Intended as a laboratory guide, this atlas will allow users to accurately identify species and size of fish using otoliths. The main features presented for each species, include brief distribution and ecology notes, regression for otolith and fish lengths, and standardised description of the otolith structure.
The accurate identification of fish ‘ear-bones’, known as otoliths, is essential to determine the fish prey of marine and terrestrial predators. Fish otoliths are species-specific when combining size, shape and surface features, and can remain undigested for long periods. As a result, they can indicate which fish make up the diet of various predators, including cephalopod, seabird, marine mammal and fish species. Such studies are crucial for understanding marine ecosystems, and trophodynamics in particular. Increasingly, these methods are being used to understand the diet of some terrestrial predators, also extending to that of humans in archaelogical studies. Otoliths of Common Australian Temperate Fish offers users a verified reference collection to assist in the accurate identification of species and size of fish using otoliths. It covers 141 fish species from a broad geographic range of the Australian temperate region and includes commercial and non-commercial fish species. A standardised written description of the otolith structure, size and surface features is provided for each species. Included are brief distribution and ecology notes, and regression for both otolith and fish lengths, together with high-quality SEM photographs of the otolith described. This guide will be an essential reference for marine scientists and marine mammal researchers; ornithologists, fisheries researchers and fish biologists studying age and growth or comparative anatomy; and archaeologists.

Techniques and theory for processing otoliths from tropical marine fish have developed only recently due to an historic misconception that these organisms could not be aged. Otoliths are the most commonly used structures from which daily, seasonal or annual records of a fish’s environmental history are inferred, and are also used as indicators of migration patterns, home range, spatial distribution, stock structure and life history events. A large proportion of projects undertaken on tropical marine organisms involve removal and processing of calcified structures such as otoliths, statoliths or vertebrae to retrieve biological, biochemical or genetic information. Current techniques and principles have evolved rapidly and are under constant modification and these differ among laboratories, and more particularly among species and within life history stages. Tropical fish otoliths: Information for assessment, management and ecology is a comprehensive description of the current status of knowledge about otoliths in the tropics. This book has contributions from leading experts in the field, encompassing a tropical perspective on daily and annual ageing in fish and invertebrates, microchemistry, interpreting otolith microstructure and using it to back-calculate life history events, and includes a treatise on the significance of validating periodicity in otoliths.
Most living carnivorous marsupials lead a secretive and solitary existence. From tiny insect eaters to the formidable Tasmanian Devil, Secret Lives of Carnivorous Marsupials offers rare insight into the history and habits of these creatures – from their discovery by intrepid explorers and scientists to their unique life cycles and incredible ways of hunting prey. Secret Lives of Carnivorous Marsupials provides a guide to the world’s 136 living species of carnivorous marsupials and is packed with never-before-seen photos. Biogeography, relationships and conservation are also covered in detail. Readers are taken on a journey through remote Australia, the Americas and dark, mysterious New Guinea – some of the last truly wild places on Earth. The book describes frenzied mating sessions, minuscule mammals that catch prey far larger than themselves, and extinct predators including marsupial lions, wolves and even sabre-toothed kangaroos.
