This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire is an important factor affecting plant diversity and vegetation dynamics in subtropical grasslands in southern Brazil. Although fire is a useful management tool in many ecosystems, in Brazil its use is forbidden and very polemic. Therefore, the aim of this thesis is to evaluate the effects of fire on plant strategies and vegetation dynamics. The study was carried out in southern Brazil (Rio Grande do Sul State). Experimental fires and mowing were performed and vegetation regeneration was analyzed according to different functional groups and plant strategies. In addition, population biology of chosen species was studied in order to investigate effects of fire on plant populations. Finally, studies about the bud bank were conducted to evaluate vegetation potential to regenerate after fire events. The results of this thesis are of crucial importance for the conservation of subtropical grasslands in southern Brazil.

Download or read book Distributions for Modeling Location Scale and Shape written by Robert A. Rigby and published by CRC Press. This book was released on 2019-10-08 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a book about statistical distributions, their properties, and their application to modelling the dependence of the location, scale, and shape of the distribution of a response variable on explanatory variables. It will be especially useful to applied statisticians and data scientists in a wide range of application areas, and also to those interested in the theoretical properties of distributions. This book follows the earlier book ‘Flexible Regression and Smoothing: Using GAMLSS in R’, [Stasinopoulos et al., 2017], which focused on the GAMLSS model and software. GAMLSS (the Generalized Additive Model for Location, Scale, and Shape, [Rigby and Stasinopoulos, 2005]), is a regression framework in which the response variable can have any parametric distribution and all the distribution parameters can be modelled as linear or smooth functions of explanatory variables. The current book focuses on distributions and their application. Key features: Describes over 100 distributions, (implemented in the GAMLSS packages in R), including continuous, discrete and mixed distributions. Comprehensive summary tables of the properties of the distributions. Discusses properties of distributions, including skewness, kurtosis, robustness and an important classification of tail heaviness. Includes mixed distributions which are continuous distributions with additional specific values with point probabilities. Includes many real data examples, with R code integrated in the text for ease of understanding and replication. Supplemented by the gamlss website. This book will be useful for applied statisticians and data scientists in selecting a distribution for a univariate response variable and modelling its dependence on explanatory variables, and to those interested in the properties of distributions.
Download or read book The Cerrados of Brazil written by Paulo S. and published by Columbia University Press. This book was released on 2013-02-05 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 media attention. 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 Prairie Conservation written by Fred B. Samson and published by Island Press. This book was released on 1996-08 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: The area of native prairie known as the Great Plains once extended from Canada to the Mexican border and from the foothills of the Rocky Mountains to western Indiana and Wisconsin. Today the declines in prairie landscape types, estimated to be as high as 99%, exceed those of any other major ecosystem in North America. The overwhelming loss of landscape and accompanying loss of species constitute a real threat to both ecological and human economic health.Prairie Conservation is a comprehensive examination of the history, ecology, and current status of North American grasslands. It presents for the first time in a single volume information on the historical, economic, and cultural significance of prairies, their natural history and ecology, threats, and conservation and restoration programs currently underway. Chapters cover: environmental history of the Great Plains the economic value of prairie prairie types -- tallgrass, mixed grass, shortgrass, wetlands -- and the ecological processes that sustain each type prairie fauna -- invertebrates, fish and other aquatic creatures, amphibians and reptiles, birds, and mammals conservation programs such as the Great Plains Partnership, Canada's Prairie Conservation Action Plan, the U.S. Prairie Pothole Joint Venture, and others The book brings together knowledge and insights from a wide range of experts to describe and explain the importance of prairies and to position them in the forefront of North American conservation efforts. Praire Conservation is an essential reference for anyone interested in prairie ecology and conservation and will play a critical role in broadening our awareness and understanding of prairie ecosystems.
Download or read book Savanna Woody Plants and Large Herbivores written by Peter Frank Scogings and published by John Wiley & Sons. This book was released on 2019-09-30 with total page 794 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insights on current research and recent developments in understanding global savanna systems Increasingly recognized as synonymous with tropical grassy biomes, savannas are found in tropical and sub-tropical climates as well as warm, temperate regions of North America. Savanna Woody Plants and Large Herbivores examines the interactions between woody plants and browsing mammals in global savannas—focusing primarily on the C4 grassy ecosystems with woody components that constitute the majority of global savannas—and discusses contemporary savanna management models and applications. This much-needed addition to current research examines topics including the varying behavior of browsing mammals, the response to browsing by woody species, and the factors that inhibit forage intake. Contributions from an international team of active researchers and experts compare and contrast different savanna ecosystems, offering a global perspective on savanna functioning, the roles of soil and climate in resource availability and organism interaction, and the possible impacts of climate change across global savannas. Fills a gap in literature on savanna management issues, including biodiversity conservation and animal production Applies concepts developed in other biomes to future savanna research Complements contemporary books on savanna or large herbivore ecology Focuses on the woody component of savanna ecosystems and large herbivore interactions in savannas Compares tree-mammal systems of savannas and other eco-systems of temperate and boreal regions Provides numerous case studies of plant-mammal interactions from various savanna ecosystems Savanna Woody Plants and Large Herbivores is a valuable addition to those in fields such as ecology, wildlife and conservation biology, natural resource management, and environmental science.
Download or read book Fire in the Tropical Biota written by Johann G. Goldammer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1977, the Volkswagen Foundation sponsored the first of a series of International Symposia on Fire Ecology at Freiburg University, Federal Republic of Germany. The scope of the congresses was to create a platform for researchers at a time when the science of fire ecology was not yet recognized and established outside of North America and Australia. Whereas comprehensive information on the fire ecology of the northern boreal, the temperate, and the mediter ranean biotas is meanwhile available, it was recognized that conside rable gaps in information exist on the role of fire in tropical und sub tropical ecosystems. Thus it seemed timely to meet the growing scientific interest and public demand for reliable and updated infor mation and to synthesize the available knowledge of tropical fire ecology and the impact of tropical biomass burning on global eco system processes. The Third Symposium on Fire Ecology, again sponsored by the Volkswagen Foundation and held at Freiburg University in May 1989, was convened to prepare this first pantropical and multidisci plinary monograph on fire ecology!. The book, in which 46 scientists cooperated, analyzes those fire-related ecosystem processes which have not yet been described in a synoptic way. Following the editor's concept, duplication at previous efforts in describing tropical vegeta tion patterns and dynamics was avoided. Extensive bibliographical sources are given in the reference lists of the chapters.
Download or read book Global Application of Prescribed Fire written by John R. Weir and published by CSIRO PUBLISHING. This book was released on 2022-02 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global Application of Prescribed Fire provides a first-hand perspective of the various methods and ways people around the world view and use prescribed fire. It covers the logistics, constraints and social dynamics surrounding the intentional use and application of fire by humans, and demonstrates how, why, when and where prescribed fire is used in different regions. Written by international experts, the book has four key objectives: explore new techniques, ideas and thoughts on how to apply prescribed fire from a global perspective; provide regional case studies covering issues that may constrain or enhance prescribed fire projects; stimulate cross-cultural conversations about how fires function in ecosystems; and relate prescribed fire to wildfire regimes with implications for protecting life and property, as well as sustaining local fire cultures and unique fire-dependent flora and fauna. Global Application of Prescribed Fire enhances our understanding and knowledge about the application of prescribed fire. This comprehensive book will provide fire practitioners, researchers, agencies and policymakers with key ecological and managerial insight of how prescribed fires are conducted around the globe.

