  1. 1. Evolutionary and mechanistic aspects of insect host plant preference

    Författare :Alexander Schäpers; Niklas Janz; Steven Heard; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; host plant choice; host range; diet breadth; butterfly; oviposition; specialist; generalist; insect-plant interaction; search behavior; olfaction; decision making; evolution; parasite-host interaction; zoologisk ekologi; Animal Ecology;

    Sammanfattning : Plant feeding insects comprise about 25% of all animal species on earth and play an important role in all ecosystems. Although we understand that their association with plants is a key-factor driving the diversification in this group, we still have large gaps in our knowledge of the underlying processes of this relationship.

  3. 2. The plasticity and geography of host use and the diversification of butterflies

    Författare :Jessica Slove Davidson; Niklas Janz; Tommi Nyman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nymphalidae; host range; phylogeny; distribution; latitude; phylogeography; local specialisation; colonisation; host shift; polyphagy; speciation; diversification; zoologisk ekologi; Animal Ecology;

    Sammanfattning : Our world is changing rapidly and factors like urbanisation, changed agricultural practices and climate change are causing losses in butterfly diversity. It is therefore of importance to understand the source of their diversity. LÄS MER

  4. 3. Evolutionary genomics of host-microbe interactions

    Författare :Elin Videvall; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; host; microbiota; avian malaria; ostrich; parasite; dual RNA-seq;

    Sammanfattning : The microbes living inside hosts have highly important consequences for host health and fitness. From the host’s perspective, some microbes exhibit mutualistic tendencies, others parasitic, and some commensal, but this is context-dependent and opportunistic lifestyles are widespread in nature.

  5. 4. Adenovirus-host interactions : implications for tropism and therapy

    Författare :Annasara Lenman; Niklas Arnberg; Lennart Svensson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adenoviridae; Amino Acids; Antiviral Agents; Epithelial Cells; Factor IX;

    Sammanfattning : Human adenoviruses (HAdVs) are common viruses often associated withgastrointestinal, ocular and respiratory infections. They can infect a widevariety of cells, both dividing and non-dividing. HAdVs attach to and infecttarget cells through interactions with cellular receptors. LÄS MER

  7. 5. Diversity of aquatic viruses from genes to host interactions

    Författare :Emelie Nilsson; Karin Holmfeldt; Martha Clokie; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microbial ecology; bacteriophage; ‘omics; isolation; host range; temporal variation; deep biosphere; Baltic Sea; Akvatisk ekologi; Aquatic Ecology; Mikrobiologi; Microbiology;

    Sammanfattning : Viruses are the most numerous entities on Earth, and can be found in all waters. In aquatic ecosystems, viruses are key players since they alter the way energy and nutrients are transferred by killing larger organisms. LÄS MER
