Download or read book Mechanisms and Deployment of Resistance in Trees to Insects written by Michael R. Wagner and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanisms and Deployment of Resistance in Trees to Insects is a worldwide synthesis of tree resistance to insects. The contributions are by senior scientists and represent all the major forested regions of the world. The book constitutes a comprehensive treatment of the state of our knowledge on patterns of resistance by insect guilds and how this knowledge can be deployed to achieve the management of damaging forest insects. This book will serve as an essential reference book for all researchers and practitioners attempting to manage forest pests using genetic resistance.
Download or read book Developing Sitka Spruce Populations for Resistance to the White Pine Weevil written by John Norman King and published by . This book was released on 2009 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reports on the results of over two decades of research in the Sitka Spruce Breeding Program. The objective of the Sitka spruce (Picea sitchensis [Bong.] Carr.) breeding program is to develop, propagate, and deploy genotypes with robust resistance to the white pine weevil (Pissodes strobe Peck).
Download or read book Ecology and Management of Sitka Spruce written by N. Merle Peterson and published by UBC Press. This book was released on 2011-11-01 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sitka spruce, the largest of the world's spruces, is an important component of British Columbia's coastal forests. Its ecology gives it a special place in the sustainable management of the province's forests. However, in west coast forestry it is poorly known in comparison with its main coniferous companions -- Douglas-fir, western redcedar, and western hemlock. As an important international forestry resource, it is crucial that Sitka spruce -- its ecology and the ecosystems in which it occurs -- be clearly understood by those who are involved with its management.
Download or read book The White Pine Weevil written by British Columbia. Ministry of Forests and published by . This book was released on 1994 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: The white pine weevil, Pissodes strobi Peck, can be found in nearly all regions of Canada and the U.S. It causes severe deformity and growth losses by damaging a tree's leader, which results in reduction of merchantable wood volume. These attacks threaten Sitka spruce plantings by the forest industry in B.C. In eastern Canada it limits the planting of eastern white pine and spruce. The goals of the White Pine Weevil Workshop were to consolidate current scientific knowledge and to map out a strategy for future research and funding requirements. 33 papers were presented on weevil research and management including biology and damage; genetics, weevils and hosts; and silviculture and control.
Download or read book Genetic Response of Forest Systems to Changing Environmental Conditions written by Gerhard Müller-Starck and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changing environmental conditions substantially affect genetic variation and its dynamics in forest ecosystems and various systems of plantations. In response to these challenges, the present book focuses on the response to stress in terms of case studies which address physiological and genetic characters as well as various metric traits. Furthermore a choice of studies is presented which refers to diversity and geographic variation of various species and site conditions, respectively. In addition, genetic resources are characterised and a variety of studies is compiled which address reproduction and migration as well as management aspects. Finally, a set of studies is presented which focus on forest tree breeding with respect to uncertain climatic futures.
