FERTILIZATION IN VIVO AND IN VITRO IN AUSTRALIAN MARSUPIALS. Using reproductive technology previously undeveloped in Australian marsupials this study addresses the most significant question still unresolved in marsupial reproductive biology - 'How does fertilization occur?' We propose to investigate the morphological and functional characteristics of fertilisation and its roles in early development in marsupials, the uniqueness of these events and their evolutionary significance. These findings ....FERTILIZATION IN VIVO AND IN VITRO IN AUSTRALIAN MARSUPIALS. Using reproductive technology previously undeveloped in Australian marsupials this study addresses the most significant question still unresolved in marsupial reproductive biology - 'How does fertilization occur?' We propose to investigate the morphological and functional characteristics of fertilisation and its roles in early development in marsupials, the uniqueness of these events and their evolutionary significance. These findings will not only further our knowledge of reproduction in marsupials and shed light on the evolutionary factors underlying sperm and egg design but will provide tools for assisted breeding programs for threatened wildlife and for the regulation of over abundant species.Read moreRead less
The development and evolution of the pelvic girdle in basal gnathostomes. Comparing the development of muscles, cartilage and bone in representatives of all three major groups of fish will provide information as to how structures evolved but also how the adult morphology is distributed in phylogeny. Because so little is known about the genetic mechanisms underlying the formation of the pelvic girdle in fish, it is important to start studying a model animal such as the zebrafish. The pathways unc ....The development and evolution of the pelvic girdle in basal gnathostomes. Comparing the development of muscles, cartilage and bone in representatives of all three major groups of fish will provide information as to how structures evolved but also how the adult morphology is distributed in phylogeny. Because so little is known about the genetic mechanisms underlying the formation of the pelvic girdle in fish, it is important to start studying a model animal such as the zebrafish. The pathways uncovered have the potential to describe mechanisms common to all jawed vertebrates, not only common to fish. Understanding the mechanisms that generate major morphological transition in the vertebrate lineage necessarily informs us about our own evolutionRead moreRead less
