  2. 11. Taxonomy and phylogeny of Dermatocarpon (Verrucariales, lichenized Ascomycotina) with special emphasis on the Nordic species

    Author : Starri Heidmarsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Dermatocarpon; ITS rDNA; Morphology; Nordic countries; Phylogenetic analysis; Taxonomy; Verrucariaceae; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; systematisk botanik; Systematic Botany;

    Abstract : In this thesis Dermatocarpon (Verrucariales, lichenized Ascomycotina) of the Nordic countries is revised. Useful characters for species identification are epinecral layer type, spore length, medulla sensitivity to Melzer´s Reagent, and lower surface colour anappearance. READ MORE

  4. 12. Molecular Classification of Bladder Cancer

    Author : Gottfrid Sjödahl; Bröstcancer-genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bladder cancer; Subtype; Classification;

    Abstract : Decisions in the treatment of bladder cancer today are based on clinical and pathological risk variables such as tumor stage and tumor grade. The importance of these conventional risk variables is well documented since more than 10 years, and they are used routinely in the clinics. READ MORE

  5. 13. Taxonomy and phylogeny of polychaetes

    Author : Jenny Eklöf; Göteborgs universitet; []
    Keywords : Polychaeta; Phyllodocidae; Alciopidae; pelagic polychaetes; phylogeny; cryptic species;

    Abstract : Polychaetes are a large group of segmented worms that display an enormous morphological diversity. Molecular data has shown in recent years that groups previously thought to be separate from polychaetes are actually part of the group. READ MORE

  6. 14. Disentangling Lecania

    Author : Rikke Reese Næsborg; Leif Tibell; Stefan Ekman; Bengt Oxelman; Christian Printzen; Uppsala universitet; []
    Keywords : Biology; Crustose lichens; Phylogeny; Taxonomy; Morphology; New species; Phylogenetic diversity; Rare species; ITS; mt-SSU; RPB2; IGS; Biologi; Lecania; Ramalinaceae;

    Abstract : This thesis focuses on phylogenetic, taxonomic, ecological, and conservation aspects of the crustose lichen genus Lecania (Ramalinaceae, lichenized Ascomycota). Lecania has previously been defined on basis of relatively few morphological characters, and the genus had never been treated in molecular phylogenies. READ MORE

  7. 15. Evolution and biodiversity of the Ixoroideae (Rubiaceae)

    Author : Kent Kainulainen; Birgitta Bremer; Sylvain Razafimandimbison; Torsten Eriksson; Sandra Knapp; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alberteae; character evolution; classification; Condamineeae; fruit evolution; Ixoroideae; phylogenetics; pollen presentation; Rubiaceae; systematics; taxonomy; Systematics and phylogenetics; Systematik och fylogeni; växtsystematik; Plant Systematics;

    Abstract : The phylogenetic relationships within subfamily Ixoroideae of the coffee family are investigated by phylogenetic reconstruction of molecular data, including regions of the chloroplast DNA (matK, ndhF, rbcL, rps16, trnH-psbA, trnS-G, and trnT-F), and the nuclear ribosomal DNA (ITS). The evolution of morphological characters within the group are inferred, with focus on characters used in classification. READ MORE
