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.

Download or read book Moths of Western North America written by Jerry A. Powell and published by Univ of California Press. This book was released on 2009-05-27 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects boast incredible diversity, and this book treats an important component of the western insect biota that has not been summarized before—moths and their plant relationships. There are about 8,000 named species of moths in our region, and although most are unnoticed by the public, many attract attention when their larvae create economic damage: eating holes in woolens, infesting stored foods, boring into apples, damaging crops and garden plants, or defoliating forests. In contrast to previous North American moth books, this volume discusses and illustrates about 25% of the species in every family, including the tiny species, making this the most comprehensive volume in its field. With this approach it provides access to microlepidoptera study for biologists as well as amateur collectors. About 2,500 species are described and illustrated, including virtually all moths of economic importance, summarizing their morphology, taxonomy, adult behavior, larval biology, and life cycles.
