This book was released on 2010-03 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of people around the world depend on highly productive floodplain rivers for food and recreational fishing. The São Francisco River, a river drainage southeast of the Amazon River, has a major fisheries on migratory fishes that crashed in the 1990s. Many believe that the fisheries collapse was due to a lack of floods. However, the dependence of São Francisco River migratory fishes on floods is poorly understood. In this book, we present scientific-based data to aid in understanding the life history of migratory fishes, particularly in relation to floods. We radio-tracked two species to characterize their migrations and spawning. We also monitored radio-tagged fish movements to test the hypothesis that the cool hypolimnetic discharge from Três Marias Dam blocked their upriver migration. Further, we used ichthyoplankton sampling of fishes, and hydrological, and economic data to develop a conceptual model for supplemental water releases from the Três Marias Reservoir to restore successful spawning and the downstream fisheries. The contents of this book will be of interest to fish biologist, fisheries managers, and graduate students.

Book Synopsis The Hydro-geomorphology of the Middle Araguaia River by : Katherine Blom Lininger
Download or read book The Hydro-geomorphology of the Middle Araguaia River written by Katherine Blom Lininger and published by . This book was released on 2013 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Located in central Brazil, the Araguaia River is the largest river flowing through the Cerrado, the Brazilian savanna. The thesis presented here assesses the hydro-geomorphology of the middle Araguaia River-floodplain system by characterizing flooding patterns and linking these patterns to the geomorphology of the floodplain. It also determines the response of floodplain lake morphometry and surface water connectivity to the annual flooding of the river, and describes how different floodplain geomorphologic units influence changes in open water areas in the floodplain from the dry season to the wet season. Peak discharges along the middle Araguaia River can be reduced downstream despite large increases in drainage area and the contribution of tributary inputs. After analyzing average daily discharge measurements from 1975 to 2007 along an upstream reach and a downstream reach in the middle Araguaia River, four main flooding types are characterized based on the magnitude of the peak discharge and the pattern of peak discharge reduction that occurs as the flood wave moves downstream. Short-term losses of channel discharge during the flooding peak and over the flooding season from November to May are estimated, with the downstream reach displaying more short-term channel loss compared to the upstream study reach. Differences in floodplain geomorphological characteristics between the two study reaches, including the proportions of distinct geomorphologic units (a lower elevation impeded floodplain, a unit dominated by paleomeanders, and a unit of accreted banks and islands), influence the patterns of peak reduction and channel loss. Short-term losses of channel discharge during flooding peaks are usually re-gained by the channel by the end of the flooding season, although in two years about 10% of the volume input into the downstream reach was lost from the channel over the flooding season. Using satellite imagery and an open water index, changes in lake area, perimeter, and surface water connectivity with the main channel between dry season and the wet season are determined for 32 floodplain lakes. The changes in lake morphometry and connectivity are linked to how fluvial processes formed the floodplain lakes. Spatial variations in the floodplain areas that became open water from the dry season to the wet season demonstrate that distinct floodplain geomorphologic units influence the extent and location of open water areas during flooding. Floodplain lakes that expand in area and in depth and are connected to the river channel via surface water likely provide storage areas for the channel losses and peak discharge reductions observed in some of the flooding types for the middle Araguaia River. Although there have been attempts to plan the placement of dams on the Araguaia River, the river is not impounded, allowing for the analysis of a river system with an unaltered flow regime. This thesis contributes to knowledge of a large and understudied tropical river in an ecologically sensitive region.

