook for Their Study and Control' is a comprehensive and seminal scientific work by B. P. Uvarov, focusing on the biology, behavior, and management of these significant agricultural pests. As a cornerstone text in the field of entomology, this handbook provides detailed insights into the life cycles, anatomy, and ecological impact of various species of Acrididae. Uvarov, a leading authority on the subject, explores the complex phenomena of phase transformation-where solitary grasshoppers transition into swarming locusts-and the environmental factors that trigger these devastating outbreaks.The work meticulously catalogs diverse species across the globe, offering practical guidance on identification and monitoring. Beyond theoretical study, it serves as a practical manual for control strategies, detailing historical and then-modern techniques for mitigating the destruction caused to crops and vegetation. This volume is an invaluable resource for entomologists, agriculturalists, and natural historians, reflecting the scientific rigor and systematic observation required to address one of humanity's oldest agricultural challenges. Its detailed illustrations and data-driven approach underscore the importance of international cooperation in pest management.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Cloth. Condizione: Good. A few charts and diagrams throughout, pp 247; (88), first page a little marked and stained, otherwise clean and sound internally. Neatly and sturdily bound in blue cloth, very slightly marked and faded. ["Boris Uvarov's researches on taxonomy, morphology, biometrics and behaviour of locusts led him to formulate the phase theory respecting those insects, greatly influencing locus research throughout the world. It has also provided a basis for international policy of prevention of locust outbreaks. His studies of outbreaks in Africa contributed much towards establishing correlation between seasonal weather conditions and locus migrations thus providing a basis for forecasting. Other work includes over 150 papers on taxonomy of Orthoptera and many on Orthopterous faunas. Has also done much to encourage locust research and played a leading part in planning international anti-locus measures.".…
