This book was released on 2012-12-06 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects are by far the largest group of animals on Earth, with over a million described species, and they occupy a wide range of ecological niches - they may be herbivores, predators, parasites or decomposers. Some are of particular economic importance as pests of agriculture and forestry, as vectors of animal and human disease, or as species of interest to wildlife conservation. Thus an understanding of the processes determining their numbers is of considerable practical value. Entomologists have played a leading role in developing a theoretical basis to Population Ecology, but we still do not have adequate experimental and observational proof for many of the theoretical ideas that have been proposed. As a result, the subject has been beset with arguments for more than 50 years. This volume attempts to reconcile some of these controversies, while also reviewing the current state of our knowledge. The editors have drawn together an international list of contributors whose views reflect a range of opinions on how natural populations are stabilised. They have succeeded in producing a book that both covers the main alternative views in population theory and contains some of the best recent field studies of insect populations. This Royal Entomological Society Symposium volume will be of great interest to all entomologists and ecologists, particularly those who wish to know more about Population Dynamics.

This book was released on 2013-06-29 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects multiply. Destruction reigns. There is dismay, followed by outcry, and demands to Authority. Authority remembers its experts or appoints some: they ought to know. The experts advise a Cure. The Cure can be almost anything: holy water from Mecca, a Government Commis sion, a culture of bacteria, poison, prayers denunciatory or tactful, a new god, a trap, a Pied Piper. The Cures have only one thing in common: with a little patience they always work. They have never been known entirely to fail. Likewise they have never been known to prevent the next outbreak. For the cycle of abundance and scarcity has a rhythm of its own, and the Cures are applied just when the plague of insects is going to abate through its own loss of momentum. -Abridged, with insects in place of voles, from C. Elton, 1924, Voles, Mice and Lemmings, with permission of Oxford University Press This book is an enquiry into the "natural rhythms" of insect abundance in forested ecosystems and into the forces that give rise to these rhythms. Forests form unique environ ments for such studies because one can find them growing under relatively natural (pri meval) conditions as well as under the domination of human actions. Also, the slow growth and turnover rates of forested ecosystems enable us to investigate insect popula tion dynamics in a plant environment that remains relatively constant or changes only slowly, this in contrast to agricultural systems, where change is often drastic and frequent.

Book excerpt: This book consisting of ten review chapters contributed by leading workers in their respective fields, from around the world, covers the whole subject of insect reproduction.It begins with the basic physiological questions of insect reproduction, moves on to discuss the new advances seen in the fields of behavioural and ecological mechanisms, and culminates by examining the recent work on evolutionary biology and its application in the field. Each chapter, although including a brief review of the basic seminal work, focuses mainly on the advances made within the last ten years and highlights those areas in which the respective authors see the greatest scope for further important advances
Download or read book Insects a Very Short Introduction written by Simon R. Leather and published by Oxford University Press. This book was released on 2022-03-03 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects are a fascinatingly diverse and beautiful group of animals. They are found on all continents, in caves, underground, inside other insects, in rivers, lakes, puddles, and in our houses. To date, over a million insect species have been named. In this Very Short Introduction, Simon Leather explores insects' evolution, behaviour, and development, highlighting their pivotal role in supporting ecosystems across the planet. He considers the threats of environmental change, including climate change, to insects globally and the potentially catastrophic impact of insect population declines.
