6. Biological Markers of Fertility
Sammanfattning : Infertility affects 15 % of couples, which corresponds to 60 - 80 million worldwide. The microenvironments in which the oocyte, embryo and fetus mature are vital to the establishment and development of a healthy pregnancy. LÄS MER
7. Contributions to the understanding of diversity and evolution in the genus Coreomyces
Sammanfattning : 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. LÄS MER
8. Mine the Gaps : Evolution of Eukaryotic Protein Indels and their Application for Testing Deep Phylogeny
Sammanfattning : Insertions/deletions (indels) are potentially powerful evolutionary markers, but little is known about their evolution and few tools exist to effectively study them. To address this, I developed SeqFIRE, a tool for automated identification and extraction of indels from protein multiple sequence alignments. LÄS MER
9. Seaweed Invasions and Novel Chemical Defences
Sammanfattning : Biological invasions pose a risk to the biodiversity and the functioning of ecosystems in invaded areas. The reasons why some introduced species become dominant and widespread in their new environments is still largely an unsettled question. LÄS MER
10. Brain Aromatase in the guppy, Poecilia reticulata : Distribution, control and role in behaviour
Sammanfattning : Oestrogens are produced by aromatisation of androgens by the aromatase enzyme. In the vertebrate brain this synthesis has vital functions in nerve protection, cell proliferation and nerve development during injury respectively brain development. LÄS MER
