Download or read book Amazonia Landscape and Species Evolution written by Carina Hoorn and published by John Wiley & Sons. This book was released on 2011-09-26 with total page 869 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book focuses on geological history as the critical factor in determining the present biodiversity and landscapes of Amazonia. The different driving mechanisms for landscape evolution are explored by reviewing the history of the Amazonian Craton, the associated sedimentary basins, and the role of mountain uplift and climate change. This book provdes an insight into the Meso- and Cenozoic record of Amazonia that was characterized by fluvial and long-lived lake systems and a highly diverse flora and fauna. This fauna includes giants such as the ca. 12 m long caiman Purussaurus, but also a varied fish fauna and fragile molluscs, whilst fossil pollen and spores form relics of ancestral swamps and rainforests. Finally, a review the molecular datasets of the modern Amazonian rainforest and aquatic ecosystem, discussing the possible relations between the origin of Amazonian species diversity and the palaeogeographic, palaeoclimatic and palaeoenvironmental evolution of northern South America. The multidisciplinary approach in evaluating the history of Amazonia has resulted in a comprehensive volume that provides novel insights into the evolution of this region.

Download or read book Water and Society II written by C.A. Brebbia and published by WIT Press. This book was released on 2013-09-04 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Containing the proceedings of the Second International Conference on the title topic, the book examines issues related to the nature of water, and its use and exploitation by society. Since ensuring an adequate water supply is becoming a critical issue in more and more countries, the conference brings together specialists from the social sciences and humanistic disciplines and the physical and natural sciences, biology, environmental sciences, and health to bridge gaps between the disciplines in addressing the problem. The international, interdisciplinary nature of the conference participants makes it possible to arrive at equitable solutions to the many transnational issues, relating to the rights of states, which arise around water supply.The book discusses: The nature of water; Water as a human right; Water as the source of life; Water in a changing climate; Future water demands and adaptation strategies; Water resources contamination; Water resources management; Irrigation and desertification; Water, sanitation and health; Transnational water rights; Legislation and controls; Lessons to be learnt; Water and disaster management.

Download or read book Nukak written by Gustavo Politis and published by Taylor & Francis. This book was released on 2016-09-17 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: From Gustavo Politis, one of the most renowned South American archaeologists, comes the first in-depth study in English of the last “undiscovered” people of the Amazon. His work is groundbreaking and urgent, both because of encroaching guerrilla violence that makes Nukak existence perilously fragile, and because his work with the Nukak represented one of the last opportunities to conduct research with hunter-gatherers using contemporary methodological and the theoretical tools. Through a rich and comprehensive ethno-archaeological portrait of material culture “in the making,” this work makes methodological and conceptual advances in the interpretation of hunter-gather societies. Politis’s conclusions, based on six years of original research and on comparative analysis, are integrative and contribute to the identification of the multiple factors involved in the formation of hunter-gatherer archaeological assemblages.

Download or read book Mycorrhizal Fungi in South America written by Mónica A. Lugo and published by Springer Nature. This book was released on 2022-10-27 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2018-09-17 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildlife management is the focus of considerable international debate because of its importance for biodiversity conservation, human safety, livelihoods and food security. Local people have been managing wildlife for millennia, including through hunting. Sufficient examples are presented in this edition to show that sustainable wildlife management is also feasible in the modern era. In some cases, a sustainable offtake – by local people, trophy hunters and legitimate wildlife traders – is provin g vital to obtain local buy-in to wildlife management and to pay the costs of maintaining habitats. No doubt the debate will continue on the best ways to manage wildlife; this edition of Unasylva is a contribution to that.
