Download or read book The Cerrados of Brazil written by Paulo S. Oliveira and published by Columbia University Press. This book was released on 2002-10-02 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the imperiled Brazilian rainforest has been the focus of considerable international media attention and conservation efforts, the massive grasslands of Brazil—known as the cerrados—which cover roughly a quarter of its land surface and are among the most threatened regions in South America, have received little notice. This book brings together leading researchers on the area to produce the first detailed account in English of the natural history and ecology of the cerrado/savanna ecosystem. Given their extent and threatened status, the richness of their flora and fauna, and the lack of familiarity with their unique ecology at the international level, the cerrados are badly in need of this important and timely work.

Download or read book Patterns of Woody Growth for Brazilian Savanna Cerrado Trees in the Cuiaba Basin and Pantanal of Mato Grosso Brazil written by Anthony J. Zappia and published by . This book was released on 2016 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Brazilian savanna, locally known as the Cerrado, is a major ecosystem that covers a vast majority of central Brazil. Little is known about how woody growth within the Cerrado is affected by soil physical and chemical properties. In this study, the relationship between woody growth and soil physical and chemical properties was assessed in upland and seasonally flooded (hyperseasonal) cerrado located in the Cuiaba Basin and Pantanal of Mato Grosso, Brazil, respectively. We sampled from nine vegetation stands representative of the Cerrado. Diameter at breast height, wood cores, and soil nutrient concentration were measured every 5-10 m along a 100 m transect randomly installed in each stand. Correlation coefficients were used to assess the relationships between selected ecosystem and surface soil variables. Wood Carbon (C) storage was positively correlated with nitrogen (N), potassium (K), cation exchange capacity (CEC), and clay/silt soil content but was negatively correlated with sand soil content and bulk density. ANCOVA tests were used to analyze the relationships between C storage and surface soil variables based on site hydrology. There were no differences in the relationships between C storage and soil properties despite different hydrological regimes for upland and hyperseasonal sites. Ultimately, this study suggests that cerrado C storage is nutrient limited. Anthropogenic activities, such as deforestation, cattle ranching, and climate change, within the area could threaten and alter the relationships between cerrado vegetation growth and soil nutrient availability. This study aids in profiling cerrado ecosystem C storage and examines its role as a C sink in the global C cycle

Available in PDF, EPUB and Kindle. Book excerpt: More often than not, when people think of a neotropical forest, what comes to mind is a rain forest, rather than a dry forest. Just as typically, when they imagine a savanna, they visualize the African plains, rather than those dry woodlands and grasslands found in the Neotropics. These same preconceptions can be found among scientists, as these ne
Download or read book Biodiversity in Ecosystems written by Juan A. Blanco and published by BoD – Books on Demand. This book was released on 2015-04-17 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term biodiversity has become a mainstream concept that can be found in any newspaper at any given time. Concerns on biodiversity protection are usually linked to species protection and extinction risks for iconic species, such as whales, pandas and so on. However, conserving biodiversity has much deeper implications than preserving a few (although important) species. Biodiversity in ecosystems is tightly linked to ecosystem functions such as biomass production, organic matter decomposition, ecosystem resilience, and others. Many of these ecological processes are also directly implied in services that the humankind obtains from ecosystems. The first part of this book will introduce different concepts and theories important to understand the links between ecosystem function and ecosystem biodiversity. The second part of the book provides a wide range of different studies showcasing the evidence and practical implications of such relationships.

This book was released on 2013-06-29 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomass burning profoundly affects atmospheric chemistry, the carbon cycle, and climate and may have done so for millions of years. Bringing together renowned experts from paleoecology, fire ecology, atmospheric chemistry, and organic chemistry, the volume elucidates the role of fire during global changes of the past and future. Topics covered include: the characterization of combustion products that occur in sediments, including char, soot/fly ash, and polycyclic aromatic hydrocarbons; the calibration of these constituents against atmospheric measurements from wildland and prescribed fire emissions; spatial and temporal patterns in combustion emissions at scales of individual burns to the globe.
Download or read book Neotropical Gradients and Their Analysis written by Randall W. Myster and published by Springer Nature. This book was released on 2023-03-31 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of the Neotropics to the world's climate, biogeochemical cycling and biodiversity cannot be questioned. This book suggests that gradients are key to understanding both these issues and Neotropical ecosystem structure, function and dynamics in general. Those gradients are either spatial, temporal or spatio-temporal, where many temporal and spatio-temporal gradients are initiated by disturbances (e.g., tree-fall, landslide, cultivation). And in particular for the Neotropics, three large spatial gradients - latitude, longitude, altitude (elevation) - are of critical importance. The editor has over 30 years of experience investigating Neotropical gradients in Costa Rica, Puerto Rico, Peru and Ecuador, and has published 5 previous books on different aspects of the Neotropics. Once again he has assembled top-shelf Neotropical scientists and researchers, here to focus on gradients: their nature, interactions and how they structure ecosystems.

