1. Competition, Coexistence and Character Displacement : In a Young Avian Hybrid Zone
Sammanfattning : This thesis investigates the ecological and evolutionary implications of a recent secondary contact between two closely related bird species: collared (Ficedula albicollis) and pied (F. hypoleuca) flycatchers. LÄS MER
2. Genetic Sequence Analysis by Microarray Technology
Sammanfattning : Developments within the field of genetic analysis have during the last decade become enormous. Advances in DNA sequencing technology have increased throughput from a thousand bases to over a billion bases in a day and decreased the cost thousandfold per base. LÄS MER
3. Arrayed identification of DNA signatures
Sammanfattning : In this thesis techniques are presented that aim to determine individual DNA signatures by controlled synthesis of nucleic acid multimers. Allele-specific extension reactions with an improved specificity were applied for several genomic purposes. Since DNA polymerases extend some mismatched 3’-end primers, an improved specificity is a concern. LÄS MER
4. Avian malaria, life-history trade-offs and interspecific competition in Ficedula flycatchers
Sammanfattning : This thesis investigates the impact of avian malaria (Haemosporidia) parasites on the outcome of interspecific competition between two closely related bird species, pied (Ficedula hypoleuca) and collared (F. albicollis) flycatchers. LÄS MER
5. Microbial Community Assembly during Aerobic Granulation
Sammanfattning : Environmental deterioration together with the increasingly restrictive legislation of water quality standards have led to a demand for compact, efficient and less energy consuming technologies for wastewater treatment. Aerobic granular membrane bioreactors (AGMBRs) combine the advantages of aerobic granular sludge and membrane filtration. LÄS MER
