Book Description
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.

Book Description
Marsupial Biology developed from contributions commissioned from those attending an international symposium held in honour of Hugh Tyndale Biscoe, Australia's most celebrated marsupial biology authority and co-author of the previous leading marsupial biology text published more than 15 years ago. The book does not comprise papers of narrow focus read at the symposium, but chapters reviewing the knowledge in each key area, written to a book format. It has been tightly edited to ensure a great degree of harmony and is suitable as a comprehensive reference text for graduate and undergraduate students.

Book Description
In 1964, the Fertilization and Gamete Physiology Research Training Program (FERGAP) was established at the Marine Biological Laboratories, Woods Hole, Massachusetts. Over the course of the next 12 years, under the directorship of Dr. Charles B. Metz, FERGAP brought together, trained, and inspired a generation of students in reproductive biology from all over the world. As students of C. B. Metz and as FERGAP trainees, we would like to dedicate this collected work on comparative mammalian fertilization to our teacher and mentor, Dr. Charles B. Metz. Like a number of authors contributing to this volume, we have been struck by the significant impact that C. B. Metz and FERGAP had on the development of students of reproductive biology. Applying both the classical and molecular techniques of cell biology and immunology to problems of gamete biology, Dr. Metz emphasized a comparative and analytical approach that was reflected in his own research on fertilization in Paramecia, sea urchins, frogs, and mammals. It is hoped that this volume will serve to stimulate students to discover the myriad of fascinating research problems in gamete and reproductive biology. Bonnie S. Dunbar Michael G.

Book Description
With the expansion of human settlements and the environmental changes brought on by human activity and pollutants toxicology and risk assessment of mammal species is becoming increasingly of interest to toxicologists involved in environmental research. This book focuses specifically on environmental risk assessment in marsupial and placental mammals. Marsupial ecotoxicology is poorly understood in scientific research and as such environmental risk assessment in marsupials is an area of rapidly growing interest. This book will be an ideal companion to toxicologists and ecologists interested in risk assessment in the environments of mammals. Particularly those with an interest in the impact introduced by human activity. The book will also be of interest to those working in conservation biology, biological invasion, biocontrol and habitat management.

Book Description
Marsupials belong to the Class Mammalia, sharing some features with other mammals, yet they also possess many unique features. It is their differences from the more traditionally studied mammals, such as mice and humans, that is of greatest value to comparative studies. Sequencing of genomes from two distantly related marsupials, the short grey-tailed opossum from South America and the Australian tammar wallaby, has launched marsupials into the genomics era and accelerated the rate of progress in marsupial research. With the current worldwide concern for the plight of the endangered Tasmanian devil, marsupial genetics and genomics research is even more important than ever if this species is to be saved from extinction. This volume recounts some of the history of research in this field and highlights the most recent advances in the many different areas of marsupial genetics and genomics research.

Book Description
Australian marsupials represent a parallel adaptive radiation to that seen among placental mammals. This great natural experiment has produced a striking array of mammals with structural and behavioural features echoing those seen among primates, rodents, carnivores, edentates and ungulates elsewhere in the world. Many of these adaptations involve profound evolutionary changes in the nervous system, and occurred in isolation from those unfolding among placental mammals. Ashwell provides the first comprehensive review of the scientific literature on the structure and function of the nervous system of Australian marsupials. The book also includes the first comprehensive delineated atlases of brain structure in a representative diprotodont marsupial (the tammar wallaby) and a representative polyprotodont marsupial (the stripe-faced dunnart). For those interested in brain development, the book also provides the first comprehensive delineated atlas of brain development in a diprotodont marsupial (the tammar wallaby) during the critical first 4 weeks of pouch life.

Book Description
Authoritative and engaging, this volume from the Walker's Mammals series focuses on marsupials, pouched animals whose unusual method of reproduction—between egg laying and placental birth—places them in a unique category among mammals. A comprehensive guide to the biology and distribution of marsupials, this book includes common and scientific names, size and physical traits, habitat and ecology, behavior and social interactions, reproduction, life span, and conservation. The text is coupled with illustrations from the collections of leading photographers and the world's greatest museums. An introduction by marsupial expert Christopher R. Dickman describes the evolution and current status of marsupials and reveals why they add so much intrigue to the natural world.

Book Description
This book focuses on the evolution, biogeography, systematics, taxonomy, and ecology of New World and Australasian marsupials, greatly expanding the current knowledge base. There are roughly 140 species of New World marsupials, of which the opossum is the best known. Thanks to recent research, there is now an increasing amount of understanding about their evolution, biogeography, systematics, ecology, and conservation in the Americas, especially in South America. There are also some 270 marsupial species in the Australasian region, many of which have been subject to research only in recent years. Based on this information and the authors’ extensive research, this book provides comprehensive insights into the world's marsupials. It will appeal to academics and specialized researchers, students of zoology, paleontology, evolutionary biology, ecology, physiology and conservation as well as interested non-experts.
