Life Of Marsupials

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. -back cover.

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.

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.

The results of this compilation of new research on the reproductive physiology of marsupials reveal much about their patterns of reproduction and evolution in comparison to monotremes and eutherians.

Marsupials and monotremes are the dominant mammalian fauna in Australia, Papua New Guinea (PNG) and parts of South America. Monotremes are unique; they possess a range of reptilian and mammalian characteristics. Marsupials are highly diverse and occupy a wide range of ecologically diverse niches and habitats. They have distinct physiologies and their ability to control foetal development and nurture extremely immature young is providing beneficial insights into developmental physiology and human medicine. Insights into marsupial herbivory are benefitting agriculture and climate science. Studies on these mammals that have or will benefit mankind in medicine, agriculture and environmental science have been highlighted. This book covers current knowledge of all aspects of the basic biology and ecology of marsupials and monotremes including evolution and biogeography, genomics, musculoskeletal anatomy, thermal regulation, reproduction, nutrition and feeding strategies, behaviour and social interactions, health and disease, current conservation status, exploitation and utilisation and finally addresses this question: "Are monotremes and marsupials inferior?" The principal audience for this book will be undergraduate students at the tertiary level. Within these chapters, standalone text boxes have been incorporated with examples of the most up-to-date research undertaken to make the book a resource to research students and scientists. Many text boxes highlight the enigmatic nature of marsupials and monotremes and where knowledge of their biology could be of value to the wider community (medicine, agriculture and environment). This compilation emphasises the utility of the information being generated from research with these mammals to the wider scientific community.

This Book Teaches Students About What A Marsupial Is, The Gestation Period, How They Raise Their Young, And Whether They Are Carnivores, Omnivores, Or Herbivores.

"The extraordinary story of these fascinating animals, A Fragile Balance, provides up-to-date information on marsupials without losing sight of the unique set of circumstances that led them to diversify Down Under. Covering all marsupial species in Australia, the book uses an evolutionary and natural history framework to interpret their biological traits. The general chapters on biology, evolution, natural history, cultural history and conservation are bounded by feature treatments of six species of note. A Fragile Balance is the first book to emphasize interactions among marsupials, and between marsupials and their environment, as well as between humans and marsupials. The text is completed by accounts of all known species, each including a basic biological and ecological description, a range map and a measure of conservation status."--BOOK JACKET.
