Download or read book Population Genetics in Forestry written by Hans-Rolf Gregorius and published by Springer Science & Business Media. This book was released on 2013-03-13 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: When we consider the main object of forestry, the tree, it immediately becomes clear why experimental population geneticists have been so hesitant in making this object a primary concern of their research. Trees are very long-living organisms with generation intervals frequently exceeding those of their investigators by multiples. They virtually exclude, therefore, application of the classical methods of population genetics since these are based on observing genetic structures over generations. This situation, where the limits set to observation are so severe, particularly requires close cooperation between theory and experiment. It also requires careful consideration of results obtained for organisms other than trees, in order to gain additional insights by comparing the results for trees with those for other organisms. Yet, the greatest challenge to population and ecological genetics probably originates from the fact that forests are very likely to be the most complex ecosystems of all, even in some cases where they are subject to intense management. This complexity, which equally comprises biotic and abiotic factors varying both in time and space, makes extremely high demands on the adaptational capacity and thus flexibility of the carriers of such an ecosystem. Longevity combined with immobility during the vegetative phase, however, appears to contradict the obvious necessity of adaptational flexibility in forest tree populations when compared with short lived and/or mobile organisms.

Download or read book Methods for Estimating Gamete Contributions to Orchard Seed Crops and Vegetative Lots in British Columbia written by Jack Herbert Woods and published by . This book was released on 2005 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods are described for estimating male and female gamete contributions from parent trees to conifer orchard seedlots1 and to vegetative lots in British Columbia. Methods are also described for estimating male gamete contributions for species and locations where contamination from non-orchard pollen is considered significant, and for calculating seedlot statistics when combining separate seedlots. These methods support the Chief Forester Standards for Seed Use (the Standards), developed under the Forest and Range Practices Act of British Columbia. For orchard seedlots and for vegetative lots, estimates of effective population size and genetic worth must be determined in accordance with formulae provided in the Standards. These formulae require male and female gamete contributions to be estimated for each parent tree, and from nonorchard pollen. The Standards refer to "generally accepted scientific methodology" for the estimation of male and female gamete contributions to orchard seedlots. This paper defines generally accepted methods. A number of methods are described and formulae provided for estimating male and female gamete contributions to seed and vegetative lots. Methods vary by expected precision and by application cost. Seed orchard managers should choose the method that best meets their needs.

Available in PDF, EPUB and Kindle. Book excerpt: Clonal forestry has come of age. Basic techniques in genetics and biotechnology of other organisms are generally applicable to forest trees. However, there are some differences, in particular in the juvenile- and maturation-related regeneration. Examined here are crucial topics of juvenility, maturation and rejuvenation in clonal propagation of trees. In addition, the genetics of clones, population biology of clonal deployment, propagation and field testing of clones, clone identification, clonal physiology, regeneration and variation in plant tissue cultures, the role of somatic embryogenesis in clonal forestry, and recent developments in biotechnology, including the molecular structure of trees and gene transfer are covered in depth.

This book was released on 2011-06-29 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of trees live and grow all around us, and we all recognize the vital role they play in the world’s ecosystems. Publicity campaigns exhort us to plant yet more. Yet until recently comparatively little was known about the root causes of the physical changes that attend their growth. Since trees typically increase in size by three to four orders of magnitude in their journey to maturity, this gap in our knowledge has been a crucial issue to address. Here at last is a synthesis of the current state of our knowledge about both the causes and consequences of ontogenetic changes in key features of tree structure and function. During their ontogeny, trees undergo numerous changes in their physiological function, the structure and mechanical properties of their wood, and overall architecture and allometry. This book examines the central interplay between these changes and tree size and age. It also explores the impact these changes can have, at the level of the individual tree, on the emerging characteristics of forest ecosystems at various stages of their development. The analysis offers an explanation for the importance of discriminating between the varied physical properties arising from the nexus of size and age, as well as highlighting the implications these ontogenetic changes have for commercial forestry and climate change. This important and timely summation of our knowledge base in this area, written by highly respected researchers, will be of huge interest, not only to researchers, but also to forest managers and silviculturists.
