Radar Entomology
Author: V. Alistair Drake
Publisher: CABI
ISBN: 9781845936068
Category : Entomology
Languages : en
Pages : 489
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

The Biomechanics of Insect Flight
Author: Robert Dudley
Publisher: Princeton University Press
ISBN: 0691186340
Category : Science
Languages : en
Pages : 497
Book Description
From the rain forests of Borneo to the tenements of Manhattan, winged insects are a conspicuous and abundant feature of life on earth. Here, Robert Dudley presents the first comprehensive explanation of how insects fly. The author relates the biomechanics of flight to insect ecology and evolution in a major new work of synthesis. The book begins with an overview of insect flight biomechanics. Dudley explains insect morphology, wing motions, aerodynamics, flight energetics, and flight metabolism within a modern phylogenetic setting. Drawing on biomechanical principles, he describes and evaluates flight behavior and the limits to flight performance. The author then takes the next step by developing evolutionary explanations of insect flight. He analyzes the origins of flight in insects, the roles of natural and sexual selection in determining how insects fly, and the relationship between flight and insect size, pollination, predation, dispersal, and migration. Dudley ranges widely--from basic aerodynamics to muscle physiology and swarming behavior--but his focus is the explanation of functional design from evolutionary and ecological perspectives. The importance of flight in the lives of insects has long been recognized but never systematically evaluated. This book addresses that shortcoming. Robert Dudley provides an introduction to insect flight that will be welcomed by students and researchers in biomechanics, entomology, evolution, ecology, and behavior.

Experimental Analysis of Insect Behaviour
Author: L.B. Browne
Publisher: Springer Science & Business Media
ISBN: 3642866662
Category : Science
Languages : en
Pages : 376
Book Description
This volume has come about as a direct result of a Symposium entitled "Experimental Analysis of Insect Behaviour" which was an important con tribution to the 14 International Congress of Entomology held in Canberra, Australia, in August 1972 under the joint sponsorship of the Australian Academy of Science and the Australian Entomological Society. It is not, however, strictly Symposium proceedings. I have included, in this volume contributions from several workers who had to withdraw from the Symposium at a fairly late stage. Furthermore, quite intentionally, a number of the contributions bear only a general relationship to the papers given at the Congress. To permit this; the deadline for contribu tions was set at some six months after the Symposium. I imposed no restrictions on the form of the contributions. I did, however, indicate that speculative reviews highlighting the author's own recent research or that of his immediate colleagues would be particularly acceptable, and a number of the contributors have taken the opportunity to write this kind of paper. Several contributors, notably those whose task it was to give more general papers in the Symposium itself, have written reviews of somewhat greater scope.

Insect Movement
Author: Ian Woiwood
Publisher: CABI
ISBN: 9780851997810
Category : Electronic books
Languages : en
Pages : 490
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.

The Ecology of Reproduction in Wild and Domestic Mammals

ISBN: 9401165270
Category : Science
Languages : en
Pages : 318
Book Description
49 about six months ... to well over a year. If there is only one part of the year that is favourable, such as spring and early summer in the temperate climates, then each species must make an evolutionary choice, so to speak, as to which parts of the reproductive cycle - conception, gestation, lactation or weanin- must be protected and which can come in less favourable times of the year. The rhesus and langur monkeys of northern India give birth during the time of year when temperatures are hottest and wells and tanks are often dry. However, gestation and the later months oflactation come during the monsoon season when food and water are abundant. In contrast the east African baboons give birth at the beginning of the small rains, and gestation and the late part of lactation occur during the six months dry season. Whether any pattern of relationship will be found to hold true for other species of primates is still not clear. It may be that a wide variety of patterns have evolved depending on the lengths of gestation and lactation and the particular ecological complex in which each species or even subspecies lives' (pages 503, 504).

Evolution and Adaptation of Terrestrial Arthropods
Author: John L. Cloudsley-Thompson
Publisher: Springer Science & Business Media
ISBN: 3642613608
Category : Science
Languages : en
Pages : 149
Book Description
This book is intended as a textbook for 3rd year undergraduate students, as well as postgraduate students. It comprises a review of the current opinion regarding the evolution and adaptation of terrestrial arthropods, beginning with the paleontological, embryological, morphological and physiological evidence. The implication of size is then considered in relation to life on land. A discussion of insect phylogeny and the origin of flight is followed by an account of evolutionary trends in reproduction. Further chapters cover adaptations to extreme environments, dispersal and migration, defensive mechanisms and, finally, present arguments for the success of the terrestrial arthropods in general.
