Tropical Ecosystems in Australia


Book Description

Over the last century, the world has lived through changes more rapid than those experienced at any other time in human history, leading to pressing environmental problems and demands on the world’s finite resources. Nowhere is this more evident than across the world’s warm belt; a region likely to have the greatest problems and which is home to some of the world’s most disadvantaged people. This book reviews aspects of the biology of tropical ecosystems of northern Australia, as they have been affected by climatic, social and land-use changes. Tropical Australia can be regarded as a microcosm of the world’s tropics and as such, shares with other tropical regions many of the conflicts between various forms of development and environmental considerations. The book draws on a wide range of case studies of tropical Australian ecosystems ranging from coastal coral reefs and mangroves, known to be among the most vulnerable to the effects of the imposed changes, to cropping and pasture lands which, under careful management, have the potential remain as productive and sustainable agricultural or forestry ecosystems. Expert author Dilwyn Griffiths -emphasizes the importance of maintaining an active program for the establishment and management of national parks and environmental reserves -describes the effects of mining and other forms of industrial and urban development with particular reference to mine-site rehabilitation - explores problems relating to the restoration of marginally uneconomic farming land as alternative forms of land-use such as carbon farming through photosynthetically-driven carbon sequestration. This accessible reference work should find a place in educational libraries at all levels and become an essential resource for environmentalists and anyone with interests in various forms of land-use and development.

The Flowering of Australia's Rainforests


Book Description

The Flowering of Australia's Rainforests provides an overview of pollination in Australian rainforests, especially subtropical rainforests. It also examines the plant-pollinator relationships found in rainforests worldwide. The Flowering of Australia's Rainforests progresses through introductory and popular sections that cover pollination in lore and legend; plant and flower evolution and development; and the role and function of colour, fragrance and form. Later chapters deal with breeding systems; mimicry; spatial, temporal and structural influences on plant-pollinator interactions; and a discussion and overview of floral syndromes. The book concludes with a section on conservation and fragmentation, and individual plant pollination case studies. Illustrated with colour photographs of major species, this reference work will be treasured by field naturalists, ecologists, conservation biologists, botanists, ecosystem managers, environmentalists, community groups and individuals involved in habitat restoration, students, and those with a broad interest in natural history.




Biodiversity and Environmental Change


Book Description

This data-rich book demonstrates the value of existing national long-term ecological research in Australia for monitoring environmental change and biodiversity. Long-term ecological data are critical for informing trends in biodiversity and environmental change. The Terrestrial Ecosystem Research Network (TERN) is a major initiative of the Australian Government and one of its key areas of investment is to provide funding for a network of long-term ecological research plots around Australia (LTERN). LTERN researchers and other authors in this book have maintained monitoring sites, often for one or more decades, in an array of different ecosystems across the Australian continent – ranging from tropical rainforests, wet eucalypt forests and alpine regions through to rangelands and deserts. This book highlights some of the temporal changes in the environment that have occurred in the various systems in which dedicated field-based ecologists have worked. Many important trends and changes are documented and they often provide new insights that were previously poorly understood or unknown. These data are precisely the kinds of data so desperately needed to better quantify the temporal trajectories in the environment in Australia. By presenting trend patterns (and often also the associated data) the authors aim to catalyse governments and other organisations to better recognise the importance of long-term data collection and monitoring as a fundamental part of ecologically-effective and cost-effective management of the environment and biodiversity.




Global Climate Change and Tropical Ecosystems


Book Description

Tropical ecosystems - the regions between the tropics of Cancer and Capricorn - play an important role in global processes, economic issues, and political concerns. In their natural state, tropical ecosystems support a large quantity of above- and below-ground biomass, and constitute a major part of the terrestrial carbon pool. Conversion of the natural ecosystem to agriculture and forestry ecosystems disturbs this ecological balance. Global Climate Change and Tropical Ecosystems presents data on carbon pool fluxes from case studies in 12 countries in tropical regions. The chapters cover: Characteristics of tropical ecosystems Soil and biotic carbon pools Impacts of land use and soil management Slash-and-burn practices Crop residue and fertility management This volume adds to the understanding of pedospheric processes in tropical ecosystems and how to better use soils as a sink for carbon dioxide and other greenhouse gases. With Global Climate Change and Tropical Ecosystems you will understand the link between soil productivity, environmental quality and the global carbon cycle, not only in these ecologically sensitive regions but worldwide.




