2. 1. Competition, Coexistence and Character Displacement : In a Young Avian Hybrid Zone

   Author : Niclas Vallin; Anna Qvarnström; Andrew Hendry; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Competition; coexistence; hybridization; ecological speciation; character displacement; pied flycatcher; collared flycatcher; Biology; Biologi; Animal Ecology; Zooekologi;

   Abstract : 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. READ MORE

4. 2. Genetic Sequence Analysis by Microarray Technology

   Author : Emilie Hultin; Joakim Lundeberg; Afshin Ahmadian; Marie Allen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Genotyping; single nucleotide polymorphism SNP ; protease-mediated allele-specific extension PrASE ; microarray; tag-array; competitive hybridization; human papillomavirus HPV ; single cell; loss of alleles; differentiation; epidermis.; Bioengineering; Bioteknik;

   Abstract : 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. READ MORE

5. 3. Arrayed identification of DNA signatures

   Author : Max Käller; Lundeberg Joakim; Mats Nilsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; apyrase; allele-specific extension; competitive hybridization; DNA sequencing; genotyping; human papillomavirus HPV ; MC1R; microarray; mutation; p53; protease; Bioengineering; Bioteknik;

   Abstract : 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. READ MORE

6. 4. Avian malaria, life-history trade-offs and interspecific competition in Ficedula flycatchers

   Author : Katarzyna Kulma; Anna Qvarnström; Marlene Zuk; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Blood parasites; competitive asymmetry; immunocompetence; interspecific competition; life-history trade-offs; MHC; parasite-driven selection;

   Abstract : 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. READ MORE

7. 5. Microbial Community Assembly during Aerobic Granulation

   Author : Raquel Liebana; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aerobic granular sludge; granulation; washout dynamics; membrane bioreactors; sequencing batch reactors; fluorescence in-situ hybridization; microbial community dynamics; reproducibility;

   Abstract : 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. READ MORE
