  2. 1. Biased Evolution : Causes and Consequences

    Author : Gerrit Brandis; Diarmaid Hughes; Erik Böttger; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Evolution; Codon usage bias; Post-transcriptional regulation; Recombination; Inversion; EF-Tu; Frameshift suppression; Antibiotic resistance; Rifampicin; Ciprofloxacin; Compensatory evolution; Drug efflux; RNA polymerase; DNA gyrase; Mikrobiologi; Microbiology;

    Abstract : In evolution alternative genetic trajectories can potentially lead to similar phenotypic outcomes. However, certain trajectories are preferred over others. These preferences bias the genomes of living organisms and the underlying processes can be observed in ongoing evolution. READ MORE

  4. 2. Encountering Evolution : Children's Meaning-Making Processes in Collaborative Interactions

    Author : Johanna Frejd; Magnus Hultén; Karin Stolpe; Konrad Schönborn; Christina Siry; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Meaning-making processes; Science Education; Evolution; Multimodality; Collaborative Interaction; Exploratory studies; Meningsskapandeprocesser; Naturvetenskapsundervisning; Evolution; Multimodalitet; Interaktion; Explorativa studier;

    Abstract : This thesis explores preschool class children’s meaning making processes when they encounter evolution. By adopting social semiotic and sociocultural perspectives on meaning making, three group-based tasks were designed. Video data from the activities were analysed using a multimodal approach.

    Abstract : Life is able to replicate itself, e.g., a microorganism is able to divide into two identical ones, and a single plant is able to forest a whole island. READ MORE

  6. 4. Mapping incomplete relational data : networks in ecology & evolution

    Author : Daniel Edler; Martin Rosvall; Alexandre Antonelli; Renaud Lambiotte; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; network science; information theory; map equation; community detection; biogeography; evolution;

    Abstract : We live in an interconnected world full of complex systems that cannot be understood simply by analyzing their components. From how genes regulate biological functions to the distribution of life on Earth, we need methods that can analyze systems as a whole. READ MORE

  7. 5. Open Government Data as a Reform and Ecosystem : A conceptual framework for evolution and health
