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.

Download or read book Forest Conservation Genetics written by Andrew Young and published by CSIRO PUBLISHING. This book was released on 2000-07-24 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest management must be sustainable not only in ecological, economic and social, but also genetic terms. Many forest managers are advocating and developing management strategies that give priority to conserving genetic diversity within production systems, or that recognise the importance of genetic considerations in achieving sustainable management. Forest Conservation Genetics draws together much previously uncollected information relevant to managing and conserving forests. The content emphasises the importance of conserving genetic diversity in achieving sustainable management. Each chapter is written by a leading expert and has been peer reviewed. Readers without a background in genetics will find the logical sequence of topics allows easy understanding of the principles involved and how those principles may impact on day-to-day forest planning and management decisions. The book is primarily aimed at undergraduate students of biology, ecology, forestry, and graduate students of forest genetics, resource management policy and/or conservation biology. It will prove useful for those teaching courses in these fields and as such help to increase the awareness of genetic factors in conservation and sustainable management, in both temperate and tropical regions.

Download or read book Genetics Genomics and Breeding of Conifers written by Christophe Plomion and published by CRC Press. This book was released on 2011-08-10 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 their domestication. Topics include cytogenetics, patterns of nucleotide diversity, genetic mapping, integration of molecular markers in breeding, transcriptomics, advances in proteomics and metabolomics in gymnosperms, and economic importance.

Download or read book Genetics and Conservation of Rare Plants written by Donald A. Falk and published by Oxford University Press. This book was released on 1991-11-14 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly 700 species of plants may become extinct by the year 2000. Faced with this overwhelming prospect, plant conservationists must take advantage of every technique available. This unique work summarizes our current knowledge of the genetics and population biology of rare plants, and integrates it with practical conservation recommendations. It features discussions on the distribution and significance of genetic variation, management and evaluation of rare plant germplasm, and conservation strategies for genetic diversity. Case studies focusing on specific problems offer important insights for today's challenges in rare plant conservation.

This book was released on 1995 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Forest Genetic Resources Centre held a workshop to address issues relevant to the conservation and management of Canada's forest genetic resources. The workshop included presentations highlighting the current status of conservation efforts and ideas and strategies for optimal in-situ and ex-situ conservation of forest genetic resources. Working group discussions were a major component of the workshop and were aimed at identifying gaps in current conservation efforts, conservation priorities, research initiatives to support conservation priorities, and promoting opportunities for increased collaborative efforts. A major output of the workshop was the development of a framework for a national strategy to focus on the sound management of Canada's forest genetic resources. This report presents the workshop proceedings, including the contributed papers on forest genetic conservation.
