  1. 1. Spikemoss patterns Systematics and historical biogeography of Selaginellaceae

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Stina Weststrand; Petra Korall; Michael J. Donoghue; [2016]

    Sammanfattning : Selaginellaceae, spikemosses, is a heterosporous plant family belonging to the lycophytes. With an estimated age of some 350 million years, the family is historically important as one of the oldest known groups of vascular plants. Selaginellaceae is herbaceous with a worldwide distribution. However, the majority of the ca. LÄS MER

  2. 2. Mine the Gaps Evolution of Eukaryotic Protein Indels and their Application for Testing Deep Phylogeny

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Pravech Ajawatanawong; Sandra Baldauf; James McInerney; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; indel; insertion deletion; protein evolution; bioinformatics; non-bilateria; eukaryotes; phylogeny; Biology with specialization in Systematics; Biologi med inriktning mot systematik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : Insertions/deletions (indels) are potentially powerful evolutionary markers, but little is known about their evolution and few tools exist to effectively study them. To address this, I developed SeqFIRE, a tool for automated identification and extraction of indels from protein multiple sequence alignments. LÄS MER

  3. 3. Patterns and Processes of Evolution in Sundaland

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; NATURAL SCIENCES Biology Organism biology Systematics and phylogenetics; NATURVETENSKAP Biologi Organismbiologi Systematik och fylogeni; NATURAL SCIENCES Biology Cell and molecular biology Genetics; NATURVETENSKAP Biologi Cell- och molekylärbiologi Genetik; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Biodiversity in the tropics is disproportionately high compared to other habitats, and also under disproportionate threat from human impact. It is necessary to understand how this diversity evolved and how it is partitioned across space in order to preserve it. LÄS MER

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ding He; Sandra Baldauf; Siv Andersson; Andrew Roger; [2014]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : The species of Amomum Roxb. (Zingiberaceae) in Cambodia, Laos and Vietnam are revised. Thirty-five species and two varieties are recognised, all names are typified, and detailed descriptions and a key are provided. Nine new species are described and one species is validated. LÄS MER
