11. Contributions to the understanding of diversity and evolution in the genus Coreomyces
Abstract : The Laboulbeniales is an order of enigmatic ascomycete fungi that are obligate microscopic parasites of arthropods, which are usually non-detrimental. They typically display a high degree of host specificity, and the genus Coreomyces, which is the recurring theme of this thesis, is no exception. READ MORE

12. Factors Influencing Evolution to Antimalarial Drug Resistance in Plasmodium falciparum in Sudan and The Gambia
Abstract : Drug resistance is a major obstacle to management and control of malaria and currently progressing at a rapid rate across Africa. This thesis has examined factors influencing evolution of resistant P. falciparum at two sites in Africa, including parasite migration, cross mating and fitness cost of resistance. READ MORE

13. Effects of Post-Glacial Range Expansions and Population Bottlenecks on Species Richness
Abstract : This thesis relates modern speciation theory to the effects of sudden changes in the range and size of populations. Special reference is made to the climatic oscillations during the Quaternary ice ages. READ MORE

14. Neurospora tetrasperma from Natural Populations : Toward the Population Genomics of a Model Fungus
Abstract : The study of DNA sequence variation is a powerful approach to study genome evolution, and to reconstruct evolutionary histories of species. In this thesis, I have studied genetic variation in the fungus Neurospora tetrasperma and other closely related Neurospora species. I have focused on N. READ MORE

15. Histone deacetylases and their co-regulators in schizosaccharomyces pombe
Abstract : The DNA in every eukaryotic cell is wrapped around eight core histones to form the nucleosome. Therefore all events that involve DNA must also involve chromatin and nucleosomes. By regulating chromatin structure the cell can regulate the reactivity of the DNA. READ MORE
