  2. 1. Population Genetic Methods and Applications to Human Genomes

    Author : Lucie Gattepaille; Mattias Jakobsson; Kevin Thornton; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Population genetics; Human evolution; Genetic diversity; Genetic differentiation; Adaptation; Population structure; Effective population size; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Population Genetics has led to countless numbers of fruitful studies of evolution, due to its abilities for prediction and description of the most important evolutionary processes such as mutation, genetic drift and selection. The field is still growing today, with new methods and models being developed to answer questions of evolutionary relevance and to lift the veil on the past of all life forms. READ MORE

  4. 2. Changing population distribution in Sweden : long term trends and contemporary tendencies

    Author : Johan Håkansson; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Population distribution; redistribution; Sweden; geographical levels; concentration; dispersion; accessibility; migration; natural population change; age composition;

    Abstract : The aim of the thesis is to describe and analyse the population redistribution in Sweden at different geographical levels from the beginning of the 19th century to the end of the 20th century. The analysis is approached in three different ways. First, the redistribution at different geographical levels is analysed (papers I and II). READ MORE

  5. 3. Human demographic history : Insights on the human past based on genomes from Southern through Central Africa

    Author : Gwenna Breton; Mattias Jakobsson; Carina Schlebusch; Per Sjödin; Paul Verdu; David Comas; Uppsala universitet; []
    Keywords : high-coverage genomes; Sub-Saharan Africa; demography; genetic admixture; population genetics; human evolutionary genetics; Khoe-San; rainforest hunter-gatherers; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Abstract : Evidence from paleontology, archaeology and population genetics support that modern humans originated in Africa. While the out-of-Africa event and subsequent colonization of all continents are well documented, human history in Africa at that time and before is less studied. READ MORE

  6. 4. Human olfaction : Associations with longitudinal assessment of episodic memory, dementia, and mortality risk

    Author : Ingrid Ekström; Jonas Olofsson; Maria Larsson; Devangere Devanand; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; olfaction; odor identification; self-assessments; aging; episodic memory; ApoE; dementia; Alzheimer’s disease; vascular dementia; mortality; cohort study; population-based.; Psychology; psykologi;

    Abstract : A declining sense of smell is a common feature in older age. Above and beyond diminished smelling capacity due to normal processes of human aging, impairments in olfactory function have also been linked to numerous ill-health related outcomes, such as cognitive dysfunctions, dementia pathology and even an increased risk of death.

  7. 5. 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
