Fire in the Tropical Biota


Book Description

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.

Tropical Fire Ecology


Book Description

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.




Fire in Tropical Savannas


Book Description

Fire is a major agent of disturbance in many biomes of the world but is a particularly important feature of tropical savannas. Up to 50% of the ext- sive tropical savanna landscapes of northern Australia are burnt each year. This includes prestigious conservation reserves such as World Heritage— listed Kakadu National Park, in the Top End of the Northern Territory. As in other savanna regions of the world, the responses of biota to different ?re regimes are poorly understood, such that ?re management represents one of the greatest challenges to conservation managers and researchers alike. This is the context within which a landscape-scale ?re experiment was established at Kapalga Research Station in Kakadu,which aimed to provide a sound scienti?c basis for conservation management in the region. The experiment was established by The Australian Commonwealth Scienti?c and Industrial Research Organization (CSIRO),but involved collaborators from a range of universities and government agencies, including the m- agers of Kakadu,the Australian Nature Conservation Agency (ANCA:now Parks Australia North). This book summarizes the ?ndings from the Kapalga ?re experiment and explores the implications for conservation management. We believe that Kapalga has provided important insights into the ?re ecology of tropical savannas and has broad relevance for the conservation management of ?- prone landscapes in general. This book should be of interest to researchers, graduate students, and land management agencies. vii viii Preface We are extremely grateful to all our collaborators,both inside and outside CSIRO, for their involvement in the Kapalga experiment.

The Ecology of Fire


Book Description

Wildfires kill many animals, but are populations of animals affected? How do animals survive the passage of fire? Why do some tree species survive and others die in a fire? Do frequent fires cause changes in plant community composition? Answering questions such as these requires an understanding of the ecological effects of fire. Aimed at senior undergraduate students, researchers, foresters and other land managers, Dr Whelan's book examines the changes wrought by fires with reference to general ecological theory. The impacts of fires on individual organisms, populations and communities are examined separately, and emphasis is placed on the importance of fire regime. Each chapter includes a listing of 'outstanding questions' that identify gaps in current knowledge. The book finishes by summarising the major aspects of ecology that are of particular relevance to management of fires - both protection against wildfires and deliberate use of fire.

Sediment Records of Biomass Burning and Global Change


Book Description

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.
