Book Synopsis Geographic Variation in Forest Trees by : Maria Morgenstern
Download or read book Geographic Variation in Forest Trees written by Maria Morgenstern and published by UBC Press. This book was released on 2011-11-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geographic Variation in Forest Trees is the first book to examine this subject from a world-wide perspective. The author discusses population genetic theory and genetic systems of native North American tree species as they interact with environments in the major climatic regions in the world. He then demonstrates how this knowledge is used to guide seed zoning and seed transfer in silviculture, basing much of his discussion on models developed in Scandinavia and North America. In the final chapter, the author addresses the issue of genetic conservation -- a subject of great concern in the face of accelerated forest destruction, industrial pollution, and climatic change. This comprehensive, well-researched book makes a significant contribution to the knowledge of one of our most important renewable natural resources.

Book Synopsis Genetic Response of Forest Systems to Changing Environmental Conditions by : Gerhard Müller-Starck
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.
Book Synopsis Introduction to Forest Genetics by : Jonathan Wright
Download or read book Introduction to Forest Genetics written by Jonathan Wright and published by Elsevier. This book was released on 2012-12-02 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Forest Genetics examines some of the basic genetic concepts typically used in forestry and tree improvement studies, including Mendelian and population genetics. It also describes techniques that are generally useful in tree improvement work, including individual tree selection and breeding, provenance testing, species and racial hybridization, and introduction of exotics. Organized into 19 chapters, this volume begins with an overview of forest genetics and problems associated with forest genetics. It then discusses concepts from basic genetics, including chromosome structure and function; DNA and RNA; nongenetic inheritance; and genotype versus phenotype. Other chapters focus on inbreeding: complete elimination of homozygous recessive trees; mutation and migration; and controlled pollination and vegetative propagation. The book also covers the establishment and measurement of test plantations; general principles and methods of selective breeding; choice of breeding method and type of seed orchard; heritability and genetic gain; geographic variation in Scotch pine and American trees; species and racial hybridization; chromosome studies; and polyploidy and haploidy breeding. This book is a valuable resource for foresters, professional tree breeders, and those with or without previous training in genetics or forestry.

Book Synopsis Population Genetics of Forest Trees by : W.T. Adams
Download or read book Population Genetics of Forest Trees written by W.T. Adams and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical climates, which occur between 23°30'N and S latitude (Jacob 1988), encompass a wide variety of plant communities (Hartshorn 1983, 1988), many of which are diverse in their woody floras. Within this geographic region, temperature and the amount and seasonality of rainfall define habitat types (UNESCO 1978). The F AO has estimated that there 1 are about 19 million km of potentially forested area in the global tropics, of which 58% were estimated to still be in closed forest in the mid-1970s (Sommers 1976; UNESCO 1978). Of this potentially forested region, 42% is categorized as dry forest lifezone, 33% is tropical moist forest, and 25% is wet or rain forest (Lugo 1988). The species diversity of these tropical habitats is very high. Raven (1976, in Mooney 1988) estimated that 65% of the 250,000 or more plant species of the earth are found in tropical regions. Of this floristic assemblage, a large fraction are woody species. In the well-collected tropical moist forest of Barro Colorado Island, Panama, 39. 7% (481 of 1212 species) of the native phanerogams are woody, arborescent species (Croat 1978). Another 21. 9% are woody vines and lianas. Southeast Asian Dipterocarp forests may contain 120-200 species of trees per hectare (Whitmore 1984), and recent surveys in upper Amazonia re corded from 89 to 283 woody species ~ 10 cm dbh per hectare (Gentry 1988). Tropical communities thus represent a global woody flora of significant scope.

Book Synopsis Genetic Variation in Blue Spruce by : David F. Van Haverbeke
Download or read book Genetic Variation in Blue Spruce written by David F. Van Haverbeke and published by . This book was released on 1984 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analyses of 43 blue spruce populations at age 12 (9 years in the field) revealed significant differences among populations for survival, height, vigor, crown diameter, frost injury, and foliage color. Use of regions increases the probability of locating better seeds sources, but high variability among individual populations within regions limits their value in specifying where better seed sources can be collected. Phenotypes should be selected in best stands within regions.

Book Synopsis Geographic Variation, Speciation and Clines. (MPB-10), Volume 10 by : John A. Endler
Download or read book Geographic Variation, Speciation and Clines. (MPB-10), Volume 10 written by John A. Endler and published by Princeton University Press. This book was released on 2020-03-31 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geographic Variation, Speciation and Clines explores the origins and development of geographic variation, divergence, and speciation. In particular it is concerned with genetic divergence as it is usually found on continents, among groups of populations isolated only by distance. Although earlier writers on this topic considered the effects of geography and dispersal, intense geographic differentiation and speciation were thought to require complete isolation. Professor Endler shows how geographic differentiation and speciation may develop in spite of continuous gene flow. Following a review of the diverse and scattered literature on gene flow and population differentiation, the author discusses the relationships among gene flow, dispersal, and migration. He then summarizes the factors which limit the geographic extent of gene flow, and those which allow steep clines to develop in the absence of barriers to gene flow. His analysis draws on examples from the field, experiments, and single- and multiple-locus models. The mechanism and conditions for parapatric speciation are presented: steepening clines, development into hybrid zones, and the evolution of sexual isolation. In the final chapter the author considers the interpretation of natural clines and the associated geographic patterns of subspecies and species.
