  1. 21. 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. 22. Tracing History : Phylogenetic, Taxonomic, and Biogeographic Research in the Colchicum Family

    Författare :Annika Vinnersten; Kåre Bremer; Bertil Nordenstam; Jerrold I Davis; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; biogeography; Colchicaceae; colchicine; dating; phylogeny; taxonomy; Biologi; Biology; Biologi;

    Sammanfattning : This thesis concerns the history and the intrafamilial delimitations of the plant family Colchicaceae. A phylogeny of 73 taxa representing all genera of Colchicaceae, except the monotypic Kuntheria, is presented. LÄS MER

    Sammanfattning : Tuber aestivum is an ectomycorrhizal ascomycete with underground fruit bodies. It is an economically important species, but has been regarded as endangered in Sweden. My inventory has increased the number of reported localities from 3 to 31. It has long been debated whether T. LÄS MER

  7. 25. Reticulate Evolution in Diphasiastrum (Lycopodiaceae)

    Författare :Sunniva Margrethe Due Aagaard; Niklas Wikström; Tom A. Ranker; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; admixture analysis; Bayesian clustering; Diphasiastrum; Feulgen DNA image densitometry; homoploid hybridization; Lycopodiaceae; phylogenetic analysis; polyploidy; reticulate evolution; Systematics and phylogenetics; Systematik och fylogeni; systematisk botanik; Systematic Botany;

    Sammanfattning : In this thesis relationships and the occurrence of reticulate evolutionary events in the club moss genus Diphasiastrum are investigated. Diphasiastrum is initially established as a monophyletic group within Lycopodiaceae using non recombinant chloroplast sequence data. LÄS MER