Download or read book Evolution of Tree Architecture in the Brazilian Cerrado written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The tropical savanna-forest boundary is commonly characterized by an abrupt transition in vegetation structure and in tree species composition. It has been hypothesized that differences in architecture between savanna and forest trees have an important role in determining the contrasting structural differences between savanna and forest ecosystems. Because of the importance the vegetation structure in determining the ecosystem properties of these systems, I performed a comparative study of tree architecture to examine differences in plant structure of savanna and forest species. To eliminate the potential bias from phylogenetic relatedness, I used congeneric species pairs containing trees of both habitat types that occur sympatrically in savannas of the Brazilian cerrado habitat at IBGE Ecological Reserve (RECOR). I found that relative to savanna species, forest species have larger crown volumes with more apical meristems and greater height for a given stem diameter. Other traits that influence patterns of light interception also differed, with savanna species exhibiting more convoluted leaf blades and shorter petioles. There was evidence that allometry and other traits are convergent in savanna and forest tree species across lineages, providing strong support for adaptive functions of these traits. Furthermore, the larger canopies of forest species imply that they play a role in reduced light in the understory and the exclusion of grasses, which potentially facilitates further expansion of forest tree species in the absence of fire.
Download or read book Tropical Fire Ecology written by Mark Cochrane and published by Springer Science & Business Media. This book was released on 2010-04-11 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tropics are home to most of the world’s biodiversity and are currently the frontier for human settlement. Tropical ecosystems are being converted to agricultural and other land uses at unprecedented rates. Land conversion and maintenance almost always rely on fire and, because of this, fire is now more prevalent in the tropics than anywhere else on Earth. Despite pervasive fire, human settlement and threatened biodiversity, there is little comprehensive information available on fire and its effects in tropical ecosystems. Tropical deforestation, especially in rainforests, has been widely documented for many years. Forests are cut down and allowed to dry before being burned to remove biomass and release nutrients to grow crops. However, fires do not always stop at the borders of cleared forests. Tremendously damaging fires are increasingly spreading into forests that were never evolutionarily prepared for wild fires. The largest fires on the planet in recent decades have occurred in tropical forests and burned millions of hectares in several countries. The numerous ecosystems of the tropics have differing levels of fire resistance, resilience or dependence. At present, there is little appreciation of the seriousness of the wild fire situation in tropical rainforests but there is even less understanding of the role that fire plays in the ecology of many fire adapted tropical ecosystems, such as savannas, grasslands and other forest types.
Download or read book Tropical Stream Ecology written by David Dudgeon and published by Elsevier. This book was released on 2011-05-04 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical Stream Ecology describes the main features of tropical streams and their ecology. It covers the major physico-chemical features, important processes such as primary production and organic-matter transformation, as well as the main groups of consumers: invertebrates, fishes and other vertebrates. Information on concepts and paradigms developed in north-temperate latitudes and how they do not match the reality of ecosystems further south is expertly addressed. The pressing matter of conservation of tropical streams and their biodiversity is included in almost every chapter, with a final chapter providing a synthesis on conservation issues. For the first time, Tropical Stream Ecology places an important emphasis on viewing research carried out in contributions from international literature. First synthetic account of the ecology of all types of tropical streams Covers all of the major tropical regions Detailed consideration of possible fundamental differences between tropical and temperate stream ecosystems Threats faced by tropical stream ecosystems and possible conservation actions Descriptions and synstheses life-histories and breeding patterns of major aquatic consumers (fishes, invertebrates)
