  1. 1. Taxonomy and Phylogeny of Catenulida (Platyhelminthes) with Emphasis on the Swedish Fauna

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Karolina Larsson; Uppsala universitet.; [2008]
    Keywords : Biology; taxonomy; phylogeny; molecular phylogenies; cryptic species; micro-invertebrate; Biologi; Catenulida; Platyhelminthes;

    Abstract : This thesis focuses on phylogenetic and taxonomic studies of Catenulida (Platyhelminthes). Catenulida is a group of microscopic free-living worms mainly found in freshwater habitats. The Swedish catenulid fauna was previously virtually unknown. READ MORE

  2. 2. Phylogeny and Taxonomy of Childia (Acoela) New characters for unraveling acoel phylogenies from molecules, ultrastructure, immunocytochemistry and confocal microscopy

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Yonas Isaak Tekle; Uppsala universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Childiidae; Childia; Paraphanostoma; Acoela; phylogeny; taxonomy; morphology; 18S rRNA; 28S rRNA; Histone H3; ultrastructure; confocal; phalloidin; immunocytochemistry; Biologi; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi;

    Abstract : This thesis presents a comprehensive phylogenetic and taxonomic study of an acoel subgroup, the Childiidae. Members of this taxon are characterized by well-developed male copulatory organs with conical/cylindrical stylets. READ MORE

  3. 3. Integrative taxonomy of birds : Studies into the nature, origin and delimitation of species

    University dissertation from Stockholm : Department of Zoology, Stockholm University

    Author : George Sangster; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aves; biogeography; integrative taxonomy; pluralism; ring species; speciation; species criteria; species limits; taxon chain; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Abstract : Species are the basic currency in biodiversity studies but what constitutes a species has long been controversial. A major breakthough was the insight that most systematists agree that species are segments of population lineages, and that multiple lines of evidence should be employed and integrated, a procedure called integrative taxonomy.

  4. 4. Phylogeny and Taxonomy of Polyblastia and allied taxa (Verrucariaceae)

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sanja Savić; Uppsala universitet.; [2007]
    Keywords : Biology; Phylogeny; Taxonomy; ITS; LSU; RPB1; Nomenclature; Biologi; Polyblastia; Verrucariaceae; Sporodictyon; Atla; Thelidium; Verrucaria; Staurothele; Trimmatothele;

    Abstract : 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. READ MORE

  5. 5. Systematics of Marionina (Annelida: Clitellata: Enchytraeidae)

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lisa Matamoros; Göteborgs universitet.; Gothenburg University.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Marionina; Michaelsena; Enchytronia; Enchytraeidae; cryptic species; molecular phylogeny; taxonomy; systematics; genetic diversity;

    Abstract : This thesis is about species of segmented worms that previously were placed in the genus Marionina Michaelsen, 1890, within the family Enchytraeidae, class Clitellata and phylum Annelida. These species are closely related to earthworms, but are much smaller and many of them are found between the sand grains in marine beaches. READ MORE