Tropical Rain Forest Ecosystems


Book Description

After publication of the first volume of the Tropical Rain Forest, the International Journal of Mycology and Lichenology commented ``This is a welcome addition to the literature on the ecology of tropical rain forests. The book provides a wealth of data and stimulating discussions and is of great interest to ecologists interested in tropical areas.'' Whereas the first volume dealt with system-ecological aspects such as community organization and processes, the present volume concentrates on biogeographical aspects such as species composition, diversity, and geographical variation.Recent ecological research in the tropical rain forest has greatly extended our understanding of biogeographical patterns of variation in the various groups of organisms, and has revealed many of the ecological and evolutionary forces that led to the present patterns of variation. Many important systems of co-evolution between the tropical rain forest ecosystems have also come to light, and the loss of species and related damage is better understood in quantitative terms.This volume presents a comprehensive review of these and other features of the rain forest ecosystem structure, and the ecological processes operating that system. General chapters on abiotic and biotic factors are followed by specific chapters on all major groups of organisms. Prospects for the future are discussed and research needs clearly stated. Also the human exploitation of the system, its effects and its limits are discussed. The book is extensively illustrated by photographs, graphs, and tables, and comprehensive bibliographies follow each chapter. Author, systematic and subject indices complete the book.It is a must for all ecologists, agriculturists, foresters, agronomists, hydrologists, soil scientists, entomologists, human ecologists, nature conservationists, and planners dealing with tropical areas. Biologists and environmentalists will also find the volume of great interest.




Tropical Rain Forests


Book Description

The first edition of Tropical Rain Forests: an Ecological and Biogeographical Comparison exploded the myth of ‘the rain forest’ as a single, uniform entity. In reality, the major tropical rain forest regions, in tropical America, Africa, Southeast Asia, Madagascar, and New Guinea, have as many differences as similarities, as a result of their isolation from each other during the evolution of their floras and faunas. This new edition reinforces this message with new examples from recent and on-going research. After an introduction to the environments and geological histories of the major rain forest regions, subsequent chapters focus on plants, primates, carnivores and plant-eaters, birds, fruit bats and gliding animals, and insects, with an emphasis on the ecological and biogeographical differences between regions. This is followed by a new chapter on the unique tropical rain forests of oceanic islands. The final chapter, which has been completely rewritten, deals with the impacts of people on tropical rain forests and discusses possible conservation strategies that take into account the differences highlighted in the previous chapters. This exciting and very readable book, illustrated throughout with color photographs, will be invaluable reading for undergraduate students in a wide range of courses as well as an authoritative reference for graduate and professional ecologists, conservationists, and interested amateurs.




Vegetation of Australian Riverine Landscapes


Book Description

Vegetation communities in Australia's riverine landscapes are ecologically, economically and culturally significant. They are also among the most threatened ecosystems on the continent and have been dramatically altered as a result of human activities and climate change. Vegetation of Australian Riverine Landscapes brings together, for the first time, the results of the substantial amount of research that has been conducted over the last few decades into the biology, ecology and management of these important plant communities in Australia. The book is divided into four sections. The first section provides context with respect to the spatial and temporal dimensions of riverine landscapes in Australia. The second section examines key groups of riverine plants, while the third section provides an overview of riverine vegetation in five major regions of Australia, including patterns, significant threats and management. The final section explores critical issues associated with the conservation and management of riverine plants and vegetation, including water management, salinity, fire and restoration. Vegetation of Australian Riverine Landscapes highlights the incredible diversity and dynamic nature of riverine vegetation across Australia, and will be an excellent reference for researchers, academics and environmental consultants.

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.
