  1. 1. Phylogeny, taxonomy and species delimitation of water mites and velvet mites

    University dissertation from Stockholm : Department of Zoology, Stockholm University

    Author : Jeanette Stålstedt; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acariformes; Parasitengona; Hydrachnidia; Trombidia; water mites; velvet mites; taxonomy; cryptic species; species delimitation; DNA; GMYC; experimental rearing; new synonyms; distribution; phylogeny; revised classification; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Abstract : This study is part of the Swedish Taxonomy Initiative (STI) - one of the most ambitious all taxa biodiversity inventories in the world. One of the pillars in STI is to support taxonomic research on the most neglected taxonomic groups with the aim to lift the level of knowledge of biodiversity in the country. READ MORE

  2. 2. Through the magnifying glass - The big small world of marine meiofauna Morphology, species and evolution in Nemertodermatida

    University dissertation from Stockholm : Department of Zoology, Stockholm University

    Author : Inga Meyer-Wachsmuth; Stockholms universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nemertodermatida; Acoelomorpha; morphology; CLSM; Phalloidin; musculature; DNA; cryptic species; species delimitation; dispersal; taxonomy; phylogenetics; IHC; nervous system; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Abstract : Nemertodermatida is a group of microscopic marine worm-like animals that live as part of the marine meiofauna in sandy or muddy sediments; one species lives commensally in a holothurian. These benthic worms were thought to disperse passively with ocean currents, resulting in little speciation and thus wide or even cosmopolitan distributions. READ MORE

  3. 3. Contributions to the understanding of diversity and evolution in the genus Coreomyces

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Henrik Sundberg; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ascomycetes; Coreomyces; Corixidae. DNA; DNA extraction; Fungi; ge-nome; host specificity; Laboulbeniales; mating types; MAT-loci; meth-odology; NGS; parasite; position specificity; systematics; taxonomy; Biology with specialization in Systematics; Biologi med inriktning mot systematik; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi;

    Abstract : The Laboulbeniales is an order of enigmatic ascomycete fungi that are obligate microscopic parasites of arthropods, which are usually non-detrimental. They typically display a high degree of host specificity, and the genus Coreomyces, which is the recurring theme of this thesis, is no exception. READ MORE

  4. 4. Geographic differentiation and population history in Silene dioica and S. hifacensis: variation in chloroplast DNA and allozymes

    University dissertation from Department of Systematic Botany, Östra Vallgatan 14-20, 223 61 Lund, Sweden

    Author : Ursula Malm; Lund University.; Lunds universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; morphology; taxonomy; Systematic botany; conservation biology; endemic; chloroplast DNA; allozyme; hybridization; gene flow; geographic variation; postglacial migration; genetic diversity; Silene; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .;

    Abstract : In this thesis I used allozymes and PCR-RFLP analysis of chloroplast DNA (cpDNA) to investigate geographic differentiation within the widespread Silene dioica (L.) Clairv. (Caryophyllaceae) and the narrowly-distributed S. hifacensis Rouy ex Willk. READ MORE

  5. 5. 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
