  1. 1. Phylogeny and Taxonomy of Polyblastia and allied taxa (Verrucariaceae)

    Författare :Sanja Savić; Leif Tibell; Bengt Oxelman; Martin Grube; Uppsala universitet; []
    Nyckelord :Biology; Phylogeny; Taxonomy; ITS; LSU; RPB1; Nomenclature; Biologi; Polyblastia; Verrucariaceae; Sporodictyon; Atla; Thelidium; Verrucaria; Staurothele; Trimmatothele;

    Sammanfattning : Polyblastia A. Massal. is a genus of lichenized fungi belonging to Verrucariaceae (Ascomycota). Traditional classification heavily rested on a few cardinal characters, primarily ascoma structure and spore morphology, but the delimitation of Polyblastia was problematic. LÄS MER

  3. 2. Phylogenetic Studies in Usnea (Parmeliaceae) and Allied Genera

    Författare :Kristina Articus; Leif Tibell; Mats Wedin; Jan-Eric Mattsson; Philippe Clerc; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Usnea; Neuropogon; Dolichousnea; Eumitria; Protousnea; Parmeliaceae; phylogeny; taxonomy; species pairs; morphology; ITS-LSU; β-tubulin; mtSSU; Biologi; Biology; Biologi;

    Sammanfattning : This thesis deals with the phylogeny of the lichen genus Usnea (Parmeliaceae, Ascomycetes). The relationships and the morphological variation among Usnea species has been studied, as well as the relationship of Usnea to allied genera. Two species, U. florida and U. LÄS MER

  4. 3. Detection and identification of Pneumocystis carinii-DNA : emphasis on laboratory diagnosis and occurrence in air

    Författare :Mats Olsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Pneumocystis carinii; PCP; PCR; diagnosis; genotyping; air filtration.;

    Sammanfattning : Pneumocystis carinii is a fungal opportunistic pathogen, which causes serious pneumonia (P. carinii pneumonia - PCP) in patients with AIDS, leukaemia, and other immunodeficient conditions. The laboratory diagnosis is dependant on microscopic demonstration of the organism. LÄS MER

  5. 4. The Dawn of a New Age : Interrelationships of Acoela and Nemertodermatida and the Early Evolution of Bilateria

    Författare :Andreas Wallberg; Ulf Jondelius; Mikael Thollesson; Graham Budd; Gonzalo Giribet; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acoela; Nemertodermatida; Bilateria; Metazoa; evolution; phylogenetic inferrence; ancestral reconstruction; taxon sampling; microRNA; Systematics and phylogenetics; Systematik och fylogeni; systematisk zoologi; Systematic Zoology;

    Sammanfattning : Deciphering the rapid emergence of bilaterian animals around the time of the Cambrian Explosion and reconstructing the interrelationships of animal groups have long been two of the most elusive problems in Zoology. This thesis concerns the phylogenetic interrelationships within and among Acoela and Nemertodermatida, two groups of small worms that are believed to be basal bilaterians and which may provide important clues for understanding the early evolution of animals.

  7. 5. Development of molecular techniques for fungal diagnostic research

    Författare :Qing-Yin Zeng; Åsa Rasmuson-Lestander; Xiao-Ru Wang; Aino Nevalainen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Fungi; DNA markers; Aerosols; Detection and quantification; Environmental monitoring; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Fungi are present everywhere in indoor and outdoor environments. Many fungi are toxigenic or pathogenic that may cause various public health concerns. Rapid detection, quantification and characterization of fungi in living and working environments are essential for exposure risk assessment to safe guard public health. LÄS MER
