Why do Australian rainforests occur as islands within the vast tracts of Eucalyptus? Why is fire a critical ecological factor in every Australian landscape? What were the consequences of the use of fire by the Ice Age colonists? In this original and challenging book, David Bowman critically examines all hypotheses that have been advanced to answer these questions. He demonstrates that fire is the most critical factor in controlling the distribution of rainforest throughout Australia. Furthermore, while Aboriginal people used fire to skillfully manage and preserve habitats, he concludes that they did not significantly influence the evolution of Australia's unique flora and fauna. This volume, the first comprehensive overview of the diverse literature on this topic, solves the puzzle of the archipelago of rainforest habitats in Australia. It is essential reading for all ecologists, foresters, conservation biologists, and others interested in the biogeography and ecology of Australian rainforests.
Created specifically to help designers master AutoCAD, "Digital Drawing for Designers 2014" is neither overly simplistic nor excessively technical, and teaches by relating to what architects and interior designers understand best: the visual world. Beginning with the building blocks of drawing (lines, circles, and arcs), the book progresses through architectural graphic standards, enabling students to create drawings that effectively communicate their design ideas. Advanced features such as annotative dimensions, annotative blocks, express tools, and linking drawings (XREFs) are also covered. Instructions are illustrated using language and concepts from manual drafting, facilitating a smooth transition to the digital environment for all designers. New learners will appreciate the step-by-step lessons and visual illustrations, while experienced design professionals can easily access material to refresh their knowledge. Clear, concise, and above all visual, this AutoCAD guide speaks directly to the needs of architects and interior designers.
