The Developing Marsupial


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.




Reproductive Physiology of Marsupials


Book Description

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.

The Biology of Marsupials


Book Description

The Biology of Marsupials is a compilation and analysis of the research conducted on New World marsupials that covers both Australian and didelphid marsupials. It is organized into nine chapters that aim to bring scientific community the information available on certain aspects of marsupial biology. After presenting data on karyotypes, comparative serology, classification, and phylogenetic inferences of marsupials, this book goes on discussing the organism's chromosomes, cell cycles, and cytogenetics. A chapter covers the ecological strategies and adaptations of marsupial family, particularly, of the Didelphis virginiana. Another chapter discusses marsupial neurology; evidence of commonalities with eutherian nervous systems; distinctive features peculiar to the marsupial subclass; and neural specialization identification of particular genera and species in this subclass. The following chapter describes the plasticity, variability, and generability of the behavior patterns of marsupials. This book also describes the anatomy and histologic, embryologic, and gerontologic observations of Marmosa robinsoni. The concluding chapters discuss diseases of both American and Australasian marsupials based on zoological, wildlife, parasitological, and veterinary medical studies. Supplemental texts are also provided. This book is ideal for researchers in the fields of developmental anatomy, immunology, neurology, and many aspects of comparative medicine and behavior.




Life of Marsupials


Book Description

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.




Marsupial Biology


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.

Hearing — the Brain and Auditory Communication in Marsupials


Book Description

This monograph evolved from years of research into the auditory pathway and hearing of many species of marsupials. Its function is to give biologists, in par ticular neurobiologists, a broad description and review of what is known of the auditory sensory capacities and processing mechanisms in this large order of mammals. My initial interest in marsupials developed from collaborative work with Dr. Richard Gates at Monash and Melbourne Universities in the 1970s and by curiosity as to whether concepts about the auditory system was stimulated stemming from experiments mainly on domestic cats could be extended to mam mals of other orders. My subsequent interest in Australian marsupials, aroused by collaboration with Dr. John Nelson at Monash University in the 1980s and 1990s, concerned their auditory systems and behavior per se and not as primitive cousins of eutherians. More recently, I have collaborated with Dr. Bruce Masterton at Florida State University in studies of New World marsupials. His sad death in 1996 has robbed neurobiologists of one of our most provocative thinkers and hypothesis testers. I would like to thank the Department of Physiology at Monash University for making many facilities available to me, the National Health and Medical Research of Australia and the Australian Research Council for providing funds for Council research, and Jill Poynton and Michelle Mulholland, who illustrated this volume.




The Neurobiology of Australian Marsupials


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.




Marsupial Genetics and Genomics


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.
