Low Intensity Breeding Of Native Forest Trees In Argentina

Global climate change requires the development of programs that consider the active restoration of degraded forests and the use of native trees in afforestation to preserve the natural environment. International commitments like the UN REDD program, the Montréal Process and the Convention on Biological Diversity call for the breeding of species rarely contemplated by large industrial companies. Low-intensity breeding is the most rational strategy for those species: simple but robust, and not dependent on continuously increasing funding, and therefore effective even with a relatively small budget. It commonly focuses on high genetic diversity rather than improving economic traits and adaptability rather than productivity. Controlled crosses with full pedigrees typical of high-intensity breeding are replaced by open pollination. This book presents state-of-the-art breeding strategies from the last two decades for several forest tree species of prime importance in the natural forests of Argentina. They are distributed in the three main forestry ecoregions of the country: the subtropical dry forest (Chaco), the subtropical rain forests (Yungas and Alto Paraná rainforests) and the temperate forests of Patagonia. The book also discusses the genetic patterns of the selected species defined using genetic markers together with the analysis of the variation in quantitative traits. Further, it examines the crucial features of their reproductive biology, such as the mating system and gene flow and describes the current breeding programs. Lastly, it presents the latest developments in genetic resources and their emerging applications, concluding with some reflections and perspectives related to the conditioning imposed by climate change.

In order to feed the world, global agriculture will have to double food production by 2050. As a result, the use of soils with fertilizers and pesticides in agronomic ecosystems will increase, taking into account the sustainability of these systems and also the provision of food security. Thus, soil ecosystems, their health, and their quality are directly involved in sustainable agronomical practices, and it is important to recognize the important role of soil microbial communities such as mycorrhizal fungi, their biodiversity, interactions, and functioning. Soil ecosystems are under the threat of biodiversity loss due to an increase of cultivated areas and agronomic exploitation intensity. Also, changes in land use alter the structure and function of ecosystems where biodiversity is vital in the ecosystem. Soils are a major aid in food production in all terrestrial ecosystems; however, this means they are also involved in gas emission and global warming. Thus, in agronomic ecosystems, several mitigation practices have been proposed to promote the increase of carbon soil stock, and the reduction of warming gas emission from soils. In South America, most of the rural population depends economically on agriculture and usually works in family units. New, organic, safe, and sustainable agro-forestry practices must be applied to support local communities and countries to achieve hunger eradication, rural poverty reduction, and sustainable development. This book compiles new information for mycorrhizal occurrence in natural and anthropic environments in South America. It includes new reports of mycorrhizal fungi diversity along different mycorrhizal types and their effect on plant communities, plant invasions, the use of mycorrhizal fungi for ecological and sustainable studies, management programs of natural and agroecosystems, and forestry and food-secure production. This book fills the gaps in biodiversity knowledge, management and safe food production of mycorrhizas. It should be a valuable help to researchers, professors and students, to aid in use of mycorrhizal fungi while also focusing on their biodiversity, sustainable safe food production, and conservation perspectives.

Prosopis describes the enormous historical importance of these trees as a human food source and reviews the contemporary food science of the fruit derived from these trees. As well, this treatise reviews the native genetic resources of this genus on 4 continents and classical genetic and horticultural techniques that could help stabilize the environment and alleviate human suffering on some of the world’s most destitute agro-ecosystems. This book is an essential read for researchers interested in forestry and plant science, environmental science, and functional foods. The legume family (Fabaceae) contains many genera and species that through their nitrogen fixing process provide high protein food and feed for humans and animals. As evidenced by its presence in Death Valley, California, which holds the record for the highest temperatures in the world, these types of plants can thrive in extreme environments. Edited by the world’s leading experts on Prospis species with globally recognized contributors Covers the different perspectives surrounding the advantages and disadvantages of planting different Prosopis species Discusses the applications of Prosopis species, including how the fruits of this tree can be used as a raw food material

There are a wide range of biotechnologies available and many of them have been, and are currently being, used in many situations and sectors worldwide to solve the myriad problems that farmers are facing. Documentation of the application of agricultural biotechnologies for smallholders is an important part of FAO’s role in facilitating knowledge sharing regarding agricultural biotechnologies. This document synthesizes a unique series of 15 case studies where agricultural biotechnologies were used to serve the needs of smallholders in developing countries. The introduction chapter provides an overall background and objectives of the compilation of case studies. The case studies cover different regions, production systems, species and underlying socioeconomic conditions in the crop, livestock and aquaculture/fisheries sectors. The biotechnologies covered include some that are considered quite traditional, such as artificial insemination, as well as other more modern ones, such as the use of DNA-based diagnostics. The case studies were prepared by scientists and researchers who were directly involved in the initiatives, and the authors aimed to provide the background, achievements, obstacles, challenges and lessons learned from each case study. The final chapter of the document provides a summary overview of the challenges, results and lessons learned from the 15 case studies.

"This is a book like no other--the only truly comprehensive, one-volume illustrated guide to all of the world's birds, covering the complete International Ornithological Congress World Bird List. Featuring more than 300 stunning large-format, full-color plates, this accessible and authoritative encyclopedic reference presents incredibly detailed, accurate, and beautiful paintings of more than 10,700 species by some of the world's best bird artists, led by the legendary Norman Arlott and Ber van Perlo. In addition, The Complete Birds of the World provides detailed but concise identification information about each species on facing pages--including facts about voice, habitat, and geographic distribution. The result is a visual and verbal feast that captures the astonishing variety of bird life around the planet--and that will be cherished by any birder." -- Amazon.
