  1. 6. Adenovirus species B: receptors, tropism and hematopoietic cells

    Författare :Anna Segerman; Göran Wadell; Ya-Fang Mei; Urs Greber; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; Adenovirus; Species B; hematopoietic; Mikrobiologi; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar; medicinsk virologi; Medical Virology;

    Sammanfattning : At present, the human adenoviruses (Ads) comprise 51 members, which have been classified into six species (A to F). In general, adenovirus (Ad) tissue tropism or disease patterns vary according to species, although adenoviruses from different species can sometimes cause the same symptoms. LÄS MER

  3. 7. Grassland restoration : Connectivity, plant community change and cows

    Författare :Rozália E. Kapás; Sara Cousins; Adam Kimberley; Lars A. Brudvig; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; biodiversity; colonization; connectivity; dispersal; distance to species pool; diversity; grassland restoration; grassland specialist species; grazing livestock; habitat availability; plant community composition; restoration; semi-natural grassland; species richness; naturgeografi; Physical Geography;

    Sammanfattning : The ecological significance of semi-natural grasslands is high because these habitats provide a home for a diverse flora and fauna and support a range of associated ecosystem services. Due to large-scale land-use changes the extent of grassland habitat has declined. LÄS MER

  4. 8. Species Responses to Environmental Fluctuations : impacts of food web interactions and noise color

    Författare :Sara Gudmundson; Uno Wennergren; Anna Eklöf; Sebastian Diehl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Species constantly experience changes in their environmental conditions owing to natural or human induces reasons. Understanding how species respond to these fluctuations are important for ecology, especially given the ongoing climate change. Empirical studies have shown that species respond differently to the same disturbance. LÄS MER

  5. 9. Taxonomy and Systematics of Thelephorales – Glimpses Into its Hidden Hyperdiversity

    Författare :Sten Svantesson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thelephorales; Tomentella; Polyozellus; Pseudotomentella; Amaurodon; Hydnellum; Sarcodon; species delimitation; cryptic species; molecular systematics; ectomycorrhiza; basidiomata shape;

    Sammanfattning : The order Thelephorales is a widespread group of many thousands of species of ecologically important, ectomycorrhizal fungi, of which only a fraction have been described to date. Most species are corticioid (skin-like) and form complexes of morphologically similar, closely related species. LÄS MER

  7. 10. Metapopulation and metacommunity processes, dispersal strategies and life-history trade-offs in epiphytes

    Författare :Swantje Löbel; Håkan Rydin; Tord Snäll; Lars E. Ericson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; asexual; biodiversity; bryophytes; dispersal limitation; establishment; evolution of reproductive traits; germination; growth; habitat fragmentation; landscape dynamics; local processes; patch-tracking; pH; reproduction; species richness; species interactions; Other biology; Övrig biologi; Ecological Botany; Ekologisk botanik;

    Sammanfattning : The aim of this thesis was to increase knowledge about metapopulation and metacommunity processes in patchy, dynamic landscapes, using epiphytic bryophytes as a model system. Host trees and deciduous forest stands in the coniferous landscape are patchy, temporal and undergo changes in habitat quality during succession. LÄS MER