Download or read book Grassland Biodiversity written by Johan Runas and published by . This book was released on 2010 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Genetic diversity and species diversity are both crucial for ecosystem stability. Analysis of plant diversity aims to understand the organization and the variability of biological populations within ecosystems. This book provides a review on chemotaxonomical criteria helping to understand complex structures of plant diversity. It focuses particularly on the chemotaxonomic usefulness of phenolic compounds in analysis of chemical polymorphisms at different taxonomic levels. The relationship between grazing pressure and grassland vegetation is also examined, using drastically improved information technology such as remote sensing, Geographic Information System (GIS) and Ground Positioning Systems (GPS). Furthermore, an overview of the unique ecosystem of the South Brazilian Campos grasslands are given. The role of disturbance in maintaining Campos biodiversity and dynamics, and the importance of its conservation, is looked at as well. Other chapters in this book discuss the relationship between management and vegetation, and also suggest ways to conserve the species diversity of both plants and butterflies in semi-natural grassland."--Publisher's description.

Available in PDF, EPUB and Kindle. Book excerpt: Based on papers presented at a 1987 symposium, "Fire in North American Grasslands," cosponsored by the Ecological Society of America and the Botanical Society of America, this book represents an important contribution to key unanswered questions concerning the role of fire in grassland ecosystems: How often did fires occur in the past? Were they primarily natural or caused by humans? At what time of year did grasslands normally burn? How should fire be used as a management tool? What constitutes a proper prescribed burning regime both with and without grazing?
