    Sammanfattning : The Laboulbeniales is an order of enigmatic ascomycete fungi that are obligate microscopic parasites of arthropods, which are usually non-detrimental. They typically display a high degree of host specificity, and the genus Coreomyces, which is the recurring theme of this thesis, is no exception. LÄS MER

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

    Författare :Ding He; Sandra Baldauf; Siv Andersson; Andrew Roger; Uppsala universitet; []
    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

  4. 3. The Genus Amomum (Zingiberaceae) in Cambodia, Laos and Vietnam : Taxonomy and Ethnobotany, with Special Emphasis on Women's Health

    Författare :Vichith Lamxay; Lars Björk; Axel Dalberg Poulsen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Amomum; Zingiberaceae; Flore du Cambodge du Laos et du Vietnam; Taxonomy; Ethnobotany; Postpartum; Mother roasting; Hotbed; Brou; Saek; Kry; Lao PDR; Organism biology; Organismbiologi; Systematics and phylogenetics; Systematik och fylogeni; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    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

  5. 4. Spikemoss patterns : Systematics and historical biogeography of Selaginellaceae

    Författare :Stina Weststrand; Petra Korall; Michael J. Donoghue; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; classification; historical biogeography; lycophytes; nomenclature; phylogeny; Selaginella; Selaginellaceae; systematics; fylogeni; historisk biogeografi; klassifikation; lummerväxter; nomenklatur; Selaginella; Selaginellaceae; systematik; Biologi med inriktning mot systematik; Biology with specialization in Systematics;

    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

  7. 5. Patterns and Processes of Evolution in Sundaland

    Författare :Robert-Jan den Tex; Jennifer A. Leonard; Lawrence R. Heaney; Uppsala universitet; []

    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
