Abstract:
This thesis concerns the molecular phylogenetics of three tribes of the family Bovidae, the Antilopini, Neotragini, and Tragelaphini. None of these tribes have been studied extensively with molecular techniques. The tribe Antilopini is one of the most speciose tribes (it includes 6 genera with 20 species) and the classification of several species of the genus Gazella is not clear. The tribe Neotragini is thought to be paraphyletic. Mitochondrial sequences of the cytochrome c oxidase ill and cytochrome b genes totalling 1083 base pairs have been determined for 52 taxa and used to determine phyl

Thesis (MSc)--Stellenbosch University, 2003.<br>ENGLISH ABSTRACT: The evolutionary history of the African tribe Tragelaphini (spiral-horn antelope) is controversial. Past phylogenetic relationships among species were based on morphology or limited fossil evidence and are in conflict with mitochondrial DNA sequencing studies that have been conducted more recently. Although the group is distinguished from other African ungulates by the presence of spirally-twisted horns, the nine recognized extant species differ considerably in morphology, feeding habits and their habitat preference.

Both insect parasitic/entomopathogenic nematodes and plant parasitic nematodes are of great economic importance. Insect parasitic/entomopathogenic nematodes provide an environmentally safe and effective method to control numerous insect pests worldwide. Alternatively, plant parasitic nematodes cause billions of dollars in crop loss worldwide. Because of these impacts, it is important to understand how these nematodes evolve, and, in the case of entomopathogenic nematodes, how their bacterial symbionts evolve.

Although the size of centromeres differs between organisms, its organization, and the placement of euchromatic and heterochromatic regions is conserved from the fission yeast, Schizosaccharomyces pombe, to humans, Homo sapiens.

Fossils are needed to calibrate the molecular clock used for dating phylogenies. This has led to a re-examination of the identification and phylogenetic placement of fossils used for calibration.

Consequently, taxonomy of extant pollen has also been neglected, and this applies particularly to the pollen of Myrtaceae, which was last fully revised in the 1950s.
