This book brings together information on the contrasting characteristics, condition, present use and problems of the world's main natural grasslands. Since grassland is commercialized through the grazing animal, particular attention is paid to the livestock production systems associated with each main type. Grazing resources are more than simply edible herbage: many other factors have to be taken into account, notably water in all areas, and shelter in winter-cold climates. Seasonality of forage supply is a characteristic of almost all grazing lands, so the strategies for dealing with lean seasons are described. The main problems of each type are mentioned and possible strategies for their sustainable management discussed - taking into account their multiple functions, not only livestock production. The book is primarily aimed at agricultural scientists, educationalists, extensionists and decision-makers with interests in responsible use of extensive grasslands.

This multi-authored volume contains peer-reviewed chapters from leading researchers and professionals in silvopastoral systems topic in Southern South America (Argentina, Chile and South Brazil). It is a compendium of original research articles, case studies, and regional overviews and summarizes the current state of knowledge on different components and aspects (pasture production, animal production, trees production, carbon sequestration, conservation) of silvopatoral systems in native forests and tree plantations. The main hypothesis of the book is that farmers have integrated tree and pasture/grassland species in their land use systems to reach higher production per unit of land area, risk avoidance, product diversification, and sustainability. These production systems also impact positively in main ecosystem processes. Management of these productive systems, Policy and Socioeconomic Aspects provide great opportunities and challenges for farmers and policy makers in our region. The book is unique on this subject in Southern South America and constitutes a valuable reference material for graduate students, professors, scientists and extensionists who work with silvopastoral systems.

The Freshwaters of Patagonia adopts a socioecological approach, in which experts from across Patagonia review recent, scientifically rigorous literature and data of their own, thus synthesizing the current knowledge directly relevant to understand the present state and future trends of icefields, freshwater and wetland ecosystems in this region. The book’s organization into three parts provides a studied and comprehensive view on the patterns and processes of the various ecosystems in Patagonia, and describes the sociological aspects of freshwater ecosystems, as well as characterizes the conservation of the freshwater and wetland ecosystems, in Patagonia. The chapters offer a broad, state-of-the-art overview of the current status of glaciers, freshwater and wetland ecosystems of this region, as well as studies of both local and large scale biodiversity patterns, and study cases of extreme and naturally polluted environments.The volume concludes with the current status of Patagonian freshwaters, and discusses the scientific, legal and administrative tools aimed at their sustainable management within the framework of the UNEP Sustainable Development Goals 2030 Agenda. A broad audience of students, scientists, engineers, environmental managers, and policy makers will be interested in this volume.

Organic animal production has increased rapidly in recent years to keep up with the increasing consumer demand for organic meats. There are many guidelines and restrictions on what should go into the feedstuffs of organically farmed animals, from which difficulties arise when trying to ensure a well-balanced, nutritious diet without the use of any supplements. The book has been completely updated and revised to address how to formulate organic diets in situations where there is a declining supply of organic feed, as well as the feasibility of utilizing novel feedstuffs and their acceptability by consumers of organic meat products. Including the experiences of producers in relation to appropriate breeds and production systems for forage-based organic production, this book is an important read for researchers and students of organic food animal production, veterinary sciences and food; as well as food industry personnel and organic farmers.

Rock art in South America is as diverse as the continent itself. In this vast territory, different peoples produced engravings, paintings, and massive earthworks, from the Atacama to the Amazon. These marks on the landscape were made by all different kinds of peoples, from some of the earliest hunter-gatherers in the continent, to the very complex societies within the Inca Empire. This book brings together the work of specialists from throughout the continent, addressing this diversity, as well as the variety of approaches that the Archaeology of rock art has taken in South America. Constructed of eleven thought-provoking chapters and arranged in three thematic sections, the book presents different theoretical approaches that are currently being used to understand the roles rock art played in prehistoric communities. The editors have skillfully crafted a book that presents the contribution the study of South American rock art can offer to the global research of this materiality, both theoretically and methodologically. This book will interest a broad range of scholars researching in archaeology, anthropology, history of art, heritage and conservation, as well as undergraduate and postgraduate students who will find interesting case studies showcasing the diverse ways in which rock art can be approached. Despite its focus on South America, the book is intended as a contribution towards the global study of rock art.

Latin America is a megadiverse territory hosting several hotspots of plant diversity and many types of forest biomes, ecosystems and climate types, from tropical rainforest to semi-arid woodlands. This combination of diverse forests and climates generates multiple responses to ecological changes affecting the structure and functioning of forest ecosystems. Recently, there have been major efforts to improve our understanding of such impacts on ecosystems processes. However, there is a dearth of studies focused on Latin-American forest ecosystems that could provide novel insights into the patterns and mechanisms of ecological processes in response to environmental stress. The abundance of “New World” tree species with dendrochronological potential constitutes an ideal opportunity to improve the ecological state of knowledge regarding these diverse forest types, which are often threatened by several impacts such as logging or conversion to agricultural lands. Thus, detailed information on the dendroecology of these species will improve our understanding of forests in the face of global change. Accordingly, this book identifies numerous relevant ecological processes and scales, ranging from tree species to populations and communities, and from both dendrochronological and dendroecological perspectives. It offers a valuable reference guide for the exploration of long-term ecological interactions between trees and their environmental conditions, and will foster further research and international projects on the continent and elsewhere.

This book presents contributions devoted to the hydrogeochemical characterization of aquatic environments of Patagonia, including those of Ushuaia city, known as "The southernmost city in the world". Patagonia (between 39° and 55° S) is located in southern South America. Eight main river systems pour their waters into the SW Atlantic Ocean. Rivers, with their headwaters mainly located in the Andes, supply dissolved and particulate matter to the coastal zone, as well as nutrients, which benefit biological communities. Besides, freshwater in this region with little anthropogenic impact supports human life and a high wildlife biodiversity. Unfortunately, the recent increase in human activities, such as the use of fertilizers, wastewater discharges, extensive deforestation and dam construction, is affecting the quality and quantity of water resources. The book is of interest for researchers, professors and government agencies that decide on water resources management policies.

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.
