    Abstract : This doctoral thesis examines various factors associated with subjective well-being (SWB) in an adult Swedish population, aged 20-64 years, using cross-sectional and longitudinal data. The thesis includes four studies based on the PART study, a current population-based study on mental health, work, and relations in Stockholm County, Sweden. READ MORE

  5. 3. 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

  6. 4. 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

  7. 5. Finding fitness : empirical and theoretical explorations of inferring fitness effects from population-level SNP data

    Author : Bea Angelica Andersson; Xiao-Ru Wang; Åke Brännström; Tanja Slotte; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; distribution of fitness effects; site frequency spectra; missing data filtering; downsampling; imputation; sample size; population structure; inbreeding; selfing; homozygosity; Arabidopsis; Pinus; DFE-alpha; SLiM; population genomics; adaptation; biology; biologi; evolutionär genetik; evolutionary genetics; populationsbiologi; Population Biology; molekylärbiologi; Molecular Biology; Genetics; genetik;

    Abstract : The distribution of fitness effects (DFE) describes the likelihood that a new mutation has a specific effect on the fitness of an individual in a given population. The shape of the DFE is a result of several factors such as population size, mating system and selective environment, and can in turn influence the evolutionary potential of a species. READ MORE
