  3. 2. Factors Affecting the Distribution of Rocky-Shore Macroalgae on the Swedish Coast : Morphological, Physiological, Reproductive and Genetic Aspects

    Författare :Gustav Johansson; John Raven; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : The aim of this thesis was to examine factors affecting the distribution of macroalgal species both vertically (depth zonation) and geographically along the Baltic Sea salinity gradient. Interactions between the physical environment and basic biological traits of the algae are emphasised. LÄS MER

  4. 3. Phylogeny, taxonomy and species delimitation of water mites and velvet mites

    Författare :Jeanette Stålstedt; Johannes Bergsten; Fredrik Ronquist; Joanna Mąkol; Ashley Dowling; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. The lichen genus Candelariella in western North America

    Författare :Martin Westberg; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phylogeny; ITS rDNA; Systematic botany; taxonomy; morphology; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; distribution; anatomy; Candelariaceae; Candelariella; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .;

    Sammanfattning : The lichen genus Candelariella comprises crustose to small squamulose members of the family Candelariaceae. The genus currently includes c. 50 species world-wide but few studies have treated the taxonomy within this group. In the present thesis the taxonomy of the genus in western North America is treated.

  7. 5. Morphological and electromyographical studies of trapezius myalgia in cleaners

    Författare :Britt Larsson; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; female cleaners; Trapezius myalgia; work-related; arbetsmiljömedicin; Yrkesmedicin; industrial medicine; Occupational health; morphological analysis and surface-EMG;

    Sammanfattning : Pathomechanisms of work-related myalgia are poorly understood. Myalgia is caused by exitation of nociceptors present in the muscular tissue but not in the muscle fibres themselves. Morphological analysis can contribute to knowledge of excitation of nociceptors. Surface EMG is a widely used method in the research field of ergonomics. LÄS MER
