Book Description
Plant response to climate change can occur through a variety of mechanisms including population migration and phenotypic evolution. The effects of migration are often preserved in genetic patterns of contemporary forests, and can include genetic drift during population fragmentation as well as genetic bottlenecks during founder events. Besides migration, populations often change phenotypically in response to shifting climates. In this study I quantify genetic and morphological patterns of central and western North American white spruce populations. Specifically I have (1) provided evidence supporting Hulten's long standing hypothesis that ice-free areas of Beringia served as northern refugia for arctic and boreal biota during the last Quaternary glaciation using cpDNA markers, (2) provided evidence for multiple refugia in Alaska and uncovered the roles of gene flow and drift in structuring the patterns we see today and (3) teased apart the controlling mechanisms behind morphological expression (genetics, environment, or genetic x environmental interactions) in traits by comparing needle morphologies of common garden and naturally grown individuals.

Genetic Variation in Blue Spruce
Author: David F. Van Haverbeke
Publisher:
ISBN:
Category : Spruce
Languages : en
Pages : 12
Book Description
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.

The Conifers: Genomes, Variation and Evolution
Author: David B. Neale
Publisher: Springer
ISBN: 3319468073
Category : Science
Languages : en
Pages : 590
Book Description
This book is the first comprehensive volume on conifers detailing their genomes, variations, and evolution. The book begins with general information about conifers such as taxonomy, geography, reproduction, life history, and social and economic importance. Then topics discussed include the full genome sequence, complex traits, phenotypic and genetic variations, landscape genomics, and forest health and conservation. This book also synthesizes the research included to provide a bigger picture and suggest an evolutionary trajectory. As a large plant family, conifers are an important part of economic botany. The group includes the pines, spruces, firs, larches, yews, junipers, cedars, cypresses, and sequoias. Of the phylum Coniferophyta, conifers typically bear cones and evergreen leaves. Recently, there has been much data available in conifer genomics with the publication of several crop and non-crop genome sequences. In addition to their economic importance, conifers are an important habitat for humans and animals, especially in developing parts of the world. The application of genomics for improving the productivity of conifer crops holds great promise to help provide resources for the most needy in the world.