Download or read book Risky Rivers written by Michael Chibnik and published by University of Arizona Press. This book was released on 1994-01-01 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: While anthropologists and ecologists have carefully described the activities of the slash-and-burn cultivators, ranchers, and miners of tropical South America, they have largely overlooked the economic strategies and political struggles of riverine people who survive by flood-recession agriculture and fishing. These ribere_os, who constitute the majority of the inhabitants of the Amazonian floodplains of Peru, have developed ecologically sustainable resource management practices that enable them to cope with periodic inundations of their fields by "risky rivers." They have, however, suffered greatly from unpredictable crop prices and erratic state agricultural policies. Michael Chibnik here examines the household economies, cultural ecology, grassroots political organizations of ribere_os living in three floodplain villages near Iquitos, Peru. He describes the villagers' remarkable history, their participation in misconceived development programs, and their longstanding conflicts with regional elites. Chibnik discusses the political ecology of the region in the context of arguments about appropriate development policies in tropical lowlands. Although ribere_os practice intensive agriculture with low environmental impact, they have not been able to improve their economic circumstances in recent years. Chibnik's study is a significant and timely contribution to current debates about the possibility of sustainable, equitable development in Amazonia.
Book Synopsis Rivers: A Very Short Introduction by : Nick Middleton
Download or read book Rivers: A Very Short Introduction written by Nick Middleton and published by Oxford University Press. This book was released on 2012-04-26 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rivers have played an extraordinarily important role in creating the world in which we live. They create landscapes and provide water to people, plants and animals, nourishing both town and country. The flow of rivers has enthused poets and painters, explorers and pilgrims. Rivers have acted as cradles for civilization and agents of disaster; a river may be a barrier or a highway, it can bear trade and sediment, culture and conflict. A river may inspire or it may terrify. This Very Short Introduction is a celebration of rivers in all their diversity. Nick Middleton covers a wide and eclectic range of river-based themes, from physical geography to mythology, to industrial history and literary criticism. Worshipped and revered, respected and feared, rivers reflect both the natural and social history of our planet. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Available in PDF, EPUB and Kindle. Book excerpt: In Before the Flood Jacob Blanc traces the protest movements of rural Brazilians living in the shadow of the Itaipu dam—the largest producer of hydroelectric power in the world. In the 1970s and 1980s, local communities facing displacement took a stand against the military officials overseeing the dam's construction, and in the context of an emerging national fight for democracy, they elevated their struggle for land into a referendum on the dictatorship itself. Unlike the broader campaign against military rule, however, the conflict at Itaipu was premised on issues that long predated the official start of dictatorship: access to land, the defense of rural and indigenous livelihoods, and political rights in the countryside. In their efforts against Itaipu and through conflicts among themselves, title-owning farmers, landless peasants, and the Avá-Guarani Indians articulated a rural-based vision for democracy. Through interviews and archival research—including declassified military documents and the first-ever access to the Itaipu Binational Corporation—Before the Flood challenges the primacy of urban-focused narratives and unearths the rural experiences of dictatorship and democracy in Brazil.
Book Synopsis Amazonian Floodplain Forests by : Wolfgang J. Junk
Download or read book Amazonian Floodplain Forests written by Wolfgang J. Junk and published by Springer Science & Business Media. This book was released on 2010-09-27 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: Central Amazonian floodplain forests are an unique and endangered ecosystem. The forests grow in areas that are annually flooded by large rivers during mean periods of up to 8 months and at depths of up to 10 m. Despite this severe stress, these forests consist of over 1,000 species and are by far the most species-rich floodplain forests worldwide. The trees show a broad range of morphological, anatomical, physiological, and phenological adaptations that enable them not only to survive the adverse environmental conditions, but also to produce large amounts of biomass when the nutrient levels in water and soils are sufficiently high. This is the case in the floodplains of white-water rivers, which are used for fisheries, agriculture, and cattle-ranching but which also have a high potential for the production of timber and non-timber products, when adequately managed. Latest research on ecophysiology gives insight how tree species adapt to the oscillating flood-pulse focusing on their photosynthesis, respiration, sap flow, biochemistry, phenology, wood and leave anatomy, root morphology and functioning, fruit chemistry, seed germination, seedling establishment, nitrogen fixation and genetic variability. Based on tree ages, lifetime growth rates and net primary production, new concepts are developed to improve the sustainability of traditional forest managements in the background of an integrated natural resource management. This is the first integrative book on the functioning and ecologically oriented use of floodplain forests in the tropics and sub-tropics.It provides fundamental knowledge for scientist, students, foresters and other professionals on their distribution, evolution and phytogeography. “This book is an excellent testimony to the interdisciplinary collaboration of a group of very dedicated scientists to unravel the functioning of the Amazonian Floodplain forests. They have brought together a highly valuable contribution on the distribution, ecology, primary production, ecophysiology, typology, biodiversity, and human use of these forests offering recommendations for sustainable management and future projects in science and development of these unique wetland ecosystems. It lays a solid scientific foundation for wetland ecologists, foresters, environmentalists, wetland managers, and all those interested in sustainable management in the tropics and subtropics.” Brij Gopal, Executive Vice President International Society for Limnology (SIL).

Book Synopsis Tropical Biology and Conservation Management - Volume V by : Kleber Del Claro
Download or read book Tropical Biology and Conservation Management - Volume V written by Kleber Del Claro and published by EOLSS Publications. This book was released on 2009-05-11 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Encyclopedia of Tropical Biology and Conservation Management is a component of the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Tropical environments cover the most part of still preserved natural areas of the Earth. The greatest biodiversity, as in terms of animals and plants, as microorganisms, is placed in these hot and rainy ecosystems spread up and below the Equator line. Additionally, the most part of food products, with vegetal or animal origin, that sustain nowadays human beings is direct or undirected dependent of tropical productivity. Biodiversity should be looked at and evaluated not only in terms of numbers of species, but also in terms of the diversity of interactions among distinct organisms that it maintains. In this sense, the complexity of web structure in tropical systems is a promise of future to nature preservation on Earth. In the chemicals of tropical plant and animals, could be the cure to infinite number of diseases, new food sources, and who knows what more. Despite these facts tropical areas have been exploited in an irresponsible way for more than 500 years due the lack of an ecological conscience of men. Exactly in the same way we did with temperate areas and also tropical areas in the north of Equator line. Nowadays, is estimated that due human exploitation, nation conflicts and social problems, less than 8% of tropical nature inside continental areas is still now untouchable. The extension of damage in the tropical areas of oceans is unknown. Thus so, all knowledge we could accumulate about tropical systems will help us, as in the preservations of these important and threatened ecosystems as in a future recuperation, when it was possible. Only knowing the past and developing culture, mainly that directed to peace, to a better relationship among nations and responsible use and preservation of natural resources, human beings will have a long future on Earth. These volumes, Tropical Biology and Natural Resources was divided in sessions to provide the reader the better comprehension possible of issue and also to enable future complementation and improvements in the encyclopedia. Like we work with life, we intended to transform this encyclopedia also in a “life” volume, in what new information could be added in any time. As president of the encyclopedia and main editor I opened the theme with an article titled: “Tropical Biology and Natural resources: Historical Pathways and Perspectives”, providing the reader an initial view of the origins of human knowledge about the tropical life, and what we hope to the future. In the sequence we have more than 100 chapters distributed in tem sessions: Tropical Ecology (TE); Tropical Botany (TB); Tropical Zoology (TZ); Savannah Ecosystems (SE); Desert Ecosystems (DE); Tropical Agriculture (TA); Natural History of Tropical Plants (NH); Human Impact on Tropical Ecosystems (HI); Tropical Phytopathology and Entomology (TPE); Case Studies (CS). This 11-volume set contains several chapters, each of size 5000-30000 words, with perspectives, applications and extensive illustrations. It is the only publication of its kind carrying state-of-the-art knowledge in the fields of Tropical Biology and Conservation Management and is aimed, by virtue of the several applications, at the following five major target audiences: University and College Students, Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers and NGOs.
