  2. 1. Complex disease genetics : Utilising targeted sequencing and homogeneous ancestry

    Author : Argyri Mathioudaki; Kerstin Lindblad-Toh; Panagiotis Deloukas; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ankylosing spondylitis; breast cancer; targeted sequencing; Sweden; genetics; population stratification.; Molekylär genetik; Molecular Genetics;

    Abstract : The complex disease investigations presented in this thesis aimed to provide new information regarding underlying genetics by using targeted sequencing and ethnically homogeneous cohorts. This work moved past current methodologies and addressed data stratification issues, that might have been hindering new findings.

  4. 2. Functional genomics of diapause in two temperate butterflies

    Author : Peter Pruisscher; Karl Gotthard; Dieter Ebert; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diapause induction; adaptation; genomics; transcriptomics; populationsgenetik; Population Genetics;

    Abstract : Natural selection will act on a given phenotype to maximize fitness in a particular environment, even if this would result in reduced fitness in other environments. In insects some of the strongest selection pressures act on timing life cycles to seasonal variation in environmental conditions, in order to maximize growth, reproduction, and to anticipate the onset of winter.

  5. 3. Immunity & the butterfly : A functional genomic study of natural variation in immunity

    Author : Naomi L.P. Keehnen; Christopher W. Wheat; Brian Lazzaro; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; eco-immunology; functional genomics; transcriptomics; innate immunity; selection dynamics; melanization; phagocytosis; population genetics; Pieris napi; populationsgenetik; Population Genetics;

    Abstract : Butterflies are ubiquitous and abundant, occurring in a wide variety of environments that contain diverse microbial communities with varied pathogenic pressures. These pathogens and parasites present a constant threat to organisms, and have led to the evolution of complex and intricate immune responses. READ MORE

  6. 4. From geography to genes: evolutionary perspectives on salinity tolerance in the brackish water barnacle Balanus improvisus

    Author : Anna-Lisa Wrange; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; environmental change; salinity; marine; invertebrates; evolution; plasticity; population genetics; functional genomics; barnacle; osmoregulation;

    Abstract : How species respond to changes in their environment is a fundamental question in biology. This has become an increasingly important issue as anthropogenic effects of climate change and biological invasions have major impacts on marine ecosystems worldwide. READ MORE

  7. 5. Dynamics of inbreeding and genetic rescue in a small population

    Author : Malin Hasselgren; Karin Norén; Carles Vilà; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; inbreeding; inbreeding depression; genetic rescue; fitness; genomics; conservation genetics; mutational load; arctic fox; pedigree; gene flow; zoologisk ekologi; Animal Ecology;

    Abstract : Isolation at small population size can reduce individual fitness and impede population growth caused by inbreeding and genetic drift (i.e. inbreeding depression). Inbreeding depression can however be circumvented by gene flow from unrelated individuals through masking of recessive deleterious alleles and contribute to population persistence (i. READ MORE
