Development of a transgenic strategy for facilitated modifier mutation screening in Zebrafish / Esther Maria Camp.

Camp, Esther Maria January 2003 (has links)
"April 2003" / Bibliography: p. 40-41. / 42 p. : ill. (some col.), plates (col.) ; 30 cm. / Title page, contents and abstract only. The complete thesis in print form is available from the University Library. / The aim of this study was to develop a transgenic strategy for a facilitated modifier mutation screening in zebrafish. This system represents a potentially powerful method that could be used to study the genetic interactions involved in developmental processes in a vertebrate animal. The overall aim of the project has been to create a transgenic strategy whereby a cloned developmental control gene can be abnormally but non-lethally expressed in the paired fins or melanin producing cells of transgenic zebrafish to cause a visible altered phenotype. --p. 41. / Thesis (Ph.D.)--University of Adelaide, School of Molecular and Biomedical Science, 2003

Alzheimer's disease genes in zebrafish (Danio rerio) / Casper Groth.

Groth, Casper January 2003 (has links)
"August 2003" / Bibliography: leaves 166-195. / vii, 195 leaves : ill. (col.); plates (col.) ; 30 cm. / Title page, contents and abstract only. The complete thesis in print form is available from the University Library. / It was felt that investigations of the mechanisms controlling developmental processes in different embryonic tissues may be a relevant approach in order to gain insight into the normal biological functions of Alzheimer's disease related genes, and, ultimately the cause of neurodegeneration as well as other pathological conditions in the adult. Therefore, it was decided to dissect the functions of Alzheimer's disease genes during embryo development using the zebra fish (Danio rerio) as a model organism. / Thesis (Ph.D.)--University of Adelaide, School of Molecular and Biomedial Science, Discipline of Genetics, 2004

Grevy's zebra : ecology in a heterogeneous environment

Williams, Stuart David January 1998 (has links)
The aim of this study was to test the hypothesis that Grevy's zebra (Equus grevyi Oustalet) compete for critical resources with pastoral people and their domestic livestock. The study was conducted in three areas to approximate a manipulative experiment, with pastoralists and their livestock being excluded from one of the areas. Forage was seasonally limited in the areas used by pastoralists. Although no single factor determined the space use of Grevy's zebra, the distribution of food - particularly in the pastoralist areas - and predators were important. Use of space by Grevy's zebra was constrained by their dependence on water and by the presence of the people in the pastoralist areas. Zebra dispersed from areas when food became limiting. Different sex classes exhibited different times of dispersal that may have been related to different thresholds for dispersal. In the area where there were no pastoral people, temporal patterns of water use by Grevy's zebra were driven by avoidance of predation. In contrast, Grevy's zebra in the pastoralist areas drank at night to avoid the monopolisation of water by people and their domestic livestock by day. By drinking at night, the zebra, and particularly their foals, were probably more susceptible to predation. Breeding patterns in Grevy's zebra were explained by condition dependent oestrus: oestrus and conception were highly dependent on stochastic patterns of climatic variation. Juvenile survival was related to the amount mothers move, and was lowest in areas used by pastoralists. Grevy's zebra were found to compete for critical resources with pastoralists and their livestock. This highlighted the importance of protected areas to sustain recruitment into the population. Release from competition is, however, necessary to further improve the likelihood of persistence of Grevy's zebra in their natural range. To achieve this, pastoralist stocking rates must be reduced.
