Many conservationists argue that invasive species form one of the most important threats to ecosystems the world over, often spreading quickly through their new environments and jeopardising the conservation of native species. As such, it is important that reliable predictions can be made regarding the effects of new species on particular habitats. This book provides a critical appraisal of ecosystem theory using case studies of biological invasions in Australasia. Each chapter is built around a set of eleven central hypotheses from community ecology, which were mainly developed in North American or European contexts. The authors examine the hypotheses in the light of evidence from their particular species, testing their power in explaining the success or failure of invasion and accepting or rejecting each hypothesis as appropriate. The conclusions have far-reaching consequences for the utility of community ecology, suggesting a rejection of its predictive powers and a positive reappraisal of natural history.

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.

Northern Australia stands out as one of the largest natural areas remaining on Earth - alongside such global treasures as the Amazon rainforests, the boreal conifer forests of Alaska and Canada, and the polar wilderness of Antarctica. Nature remains in abundance in 'the North'. Its intact tropical savannas, rainforests, and free flowing rivers provide a basis for much of the economic activity and the quality of life for residents of the area. THE NATURE OF NORTHERN AUSTRALIA details the latest science on the Northern environment. With increasing debate over the future of Australias often forgotten North, this is a timely examination of its environmental significance, the ecological processes that make it function, and the economies that are compatible with maintaining healthy communities and people and healthy country into the future.

Tropical Forage Plants: Development and Use covers the research and resulting pasture development in the tropics and subtropics, which has undergone dramatic changes in the past few decades. Providing a broad, global perspective, it serves as a comprehensive resource covering a wide range of subjects pertaining to forage and animal production in th

A beautifully illustrated reference work on the biology, ecology, conservation status and management of all thirteen species of wild cattle and buffalo. This book will be a valuable resource for students, researchers, and professionals in animal behaviour, behavioural ecology, evolutionary biology and conservation biology.

Ants are one of the most important faunal groups in Australia and are widely used as bioindicators in land monitoring and assessment programs. The Ants of Northern Australia will help in the identification of the 1500 or more ant species occurring in monsoonal Australia, an area which encompasses most of the northern third of the continent. Until now, no book has described the northern Australian ant fauna below genus level. Such a treatment is required to support and promote the numerous ecological studies involving ants, especially in the context of their use as bioindicators. The Ants of Northern Australia features original analyses of genera at the species-group level, and so has relevance throughout Australia. It treats all major species that have been described, as well as numerous others that remain undescribed.
