  1. 1. Taxonomy and Reticulate Phylogeny of Heliosperma and Related Genera (Sileneae, Caryophyllaceae)

    Detta är en avhandling från Uppsala : Universitetsbiblioteket

    Författare :Božo Frajman; Uppsala universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sileneae; Silene; Heliosperma; Atocion; Viscaria; taxonomy; phylogenetics; relative dating; reticulate evolution; chloroplast capture; homoploid hybridisation; BEAST; r8s; PATHd8; Prometheus; RPA2; RPB2; RPD2a; RPD2b; Balkan Peninsula; endemics; NATURAL SCIENCES Biology Organism biology Systematics and phylogenetics; NATURVETENSKAP Biologi Organismbiologi Systematik och fylogeni;

    Sammanfattning : Heliosperma (nom. cons prop.) comprises 15—20 taxa, most of them endemic to the Balkan Peninsula. DNA sequences from the chloroplast (rps16 intron, psbE-petG spacer) and the nuclear genome (ITS and four putatively unlinked RNA polymerase genes) are used to elucidate phylogenetic relationships within Heliosperma, and its position within Sileneae.

  2. 2. Chronic kidney disease of unknown etiology in Central America and Sri Lanka : renal morphology and clinical characteristics

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Clinical Science, Intervention and Technology

    Författare :Julia Wijkström; Karolinska Institutet.; Karolinska Institutet.; [2017]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background: Chronic kidney disease (CKD) is a global health problem. The most common etiologies of CKD are diabetes mellitus, hypertension, and glomerulonephritis, but over the last several decades a high prevalence of CKD of unknown etiology (CKDu) has been reported from rural communities in some tropical countries, including Central America, and Sri Lanka.

  3. 3. Systematics in Sileneae (Caryophyllaceae) – Taxonomy and Phylogenetic patterns

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Frida Eggens; Uppsala universitet.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sileneae; Silene; RNAP; psbE-petG; ITS; rps16; relative dating; Rigidulae; Heliosperma; Arenosae; phylogeny; homoploid reticulate evolution; Silene linearis Decne.; Silene polyphylla L.; Hawaiian Silene; NATURAL SCIENCES Biology Organism biology Systematics and phylogenetics; NATURVETENSKAP Biologi Organismbiologi Systematik och fylogeni;

    Sammanfattning : The focus for the first part of the thesis is on the systematics of species belonging to Silene subgenus Silene. Phylogenetic relationships are inferred from DNA sequences from both the plastid (the rps16 intron) and the nuclear (ITS, intron of the RPB2 gene) genomes. LÄS MER

  4. 4. Plant Species Composition and Diversity in Cliff and Mountain Ecosystems

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Henrik Antonsson; Göteborgs universitet.; Gothenburg University.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cliff ecology; bryophytes; biodiversity; beta diversity; dispersal; facilitation; nurse plant; plant-plant interactions; Silene acaulis; stress;

    Sammanfattning : Ecosystems today are under increasing pressure from a rapidly changing climate, changes in land-use, habitat fragmentation and degradation and increasing anthropogenic disturbance. Studying drivers of biodiversity patterns is of increasing importance for understanding the dynamics of communities and their reactions and adaptation to changes in the future. LÄS MER
