Geomorphometry is the science of quantitative terrain characterization and analysis, and has traditionally focused on the investigation of terrestrial and planetary landscapes. However, applications of marine geomorphometry have now moved beyond the simple adoption of techniques developed for terrestrial studies, driven by the rise in the acquisition of high-resolution seafloor data and by the availability of user-friendly spatial analytical tools. Considering that the seafloor represents 71% of the surface of our planet, this is an important step towards understanding the Earth in its entirety. This volume is the first one dedicated to marine applications of geomorphometry. It showcases studies addressing the five steps of geomorphometry: sampling a surface (e.g., the seafloor), generating a Digital Terrain Model (DTM) from samples, preprocessing the DTM for subsequent analyses (e.g., correcting for errors and artifacts), deriving terrain attributes and/or extracting terrain features from the DTM, and using and explaining those terrain attributes and features in a given context. Throughout these studies, authors address a range of challenges and issues associated with applying geomorphometric techniques to the complex marine environment, including issues related to spatial scale, data quality, and linking seafloor topography with physical, geological, biological, and ecological processes. As marine geomorphometry becomes increasingly recognized as a sub-discipline of geomorphometry, this volume brings together a collection of research articles that reflect the types of studies that are helping to chart the course for the future of marine geomorphometry.

This book tells the fascinating success story of saving the flightless Woodhen of Lord Howe Island. This unique large rail, an iconic and highly endangered Australian bird, was at the very brink of extinction with just 15 individuals found in 1980, when bold and risky actions were taken to save it. The book begins with the discovery and ecology of Lord Howe Island. It then details the history of the Woodhen, its place among the rails and their evolution of flightlessness, the planning, implementation and trials, tribulations and successes of the captive breeding programme and the way in which the wild population recovered. The ecology, behaviour and breeding biology of this unique flightless island rail are also discussed. The text is accompanied by numerous photographs and drawings. This is a story of survival, yet the bird remains highly endangered as it is under constant potential threat, which could tip it over the brink and to extinction. The Woodhen provides gripping insights into the potential for both losing and saving vertebrate species. Winner of a 2014 Whitley Awards Certificate of Commendation for Historical Zoology.
The islands of the tropical Pacific Ocean encompass a vast range of climate, geography, and geology. The flora of these islands is similarly diverse, and the study of their vegetation and landscapes is a challenge because of the great distances separating them. Dieter Mueller-Dombois and the late F. Raymond Fosberg are recognized as the leading authorities on the plant diversity and ecology of Pacific islands. This book is a synthesis of the vegetation and landscapes of the islands of the Pacific Ocean. It is organized by island group and includes information on geography, geology, and climate, as well as soil and vegetation types, land use, floristic patterns, phytogeographic relationships, and human influences on vegetation. The book features over 400 color photographs, plus dozens of maps and climate diagrams.
Phasmid is the amazing true story of the Lord Howe Island Phasmid, or Stick Insect. Believed to be extinct for nearly 80 years, the phasmids were rediscovered on Balls Pyramid, a volcanic outcrop 23 kilometres off the coast of Lord Howe Island, Australia. News of their unbelievable survival made headlines around the world and prompted an extraordinary conservation effort to save this remarkable invertebrate. This wonderful tale captures the life of one of the world's most critically endangered invertebrates, from beginning life as an egg to surviving harsh environments and the hopeful return to their homeland, Lord Howe Island. With a captivating narrative by Rohan Cleave, invertebrate zookeeper at Melbourne Zoo, and stunning watercolour illustrations by renowned artist Coral Tulloch, Phasmid is a positive story about one species' incredible survival in a time of worldwide species decline. Phasmid is ideal for parents and young readers (aged 4-7).
