  2. 6. Diversity Underfoot : Systematics and Biogeography of the Dictyostelid Social Amoebae

    Author : Allison L Perrigo; Sandra Baldauf; Maria Romeralo; David Bass; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Amoeba; biogeography; cryptic species; dictyostelid; latitudinal gradient; multicellularity; protist; social amoeba; phylogenetics; systematics; new species; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Abstract : Dictyostelids (Amoebozoa) are a group of social amoebae consisting of approximately 150 species, which are found in terrestrial habitats worldwide. They are divided into eight major clades based on molecular phylogeny, and within these clades are many species complexes. READ MORE

  4. 7. Engineering Yeast for the Production of Biologicals

    Author : Veronica Gast; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biopharmaceuticals; genome-scale models.; kinase Gcn2; Recombinant protein production; proteases; Saccharomyces cerevisiae; biologicals;

    Abstract : The market for biopharmaceutical proteins, or biologicals, has been expanding rapidly over the last decades and its value was estimated in 2020 to exceed 300 billion US dollars. Efficient cell factories that produce the biologicals fulfill an essential role within this industry. READ MORE

  5. 8. Exploring the Interplay of Lipids and Membrane Proteins

    Author : Candan Ariöz; Åke Wieslander; Daniel O. Daley; Malcolm East; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Membrane lipids; membrane proteins; anionic lipids; membrane remodeling; intracellular vesicles; model membrane systems; glycosyltransferase; Escherichia coli; lipid composition; fatty acid modification; membrane curvature; bacterial homeoviscous adaptation; Biochemistry; biokemi;

    Abstract : The interplay between lipids and membrane proteins is known to affect membrane protein topology and thus have significant effect (control) on their functions. In this PhD thesis, the influence of lipids on the membrane protein function was studied using three different membrane protein models. READ MORE

  6. 9. Artificial neural networks in models of specialization and sympatric speciation

    Author : Niclas Norrström; Högskolan i Skövde; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Naturvetenskap; Natural sciences;

    Abstract : This thesis deals with specialization and how it is linked to sympatric speciation. The trait driving specialization is a cue recognition trait modelled with artificial neural networks that exploiters use to discriminate beneficial resources from detrimental resources based on the signals of the resources.

  7. 10. Population viability analysis for plants : practical recommendations and applications

    Author : Satu Ramula; Kari Lehtilä; Patrik Dinnétz; Esa Ranta; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; demography; matrix population models; population viability analysis; population growth rate; stochastic models; Biology; Biologi;

    Abstract : Population viability analysis (PVA) is commonly used in conservation biology to predict population viability in terms of population growth rate and risk of extinction. However, large data requirements limit the use of PVA for many rare and threatened species. READ MORE
