Download or read book Genetic variation patterns of Shorea contorta and Parashorea malaanonan Dipterocarpaceae in the Philippines written by Randy Alfabete Villarin and published by Cuvillier Verlag. This book was released on 2013-04-09 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid decline of the Philippine forests has resulted in highly fragmented tree populations. In response to this, plantation programs boomed during the 80‘s and early 90‘s of the last century. Plantation forests, however, were mostly established with reproductive materials from unknown sources with presumably restricted genetic diversity. In this study, genetic variation patterns at microsatellite (SSR) and AFLP markers were investigated and compared between planted and natural populations of the ecologically important and critically endangered tropical rainforest tree species: Shorea contorta and Parashorea malaanonan (Dipterocarpaceae). The study was important to conserve the remaining genetic diversity within populations of the investigated dipterocarps. Further, it provided useful data for better planning actions when it comes to reinforcement of existing species populations and re-introduction of the species. In addition, it gave information for a genetically sound seed collection efforts to support the continuous forest restoration programs in the country.

An assessment is made of dipterocarp mycorrhizal specificity and a discussion is presented on how mycorrhizal specificity may have contributed to speciation in Dipterocarpaceae. Other aspects touched upon include work on a non- ectomycorrhizal association of a fungus with dipterocarp roots, proposed to be called amphymycorrhizae. Also discussed are the effects of physical influences upon dipterocarp ectomycorrhizae, demonstrating the negative impact of high topsoil temperatures and lack of oxygen upon functioning and survival of dipterocarp ectomycorrhizae. Furthermore how dipterocarp ectomycorrhizae influence regeneration of Dipterocarpaceae through enhanced survival near the mother trees. At the end of the book practical recommendations are given for optimalization of management of mixed dipterocarp forests based upon the conclusions reached in the research, including the use of correct fungus-dipterocarp combinations for different sites.
Download or read book Forest Landscape Restoration written by Stephanie Mansourian and published by Routledge. This book was released on 2018-09-03 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest landscape restoration (FLR) is a planned process that aims to regain ecological integrity and enhance human wellbeing in deforested or degraded landscapes. The aim of this book is to explore options to better integrate the diverse dimensions - spatial, disciplinary, sectoral, and scientific - of implementing FLR. It demonstrates the value of an integrated and interdisciplinary approach to help implement FLR focusing specifically on four issues: understanding the drivers of forest loss and degradation in the context of interdisciplinary responses for FLR; learning from related integrated approaches; governance issues related to FLR as an integrated process; and the management, creation and use of different sources of knowledge in FLR implementation. The emphasis is on recognising the need to take human and institutional factors into consideration, as well as the more obvious biophysical factors. A key aim is to advance and accelerate the practice of FLR, given its importance, particularly in a world facing increasing environmental challenges, notably from climate change. The first section of the book presents the issue from an analytical and problem-orientated viewpoint, while later sections focus on solutions. It will interest researchers and professionals in forestry, ecology, geography, environmental governance and landscape studies.

Download or read book The pollination of cultivated plants A compendium for practitioners written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-10-15 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than twenty years ago, the Food and Agriculture Organization of the United Nations contributed to the growing recognition of the role of pollination in agricultural production, with the publication of “The Pollination of Cultivated Plants in the Tropics”. Since that time, the appreciation of pollinators has grown, alongside the realization that we stand to lose them. But our knowledge and understanding of crop pollination, pollinator biology, and best management practices has also expanded over this time. This volume is the second of two “compendiums for practitioners”, sharing expert knowledge on all dimensions of crop pollination in both temperate and tropical zones. The focus in this second volume is on management, study and research tools and techniques.
