  1. 1. Evolution of streamlined genomes in ultra-small aquatic bacteria

    Författare :Weizhou Zhao; Siv Andersson; Sandra L. Baldauf; Sarahi L Garcia; Karen Lloyd; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; streamlined genome; aquatic bacteria; single cell genomics; metagenomics; evolutionary genomics; salinity; Baltic Sea; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : This thesis investigates the evolutionary processes of streamlined genomes from aquatic bacteria adapting to different salinities, using two groups of ultra-small aquatic bacteria (LD12 Alphaproteobacteria and acI Actinobacteria). Due to difficulties in obtaining pure cultures of these bacteria, culture-free approaches (single-cell genomics and metagenomics) were used to construct and compare genomes, and to study the mechanisms and selective forces of adaptation to freshwater, brackish, and marine ecosystems.

  3. 2. Fish population responses to climate change : Causes and consequences

    Författare :Matilda L. Andersson; Peter Eklöv; Brian Hayden; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; browning; climate change; DOC; intraspecific variation; metabolism; resource use; warming;

    Sammanfattning : Lake environments are heterogeneous, and animals show a variety of adaptations to deal with this heterogeneity. Fish often show intraspecific variation in diet, metabolism, and behavior, corresponding to their habitat use. LÄS MER

  5. 4. Predicting Health Behaviour – Population-Based Studies of Knowledge and Behaviour Related to Cardiovascular Diseases

    Författare :Per Andersson; Jerzy Leppert; Rickard L Sjöberg; Mai-Lis Hellénius; Uppsala universitet; []
    Nyckelord :Public health; Population-based study; knowledge about risk factors; CVD; predicting behaviour; family history; experience of illness; obesity; comparison Sweden - Poland; stage of change; health belief model; Folkhälsomedicin;

    Sammanfattning : The overall aim was to study factors that affect behaviour related to CVD (cardiovascular diseases). Study I tested whether gender, education and so-cioeconomic status correlated to knowledge about risk factors, and Study II studied knowledge and risk behaviour from a national perspective (Sweden versus Poland).
