  1. 1. Buellia species with pluriseptate spores and the Physciaceae (Lecanorales, Ascomycotina) : Taxonomic, phylogenetic and ultrastructural studies

    Författare :Anders Nordin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Buellia; Diplotomma; phylogenetic analysis; pluriseptate spores; Physciaceae; taxonomy; ultrastructure; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; systematisk botanik; Systematic Botany;

    Sammanfattning : This dissertation is primarily focused on the Buellia species with pluriseptate spores, often referred to the section or genus Diplotomma, and secondarily on the Physciaceae. An ultrastructural study at family level gives new information on spore characters. LÄS MER

  3. 2. Phylogeny and species delimitation in Roccellaceae and Physciaceae (Euascomycetes)

    Författare :Katileena Lohtander; Mats Wedin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systematics and phylogenetics; Systematik och fylogeni; systematisk botanik; Systematic Botany;

    Sammanfattning : DNA sequence data (the ITS region and Group I Introns) from the nuclear ribosomal repeat (rDNA), partial β-tubulin gene sequences, RAPD markers, and some morphological characters were analysed phylogenetically in order to examine relationships in lichenized Euascomycetes, from the species level to higher taxonomic levels. The species level studies comprise some so-called species pairs in two families, Roccellaceae (Arthoniales) and Physciaceae (Lecanorales). LÄS MER

  4. 3. Phylogenetic and ecological studies in lichenology : including studies of both mycobiont and photobiont

    Författare :Åsa Dahlkild; Anders Tehler; Ingvar Kärnefelt; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phylogeny; ecology; lichen; photobiont; mycobiont; Systematics and phylogenetics; Systematik och fylogeni;

    Sammanfattning : In this thesis different aspects in lichens are investigated, namely, the phylogeny of mycobiont and photobiont, and ecology in the form of species richness of certain habitats of the Uppland province, Sweden.Analyses of ITS sequences of the lichenized fungi genus Roccella (Roccellaceae) provide an intrageneric topology of the genus with emphasis on the European, Mediterranean and Macaronesian species.
