  2. 1. Evolutionary transitions across the tree of life : Phylogenomic case studies in environmental archaea, bacteria and eukaryotes

    Author : Max Emil Schön; Thijs J. G. Ettema; Fabien Burki; David Moreira; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Evolutionary transitions; environmental sequencing; metagenomics; single-cell genomics; phylogenomics; haloarchaea; Hikarchaeia; Rickettsiales; Picozoa; plastid evolution; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : Microbes form the majority of life on Earth, but have been systematically underrepresented in historical research. The sequencing revolutions of the last two decades have completely changed the way we can study microbial genomic information, giving us the means to probe ever deeper into their evolution.

  4. 2. Face to face with the absent Buddha : The formation of Buddhist Aniconic art

    Author : Klemens Karlsson; Uppsala universitet; []
    Keywords : HUMANIORA; HUMANITIES; Buddhist art; Buddhist sculpture; Aniconic art; Indian art; Iconology; Buddhism; Buddhist meditation; History of religion; Religionshistoria;

    Abstract : Early art in Buddhist cultic sites was characterized by the absence of anthropomorphicimages of the Buddha. The Buddha was instead represented by different signs, like awheel, a tree, a seat and footprints. READ MORE

  5. 3. Climate impact of the sustainable use of forest biomass in energy and material system : a life cycle perspective

    Author : Sylvia Haus; Johan Bergh; Bishnu Chandra Poudel; Krushna Mahapatra; Göran Berndes; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest residues; fossil fuel substitution; forest management; radiative forcing; land use change; climate change; bioenergy; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology; Byggteknik; Civil engineering;

    Abstract : Human society releases greenhouse gas emissions to the atmosphere while providing housing, heat, mobility and industrial production. Man-made greenhouse gas emissions are the main causes of climate change, coming mainly from burning fossil fuels and land-use changes. READ MORE

  6. 4. Inferring Ancestry : Mitochondrial Origins and Other Deep Branches in the Eukaryote Tree of Life

    Author : Ding He; Sandra Baldauf; Siv Andersson; Andrew Roger; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular Phylogeny; Phylogenomics; Mitochondria; Eukaryote tree of life; Biology with specialization in Systematics; Biologi med inriktning mot systematik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : There are ~12 supergroups of complex-celled organisms (eukaryotes), but relationships among them (including the root) remain elusive. For Paper I, I developed a dataset of 37 eukaryotic proteins of bacterial origin (euBac), representing the conservative protein core of the proto-mitochondrion. READ MORE

  7. 5. The evolution of the nuclear envelope

    Author : Nadja Neumann; Anthony Poole; Gáspár Jékely; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear pore complex; bouquet; meiosis; nucleus; eukaryote evolution; nucleoporin; tree of life; stem group; recombination; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Abstract : The nucleus is one of the defining features of eukaryotes and the question of its origin is intimately linked to the evolution of the eukaryotic cell. It is delimited by a double lipid bilayer called the nuclear envelope, which separates the nuclear interior from the cytoplasm. READ MORE
