Genetic Variation and Seed Zones of Douglas-Fir in the Siskiyou National Forest (Classic Reprint)
Author: Robert K. Campbell
Publisher: Forgotten Books
ISBN: 9780331359800
Category :
Languages : en
Pages : 34
Book Description
Excerpt from Genetic Variation and Seed Zones of Douglas-Fir in the Siskiyou National Forest Because of the range in elevations and the diversity in climate and vegetation within the region, the Forest has been partitioned into six breeding blocks, each including 460-meter and 305-meter elevational bands. This translates into 22 units that must be considered in breeding plans. There is uncertainty whether this number is justified by adaptational or other constraints, and larger blocks would greatly decrease the costs of breeding and increase the benefits. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books. Find more at www.forgottenbooks.com This book is a reproduction of an important historical work. Forgotten Books uses state-of-the-art technology to digitally reconstruct the work, preserving the original format whilst repairing imperfections present in the aged copy.

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.

Silvicultural Research and the Evolution of Forest Practices in the Douglas-fir Region
Author:
Publisher:
ISBN:
Category : Douglas fir
Languages : en
Pages : 176
Book Description
Silvicultural practices in the Douglas-fir region evolved through a combination of formal research, observation, and practical experience of forest managers and silviculturists, and changing economic and social factors. This process began more than a century ago and still continues. It has had a great influence on the economic well-being of the region and on the present characteristics of the regions forests. This long history is unknown to most of the public, and much of it is unfamiliar to many natural resource specialists outside (and even within) the field of silviculture. We trace the history of how we got where we are today and the contribution of silvicultural research to the evolution of forest practices. We give special attention to the large body of information developed in the first half of the past century that is becoming increasingly unfamiliar to both operational foresters andperhaps more importantlyto those engaged in forestry research. We also discuss some current trends in silviculture and silviculture-related research.
