    Abstract : Popular Abstract in Swedish Anatomi och taxonomi för ca 125 cetrarioida lavar är undersökt. Gruppen består av släktet Cetraria (islandslavar) i vid bemärkelse. Speciell tonvikt har lagts på reproduktiva strukturer som sporsäckar och konidier. 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. Taxonomy and phylogeny of Randia (Rubiaceae, Gardenieae)

    University dissertation from Göteborg : University of Gothenburg

    Author : Claes G. R. Gustafsson; Göteborgs universitet.; Gothenburg University.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; botany; taxonomy; phylogeny;

    Abstract : The Neotropical genera Rosenbergiodendron and Randia have been studied. Rosenbergiodendron is revised and presented in a separate paper. The other three papers concern Randia, which is partly revised and phylogenetically analysed. Rosenbergiodendron is morphologically distinct and cannot be synonymised under Randia. READ MORE

  5. 5. A Taxonomy and Design Methodology for Hybrid Memory Systems

    University dissertation from Göteborg : University of Gothenburg

    Author : Dmitry Knyaginin; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Taxonomy; Non-Volatile Memory; Performance; System-Level Models; Methodology; Design Space Exploration; Energy Efficiency; DRAM;

    Abstract : The number of concurrently executing processes and their memory demandin multicore systems continue to grow. Larger and still fast mainmemory is needed for meeting the demand and avoiding an increase inbacking store accesses that are much slower and less energy efficientthan main memory accesses. READ MORE
