Download or read book Ecosystem Ecology Research Trends written by Junying Chen and published by Nova Publishers. This book was released on 2008 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecosystem ecology is the integrated study of biotic and abiotic components of ecosystems and their interactions within an ecosystem framework. This science examines how ecosystems work and relates this to their components such as chemicals, bedrock, soil, plants, and animals. A major focus of ecosystem ecology is on functional processes, ecological mechanisms that maintain the structure and services produced by ecosystems. These include primary productivity (production of biomass), decomposition, and trophic interactions. Studies of ecosystem function have greatly improved human understanding of sustainable production of forage, fibre, fuel, and provision of water. Functional processes are mediated by regional-to-local level climate, disturbance, and management thus ecosystem ecology provides a powerful framework for identifying ecological mechanisms that interact with global environmental problems, especially global warming and degradation of surface water. This book presents the latest developments in the field from around the world.
Download or read book Ecology and Conservation of Tropical Ungulates in Latin America written by Sonia Gallina-Tessaro and published by Springer Nature. This book was released on 2019-11-20 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together the latest information on tropical ungulates in different Latin American countries. These animals are not only important from the point of view of their role in different ecosystems, but also have cultural value for people. The book also discusses topics such as habitat transformation and hunting as these species are an important source of food in many places. Addressing ungulate natural communities in diverse ecosystems and countries, the book provides information on specific aspects of each of the most representative species, and highlights topics to help readers better understand these species and develop effective management and conservation strategies. The information presented also reveals the need for more knowledge and will hopefully provide the incentive for continued studies on this important group of animals. This publication serves as a reference for academic research on ungulate ecology, behavior and dynamics, as well as the basis for conservation strategies.
Download or read book Historical Biogeography of Neotropical Freshwater Fishes written by James S. Albert and published by Univ of California Press. This book was released on 2011-03-08 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fish faunas of continental South and Central America constitute one of the greatest concentrations of aquatic diversity on Earth, consisting of about 10 percent of all living vertebrate species. Historical Biogeography of Neotropical Freshwater Fishes explores the evolutionary origins of this unique ecosystem. The chapters address central themes in the study of tropical biodiversity: why is the Amazon basin home to so many distinct evolutionary lineages? What roles do ecological specialization, speciation, and extinction play in the formation of regional assemblages? How do dispersal barriers contribute to isolation and diversification? Focusing on whole faunas rather than individual taxonomic groups, this volume shows that the area’s high regional diversity is not the result of recent diversification in lowland tropical rainforests. Rather, it is the product of species accumulating over tens of millions of years and across a continental arena.

Download or read book Biogeography of the Quaternary Molluscs of the Southwestern Atlantic Ocean written by Sergio Martínez and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Quaternary comprises a brief time in the Earth’s history, and apart from a few exceptions, molluscan assemblages recovered from exposures along the coast of Southwestern South America (Southern Brazil, Uruguay, Argentina) are essentially the same than those that inhabit the region today, leading to the assumption that no important change in the distribution of the faunas since Pleistocene times has occurred. However, the good taxonomic and temporal resolution reached in the last years, allowed us to detect some biogeographic changes, although traditional biogeographic units remain the same (i.e. Magellanic and Argentinean Provinces). These modifications involve mainly variations in the taxonomic composition of the assemblages and in the southern boundaries of some species distributions (extralimital species), today retracted northwards. These changes are related to southward shifts of the warm waters of the Brazilian Current, correlated with global warm peaks. This phenomenon was more intense in the Late Pleistocene (MIS 5e) and in the Holocene between ca. 6500-3500 14C yr.

Download or read book River Science written by David J. Gilvear and published by John Wiley & Sons. This book was released on 2016-05-02 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: River Science is a rapidly developing interdisciplinary field at the interface of the natural sciences, engineering and socio-political sciences. It recognises that the sustainable management of contemporary rivers will increasingly require new ways of characterising them to enable engagement with the diverse range of stakeholders. This volume represents the outcome of research by many of the authors and their colleagues over the last 40 years and demonstrates the integral role that River Science now plays in underpinning our understanding of the functioning of natural ecosystems, and how societal demands and historic changes have affected these systems. The book will inform academics, policy makers and society in general of the benefits of healthy functioning riverine systems, and will increase awareness of the wide range of ecosystem goods and services they provide.

Download or read book Ichnology of the Lowlands of South America written by José Herminio Laza and published by Springer Nature. This book was released on 2020-12-16 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ichnology is the science of marks, tracks, trails, traces structures and other sources of evidence of biological activity, beyond the living beings themselves, when studied both in continents and oceans. In spite of its scientific value and interdisciplinary contribution, particularly in South America, in the complex task of identifying ancient environments, information is dispersed and sometimes even ignored. This book has recovered the remarkably abundant information that Ichnology of terrestrial environments has incorporated. The studied geographical regions are the Pampas of Argentina, vast lowlands with a wide latitudinal distribution in between the warm and wet subtropical areas and the cold deserts of Patagonia. Pedogenetic processes preserve tracks and marks found in sediments, rock surfaces and soils, revealing the activity of life forms. This book refers to a variety of signs of biological activity, particularly in ancient soils. This volume includes abundant original information and a meticulous revision of paleo-ichnological investigations, most by the author himself, one of the most important South American specialists, during many decades of his dedication to scientific research. The book includes a review of the stratigraphic sequences of the Cenozoic chronostratigraphic scheme. Firstly, the author provides a scrutiny of the continental ichnofacies and the ichnological record of the South American Cenozoic age. This is followed by chapters dedicated to the faunal associations of vertebrates, with very valuable information about the past climatic events and biogeographical changes, of undoubted value for those scholars interested in vertebrate Paleontology. Likewise, the highly relevant ichnotaxonomy is also developed exhaustively, with special reference to the essential activity of insects in the paleosols, mostly ants and termites. /divFinally, this book presents the most complete, extensive and up-dated bibliography in the subject, which is probably unique as such for southern South America and most of the world. Certainly, this is a book that will provide valuable scientific tools for those specialists interested in this infrequent discipline, either paleontologists, biologists, geologists, pedologists and sedimentologists.
