Collection of papers from a satellite symposium of the Sixth International Theriological Congress held in Sydney in 1993. Topics addressed include comparative structure and function of marsupial spermatazoa, and male-induced oestrus and ovulation in female brush-tailed bettongs. Also provides an overview of development of early cell lineages in marsupial embryos. Includes references.

Marsupials differ from most other mammals in their method of reproduction, in that they have chosen, in an evolutionary sense, to develop lactation rather than placentation for the nurture of their young. The neonate is therefore born with a mixture of advanced and embryonic characters, and yet is readily accessible within the pouch, providing a unique system for the study of the ontogeny of various physiological and endocrinological parameters. Marsupials are therefore ideal animals for research into mammalian reproductive physiology. The results of this exciting new research are summarized in this book by two of the foremost workers in the field. Individual chapters analyse the genetic and hormonal control of sexual differentiation, male and female reproductive structures and their functions, the role of the corpus luteum in the oestrous cycle and pregnancy, the hormonal control of embryonic diapause and the role of the marsupial placenta in the development of the embryo. This book is more than just a straightforward review of marsupial reproduction for its detailed analyses and broad comparative coverage will attract mammalogists and reproductive physiologists with a wide range of research interests.

Marsupials are excellent objects for studies on developmental processes in all mammals including humans. Marsupials are very immature at birth and undergo most of their development in a pouch where they can be manipulated in a variety of ways without affecting the mother. Most of these studies are on systems which largely mature before birth in eutherian mammals and are consequently difficult to investigate. Attention is also drawn to certain features peculiar to adult marsupials: e.g., they continue to grow throughout adult life, valuable for studies on growth mechanisms, and furthermore the composition of marsupial milk changes radically through lactation, most important in studies of hormonal regulation of milk composition and secretion.

Predators with Pouches provides a unique synthesis of current knowledge of the world’s carnivorous marsupials—from Patagonia to New Guinea and North America to Tasmania. Written by 63 experts in each field, the book covers a comprehensive range of disciplines including evolution and systematics, reproductive biology, physiology, ecology, behaviour and conservation. Predators with Pouches reveals the relationships between the American didelphids and the Australian dasyurids, and explores the role of the marsupial fauna in the mammal community. It introduces the geologically oldest marsupials, from the Americas, and examines the fall from former diversity of the larger marsupial carnivores and their convergent evolution with placental forms. The book covers all aspects of carnivorous marsupials, including interesting features of life history, their unique reproduction, the physiological basis for early senescence in semelparous dasyurids, sex ratio variation and juvenile dispersal. It looks at gradients in nutrition—from omnivory to insectivory to carnivory—as well as distributional ecology, social structure and conservation dilemmas.

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.

Over the past half a century research has revealed that marsupials – far from being ‘second class’ mammals – have adaptations for particular ways of life quite equal to their placental counterparts. Despite long separate evolution, there are extraordinary similarities in which marsupials have solved the challenges of living in such environments as deserts, alpine snowfields or tropical rainforests. Some can live on grass, some on pollen and others on leaves; some can glide, some can swim and others hop with extraordinary efficiency. In Life of Marsupials, one of the world’s leading experts explores the biology and evolution of this unusual group – with their extraordinary diversity of forms around the world – in Australia, New Guinea and South America. Joint winner of the 2005 Whitley Medal. Included in Choice Magazine's 2006 Outstanding Academic Titles list.
