  2. 16. Hopeful monsters: The role of hybrids in adaptation : The impact of hybridisation and genetic diversity on adaptation to stressful and novel environments

    Author : Ciaran Gilchrist; Rike Stelkens; Christopher Wheat; Linda Laikre; Mathilde Cordellier; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Experimental evolution; Saccharomyces cerevisiae; population genetics; hybridisation; adaptation; aneuploidy; comparative genomics; evolve-and-resequence; de novo mutations; evolutionary parallelism; populationsgenetik; Population Genetics;

    Abstract : Adaptation to novel environments can only occur if natural selection has the raw material to act upon. But small, endangered populations are often genetically depleted, and the acquisition of beneficial de novo mutations often takes too long when population face quick and extreme environmental change.

  4. 17. Comparative studies of modern methods for caries detection and quantification

    Author : Xie-Qi Shi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : In clinical dentistry proper treatment of caries lesions is highly dependent on diagnostic accuracy. Aim: The present dissertation aimed at the evaluation and comparisons between several modem methods for caries detection and quantification. READ MORE

  5. 18. Reconciling gene family evolution and species evolution

    Author : Joel Sjöstrand; Jens Lagergren; Nicolas Lartillot; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational biology; Bioinformatics; Phylogenetics; Phylogenomics; Comparative genomics; Evolutionary biology; datalogi; Computer Science;

    Abstract : Species evolution can often be adequately described with a phylogenetic tree. Interestingly, this is the case also for the evolution of homologous genes; a gene in an ancestral species may – through gene duplication, gene loss, lateral gene transfer (LGT), and speciation events – give rise to a gene family distributed across contemporaneous species.

  6. 19. The pace of innovation : Patterns of innovation in the cardiac pacemaker industry

    Author : Patrik Hidefjäll; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cardiac Pacemaker; Competition; Competitive Advantage; Defibrillator; Dominant Design; Innovation; Organizational Field; Patterns of Innovation; Technical Change; Technology Cycle; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : The PhD thesis "The Pace of Innovation" addresses the questions how patterns of innovation change over time in an industry, their consequences for competition and how institutional conditions in an industry shape determinants of patterns of innovation. Patterns of innovation mainly refer to how certain regularities in the diversity, types and locus of innovation change in an industry according to a technology and industry life cycle. READ MORE

  7. 20. Comparative Population Ecology in Moor Frogs with Particular Reference to Acidity

    Author : Fredrik Söderman; Anssi Laurila; Jacob Höglund; Juha Merilä; J.W (Pim) Arntzen; Uppsala universitet; []
    Keywords : Biology; Amphibians; Life-history; Trade-off; Environmental stress; Local adaptation; Acidity; Biologi;

    Abstract : This thesis is an attempt to describe how different environmental factors influence life history traits in different populations, sexes and developmental stages in the moor frog, Rana arvalis. The studied populations are located along 1100 km latitudinal gradient, with pH varying between 4.0 and 8.5. READ MORE
