  1. 31. Environmental sequencing to infer patterns of eukaryotic evolution : Combining long-read and short-read metabarcoding

    Författare :Mahwash Jamy; Fabien Burki; Micah Dunthorn; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protists; eukaryotes; environmental sequencing; ribosomal DNA; PacBio; long-read metabarcoding; phylogenetics; salt barrier; habitat evolution; eukaryotes evolution; evolutionary rate; Apicomplexa; pathogen; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Sammanfattning : Our view of eukaryotes is biased towards plants, animals, and fungi. But the vast majority of eukaryotic diversity is microbial in nature. These microbial eukaryotes are key players in all ecosystems on earth and are collectively known as protists. LÄS MER

  3. 32. Evolutionary Perspectives on Naidinae (Annelida, Clitellata, Naididae): Molecular and Morphological Revelations

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Naididae; Naidinae; phylogenetics; molecular systematics; morphology; ultrastructure; Biology; Biologi; systematisk zoologi; Systematic Zoology;

    Sammanfattning : Naidinae is a group of tiny oligochaetous clitellates, common all over the world, primarily in freshwater. The taxon includes about 180 nominal species. LÄS MER

  4. 33. Systematics and phylogenetics of the Blepharispermum group (Asteraceae - Heliantheae)

    Författare :Torsten Eriksson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fylogeni;

    Sammanfattning : This thesis treats the Blepharispermum group which comprises the three genera Athroisma DC., Blepharispermum Wight ex DC., and Leucoblepharis Arnott. The systematic position of the group within the Asteraceae is discussed, and a transfer is proposed from the tribe Inuleae, where it was placed earlier, to the Heliantheae. LÄS MER

  5. 34. Phylogenetics and taxonomy of the Gorteria clade (Asteraceae-Arctotideae)

    Författare :Frida Stångberg; Arne Anderberg; Christoph Oberprieler; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; växtsystematik; Plant Systematics;

    Sammanfattning : This thesis deals with the systematics of the Gorteria-Gazania-Hirpicium-clade within the tribe Arctotideae-Gorteriinae in the angiosperm family Asteraceae. The group is found in southern Africa, with many representatives in the Greater Cape Floristic Region in South Africa, an area known for its high species richness and endemism. LÄS MER
