  2. 6. Distribution and abundance of genetic variation in the arctic fox

    Author : Love Dalén; Anders Angerbjörn; Robert K. Wayne; Stockholms universitet; []
    Keywords : population genetics; DNA; ecology; population history; gene flow; Alopex lagopus;

    Abstract : This thesis investigates how changes in population size and spatial movements of individuals have shaped the distribution and abundance of neutral genetic variation in the arctic fox. This is done through mitochondrial and microsatellite DNA analyses on samples covering most of the species’ distribution, but with special emphasis on Scandinavia. READ MORE

  4. 7. Population genetic studies of psoriasis

    Author : Annica Inerot; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; psoriasis; population genetics; age of onset; family studies; associated diseases; clinical examination; arthritis; HLA-Cw6;

    Abstract : Psoriasis is a genetically determined, common skin disease affecting about 3 % of the population. The inheritance pattern has earlier been unclear. In collaboration with the Swedish Psoriasis Association, we have collected information on the occurrence of psoriasis in the families of 11,366 members of the Association. READ MORE

  5. 8. Growth and decline in rural Sweden : geographical distribution of employment and population 1960–2010

    Author : Martin Hedlund; Linda Lundmark; Emma Lundholm; Olof Stjernström; Kjell Overvåg; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; rural restructuring; rural heterogeneity; manufacturing decline; agricultural decline; urbanization; rural typology; life-course perspective; cluster analysis; Sweden; Social and Economic Geography; kulturgeografi;

    Abstract : This thesis investigates the combination of changes in the population and employment into sectors in rural Sweden for the period 1960-2010. The aim is to describe and analyze the demographic changes together with the labour market changes, and to account for the spatial outcome of these changes by considering the heterogeneity of rural areas.

  6. 9. Population-level consequences of variation

    Author : Lena Wennersten; Anders Forsman; Olof Leimar; Deepa Agashe; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; colour polymorphism; diversity; establishment success; evolutionary changes; population-level consequences; predation risk; Tetrix subulata; variation; Evolutionary Biology; Evolutionsbiologi;

    Abstract : Consequences of within population variation have recently attracted an increased interest in evolutionary ecology research. Theoretical models suggest important population-level consequences, but many of these predictions still remain to be tested. READ MORE

  7. 10. Population Genetics of Human Genomic Elements

    Author : Thijessen Naidoo; Mattias Jakobsson; Guillaume Achaz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; population genetics; human genome; functional elements; natural selection; pseudogenes; loss-of-function; gene regulation; Y chromosome; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Abstract : The genomes of living organisms are composed of a multitude of functional units, which interact with each other and their environment in a highly regulated fashion, to facilitate the expression of an enduring (and evolving) phenotype. Several approaches have emerged in the effort to identify these functional units and explore their activities. READ MORE
