  1. 1. Culture-independent methods and high-throughput sequencing applied to evolutionary microbial genomics

    Författare :Anders E. Lind; Thijs JG Ettema; Purificación López-García; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Single cell genomics; metagenomics; amplicon; archaea; haloarchaea; endosymbiosis; ciliate; hydrogenosome; tree reconciliation;

    Sammanfattning : Culture-independent methods allow us to better understand the diversity of microorganisms on earth. By omitting the culturing step, we can gain access to species previously out of our reach.To better capture and understand the diversity of microorganisms, we have developed an alternative to 16S amplicon sequencing.

  2. 2. Factors controlling pelagic communities of freshwater ciliates and heliozoans

    Författare :Ulrika Stensdotter-Blomberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; ciliates; heliozoans; freshwater; nutrients; predation; microbial food web; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; limnologi; Limnology;

    Sammanfattning : Ciliate diversity and seasonal succession were studied during two years in oligotrophic,acidic Lake Njupfatet. Maximum ciliate abundance occurred shortly after ice-out. After thefirst year, the lake was neutralised by liming. Liming caused changes in the bacterioplanktonand phytoplankton communities, but no change in ciliate diversity. LÄS MER

  3. 3. Novel insights into protist diversity and niche adaptation using single cell transcriptomics

    Författare :Henning Onsbring; Thijs J. G. Ettema; Alastair Simpson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protists; microbial eukaryotes; cultivation-independent methods; single-cell RNA sequencing; phylogenomics; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : Protists are a polyphyletic group of microbes that represents the vast majority of eukaryotic diversity. Despite this, most sequencing efforts targeting eukaryotes have been focused on animals, fungi and plants. LÄS MER

  4. 4. On the Origin and Evolution of the Mitochondrial Ribosome

    Författare :Victor Tobiasson; Alexey Amunts; Loren Williams; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ribosome; mitochondria; evolution; structural biology; biokemi; Biochemistry;

    Sammanfattning : The ribosome is among the most ancient, intricate and well studied macromolecular complexes in biology. Predating the earliest divergence of life, its core molecular structure has remained mostly unchanged for more than three billion years. LÄS MER

  5. 5. Climate-induced changes : Its effects on plankton food webs from the Baltic Sea

    Författare :Claudia Romero-Oliva; Edna Graneli; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate-induced changes; temperature; acidification; marine food web; natural plankton community; spring; summer; Baltic Sea; Marine ecology; Marin ekologi; Akvatisk ekologi; Aquatic Ecology;

    Sammanfattning : The Earth’s climate is determined different processes occurring in the atmosphere, land and ocean.Anthropogenic activities (mainly combustion of fossil fuels) have increased since the 1950’s, andthus the concentration of greenhouse gases that are warming up the planet. LÄS MER
