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.
With contributions by internationally reputed researchers in the field, this book presents the implications of the genomic revolution for conifers-promoting a better understanding of the evolution of these organisms as well as new knowledge about the molecular basis of quantitative trait variation. Both of these discoveries play important roles in
Dothistroma pini changed New Zealand commercial forestry dramatically. Tree breeding became concentrated on a very few species and development of selection methods and breeding strategies changed in response to the new challenges. Tree-Breeding and Genetics in New Zealand provides a critical historical account of the work on provenance research and tree breeding, often with the wisdom of hindsight, and it tracks the development of breeding strategy, especially for P. radiata, Douglas-fir and the most important eucalypt species, E. regnans, E. fastigata and E. nitens. The book is a compendium of abstracts and summaries of all publications and reports on tree improvement in New Zealand since the early 1950s, with added critical comment by the author on much of the work. It is intended for other tree breeders internationally, for interested NZ foresters and for graduate students studying genetics and tree breeding.
During the 4th International Consultation on Forest Genetics and Tree Building, held in 1998 in Beijing, China, leading scientists were invited to review past achievements, to redefine the role of forest genetics and breeding in contemporary forestry, and to set priorities for future research and development. On the basis of the invited presentations, the volume summarizes the state of knowledge in various fields, such as the impact of forest management and of changing environmental conditions on genetic resources, and the value of genetic markers as indicators for adaptational potential, as well as the tasks of conservation. Detailed reports from the different continents provide a comprehensive diagnosis of the global situation of forest genetics and tree breeding research. The book offers not only an overview of contemporary trends and expected future developments, but also identifies current main problems in funding and cooperation. It may prove therefore useful not only for scientists, university lecturers and advanced students in the field of forestry, ecology and conservation biology, but also for decision makers and managers in companies and conservation organizations.
In The Whale and the Supercomputer, scientists and natives wrestle with our changing climate in the land where it has hit first--and hardest A traditional Eskimo whale-hunting party races to shore near Barrow, Alaska--their comrades trapped on a floe drifting out to sea--as ice that should be solid this time of year gives way. Elsewhere, a team of scientists transverses the tundra, sleeping in tents, surviving on frozen chocolate, and measuring the snow every ten kilometers in a quest to understand the effects of albedo, the snow's reflective ability to cool the earth beneath it. Climate change isn't an abstraction in the far North. It is a reality that has already dramatically altered daily life, especially that of the native peoples who still live largely off the land and sea. Because nature shows her footprints so plainly here, the region is also a lure for scientists intent on comprehending the complexities of climate change. In this gripping account, Charles Wohlforth follows the two groups as they navigate a radically shifting landscape. The scientists attempt to decipher its smallest elements and to derive from them a set of abstract laws and models. The natives draw on uncannily accurate traditional knowledge, borne of long experience living close to the land. Even as they see the same things-a Native elder watches weather coming through too fast to predict; a climatologist notes an increased frequency of cyclonic systems-the two cultures struggle to reconcile their vastly different ways of comprehending the environment. With grace, clarity, and a sense of adventure, Wohlforth--a lifelong Alaskan--illuminates both ways of seeing a world in flux, and in the process, helps us to navigate a way forward as climate change reaches us all.
