2. 6. Evolution and host-specific adaptations of Legionella pneumophila

   Author : Anaísa B. Moreno; Lionel Guy; Dan I. Andersson; Fredrik Söderbom; Alexander W. Ensminger; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Evolution; Legionella pneumophila; host-adaptation; experimental evolution; Acanthamoeba castellanii; transfection; Mikrobiologi; Microbiology;

   Abstract : How bacteria evolve pathogenic traits is shaped by their communities and environments. Legionella pneumophila is ubiquitous in aquatic habitats, where it persists by replicating within a broad range of protozoan hosts. Using the same mechanisms, L. READ MORE

4. 7. Learning Protein Evolution and Structure

   Author : Patrick Bryant; Arne Elofsson; Paul Bates; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein structure prediction; Evolution; AI; AlphaFold; biokemi med inriktning mot bioinformatik; Biochemistry towards Bioinformatics;

   Abstract : By analysing the structure of a protein it is possible to draw conclusions about its function. Obtaining the structure of a protein experimentally is however a time consuming and expensive process. By using evolution it is possible to infer the structure of a protein. READ MORE

5. 8. Learning Mechatronics : In Collaborative, Experimental and International settings

   Author : Martin Grimheden; KTH; []
   Keywords : Mechatronics; engineering education; collaborative-; experimental-; distributed- and opportunity learning; prototype design; Mechanical engineering; Maskinteknik;

   Abstract : The academic subject of mechatronics has been definedpreviously in numerous publications. This study aims atanalyzing mechatronics by using categories developed within theeducational science of Didactics. READ MORE

6. 9. Sex Chromosome Evolution in a Hermaphrodite : Genetic and phenotypic relationships between sex roles

   Author : Anna Nordén; Evolutionär ekologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sex chromosome evolution; Hermaphrodite; Inter-sexual genetic correlation; Quantitative genetics; Macrostomum lignano; Experimental evolution; Sexual conflict;

   Abstract : Sex chromosome evolution in a hermaphrodite ancestor starts with the establishment of a sex-determining region (SDR). Over time, sex-specific genes, and/or sexually antagonistic alleles will become linked to the SDR. READ MORE

7. 10. Ecology and Evolution of Resistance to Herbivory : Trichome Production in Arabidopsis lyrata

   Author : Geir Løe; Jon Ågren; Kari Lehtilä; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Plant-animal interactions; herbivory; trichomes; plant resistance; plant defense; divergent selection; local adaptation; GLABROUS1; evolution; matrix population models; LTRE; Biologi; Biology; Biologi;

   Abstract : In this thesis, I examine variation in occurrence and performance of glabrous and trichome-producing plants of the perennial herb Arabidopsis lyrata. I combine field studies and genetic analysis to (1) examine the function of trichomes as a resistance character in natural populations, (2) compare the magnitude of population differentiation in trichome-production and at putatively neutral marker loci, (3) examine the molecular genetic basis of trichome-production, and (4) quantify the effects of herbivore removal on population growth and relative performance of glabrous and trichome-producing plants.
